The invention is suitable for the technical field of auxiliary driving, and particularly relates to a vehicle overtaking driving method and system in a self-adaptive cruise mode. The method comprises the steps that a sensing unit recognizes that a self-vehicle is a vehicle ID0, a vehicle in front of the self-vehicle is a vehicle ID1, a vehicle in front of the left of the self-vehicle is a vehicle ID2, a vehicle in front of the right of the self-vehicle is a vehicle ID3, a vehicle in rear of the left of the self-vehicle is a vehicle ID4, and a vehicle in rear of the right of the self-vehicle is a vehicle ID5; vehicle speed information Vi and longitudinal distance information Li are obtained, overtaking acceleration is calculated based on the positions of all the vehicles and the vehicle speed information Vi and the longitudinal distance information Li of all the vehicles, and the vehicles are controlled to complete overtaking through a control execution unit. According to the method, the vehicle speed and the relative distance of the vehicles around the vehicle are obtained, the condition that the overtaking condition is met and the acceleration required during overtaking are judged, and when the side-by-side driving possibility exists, the vehicles are correspondingly judged and calculated, so that the side-by-side driving time of the vehicles is shortened to the minimum under the high-speed driving condition, and the safety and the driving comfort of the vehicles are improved.
本发明适用于辅助驾驶技术领域,尤其涉及一种自适应巡航模式下车辆超车行驶方法及系统,所述方法包括:通过感知单元识别自车为车辆ID0、自车前方车辆为车辆ID1、自车左前方车辆为车辆ID2、自车右前方车辆为车辆ID3、自车左后方车辆为车辆ID4和自车右后方车辆为车辆ID5;获取车速信息Vi以及纵向距离信息Li,基于各个车辆位置以及各个车辆的车速信息Vi和纵向距离信息Li计算超车加速度,通过控制执行单元控制车辆完成超车。本发明获取自车周围车辆的车速和相对距离,判断满足超车条件和超车时所需的加速度,当存在并排行驶可能性时,对车辆进行相应判断和计算,使高速行驶情况下,车辆并排行驶的时间降低到最低,提升车辆的安全性和驾驶的舒适性。
