    • A system for indicating an impending vehicle maneuver within a predetermined distance is provided. The system includes a navigational system and a control module. The navigational system receives a vehicle destination and determines a current geographical vehicle position. The navigational system determines if the impending vehicle maneuver is required within the predetermined distance based on the vehicle destination and the current geographical vehicle position. The control module is in communication with the navigational system and a handwheel. The control module sends a signal that creates a steering assist torque in the handwheel if the impending vehicle maneuver is required.
    • 提供了一种用于在预定距离内指示即将发生的车辆操纵的系统。 该系统包括导航系统和控制模块。 导航系统接收车辆目的地并确定当前的地理位置。 导航系统基于车辆目的地和当前的地理车辆位置确定在预定距离内是否需要即将发生的车辆机动。 控制模块与导航系统和手轮通信。 如果需要即将进行的车辆操纵,则控制模块发送在手轮中产生转向辅助转矩的信号。

    • A watercraft steer-by-wire control system for watercraft comprising: a direction control system including a rudder position sensor; a helm control system including at least one of; a helm position sensor to produce and transmit a helm position signal and an optional torque sensor to produce and transmit a helm torque sensor signal. The system optionally including a watercraft speed sensor and a master control unit in operable communication with the watercraft speed sensor, the helm control system, and the direction control system. The master control unit includes a position control process for generating the directional command signal in response to the watercraft speed signal, the helm torque sensor signal and the helm position signal. The master control unit includes a torque control process for generating the helm command signal, based on the helm torque sensor signal, the helm position signal and the watercraft speed signal.

    • A control system to determine a hands on wheel (HOW) condition is provided. The control system includes a sensor that monitors an amount of applied torque exerted upon a hand wheel, and a control module for monitoring the sensor. The control module includes a notch filter to attenuate a normal column mode frequency from the amount of applied torque to produce a filtered torque signal. The normal column mode frequency represents a range of vibrational modes of the hand wheel based on a hands off wheel condition. The control module includes a state detector to receive the filtered torque signal from the notch filter. The state detector determines if the HOW condition exists based on if the filtered torque signal exceeds an ON threshold torque value.
    • 提供了一种用于确定手轮(HOW)状况的控制系统。 控制系统包括监测施加在手轮上的施加扭矩量的传感器,以及用于监控传感器的控制模块。 控制模块包括陷波滤波器,用于从施加的转矩量衰减正常列模式频率,以产生滤波的转矩信号。 正常列模式频率表示基于手轮状态的手轮的振动模式的范围。 控制模块包括状态检测器,用于从陷波滤波器接收滤波的扭矩信号。 状态检测器基于滤波的扭矩信号是否超过ON阈值转矩值来确定是否存在HOW条件。
