The invention discloses a method and system for improving the safety level of an automatic slope parking function of a whole vehicle and an automobile, and belongs to the technical field of new energy automobiles. According to the method, redundant backup of parking slope sliding is achieved, different measures are adopted according to the slope sliding degree of the vehicle, the slope sliding degree is judged to be primary, first redundancy is adopted, and the wheel end pressure is increased to improve braking force; when the slope sliding degree is judged to be high, second redundancy is adopted, parking braking is requested, meanwhile, when the slope sliding degree is in the primary stage, after the wheel end pressure is increased to improve the braking force, slope sliding still exists, second redundancy parking braking is adopted, and under the condition that the wheel end pressure and parking braking are increased in a linkage mode, the function safety level of the vehicle is improved; the problem that in the prior art, only ESC independent control is adopted, and consequently the safety level of the automatic hill-holding function is insufficient is solved.

    本发明公开了一种提升整车自动驻坡功能安全等级的方法、系统及汽车,属于新能源汽车技术领域,本申请有驻车溜坡的冗余备份,根据车辆溜坡程度,分别采取不同措施,溜坡程度判断为初级,采用第一冗余,增加轮端压力提高制动力,溜坡程度判断为高级,则采用第二冗余,请求驻车制动,同时,在溜坡程度为初级阶段,增加轮端压力提高制动力后,仍有溜坡,则采用第二冗余驻车制动,在联动增加轮端压力和驻车制动的情况下,提升了车辆功能安全等级,解决了现有技术中只采用ESC单独控制,而导致自动驻坡功能安全等级不足问题。
