摘要： A variable transmission ratio steering apparatus for a vehicle is configured with an input shaft coupled to a steering wheel of the vehicle, a sensor for sensing a rotation angle of the input shaft, an output shaft operatively linked to steerable road wheels of the vehicle, an actuator having an electric motor which is configured to vary a transmission ratio between a rotation angle of the output shaft and the rotation angle of the input shaft, and a controller. More specifically, the controller includes a desired rotation angle calculation unit, a difference calculation unit, and a difference limitation unit, whereby a rotation angle of a rotor of the electric motor is limited. With such a configuration, a rotation speed of the rotor of the electric motor can be limited by limiting the rotation angle of the rotor, and consequently, audible operation noises arising from the electric motor can be minimized.

摘要： A vehicle steering control system is provided which is capable of reliably protecting a motor for driving a wheel steering shaft. The offset output characteristic of a current sensor for detecting the electric current applied to the steering shaft drive motor is actually measured prior to the actual use of the steering control system, and offset compensation information is prepared based on the measured value of the offset output characteristic for storage in an EEPROM. Further, an output value of the current sensor and an output value of a reference current measuring system are measured independently of each other with the supply voltage for use in measurement being set to a constant value. Then, current gain compensation information is prepared based on the output values so measured and is stored in the EEPROM. In the later actual use (i.e., after shipment) of the control system, the output of the current sensor is compensated based on the offset compensation information and the current gain compensation information.
摘要翻译：提供一种能够可靠地保护用于驱动车轮转向轴的电动机的车辆转向控制系统。在实际使用转向控制系统之前，实际测量了用于检测施加到转向轴驱动电动机的电流的电流传感器的偏移输出特性，并且基于偏移输出特性的测量值来准备偏移补偿信息用于存储在EEPROM中。此外，电流传感器的输出值和参考电流测量系统的输出值彼此独立地测量，而用于测量的电源电压被设置为恒定值。然后，根据所测量的输出值准备当前的增益补偿信息，并存储在EEPROM中。在控制系统的后续实际使用（即出货后）中，基于偏移补偿信息和当前增益补偿信息来补偿电流传感器的输出。
