Abstract

The invention discloses a vehicle control method, a vehicle and a storage medium. The method comprises the steps that a vehicle running state is obtained, a gear selecting target is generated according to the vehicle running state, and an electric cylinder is controlled to drive a gear selecting block to vibrate till the gear selecting block begins to move; the total displacement of the gear selecting block moving from the initial position to the gear selecting target is calculated, and first PID control is carried out according to the real-time displacement and the real-time speed of the gearselecting block, so that the real-time speed of the gear selecting block reaches a preset value; secondary PID control is carried out according to the gear selecting target and the real-time displacement and the real-time speed of the gear selecting block, so that the gear selecting block reaches a target range corresponding to the gear selecting target, and the speed is 0 when the gear selectingblock reaches the gear selecting target range; and the electric cylinder is controlled to drive the gear selecting block to keep vibrating until the driving force of the electric cylinder is reducedto 0. According to the vehicle control method, the problem of unstable gear selection control of an automatic gearbox is solved.

Description

technical field [0001] The invention relates to the field of vehicle control, in particular to a vehicle control method, a vehicle and a storage medium. Background technique [0002] An automatic transmission is a transmission device that can automatically shift gears according to the vehicle speed and engine speed compared to the manual transmission. When switching gears, it is usually based on the target gear. gear to realize gear switching. In the prior art, the general actuators for gear selection are motors or electromagnets. The electromagnet-based gear selection control methods of automatic transmissions vary depending on the manufacturer. The gear selection control methods in the prior art are not stable enough. [0003] The above content is only used to assist in understanding the technical solution of the present invention, and does not mean that the above content is admitted as prior art. Contents of the invention [0004] The main purpose of the present inven...
