Description
Technical field
The present invention relates to a kind of motor vehicle module that is used to influence changing of traffic lights, and a kind of method that is used to influence changing of traffic lights, the invention particularly relates to the implementation of the preferential conversion that special vehicle is used on the changing of traffic lights in the scope of street.
Background technology
From the traffic of public passenger's low coverage
Disclose in the field, the circuit of the changing of traffic lights in the scope of street is for example to coordinate by travelling of city motor bus or electric car, so that avoid as far as possible or reduce the waiting time of city motor bus at the changing of traffic lights place.Usually adopt so-called circular point catenary system, so that regulate the pas of public passenger's low coverage vehicular traffic by the radio communication between the control setup of vehicle and changing of traffic lights for this reason.Except the purposes of public passenger's low coverage traffic, this known circular point catenary system also can be used for ambulance vehicles (such as medical truck, fire extinguishing tanker) among a small circle.
In circular point catenary system, each lead to changing of traffic lights, for example get on a bus by the public transport line on the employed traffic route, distribute a series of circular point for described changing of traffic lights from the different spacing of changing of traffic lights.For example the form with radio beacon or infrared ray beacon constitutes described circular point.If the vehicle of corresponding equipment is by first, promptly lead to the circular point farthest of changing of traffic lights, this vehicle then by radio to changing of traffic lights transmit this circular point number.The control setup of changing of traffic lights is by the distance of number discerning vehicle of the circular point that is transmitted, and can therefrom calculate theoretical running time until vehicle arriving signal lamp apparatus place by the vehicle average velociity of the hypothesis of 50km/h for example.Other, be that nearer circular point only is used to revise the theoretical running time that is calculated.Based on this running time until the theory at vehicle arriving signal lamp apparatus place, the control setup of changing of traffic lights is determined the optimal control flow process of changing of traffic lights, so that the green time of the signal lamp group that should influence moves on the vehicle direction of the time of advent, and therefore guaranteed unimpeded travelling for the vehicle of being reported, wherein, the interlude that should consider certainly to stipulate, the shortest green time and the longest waiting time of other traffic participant.
Be used for realizing that for some vehicle this conventional principles of the circular point catenary system of the preferential conversion of changing of traffic lights still has several shortcomings.By changing of traffic lights calculate until the running time at vehicle arriving signal lamp apparatus place vehicle average velociity (such as 50km/h) based on hypothesis.If the actual speed of vehicle is owing to the high or low magnitude of traffic flow or the building ground speed that departs from this hypothesis of highway section in distributing, the running time that is calculated then departs from actual running time, make city motor bus might must wait its green light signals at the traffic signal lamp place, perhaps other traffic participant is then unnecessary muchly by the detention of the green light signals of described city motor bus institute.It is impossible changing the running time that is calculated by changing of traffic lights in this system in short-term.
In addition, the work capacity of exigent planning of described circular point catenary system and preparation.Each running route of vehicle is to captive joint with the circular point of changing of traffic lights, wherein, at first must carry out one-shot measurement for each running route and travel, and a little includes in the distribution graph of highway section so that will circulate a notice of.Must supply the vehicle that uses this running route with corresponding data then.This method determined, should implement again complete planning for running route new or that change, and this is very time-consuming expensive; The change of short time almost is impossible.
Best functional in order to ensure, described circular point catenary system also needs the treatment and the optimization that continue.For also requiring special hardware in this external vehicle of this circular point catenary system, this is directed at high system cost.Another shortcoming is the only unidirectional radio communication connection of leading to changing of traffic lights from vehicle, checks whether changing of traffic lights has received the possibility of automobile wireless electric signal to such an extent as to do not exist.

The specific embodiment
First embodiment of the system of the present invention that is used to influence changing of traffic lights is described according to Fig. 1 now.
In Fig. 1, gathered the system unit that is arranged in the vehicle, and gathered the system unit that is arranged in the changing of traffic lights with 12 with 10.As if vehicle 10 is normally all city motor bus or the such special vehicle of ambulance vehicles.But the present invention also can be used in exclusive traffic.
Arranged in changing of traffic lights 12 to be used for a/s program circuit that the information signal 18 that is received by the receiver of considering by changing of traffic lights 12 16 comes the control setup 14 of control signal lamp apparatus 12 in case of necessity.The information signal 18 that is sent out by vehicle 10 contains the data of relevant vehicle 10 until the running time at arriving signal lamp apparatus 12 places, and/or about crossing the travel direction of changing of traffic lights 12 and the data of turn direction by described vehicle 10.Information signal 18 also selectively contains the preceence code of vehicle 12, so that for example award the absolute priority of ambulance vehicles before every other traffic participant, and/or contain the identifier of vehicle 10, use this identifier that described vehicle 10 is followed the tracks of during its approach signal lamp apparatus 12, and its vehicle from other can be distinguished.
