Zusammenfassung: | The invention provides a sensor system with a fault diagnosis function. The sensor system comprises a combination instrument assembly, a sensor assembly, a vehicle-mounted diagnosis instrument and a TBOX; a diagnosis circuit is arranged in the combination instrument assembly, and the diagnosis circuit is used for monitoring the line connection state of the sensor assembly in real time; and the combination instrument assembly is configured to broadcast fault information diagnosed based on a monitoring signal of the diagnosis circuit to the TBOX and the vehicle-mounted diagnosis instrument through a whole vehicle CAN line. The fault information of the sensor system can be quickly and accurately diagnosed, the maintenance cost of a user is reduced, and the maintenance efficiency and the maintenance accuracy are improved.
