Definitions
- the invention relates to a location and navigation device for a motor vehicle according to the preamble of the main claim.
- Various location and navigation devices are already known in which a current vehicle position is shown on a road map of a display device and the position is continuously coupled.
- Such a device is known, for example, from Bosch Technical Reports, Volume 8, 1986, Issue 1/2, 'EVA - an Autonomous Location and Navigation System for Land Vehicles', pages 7-14.
- a satellite navigation system under the GPS system Global Position System
- the position determination with the GPS system only has an accuracy of approx. 100 m for the approved general applications.
- the accuracy also depends on the altitude and the number of satellites received. In urban areas where perfect satellite reception is not always guaranteed, positioning is therefore not always possible.
- the "Travelpilot" that the magnetic field probe is disturbed by magnetizing influences of the vehicle or strong magnetic interference. The location is lost when driving on non-digitized areas or when transporting the vehicle on a ferry or train.
- the navigation device must be set up again. Although this can be carried out with a few key operations, it does not take place automatically. This limits the convenience of use.
- the location and navigation device according to the invention with the characterizing features of the main claim has the advantage that an automatic correction of the position can be carried out with the help of the satellite navigation device in the event of loss of location or fault location, which is immediately recognizable on the map of the display. It is particularly advantageous that the positioning of the navigation device, ie the initialization of the current position by the satellite navigation device, also takes place automatically and without the driver having to do anything. This means that the driver is less distracted from the traffic.
- the measures listed in the dependent claims allow advantageous developments and improvements of the location and navigation device specified in the main claim.
- the scattering range for the satellite location By determining the scattering range for the satellite location, it is advantageously possible to delimit the error that can be detected in the exact position determination of the vehicle. Because the accuracy of satellite tracking u. a. A relatively reliable range for the vehicle position can be determined essentially depending on the number and the constellation of the satellites received at the same time. The vehicle position is refined / optimized by comparison (map matching) after a plausibility check on the road map shown. If the road currently used according to coupling location and map matching is located in the spreading region of satellite location, it can advantageously be assumed that the vehicle position, which is managed by the system (location and navigation system), is correct.
- the satellite location is shown on the display. This also enables the driver to get an idea of the measured position in relation to the road map shown.
- the position of the vehicle on the road map shown can then also be corrected by simple manual correction using corresponding cursor keys.
- FIG. 1 shows a block diagram
- FIG. 2 shows a flow diagram for the functional sequence
- FIGS. 3-6 show examples of various corrective measures.
- the block diagram of FIG. 1 shows a controller 20 which is connected to a display 26 and control elements 27.
- the controller 20 is connected to various sensors 3, such as a displacement sensor 22, an angle sensor 23, a compass 24 and a satellite navigation device 25.
- the controller 20 is connected to a map memory 21, on which the road maps are primarily digitally stored .
- the controller 20 contains a microcomputer and internal memory, such a device is known for example from the "Travelpilot" and therefore need not be described in detail.
- a compact disk memory is used as the map memory 21, on which, among other things, the road map data of Germany are stored.
- the vehicle position on the road map is indicated by a flashing arrow below which the road map moves when the vehicle is moving forward.
- the current position is calculated using two wheel sensors on one axle, from whose digital impulses distances and angular movements of the vehicle are calculated.
- a two-axis magnetometer is arranged in the vehicle, which determines the direction of travel with respect to the north direction from the earth's magnetic field. Map matching compares the geographic compass position with the coupled position on the map and a plausibility check determines the current vehicle position on the road.
- a satellite navigation device 25 is known as a GPS receiver (Global Position System). Depending on its position on the earth's surface, the GPS receiver 25 receives the signals from at least three satellites of the GPS system and calculates its position on the earth's surface based on signal propagation times. This position information is entered into the controller 20.
- GPS receiver Global Position System
- the coupling location receives road data stored on a compact disk (CD) from a map memory 21 and has been prepared for the control 20 by a map processing unit 13. This prepared road data is shown on the display 26 as a road map.
