The importance of Web 2.0 applications can be demonstrated by their membership, popularity and frequency of use. Facebook is the largest social network with about five hundred million registered users in February 2010. Among the ten most visited sites in the same period, according to web site access data collected by web user-gathering and performing server services, Alexa included Blogger.com, Facebook, Wikipedia and YouTube four applications of Web 2.0, which are particularly often used by young visitors aged fourteen to 29 years.

The economic success of the applications has not yet set in spite of high expectations. Sales are thus lagging behind the theoretical market valuations, which can be calculated on the basis of the respective financing rounds of companies that are mostly not listed on the stock market. Business leaders are still looking for the right business model.

As
http://de.wikipedia.org/wiki/On-Board-Diagnose
Removable, in the automotive industry, the O [n] B [oard-] D [iagnose] standard for vehicle diagnosis is known.

While driving, all emission control systems are monitored, In addition, other important ECUs whose data are accessible through their software. Any errors that occur are displayed to the driver via a warning light and stored permanently in the respective control unit.

Error messages can then be queried later by a specialist workshop via standardized interfaces. The codes (= so-called P codes) are defined in ISO standard 15031-6. Access for vehicle diagnostics via OBD-2 is the vehicle's 16-pin OBD-2 diagnostic socket, which is often used not only for the multi-vendor, exhaust-related OBD-2 diagnostic protocol, but also for the manufacturer's specific diagnostics protocols.

The results of the on-board diagnostics can also be read out by special software applications on commercially available notebooks. Via the diagnostic interface, the connected workshop or notebook computer sends (via additional required protocol interpretation and signal level conversion hardware) commands to one of the ECUs, which is activated via its address, and then receives results back.

Among other things, commands are available for reading the ID (precise model name and version) of the ECU, for reading and resetting the above-mentioned error entries, for reading so-called measured value blocks (also called standard displays), for reading, testing and setting various setting parameters (so-called adaption channels) and (especially for development) for direct reading and writing of memory cells in the control unit.

Well known in the art for transmitting data between devices over a short distance is the Bluetooth standard, cf. for example
http://de.wikipedia.org/wiki/Bluetooth

As
http://de.wikipedia.org/wiki/App
Removable, the term App (short for application) generally refers to any form of application program. In linguistic usage, however, these meanwhile mostly mean applications for modern smartphones and tablet computers, which can be procured via an online shop integrated in the operating system and thus installed directly on the smartphone.

These online shops include Apple's App Store, the Windows Phone Marketplace by Microsoft, Google's Android Market, Nokia's Ovi Store, RIM's AppWorld for the Blackberry devices, and Sony Ericsson's PlayNow or the Samsung Apps.

The conservation of our planet by reducing pollutants in soil, water and air is becoming increasingly important. Increasing global warming is having a particularly negative effect on the planet's ecosystem due to the ever-increasing emission of carbon dioxide (CO ₂ ).

Carbon dioxide is produced especially when burning fossil materials such as oil, gas or coal. This combustion takes place mainly in power generation in power plants and in petrol or diesel-powered motor vehicles (motor vehicles).

As part of international efforts, regulations and solutions are to be found to curb global warming by reducing carbon dioxide emissions. But it is growing not only among governments, but also among the population or each individual, that each individual can and must contribute to the reduction of carbon dioxide by saving electrical energy and fossil fuels.

Pollutant reductions of the air, especially with regard to carbon dioxide, can be achieved for motor vehicles with internal combustion engines on the one hand by the development of more efficient and thus more economical engines, on the other hand also by a more conscious, energy-saving driving.

In addition to the necessary environmental awareness described above, most people have a natural cost awareness, that is the interest to spend as little money for a purchased service or product.

When buying a motor vehicle, in addition to the purchase price, the consumption values according to the manufacturer's information are usually taken into account. This gives the customer a feeling about the running fuel costs. Experience has shown that the consumption data of the manufacturers in practice, however, hardly achieved, that is, the real consumption is above the idealized consumption according to the manufacturer's brochure.

At the present time no statistics are known which contain real consumption values of motor vehicles after delivery to the customer (of individual values in the context of Apart from comparative tests).

Likewise, there are no available statistics on real or minimum consumption depending on the specific route - statistics that indicate what minimum consumption can be achieved on a given route with a given vehicle with optimal driving.

