The invention relates to the field of new energy automobile parking control, in particular to an automatic parking method based on a pure electric vehicle. The method comprises the steps of judging whether a current gear signal is a P gear or not; a, when a current gear signal is a P gear, starting a parking mode, judging whether the current running speed is larger than the set vehicle speed or not, and if the current running speed is smaller than or equal to the set vehicle speed, pulling up an EPB switch automatically, and an executing mechanism of a parking braking system starting to work; if the front running speed is greater than the set vehicle speed, not pulling up the EPB switch, and the executing mechanism of the parking braking system doing no work; and b, when the current gear signal is not the P gear, not entering the parking mode . The automatic parking control method has the beneficial effects that the problems of low driving safety, poor comfort and low intelligence of the pure electric vehicle are solved, and the driving safety, comfort and intelligence of the pure electric vehicle can be effectively improved by designing the automatic parking control process and method among the VCU, the EPB, the ESC and the GSM.

    本发明涉及新能源汽车驻车控制领域,具体是一种基于纯电动汽车自动驻车方法。包括以下步骤:判断当前挡位信号是否为P挡;a、当前挡位信号是P挡时,进入驻车模式,判断当前行车速度是否大于设定车速,如果当前行车速度小于等于设定车速时,EPB开关自动拉起,驻车制动系统执行机构开始工作;如果前行车速度大于设定车速时,EPB开关不拉起,驻车制动系统执行机构不工作;b、当前挡位信号非P挡时,不进入驻车模式。本发明所带来的有益效果在于:解决了纯电动汽车驾驶安全性低,舒适性差和智能化低的问题,通过在VCU、EPB、ESC和GSM之间设计自动驻车的控制流程及方法,可有效提高纯电动汽车驾驶的安全性、舒适性和智能化。
