As shown in fig. 1, according to the warning method for the vehicle headlamp in the embodiment of the present application, the warning method includes:
s10: the operation information of the nearby vehicle is acquired.
That is to say, when the surrounding vehicles are in lamp communication, the operation information of the surrounding vehicles needs to be determined first, so that the state of the surrounding vehicles can be further analyzed safely, and collision between the surrounding vehicles and the own vehicle can be avoided.
The running information of the surrounding vehicle can comprise image information, adjacent vehicle speed and distance information of the surrounding vehicle, so that the current state of the surrounding vehicle can be determined through the running information of the surrounding vehicle, and further actions of the surrounding vehicle can be judged in advance, for example, whether the surrounding vehicle has operations of changing lanes, deviating lanes, decelerating, parking and the like which threaten the safety of the vehicle is judged, the problem that the surrounding vehicle collides with the vehicle is well avoided, and the driving safety is improved.
S20: and analyzing and judging the running information of the surrounding vehicles.
That is, after the operation information of the nearby vehicle is acquired, the operation information is further judged and analyzed, such as by analyzing and judging the operation information of the nearby vehicle by a control module provided for the vehicle, and specifically, the image information of the nearby vehicle may be identified and analyzed to determine whether the nearby vehicle further performs an operation, or the speed information of the nearby vehicle and the distance information from the own vehicle to determine whether there is a risk of collision between the nearby vehicle and the own vehicle.
S30: when the safety threat of the surrounding vehicles to the self vehicle is identified according to the running information, the vehicle headlights 5 are controlled to perform early warning indication, wherein the early warning indication can comprise alternate far and near light flickering, or light source emergent direction changing and light source color changing, and then the whole light is controlled to slightly turn.
That is to say, when it is determined that there is a risk of collision between the neighboring vehicle and the host vehicle, the state of the vehicle headlights 5 may be controlled, and if it is determined that there is a lane change or lane departure operation of the neighboring vehicle according to the operation information of the neighboring vehicle, the neighboring vehicle is likely to have a risk of entering the host vehicle lane abnormally, and the vehicle headlights 5 are controlled to flash alternately to indicate that the driver of the neighboring vehicle notices a vehicle traveling behind in time, so that it is beneficial to make a safe avoidance of the neighboring vehicle before the host vehicle performs a safe deceleration operation, and improve driving comfort. Wherein, controlling the vehicle headlights 5 to blink alternately may include controlling the vehicle headlights 5 to switch between high beam and low beam alternately to indicate the surrounding vehicles more prominently.
According to the early warning method for the vehicle headlights, when the safety threat of the peripheral vehicles to the vehicles per se is recognized in the running process of the vehicles, the vehicle headlights 5 can be controlled to flash to indicate that the peripheral vehicles make safe avoidance in a lamp language communication mode automatically, so that the braking and deceleration operations of the vehicles per se are reduced, and the driving comfort is improved.
In some embodiments, step S30: when the safety threat of the surrounding vehicle to the self vehicle is identified according to the operation information, the method comprises the following steps:
s31: and judging whether the peripheral vehicle has lane departure or lane change according to the running information of the peripheral vehicle. It is understood that, during the running of the vehicle, when the surrounding vehicle suddenly performs a lane-departure or lane-change operation, it is extremely easy to cause an accidental collision between the surrounding vehicle and the own vehicle, and thus, determining whether the surrounding vehicle has the lane-departure or lane-change condition can effectively avoid the risk of a safe collision between the surrounding vehicle and the own vehicle.
Further, S32: if the lane departure or lane change exists, the surrounding vehicle is judged to have safety threat to the vehicle, namely when the surrounding vehicle is determined to perform lane change or lane departure operation, the headlights of the vehicle are controlled to flash, and the surrounding vehicle is safely shown.
In some embodiments, the operation information of the nearby vehicle includes image information, step S31: judging whether the peripheral vehicle has lane departure or lane change according to the running information comprises the following steps:
s311: and if the situation that the surrounding vehicle has a pressure line or a steering lamp close to the side of the vehicle lane is turned on is detected according to the image information, judging that the lane is deviated or changed.
The front cameras are arranged in front of and at the front side of the vehicle, and can continuously shoot and acquire pictures in the visual fields at the front and the front side of the vehicle, so that the front cameras can acquire image information of the peripheral vehicle, wherein the front cameras can shoot the motion track of the peripheral vehicle and the positions of various components of the vehicle on a lane, such as whether wheels of the peripheral vehicle press or cross a lane line, or shoot component schematic actions of the vehicle, such as shooting turn lights of the peripheral vehicle to flash, so as to determine the operation intention and the motion state of the peripheral vehicle.
Therefore, the operation intention of the surrounding vehicles is judged by detecting the states of the wheels and the steering lamps of the vehicles through the front camera, if the surrounding vehicles press a lane line, the fact that the surrounding vehicles have the risk of deviating from lanes of the surrounding vehicles to enter the lane of the vehicles is determined, or the fact that the surrounding vehicles turn left to enter the lane of the vehicles is determined when the left steering lamps of the surrounding vehicles on the right turn to flicker, therefore, the headlights 5 of the vehicles are controlled to flicker alternately to safely indicate the surrounding vehicles in time, drivers of the surrounding vehicles can avoid safely in time, and driving safety is improved. Note that the nearby vehicle in which the deviated vehicle or lane change occurs is a vehicle adjacent to the nearby vehicle.
