Abstract: A vehicle steering system is disclosed that includes a steering portion, a steered portion, and a clutch mechanism. The steering portion includes operations input mechanism and a reaction adding device. The steered portion includes steering controlled wheels and a steered force adding device. The clutch mechanism mechanically connects the steering portion and steered portion through an engagement. The clutch mechanism has a permanent magnet and an electromagnetic coil so as to form an electromagnetic clutch that releases when a current is applied such that a magnetic force in the direction that cancels a magnetic force of the permanent magnet is generated for the electromagnetic coil. The electromagnetic clutch engages when a current is not applied to the electromagnetic coil. The vehicle steering system further includes a controller that generates the magnetic force in the same direction as the magnetic force direction of the permanent magnet for the electromagnetic coil when an abnormality is generated for the steering system.

Abstract: A steering controller is provided for use in a steering system in which a steering unit having a steering wheel 6 and a reaction motor 5 and a direction varying unit having steered wheels 16,16 and a direction varying motor 14 are mechanically disconnected from each other. Here, the steering controller performs: a direction varying torque control process for outputting a control command for applying a direction varying torque to the direction varying unit in accordance with the steering status of the steering wheel 6 to the direction varying motor 14; a steering reaction control process for outputting a control command for applying a steering reaction torque to the steering unit in accordance with the direction varying status of the steered wheels 16,16 to the reaction motor 5; and an control process for giving an end contact feeling to a driver through the steering wheel 6 the vicinity of a turning limit is reached. In the contact control process, when a direction varying angle of the steered wheels 16,16 reaches the vicinity of the maximum direction varying angle, correction of the steering reaction torque applied in the steering reaction control process is started and the steering reaction torque is gradually increased with the lapse of time after the beginning of correction.
