Abstract
A vehicle steering device includes a first setting portionthat sets a target assist torque in accordance with a steering torque, a second setting portionthat sets an angle controlling target torque for bringing an angular deviation between a target steering angle and an actual steering angle close to zero, an estimator that estimates a compensation objectload with respect to the angle controlling target torque, a first calculating portionthat calculates a target automatic steering torque based on the angle controlling target torque set by the second setting portion and the compensation object load estimated by the estimator, and a second calculating portionthat performs weighted addition of the target automatic steering torque and the target assist torque in accordance with a value that changes in accordance with a driver input to calculate a target motor torque that is a target value of a motor torque of the electric motor.
