Steering system S and C automatic rating device and method based on functional safety

The invention provides a steering system S and C automatic rating device and method based on functional safety. The method comprises the steps that S1, a hazardous event is defined; s2, inputting scene parameters, wherein the scene parameters refer to the fact that dynamic behaviors of traffic participants in the driving scene are set to be corresponding numerical values; s3, calculating a relative collision speed; s4, carrying out severity grade evaluation; s5, calculating collision time; s6, performing controllability grade evaluation; and S7, generating a severity and controllability analysis table for each hazardous event. The steering system S and C automatic rating method based on functional safety has the advantages that a reference basis is provided for evaluation of the automobile safety integrity level (ASIL level) of the steering system, and support of test scene data is provided for a whole automobile level functional safety test. 本发明提供了一种基于功能安全的转向系统S和C自动评级装置及方法，S1、定义危害事件；S2、输入场景参数，所述场景参数指驾驶场景中交通参
