The invention discloses a crawling vehicle speed control method and system. The crawling vehicle speed control method comprises the steps that: the working condition information of a vehicle is obtained when the vehicle enters a crawling state, wherein the working condition information comprises a driving speed and a brake pedal opening degree B; and whether to execute a crawling mode or not is selected according to the working condition information of the vehicle, wherein the creeping mode comprises a constant-speed creeping mode and a variable-speed creeping mode, wherein the constant-speedcreeping mode provides a high creeping target vehicle speed, and the variable-speed creeping mode provides a low creeping target vehicle speed, and the constant-speed creeping mode and the variable-speed creeping mode are specially used for solving the problem that a congested road section or a vehicle travels in a parking lot. On the basis of the condition of a road, generally, the crawling target vehicle speed of the constant-speed crawling mode is high, so that the requirement of a driver for low-speed driving at ordinary times can be met, and when the driver enters the congested road section and the parking lot, the target vehicle speed required by the driver is low, so that the variable-speed crawling mode is set to provide a low variable crawling target vehicle speed, and therefore,such problems can be solved.
本发明公开了一种蠕行车速的控制方法和系统,其中蠕行车速的控制方法为:当车辆进入蠕行状态时,获取车辆的工况信息;其中,工况信息包括:行驶车速和刹车踏板开度B;根据车辆的工况信息选择是否执行蠕行模式;其中,蠕行模式包括定速蠕行模式和变速蠕行模式。定速蠕行模式提供一种较高的蠕行目标车速,变速蠕行模式提供一种较低的蠕行目标车速,专为解决拥堵路段或者行驶在停车场内的情况。在道路允许的情况下,通常定速蠕行模式的蠕行目标车速较高,可以满足驾驶员平时低速驾驶的需求,而进入拥堵路段和停车场内时,通常驾驶员需求的目标车速较低,因此设定变速蠕行模式提供较低的可变蠕行目标车速可以解决该类问题。
