Title:
AUTOMOBILE ELECTRONIC PARKING EXECUTION CONTROLLER HAVING DOUBLE-MCU REDUNDANCY DESIGN
Document Type and Number:
WIPO Patent Application WO/2022/028520
Kind Code:
A1
Abstract:
An automobile electronic parking execution controller having a double-MCU redundancy design. The controller comprises a parking switch circuit, a double-axis acceleration sensor unit, a main MCU U2 and a monitoring MCU U1. The main MCU U2 controls a parking motor by detecting signals of the parking switch circuit and the double-axis acceleration sensor; the monitoring MCU U1 monitors a running state of the whole control system and resets the main MCU U2 when the main MCU U2 is abnormal; and when the monitoring MCU U1 is abnormal, the main MCU U2 resets the monitoring MCU U1. The electronic parking execution controller having the double-MCU redundancy design achieves the effects that after crash of the main MCU U2 occurs, the main MCU U2 can still be rapidly reset by monitoring the MCU U1, so that the main MCU U2 rapidly enters a response state, the parking brake control capability is recovered, and the system safety is enhanced.
