Problems solved by technology

[0004]However, in the traditional motion control method, under the influence of factors such as working condition switching or emergency braking, the theoretical acceleration output by the closed-loop control may have a sudden change, resulting in The granularity of vehicle speed control is relatively coarse, which in turn affects the comfort of the vehicle

Abstract

The invention relates to a vehicle acceleration processing method and device, a vehicle and a storage medium. The method comprises the steps of obtaining a theoretical acceleration and a current actual speed in a current time period; determining a target acceleration change rate from a preset first mapping relation according to the theoretical acceleration of the current time period and the current actual speed; based on the target acceleration change rate and the theoretical acceleration of the current time period, processing the actual acceleration of the previous time period; and obtaining the actual acceleration of the current time period. That is to say, according to the acceleration processing method of the vehicle, the actual acceleration value with slow acceleration change can be obtained through the calculation process according to the obtained large theoretical acceleration value in the current time period, so that the granularity of the acceleration change is finer; in other words, an acceleration value with large change is converted into an acceleration value with smooth transition, so that the problem of poor comfort of the vehicle in the running process caused by sudden acceleration change is avoided, and the comfort of the whole vehicle is improved.

Description

technical field [0001] The present application relates to the technical field of automatic driving, in particular to a vehicle acceleration processing method, device, vehicle and storage medium. Background technique [0002] With the rapid development of the Internet of Things and artificial intelligence, and the gradual penetration into the automotive industry, the automatic driving technology of vehicles has gradually matured and gradually introduced to the market. In the application of automatic driving technology, it mainly includes three core technologies of environmental perception, path planning and motion control. Among them, motion control is the last link, and its main purpose is to realize path tracking. The longitudinal tracking is mainly based on the trajectory of path planning. The closed-loop control of the points and the pose of the self-vehicle is performed to obtain the final theoretical acceleration, which will directly affect the comfort, stability and tr...
