Abstract:
A vehicle steering device includes an electric motor applying a steering force to a vehicle turning mechanism, a first setting portion setting a target assist torque in accordance with a steering torque, a second setting portion setting an angle controlling target torque for bringing an angular deviation between a target steering angle and an actual steering angle close to zero, a restriction processing portion restricting the angle controlling target torque set by the second setting portion, a first calculating portion calculating a target automatic steering torque using the angle controlling target torque after the restriction process by the restriction processing portion, and second calculating portions performing 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 electric motor target motor torque value.
