To make the purpose, technical scheme and advantage of the embodiment of the present invention clearer, below in conjunction with this hair
Accompanying drawing in bright embodiment, is clearly and completely described to the technical scheme in the embodiment of the present invention,
Obviously, described embodiment is a part of embodiment of the invention, rather than whole embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained under the premise of creative work is not made
The all other embodiment for obtaining, belongs to the scope of protection of the invention.
Car light is the basic configuration of automobile, for providing illumination when light is bad for vehicle.Car light is divided into
High beam and dipped headlight, wherein dipped headlight irradiation distance are short, and light gathering degree cannot be adjusted；High beam light collection
In, brightness is larger, and irradiation distance is remote.Fig. 1 is the car light irradiation scope schematic diagram of automobile, such as Fig. 1 institutes
Show, for vehicle 11, the range of exposures of dipped headlight is scope 12, and the range of exposures of high beam is scope
13.Meanwhile, dipped headlight irradiating angle in vertical direction is relatively low, and high beam is in vertical direction
Irradiation is relatively low higher.Therefore influence of the high beam to other vehicle drivers is larger.
Fig. 2 be car light usage scenario schematic diagram, as shown in Fig. 2 have on road vehicle 21, vehicle 22,
Vehicle 23 and vehicle 24 totally four automobiles.Vehicle is travelled on road and is required in fixed track,
And Ordinary Rd is all two way, there are two travel directions.Wherein vehicle 21 and the row of vehicle 22
Sail direction identical, vehicle 23 is identical with the travel direction of vehicle 24.
For vehicle 21, because vehicle 22 and vehicle 22 are in same track, and positioned at vehicle 21
Front, then if vehicle 21 opens car light, the driver of vehicle 22 from the rearview mirror of vehicle 22 will etc.
Enough it was observed that the car light of vehicle 21.But if vehicle 21 is relatively near apart from vehicle 22, and vehicle 21
Open high beam, then because the irradiating angle of high beam is higher, brightness is larger, light is concentrated, car
22 driver will intelligently see the white light that light reflection goes out from rearview mirror, and after car cannot being observed
Other situations.
Vehicle 21 and the Facing Movement of vehicle 23, and vehicle 23 and vehicle 21 are located at adjacent track.
If vehicle 21 opens car light under steam, then the driver of vehicle 23 is possible to observe vehicle 21
Car light.If vehicle 21 opens high beam, and vehicle 21 is closer to the distance with vehicle 23, then
Because the irradiating angle of high beam is higher, the high beam of vehicle 21 by direct irradiation vehicle 23 driving
Room, this will have a strong impact on the sight line of the driver of vehicle 23, in some instances it may even be possible to make driver's wink of vehicle 23
Between blinding.
Vehicle 21 and the Facing Movement of vehicle 24, two tracks of vehicle 21 and 24 midfeather of vehicle, that
If vehicle 21 opens car light, vehicle 24 will not be in the range of the car light irradiation of vehicle 21.Now
Even if vehicle 21 opens high beam, then also will not produce influence to the driver of vehicle 24.
In order to ensure the driving safety of vehicle, it is desirable to be able to which dipped headlight and high beam to vehicle are carried out automatically
Control.There are dipped beam and the scheme of distance light automatic switchover in vehicle at present, but it is all mainly right by detecting
Switched over to the light of vehicle, reach certain threshold value when opponent vehicle lamplight brightness is detected, then
Car light is actively switched into dipped beam.But the application scenarios of this scheme are restricted, such as opposed vehicle does not have
Turn on light, or during car light failure, will be unable to use, and influence is likely under harsh weather
Judgement to opposed vehicle light.In addition, during such scheme cannot also realize vehicle travel process in the same direction
Dipped beam and distance light automatically switch.
With the development of technology of Internet of things, car networking technology is gradually applied in vehicle.Wherein car car
Communication (Vehicle-to-Vehicle, V2V) is a kind of communication mode in car networking technology.Truck traffic
Refer to that can carry out mutual communication between vehicle.So in the embodiment of the present invention, it is considered to use Che Chetong
The mode of letter, is automatically switched by the data interaction between vehicle come the dipped headlight and high beam to vehicle.
