Abstract
By measuring speeds and deflection angles of two front wheels in real time, and according to values of gravity sensors at four wheel axles, and an axle base and a wheel base of an automobile, a center of gravity of the automobile is determined; moving speeds of the left and right front wheels of the automobile around an instantaneous center during cornering are converted into moving speeds at the center of gravity of the automobile respectively, and an average value of the two automobile speeds at the center of gravity of the automobile is taken as an actual driving speed of the vehicle during cornering; meanwhile, an automobile speed may be controlled according to force conditions of four wheels.
