Abstract
An electric power steering apparatus that: calculates a steering angle control current command value for the steering angle control based on at least a steering angle command value and an actual steering angle; judges a steering state based on a manual input judgment and performs a switch of the steering state; converts a steering angular velocity command value calculated from at least the steering angle command value and the actual steering angle into an extended steering angular velocity command value; calculates the steering angle control current command value based on the extended steering angular velocity command value and an actual steering angular velocity; performs manual input judgment to a steering torque by using a threshold; and calculates the current command value by using at least the steering angle control current command value.
