    • A vehicle steering control system for a vehicle/trailer combination that provides rear-wheel steering assist to improve the vehicle/trailer combination stability and handling performance. The control system provides an open-loop feed-forward control signal based on hand-wheel angle and vehicle speed. The control system includes a vehicle yaw rate command interpreter that provides a vehicle closed-loop feedback control signal based on the yaw rate of the vehicle, a trailer yaw rate command interpreter that provides a trailer closed-loop feedback control signal based on the yaw rate of the trailer, and a vehicle lateral acceleration command interpreter that provides a closed-loop feedback control signal based on the lateral acceleration of the vehicle. The closed-loop feedback signals are added together and then combined with the open-loop feed-forward control signal to provide the rear-wheel steering assist.
    • 一种用于车辆/拖车组合的车辆转向控制系统,其提供后轮转向辅助以改善车辆/拖车组合的稳定性和操纵性能。 控制系统基于手轮角度和车速提供开环前馈控制信号。 控制系统包括车辆横摆速度命令解释器,其基于车辆的横摆角速度提供车辆闭环反馈控制信号;拖车横摆速度命令解释器,其基于横摆率提供拖车闭环反馈控制信号 以及车辆横向加速度指令解释器,其基于车辆的横向加速度提供闭环反馈控制信号。 将闭环反馈信号加在一起,然后与开环前馈控制信号相结合,以提供后轮转向辅助。

    • A method to assist steering of a vehicle equipped with an active steering system when operating in a reverse direction is provided. The method comprises monitoring vehicle operating characteristics and an operator steering input. Boundaries of a target region and a reference point are determined. A target steering angle range is calculated based upon the reference point and the target location. A controlled steering angle of the active steering system is corrected when the operator steering input is outside the target steering angle range. An aspect of the invention included determining the reference point comprising a point of intersection of a first vector and a second vector, the first vector parallel to and passing through a centerline of a rear axle of the vehicle and the second vector perpendicular to and passing through a centerline of an inside front steerable wheel of the vehicle.
    • 提供了一种在反向工作时辅助配备有主动转向系统的车辆的转向的方法。 该方法包括监视车辆操作特性和操作者转向输入。 确定目标区域和参考点的边界。 基于参考点和目标位置计算目标转向角范围。 当操作者转向输入超出目标转向角范围时,主动转向系统的受控转向角被校正。 本发明的一个方面包括确定包括第一矢量和第二矢量的交点的参考点,平行于并经过车辆后轴的中心线的第一矢量和垂直于并经过的第二矢量 车辆内侧可转向车轮的中心线。

    • A vehicle-trailer back-up control system that employs an active front steer sub-system. The system includes a smart hitch controller that receives a vehicle speed signal and a hand-wheel angle signal, and calculates a hitch angle command signal. The system further includes a hitch angle sensor that measures the hitch angle between the vehicle and the trailer that is compared to the hitch angle command signal to generate a hitch angle error signal. A PID control unit receives the hitch angle error signal, and generates a corrected road wheel angle signal based on proportional and derivative gains. The corrected road wheel angle signal is used to generate a motor angle signal that is applied to a steering actuator to be combined with the steering angle signal to generate the front wheel steering signal during a back-up maneuver.
    • 一种采用主动前转向子系统的车辆拖车后备控制系统。 该系统包括接收车速信号和手轮角度信号的智能牵引控制器,并计算牵引角度指令信号。 该系统还包括一个牵引角度传感器,其测量与牵引角度指令信号相比的车辆和拖车之间的牵引角度,以产生牵引角误差信号。 PID控制单元接收牵引角误差信号,并根据比例和微分增益产生校正的车轮角度信号。 校正后的车轮角度信号用于产生电动机角度信号,该电动机角度信号被施加到与转向角信号组合的转向致动器,以在后备操纵期间产生前轮转向信号。
