Abstract
A system and method for detecting a faulty electronic control unit (ECU) on a vehicle network are disclosed. The system includes a monitoring controller configured to detect an identification (ID) of a controller area network (CAN) message first transmitted on a vehicle network and transmit the ID of the CAN message to a gateway controller. The gateway controller performs a wake-up when a vehicle engine is turned off, enables the monitoring controller and detects an ECU corresponding to the ID of the CAN message as the faulty ECU.
Claims18
A detection system for detecting a faulty electronic control unit (ECU) on a vehicle network, the detection system comprising:
- a monitoring controller configured to detect an identification (ID) of a controller area network (CAN) message first transmitted on a vehicle network;
- and
- a gateway controller configured to perform a wake-up when a vehicle engine is turned off, to enable the monitoring controller, and to detect an ECU corresponding to the ID of the CAN message as the faulty ECU of a plurality of ECUs on the vehicle network.
A method of detecting a faulty electronic control unit (ECU) on a vehicle network, the method comprising:
- performing a wake-up of a gateway controller when a vehicle engine is turned off;
- enabling, by the gateway controller, a monitoring controller;
- detecting, by the monitoring controller, an identification (ID) of a controller area network (CAN) message first transmitted on a vehicle network;
- and
- detecting an ECU corresponding to the ID of the CAN message as the faulty ECU of a plurality of ECUs on the vehicle network.
