The invention provides a crawling safety control method of a new energy vehicle and the vehicle, belongs to the field of new energy vehicle control, and particularly relates to a crawling control method of an electric vehicle. When the whole vehicle is in the crawling mode, the controller recognizes the off-seat signal and the door opening signal, and if the door opening signal or the off-seat signal is effective, the controller controls the vehicle to exit the crawling mode; when the controller recognizes that the door opening signal is invalid and the seat leaving signal is invalid again, the opening degree of an accelerator pedal or a brake pedal is detected; and if it is detected that the opening degree of any one of the accelerator pedal and the brake pedal is larger than a set value, after the opening degrees of the accelerator pedal and the brake pedal are both smaller than a set opening degree, the vehicle is controlled to enter a crawling mode. The safety risk caused by vehicle crawling driving when a driver is in an off-seat state or a vehicle door opening state is avoided; the opening degree of the pedal is detected to be larger than the set value and then smaller than the set opening degree, so that potential safety hazards caused by vehicle crawling driving before a driver is ready are avoided.
本发明提供了一种新能源车辆的蠕行安全控制方法及车辆,属于新能源整车控制领域,尤其涉及一种电动车辆的蠕行控制方法。整车处于蠕行模式时,控制器识别离座信号和开门信号,若开门信号或离座信号有效,则控制器控制车辆退出蠕行模式;当控制器再次识别到开门信号无效且离座信号无效时,检测油门踏板或制动踏板开度;若检测到油门踏板或制动踏板中任一踏板的开度大于设定值,则等待油门踏板和制动踏板的开度均小于一个设定开度后,控制车辆进入蠕行模式。本发明避免了驾驶员处于离座状态或车门打开状态下时,车辆蠕行行驶导致的安全风险;检测踏板的开度大于设定值且之后又小于设定开度是为了避免驾驶员未做好准备车辆就蠕行行驶导致安全隐患。