At this moment, the obviously interlude by considering regulation, the shortest green time and the longest waiting time of other traffic participant, the work that comes control signal lamp apparatus 12 by control setup 14.
In vehicle 10, arranged the motor vehicle module formed by control setup 20 and emitter 22.The control setup 20 of motor vehicle module be determine being used for for example resembling the GPS module device 24 of the current position of vehicle 10, for example resemble being used for the conventional speeds sensor determine vehicle 10 present speed device 26 and for example being used for resemble the auto-navigation system determines that the running section of vehicle 10 and the device 28 of changing of traffic lights 12 positions are coupled mutually.The standardized component that in described GPS module 24, speed sensor 26 and auto-navigation system 28, advantageously relates to vehicle 10.
Describe in detail now and be used to influence changing of traffic lights 12, top action principle by the illustrated system of Fig. 1 according to the diagram of circuit of the time trip map of Fig. 3 and Fig. 4.
Vehicle 10 is at first determined the position x that it is current by GPS module 24 and auto-navigation system 28
1With its running section (step S10).So find out by auto-navigation system 28 in step S20, whether the changing of traffic lights 12 that will influence on the vehicle ' highway section is positioned at current position x
1Predetermined distance Δ x
LSA=x
LSA-x
1Within.If this is this situation, flow process is further moved towards step S 30, otherwise system returns step S10 again.If if arrived this changing of traffic lights 12 and this changing of traffic lights 12 also for the work that is correspondingly influenced it by approaching vehicle 10 constitutes if having only changing of traffic lights 12 to be positioned on the vehicle ' highway section certainly within the time that can estimate by described vehicle 10, then further program circuit is only necessary.Also can period of service at interval the threshold value of τ replace the distance, delta x in place
LSAThreshold value, its mode is also in company with counting the present speed of vehicle 10 except the current position of vehicle 10.
In step S30, determine the present speed v of vehicle 10 then by speed sensor 26
1The control setup 20 of motor vehicle module is from the present speed v that so determines of vehicle 10
1With the current position x that so determines
1In, obtain running time τ until vehicle 10 arriving signal lamp apparatus 12 places
1(step S40).
The control setup 20 of motor vehicle module generates a corresponding information signal 18 now, and this information signal 18 is launched by the emitter 22 of motor vehicle module, and receives (step S50) by the receiver 16 of changing of traffic lights 12.This information signal 18 contains data described above, and these data are necessary for the work with changing of traffic lights 12 with the coupling that the preferential conversion that arrives vehicle 10 usefulness is optimized.The control setup 14 of changing of traffic lights 12 for example as the work of the control signal lamp apparatus 12 that gets off, promptly according to vehicle whether early than or be later than normal green time A arriving signal lamp apparatus 12 places, be not subjected to vehicle 10 to be additional to the normal green time A ground of the relevant signal lamp group of changing of traffic lights 12, window B when coming directly before or after normal green time A, to generate an additional green light with influencing.Showed this situation among Fig. 3, promptly basis is at position x
1On the running time τ that obtained
1, vehicle 10 is later than normal green time A ground (the position x of arriving signal lamp apparatus place a little
LSA) (curve α), the control setup 14 of changing of traffic lights 12 thereby window B when generating a green light that adds after normal green time A.
During approach signal lamp apparatus 12, motor vehicle module passes through the speed sensor 26 present speed v of collection vehicle 10 constantly
1(step S60), and control setup 20 is therefrom obtained the corresponding velocity variations Δ v of vehicle.Control setup 20 checks in step S70, whether the velocity variations Δ v of this vehicle of obtaining 10 is positioned at the threshold value Δ v of regulation
MaxOn.
If the velocity variations Δ v of the vehicle of being obtained 10 is positioned at the threshold value Δ v of regulation
MaxUnder, promptly vehicle 10 travels with the speed of approximately constant, and flow process then continues to move towards step S80.The control setup 20 of motor vehicle module determines by GPS module 24 and auto-navigation system 28 that here whether vehicle 10 is by described changing of traffic lights 12.If by described changing of traffic lights 12,10 on vehicle is timely as far as possible for vehicle 10, promptly for example at direct position x after changing of traffic lights 12
3On, report departure (step S90) at changing of traffic lights 12 places by corresponding information signal.If also not by described changing of traffic lights 12, flow process then turns back to step S60 to described in contrast vehicle 10 again, vehicle 10 is monitored near the velocity variations during the changing of traffic lights 12 that will influence at it so that continue.