Presentation of the present invention: object, solution, advantages

Based on the disadvantages and inadequacies set out above and in appreciation of the state of the art outlined above, the object of the present invention is to provide a system and a method by means of which real fuel consumption values for all motor vehicles on all routes with the permanent goal of finding Consumption and thus minimum carbon dioxide can be displayed and replaced.

This object is achieved by a system having the features specified in claim 1 and by a method having the features specified in claim 10. Advantageous embodiments and expedient developments of the present invention are characterized in the respective subclaims.

The present invention is based on the determination of the real fuel consumption values of a motor vehicle on a certain route and on the corresponding visualization of these values, in particular in a, for example global, Internet portal, by means of which the combined vehicle diagnostic and geoposition data are visualized via the O [n-] B [oard-] D [iagnose] port of the vehicle on the one hand and a Geopositionsempfänger on the other hand can be read and transmitted via a mobile phone connection to a server.

Preferably, the diagnostic data can be queried initiated by a smartphone app and then transferred to the portal.

Advantageously, the transmission of the determined data for reducing the amount of data in bundled and / or compressed form can take place.

Conveniently, the transmission may be triggered by geolocalized triggers and, for this purpose, ranges / positions may be defined that include such Trigger transmission (Location Based Transmission).

Preferably, a so-called n: m assignment ("n to m") between terminals and system user accounts can be used - a terminal can have multiple users, each user can use multiple terminals.

In an advantageous manner (instead of the smartphone), a telematics or mobile radio module already installed in the motor vehicle can be used, and it is precisely this module which can interrogate the diagnostic data via OBD or directly from the controller A [rea] N [etwork] bus.

Conveniently, the geoposition of the corresponding receiver can be used in the smartphone.

In a preferred manner, the geoposition can be used by a receiver installed in the vehicle, which can be queried, for example, directly by a telematics module via controller A [rea] N [etwork].

In an advantageous manner, the data transmission between the OBD connection and the smartphone can take place via an OBD Bluetooth adapter.

Conveniently, the Internet portal may display distance-based leaderboards (for example, in the form of "top ten") of fuel consumption values.

Preferably, the comparability on the basis of the traffic flow and the weather conditions can be made by the inclusion of information provided by third parties.

Advantageously, the consumption comparison values can be calculated per overlapping route sections.

Conveniently, the sections may have a minimum length, for example at least one kilometer or at least ten kilometers.

Preferably, the consumption comparison values and leaderboards can be specified per route section per vehicle class (compact car, middle class, upper middle class, upper class, sports car, commercial vehicle class).

Advantageously, the consumption best lists per vehicle can be specified.

Conveniently, the fuel consumption lists per vehicle and per engine can be specified.

In a preferred manner, total route lists per country, per manufacturer, per vehicle class, per vehicle, per vehicle and per engine can be created independently of the route.

Advantageously, at certain intervals, for example once a year, the most fuel-efficient vehicles can be chosen.

Conveniently, "fuel saving competitions" for selected routes, for example Hamburg - Munich, may be tendered for a certain period of time.

In a preferred manner, the Internet portal can send registered users the current best consumption for the current route section while driving. In addition, other driving recommendations can be sent, for example, the previously determined best engine speed and speed.

In principle, the consumption values could be determined manually, that is to say by the user or driver, either by using the on-board computer (if present) or by explicitly refueling after completion of the traveled route and subsequent calculation.

These manual methods are not only very inaccurate, but also easily offer the possibility of deliberate data corruption by the user (wrong car type, wrong route, wrong consumption). Thus, no reliable data collection is possible and thus the success of the Internet portal is questionable.

This problem avoids the present invention in that reliable data are read out of the vehicle via the standardized O [n] B [oard-] D [iagnosis] interface. These are at least the vehicle type (make, model, year of manufacture, engine, etc.) and the fuel-air mixture, which is the basis for the fuel consumption calculation.

The data is read out via a standard OBD adapter, which uses Bluetooth or USB to transfer the data to a paired smartphone or to a permanently installed one Telematics box or alternatively to a notebook or a P [ersonal] C [computer] transmits.

Furthermore, in order to obtain reliable data on the distance actually traveled, the smartphone has a receiver for determining the geographical position, for example based on G [lobal] P [ositioning] S [ystem], Galileo, Glonass.

A particular application program or app within the scope of the present invention periodically collects OBD data, geoposition, and time at the same time, for example, every ten seconds, and merges them into a data packet.

These periodically collected data packets can be uploaded from the smartphone or the app directly to the Internet portal or collected in the smartphone and put at a later date by the user in the portal.

