Safety inspection method for central control system of new energy vehicle

Abstract

The invention provides a safety inspection method for a central control system of a new energy vehicle. The safety inspection method comprises the following steps that S1, a corresponding personalized recognition scheme and identity recognition information of a user are pre-stored in a central control ECU of the new energy vehicle; S2, the identity of the user is recognized through the identity recognition information before the user uses the new energy vehicle, the corresponding personalized recognition scheme is matched according to the recognition result, and the step level is initialized in the ECU; S3, during the running process of the new energy vehicle, automobile driving control information is acquired and sent to the ECU, the ECU judges whether the automobile driving control information is abnormal or not through a personalized recognition scheme, and skip to the step S5 when the automobile driving control information is abnormal, otherwise skip to the step S4; S4, the ECU safety is judged through a safety identification model, jump to the step S3 when the safety recognition model is met, and execute until the new energy vehicle stops running, and otherwise, jump to the step S5; and S5, the step level in the ECU is reduced, and whether the safe driving grade in the ECU reaches the lowest step grade or not is judged.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to a safety inspection method for a central control system of a new energy vehicle. Background technique [0002] Existing new energy vehicles are different from traditional vehicles, and more and more functions are handled by the central control system ECU of the vehicle. Since the functions of the current ECU are becoming more and more complex, and the system resources occupied by various functions will be more and more, on the premise that the ECU is responsible for the vehicle control function, once the ECU central control system has a safety hazard, it will make the safety of the car The degree of security is reduced, and the life safety of users is seriously threatened. Contents of the invention [0003] In view of this, the present invention provides a safety inspection method for a central control system of a new energy vehicle. [0004] A safety inspection m...
