Therefore according to an embodiment, in vehicle 110,130, realize prospective light to car communication system or car to infrastructure-based communication system by car in this mode proposed and regulate.At this, can be considered as in a target of this mode proposed, the light device (it also can synonymously be called lighting apparatus 115) of vehicle 100 automatically switches to the pattern of needs to car communication system and/or car to infrastructure-based communication system 132,120,110 by car, and therefore minimizes the risk of self harm that the lighting apparatus 115 that regulated by mistake is caused, in road traffic and other danger.If weather conditions, daylight hours or vehicle-periphery requirement, then the headlight of light device 115 can be connected exactly all the time or switch.At this, such as, also self light can be regulated and send to surrounding vehicles with the information of spaces of vehicles or be sent in surrounding vehicles (car communicates to car) and there for regulating the light device of surrounding vehicles 130.In addition, light regulates the following feedback that the transmission (car is to infrastructure-based communication) of data 135 infrastructure towards periphery can obtain from infrastructure with this object: whether self the light setting of weather conditions, daylight hours or surrounding environment aspect is correct.According to the feedback from infrastructure, can change or keep the light in vehicle 100 to regulate.Transmission and the reception of significant data realize by least one wireless connections.In addition, can receive in vehicle and the information that process is important further there, such as weather conditions, daylight hours, spaces of vehicles and the light adjustment of other vehicle participant and the light adjustment of surrounding infrastructure, its target is optimally and automatically controls self light device 115.
Therefore, be in of this mode proposed is interested especially, the car existed in the near future to car communication or car to infrastructure-based communication for make light device in vehicle and such as weather conditions, daylight hours, surrounding environment and with surrounding vehicles Optimum Matching.At this, target regulates minimizing of self harm that causes and other harm by the mistake of the vehicle light device in road traffic.In the load shedding that the essential advantage of this mode proposed is vehicle driver, because automatically carry out each light adjustment.At this, the mistake can getting rid of the light device of vehicle as well as possible regulates.
Thus, such as by each vehicle participant automatically and do not need to meet the requirement in the light adjustment of road traffic regulation in vehicle with self assisting, described vehicle participant carry this propose for controlling the device of the lighting apparatus in vehicle and receiving corresponding signal of communication.At this, the traveling in weather conditions in dark surrounding environment and difficult is made to become simpler and become safer for all vehicle participants.
When there are self harm scene following and other harm scenes in addition, it is especially debatable that the wrong light in vehicle regulates, and more to elaborate below this:
1., when night, two vehicles are close to each other in the opposite direction.A mistake in vehicle switches its light lately and regulates or be switched to " dipped beam " from " distance light " at all.Thus, dazzlingly head-on sail relative to it vehicle of coming and this is had an accident, because identified the vehicle head-on sailing by trend of road dazzling not correct in the worst situation.
2., when night, traffic participant forgets the light device of its vehicle of connection and other the enough illuminations by means of street lamp in urban transportation travel.During it also travels in city, described behavior causes harm.Late ground or basic not identified and have an accident in the worst situation crossed by its vehicle.If described traffic participant sails out of thrown light on urban parts, then it travels suddenly and no longer identifies trend of road in complete darkness.According to speed and trend of road, also may have an accident at this.
3. thick fog shrouds.The traffic participant in vehicle with operational " mist light " is forgotten or ignores connection described " mist light ".Its vehicle by subsequently and head-on sail the vehicle come and cross late identifying.There is rear-end collision (Auffahrunfall) or when vehicle is head-on sailed, frontal collisions occur in this.
4. the vehicle with " the mist light " connected sails out of mist.Described " mist light " keeps connecting.Subsequently or head-on sail come traffic participant dazzling.Had an accident by the dazzling of other traffic participants.
5. vehicle travels in the roads and tunnels of only intense illumination.Driver forgets the light device of connecting vehicle or excessively late connects described light device.On the one hand, described vehicle is crossed and is identified by other traffic participant lately.On the other hand, driver no longer clearly can identify trend of road.In the worst situation, had an accident by self harm or other harm.
Be in an importance of this mode proposed, minimize and regulate by the wrong light in vehicle self harm and other harm that cause.This can be regulated by the automatic light in vehicle and realize, as it is described in detail in one embodiment.
Car is to car communication system
According to the car of the first embodiment in car communication system, realize under the vehicle lower than certain minimum spacing light regulate equilibrium.Head-on sail come vehicle in or in the vehicle in succession travelled, described minimum spacing can be different, generation emergency situation from described minimum spacing.
