    • A power steering system makes use of an electric motor to produce an auxiliary torque added to the torque which is applied to the steering wheel of a vehicle by the driver. The system includes a motor driver for driving the motor and a motor braking circuit for braking the motor. When the torque manually applied to the steering shaft of the vehicle is greater than a predetermined reference torque, an electronic control apparatus causes the motor driver to energize the motor according to the difference between these two torques. When the former torque is less than the reference torque, the control apparatus causes the motor braking circuit to brake the motor. In this way, the torque that the driver of the vehicle must apply to steer the vehicle is maintained equal to the reference torque, irrespective of the vehicle velocity. The reference torque is set by means of a variable-resistor.
    • 动力转向系统利用电动机产生加到驾​​驶员对车辆方向盘施加的转矩的辅助转矩。 该系统包括用于驱动马达的马达驱动器和用于制动马达的马达制动电路。 当手动施加到车辆的转向轴的扭矩大于预定的参考扭矩时,电子控制装置使得电动机驱动器根据这两个转矩之间的差来激励电动机。 当前一转矩小于参考转矩时,控制装置使马达制动电路制动电动机。 以这种方式,车辆驾驶员必须施加的转向车辆的扭矩保持等于参考扭矩,而与车速无关。 参考转矩通过可变电阻器来设定。
