The invention discloses a pure electric vehicle AUTO HOLD technology implementation mode, which is characterized in that a pressure regulating valve, an ASR valve and a two-way single-channel valve are added on the basis of an original service brake circuit of a pure electric vehicle, and a brake pedal, a rear air cylinder, a relay valve and a rear brake air chamber in the original service brake circuit are combined, so that the functions of automatic hill parking and hill starting for preventing slip breakage are realized; the AUTO HOLD function is called for short. According to the invention, the driving safety guarantee functions such as automatic slope parking and slip breaking prevention are realized, the problem of unnecessary accidents caused by slip breaking when a driver starts on a slope is solved, the problem that the driver must pull a brake or step on a brake pedal when waiting for traffic lights is also solved, and the driving experience of the driver is improved; the system can be effectively applied to various pure electric vehicles, is convenient to popularize traditionally, and is low in cost, high in safety, good in using effect and convenient to popularize and use.

    本发明公开了一种纯电动汽车AUTO HOLD技术实现方式,在纯电动汽车原有的行车制动回路种增加一个调压阀、一个ASR阀、一个双向单通道阀,结合原行车制动回路中的制动踏板、后储气筒、继动阀、后制动气室,从而实现自动驻坡、坡道起步防溜破功能,简称“AUTO HOLD”功能。本发明实现自动驻坡、防溜破等驾驶安全保障功能,解决了驾驶员在坡道上起步溜破造成不必要的事故的问题,同时也解决驾驶员在等红绿灯必须拉手刹或者踩制动踏板的问题,提升了驾驶员驾车体验;本发明能够有效应用在各种纯电动汽车上,也方便在传统上推广,成本低廉,安全性高,使用效果好,便于推广使用。
