The invention belongs to the technical field of intelligent vehicle control, and provides a vehicle speed control method and system under a cruise working condition, and when an adjacent vehicle and a self vehicle run side by side and the self vehicle is switched from first constant speed cruise to accelerated running, second constant speed cruise is carried out at a vehicle speed increased when accelerator acceleration is finished; when the adjacent vehicle and the vehicle run in a staggered manner, the first constant-speed cruise is switched again, so that the intention of the driver can be effectively judged; when it is judged that the adjacent vehicle has the lane changing intention through the signal lamp of the adjacent vehicle, the driving angle of the adjacent vehicle is judged; when the lane changing signal lamp of the adjacent vehicle is turned on and the front wheels tend to the lane where the vehicle is located, the vehicle is controlled to run at a first speed in a decelerated mode; and when the lane changing signal lamp of the adjacent vehicle is turned on and the front wheels tend to any one of the lanes where the vehicle is located, the vehicle is controlled to run at the second speed at the second speed, the intention of a driver on the adjacent lane is judged, the speed is actively reduced, the overtaking space is made for the adjacent vehicle, and the safety is improved.
本发明属于智能车控制技术领域,提供了一种巡航工况下的车速控制方法及系统,当邻车与自车并排行驶,且自车由第一定速巡航切换到加速行驶时,以油门加速结束时提升的车速进行第二定速巡航;直到邻车与自车错开行驶,重新切换到第一定速巡航,可有效判断驾驶员意图;以及当通过邻车的信号灯判断邻车有变道意图时,判断邻车行驶角度;当同时满足邻车变道信号灯亮起和前轮倾向于自车所在车道时,控制自车以第一速率进行降速行驶;当满足邻车变道信号灯亮起和前轮倾向于自车所在车道中的任意一个时,控制自车以第二速率进行降速行驶,判断相邻车道驾驶员意图,主动降速,给邻车让出超车空间,提高了安全性。