- the coupling location 4 checks the plausibility of the determined vehicle position and gives the vehicle position to the map processing unit 13. A flashing arrow for the vehicle position then appears on the display 26, for example, on the road just traveled on.
- the satellite receiver 25 now receives the satellite signals via the antenna 1 and first determines a position for the vehicle therefrom independently of the coupling location. In position 6, the satellite location is synchronized with the coupling location. This is necessary because the vehicle continues to move during the calculation time and has in the meantime assumed a different position. After a transformation of the values into the coordinate system of the coupling location (position 7), a difference vector V is now calculated in position 8 from these values, which indicates the difference between the coupling location and the satellite location.
- the available GPS satellite system is freely accessible to everyone with restrictions.
- the limitation is that the accuracy of the position determined by the satellites has a range of spread.
- the scattering range depends on the number of satellites received at the same time and can have a circle with a radius of 100 m or considerably more.
- This tolerance which is too great for determining the position of a vehicle, can now be improved with the aid of a low-pass filter (position 9).
- the time constant of the low-pass filter is selected so that interference signals from the GPS system are partially suppressed on the one hand, and on the other hand a loss of location due to the movement of the vehicle is recognized as quickly as possible. A compromise must be made between these two extreme values, which is advantageously determined empirically.
- the value filtered by the low-pass filter is used to calculate an optimized satellite positioning position. Since, based on empirically determined values, at least four (in exceptional cases also 3) satellites received simultaneously, the Scattering range can be estimated relatively accurately, this results in a quality factor for the position determined by the satellites. A range of this position can now be determined on the basis of empirically determined values. The spreading range is determined in position 5. The values determined in position 10 are transferred to the card processing unit 13. The vehicle position and / or additionally the position determined by the satellite can now be shown on the display 26.
- FIG. 3 shows a road 32, a vehicle located next to the road with a coupling location 30 and a satellite location 31.
- a scattering area 34 is shown as a circle, which should represent the area of uncertainty for the satellite location 31 and was determined with the aid of the quality factor .
- a vector V which represents the deviation between the two location methods, is drawn between the coupling location 30 and the satellite location 31. Since the coupling location is outside the spread of the satellite location, it is now assumed that the coupling location 30 is incorrect. This can arise, for example, if the vehicle compass 24 has determined a rejection due to magnetization influences.
- the GPS position is now adopted as a new coupling location position (support) with subsequent map support (map matching), as described below for FIG. 3. It is assumed in FIG. 3 that the vehicle must set up its coupling device again.
- the position for the coupling location 30 is now corrected by the satellite location according to FIG. 4.
- FIG. 4 now shows that the new vehicle position is determined by satellite location 31.
- the scattering region 34 is again drawn in around the satellite location 31.
- the road 32 on which the vehicle is actually located after a corresponding plausibility check now runs within the scattering area 34.
- a correction is now made within map region 34 by means of map matching, so that the vehicle on the road map is moved in parallel from satellite location 31 to current position 33.
- This current position 33 found in this way is continued for further coupling location.
- the vehicle is within the range 34 and on a road within certain limits, there is no GPS correction, since in this area the vehicle is only guided by the stored map data in connection with the vehicle sensors and the compass.
- FIG. 5 shows an exemplary embodiment in which a loss of position in the coupling location has occurred, but the vehicle is still within the satellite scattering range. However, the coupling location system no longer finds its way back to road 32 due to the loss of the correction position.
- a locating position 52 and its scattering range for the vehicle are calculated again.
- map matching now assumes the satellite position 52 as the current vehicle position and the vehicle is placed on the road 32 in parallel in position 53. In this area similar to that of FIG. 4, the further positive feedback is now continued by the locating and navigation device of the vehicle.
- the GPS position and its scattering range are preferably calculated continuously in order to control the coupling location.
- This locating and navigation device which works in a fully automatic manner, no longer requires manual mounting of the vehicle.
- cursor keys for controlling the vehicle position, for example to carry out a fine adjustment.
