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) U2 and a monitoring MCU U1, wherein the main MCU U2 controls a parking motor by means of detecting signals of the parking switch circuit and the biaxial acceleration sensor, the monitoring MCU U1 monitors a running state of a whole control system and restores the main MCU U2 when the main MCU U2 is abnormal, and the main MCU U2 restores the monitoring MCU U1 when the monitoring MCU U1 is abnormal. After the main MCU U2 crashes, the main MCU U2 can still be quickly stored through the monitoring MCU U1, so that the main MCU U2 quickly enters a response state to recover the parking brake control ability, which improves the safety of the system.
