The invention provides a vehicle cornering time optimization algorithm. As a driver firstly gives a control turning angle according to the running road profile and motion state of a vehicle, the motion state of the vehicle in running is obtained by a vehicle-mounted sensor; direction deviation and lateral displacement deviation between a vehicle running trajectory and a track center line are obtained by a Kalman filter according to the motion state of the longitudinal vehicle in running on the basis of predetermined rules; an additional turning angle is obtained by a controller according to the motion state, direction deviation and lateral displacement deviation on the basis of the optimal control algorithm; and the optimal turning angle of front wheels of the vehicle is determined by both the control turning angle and the additional turning angle. According to the invention, the optimized turning angle is obtained through computation, so that the vehicle turns a corner in a shorter time. Thus, the time for a racing driver to complete the whole race is shortened, and a good grade is achieved.
