摘要： A vehicle steering device, in which a steering member and a steering operation mechanism are not mechanically coupled, includes a reaction force motor (19) that applies a reaction force to the steering member, and a reaction force motor control unit (70) that controls the reaction force motor. The reaction force motor control unit (70) includes a target rotational angle setter (71) that sets a target rotational angle for an output shaft at a position close to the side of the neutral position of the output shaft with respect to the rotational angle of the output shaft corresponding to a steered angle limit value by a rotational angle matching steering torque detected by a torque sensor (16) when a steered angle has reached the steered angle limit value and the steering torque that is larger than the steering torque at the time when the steered angle limit value was reached is applied to a steering wheel.

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： Influence on a sensor due to leakage magnetic flux from a clutch that connects and disconnects a steering force transmission path is effectively reduced. A steering system includes a clutch (50) that is disposed in a steering force transmission path between a steering wheel (10) and steered wheels (16) and that mechanically disconnects the steering force transmission path when energized, and mechanically connects the steering force transmission path when de-energized, and a an upstream sensor (21) and a downstream sensor (22) each of which detects at least one of a steering torque and a steering angle in the steering force transmission path. At least one of the upstream sensor (21) and the downstream sensor (22) detects an energization status of the clutch (50). A detected value of at least one of the steering torque and the steering angle is corrected using a first correction value when the clutch (50) is energized, and the detected value of at least one of the steering torque and the steering angle is corrected using a second correction value different from the first correction value when the clutch (50) is de-energized.

摘要： An electric power steering apparatus 1 drives a motor 4 to generate a steering assist force according to a steering torque and includes an output circuit 21 for supplying the motor with electric power from at least one of a battery 4 and an auxiliary power supply 7, 8. The electric power steering apparatus has a control circuit 13 which at or after detection of a breakdown of the battery 4, determines a length of time to the end of steering assist (decreasing time t1) based on the amount of energy stored in the auxiliary power supplies 7, 8 and which takes the determined length of time to perform output decreasing control to gradually decrease the upper limit of power supplied for the steering assist to practically zero according to a constant gradient. Thus is provided an electric power steering apparatus which is adapted to prevent a sudden fall of the steering assist force in the event of a battery breakdown while effectively utilizing the available stored energy.
