摘要： Under an automatic turning control, a steering controller defines a value of steering angle set according to a target turning angle of the automatic turning control, as a value of steering angle at which a reaction force is equal to 0. Thereby, the steering controller controls a steering reaction force on the basis of a difference between an actual steering angle and the value of steering angle at which the reaction force is equal to 0.

摘要： A vehicle steering controller produces a steering system friction value and a tire lateral force value. A steering reactive force having a magnitude based on the tire lateral force value and the steering system friction value is generated for application to a steering wheel of the vehicle. By reflecting both the tire lateral force and the steering system friction in the steering reactive force, a good steering sensation can be realized in a steer-by-wire system.

摘要： 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.
