The invention provides a vehicle control method. The vehicle control method comprises the steps that a delivery location and an environment file are received; the delivery location and the environmentfile are invoked, and delivery path data is generated; obstacle information is generated, and decision result information is generated according to the delivery path data, the obstacle information and the location information; torque control information after conversion process is sent to a motor controller to control the speed of a vehicle, and steering control information after the conversion process is sent to an EPS to control steering of the vehicle; a second operation command is sent to a vehicle body controller so that the body controller can generate a driving signal according to a control signal of an LED, and the LED is driven to convert electric energy into light energy according to the driving signal; when the vehicle reaches a first location in the delivery location, a picking code is received and a cabinet lock number is determined, and the vehicle body controller drives a cabinet lock to open according to the cabinet lock number. And thus, high-precision control over avehicle control unit is achieved, and the emergency response capability is high when dealing with an emergency.
