Abstract: A parking method and apparatus. The method comprises: when a vehicle satisfies a one-way pedal enabling condition, controlling the vehicle to enter a one-way pedal function enabling mode (101); when the vehicle enters the one-way pedal function enabling mode and satisfies a parking control function enabling condition, obtaining the current vehicle speed information, road slope information, and a first motor recovery torque (102); on the basis of the current vehicle speed information and the road slope information, obtaining a parking torque by calculation (103); obtaining a first torque difference between the parking torque and the first motor recovery torque (104); and performing voltage build-up on the vehicle on the basis of the first torque difference, and controlling the vehicle to complete a parking operation (105). In this way, even if an electric drive system of the vehicle loses the recovery capability under the condition that a battery is fully charged, etc., the vehicle can be performed brake compensation by means of voltage build-up, and is controlled to complete the parking operation, which can improve the braking effect of the vehicle and ensure the driving consistency.
