DUPLEXING APPARATUS AND A METHOD OF AN ELECTRONIC CONTROL SYSTEM IN AN AUTOMOBILE, CAPABLE OF PROTECTING A DRIVER FROM ACCIDENTS BY IMMEDIATELY HANDLING ERRORS

摘要

PURPOSE: A duplexing apparatus and a method of an electronic control system in an automobile are provided to immediately deal with errors in case the errors occur in an electronic control unit(ECU) of the automobile including complex electronic parts and software by dualizing the electric control unit.;CONSTITUTION: A dualizing apparatus of an electronic control system in an automobile includes a plurality of electronic control units(100,200) which are dualized into an active state and a standby state according to a unique ID which is connected to various sensors and an actuator(10). The electronic control unit of the standby state monitors an unusual condition by outputting a request message to the electronic control unit of the active state. The electronic control unit of the standby state is converted into the active state when errors are detected. The electronic control units receive a signal from the sensors and the actuator and receive a message from other electronic control units at the same time.;COPYRIGHT KIPO 2010