A key application of the Internet portal is the comparison of their own, route-specific consumption values with those of other users. Since most car drivers are interested in a constant optimization of their fuel costs, the portal allows the user on the one hand to consider the purchase of a more fuel-efficient vehicle, on the other hand to minimize his driving behavior in terms of fuel consumption compared to identical vehicles.

• minimaler Verbrauch pro Strecke,
• minimaler Verbrauch pro Kfz-Klasse (zum Beispiel Mittelklasse, gehobene Mittelklasse, Oberklasse, ...) und Strecke,
• minimaler Verbrauch pro Kraftstoffart und Strecke,
• minimaler Verbrauch pro Automobilhersteller und Strecke,
• minimaler Verbrauch pro Kfz-Modell und Strecke sowie
• entsprechend gemittelte (und damit streckenunabhängige) Gesamtstatistiken.

The Internet portal can provide a variety of statistics, among others

• minimum consumption per route,
• minimum consumption per vehicle class (for example middle class, upper middle class, upper class, ...) and route,
• minimum consumption per fuel type and route,
• minimum consumption per automaker and route,
• minimum consumption per car model and route as well
• correspondingly averaged (and thus distance-independent) overall statistics.

In this way it is possible, for example, to determine and select the lowest-consumption vehicle per route, per country, per year, etc.

Furthermore, there is the possibility of linking the ascertained data with traffic-related and weather-related road conditions in order to enable a more differentiated evaluation taking into account the influences of the aforementioned factors. This requires the availability of this information through appropriate web services, possibly from a third party.

Likewise it is possible to proclaim fuel saving competitions on selected routes, for example for the route Hamburg - Munich or Paris - Dakar and to provide them with a corresponding price. Since in this case the concrete route is not specified, such a competition would have the lowest fuel consumption and the ideal route to the result.

Finally, the present invention relates to the use of at least one system according to the type and / or a method set forth above for determining and displaying fuel consumption values of the motor vehicle determined by the diagnostic data on at least one route of the motor vehicle determined by the geoposition data. These combined vehicle diagnostic and geoposition data can be visualized by means of at least one, in particular global, Internet portal.

Best way to carry out the present invention

Fig. 1 illustrates the basic operation of the present invention by means of a system 10 according to the present invention, which operates according to the method according to the present invention.

The first O [n] B [oard] D [iagnose] systems were introduced in the USA as early as 1988 with the aim of being able to monitor compliance with the emissions regulations. In Europe, the existence of an OBD implementation for the registration of new vehicles for gasoline engines has been mandatory since 2001, for diesel vehicles since 2004.

This obligation includes in particular the display of a so-called engine indicator light (MIL = Malfunction Indicator Light) in the field of vision of the driver; This engine warning light indicates errors in the engine electronics and thus in the exhaust gas behavior.

It is also a requirement that exhaust gas-relevant faults can be recorded in a memory and read out via a standardized plug and a serial interface. However, this interface not only outputs stored (error) values but also a large number of current vehicle, engine and exhaust gas-relevant data records.

In the context of the present invention, an OBD-B [lue] T [ooth] adapter 2 (cf. FIG. 2) is attached to the OBD socket 1 of the vehicle 20, which is generally located in the interior of the vehicle 20 below the dashboard on the driver's side , Fig. 2A ) or an OBD-U [universal] S [erial] B [us] adapter 2 (cf. Fig. 2B ) connected. However, alternative or further adapters, for example of the type OBD-Sub D, are also conceivable.

For the present invention, in particular, the OBD-B [lue] T [ooth] adapter (cf. Fig. 2A ) is very advantageous because it allows particularly easy access to the desired data. But other approaches to the vehicle-specific data sets are conceivable, for example, by other adapters directly to the bus of the vehicle 20, for example, on the C [ontroller] A [rea] N [etwork] -Bus or Flexray accessed.

The adapter 2 is now coupled with a smartphone 4, in which also Bluetooth 3 is switched on (so-called "pairing"). An application according to the invention on the smartphone (so-called App 5) is started by the user or driver.

In the next step, vehicle-specific data such as manufacturer, model, year of manufacture, engine are read out via the OBD-B [lue] T [ooth] adapter 2, preferably via the V [ehicle] I [dentification] N [umber] Part of the OBD parameter set. To start recording the consumption values, the user or driver actuates the corresponding button of the app.

