Abstract

The invention relates to an EPB emergency backup control system and a control method. The control system includes a vehicle controller, a vehicle body stability control unit, an EPB control switch, an electronic shifter, an instrument and a parking actuator, and is characterized in that the body stability control unit is a caliper The clamping state signal output terminal is connected to the signal input terminal of the vehicle controller, the emergency backup braking request signal output terminal of the vehicle controller is connected to the signal input terminal of the parking actuator, and the instrument reminder information output of the vehicle controller The terminal is connected with the signal input terminal of the instrument. The control method is: when performing EPB active parking, if the VCU detects that the left and right calipers are not clamped at the same time, the instrument will immediately remind the driver to long pull the EPB switch or P switch to enter the EPB emergency backup control state, and confirm the calipers state again. If it is still not clamped at the same time, the VCU will control the clamping of the unilateral caliper to ensure successful parking and meet the performance requirements for parking on slopes. The invention has low cost and large profit.

Description

technical field [0001] The invention relates to parking, in particular to an EPB emergency backup control system and control method. Background technique [0002] With the development of automobile technology, more and more new energy vehicles tend to cancel the P gear locking mechanism. In order to meet the requirements of the braking and parking performance regulations, the EPB electronic parking brake system is equipped and the P gear is canceled at the same time. On models with a locking mechanism, a brake backup control system is required. When the EPB control system fails, the brake backup control system ensures that the vehicle can still meet the parking requirement of 8% full load. [0003] One technical solution is to use an independent EPB dual redundant controller, which is a dual power supply control system, a dual CAN network, and the left and right caliper motor control circuits are completely independent to achieve mutual backup control, that is, if one calip...
