Abstract

An energy supply amount control system may be applied, for example, to a hybrid vehicle using two ore more energy sources such as gasoline and electricity (motor). The energy supply amount control system includes route search means and energy cost calculation means. The energy cost calculation means detects a section where electric energy can be regenerated on a route searched by the route search means. The energy cost calculation means calculates a cost (fare) required when the motor alone is used for travelling in a section other than the detected section and a cost (fare) required when the motor and the gasoline are both used for travelling. The costs (fares) are represented to a user and the energy selected by the user is supplied by the energy supply amount control means.
