Abstract

This paper studies the simulation, modeling and validation of vehicle longitudinal dynamic system. The data obtained from the studies may be used in developing larger system such as adaptive cruise control (ACC) and antilock brake system (ABS) which used the acceleration and braking as the result to control. The simulation of vehicle longitudinal dynamic use mathematical equation derivation to simulate the model. The step in modeling and derivation of mathematical equation are discussed in this paper. It is consist of engine model, vehicle dynamic, wheel dynamic, longitudinal slip ratio and the pacejka tire model. The modeling is develop in Matlab Simulink software and the validation use the validate software for vehicle which is CarSim software. The parameter use in the modeling is based on Proton Iswara Aeroback parameter but the engine model is used the 75kw engine instead of 55kw original engine by manufacturer. The transmission use the automatic transmission based on the shift-map logic of modern vehicle. We hope that this paper will give information about the simulation of vehicle longitudinal dynamics.
