摘要： A steering control device in which a steering portion including an electric steering reaction force actuator and a steered portion including an electric steered portion actuator are mechanically disconnectable and connectable via backup means. A steer-by-wire control means is provided for disconnecting the backup means and performing steer-by-wire control using control of the steered portion actuator to set a steered angle corresponding to the steering condition and using control of the steering reaction force actuator to add a steering reaction force corresponding to the steered condition. A steering assistance control means is also provided for connecting the backup means and performing steering assistance control by adding a steering aid force using at least one of the steering reaction force actuator and the steered portion actuator. The power supply capacity of a steered vehicle is selectively estimated and if the estimated power supply capacity reaches a predetermined value or below during the steer-by-wire control, steering is switched to the steering assistance control.

摘要： In steering system and method for an automotive vehicle, a reaction force actuator is configured to provide a steering reaction force for the operation inputting section on the basis of a reaction force command value which accords with a state of steerable wheels, a steering actuator is configured to drive the steering mechanism on the basis of a turning angle command value which accords with a steering angle of the operation inputting section, a turning angle correction value setting section sets a turning angle correction value on the basis of the reaction force command value, and a turning angle command value correcting section subtracts the turning angle correction value from the turning angle command value, the turning angle correction value being set in such a manner that, as the reaction force command value becomes larger, the turning angle correction value becomes larger.
摘要翻译：在用于机动车辆的转向系统和方法中，反作用力致动器被构造成基于与可转向轮的状态相对应的反作用力指令值为操作输入部提供转向反作用力，构造转向致动器基于与操作输入部的转向角相一致的转角指令值来驱动转向机构，转向角修正值设定部根据反作用力指令值设定转弯角修正值，转弯指令值修正部从转动角度指令值中减去转动角度修正值，转动角度修正值被设定为随着反作用力指令值变大，转动角修正值变大。
