WIPO Patent Application WO/2019/087864

Kind Code:

A1

Abstract:

This steering control device (50) is provided with a microcomputer (51) that controls driving of a motor (40). The microcomputer (51) comprises: a basic assist component calculation unit (70) for calculating a basic assist component (Tb*); an angle command value calculation unit (71) for calculating an angle command value (θp*); an angle feedback control unit (72) that calculates an assist command value (Ta*) via angle feedback control in which a pinion angle (θp) is made to follow the angle command value (θp*); and a control signal generation unit (55) that generates a motor control signal (S_m) on the basis of the assist command value (Ta*). The basic assist component calculation unit (70) comprises: a torque command value calculation unit (74) for calculating a torque command value (Th*) that is a target value for steering torque (Trq) to be input by a driver; and a torque feedback control unit (75) that calculates the basic assist component (Tb*) via torque feedback control in which the steering torque (Trq) is made to follow the torque command value (Th*).
