Analysis and Control of Unknown In-vehicle Network System

摘要

A CAN-Bus protocol analysis and verification method with three key aspects which are static analysis, dynamic analysis and verification & control is put forward. Static analysis ascertains the communication information of each node by bus residual method; Synchronous contrast method is put in use to obtain practical and effective control protocol in the dynamic analysis; Verification & control is to verify the correctness of the analytical protocol and to achieve the control of the critical subsystems by bus gateway system. This scheme has been used to analyze a foreign parallel hybrid powertrain system, and it proves the correctness of the designed static analysis and dynamic analysis, the applicability of verification & control.