Fig. 3 illustrates the diagram of a harm scene.In described harm scene, vehicle 100 drives towards first other vehicles 130 with spacing A and follows another other vehicles 300 with spacing B simultaneously and travels.In the further process described, part because the reason of simplified characterization is only by reference marker differentiation vehicle, but wherein represents vehicle 100, other vehicles 130 or another other vehicles 300 according to used reference marker.Can be identified by Fig. 3, the minimum spacing A of vehicle 130 or 300 is different with B, carrying out automatic light adjustment at the car with above proposed device 110 (it illustrates in figure 3 no longer clearly) lower than during described minimum spacing in car communication system.
Vehicle 100 moves with identical direction (see arrow 315) on road 310 with 300.Meanwhile, in reverse traffic, other vehicles 130 are close.The automatic light occurred in from minimum spacing B for the vehicle 100 and 300 in succession travelled described in this mode proposed regulates.The minimum spacing B between vehicle 100 and 300 is almost reached in described example.Now, between vehicle 100 and 300, also automatic light adjustment is not carried out.Other vehicles 130 have not only vehicle 100 but also another other vehicles 300 in its reverse traffic.Other vehicles 300 are lower than minimum spacing A, but vehicle 100 is not also lower than described minimum spacing.Vehicle 300 and 130 advantageously has its light coordinated with each other from minimum spacing A respectively and regulates, the behavior that such as basis has described in fig 1 and 2 is when using two-way communication signals for being transferred to another other vehicles 300 by information from (first) other vehicles 130, and vice versa.In this example, the switching from " distance light " to " dipped beam " is adopted when not limiting generality.For this reason, except each lighting apparatus 115 of the diagram corresponding to Fig. 1, vehicle 100,300 and 130 advantageously also has each device 100 and receiving element 120, so that can the signal of communication 125 that receives of analyzing and processing and correspondingly can control the running status of lighting apparatus 115.Additionally, the vehicle 100,300 and 130 of Fig. 3 also can have the unit 135,148 and 132 corresponding to the diagram of Fig. 1 respectively, so as also can to other vehicle the corresponding corresponding self-operating state notifying the lighting apparatus 115 of described vehicle or the lighting apparatus 115 that can detect other vehicle running status and corresponding control signal can be exported.
By Fig. 3 described above, the automatic light described in detail in vehicle 100,300 and 130 by minimum spacing A and B according to harm scene now regulates.Harm scene 1
In order to the harm minimized in harm scene 1 (head-on sail when night come vehicle by " distance light ") is potential, the switching from " distance light " to " dipped beam " in all vehicles of moving in the opposite direction (at this i.e. vehicle 100 and 130), should be realized from minimum spacing A.When using glossary, i.e. ABL

Car is to infrastructure-based communication system
According at the car of another embodiment of this mode proposed in infrastructure-based communication system, as long as lower than certain minimum spacing, the light just carrying out vehicle regulates and surrounding environment balanced.
Fig. 4 illustrates another harm scene.At this, minimum spacing C and the surrounding environment of vehicle 100 and 300 is graphically shown, carrying out light adjustment lower than during described minimum spacing.At this, the minimum spacing C (example at this traffic tunnel) regulated to the automatic light in infrastructure-based communication system for car shown in Figure 4.
Vehicle 100 travels with identical direction (see arrow 315) with 300 and is about to travel on tunnel 400 on road 310.Meanwhile, in reverse traffic, from tunnel 400, the vehicle 130 come is sailed close.In described harm scene, the automatic light carrying out describing in embodiment described herein from the minimum spacing C of the transmitter unit and/or receiving element 410 (car is to infrastructure transmitter unit) with surrounding environment regulates, described transmitter unit and/or receiving element are set to a part for traffic infrastructure (in this tunnel 400) and launch signal of communication 125, wherein comprise pitch information (such as positional information or as following information: signal propagation time can be asked for by described information and ask for spacing by described signal propagation time) on the one hand, described pitch information can realize the determination of the spacing of the vehicle 100 or 300 receiving described signal of communication 125.In addition, in signal of communication 125, also can comprise the information of the running status gone code or about the lighting apparatus of vehicle 100 or another other vehicles 300, it gives related device 110 in corresponding vehicle 100 or 300 about connection dipped beam to cross the instruction in tunnel 400.In this example, reach minimum spacing C by vehicle 300 and 130, and also do not reach minimum spacing C by vehicle 100.Therefore, the light of vehicle 100 regulates the impact not also being subject to surrounding environment or traffic infrastructure.As long as vehicle 300 is lower than minimum spacing C, if described light device still cuts off, just realize light device in described vehicle 300 with the connection of " dipped beam " pattern.Therefore, vehicle 300 travels on shown tunnel 400 by (closely) light connected.On the other hand, the light also affecting vehicle 130 before it sails out of minimum spacing C regulates, and its mode is, is cut off the light of vehicle 130 by the instruction of infrastructure 400 or corresponding launching and receiving unit 410.But, realize the described cut-out of the light device of vehicle 130 time only by day.