In some embodiments, the operation information of the nearby vehicle includes distance information of the nearby vehicle from the own vehicle, and speed information of the nearby vehicle, and the warning method further includes:
s40: the vehicle speed of the vehicle is acquired.
That is, when the vehicle headlight 5 is operated for early warning, the running speed of the vehicle can be detected and acquired, so that the running state of the surrounding vehicle and the running state of the vehicle can be integrated, and the vehicle can be safely controlled, thereby more accurately and effectively avoiding the collision between the surrounding vehicle and the vehicle.
In which a vehicle speed sensor may be mounted on a vehicle to acquire a running speed of the vehicle in real time through the vehicle speed sensor.
S41: and judging whether the peripheral vehicle has the risk of collision with the self vehicle according to the distance information between the peripheral vehicle and the self vehicle, the speed information of the peripheral vehicle and the speed of the self vehicle. And if the surrounding vehicle has the risk of collision with the own vehicle, determining that the surrounding vehicle has a safety threat to the own vehicle. The peripheral vehicle is a vehicle on the same lane, namely a vehicle ahead of the vehicle.
That is to say, when it is judged that the front vehicle has a risk of collision with the self vehicle according to the distance information between the front vehicle and the self vehicle, the speed information of the front vehicle and the self vehicle speed, it is determined that the front vehicle has a safety threat to the self vehicle, and at this time, the vehicle headlights 5 are controlled to give an early warning, for example, the vehicle headlights 5 are controlled to alternately flash to indicate that the front vehicle is safely avoided. That is to say, the predicted cut-in trajectory of the front vehicle can lead to the deceleration of the self-adaptive cruise system, and then the system is considered to have a certain collision risk, and at the moment, the system can send out a flashing light instruction at a corresponding time point before the deceleration instruction is sent out according to the speed difference of the two vehicles to prompt the rear of the front vehicle to come, so that the self-vehicle is prevented from carrying out deceleration operation, and the driving comfort is improved.
In some embodiments, step S41: the judging whether the peripheral vehicle has the risk of collision with the own vehicle according to the distance information between the peripheral vehicle and the own vehicle, the speed information of the peripheral vehicle and the speed of the own vehicle comprises the following steps:
s411: acquiring the pre-judgment running time of the vehicle contacting the peripheral vehicle according to the distance information between the peripheral vehicle and the vehicle, the speed information of the peripheral vehicle and the speed of the vehicle; and if the pre-judged running time is less than the first set time value, the surrounding vehicle has the risk of colliding with the vehicle.
Wherein, the installation vehicle can detect and acquire the distance information of the place ahead vehicle and self vehicle, the speed information of place ahead vehicle in the front camera of place ahead and front side, from this, through the distance information of detecting place ahead vehicle and self vehicle, the speed information of place ahead vehicle, carry out the warning of the automatic flashing light in turn of distance light dipped in the future and steerable speed of a motor vehicle guarantees driving safety, great promotion the travelling comfort of intelligent driving function, it is simple to realize, the cost is lower.
It should be noted that after the distance information between the front vehicle and the self vehicle, the speed information of the front vehicle, and the self vehicle speed are acquired, the time for the front vehicle to contact with the front vehicle after the front vehicle and the self vehicle continue to travel at the current speed can be calculated by the control module, and it can be understood that if the traveling speed of the front vehicle is greater than the traveling speed of the self vehicle, the self vehicle cannot contact with the peripheral vehicle, and when the traveling speed of the front vehicle is less than the traveling speed of the self vehicle and the risk of the self vehicle colliding with the front vehicle exists in a short time, the front vehicle is early-warned by the vehicle headlight 5. The first set time value can be flexibly selected according to the actual braking performance of the vehicle, for example, the first set time value is 15s, 18s or other time ranges.
S412: the early warning method further comprises the following steps: if the pre-judged running time is less than a second set time value, controlling the electro-hydraulic braking module to brake the vehicle; the second set time value is smaller than the first set time value, for example, the second set time value is 12s, 13 s.
That is to say, when the time that the front vehicle and the self vehicle continuously keep moving at the current speed and the self vehicle contact the front vehicle is too short through the control module, the driver of the front vehicle cannot avoid the self vehicle in time, the self vehicle is braked through the electro-hydraulic brake module, so that the self vehicle is braked and decelerated, specifically, if the wheels of the vehicle are braked through an electro-hydraulic brake control system or a force transmission piece on a power transmission system is braked and controlled, the deceleration effect of the self vehicle is realized, and the driving safety is ensured.
The early warning method further comprises the following steps: when the vehicle headlight 5 is controlled to give an early warning indication, the command for controlling the vehicle headlight 5 is shared in the vehicle-mounted network. Therefore, the safety indication of the whole vehicle control system to a driver is facilitated, or the braking system is automatically controlled to brake and decelerate the vehicle, so that the driving safety is ensured.
The early warning method of the vehicle headlamp of the embodiment of the application carries out far-beam and near-beam automatic alternate flashing warning and can control the vehicle speed to guarantee the driving safety by detecting the speed of the adjacent vehicle, the distance information and the own vehicle information, the comfort of the intelligent driving function is greatly improved, the realization is simple, and the cost is lower.
