Embodiment Construction

[0062] Such as figure 1 As shown, in an embodiment of the present invention, a new energy vehicle central control system security inspection method, which includes the following steps:

[0063] S1. Behavior model, feature model, judgment model and state monitoring model in the ECU of the vehicle central control system;

[0064]S2. When the ECU receives the vehicle control command, judge the safety level of the vehicle control command through the judgment model. When the safety level exceeds the preset level, jump to step S3; the security level can be set independently. For example, some vehicle control commands are only for Obtaining the location and driving status information of the vehicle is not executable, so it is not harmful to the normal driving of the car. Some commands are for controlling the multimedia system of the vehicle, which can also be classified as a lower security level. Therefore, through this step, some control instructions that have a very low impact on...

Abstract

The invention provides a new energy vehicle central control system safety inspection method which comprises the steps of (S1) setting a behavior model, a feature model, a judgment model and a state monitoring model in a vehicle central control system ECU, (S2) judging the safety level of the vehicle control command by the judgment model when the ECU receives a vehicle control command, and jumpingto the step (S3) when the safety level reaches a preset level, (S3) judging whether the vehicle control instruction belongs to the remote control command and jumping to step (S4) is so, otherwise, jumping to step (S6), (S4) judging whether the vehicle control instruction is legal according to the behavior model, and jumping to step S5 if so, otherwise, jumping to step (S7), (S5) obtaining currentvehicle state information through the state monitoring model, sending current vehicle state information and the remote control command to a pre-defined sandbox in the ECU for vehicle state simulationand judging whether a vehicle state simulation result conforms to the feature model.

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. More and more functions are handled by the central control system ECU of the vehicle, and some vehicles have realized the function of remote control. But on the other hand, the safety of the car is reduced. Once a criminal remotely controls the vehicle, the life safety of the user will be 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 method for a central control system of a new energy vehicle, comprising the steps of: [0005] S1. Behavior model, feature model, judgment model and state monitoring model in the ECU of the ...
