The recent environmental interests and concerns have an effect on the entire vehicle industry. Since the regulations like limiting the emission of greenhouse gases take into effect, people are more interested in green vehicles such as hybrid vehicle, electric vehicle, and fuel cell vehicle for they emit less greenhouse gases than conventional vehicle. Especially, hybrid vehicle is the most commercialized vehicle among green cars. The maximum velocity and the acceleration characteristic of a vehicle are important factors to figure out the performance of the vehicle. Driving real vehicle adjusting parameters like mass, frontal area, etc. may be accurate. However, this method costs highly and readjusting parameters may take too much time. So using programs and simulating the vehicle model may save time and money. In this study, hybrid vehicle will be modeled using MATLAB Simulink and the dynamic characteristics of the vehicle will be figured out considering some conditions. The type of hybrid vehicle model will be 6-wheel series hybrid combat vehicle using In-Wheel motor. The forces acting on the vehicle were calculated to figure out the dynamic characteristics of vehicle. Tractive force from each motor in each wheel can be calculated and resistive force such as drag resistance, rolling resistance, and slope resistance can also be calculated. After calculating net force on the vehicle, instantaneous acceleration and velocity can be obtained. The maximum velocity of the vehicle can be calculated when the resistance force and tractive force are equal during process of feedback of instantaneous velocity. If there are errors between characteristic of Simulink model and real model, discussions will be added.
