What the corresponding light handover information of the second distance-light use condition can be needed according to the second distance-light use condition Light switching mode determines.
Such as second distance-light use condition be night motor vehicle, then corresponding light handover information is uses dipped beam Lamp；
Also such as the second distance-light use condition is nighttime driving motor vehicle, and road does not have street lamp, then corresponding light Handover information is uses high beam.
Specifically it may refer to table 1.
It should be noted that table 1 is merely illustrative, as long as can determine that the condition using headlamp can serve as this Inventive embodiments the second distance-light use condition.
In force, the first distance-light use condition set and the second distance-light use condition set are independent from each other, First distance-light use condition set with the condition in the second distance-light use condition set can differ entirely, part is identical, It is all identical.
Wherein, roadside device can determine which each vehicle in coverage area currently meets by the various information of acquisition A condition.
Specifically, for any one vehicle in roadside device coverage area, the roadside device is according to second environment The car status information of part or all of vehicle in information and the coverage area received, makes from second distance-light With the second distance-light use condition for determining currently to meet in set of circumstances.
Since roadside device needs the car status information according to each vehicle in coverage area, determine that each car is current The the second distance-light use condition met, so the mobile unit of each vehicle in coverage area also needs to wirelessly The car status information of broadcast transmission oneself.
In force, mobile unit can send the vehicle-state of target vehicle (vehicle i.e. where mobile unit) with the period Information, such as 100ms are sent once；
Correspondingly, roadside device can determine that the light handover information of each vehicle in coverage area every 100ms, And it is notified by modes such as broadcast, multicast, dedicated signalings to each vehicle.
If roadside device is sent by modes such as broadcast, multicasts, the vehicle-state of each vehicle broadcast transmission oneself During information, a vehicles identifications can be carried, such roadside device can also carry pair by broadcast, multicast when modes are sent Answer the vehicles identifications of vehicle.
For example car status information A is destined to vehicle 1, then the vehicle of vehicle 1 can be carried during broadcasting van status information A Mark.
Wherein, the car status information includes part or all of in following message：
Vehicle location, car speed, vehicle acceleration, vehicle heading and vehicle head lamp state.
The second environment information includes part or all of in following message：
Location information, weather information where external brightness information, the roadside device.In force, vehicle location, vehicle Speed, vehicle acceleration, vehicle heading can be determined by modes such as GPS, mobile wireless networks.

The weather information can be determined by meteorological sensor, can also obtain vehicle present position by network Weather information determine.
Wherein, meteorological sensor includes but not limited to rain sensor, airspeedometer, fog detector, visibility detector, snow Quantity sensor etc..
Since the same weather information of day and night may also can correspond to the second different distance-light use conditions, so Weather information can also further discriminate between weather information on daytime and night weather information.
The external brightness information can be determined by optical sensor.
The position of general roadside device is changeless, so the location information where roadside device can be set in advance It puts, can also be obtained by GPS.
As shown in fig. 6, vehicle is transmitted in information schematic diagram, the vehicle-state letter of vehicle where mobile unit can broadcast oneself Breath, as long as the roadside device in broadcasting area can all receive this information
Roadside device be assured that out according to the car status information of vehicle each vehicle and other vehicles position, away from From etc., so as to be compared with the second distance-light use condition set, check which the second distance-light each vehicle meets Use condition.
In force, can be that each second distance-light use condition sets priority, in this way if for any one Vehicle finds multiple the second distance-light use conditions met, can also select highest priority according to the priority of setting One the second distance-light use condition.
If not finding the first distance-light use condition met, the headlamp state that the vehicle is current is maintained.
In force, roadside device can be according to where determining the car status information that vehicle is sent between vehicle and adjacent vehicle Adjacent vehicle distance.
Wherein it is determined that the mode of adjacent vehicle distance has very much, a kind of mode is given below：
Roadside device receives the car status information of surrounding vehicles in 100ms, and safeguards three vehicle-state chained lists：One A is uplink car status information chained list, and one is downlink car status information chained list, the last one is all vehicle-state letters Chained list is ceased, as shown in Figure 7.Each node represents the car status information of a vehicle in chained list, including position, speed, and acceleration, Travel direction, headlamp status information calculate data etc. with roadside device distance, time delay distance, are if defining up direction Positive direction, these three chained lists apart from roadside device node apart from size to sort, and the maximum node of distance is in linked list head, trackside Equipment calculates vehicle distances according to the car status information received and is inserted into the correct position of chained list, is tied in the 100ms periods Shu Hou, position of the roadside device according to vehicle in chained list calculate the distance between vehicle and opposed vehicle, and system traversal is all Car status information chained list, for example first node vehicle G is traversed, system judges that its travel direction for downlink, arrives down later Its nearest vehicle B in the same direction is found in row chained list, obtains adjacent vehicle distance in the same direction, system continues to traverse all vehicle chained lists later, The adjacent vehicle A of nearest opposite direction is found, obtains the adjacent vehicle distance of nearest opposite direction, the adjacent vehicle distance of this sample car G, which calculates, to be completed, after system Continue the adjacent vehicle distance of calculating next node vehicle A.
