The invention discloses a one-key emergency stop system for an automatic driving vehicle. The system comprises a one-key stop button and a pressure control system. The one-key stop button is in signalconnection with the pressure control system, and the pressure control system is in signal connection with an automatic driving vehicle. The system is based on a one-key parking principle of applyingbrake pressure; a resettable switch button is used as an emergency stop button; a pressure control system is triggered based on a high-level signal, a user presses down a stop switch button, and thenthe pressure control system applies a certain braking pressure to a vehicle to achieve emergency braking of the vehicle. And when the user releases the stop switch button, the vehicle enters the driving mode again after the brake pressure disappears, that is, the automatic driving function does not need to be restarted when the automatic driving vehicle is restarted.

本发明公开了一种自动驾驶车辆一键紧急停车系统，包括一键停车按钮和压力控制系统，所述一键停车按钮信号连接于所述压力控制系统，所述压力控制系统信号连接有自动驾驶车辆。本发明通过基于施加制动压力的一键停车原理；采用可复位的开关按钮作为急停按钮；基于高电平信号触发压力控制系统，用户按下停车开关按钮，然后压力控制系统对车辆施加一定大小的制动压力实现车辆紧急制动。当用户释放停车开关按钮，制动压力消失车辆重新进入驾驶模式，即自动驾驶车辆重新起动时不需要再次启动自动驾驶功能。
