Abstract
Along with detecting speed of a hybrid vehicle, a drive/brake power command value for the vehicle is set, and an efficiency indication which indicates the efficiency of fuel utilization is also set. An operational point for an internal combustion engine and an electric motor of the vehicle is determined which makes the amount of charge into a battery smaller, the greater is this efficiency indication, based upon the detected vehicle speed, and the drive/brake power command value and the efficiency indication. In this manner, it is possible to control the engine and the motor so as to bring the remaining amount of charge in the battery to a target value while keeping the fuel consumption over the route to be travelled as low as possible.
