Abstract:
A hybrid vehicle control ECU calculates an estimated EV travelable distance based on a minimum travel cost and a usable charge amount of a battery, when a next external charge point, at which an external power source is available for charging, is set. The minimum travel cost indicates a minimum value of electric power amount consumed by a battery when a vehicle travels a unit distance. If the estimated EV travelable distance is longer, electric motor travel is selected estimating that it is possible to reach the next external charge point. If a remaining distance is longer and a present SOC is higher than a usable SOC lower limit, hybrid travel is selected. If the present SOC is lower than the usable SOC lower limit, a constant SOC travel is selected.
