POWER GENERATION SOURCE CONTROL DEVICE AND HYBRID VEHICLE INCLUDING THE POWER GENERATION SOURCE CONTROL DEVICE

摘要

PPROBLEM TO BE SOLVED: To provide a power generation source control device, further improving the fuel consumption of a hybrid vehicle. PSOLUTION: The power consumption in a power supply system is sequentially calculated to set an assist fuel consumption amount Fassi[i] in consideration of the consumption power in the power supply system, and an assist economic index is calculated from the assist fuel consumption amount Fassi[i] (S110). The power consumption in the power supply system is sequentially calculated to set a power generation fuel consumption amount Fgen[i] in consideration of the power consumption in the power supply system, and a power generation economic index Dgen[i] is calculated from the power generation fuel consumption amount Fgen[i] (S112). Thus, since these economic indexes Dassi[i], Dgen[i] are obtained by reflecting change of the power consumption in the power supply system the power transfer amount between a battery and a power generation source is set based on these economic indexes Dassi[i], Dgen[i] in the step S114 to further improve the fuel consumption of the hybrid vehicle.
