| description | The present disclosure provides a parking method and apparatus, which is applied to a vehicle having a hydraulic braking system, and relates to the technical field of vehicle driving. The method includes: when the vehicle satisfies a one-pedal activating condition, controlling the vehicle to enter a one-pedal-function activating mode (101); 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 (102); based on the current-vehicle-speed information and the road-slope information, calculating to obtain a parking torque (103); acquiring a first torque difference between the parking torque and the first electric-motor recovering torque (104); and performing pressure buildup to the vehicle based on the first torque difference, to control the vehicle to complete a parking operation (105). Accordingly, even if the electric driving system loses the recovery ability under the condition of full battery power, the vehicle may also perform braking compensation to the vehicle by means of the pressure buildup, to control the vehicle to complete the parking operation, i.e., to enable the vehicle to complete the brake-stopping, which can improve the effect of the brake-stopping of the vehicle, and ensure the drive uniformity. |
