In this paper, to minimize the fuel consumption in a vehicle equipped with a CVT transmission system, by
taking in to account the power losses in the system components, a new comprehensive optimal control strategy
is presented. According to the vehicle dynamic model, formulation of the problem leads to an optimal
control problem which has been solved using Bellman’s dynamic programming method. In order to evaluate
the efficiency of the method, the optimal control strategy is applied to an Iranian vehicle, Pride, which
is theoretically equipped with the CVT transmission system, and its fuel consumption is evaluated in some
parts of a standard driving cycle, NEDC. Then the fuel consumption of the vehicle with manual transmission
is calculated in the same driving cycle and is compared with the case in which it is equipped with the
CVT. Results show that the fuel consumption of the vehicle with an optimally controlled CVT is considerably
less than that of the vehicle with manual transmission.
