Description

Method, device, vehicle and storage medium for adjusting following distance

technical field

The present application relates to the technical field of vehicle intelligent driving, and in particular to a method, device, vehicle and storage medium for adjusting the following distance.

Background technique

With the improvement of people's living standards, people have a higher pursuit of the car's assisted driving function. In order to meet the needs of users for the car's assisted driving function, the currently equipped driving assistance systems are mainly L1-L2 driving assistance systems. Among them, the L1 driving assistance system can assist the vehicle to complete the longitudinal control function, and the L2 driving assistance system includes the low-order longitudinal assistance control function and the high-order horizontal and vertical assistance control function. The longitudinal control function of the driving assistance system is mainly divided into two working conditions: when there is no other vehicle ahead, the driving assistance system controls the vehicle to drive at the speed set by the user; when there are other vehicles ahead, if the driving speed is lower than the driving speed set by the user The driving assistance system controls the vehicle to follow the vehicle in front or stop.

In related technologies, most of the time-distance gears are used to adjust the following distance between the current vehicle and the vehicle in front when the driving assistance system is working.

However, adjusting the following distance between the current vehicle and the vehicle in front by setting the time distance mainly has the following problems:

(1) In a complex road traffic environment, when the driver assistance system is working, if the types of target vehicles in front are diverse, for example, the vehicles in front are large vehicles such as trucks, trailers, special vehicles, or common cars, sports utility vehicles, etc. Small vehicles such as cars, or non-motorized vehicles such as bicycles and tricycles. During the driving process of the vehicle, due to the different types of target vehicles in front, the difference in the subjective sense of oppression brought to the user and the objective unsafe factors are also different. The user's sense of oppression is much greater than that of a car, and there are also greater safety hazards. Therefore, when the target type of the vehicle in front changes, the user may frequently adjust the time distance to ensure that the vehicle remains in line with the vehicle in front. At a relatively comfortable distance, when the entire driving assistance system is working, the user experience will be poor due to frequent adjustment of the following distance.

(2) Based on the scenario described in the above question, in order to reduce the sense of oppression and unsafe factors brought by the vehicle in front, the user will frequently adjust the following time when the driving assistance system is working, so that the steering wheel buttons, knobs, scroll wheels and other hardware Bringing a greater burden will also make the reliability and durability of the hardware more severely tested, and at the same time increase the pressure on the cost of the vehicle.

(3) When the driving assistance system is working, if the current vehicle stops, the current vehicle will follow and stop. If the following time distance set by the user is relatively large at this time, it is easy to be blocked by other vehicles, which will affect the user's traffic efficiency and will Generate a sense of distrust for the driving assistance system, thereby reducing the user's driving experience.

Specifically, if the type of the target vehicle is a large vehicle, the following distance between the current vehicle and the target vehicle is determined according to the vehicle type, for example, the following distance is E meters, and the preset distance is D meters, and then the current vehicle is controlled according to the following distance. The vehicle travels, where E is less than or equal to D.

Optionally, if the type of the target vehicle is a non-motorized vehicle, the following distance between the current vehicle and the target vehicle is determined according to the vehicle type, for example, the following distance is F meters, and then the current vehicle is controlled according to the following distance, where F Less than or equal to E.
