Vehicle adaptive cruise control method, device, vehicle and storage medium

Abstract

The embodiments of this specification provide a vehicle adaptive cruise control method, device, vehicle and storage medium. The method includes: obtaining initial decision-making elements when the vehicle is driving, the initial decision-making elements at least including the driving speed of the vehicle, the driving speed of the preceding vehicle, and the distance between the vehicle and the preceding vehicle; given a random cruise strategy, and predict the predicted decision-making elements after executing the random cruising strategy according to the initial decision-making elements; determine the size of the enhanced signal according to the predicted decision-making elements; judge whether the random cruising strategy is based on the size of the enhanced signal Accurate; if yes, use the random cruise strategy to control the driving of the vehicle. The vehicle adaptive cruise control method provided by the embodiment of this specification can automatically learn the adaptive cruise control strategy without manually setting the control mode, and can improve the stability and adaptability of the vehicle adaptive cruise control.

Description

technical field [0001] The embodiments of this specification relate to the technical field of vehicle control, and in particular to a vehicle adaptive cruise control method, device, vehicle and storage medium. Background technique [0002] The adaptive cruise control system (ACC) is based on the traditional constant speed cruise control combined with the control of keeping the distance between vehicles, and monitors the driving environment ahead through the environmental information perception module, such as monitoring whether there is a vehicle ahead, the distance between the two, and the relative speed, etc. , and adopt different control strategies to drive according to different environments. On the one hand, the adaptive cruise control system can effectively avoid collisions, and on the other hand, it can reduce the operating burden of the driver's license in the case of long-distance driving. [0003] The technology of adaptive cruise control is mainly used in ordinar...

AI Technical Summary

Problems solved by technology

Among them, the analysis and classification of the test data is subjective to a certain extent, and it is difficult to list all the speeds, the relative speed of the vehicle in front, the distance of the vehicle in front, and the longitudinal acceleration / deceleration (brake, accelerator).

Therefore, the adaptive cruising method of supervised learning is not stable and adaptable.
