| Summary: | In order to study the capability of Continuously Variable Transmission (CVT)
system, a model of High Mobility Multipurpose Wheeled Vehicle (HMMWV)
is derived and carried out in the Matlab-Simulink environment. The model
consists of vehicle dynamic system, wheel dynamic system, powertrain system
and tire traction system where the performance of vehicle model is compared
between a stepped Automatic Transmission (AT) and CVT system equipped to
the vehicle. The model is verified using CarSim results where the developed
model shows a similar trend with minor deviation. A new electro-mechanical
CVT system has been proposed to overcome the drawbacks of the current CVT
system. Then, the developed vehicle model is implemented with vehicle speed
control to study the performance of the vehicle with both transmission systems.
Comparison between AT and CVT systems indicate that vehicle with CVT
system shows a superior performance with higher acceleration performance
and lower fuel consumption. |
