The invention discloses a self-adaptive cruise curve control method for a distributed drive electric motor coach. The control method comprises the following specific steps of locking a following target vehicle, sensing the moving posture of the target, detecting a curve area, estimating the curvature of a curve, estimating the yaw velocity, judging the control right of the vehicle, and controllingthe self-adaptive cruise of the curve of the vehicle. The method has obvious advancement and innovation in the aspects of target recognition accuracy and curve driving safety, a new control method isprovided for loss and locking of the cruise target and vehicle body sideslip control in the curve process, the defects of a previous self-adaptive cruise system are effectively overcome, and the driving safety is improved.
本发明公开的是一种分布式驱动电动客车自适应巡航弯道控制方法,该控制方法包括以下具体步骤:锁定跟随目标车辆->目标运动姿态感知->弯道区检测->弯道曲率的估算->横摆角速度的估算->判断车辆控制权->控制车辆弯道的自适应巡航。本发明对于目标识别的准确率以及弯道行驶安全性方面,有明显的先进性和创新性,对于弯道过程中,巡航目标的丢失和锁定,以及车身侧滑控制提出了新的控制方法,有效解决了以往自适应巡航系统存在的不足和缺陷,提高了驾驶安全性。
