New energy vehicle central control system safety inspection method

Abstract

A safety inspection method for a central control system of a new energy vehicle, comprising: S1, pre-storing a personalized identification scheme and identity information corresponding to a user in the central control ECU of the new energy vehicle; S2, passing identity recognition before the user uses the new energy vehicle The information identifies the user's identity, matches the corresponding personalized identification scheme according to the identification result, and initializes the step level in the ECU; S3. During the driving process of the new energy vehicle, collects the vehicle driving control information and sends it to the ECU, and the ECU passes the personalized identification scheme Judging whether the vehicle driving control information is abnormal, jump to step S5 when abnormality occurs, otherwise jump to step S4; S4, judge the safety of the ECU through the safety identification model, and jump to step S3 when it conforms to the safety identification model and Execute until the new energy vehicle stops running, otherwise jump to step S5; S5, reduce the step level in the ECU, and judge whether the safe driving level in the ECU reaches the minimum step level.

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...
