The invention provides an electronic parking control system of an electric vehicle, which comprises an EPB module, a vehicle main controller, a peripheral control circuit, a right parking motor and a left parking motor, after the vehicle is started, self-inspection is carried out, when abnormity is found during self-inspection, the vehicle cannot run and cannot be dragged, a trailer button on the EPB module is shifted to a trailer position, the EPB module loosens the electronic parking, and the EPB module stops the electronic parking. The vehicle can be normally dragged, the EPB module sends a signal to the vehicle main controller at the same time, the vehicle main controller cannot drive the vehicle to run, the vehicle is dragged to a maintenance center to be maintained, after maintenance succeeds, the gear of the EPB module is shifted to the running gear, the vehicle is restarted, and at the moment, the vehicle can execute running logic when self-inspection is normal. Through the design of the electronic parking control system, the structural composition and the control logic of the system are simplified, and when the electronic parking control system is abnormal, the maintenance of the trailer is not influenced on the premise of ensuring the parking safety.
本发明提供了一种电动车的电子驻车控制系统,包括:EPB模块、车辆主控制器、外围控制电路、右驻车电机和左驻车电机,车辆启动后进行自检,当自检时发现异常,车辆无法运行且无法被拖动,将EPB模块上的拖车按钮拨到拖车位,EPB模块将电子驻车松开,车辆可以被正常拖动,EPB模块同时发送信号至车辆主控制器,车辆主控制器将不能再驱动车辆运行,将车辆拖至维修中心对车辆进行维修,维修成功后,再将EPB模块的档位拨到运行档,车辆重启,此时车辆可再执行自检正常时的运行逻辑。本发明通过对电子驻车控制系统的设计,简化了系统结构组成和控制逻辑,当电子驻车控制系统发生异常时,可以在保证驻车安全性的前提下,也不影响拖车维修。
