Glare is one of the major factors affecting the health of the light environment. Although the human eye can adapt to brightness in the range of about 14 orders of magnitude, when a certain field of view brightness level is adapted over a period of time, the effective area of brightness that can be adapted will be reduced to 4 to 5 orders of magnitude, and other objects or light sources above that area will produce glare. If the luminous intensity of the vehicle lamplight is too high, uncomfortable feeling can be caused to other road users, and psychological discomfort and visual fatigue can be caused by the glare effect, so that physiological discomfort phenomena such as dysphoria, inattention and the like are caused.

After the lamplight starting instruction, the vehicle state information, the environment brightness information and the vehicle distance information are acquired, the whole vehicle controller comprehensively judges which car lamp is started and how to regulate the luminous intensity of the car lamp according to the acquired various information, so that the luminous intensity of the car lamp is not uncomfortable to a driver of a rear vehicle, and traffic accidents caused by the fact that the driver of the rear vehicle is too strong in glare are avoided.

According to the vehicle lamp control method, under the condition that the light starting instruction is received, the vehicle state information, the environment brightness information and the vehicle distance information of the vehicle are obtained, the luminous intensity of the rear lamp of the vehicle is comprehensively adjusted according to the environment brightness information and the vehicle distance information when the vehicle is in different driving states, so that the luminous intensity of the rear lamp can be adjusted according to the distance between the vehicle and the rear vehicle and the environment brightness when the vehicle is in different driving states, uncomfortable glaring caused by glare of a driver of the rear vehicle due to too high vehicle lamp brightness is avoided, and the road safety is improved.

In one embodiment, turning on the light at the tail of the driving vehicle and adjusting the light emission intensity of the light at the tail of the driving vehicle according to the light on command, the vehicle state information, the ambient brightness information and the vehicle distance information, comprises: and under the condition that the environment brightness information is larger than a preset brightness threshold value, controlling the lamp light at the tail of the driving vehicle to light according to the preset safe luminous intensity, wherein the preset safe luminous intensity can be determined according to national regulations or industry regulations.

After the lamplight starting instruction is acquired, the whole vehicle controller firstly compares the acquired environment brightness information with preset brightness threshold information, and if the environment brightness information is larger than the preset brightness threshold, for example, the preset brightness threshold can be 20lx, the vehicle lamp to be started can be indicated to be directly started by the driving vehicle to be lightened according to the preset safe luminous intensity. At the moment, the luminous intensity of the car lamp does not need to be reduced or gradually increased according to the brightness increment until the safety luminous intensity is preset, and uncomfortable glaring feeling is not generated for drivers of rear vehicles.

If the ambient brightness information is less than or equal to the preset brightness threshold, the ambient brightness information indicates that the driver of the rear vehicle is likely to generate uncomfortable glaring feeling if the vehicle is driven to directly light the vehicle lamp according to the preset safe luminous intensity. Therefore, the distance information of the vehicle, that is, the distance between the driving vehicle and the nearest vehicle behind, needs to be compared with a preset distance threshold value to further determine whether the driver of the vehicle behind can feel uncomfortable and glaring when the vehicle lamp is directly lightened according to the preset safe luminous intensity.

S202: and under the condition that the vehicle distance information is larger than a preset distance threshold value, controlling the light at the tail of the driving vehicle to light according to the preset safe luminous intensity.

If the distance between the driving vehicle and the rear nearest vehicle is greater than the preset distance threshold, the driving vehicle directly lights the vehicle lamp according to the preset safe luminous intensity, so that the driving vehicle driver cannot be influenced, namely uncomfortable glare is not caused to the rear vehicle driver, and the vehicle lamp can be directly lightened according to the preset safe luminous intensity.

In one embodiment, as shown in fig. 3, according to the light turning-on command, the vehicle state information, the ambient brightness information and the vehicle distance information, the light at the tail of the driving vehicle is turned on and the light luminous intensity of the light at the tail of the driving vehicle is adjusted, and the method further comprises:

s301: and judging whether the vehicle distance information is larger than a preset distance threshold value or not under the condition that the ambient brightness information is smaller than or equal to the preset brightness threshold value.

