Abstract

The embodiments of the invention disclose a vehicle crawling control method and device, electronic equipment, and a computer storage medium. The method includes the steps that a basic crawling torquecorresponding to a current vehicle speed is determined according to the current vehicle speed and a target vehicle speed; a corresponding brake master cylinder pressure is acquired when a brake pedalof a vehicle is pressed at the current vehicle speed; a brake compensation torque corresponding to the current vehicle speed is determined according to the brake master cylinder pressure and the basiccrawling torque; and according to the basic crawling torque and the brake compensation torque, the brake crawling torque corresponding to the current vehicle speed is determined. According to the embodiment of the vehicle crawling control method and device, the electronic equipment, and the storage medium, the stability of low-speed running of the vehicle can be improved under the condition thatthe vehicle crawls during low-speed braking.

Description

technical field [0001] This specification relates to the field of vehicle control, in particular to a vehicle creep control method, device, electronic equipment and computer-readable storage medium. Background technique [0002] With the popularization of electric vehicles and people's pursuit of car driving performance, cars are required to be able to automatically run smoothly at low speeds in certain working conditions, such as following cars at low speeds in traffic jams, parking at low speeds in garages, and going up and down slopes at low speeds. [0003] However, the existing vehicle creep control methods are mainly aimed at automatically controlling the vehicle to run at a stable speed after the driver releases the accelerator pedal at low speeds. When the vehicle is crawling at a low speed, when the driver actively brakes the vehicle by stepping on the brake pedal, it will cause the driver to repeatedly operate the accelerator pedal and the brake pedal, causing the ...
