1. A method for controlling a hybrid vehicle which includes a regenerative system for converting kinetic energy and an engine, comprising the steps of:
- predicting a plurality of points that the hybrid vehicle can reach at a predetermined time, using stored map information;
calculating a probability that the hybrid vehicle reach each one of the points;
calculating a distribution of elevations that the hybrid vehicle can reach at the predetermined time; and
controlling the regenerative system and the engine based on the distribution of elevations.

Abstract
In a vehicle equipped with an engine and a regenerative system, the quantity of energy storage by the regenerative system is scheduled, and fuel efficiency and driving ease are controlled. If the destination of a vehicle and a route to reach it are not indicated, automatic scheduling is performed. Vehicle scheduling is performed by predicting the distribution of height positions the vehicle is predicted to reach at future points of time and using the representative value of the height at each point of time.
