Abstract
A turning control device includes a first processor, a second processor, a third processor, and a fourth processor. The first processor calculates a torque command value based on a difference between a target pinion angle and a pinion angle. The second processor calculates a compensation value compensating resistance of a turning mechanism based on a difference between a target pinion angular velocity and a pinion angular velocity. The third processor limits a variation range of the torque command value based on a limit value of the torque command value and limits a variation range of the compensation value based on a limit value of the compensation value. The fourth processor calculates a turning torque command value by subtracting the compensation value from the torque command value. The third processor changes the limit values based on a traveling state of a vehicle.