S302: and under the condition that the vehicle distance information is smaller than or equal to a preset distance threshold value, starting the light at the tail of the driving vehicle according to the vehicle state information and adjusting the luminous intensity of the light at the tail of the driving vehicle.

If the distance between the driving vehicle and the vehicle closest to the rear is smaller than the preset distance threshold, it indicates that the driving vehicle may affect the driver of the rear vehicle by directly lighting the lamp according to the preset safe luminous intensity, so that the luminous intensity of the lamp needs to be further adjusted by analyzing the vehicle state information, so that the luminous intensity is not too high to cause uncomfortable glaring of the driver of the rear vehicle.

In one embodiment, when the vehicle distance information is less than or equal to the preset distance threshold, turning on the light at the tail of the driving vehicle and adjusting the light intensity of the light at the tail of the driving vehicle according to the vehicle state information, including: and under the condition that the vehicle state information is parking state information, obtaining lamp parameter information and observer information, determining target luminous intensity according to the lamp parameter information, observer information, a preset glare formula and environment brightness information, controlling the luminous intensity of the lamp at the tail of the driving vehicle according to the target luminous intensity so that the light glare value at the tail of the current driving vehicle is smaller than a first preset glare value, wherein the lamp parameter information comprises lamp luminous area information and lamp position index information, the observer information comprises observation distance information and observation angle information of eyes of a driver in the closest position of the lamp at the tail of the vehicle and the rear of the vehicle, the lamp luminous area information can be the area of a luminous part of the lamp, the luminous area of each lamp can be prestored in a whole vehicle controller, the position index information of each lamp can refer to the angle and the position parameter of a light source relative to eyes, the position index of each lamp can be prestored in the whole vehicle controller, the observation distance information can comprise one of distance information between the center of a luminous part and eyes of a driver of the rear vehicle and distance information between the center of the luminous part of the lamp and eyes of a driver of the vehicle and a rear vehicle seat, and the angle information of the eyes of the lamp can comprise the angle information which is sandwiched between the surface of the eyes of the driver and the surface of the driver and the normal line of the surface of the driver.

It can be understood that the driving vehicle may be further provided with an image pickup device, the image pickup device may capture an image of the rear vehicle, the whole vehicle controller may acquire, in real time, angle information between a normal line of a surface of the light-emitting lamp and an eye direction of a driver of the rear vehicle and distance information between a center of the light-emitting part of the light-emitting lamp and eyes of the driver of the rear vehicle by analyzing the image information of the rear vehicle, or the whole vehicle controller may acquire, in real time, angle information between a normal line of the surface of the light-emitting lamp and a direction of a driver's seat of the rear vehicle and distance information between the center of the light-emitting part of the light-emitting lamp and a driver's seat of the rear vehicle by analyzing the image information of the rear vehicle, and may acquire, in real time, a glare value of the vehicle lamp by combining the environment brightness information acquired in real time with parameter information of each lamp and a preset glare formula stored in the whole vehicle controller. And under the condition that the vehicle distance information is smaller than or equal to a preset distance threshold value, the whole vehicle controller can analyze and calculate the glare value of the vehicle lamp through a formula (1), and under the condition that the vehicle distance information is larger than the preset distance threshold value, the whole vehicle controller can analyze and calculate the glare value of the vehicle lamp through a formula (2).

The UGR is unified glare value, E is environment indirect illuminance, I is lamp luminous intensity, A is lamp luminous surface area, a is an angle between a lamp surface normal and an observer eye direction, r is a distance between the center of a lamp luminous part and the observer eye, and P is a position index of an independent lamp.

In an exemplary embodiment, when information of turning on a position light at the rear of the vehicle is received and current information of the driving vehicle satisfies that the ambient brightness information is less than or equal to a preset brightness threshold, a distance between the driving vehicle and a vehicle closest to the rear is less than a preset distance threshold, and the driving vehicle is in a parking state, the vehicle controller determines a critical value of a target luminous intensity of the position light according to formula (1), a first preset glare value, lamp parameter information, observer information acquired in real time, and the ambient brightness information, and ensures that the position light glare value is less than the first preset glare value.

