Abstract: The method includes: when the vehicle satisfies a one-pedal activating condition, controlling the vehicle to enter a one-pedal-function activating mode; when the vehicle enters the one-pedal-function activating mode and satisfies a parking-controlling-function activating condition, acquiring current-vehicle-speed information, road-slope information and a first electric-motor recovering torque; based on the current-vehicle-speed information and the road-slope information, calculating to obtain a parking torque; acquiring a first torque difference between the parking torque and the first electric-motor recovering torque; and performing pressure buildup to the vehicle based on the first torque difference, to control the vehicle to complete a parking operation.

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.
