The invention discloses a vehicle ramp sliding shutdown control method and electronic equipment. The vehicle ramp sliding shutdown control method comprises the steps of firstly, acquiring the acceleration comprehensive value of a vehicle on a current ramp, the gravitational acceleration of the vehicle and the driving acceleration of the vehicle on the current ramp; and calculating the slope angleof the current ramp according to the acceleration comprehensive value, the gravitational acceleration and the driving acceleration, and controlling the vehicle to drive according to the slope angle. The slope angle of the current ramp is calculated by combining the acceleration comprehensive value sent by the VDC or the ESP, the gravitational acceleration of the vehicle and the driving acceleration of the vehicle on the current ramp, the interference of the acceleration of the vehicle moving superimposed on the ramp direction on the slope angle calculation is eliminated, and the slope angle information can be accurately calculated; the vehicle is controlled to run according to the calculated slope angle, an engine can be controlled to stop at a proper slope, and the problems of vehicle sliding and the like caused by improper stop positions are avoided.
