In order to analyze the compensation relationship between adjustment quantity and track deviation, and solve the problem of high-deviation of the track, the carbon-free car whose running track approximates to a sine curve is taken as the research object. Firstly, the mathematical model of car motion is established, then the two main causes of the track deviation were concluded. By the premise that the error of departure angle is eliminated, the length of guide-bar is adjusted by screw pair to compensate the ultimate angle error of the steering shaft. Finally, the virtual prototype model of carbon-free car is established and the proper adjustment quantity is set. The experiment verifies the effectiveness and correctness of the proposed model and method.