Therefore, the automatic light further described in vehicle 100,300 and 130 by minimum spacing C according to harm scene now by the diagram of Fig. 4 regulates.
Harm scene 5
In order to minimize harm potential 5 (not travelling on poor the tunnel 400 thrown light on having light time by day), should realize the connection of light device 115 in all vehicles 100,300 or 130, described all vehicles travelled on tunnel 400 before sailing minimum spacing C into:

For the correct connection of light device and cut-out, the understanding of the travel direction of involved vehicle 100,300 or 130 is important.In this example importantly, vehicle 100,300 or 130 travels on or just sails out of tunnel 400.Information about travel direction such as can be calculated from the signal propagation time of the signal of communication 125 launched by launching and receiving unit 410 or from the propagation time of the signal of communication 125 (as car to car signal of communication) between vehicle or be determined by radar system, camera chain and gps system.Danger in harm scene 5 is minimized by the correct connection of the light device 115 in vehicle 100,300 or 130 or cut-out.
For the vehicle with electric driver, automatic light regulates and also provide other advantage except secure context.An essential advantage is, the light by foresight regulates saves valuable battery current.At this, it is contemplated that following scene:
As long as-lower than the minimum spacing of the vehicle with traveling ahead, the luminous intensity of its headlight is just reduced in required minimum value by the motor vehicle in succession travelled.Do not have other vehicle motor vehicle travelled within minimum spacing to continue to run its light device with normal (" dipped beam ") in its front.
The luminous intensity of its headlight is mated with surrounding environment by-motor vehicle.If motor vehicle is arranged in the urban parts of good illumination, then the luminous intensity of headlight is reduced in required minimum value.In dark surrounding environment, also continue to use completely " dipped beam ".
Information about surrounding environment illumination can be arrived in vehicle by different modes.At this it is envisaged that such as car is to the light-sensitive sensors in infrastructure-based communication or vehicle.
In the autonomous vehicle travelled, be probably desirably in the use of the mode that this proposes.In the near future, vehicle will completely independently move.In this scene, occupant such as engages in the thing different from the guiding of vehicle on back seat.In this case, because vehicle autokinetic movement, so automotive occupant can not be concerned about that the light in its vehicle regulates again.Therefore, in autonomous vehicle, prospective light regulates is very important.
In addition, in autonomous vehicle, also obtain another advantage following: in order to save gasoline or energy, autonomous vehicle in the future probably so-called have in the vehicle platoon of very little spacing between vehicle move.In this vehicle platoon, as long as lower than the minimum spacing with the vehicle of the traveling ahead in queue, just the luminous intensity of headlight can be reduced in minimum value.This is especially favourable in motor vehicle.But first in vehicle platoon (forefront) vehicle keeps the luminous intensity completely of headlight.
For realize the most important precondition of the Part I (car is to car communication) of the mode proposed at this be in vehicle car to the existence of car communication system.For the several years subsequently, not only OEM but also supplier clarify a plan for these.For the Part II (car is to infrastructure-based communication) of the mode proposed at this, not only in vehicle but also in important surrounding environment, car is necessary to the existence of infrastructure-based communication system.
In addition, in order to the realization completely of mode proposed at this, daylight hours and weather conditions are conclusive by the understanding of described communication system.As long as important vehicle is arranged in a minimum spacing, described information just or by surrounding environment (car is to infrastructure) arrives in described important vehicle.In addition it is envisaged that the reception of gps system, radio system or mobile telephone system is passed through in daylight hours and weather conditions.
Another part of can not ignore of this mode proposed be vehicle each other or the understanding of spacing with the infrastructure of surrounding.Only so, can determine light regulate minimum spacing lower than or exceed.Directly can determine required spacing to car communication system or car to the propagation time of (communication) signal in infrastructure-based communication system by car.Other possibilities that spacing is determined are radar system, camera chain or gps system in vehicle self.
As long as there is corresponding infrastructure, just very likely realize the present invention (time span < 10 years) in the near future.
