Abstract

The invention relates to an EPB backup system. The EPB backup system is characterized by comprising a vehicle electronic control module, a controller local area network bus, a main battery, an integrated electronic parking system EPBi, an EPB switch, EPB clamps, an EPB standby controller, an ignition switch IGN, a standby battery and a car P gear signal source. In the scheme, a standby EPB is introduced on the basis of an original independent electronic parking brake system; power is supplied by the standby battery, the fault of the independent electronic parking brake system can be monitoredin real time, an intervention measure can be taken when the independent electronic parking brake system fails, with the P gear as a parking input instruction, the left and right EPB clamps are effectively controlled, and the safety performance of the independent electronic parking brake system is further improved.

Description

technical field [0001] The invention relates to the field of electronic parking brakes, in particular to an EPB brake backup system. Background technique [0002] The independent electronic parking system (Integrated Electric Park Brake) of the upgraded version of the traditional EPB integrates the two separate electronic control units of the original EPB by integrating with the newly designed electronic stability control system (Electronic Stability Control, ESC). While keeping the original EPB functions unchanged, many ESC functions have been added, and at the same time, system complexity, weight and installation costs have been reduced, providing OEMs with more cost advantages. The original EPB system integrated the EPB module into other modules, which improved the overall unity of the system and saved cost and space. However, as a safety module, the EPB may not be able to realize the emergency function triggered by the failure of other modules due to the failure of othe...
