| Abstract: | In order to improve the economic characteristic of a parallel hybrid vehicle, a new design scheme is proposed. A parallel hybrid vehicle is driven by a parallel combination of a direct injection spark ignition IC (internal combustion) engine and a DC motor interconnected by a metal pushing belt continuously variable transmission. The conversion of the powers, which are provided by engine and motor, is carried out by a planetary gear. In this paper, the simulation model on the dynamic characteristic of the hybrid vehicle is established using bond graph theory. When the power sources are converted from a DC motor to an IC engine, the control strategy is obtained. The control objectives are that the engine keeps on working along the optimal economy curve or the motor running in a higher efficiency. The research results will be applicable to the design for a parallel hybrid vehicle. |
