Automatic parking method and system applied to commercial vehicle and vehicle

The invention discloses an automatic parking method and system applied to a commercial vehicle and a vehicle, and relates to the technical field of automatic parking. The automatic parking method comprises the steps that gravity information and vehicle speed information on a driver seat are collected; when it is judged that the gravity information and the vehicle speed information are both smaller than the preset threshold value, a corresponding control instruction is sent to a manual control electromagnetic integrated valve in the braking system; and the manual control electromagnetic integrated valve pulls up a hand brake after receiving the control instruction so as to brake the vehicle. The state of a driver and the state of the vehicle are obtained through the gravity sensor and the vehicle speed sensor, a traditional manual control valve is replaced with the manual control electromagnetic integrated valve, and therefore manual and automatic parking integration is achieved, and serious accidents caused b