Roadside device is only responsible for a certain range of vehicle head lamp status information of control, if the vehicle-state received Presentation of information vehicle can then abandon this car status information except this equipment coverage area.About coverage area determine, For wireless communication system in itself there are a coverage area circle A, roadside device can receive the vehicle-state letter in the range of this Breath, but the vehicle first roadside device for being in coverage edge is perceived less than some vehicles around vehicle first, because The distance of these vehicle distances roadside devices has been more than range circle A, and roadside device is it needs to be determined that a safe distance threshold value, trackside The practical coverage area of equipment is so that the radius for justifying A is subtracted the circle B that the new radius that safe distance threshold value obtains formed.
Either bicycle pattern or trackside pattern are required for determining vehicle relative distance in many conditions, due to counting Both sides' vehicle is in high speed motions when calculating vehicle relative distance, therefore needs to consider vehicle factor during calculating relative distance The distance moved according to the time delay transmitted and calculated.In the example of aforementioned determining adjacent vehicle distance, working-flow be It is all to calculate relative distance and vehicle node is inserted into chained list according to relative distance later to receive information of vehicles, later solid Vehicle head lamp state is calculated after fixed end cycle again, for such system there are two time delay distances, first is wireless transmission The distance of time delay movement, second is from chained list is inserted into the displacement distance calculated in vehicle head lamp state this period, letter Claim arithmetic time delay distance.
Below in a manner of a kind of time delay distance is described for vehicle-mounted pattern and is estimated, this calculation needs are inserted by node The position of this vehicle and node when node is inserted into are preserved when entering chained list and is inserted into the time.Based on the considerations of secure context, system makes It needs to choose different values when correcting vehicle relative distance with the two time delay distances, it is sometimes desirable to using the time delay distance most Big value, it is sometimes desirable to using its minimum value, for example judge to need to use when whether meeting vehicle relative distance is more than secure threshold The maximum value of time delay distance needs the minimum value using time delay distance when judging meeting whether processing is over.When the two are maximum Prolong distance can all be stored in the nodal information of chained list, system-computed headlamp apart from when use.
The minimum value of two time delay distances calculates all in accordance with 0.It is wirelessly transferred the relative distance of time delay distance and two nodes There is relationship, wireless transmission time delay distance maximum value is multiplied by the maximum of setting with wireless communication system transmission limit apart from required time Speed calculating (for example the farthest communication distance between two nodes is 300m, wireless data transmission 300m needs 10us, then this Maximum value is just multiplied by the max speed of setting according to 10us).
Arithmetic time delay distance includes the displacement distance of two nodes, and the displacement distance of this vehicle can be calculated accurately, adjacent vehicle Displacement distance needs to estimate.This vehicle record when finding adjacent vehicle and adjacent vehicle node being inserted into chained list is inserted into the time, is calculating later During vehicle head lamp state according to current time subtract be inserted into the time obtain the time difference, then setting is multiplied by by this time difference The max speed obtains adjacent vehicle maximum moving distance.
Such as the situation in Fig. 8, first vehicle sends the car status information of this vehicle in position A-grade in the first class, moment A, and second vehicle is in position second A, moment B receives the vehicle amount status information of first vehicle, is wirelessly transferred time delay due to existing, first vehicle has driven in moment B Position B-grade in the first class, second vehicle obtain this truck position in moment B and calculate vehicle relative distance, this relative distance is not really opposite Distance needs to correct using wireless transmission time delay distance, and wireless transmission time delay distance maximum value is wireless communication system transmission pole Range line is multiplied by the max speed of default from required time-program(me).Second vehicle just started to calculate preceding photograph after the fixed cycle Lamp state, arrival moment C at this time, at this time first vehicle and second vehicle all have been running for a part of distance, first vehicle is in position first C, second Vehicle is in position second B.Travel distance second A can be calculated accurately because when system can preserve moment B second vehicle position second A, advance away from It can be obtained from second A by travel distance second B and travel distance second A as difference.Travel distance B-grade in the first class estimated, advance away from Maximum value calculation method from B-grade in the first class is that system saves the time of moment B, and the time difference is obtained as difference by moment C and moment B, The max speed is multiplied by with the time difference again and obtains maximum value.Relative distance is subtracted the two time delay distances by system can obtain theory Relative distance, and calculate headlamp state using this theoretical relative distance.
It is wirelessly transferred time delay distance=travel distance A-grade in the first class；
Arithmetic time delay distance=travel distance B-grade in the first class+travel distance second A；
Relative distance=position A-grade in the first class-position second A；
Theoretical relative distance=relative distance-wireless transmission time delay distance-arithmetic time delay distance；
The above is with mobile unit bicycle pattern for example, roadside device time delay distance calculation and bicycle pattern class Seemingly, details are not described herein.
