The invention provides a parking control method and device, computer equipment and a storage medium. The method comprises the steps that a vehicle control unit monitors data information including the vehicle longitudinal acceleration, the state of an electronic stability controller and the rotating speed of a motor; when the vehicle control unit recognizes that the function of the self-adaptive cruise control system is activated but the parking function of the electronic stability controller is abnormal and fails, the vehicle control unit calculates the current vehicle speed based on the rotating speed of the motor and calculates the vehicle acceleration based on the current vehicle speed; automobile parking basic torque is calculated according to the automobile acceleration and the automobile longitudinal acceleration, and the parking basic torque is adjusted and corrected to obtain parking adjusting torque; and the braking parking demand torque is calculated according to the parking basic torque and the parking adjusting torque, and the vehicle control unit controls motor torque output according to the braking parking demand torque so as to control auxiliary braking parking of the vehicle self-adaptive cruise system. According to the invention, the torque output of the motor can be controlled, and the brake parking function of the ACC system can be realized.
