Abstract: Taking driverless formula car as the research object, the vehicle dynamics modeling is studied based on MATLAB/Simulink, and the car 3-DoF kinematics mathematical model and dynamics mathematical model are deduced. According to the 3-DoF mathematical model combined with Dugoff tire formula and tire rotation calculation formula, the 7-DoF car dynamics model is derived. The car simulation mathematical model is established in MATLAB/Simulink, and the simulation results of input constant front wheel angle and initial speed are verified, and a test platform is established for the design and test of driverless formula car.
