VEHICLE STEERING DEVICE

WIPO Patent Application WO/2020/012689

A1

[Problem] To provide a vehicle steering device that is not affected by the condition of a road, that does not vary with changes in the mechanism characteristics of a steering system due to aging, and with which it is possible to easily achieve suitable steering torque in relation to a steering angle, etc. [Solution] A vehicle steering device that performs assistance control of a steering system, wherein the device comprises a target steering torque generation unit that generates a target steering torque, a conversion unit that converts the target steering torque to a target torsion angle, and a torsion angle control unit that calculates a motor current command value so as to cause the target torsion angle to follow the torsion angle. The target steering torque generation unit is equipped with an offset correction unit that derives a first torque signal from characteristics that correspond to the steering angle set on the basis of the offset value of the steering torque, the first torque signal is output as the target steering torque, and the drive of the motor is controlled on the basis of the motor current command value.
