Simulation and model verification of a vehicle handling dynamics

The purpose of this study is to model, simulate and verify the entire vehicle handling dynamics of UNS Electric vehicle (Semar-T) using Matlab-Simulink. The modeling of Semar-T electric vehicle begins from the derivation equation of motion and Dugoff tire model. The equations are derived using Second Newton´s Law and then simulated in Matlab-Simulink environment. Five handling condition tests are performed for exploring the handling performance namely step steer test, double-lane change test, slalom test, sudden braking test and sudden acceleration test. The disturbances input come from the lateral and longitudinal direction. Disturbance in the lateral direction is steer input while disturbances in the longitudinal direction are braking and throttling. The steering, braking and throttling input in this study is taken from the verification software namely CarSimEd. The results of the validation show that the vehicle model is valid based on verification using CarSimEd with the error magnitude between 5-15 % Therefore, the results of simulation from Matlab-Simulink can be applied to studies the behavior handling dynamics of Semar-T electric vehicle.
