ABSTRACT:
An electric power steering device which includes a sample reliability level calculation device for calculating a reliability y of a sampling value θaas a neutral angle θcbased on a vehicle speed V, a angular velocity ω, a steering torque T, and relating values of the vehicle speed V, the angular velocity ω of the steering angle, and the steering torque T when a sampling condition is established. The neutral angle estimation means temporarily determines, confirms, or renews the value of the neutral angle θcbased on the sampling value θaand the reliability level y.
