    摘要: A steer-by-wire system includes a steering wheel; a steering wheel sensor coupled to the steering wheel for sensing the position of the steering wheel and producing a signal indicative of the position of the steering wheel; a controller in signal communication with the steering wheel sensor for receiving the signal indicative of the position of the steering wheel from the steering wheel sensor and producing a signal indicative of a desired steering wheel feedback torque; and a tactile feedback device in signal communication with the controller for receiving the signal indicative of the desired steering wheel feedback torque and providing a corresponding torque to the steering wheel.

    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: A steering system providing an assist torque to a handwheel is provided, and includes a proportional gain module and a torque command module. The proportional gain module determines a proportional gain value. The proportional gain value is scheduled as a function of a lateral position error and at least one of the following: a near field heading angle, a far field heading angle, a curvature of the lane, and a lateral position of the vehicle. The torque command module determines the torque assist based on the proportional gain value.
