The invention discloses a new energy automobile electronic parking control system. When an ESC works normally and a VECU receives an ESM parking request of a driver, the VECU sends a parking request to the ESC, the ESC enables two EPB motors to realize parking, and the VECU receives parking state information fed back by the ESC and confirms that parking is completed; and when the ESC breaks down, the VECU makes judgment, and one EPB motor is directly controlled by controlling the two relays to achieve parking control. According to the new energy automobile electronic parking control system, through a set of hardware equipment, the VECU enables the EPB locking mechanism in a direct and indirect mode to achieve the electronic parking function, the cost is low, an abnormal sound does not exist, and meanwhile safety guarantee is achieved.

    本发明公开了一种新能源汽车电子驻车控制系统,当ESC正常工作,VECU收到驾驶员ESM驻车请求时,VECU向ESC发送驻车请求,ESC控制两路EPB电机实现驻车,VECU收到ESC反馈的驻车状态的信息,确认驻车完成;当ESC发生故障时,VECU进行判断,通过控制两个继电器直接控制一路EPB电机实现驻车控制。本发明中的一种新能源汽车电子驻车控制系统,通过一套硬件设备,VECU使用直接和间接的方式控制EPB锁止机构实现电子驻车功能,成本低,无异响,同时具有安全保障。
