Abstract

A method for parking control is provided in the present application, which includes the following steps: determining whether a single-pedal mode is activated; determining whether conditions for deceleration control are met when the single-pedal mode is activated; controlling the new-energy vehicle to decelerate when the conditions for deceleration control are met; determining whether conditions for sending a brake request to a motor controller are met during a process of controlling the new-energy vehicle to decelerate; sending the brake request to the motor controller when the conditions for sending a brake request to the motor controller are met; and sending a parking request to an electronic handbrake when the new-energy vehicle is in the brake mode and the speed of the new-energy vehicle is smaller than the third preset value for a third preset time, enable the new-energy vehicle to enter in a parking mode.
