The invention discloses a crawling vehicle speed control method and system for a hydrogen energy vehicle. When the whole vehicle enters a driving state, whether a whole vehicle enters a gear crawlingmode or not is judged through a whole vehicle controller-VCU; if the vehicle can enter the gear crawling mode, whether the crawling vehicle speed of the current whole vehicle is valid or not is judgedthrough the VCU; if so, a gear crawling state set by the user is entered; if not, a default crawling state of the gear system is entered; in different crawling modes, based on the crawling vehicle speed effectiveness of the whole vehicle, the vehicle speed is controlled to be continuously kept at the crawling target vehicle speed, whether the crawling mode of the corresponding gear is entered ornot is judged by measuring the distance between the whole vehicle and the front vehicle or the obstacle, the crawling vehicle speed needed by a user is dynamically calculated and controlled in real time, and the driving smoothness and the subjective feeling of a driver and passengers are both considered while the function is improved.

    本发明公开了一种用于氢能汽车的蠕行车速控制方法及系统,在整车进入行驶状态时,通过整车控制器‑VCU来判断整车是否进入档位蠕行模式,若可以进入整车进入档位蠕行模式,则通过VCU判断当前整车的蠕行车速是否有效,若有效则进入用户设置档位蠕行状态,若无效则进入档位系统默认蠕行状态,在不同的蠕行模式下,基于整车的蠕行车速有效性,控制车速持续保持在蠕行目标车速,且通过测定整车与前车或障碍物之间的距离,判断是否进入到对应档位的蠕行模式,本发明对用户所需的蠕行车速实时动态的计算和控制,在提高功能的同时,兼顾驾驶平顺性和驾乘者的主观感受。
