Abstract

The invention relates to an electronic parking control system and a control method thereof. The electronic parking control system is suitable for an automobile, and the automobile comprises a whole vehicle VCU, a storage battery, a left caliper, a right caliper and an EPB / EPBi / ESC related controller. The electronic parking control system mainly comprises a master control MCU module, a first relay module, a second relay module, a pre-driving module, a first H-bridge module and a second H-bridge module, wherein the master control MCU module is used for receiving instructions sent by the whole vehicle VCU. According to the electronic parking control system and the control method thereof, the overall circuit is compact, the purpose of double-circuit backup parking is achieved, and the parking performance can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of motor vehicle brake system control, in particular to an electronic parking control system and a control method thereof. Background technique [0002] With the development of automobiles and automatic driving, the automotive industry has higher and higher requirements for ISO26262 functional safety, and puts forward higher requirements for the reliability and safety of automobiles. For this reason, adding failure backups to various controllers will be a future trend . For the electronic parking control system, although there is a P file lock as a backup, the P file lock can only be used to keep the vehicle stationary on a slope of 8%, and cannot meet the requirements of a higher slope. With the development of automatic driving, higher requirements will inevitably be put forward for electronic parking backup. Therefore, developing a new technology or system to improve parking safety is the direction of fut...
