1. A parking method, wherein the parking method is applied to a vehicle having a hydraulic braking system, and the method comprises:
by one or more processors, when the vehicle satisfies a one-pedal activating condition, controlling the vehicle to enter a one-pedal-function activating mode;
by one or more processors, 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;
by one or more processors, based on the current-vehicle-speed information and the road-slope information, calculating to obtain a parking torque;
by one or more processors, acquiring a first torque difference between the parking torque and the first electric-motor recovering torque; and
by one or more processors, performing pressure buildup to the vehicle based on the first torque difference, to control the vehicle to complete a parking operation,
wherein the satisfying the parking-controlling-function activating condition at least comprises: the accelerator-pedal depth being less than a depth calibration value; the accelerator pedal being not trodden within a pedal-continuation calibration duration or the brake-master-cylinder pressure value of the accelerator pedal being less than a pressure calibration value within a continuation calibration duration.
