摘要： PROBLEM TO BE SOLVED: To provide a vehicular steering device allowing the stop of a steering wheel at an end position without abutment between stoppers and the holding of the steering wheel at the end position. SOLUTION: A controller stops a PS motor when the tire angle of the steering wheel detected by a tire angle sensor corresponds to an end angle. Thus, the steering wheel is stopped at the end position. In this holding control, whether the tire angle corresponds to the end angle or not is determined (S22). When the steering wheel is shifted from the end position to a forward side in spite of a handwheel not being operated by outer force applied to the steering wheel, the PS motor is driven so that the steering wheel is turned to the direction of returning to the end position, opposite to the forward side (S23, S24). On the other hand, when the steering wheel is moved excessively far to the end direction beyond the end position, the PS motor is driven so that the steering wheel is turned to the forward side (S23, S25).
摘要翻译：要解决的问题：提供一种车辆转向装置，其允许在端部位置处停止方向盘，而不会在止动件之间停止并且使方向盘在端部位置处的保持。解决方案：当由轮胎角度传感器检测到的方向盘的轮胎角度对应于端角时，控制器停止PS电动机。因此，方向盘停止在结束位置。在该保持控制中，确定轮胎角度是否对应于终止角度（S22）。尽管手轮没有被施加到方向盘的外力操作，方向盘从端部位置移动到前方，但是驱动PS电动机使得方向盘转向返回到方向盘的方向（S23，S24）相对。另一方面，当方向盘向终端方向移动得超过结束位置时，PS电动机被驱动，使得方向盘转向前方（S23，S25）。
