Abstract

A hybrid control device calculates engine rotational speed and engine torque based on cooling water temperature for an engine and a charging state of a main battery. The hybrid control device operates the engine in a maximum charging efficiency mode, when the cooling water temperature is lower than a target temperature value and the main battery has a remaining charging capacity. In the maximum charging efficiency mode, the hybrid control device calculates such engine rotational speed and engine torque, which realize engine operation according to which a fuel consumption amount for a unit amount of charging electric power is minimized. As a result, efficiency of a vehicle control system is improved as a whole, to thereby improve fuel consumption ratio.
