[Problem] An object of the present invention is to provide a vehicle steering angle detecting apparatus and an electric power steering apparatus equipped therewith having reasonable price that estimate a motor shaft angle and a steering shaft angle with a high accuracy by learning nonlinear elements, and can back up both angle sensors by utilizing estimating angles of the both angle sensors. [Means for solving the problem] The present invention is the vehicle steering angle detecting apparatus that connects a motor, which assist-controls a steering system of a vehicle, to the steering shaft via a reduction mechanism, and comprises the first angle sensor which detects the steering shaft angle of the steering shaft and the second angle sensor which detects the motor shaft angle of the motor, comprising: a function that updates a static characteristic map and a dynamic characteristic map by iteratively learning a static characteristic and a dynamic characteristic of the nonlinear elements including the reduction mechanism, and mutually estimates the steering shaft angle and the motor shaft angle by using the static characteristic map and the dynamic characteristic map. The present invention is also the electric power steering apparatus equipped with the vehicle steering angle detecting apparatus.
