Advanced VDC simulations of In-wheel electric vehicle using Carsim and Simulink

Conventional engine based vehicles inevitably have complicated structures due to lots of elements. Because of this characteristic, research, development, and also marketing are mainly conducted by the conglomerate, like GM, BMW, Honda, and Hyundai motors, etc. But environmental pollution and fuel exhaustion by the stated vehicle increase the necessity of EV(Electric Vehicle) as a representative of green car. First of all, the structure of EV is relatively simple, and energy transmission ratio of electric motor is more efficient than the engine based power train system. In addition to these, inwheel EV can estimate exact wheel torque, which is the most fundamental information for slip control, such as VDC(Vehicle dynamics control)/TCS(Traction control system)/ABS(Anti-lock brake system). Various kinds of expectable situations during EV’s navigation have been simulated through the coordination between ‘Carsim’ and ‘Simulink’.
