摘要： A hand wheel actuator for a steer-by-wire steering system having a steering feel that meets drivers' expectations is provided with a housing having an aperture, a steering shaft extending through the aperture and rotatably supported by the housing, an electric motor, a position sensor and torque sensor, and a mechanical steering feel enhancement device. The mechanical steering feel enhancement device is attached to the housing and provides a positive stop function, a return-to-center function, and/or a friction/weight function. The mechanical steering feel enhancement device is in mechanical communication with the steering shaft and may exist as a separate unitary subassembly prior to being installed on the housing. The electric motor has an output shaft that is in mechanical communication with the steering shaft for imparting a torque to the steering shaft.

摘要： 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.
摘要翻译：一种用于船舶的船舶转向控制系统，包括：方向控制系统，包括舵位置传感器; 一个舵控制系统，包括以下中的至少一个：用于产生和传送舵位置信号的舵位置传感器和可选的扭矩传感器以产生和传送舵扭矩传感器信号。该系统可选地包括船体速度传感器和与船只速度传感器，舵控系统和方向控制系统可操作地通信的主控制单元。主控制单元包括响应于船体速度信号，舵扭矩传感器信号和舵位置信号产生方向指令信号的位置控制处理。主控制单元包括基于舵扭矩传感器信号，舵位置信号和船体速度信号产生舵指令信号的转矩控制处理。
