The invention discloses a self-adaptive cruise low-speed vehicle following control method and device and a vehicle. The method comprises the following steps: in an adaptive cruise mode, if it is identified that a current vehicle is in a non-pure electric drive mode and a current road slope value is less than or equal to a first slope threshold, taking a larger value of a starting cruise torque anda creeping torque as a cruise demand torque. According to the invention, the self-adaptive cruise working condition is selected based on a driver; by combining different driving modes and gradient road conditions, a low-speed vehicle following control strategy is optimized, the working condition of starting vehicle following at the gradient of 0-15% can be achieved, the comfort of the low-speed vehicle following starting working condition is optimized, the comfort of self-adaptive cruise low-speed driving is improved, and the NVH of low-speed vehicle following starting under the whole-road working condition is good.
本发明公开了一种自适应巡航低速跟车控制方法、装置及车辆。该方法包括在自适应巡航模式下,若识别到当前车辆处于非纯电驱动的驱动模式,且当前道路坡度值小于等于第一坡度阈值时,将起步巡航扭矩和蠕行扭矩中的较大值作为巡航需求扭矩。本发明能够基于驾驶员选择自适应巡航工况下,结合不同的驱动模式和坡度路况,优化了低速跟车控制策略,能够实现在0‑15%坡度起步跟车的工况,优化低速跟车起步工况舒适性,提高自适应巡航低速驾驶的舒适性,且全路工况低速跟车起步NVH较好。
