Abstract

The invention provides an automobile gateway firewall message health check method and device and an automobile, and the method comprises the following steps: receiving a CAN message, and generating aninterrupt signal according to the CAN message; acquiring a mailbox index number of an interrupted mailbox according to the interrupt signal; acquiring position information, length information and a preset standard signal value corresponding to each signal of the CAN message according to the mailbox index number; acquiring a signal value of each signal of the CAN message according to the positioninformation and the length information of each signal; carrying out comparative analysis on each signal value and a corresponding preset standard signal value; and determining whether the signal valueof the CAN message is valid or invalid according to the comparative analysis result. The device is used for implementing the method, and the automobile comprises the device. According to the method disclosed in the invention, the performance requirement of the CAN message health check function on the gateway chip is greatly reduced, and the protection capability of the gateway firewall on the CANbus is improved.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a signal indexing method and device for gateway firewall health check, and a vehicle. Background technique [0002] With the development of intelligent network connection, the problem of vehicle network security has become increasingly prominent. On the one hand, there are more and more external interfaces of vehicles (such as OBD, Wi-Fi, 4G, etc.), while providing rich applications, there are also more and more risk sources; on the other hand, more functions have been added to the in-vehicle network And options make the in-vehicle network more complex, and the security of the in-vehicle network is also increasingly valued by the industry. [0003] Hundreds of different CAN messages are running at high frequency on the CAN bus (Controller Area Network Bus) of the car, and the signals between each ECU (Electronic Control Unit, electronic control unit) in the car text transmissi...
