LIN ECU Method of automatically restarting ecu upon occurrence of lin communicatin errors

摘要

The present invention automatically restarts the ECU according to the occurrence of a LIN communication error that automatically checks the ECU according to the communication error of the LIN communication used when the control signal of the body control module is transmitted to the ECU, and automatically reboots to remove the error. The present invention relates to a method by detecting an error in a control signal transmitted through a LIN (Local Interconnect Network) communication cable connecting a body control module (BCM) and an electronic control unit (ECU) to an electronic control unit (ECU). ), including a method of restarting the ECU (Local Interconnect Network) provided in the ECU (Local Interconnect Network) transceiver, transmits the control signal of the vehicle body control module to μC (micro controller) and transmits it through the driving terminal to do; When the micro controller (μC) is operated with an operation signal transmitted through the driving terminal of the micro controller (μC), a carrier signal according to the transmission signal of the control signal transmitted through the transmission terminal is transmitted to the transmission terminal of the micro controller (μC). transmitting to the receiving terminal of the LIN transceiver through Check whether the transmission signal of the LIN transceiver is normal by checking the transmission signal transmitted from the LIN transceiver with the μC (micro controller) in the μC (micro controller) to check whether the μC (micro controller) is normal or the μC (micro controller) ) of the vehicle body control module to check whether μC is normal, and if the transmission signal transmitted to μC checked by the vehicle body control module or the carrier signal returned from μC is abnormal in the normal state, μC is included. It characterized in that it comprises the step of rebooting the ECU.