In one embodiment, as shown in fig. 4, in the case that the vehicle distance information is less than or equal to the preset distance threshold, according to the vehicle state information, starting the light at the tail of the driving vehicle and adjusting the light emitting intensity of the light at the tail of the driving vehicle, the method further includes:

s401: and judging whether the current vehicle speed is greater than a first preset vehicle speed or not under the condition that the vehicle state information is deceleration state information.

It will be appreciated that when the vehicle is in a decelerating state, for example, the speed of the vehicle is reduced from 30km/h to 15km/h and the speed of the vehicle is reduced from 10km/h to 5km/h, the faster the vehicle speed, the less the light at the tail of the vehicle affects the driver of the vehicle behind; the slower the vehicle speed, the greater the influence of the light at the tail of the vehicle on the driver of the rear vehicle. Therefore, when the vehicle is in a decelerating state, it is also necessary to further judge according to the running speed of the driving vehicle to adjust the luminous intensity of the lamp light at the tail.

S402: and under the condition that the vehicle speed is greater than a first preset vehicle speed, controlling the light at the tail of the vehicle to light according to the preset safe luminous intensity.

Under the condition that the running speed of the driving vehicle is greater than a first preset vehicle speed, uncomfortable glare cannot be caused to a driver of a rear vehicle when the light at the tail of the vehicle is directly lightened according to the preset safe luminous intensity, and the first preset vehicle speed can be 10km/h. For example, when the information of turning on the position lamp at the rear of the vehicle is received and the current information of the driving vehicle satisfies the environmental brightness information at the same time that the environmental brightness information is less than or equal to the preset brightness threshold, the distance between the driving vehicle and the nearest vehicle at the rear is less than the preset distance threshold, and the driving vehicle starts decelerating from the running speed of 40km/h, the whole vehicle controller controls the position lamp to be directly lighted according to the preset safe luminous intensity.

In one embodiment, as shown in fig. 5, in the case that the vehicle distance information is less than or equal to the preset distance threshold, according to the vehicle state information, turning on the light at the tail of the driving vehicle and adjusting the light emitting intensity of the light at the tail of the driving vehicle, the method further includes:

s501: and judging whether the current vehicle speed is greater than a second preset vehicle speed or not under the condition that the current vehicle speed is smaller than a first preset vehicle speed, wherein the second preset vehicle speed is greater than the first preset vehicle speed.

If the current speed is smaller than the first preset speed, the driving vehicle directly lights the vehicle lamp according to the preset safe luminous intensity to influence the driver of the rear vehicle, and the speed of the driving vehicle needs to be further judged.

S502: and under the condition that the current vehicle speed is greater than a second preset vehicle speed, acquiring lamp parameter information and observer information, determining target luminous intensity according to the lamp parameter information, the observer information, a preset glare formula and environment brightness information, and controlling the luminous intensity of lamplight at the tail of the driving vehicle according to the target luminous intensity so as to enable the glare value of the lamplight at the tail of the current driving vehicle to be smaller than the second preset glare value.

When the speed of the driving vehicle is between a first preset speed and a second preset speed, the whole vehicle controller determines a critical value of target luminous intensity of lamplight at the tail of the vehicle according to the acquired observer information, environment brightness information and preset lamp parameter information, a formula (1) and a second preset glare value, and ensures that the lamp glare value is smaller than the second preset glare value, wherein the second preset speed can be 5km/h. The driving vehicle is traveling at a constant speed at a speed of 8km/h, the ambient brightness information is smaller than a preset brightness threshold value, the distance between the driving vehicle and the rear vehicle is larger than a preset distance threshold value, the whole vehicle controller receives information for starting a rear fog lamp at the tail of the vehicle, then the rear fog lamp is lightened according to preset safe luminous intensity, the driving vehicle starts decelerating at a constant speed after traveling at a constant speed for a period of time, the whole vehicle controller acquires and judges that the vehicle distance information is smaller than the preset distance threshold value, then the critical value of the target luminous intensity of the rear fog lamp is determined according to the acquired observer information, the ambient brightness information, the preset lamp parameter information, the formula (1) and the second preset glare value, and the luminous intensity of the rear fog lamp is adjusted, so that the luminous intensity of the rear fog lamp is smaller than the critical value, and the glare value of the rear fog lamp is smaller than the second preset glare value.

