The invention discloses an overtaking control method and system, and belongs to the technical field of vehicle auxiliary driving, and the method comprises the steps: judging whether an overtaking auxiliary function is activated or not based on a current vehicle speed, environment data of a vehicle and a turn light dial-up state, judging an overtaking demand through a controller, sending a control instruction to an electronic stability control system (ESC), and adjusting a TTC value with a front vehicle; the controller sends transverse and longitudinal acceleration instructions to control an electronic power steering (EPS) system to assist a driver to complete lane changing, and meanwhile an electronic stability control (ESC) system accelerates to complete overtaking. By integrating identification signals of the foresight camera and the millimeter wave angle radar, objects in blind areas in front of the left and right of the vehicle and on the side of the vehicle can be judged, the overtaking intention of a driver can be autonomously identified, the vehicle following speed and distance can be autonomously accelerated and controlled, the driver is assisted in steering, and comfortable overtaking under the self-adaptive cruise working condition is achieved.
本发明公开了一种超车控制方法及系统,属于车辆辅助驾驶技术领域,基于当前车速,自车处的环境数据以及转向灯拨起状态,判断超车辅助功能是否被激活,通过控制器判断超车需求,发送控制指令至电子稳定控制系统ESC,调整与前车的TTC值;控制器发送横纵向加速度指令,控制电子助力转向系统EPS协助驾驶员完成换道,同时电子稳定控制系统ESC加速完成超车。本发明通过整合前视摄像头和毫米波角雷达的识别信号,能够判断车辆左右车前和车侧盲区内的物体,能够自主识别驾驶员超车意图,自主加速控制跟车车速和距离,并协助驾驶员转向,实现自适应巡航工况下的舒适超车。
