AUTOMOBILE ELECTRONIC PARKING EXECUTION CONTROLLER WITH DOUBLE-MCU REDUNDANCY DESIGN

An automobile electronic parking execution controller with a double-MCU redundancy design comprises a parking switch circuit, a biaxial acceleration sensor unit, a main micro control unit (MCU) U and a monitoring MCU U wherein the main MCU U controls a parking motor by means of detecting signals of the parking switch circuit and the biaxial acceleration sensor, the monitoring MCU U monitors a running state of a whole control system and restores the main MCU U when the main MCU U is abnormal, and the main MCU U restores the monitoring MCU U when the monitoring MCU U is abnormal. After the main MCU U crashes, the main MCU U can still be quickly stored through the monitoring MCU U so that the main MCU U quickly enters a response state to recover the parking brake control ability, which improves the safety of the system.