If definite in step S70, the velocity variations Δ v that is obtained has surpassed the threshold value Δ v of regulation
Max, promptly until the pre-determined running time τ at vehicle arriving signal lamp apparatus 12 places
1Surpass certain yardstick ground and depart from the running time that to expect owing to the speed that is changed now, and therefore window A when the green light of changing of traffic lights 12 not of vehicle 10, arriving these changing of traffic lights 12 places (seeing also the curve β among Fig. 3) within the B, flow process then turns back to step S40.Ask for position x now from vehicle 10
2New running time τ until arriving signal lamp apparatus 12 places
2, and generate and send out the information signal 18 (step S50) of corresponding correction.So as mentioned above, the flow process of step S60-S90 is proceeded.
As from accompanying drawing 1, that can clearly discern in 3 and 4 the above explanation is such, motor vehicle module of the present invention forms the device that can independently determine until the running time that arrives the changing of traffic lights place that will influence, and needn't learn a kind of running route with corresponding running time in advance for this reason, and it is programmed, promptly described system is irrelevant with the running route of fixing regulation.Therefore opposite with routine circular point catenary system, described motor vehicle module also allows variation very in short-term distribution aspect, highway section or the actual driving time aspect is reacted.In addition, described motor vehicle module also allows more accurately to determine the running time until arriving signal lamp apparatus place, because be not based on the car speed of hypothesis, but obtains running time by its actual speed.Because in company with the standardized component (GPS module, speed sensor, auto-navigation system) that counts automobile, cost that need not be too big and expense also can realize preferential conversion by the present invention to motor vehicle module of the present invention in addition.In addition, also can with respect to described circular point catenary system simplify and thereby more expense advantageously realize the control setup of changing of traffic lights because in motor vehicle module, obtain running time until vehicle arriving signal lamp apparatus place.
Now a kind of modification of first embodiment is set forth as second embodiment by accompanying drawing 2.Same parts in accompanying drawing 2, being equipped with among first embodiment that resembles accompanying drawing 1 with identical reference symbol, and identical action principle is no longer set forth.
In this embodiment, the system that is additional to accompanying drawing 1 is equipped with changing of traffic lights 12 with emitter 30, and is equipped with motor vehicle module with receiver 32.Changing of traffic lights 12 sends out one second information signal 31 by this emitter 30 with the time gap of rule, this second information signal contains the data of relevant changing of traffic lights 12 positions that will influence, and is received by the receiver 32 of the motor vehicle module that is positioned near the vehicle 10 the changing of traffic lights 12.
So whether the control setup 20 of motor vehicle module is found out by auto-navigation system 28 be positioned on the running section of vehicle 10 by its changing of traffic lights 12 that has received second information signal 31.If this is this situation, motor vehicle module then generates a first information signal 18 with top by the illustrated mode of first embodiment, and sends it to changing of traffic lights 12.
In a second embodiment, the auto-navigation system 28 of vehicle 10 need only be found out the running section of vehicle, but needn't know the position of the changing of traffic lights 12 that will influence, because these changing of traffic lights 12 oneself are notified their position.Therefore new changing of traffic lights 12 can be installed, needn't upgrade described auto-navigation system with corresponding data constantly.In addition, have only if the changing of traffic lights that influences really in work, and can influence, if promptly this changing of traffic lights that will influence is launched its second information signal 31, motor vehicle module then of the present invention also just must become activation.
Also can optionally give vehicle 10 by the emitter 30 of changing of traffic lights 12 and the receiver 32 of motor vehicle module, promptly receive the first information signal 18 of vehicle 10 by acknowledgment signal of changing of traffic lights 12 transmission.If do not confirm to have received the information signal 18 that generates and send out by motor vehicle module, then can repeat to send out information signal 18 by changing of traffic lights 12.
The motor vehicle module of second embodiment also contains the memory device 34 that a control setup 20 with motor vehicle module is coupled.Depositing actual driving time in the past in this memory device 34, these running times have for example also been considered to the magnitude of traffic flow with thereby to running time influential working day, time in a few days, the traffic congestion at changing of traffic lights place and/or the traffic sign of the change on the running section for some running section.So the control setup 20 of motor vehicle module is also by considering that these actual driving times in the past obtain the running time until vehicle 10 arriving signal lamp apparatus 12 places.Additionally also can be by auto-navigation system 28 in company with counting current traffic conditions (building ground, traffic congestion or the like).By the more properly realistic in this way running time of running time that control setup 20 is obtained, the control of changing of traffic lights work of having gone forward side by side one-step optimization.
Memory device 34 also can be contained in the motor vehicle module of first embodiment of accompanying drawing 1.
