The embodiment of the invention provides a control method and device for preventing an automobile from sliding on a slope. According to the control method, the current road slope angle is calculated through a longitudinal acceleration signal of an automobile and the speed of the automobile, and when the current road slope angle is larger than a threshold value, a first additional torque is calculated according to the current road slope angle, and the first additional torque is output to a driving motor, so that a vehicle control unit can accurately identify the road slope, control the output of the vehicle driving torque according to the actual road condition, and the safety and comfort of the vehicle is ensured at the same time.
