Further, in step S30, the step of performing the reminding operation on the target vehicle according to the light status includes:
and D, if the light state is a high beam state, performing reminding operation on the target vehicle, wherein the reminding operation comprises double-flash reminding.
In this embodiment, the brightness value of the image is compared with a preset brightness threshold, where the brightness value may be an average brightness value of the image, and if the average brightness value in the image is greater than or equal to the preset brightness threshold, it is determined that the light state of the target vehicle is a high beam state, which indicates that the high beam is turned on by the target vehicle, and a driver of the vehicle may be interfered by the high beam of the opposite vehicle, and if the high beam is used to meet the vehicle, the light is directly emitted to the driver, so that the driver may glare and affect the line of sight, which may cause a safety accident, and at this time, a warning operation needs to be performed on the target vehicle, and if the brightness value in the image information is less than the preset brightness threshold, it is determined that the light state of the target vehicle is not the high beam state, the vehicle may be in a normal dipped headlight state or other non-high beam state, which means that the oncoming vehicle does not turn on the high beam, and the vehicle is not interfered by the high beam of the oncoming vehicle, so that the target vehicle does not need to be reminded. The preset brightness threshold is a preset brightness threshold used for judging the light state of the target vehicle, and the reminding operation comprises double-flash reminding. In this embodiment, the image information of the target vehicle may be captured by using the existing driving assistance front camera in the vehicle, so as to save the development cost of new parts. As shown in fig. 3, the vehicle turns on the IHMA intelligent high beam and low beam switching function, and then monitors the headlight state of the vehicle in the opposite lane through the front driving assistance camera, that is, the front driving assistance camera takes an image of the vehicle in the opposite lane, and analyzes and judges whether the opposite vehicle turns on the high beam according to the brightness value in the image, and if the opposite vehicle turns on the high beam, the opposite vehicle is prompted by double flashing.

In this embodiment, before the step of performing the reminding operation on the target vehicle according to the light state, the vehicle speed of the target vehicle may be further obtained, and whether the vehicle speed of the target vehicle is greater than a preset vehicle speed threshold is determined, where the vehicle speed of the target vehicle is measured by a vehicle speed sensor, and the preset vehicle speed threshold is a preset vehicle speed and is used for determining whether the vehicle speed of the target vehicle is too great, and the greater the vehicle speed of the target vehicle is, the greater the safety risk of a traffic accident is, for example, the preset vehicle speed threshold may be set to 30km/h, and if the vehicle speed of the target vehicle is greater than the preset vehicle speed threshold, it is determined that the vehicle speed of the target vehicle is too great, and at this time, if a high beam is turned on at the same time when the vehicle speed of the target vehicle is too great, the probability of the traffic safety risk is greater, and therefore, when the vehicle speed of the target vehicle is greater than the preset vehicle speed threshold, the target vehicle needs to be further reminded according to the light state, namely, the following steps are executed: and reminding the target vehicle according to the light state. And if the speed of the target vehicle running by driving the high beam lamp at night is more than 30km/h, the vehicle carries out reminding operation on the target vehicle. Optionally, when the vehicle speed of the target vehicle is less than or equal to the preset vehicle speed threshold, it indicates that the vehicle speed of the target vehicle is not high, and the risk of traffic safety accidents is relatively low at the safe and controllable vehicle speed, in this embodiment, to avoid frequent double-flashing prompting, when the vehicle speed of the target vehicle is less than or equal to the preset vehicle speed threshold, the subsequent step of performing a reminding operation on the target vehicle according to the light state is not performed, as another embodiment, the user may set the vehicle speed threshold to be a vehicle speed threshold below the preset vehicle speed threshold, for example, set the preset vehicle speed threshold to be any vehicle speed threshold below 0 or 30 km/h. The preset vehicle speed threshold value can be adjusted within a certain range according to actual conditions, and the driving habit of a driver in the actual driving process of the vehicle is better met.
In this embodiment, before the reminding operation is performed on the target vehicle according to the light state, the vehicle speed of the target vehicle is judged, and when the vehicle speed of the target vehicle is greater than the preset vehicle speed threshold, the reminding operation is further performed on the target vehicle according to the light state.

step F, obtaining the driving intention of the target vehicle according to the image;
and G, performing reminding operation on the target vehicle according to the driving intention.
The traditional IHMA intelligent high-low beam switching function can not remind the driver of the opposite side in time when vehicles in opposite lanes attempt to cross the double solid lines and illegally overtake, cannot avoid the influence on the driver of the vehicle and has the risk of traffic accidents.
In the embodiment, the image of the target vehicle is acquired, and according to the image information of the target vehicle, the driving intention of the target vehicle can be acquired, in the embodiment, the image information of the target vehicle includes the target vehicle and the environment around the target vehicle, specifically, the image of the target vehicle includes the target vehicle and the lane line, the lane lines in the image information are lane lines indicating that the vehicle is strictly prohibited from passing over the lane or running on the lane, for example, the double solid lines, which are taken as an example in the present embodiment, are used to acquire lane lines in the image information, and to acquire the contour of the target vehicle in the image information, analyzing and obtaining the driving intention of the target vehicle according to the lane line in the image and the outline of the target vehicle, the target vehicle is reminded according to the driving intention, and the contour of the target vehicle in the embodiment may be a contour boundary of the target vehicle in the image.
In the embodiment, by obtaining the lane lines in the image information and the contour of the target vehicle in the image information, whether the target vehicle attempts to cross the double solid lines for illegal overtaking can be judged, and then whether the target vehicle needs to be reminded or not is judged.
