In a conventional hybrid scheme used to mount a rechargeable battery in a motor vehicle, store into the battery the electric power that has been obtained via a regenerative brake, and utilize the power during acceleration of the vehicle, when a temperature rise of the battery due to charging or discharging causes a temperature of the battery to stay outside a defined range, it has been absolutely necessary to stop the battery charge or discharge, and fuel efficiency has decreased. This invention predicts a charge level and temperature of a rechargeable battery from the cruising input/output power requirements calculated from route information and historical records of cruising, prevents a stoppage of the battery by calculating chronological engine output and brake control data for the temperature to stay within a defined range, and hence improves fuel efficiency.
