This steer-by-wire steering input device is provided with: a steering shaft mechanically separated from a steered wheel; a reaction force motor that applies a steering load to the steering shaft; a lock mechanism that restricts rotation of the steering shaft; a steering amount sensor that detects an operation amount of the steering shaft and outputs an operation amount signal; and a controller that increases a reaction torque generated by the reaction motor after the start switch of the vehicle is switched to the OFF state, and switches the lock mechanism to the locked state after the reaction torque is increased. As a result, when the start switch of the vehicle is switched to the OFF state, the occurrence of phase deviation between the steering wheel and the steered wheel can be suppressed, and discomfort during steering by the driver can be suppressed.
本发明的线控转向的转向输入装置具备:与转向轮机械地分离的转向轴;对转向轴赋予转向负载的反作用力马达;限制转向轴的旋转的锁定机构;检测转向轴的操作量并输出操作量信号的转向量传感器;以及控制器,控制器在车辆的起动开关切换为断开状态之后,使反作用力马达产生的反作用力扭矩增大,进而在反作用力扭矩增大之后,将锁定机构切换为锁定状态。由此,在车辆的起动开关被切换为断开状态时,能够一边抑制产生方向盘与转向轮的相位偏差一边抑制驾驶员的转向时的不适感。
