A 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 includes 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, including: 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.