Now at least the fuel-air mixture is read out at periodic intervals, for example every ten seconds, via the OBD interface. Further data may be the engine speed and the outside temperature. The interval for reading out the data is assumed to be exemplary with ten seconds within the scope of the further explanations, but shorter intervals may also be expedient.

In addition to the aforementioned OBD data, the geoposition and the time are read out directly via the smartphone 4 at the same time. This results in the simplest case, a data packet from time, geographical longitude, latitude, fuel-air mixture.

The fuel-air mixture is read out via the OBD record M [ass] A [ir] F [low rate]. This record has two bytes (A and B). This results in the calculation of the average fuel consumption per one hundred kilometers according to the known formula to [(A * 256) + B] / 100. The stated calculation of the consumption can be done both in the smartphone 4 directly and on the server 8. In addition, the unique V [ehicle] I [dentification] N [umber] is transmitted for unambiguous assignment within the server application.

The data packets created every ten seconds in the exemplary embodiment can be used for a direct (so-called online mode) via a cellular connection 6, for example via GSM (Global System for Mobile Communications) or UMTS (Universal Mobile Telecommunications System), and / or over the Internet 7 to the server 8 and on the Internet portal 9 are uploaded or initially stored in the smartphone 4 and uploaded at a later date by the user (so-called offline mode). This can then also be done via the smartphone 4 or after transferring the data from the smartphone 4 to a PC over just the latter.

To reduce the amount of data to be transmitted by avoiding excessive transport protocol overhead, a time-delayed live transmission of the data in bursted and / or compressed form is optionally provided. This involves a device-internal collection of the periodically acquired data. These data packets are bundled when certain events occur and / or compressed to the server 8 or to the backend.

• Erreichen einer vorgegebenen Datenmenge im Hinblick auf die Datengröße (zum Beispiel 512 kByte);
• Erreichen einer vorgegebenen Datenmenge im Hinblick auf die Anzahl der Datensätze (zum Beispiel fünfzig Einträge);
• zeitbasiert zyklisch (zum Beispiel alle fünfzehn Minuten);
• manuelles Auslösen durch Betätigen eines hierfür vorgesehenen Buttons innerhalb der App 5;
• automatische Übertragung bei erkanntem längerem Stillstand (= unveränderte GeoPosition); dieser Mechanismus bietet zudem im Allgemeinen eine stabilere Signal- und damit eine verbesserte Übertragungsqualität; dies wiederum bringt eine verminderte Sendewiederholrate und somit ein verringertes Transfervolumen mit sich;
• automatische Übertragung bei Erreichen konfigurierbarer Geopositionen (zum Beispiel Heimatadresse).

Possible events are:

• Achieving a given amount of data in terms of data size (for example, 512 kbytes);
• Reaching a given amount of data in terms of the number of records (for example, fifty entries);
• time-based cyclic (for example, every fifteen minutes);
• manual triggering by pressing a button provided for this purpose within the app 5;
• automatic transmission when a longer standstill is detected (= unchanged geo-position); this mechanism also generally provides a more stable signal and thus improved transmission quality; this in turn implies a reduced retransmission rate and thus a reduced transfer volume;
• automatic transmission upon reaching configurable geopositions (eg home address).

In the case of online transmission, the uploaded data are displayed "live" in the portal 9, thus allowing a tracking of the journeys of the users by visitors of the portal 9, which increases the attractiveness of the portal 9. In the case of a bundled and / or compressed transmission, this live tracking may be delayed.

In order to ensure the reliability of the calculated consumption values and thus to ensure the added value of system 10, namely a reliable consumption statement, the overall system 10 is suitably protected against data manipulation. This applies both in terms of data integrity as well as with regard to the protection of the system 10 against accidental interference (reliability, caused for example by a technical defect) or against deliberate interference (attack security) in the functionality.

In addition to the use of proven in practice, preferably non-proprietary, standard software at all relevant interfaces of the system 10, in particular in the field of telematics protocol and the database management system used, this concerns above all the protection of the data recorded in the vehicle 20 by suitable cryptographic Method.

For this purpose, a message authentication code using a symmetric method can be used in an advantageous manner. Without knowledge of the secret key, this does not make it possible to manipulate a generated data record or to generate new - valid - data records.

The display of the uploaded data records in the portal 9 takes place on a geographical map and / or road map (for example, Google Maps, Open Street Map). The corresponding "mapping" is possible through the geopositions read in the form of distance-dependent statistics, which are visualized on the portal 9. As a result, according to the invention, a route-dependent consumption value comparison ("benchmark") can be carried out.

