4. Operating Principle
After power-on, the Autoliv Gtw.Mod. B0110 gateway module completes self-inspection, bus handshake and protocol initialization. As the core communication hub of the vehicle safety electronic network, it collects and analyzes bus messages from each electronic control unit, filters and corrects abnormal data, and completes protocol conversion and data sorting.
According to the vehicle safety system timing logic, the module forwards valid data accurately to realize two-way real-time data synchronization between the airbag control unit, body ECU and main control system. During operation, it continuously monitors bus voltage, message status and link quality. Once faults such as short circuit, communication timeout and data disorder are detected, it triggers isolation self-protection, records fault codes and reports to the vehicle system.
Through bus isolation and fault interception mechanisms, it effectively prevents overall vehicle communication disorder caused by single-point faults, ensures the stable operation of vehicle passive safety systems such as airbags under full driving conditions, and guarantees driving safety reliability.