The nearly distance light automatic switching method that Fig. 3 is provided for one embodiment of the invention, as shown in figure 3, this reality
The nearly distance light automatic switching method for applying example offer includes：
Step S301, at least two second vehicle location signals that first the second vehicle of vehicle receiver sends.
Specifically, in car networking technology, can be in communication with each other between vehicle, wherein, vehicle it
Between communication can use any one possible communication mode, such as DSRC (Dedicated
Short Range Communications, DSRC) etc..But the communication between vehicle typically has certain
Distance limitation, only within the communication distance of the communication mode for being used, can just carry out phase between vehicle
Mutual communication.Communication between vehicle can be it is two-way can also be it is unidirectional, in the present embodiment, only
Want the ability for possessing one-way communication between vehicle.When the communication between vehicle is one-way communication, by
The interaction of row information is not entered between vehicle, in order to ensure that the information that vehicle sends can be by other vehicles
Receive, usually, vehicle is all to send information in a broadcast manner according to some cycles.
The first vehicle travelled on road can receive the positional information that the vehicle in certain distance sends,
If the vehicle that positional information is sent to the first vehicle is the second vehicle, the second vehicle will be broadcasted with some cycles
The position signalling of the second vehicle.Adopted when the distance between the first vehicle and the second vehicle reach both communications
When in the communication distance of communication mode, the first vehicle is possible to receive the periodically transmission of the second vehicle
The second vehicle location signal.Can include that the geographical position of the second vehicle is believed in second vehicle location signal
Breath, then after the first vehicle receiver is to the signal, you can determine the particular location of the second vehicle.Second
Vehicle location signal without the geographical location information of the second vehicle, but can also be worked as the first vehicle receiver and arrive
After at least two second vehicle location signals, according to two received signals, gone with certain algorithm
Calculate the particular location of the second vehicle.
Step S302, the first vehicle determines the position of the second vehicle according at least two second vehicle location signals
Put.
Specifically, if there is no the more specific location information of the second vehicle in the second vehicle location signal, then the
One vehicle is accomplished by being gone to determine the position of the second vehicle according at least two vehicle location signals for receiving.
Second vehicle sends the position signalling of the second vehicle according to some cycles, if the first vehicle and second
Vehicle all remains stationaries, then the first vehicle also will receive the position signalling of the second vehicle with the cycle.But
In transport condition when vehicle is on road, then at least two second vehicles that the first vehicle receiver is arrived
Position signalling time difference will from the second vehicle send the second vehicle location signal cycle it is different.First,
If the time difference is more than the cycle, mean that the distance of the first vehicle and the second vehicle is more and more remote, if
The time difference is less than the cycle, then mean that the distance of the first vehicle and the second vehicle is more and more nearer.Secondly,
Because the first vehicle and the second vehicle are all in motion state, the position of the second vehicle that the first vehicle receiver is arrived
Confidence number will produce frequency displacement due to Doppler effect, and the size and the first vehicle according to Doppler frequency shift are certainly
The speed of body, it may be determined that the speed of the second vehicle.Further, according at least two second cars for receiving
Position signalling direction change, it may be determined that the direction of motion of the second vehicle.Amid all these factors,
Can determine that the relative position relation of the first vehicle and the second vehicle.In fact, the side for passing through truck traffic
Formula determines that the relative position relation between vehicle is that those skilled in the art can be by existing theoretical foundation
Mathematical Modeling and draw, be only in the present embodiment schematically to illustrate.
Step S303, the first vehicle determines whether the second vehicle is located at the first car according to the position of the second vehicle
In high beam coverage.
Specifically, because the car light coverage of vehicle is after vehicle production is good, you can it is determined that, can recognize
To be a fixed value.So when the first vehicle determines the relative position of the second vehicle and the first vehicle
Relation, you can determine whether the second vehicle is located in the car light coverage of the first vehicle, more specifically,
Can determine whether the second vehicle is located in the high beam coverage of the first vehicle.First vehicle and second
Vehicle is in real-time motion state, therefore the first vehicle needs to implement to judge whether the second vehicle is in
In the coverage of the high beam of the first vehicle.
Step S304, if the second vehicle is located in the first vehicular high beam lamp coverage, and the first vehicle
High beam is in opening, then high beam is switched to dipped headlight by the first vehicle.
