Abstract

The invention relates to a dual MCU control system applied to an automobile electronic parking brake. The dual MCU control system is characterized by comprising a microcontroller MCU1#, a microcontroller MCU2#, a control switching circuit, H-Bridge driving circuit, a parking switch circuit and a biaxial acceleration sensor; the microcontroller MCU1# and the microcontroller MCU2# are the core modules of an electronic parking brake control system, and the microcontroller MCU1# and microcontroller MCU2# implement the control switching circuit to realize the control over a parking motor by detecting the parking switch circuit and biaxial acceleration sensor signals; and the dual circuit MCU system is the core of the control system, can independently control a drive circuit to realize the control over an electronic parking brake motor, can switch to the other circuit to continue to control after one of MCU circuits fails to control, realizes redundant backup of the control system, obtain better system backup, and realizes high safety and high reliability of the system.

Description

technical field [0001] The invention relates to the field of automotive electronic parking brake control systems, in particular to a dual-MCU control system applied to automotive electronic parking brakes. Background technique [0002] The dual MCU control system applied to the electronic parking brake of the car is mainly composed of the microcontroller MCU1 # , Microcontroller MCU2 # , control exchange circuit, H-Bridge drive circuit, parking switch circuit and biaxial acceleration sensor. Microcontroller MCU1 # , MCU2 # It is the core control module of the electronic parking brake system. In the automotive electronic parking brake system, a single MCU is used as the mainstream control device, and there is a certain risk of failure, which may affect the safety of the automotive parking brake. Because the present invention adopts dual MCUs as the control core, after a single MCU fails, the backup MCU can still be used to realize the parking brake control through the c...