S503: and under the condition that the vehicle speed is smaller than a second preset vehicle speed, acquiring lamp parameter information and observer information, determining target luminous intensity according to the lamp parameter information, the observer information, a preset glare formula and environment brightness information, and controlling the luminous intensity of lamplight at the tail of the driving vehicle according to the target luminous intensity so as to enable the glare value of the lamplight at the tail of the current driving vehicle to be smaller than a first preset glare value.

For example, the first preset vehicle speed may be 10km/h, the second preset vehicle speed may be 5km/h, the driving vehicle is traveling at a constant speed from 8km/h, at this time, the ambient brightness information is smaller than the preset brightness threshold, the distance between the driving vehicle and the rear vehicle is greater than the preset distance threshold, the whole vehicle controller receives the information of turning on the rear fog lamp at the tail of the vehicle, and then lights the rear fog lamp according to the preset safe light intensity, after the driving vehicle travels at a constant speed for a period of time, the speed is reduced from a constant speed state, at this time, the whole vehicle controller obtains and judges that the vehicle distance information is smaller than the preset distance threshold, so that the light intensity of the rear fog lamp is controlled by the whole vehicle controller to be reduced to be smaller than the second preset glare value, and the light intensity of the rear fog lamp is adjusted again when the vehicle speed of the driving vehicle is reduced to be 5km/h along with the continuous reduction of the vehicle speed, and the light intensity of the rear fog lamp is adjusted to be smaller than the first preset glare value.

Through setting up two default glare values, can realize the refined control to car light glare value, adjust the luminous intensity of driving vehicle car light according to different circumstances, make the luminous intensity of car light be unlikely to too high and arouse rear vehicle driver's discomfort, avoid the luminous intensity of car light to be too low and lead to other road users to be difficult to perceive this driving vehicle simultaneously, fully guarantee traffic road safety. In the application, only two preset glare values are set, and the number of the preset glare values can be increased according to different requirements in practice so as to further refine control.

In one embodiment, as shown in fig. 6, in the case that the vehicle distance information is less than or equal to the preset distance threshold, according to the vehicle state information, turning on the light at the tail of the driving vehicle and adjusting the light emitting intensity of the light at the tail of the driving vehicle, the method further includes:

s601: and judging whether the current vehicle speed is greater than a first preset vehicle speed or not under the condition that the current vehicle state information is acceleration state information.

It will be appreciated that when the vehicle is in an accelerating state, for example, the vehicle is accelerated from 15km/h to 30km/h and the vehicle is accelerated from 5km/h to 10km/h, the faster the vehicle speed, the less the light at the tail of the vehicle affects the driver of the vehicle behind; the slower the vehicle speed, the greater the influence of the light at the tail of the vehicle on the driver of the rear vehicle. Therefore, when the vehicle is in a decelerating state, it is also necessary to further judge according to the running speed of the driving vehicle to adjust the luminous intensity of the lamp light at the tail.

S602: and under the condition that the current speed is smaller than the first preset speed, controlling the luminous intensity of the lamp at the tail of the vehicle to gradually increase according to the target brightness increment until the preset safe luminous intensity is reached.

Under the conditions that the ambient brightness information is smaller than or equal to a preset brightness threshold value and the distance between the driving vehicle and the nearest vehicle behind is smaller than a preset distance threshold value, the driving vehicle is accelerated and started from a parking state, namely the current vehicle speed is 0, in order to avoid uncomfortable glare to a driver of the rear vehicle caused by directly starting a vehicle lamp according to the preset safe luminous intensity, the luminous intensity of the whole vehicle controller controls the lamp to be gradually increased according to the target brightness increment until the preset safe luminous intensity is reached, and because the vehicle is accelerated to run, when the luminous intensity of the vehicle lamp reaches the preset safe luminous intensity, the relative distance between the driving vehicle and the vehicle behind is also increased, so uncomfortable glare cannot be caused to the driver of the rear vehicle.

