摘要： A voltage regulating control system for vehicle systems which includes a power supply providing electrical power to the system and having a predefined maximum voltage. A controller controls an actuator performing a vehicle system function and the electrical load in the system wherein the controller has a first predefined minimum operating voltage. A voltage regulator communicates with the controller and the power supply and senses a system input voltage in the system. In response to a sensed voltage dip in excess of a predetermined value, the regulator changes an effective electrical impedance of the system to maintain the system voltage at a predefined minimum voltage greater than the first predefined minimum operating voltage required by the controller.

摘要： A steering system for a vehicle includes a steering handle having a center position, a steer-by-wire system, and a steer feel control system. The steer-by-wire system senses the position of the steering handle and controls the steering angle of a steerable vehicle wheel as a function of the position of the steering handle. The steer feel control system includes a motor that is operatively associated with the steering handle, and has first and second modes of operation. In the first mode, the steer feel control system applies a force to the steering handle as a function of vehicle's operating condition, and in the second mode, the motor may be shorted. The steer feel control system may also include a spring that biases the steering handle towards to the center position. A method is used to provide steering feel to a steering handle of a vehicle having a steer-by-wire system and a steer feel control system, when the steer feel control system fails. The method may include shorting a motor of the steer feel control system to provide steer feel to the steering handle. The method may also include biasing the steering handle towards its center position using a spring.
摘要翻译：用于车辆的转向系统包括具有中心位置的转向手柄，线控转向系统和转向控制系统。线控转向系统感测转向手柄的位置，并根据转向手柄的位置来控制可转向车轮的转向角。转向控制系统包括与转向手柄可操作地相关联的电动机，并且具有第一和第二操作模式。在第一模式中，转向控制系统根据车辆的运行状况向转向手柄施加力，而在第二模式中，电动机可能短路。转向控制系统还可以包括将转向手柄偏向中心位置的弹簧。当转向控制系统失效时，使用一种方法来提供具有线控转向系统和转向控制系统的车辆的转向手柄的转向感觉。该方法可以包括使转向控制系统的电机短路以向转向手柄提供转向感。该方法还可以包括使用弹簧将转向手柄偏向其中心位置。
