The invention provides a self-adaptive cruise control method which comprises the steps that the speed of a vehicle, the speed of a front vehicle, the relative speed of the vehicle and the front vehicle and the relative distance between the vehicle and the front vehicle are obtained in real time, and the front vehicle is the vehicle in front in the driving direction within the preset range of the vehicle; according to the relation between the speed of the vehicle and the speed of the front vehicle and the relative speed of the two vehicles, the cruise switching distance of the vehicle is determined; and switching the cruise control mode of the vehicle according to the size relationship between the relative distance of the two vehicles and the cruise switching distance of the vehicle. According to the method, different cruise switching distances are determined according to different working conditions while the safety is guaranteed, so that the cruise switching distances can be better matched with actual driving working conditions, and the driving comfort is improved.
本发明提供了一种自适应巡航控制方法,该方法包括:实时获取本车辆的速度、前方车辆的速度,以及本车辆和前方车辆的两车相对速度和两车相对距离,前方车辆为在本车辆预设范围内的行驶方向上的前方的车辆;根据本车辆的速度与前方车辆的速度大小关系和两车相对速度,确定本车辆的巡航切换距离;根据两车相对距离与本车辆的巡航切换距离的大小关系,切换本车辆的巡航控制模式。本发明保证安全性的同时,针对不同工况,确定不同的巡航切换距离,以更好的与实际行驶工况相匹配,提高行驶舒适性。
