The invention discloses an intelligent overtaking avoidance method for a driving assistance system, and the method comprises the steps: obtaining the information of a first lane where a vehicle is located, and judging whether a vehicle in front of the vehicle hinders the overtaking or not; acquiring information of an overtaken vehicle and information of a second lane where the overtaken vehicle is located; judging the collision time TTC of the vehicle and the overtaken vehicle; after the overtaken vehicle disappears from the detection range of the radar in front of the vehicle, the overtaken vehicle continues to run for a period of time, and then the distance D1 between the overtaken vehicle and the vehicle is judged; when the distance D1 between the overtaken vehicle and the vehicle is larger than a preset value Dy, it is judged that the overtaking action is completed, and the vehicle is controlled to deviate towards the center of the first lane in the first lane and return to the normal driving state. According to the intelligent overtaking avoidance method of the driving assistance system, the vehicle can avoid surrounding vehicles as much as possible in the overtaking process, and the safety and reliability of the overtaking process are ensured.
本发明公开了一种驾驶辅助系统的智能超车避让方法,获取本车所在的第一车道的信息,判断本车前方是否有车辆阻碍超车;获取被超车辆的信息及被超车辆所在的第二车道的信息;判断本车与被超车辆的碰撞时间TTC;当被超车辆从本车的车前雷达探测范围内消失后,继续行驶一段时间后判断被超车辆与本车之间的间距D1;当被超车辆与本车之间的间距D1大于预定值Dy时,判定完成超车动作,控制本车在第一车道内向第一车道的中心偏移,并回归正常行驶状态。本发明的驾驶辅助系统的智能超车避让方法,能够使得车辆在超车过程中尽量避开周围车辆、确保超车过程的安全可靠性。