Specifically, if the second vehicle is in the coverage of the first vehicle, in order to avoid the first vehicle
High beam influences on the driver of the second vehicle, if the high beam of the first vehicle is in opening,
So high beam can be switched to dipped headlight by the first vehicle, so as to avoid high beam from driving the second vehicle
The person of sailing produces influence, it is ensured that vehicle driving safety.Certainly, if the high beam of the first vehicle is not in opening
State, that without switching over again.
The nearly distance light automatic switching method that the present embodiment is provided, is sent by first the second vehicle of vehicle receiver
The second vehicle location signal, determine the second vehicle whether be located at the first vehicular high beam lamp coverage in,
If the second vehicle is located in the first vehicular high beam lamp coverage, and the high beam of the first vehicle is in unlatching
State, then the first vehicle high beam is switched into dipped headlight, so as to avoid the high beam of the first vehicle to
The driver of two vehicles produces influence, it is ensured that vehicle driving safety.
The nearly distance light automatic switching method that Fig. 4 is provided for another embodiment of the present invention, as shown in figure 4, this
The nearly distance light automatic switching method that embodiment is provided also includes on the basis of Fig. 3：
Step S401, if the second vehicle leaves the coverage of the first vehicular high beam lamp, and the first vehicle is remote
There is no other vehicles in light lamp coverage, then dipped headlight is switched to high beam by the first vehicle.
Specifically, in the present embodiment, step S301 is identical with embodiment illustrated in fig. 3 to step S304.
After step S304, after high beam is switched to dipped headlight by the first vehicle, the first vehicle continues to second
The position of vehicle is detected, if the second vehicle leaves the coverage of the first vehicular high beam lamp, then the
Car light may be reverted to high beam state before the handover by one vehicle.But before the handover, the first vehicle is also
Need whether also there are other vehicles in the high beam coverage for consider the first vehicle, if the first vehicle
High beam coverage in also without other vehicles exist, then the first vehicle can switch dipped headlight
To high beam state.
The meaning of this step is that it is because the first vehicle is worked as that the driver of the first vehicle opens high beam
The road conditions of preceding traveling are adapted for use with high beam.If therefore according to the method for embodiment illustrated in fig. 3 by distance light
Lamp switches to dipped headlight, when the second vehicle leaves the high beam coverage of the first vehicle, if the first car
Still travelled with dipped headlight state, the driver of the first vehicle may be made not see road conditions, therefore,
In order to ensure the normally travel of the first vehicle, when the second vehicle leaves the high beam coverage of the first vehicle
When, and also exist without other vehicles in the high beam coverage of the first vehicle, the first vehicle can be with
Dipped headlight is switched into high beam again.
All it is, using the first vehicle as signal receiving end, to receive second in Fig. 3 and embodiment illustrated in fig. 4
The second vehicle location signal that vehicle sends.But in order that other vehicles are also able to detect that the first vehicle
In the presence of the first vehicle similarly can periodically send the first vehicle location signal.First vehicle location
Signal is used to make the vehicle for receiving the first vehicle location signal determine the position of the first vehicle.
Further, in Fig. 3 or embodiment illustrated in fig. 4, it is proposed that can be according to the relative position of vehicle
Relation carries out the switching of high beam and dipped headlight.But nearly distance light automatic switchover side provided in an embodiment of the present invention
Method can also be in other cases to vehicle car light be controlled, so as to realize the full-automatic of lights of vehicle
Control.
The car light of vehicle is typically all or the haze sky when night, traveling are in the medium dark in tunnel
Etc. bad weather when need open, wherein dipped headlight is used when speed is relatively low, high beam be
Used when speed is higher.So the first vehicle just can be according to the bright and dark light degree and first outside car
The speed of vehicle is automatically controlled to car light.When the bright and dark light degree outside the first vehicle car is less than default
Threshold value, then the first vehicle determine need open car light, now the first vehicle determine present speed again, if
Present speed is less than predetermined threshold value, then the first vehicle determines to open dipped headlight, if present speed is more than default
High beam is opened in threshold value, then the first vehicle determination.On this basis, in conjunction with described in Fig. 3 or Fig. 4
Nearly distance light automatic switching method, you can realize the Automatic Control of vehicle car light.
