Abstract

The embodiment of the specification discloses a vehicle creep control method, device, electronic equipment and computer storage medium. The method includes: according to the current vehicle speed and the target vehicle speed, determining the basic creep torque corresponding to the current vehicle speed; obtaining the corresponding brake master cylinder pressure when the brake pedal of the vehicle is depressed at the current vehicle speed; according to the The brake master cylinder pressure and the basic creep torque determine the braking compensation torque corresponding to the current vehicle speed; according to the basic creep torque and the braking compensation torque, determine the braking creep corresponding to the current vehicle speed row torque. The embodiments of the present specification can improve the stability of the vehicle at low speed when the vehicle is braking and creeping at low speed.

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 ...
