The invention provides torque corrosion coefficient calculation and torque analysis methods and systems for an electric automobile. Besides consideration of motor speeds and opening degrees of an accelerator pedal, speeds of the automobile and fault levels are comprehensively considered to determine correction coefficients and correction starting points of torque, and required torque for system analysis is corrected in real time. When the speeds of the automobile and the fault levels are different and the opening degrees of the accelerator pedal are the same, different torque corrosion coefficients can be obtained, and more accurate toque analysis coefficients are obtained; with the adoption of the scheme, more accurate and more comprehensive consideration factors are provided for actual output torque of a motor, and the torque control precision of the whole automobile is improved.