Further, in the step F, the step of refining the driving intention of the target vehicle according to the image includes:
step f1, acquiring a lane line in the image and acquiring a vehicle contour of the target vehicle in the image;
step f2, determining the lane line area where the lane line is located in the image, and determining the outline area where the vehicle outline is located in the image;
and f3, if the lane line area is overlapped with the outline area, determining that the driving intention of the target vehicle is illegal overtaking.
In this embodiment, a specific process of obtaining the driving intention of the target vehicle according to the image may be: the method comprises the steps of obtaining a lane line in an image of a target vehicle, obtaining a vehicle outline of the target vehicle in the image, further determining a lane line area where the lane line is located in the image, determining a contour area where the vehicle outline is located in the image, wherein the lane line area and the contour area can be pixel areas in the image, obtaining driving intention of the target vehicle according to the lane line area and the contour area, specifically, if the lane line area and the contour area are overlapped, the situation that the target vehicle has violation overtaking behaviors of line pressing and overtaking exists, determining that the driving intention of the target vehicle is violation overtaking at the moment, needing to remind a driver of the target vehicle to stop violation overtaking in time, and reducing the safety risk of traffic accidents, further, if the lane line area and the contour area are not overlapped, the situation that the target vehicle has no violation overtaking behaviors of line pressing, at this time, it is determined that the driving intention of the target vehicle is normal driving, and the reminding operation of the target vehicle is not needed.
As another embodiment, the image of the target vehicle may be monitored by the camera in real time, the lane line region where the lane line is located in the image is determined, the contour region where the vehicle contour is located in the image is determined, all contour coordinates in the contour region are further determined, whether the contour coordinates exist in the lane line region is detected, if the contour coordinates of the target vehicle exist in the lane line region, a behavior that the target vehicle violates the rule of pressing and overtaking on the lane line is indicated, at this time, the driving intention of the target vehicle is determined to violate the rule of overtaking, and the target vehicle is reminded.
Further, before the step of performing the reminding operation on the target vehicle according to the driving intention, the step G includes:
step h1, acquiring the relative distance between the vehicle and the target vehicle;
step h2, if the relative distance is less than the preset safe distance, executing the steps of: and reminding the target vehicle according to the driving intention.
In this embodiment, before the step of performing the reminding operation on the target vehicle according to the driving intention, a relative distance between the host vehicle and the target vehicle may be obtained, the relative distance between the target vehicle and the host vehicle may be detected by a radar (e.g., a millimeter wave radar), and it is determined whether the relative distance between the target vehicle and the host vehicle is smaller than a preset safety distance, where the preset safety distance is a safety distance preset according to a plurality of tests, and the preset safety distance is used to determine whether the relative distance between the target vehicle and the host vehicle is too short, and the closer the relative distance is, the greater the risk of occurrence of a traffic safety accident is, for example, the preset safety distance may be set to 10 meters, and if the relative distance is smaller than the preset safety distance by 10 meters, it is determined that the relative distance between the host vehicle and the host vehicle is too close, and the reaction time for the host vehicle to change the driving intention is shorter, if the high beam is turned on at the same time under the condition that the relative distance is too short, the probability of occurrence of traffic safety risk is higher, and therefore when the relative distance is smaller than the preset safety distance, the target vehicle needs to be further reminded according to the driving intention, namely, the subsequent steps are executed: and reminding the target vehicle according to the driving intention. As shown in fig. 3, the vehicle starts the IHMA intelligent high-low beam switching function, and then monitors the vehicle driving intention of the opposite lane through the driving assistance front camera, that is, the driving assistance front camera captures an image of the vehicle in the opposite lane, the driving intention of the opposite vehicle is obtained through the lane line information in the image and the vehicle profile information of the target vehicle, and then whether the opposite vehicle crosses the double solid lines is judged, and if the opposite vehicle crosses the double solid lines, the opposite vehicle is prompted by double flashing. Further, if the relative distance is greater than or equal to the preset safe distance, it indicates that the relative distance between the vehicle and the vehicle is relatively far, and the distance is within a safe and controllable distance, and at this time, the risk of a traffic safety accident is relatively small.
If the driving assistance device is shown in fig. 3, the lighting state of the target vehicle and the driving intention of the target vehicle can be detected simultaneously through the driving assistance front camera, and the lighting state and the driving intention are analyzed simultaneously, so that double-flash reminding can be performed on the target vehicle according to the lighting state and the driving intention, and the driving safety in the vehicle meeting process is improved. When the vehicle runs, a driver starts an IHMA intelligent high-beam and low-beam switching function, monitors a vehicle in front through a driving auxiliary front camera, and accurately identifies the light state and the running intention of the vehicle in an opposite lane; if the high beam is turned on by the vehicle in the opposite lane, the opposite vehicle is reminded of double flashing, and if the vehicle in the opposite lane is recognized to try to cross the double solid lines, the opposite vehicle is reminded of double flashing when illegal overtaking is carried out.
In the embodiment, before the step of performing the reminding operation on the target vehicle according to the driving intention, the relative distance between the vehicle and the target vehicle is further obtained, and when the relative distance is smaller than the preset safety distance, the reminding operation is further performed on the target vehicle according to the driving intention. The risk of traffic accidents possibly occurring when vehicles in opposite lanes close to each other at a relative distance attempt to cross the double solid lines for illegal overtaking is effectively reduced, and the vehicles meet more safely.