S603: and under the condition that the current speed is greater than the first preset speed, controlling the lamp at the tail of the vehicle to light according to the preset safe luminous intensity.

When the driving vehicle starts accelerating from a running state that the current speed is greater than a first preset speed, the whole vehicle controller judges whether the current speed is greater than the first preset speed, and under the condition that the current speed is greater than the first preset speed, the lamp is controlled to be lightened according to the preset safe luminous intensity or the lamp is controlled to be restored to the preset safe luminous intensity.

In one embodiment, when the driving vehicle is traveling at a constant speed higher than a first preset vehicle speed and the ambient brightness information is less than or equal to a preset brightness threshold and the distance between the driving vehicle and the nearest vehicle behind is less than a preset distance threshold, the controller directly lights the lamp or controls the lamp to restore to the preset safe luminous intensity according to the preset safe luminous intensity after receiving the light turning-on command.

When the running speed of the driving vehicle is higher than the first preset vehicle speed, the light at the tail of the vehicle is directly lightened according to the preset safe luminous intensity, so that uncomfortable glare is not caused to the driver of the rear vehicle. For example, when the driving vehicle is traveling at a constant speed of 50km/h, and when the information of turning on the position lamp at the rear of the vehicle is received and the current information of the driving vehicle simultaneously satisfies that the ambient brightness information is less than or equal to a preset brightness threshold value and the distance between the driving vehicle and the nearest rear vehicle is less than a preset distance threshold value, the whole vehicle controller controls the position lamp to be directly lighted according to the preset safe luminous intensity.

In application, when the driving vehicle runs at a constant speed which is smaller than a first preset vehicle speed but higher than a second preset vehicle speed, and the ambient brightness information is smaller than or equal to a preset brightness threshold value and the distance between the driving vehicle and the nearest vehicle at the rear is smaller than a preset distance threshold value, the controller can acquire lamp parameter information and observer information after receiving the lamp starting instruction, determine target luminous intensity according to the lamp parameter information, the observer information, a preset glare formula and the ambient brightness information, and control the luminous intensity of the lamp at the tail of the driving vehicle according to the target luminous intensity so that the lamp glare value at the tail of the current driving vehicle is smaller than the second preset glare value.

When the driving vehicle runs at a constant speed which is smaller than a second preset speed, the ambient brightness information is smaller than or equal to a preset brightness threshold value, and the distance between the driving vehicle and the nearest vehicle behind is smaller than a preset distance threshold value, the controller receives the light starting instruction, acquires the lamp parameter information and the observer information, determines the target luminous intensity according to the lamp parameter information, the observer information, the preset glare formula and the ambient brightness information, and controls the luminous intensity of the light at the tail of the driving vehicle according to the target luminous intensity so that the glare value of the light at the tail of the current driving vehicle is smaller than a first preset glare value.

In one embodiment, a display device is installed in the vehicle, when the controller receives a light starting instruction for starting a certain lamp at the tail of the vehicle and the lamp is in a fault state, the display device sends out prompt information, and meanwhile, the controller lights other lamps to serve as replacement lamps. For example, the controller receives an instruction to turn on the position light at the tail of the vehicle, and the position light is in a fault state, the controller lights the rear fog light to serve as a substitute lamp for the position light, and meanwhile, the display device sends out prompt information until the rear fog light is repaired after the fault, and the display device can comprise one of a central control display screen, a liquid crystal instrument panel and a head-up display.

In one embodiment, a display device and a set of spare lamp system are installed on the vehicle, when the controller receives a lamp starting instruction for starting a certain lamp at the tail of the vehicle and the lamp is in a fault state, the display device sends out prompt information, and meanwhile the controller lights the spare lamp to serve as a replacement lamp.
