The invention relates to a new energy automobile parking control method and device, computer equipment and a storage medium. The method comprises the steps that a vehicle control unit samples power data of a vehicle, and the power data including the longitudinal acceleration, the rotating speed of a front motor, the rotating speed of a rear motor and the current vehicle speed are obtained; the current gradient information of the automobile is calculated according to the automobile power data, the parking feed-forward torque is calculated according to the gradient information, the parking feed-forward torque is adjusted and corrected, and the parking adjusting torque is obtained; and the parking demand torque is calculated according to the parking feedforward torque and the parking adjusting torque, and a motor is controlled to output the torque according to the parking demand torque so as to control the torque when the automobile is parked. By adopting the method, the torque output can be controlled through the sampled power data, so that the parking process of the automobile is controlled, and the safety of the automobile is improved.
