Abstract

The invention discloses an electronic parking controlling system with a redundant parking function. The electronic parking controlling system comprises an EPB electronic controlling unit and a caliperactuator. The EPB electronic controlling unit comprises an electronic parking controlling module and a power supply management circuit. The parking controlling system is internally provided with a redundant parking controlling unit. The redundant parking controlling unit comprises an EPB switch, a gradient sensor module and a motor driving module which are in the EPB electronic controlling unit,and is further provided with a redundant parking controlling module and a redundant module power supply management circuit. The redundant parking controlling module is connected with the electronic parking controlling module through a plurality of signal lines. By means of the technical scheme, not only can the normal parking function and the emergency braking function be met, but also the P-gearlocking mechanism function of an automatic gearbox can be replaced, the safety of parking is improved, and the electronic parking controlling system has the advantages of low cost, convenient arrangement and the like.

Description

technical field [0001] The invention belongs to the technical field of motor vehicle braking system control. More specifically, the present invention relates to an electronic parking control system with redundant parking functions. In addition, the present invention also relates to a control method of the parking control system. Background technique [0002] The national standard GB21670 stipulates that for a passenger car equipped with an electronic parking control system (referred to as "EPB"), when the wiring harness or controller other than the power line fails, the vehicle can still park with a full load on an 8% slope. For this reason, for vehicles equipped with a parking gear (P gear) locking mechanism, when the vehicle is in P gear, the internal locking mechanism locks the gearbox. [0003] With the wide application of EPB, the EPB electronic control unit controls the caliper actuator to realize the parking function, and the single-side electronic parking mechanism...
