Beschreibung
Zusammenfassung:	The present invention discloses an automobile electronic parking execution controller with a double-MCU redundancy design, relates to the technical field of electrical automobile control, and solves the problems that since a single MCU is used as a mainstream control device, there are certain crash fault and failure risks, which may affect the safety of an automobile parking brake. The automobile electronic parking execution controller 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. The following effect is achieved: 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.