The Internet portal 9 operates on a user account basis, that is, the user has access to a specific user assigned to this specific user after registration and registration. The term "user" is defined here by the system-wide unique eMail address that has to be entered during the account registration.

Individual terminals are identified via the aforementioned V [ehicle] I [dentification] N [umber], which is transmitted together with the user data as part of the data transmission. An unambiguous assignment of acquired data to a specific terminal / vehicle 20 can take place via this.

User accounts can be linked to one or more devices. This allows a user-based statistical evaluation. Especially about the possibility assigning individual terminals multiple user accounts (shared vehicle 20, for example, in the context of car sharing), the overall system 10 offers the opportunity to contrast the influence of individual driving styles.

Such multi-user operation of the vehicle 20 requires a terminal-side configuration option. This can take place on the one hand via a suitable surface (M [ensch] M [aschine] I [nterface]), on the other hand, however, by further identification methods commonly used in the automotive sector, such as, for example, driver recognition by the key used.

The Internet portal 9 requires a user registration in a known manner (username, password). There is a distinction between a free ("Basic Member") and a paid ("Premium Member") membership, the latter having extended features.

For example, it is possible for the premium member to manage several vehicles 20 under his account and to obtain extended information and statistics on the placements, users, vehicles 20 and / or routes.

Another advantage is the possibility of using a return channel from the portal 9 to the smartphone 4, which already during driving reports driving recommendations based on the previous best values on the corresponding route.

• Am Beispiel einer Autobahn ist der kleinste Streckenabschnitt die Distanz zwischen zwei aufeinanderfolgenden Anschlussstellen. Im innerstädtischen Bereich ist dies die Distanz zwischen zwei Abzweigungen oder Kreuzungen. Aus Gründen der Übersichtlichkeit und der Sinnhaftigkeit können auch Mindestgrößen für Streckenabschnitte definiert werden, zum Beispiel mindestens ein Kilometer außerhalb von Autobahnen oder mindestens zehn Kilometer auf Autobahnen.

To determine the distance-dependent comparison of consumption values (so-called benchmarks), overlapping sections of the route are taken into account on the server 8. Here, a route section in the context of the present invention is defined by the length of the route in the selected direction of travel between branches, junctions, intersections, connection points, etc., cf. Fig. 3 :

• Using the example of a motorway, the smallest section of the route is the distance between two consecutive connection points. In the inner city area, this is the distance between two branches or intersections. For reasons of clarity and reasonableness, it is also possible to define minimum sizes for sections of the route, for example at least one kilometer outside motorways or at least ten kilometers on motorways.

Fig. 4 shows the routes of two users (= User 1, User 2). On the whole of each Driving distance, the above-described data packets were determined and uploaded to the server.

Due to the transmitted geo positions, the routes can be assigned to a road and a corresponding road section. For this purpose, the Internet portal 9 can access a navigation database or road map data.

The consumption values valid for the respective route section, which are available every ten seconds depending on the selected sampling rate, are used to determine the average consumption per hundred kilometers, and the calculated average value in the form of a ranking list, for example a top ten List, displayed in portal 9 directly on the route section (cf. Fig. 4 the example of two drivers).

This consumption list is only valid for one direction of travel. For the direction of travel in the aforementioned data package still the Heading is required, which - can be determined with the Smartphone 4 - within certain limits reliably. Alternatively, the direction can also be determined on the server side from the string of pearls of the position reports.

The opposite direction requires separate statistics; For example, there are very different consumptions on inclines or slopes in the opposite direction.

For realistic consumption comparisons, a distinction can be made between different vehicle classes. Accordingly, separate statistics are possible for upper class, upper middle class, middle class, compact car class. Also conceivable are / is a sports car class and / or a commercial vehicle class. The latter in turn should be subdivided according to the permissible total weight, for example up to 3.5 tonnes, between 3.5 tonnes and 7.5 tonnes etc.

Further, there may be other statistics as shown above. This makes it possible to make objective, independent and reliable statements about the real consumption values of the different vehicles 20 of the different manufacturers.

This information is on the one hand for environmentally and cost-conscious motorists very interesting, on the other hand, a "priceless" marketing argument for these statistics each leading car manufacturers.

The data collected on the server 8 and the associated statistics can be used to send vehicle-specific and route-specific consumption values, if appropriate, including further driving recommendations, for example ideal engine speed and speed, to the user or driver. When taken into account by the driver, an environmentally and cost-conscious driving is promoted even further.
