The invention discloses an automobile safety integrity level evaluation method, device, equipment and medium, the automobile safety integrity level evaluation method comprises the following steps: obtaining driving data in a target driving scene, the driving data comprising motion state data of a front automobile and a rear automobile when a fault event occurs; determining the maximum perceptual hazard time of the driver of the rear vehicle under the condition that the front vehicle and the rear vehicle reach the target critical collision condition by using the driving data; determining a controllability level corresponding to the target driving scene by using the maximum perceptual hazard time of the driver of the rear vehicle; and evaluating an automobile safety integrity level corresponding to the target driving scene by using the controllability level, the severity level and the exposure level corresponding to the target driving scene. Through the above mode, the accuracy of evaluating the automobile safety integrity level can be improved.
