摘要： An ECU acquires a steering torque detected by a torque sensor (step S1). The ECU drives an electromagnet of a solenoid actuator (step S2). The ECU drives a steering operation motor in accordance with the direction of the detected steering torque acquired in step S1 to apply, to an output shaft of a clutch, a torque acting in such a direction that a torque being exerted on a clutch mechanism is reduced (step S3). When a predetermined time has elapsed since driving of the steering operation motor in step S3 (step S4: YES), the ECU 40 reverses a driving direction of the steering operation motor to apply, to the output shaft of the clutch, a torque acting in a direction opposite to the direction of the last torque applied (step S5).

摘要： A steering apparatus is provided which can suppress unintended movement of a steering wheel when a clutch is engaged. When a power switch (54) is turned off and a steering wheel (11) is steered, a reaction force control circuit (33) makes a reaction force motor (31) to generate a steering reaction force stronger than a normal steering reaction force in order to give a driver an appropriate feeling of response according to a steering torque (τ). The strong steering reaction force is applied to a steering shaft (12) to suppress steering of the steering wheel (11). A steering operation control circuit (44) executes steering operation control, that is, control that makes an actual steered angle (θt) equal to a target steered angle based on a steering angle (θs), and then a clutch (21) is engaged. The clutch (21) is engaged after confirmation of an immovable state of steered wheels (16), (16), and thus rotation of the steering wheel (11) unintended by the driver is suppressed.
摘要翻译：提供了一种转向装置，其能够抑制当离合器接合时方向盘的意外运动。当电源开关（54）断开并且方向盘（11）转向时，反作用力控制电路（33）使反作用力电动机（31）产生比正常转向反作用力更强的转向反作用力以根据转向扭矩（τ）给驾驶员适当的响应感觉。强大的转向反作用力施加到转向轴（12）以抑制方向盘（11）的转向。转向操作控制电路44执行转向操作控制，即基于转向角（θs）使实际转向角（θt）等于目标转向角的控制，然后离合器（21）接合。在确认了转向车轮（16），（16）的不可移动状态之后接合离合器（21），并且因此驾驶员不希望的方向盘（11）的旋转被抑制。
