Specifically, the navigation information may be obtained from a vehicle navigation system, the obstacle information may be obtained from a front radar of the vehicle, and the front video information may be obtained from a front windshield camera of the vehicle.
When the vehicle lamp is turned on, the road type is determined by combining the video information in front of the vehicle according to the navigation information, the vehicle lamp is controlled to switch the high beam or the low beam by combining the barrier information, the road type and the video information in front of the vehicle, the identification accuracy is higher without relying on the identification of the video information in front of the vehicle, and different control schemes are arranged aiming at different road types, so that the vehicle lamp has higher stability, and the driving experience of a user can be effectively improved.

The navigation road information includes information such as the current position of the vehicle, the current road type, and the like. From the navigation information, the information that the current running road is an expressway, a national road, a provincial road or a road in a city area, whether an isolation zone is arranged in the middle of the road and the like can be obtained.
According to the method and the device, the type of the current road is judged by combining navigation road information and vehicle front video information, and the type of the current road comprises a structured road and an unstructured road. The structured road specifically refers to a road provided with a middle isolation belt, and on the road where vehicles are located, only the vehicles in the same direction run, such as an expressway; the unstructured road specifically refers to a road without a middle isolation strip, the width of the road is small, the isolation strip is not arranged between two lanes, and when a vehicle turns on a high beam light, the driving of opposite vehicles is affected.
As an example, in the navigation road information, the information of the current road type, whether the current road is provided with the isolation zone, and whether the current road can turn around can be accurately obtained. If the current road type can be definitely known to be structured roads such as expressways, urban expressways and the like, determining the current road type by taking the navigation road information as a standard; and if the current road type cannot be accurately judged from the navigation information, determining the current road type by taking the scene information in the video information in front of the vehicle as the standard.
In the embodiment, the judgment of the road type integrates the scene information in the video information in front of the vehicle and the navigation road information in the navigation system, so that the judgment accuracy of the road type is higher.
In one embodiment, the controlling the vehicle light to switch between a high beam and a low beam according to the obstacle information, the road type, and the front video information specifically includes:

and carrying out target identification on the video information in front of the vehicle, fusing the obstacle information, and determining the type and state of the obstacle.
The front radar of the automobile is a front millimeter wave radar arranged at a front grille, can monitor obstacles in front of the automobile in real time, and outputs the size of the obstacles, the relative distance between the obstacles and the automobile and the relative speed. The obstacle information detected by the radar is fused with the obstacle identified by the video information in front of the vehicle, so that the type and the state of the obstacle can be more accurately obtained.
After the type and the state of the obstacle are acquired, the vehicle lamp is controlled to switch between a high beam and a low beam by combining the type of the road. Different control strategies are arranged aiming at different road types, so that the switching of the high beam and the low beam of the car lamp can meet the driving requirements better, and the driving experience is improved.
In one embodiment, the type of the obstacle comprises a front vehicle, and the obstacle state comprises a lane where the obstacle is located and the distance between the obstacle and the vehicle;
the controlling the vehicle lamp to switch between the high beam and the low beam according to the road information, the type of the obstacle and the state of the obstacle specifically comprises:
when the road type is a structured road,
if the detected lane of the front vehicle is the own lane, and
the distance between the front vehicle and the vehicle is smaller than a first distance threshold value;
controlling the vehicle lamp to be a dipped headlight;
otherwise, the vehicle lamp is controlled to be a high beam.
The embodiment of the application specifically explains the high-beam and low-beam light switching strategy on the structured road, and in the structured road, as the isolation belts are arranged between the two-way lanes, the isolation belts can shield the light of the vehicles on the opposite lanes, the vehicles can not influence the opposite vehicles when opening the high-beam light, and pedestrians are not allowed on the structured road. Therefore, for the structured road, the switching of the high beam and the low beam is controlled only according to the front vehicle.
For the structured road, only the front vehicle is identified, and in the front video information, because of the night environment, the identification of the front vehicle determines whether the front vehicle is a vehicle by identifying the automobile tail lamp, and determines the distance from the front vehicle to the vehicle by combining the obstacle information acquired by the automobile front radar. For the recognition of automobile tail lamps in the video information in front of the automobile, in a structured road, light leaked from the isolation belt can be intelligently filtered during target recognition, so that the accuracy of the target recognition is improved.
When the vehicle travels at night, the vehicle light is defaulted to be a high beam when being turned on, only when the vehicle is detected to be within a first distance threshold in front of the vehicle lane, the vehicle light is switched to be a low beam, and the vehicle light is switched to be a high beam until the distance between the front vehicle and the vehicle is larger than or equal to the first distance threshold, wherein the first distance threshold can be set to be 60-65 m.
In this embodiment, on a structured road such as an expressway or an urban expressway, where an intermediate isolation strip is provided, when it is detected that there is a vehicle in a first distance threshold range in front of the vehicle lane, the vehicle lights are controlled to be low beam lights, so as to prevent a preceding vehicle from reflecting light of a high beam of the vehicle and affecting driving of a driver of the vehicle.
In one embodiment, the barrier types comprise oncoming vehicles, co-directional vehicles and pedestrians, and the barrier state comprises a distance of the barrier from the host vehicle;
the controlling the vehicle lamp to switch between a high beam and a low beam according to the road information, the type of the obstacle and the state of the obstacle specifically comprises:
when the road type is an unstructured road,
if a co-directional vehicle is detected within a first distance threshold, or
Detecting an oncoming vehicle within a second distance threshold, or
Detecting a pedestrian within a third distance threshold;
controlling the vehicle lamp to be a dipped headlight;
otherwise, the vehicle lamp is controlled to be a high beam.
The embodiment of the application specifically explains the high-beam and low-beam light switching strategy on the unstructured road, and in the unstructured road, the road is narrow, no isolation belt is arranged, so that the road condition is complex, the same-direction vehicles need to be detected, and opposite-direction vehicles and pedestrians need to be detected. For the distinction between the co-directional vehicle and the opposite vehicle, the vehicle lights are specifically identified according to the front video signal, when the vehicle lights are identified as the front lights of the vehicle, the vehicle is the opposite vehicle, and when the vehicle lights are identified as the tail lights of the vehicle, the vehicle is the co-directional vehicle. For distinguishing pedestrians from vehicles, the shape of an obstacle is identified according to a radar in front of an automobile.
Specifically, when driving at night, the vehicle light defaults to a high beam when turned on, and the vehicle light is switched to a low beam only in the following three cases: firstly, when a vehicle in the same direction is detected within a first distance threshold value, switching the vehicle lamp to a dipped headlight, and switching the vehicle lamp to a high beam until the distance between the vehicle in the same direction and the vehicle is greater than or equal to the first distance threshold value; when an opposite vehicle is detected within a second distance threshold value, the vehicle is switched to a low beam light, and the vehicle light is switched back to a high beam light until the opposite vehicle disappears in the video picture; and thirdly, when the pedestrian is detected within the third distance threshold, the vehicle is switched to be a dipped headlight, and until the pedestrian disappears in the video picture, the vehicle light is switched to be a high beam.
In this embodiment, on an unstructured road which drives in two directions such as a city road and a rural road and is not provided with an isolation strip, when a vehicle, an oncoming vehicle or a pedestrian in the same direction is detected within a set distance, the vehicle light is controlled to be a dipped headlight, so that driving interference of a high beam on the oncoming vehicle and influence on the sight of the pedestrian are avoided, and a front vehicle reflects light of the high beam of the vehicle to influence the driving of a driver of the vehicle.
