The invention discloses a vehicle self-adaptive cruise control method suitable for complex working conditions. Comprising the following steps: calculating a constant-speed cruise minimum safe distance according to vehicle acquisition data, judging whether a vehicle meets a constant-speed cruise condition or not, and if so, executing constant-speed cruise; calculating the minimum safe distance of vehicle following driving, judging whether the vehicle meets the vehicle following driving condition or not, if so, executing vehicle following driving, calculating the expected vehicle following distance based on a variable safe headway model (VSTH), and deciding whether to change the lane or not according to the speed dissatisfaction degree of a driver and the environmental condition; and whether the vehicle is in the sudden working condition or not is judged, if yes, the vehicle executes a dual-mode collision avoidance control strategy, and if collision cannot be avoided, the vehicle adopts the maximum braking force for emergency braking. The method has the advantages that the variable safe time headway model (VSTH) is built, the safe and reliable expected vehicle following distance is provided during vehicle following driving, the dual-mode collision avoidance control strategy is built, and vehicle collision accidents are avoided to the maximum extent.

    本发明公开了一种适用于复杂工况的车辆自适应巡航控制方法。包括如下步骤:根据车辆采集数据,计算定速巡航最小安全距离,判断车辆是否满足定速巡航条件,若是则执行定速巡航;计算跟车行驶最小安全距离,判断车辆是否满足跟车行驶条件,若是则执行跟车行驶,基于可变安全车头时距模型(VSTH)计算期望跟车距离,并依据驾驶员速度不满意度和环境条件决策是否换道行驶;判断车辆是否处于突发工况,若是,则车辆执行双模式避撞控制策略,若无法避免碰撞,则车辆采用最大制动力进行紧急制动。本申请的有益效果如下:搭建可变安全车头时距模型(VSTH),在跟车行驶时提供安全可靠的期望跟车距离,搭建双模式避撞控制策略,最大化避免车辆碰撞事故发生。
