PROBLEM TO BE SOLVED: To further improve fuel economy by further raising a use rate of battery power.SOLUTION: A drive control part 8A acquires map information (variety of data files) having at least altitude data, distance data and road data related to a traveling schedule route by using a map information acquisition part 8a, acquires a flat route zone, an uphill route zone and a downhill route zone by calculation on the basis of the altitude data and distance data by a zone route calculation part 8b, predicts a power consumption amount and a regeneration charge amount at a battery on the basis of a calculation result by the zone route calculation part 8b and the road data by a power consumption regeneration prediction part 8c, sets a traveling mode at a motor traveling mode which is obtained by merely a motor up to a regeneration charge expectation zone by a traveling mode setting part 8d when the prediction of regeneration charge is obtained by the power consumption regeneration prediction part 8c, and in the regeneration charge expectation zone, sets the traveling mode at a normal traveling mode which is obtained by an engine and a motor. |
