  3. Abstract:
  4. This paper aims to establish a control strategy for parallel hybrid electric vehicles equipped with full-toroidal Continuously Variable Transmission (CVT). First, the advantages of CVT are elucidated. Afterwards, a modified control strategy on the base of Baseline static Control Strategy (BCS) is proposed. Employing this strategy, in some moments, the engine operates in its fuel-optimal point to decrease the vehicle Fuel Consumption (FC). It is demonstrated that the modifications in BCS are applicable using a CVT as the power train. In order to investigate the implemented modification, an optimization on the proposed control strategy and BCS in SC03 driving cycle is accomplished and then, the optimized control strategies are compared. It will be demonstrated that the proposed method is superior to BCS in terms of FC in SC03 driving cycle. Finally, in order to examine generality of the comparison, the optimized control strategies are compared in other driving cycles. It is revealed that the optimized state of the proposed control strategy is advantageous in these cycles