It can be seen from the car light usage scenario shown in Fig. 2, the relative position relation between vehicle is divided into various
Situation, still by taking scene shown in Fig. 2 as an example, to nearly distance light automatic switching method provided in an embodiment of the present invention
Specifically used scene illustrate.
In fig. 2, if vehicle 21 is the first vehicle, when vehicle 22 is the second vehicle, if the He of vehicle 22
When the distance between vehicle 21 is in default communication distance, vehicle 21 will receive what vehicle 22 sent
The position signalling of vehicle 22.Vehicle 21 determines vehicle 22 according to the position signalling of the vehicle 22 for receiving
Position, when it is determined that vehicle 22 and vehicle 21 are located at same track and travel in the same direction, vehicle 21 enters one
Step ground determines whether vehicle 22 is located in the high beam coverage of vehicle 21.If the speed of vehicle 21 is big
In the speed of vehicle 22, then the distance between vehicle 21 and vehicle 22 will be approached constantly, at certain for the moment
Between put vehicle 22 will necessarily enter vehicle 21 high beam coverage, now vehicle 21 can be by distance light
Lamp switches to dipped headlight.Due to the speed of the speed more than vehicle 22 of vehicle 21, then vehicle 21 may
Vehicle 22 is overtaken other vehicles, when vehicle 21 exceedes vehicle 22, because vehicle 22 has been positioned at car
21 rears, then inevitable not in the high beam coverage of vehicle 21, now vehicle 21 is detected
When in high beam coverage without other vehicles, then dipped headlight is switched into high beam.
If vehicle 21 is the first vehicle, when vehicle 23 is the second vehicle, if vehicle 23 and vehicle 21 it
Between distance in default communication distance when, vehicle 21 will receive the vehicle 23 that vehicle 23 sends
Position signalling.Vehicle 21 determines the position of vehicle 23 according to the position signalling of the vehicle 23 for receiving, when
When determining that vehicle 23 is located at adjacent lane and travels in opposite directions with vehicle 21, vehicle 21 further determines car
Whether 23 be located in the high beam coverage of vehicle 21.Due to vehicle 21 and the opposite row of vehicle 23
Sail, then inevitable when sometime putting, vehicle 23 will enter the high beam coverage of vehicle 21,
Now high beam can be switched to dipped headlight by vehicle 21.Meeting is completed Deng vehicle 21 and vehicle 23, that
Vehicle 23 will be positioned at the rear of vehicle 21, then inevitable not in the high beam coverage of vehicle 21,
When now vehicle 21 is detected in high beam coverage without other vehicles, then dipped headlight is switched into distance light
Lamp.
Further, in the various embodiments described above, be with the dipped headlight of vehicle and high beam coverage all
It is fixed, the cab position of vehicle is also the explanation carried out as a example by giving tacit consent to.But in fact, due to
Vehicle manufacturers are numerous, and vehicle model is also numerous, the high beam coverage of each vehicle be it is different,
The cab position of each vehicle is also different.For example for load truck and family-sized car, it is subject to far
The influence of light lamp is completely different.Therefore, in the nearly distance light automatic switching method shown in Fig. 3 or Fig. 4
On the basis of, following method can also be included：Wrapped in the second vehicle location signal of the first vehicle receiver
Include the vehicle information of the second vehicle.First vehicle it is determined that behind the position of the second vehicle, according to the second car
Position determine whether the second vehicle is located at when in the high beam coverage of the first vehicle, herein in connection with the
The vehicle information of two vehicles.That is, simultaneously not only considering whether the second vehicle is located at the remote of the first vehicle
In light lamp coverage, but the high beam whether driver's cabin of the second vehicle of consideration is located at the first vehicle covers
Lid scope.In other words, as according to the different automobile types of the second vehicle, judging the high beam of the first vehicle
Whether influence can be produced on the driver in the driver's cabin of the second vehicle.Only when the high beam of the first vehicle
When can be rung to the heavy sound shadow of driver in the driver's cabin of the second vehicle, just the high beam of the first vehicle is switched
To dipped headlight.Dipped headlight and high beam that so both can be more accurately to vehicle carry out auto-changeover control.
