The invention discloses a steering wheel rotation angle calculation method based on a TAS angle sensor, which comprises the following steps that: step 1, an internal signal processing state machine module of an angle calculation module checks the validity of each input signal, and calculates whether a rack is in a static state or not; 2, learning the angle of the tail end of the rack; 3, calibrating the center angle of the steering wheel; 4, initializing a rotor angle of the power-assisted motor, and calculating a real-time steering wheel angle and a rack position; and 5, correcting the steering wheel turning angle to obtain a corrected steering wheel turning angle value. The accuracy of the steering wheel return position can be improved, the speed and accuracy of completing advanced functions are improved, and the driving experience of a driver is improved.
