摘要： A vehicle steering apparatus having a variable gear ratio unit arranged midway along a steering transmission system for connecting a steering wheel and a tire to change a transmission ratio upon driving a motor includes a connecting unit for stopping actuation of the variable gear ratio unit in accordance with an external signal to connect the input side of the variable gear ratio unit which is connected to the steering wheel to the output side of the variable gear ratio unit which is connected to the tire. Even if a reverse input acts from a tire side during traveling, the relationship between the steering amount of the steering wheel and the turning amount of the tire can be kept unchanged.

摘要： An electric steering control device is provided which is capable of enabling the driver to perform steering manipulation stably without being substantially affected by the ambient temperature and the heat generation of the control device. The control device comprises a temperature sensor for detecting the temperature of a circuit board mounting a motor drive circuit thereon and a compensation section for compensating an electric current command value based on the board temperature detected by the temperature sensor, so that en electric motor for exerting an assist force on a vehicle steering mechanism is driven by the compensated electric current command value output from a motor drive circuit. Therefore, the steering operation can be done stably without being substantially affected by the ambient temperature and the heat generation of the control device. In particular, since the temperature sensor is arranged not on the motor drive circuit per se but on a circuit board mounting the motor drive circuit thereon, the freedom can be heightened in arranging the temperature sensor. Further, since the temperature sensor for heat control of a spiral cable provided on the electric motor is utilized also for compensation of the electric current command value, the components for the control device can be reduced in number.
摘要翻译：提供一种电动转向控制装置，其能够使驾驶员能够稳定地执行转向操作，而不受基本上受到环境温度和控制装置的发热的影响。控制装置包括温度传感器，用于检测在其上安装电动机驱动电路的电路板的温度，以及补偿部分，用于基于由温度传感器检测到的电路板温度补偿电流指令值，使得用于施加电动机由电机驱动电路输出的补偿电流指令值驱动车辆转向机构上的辅助力。因此，可以在不受环境温度和控制装置的发热的显着影响的情况下稳定地进行转向操作。特别地，由于温度传感器本身不设置在电动机驱动电路上，而是在其上安装电动机驱动电路的电路板上，因此可以在布置温度传感器时提高自由度。此外，由于设置在电动机上的螺旋形电缆的热控温度传感器也用于电流指令值的补偿，所以可以减少控制装置的部件数量。

摘要： A vehicular steering control apparatus controls the wheel steering amount of wheels based on a steering angle and an assist angle obtained by multiplying a steering speed by a gain. If the amount of power control differs between the left wheel and the right wheel, the value of gain is increased. The amount of power control includes, for example, the amount of braking control and the amount of drive control. If the assist angle is increased by increasing the gain, the magnitude of the wheel steering amount relative to the steering angle increases, so that a driver can correct the orientation of the vehicle body by performing a small amount of steering operation.
