The invention relates to a safety guarantee system applied to an automatic driving vehicle, the system comprises a sensor abstraction, an automatic driving function module, a safety diagnosis module and an actuator abstraction, the sensor abstraction comprises a laser radar abstraction, a camera abstraction, a millimeter wave radar abstraction and a combined positioning abstraction, the automatic driving function module comprises a sensing module, a planning module, a decision module and a control module, and the safety diagnosis module comprises an abstract state monitoring module, a function module state monitoring module, a chassis state monitoring module, an operating system state monitoring module, an exception handling module and a data storage module. By means of the designed safety guarantee system, it can be ensured that when the abstraction state of the sensor, the abstraction state of the automatic driving function module and the abstraction state of the actuator are abnormal, the driving safety of the automatic driving vehicle is not affected, and the situation that the vehicle is out of control due to the abnormal chassis state and operating system of the automatic driving vehicle can be avoided; and the effect of improving the safety and reliability of the vehicle is achieved.
