<P>PROBLEM TO BE SOLVED: To suppress fuel consumption by efficiently charging and discharging a battery. <P>SOLUTION: A driving control device for a hybrid vehicle includes: an information memory 14 for storing travel route history information; a selection probability calculation unit 22 for calculating selection probability of a travel route selected in each branch point present from a current location to each destination based on the travel route history information; and an optimum charge and discharge control decision unit 23 for predicting a plurality of travel routes based on the travel route history information, for calculating each destination arrival probability of arriving at each destination from the current location by use of selection probability in each branch point, for setting a charge amount of the battery such that the charge amount of the battery at a time point of the arrival to each destination becomes a prescribed optimum value when traveling through each predicted travel route, for predicting each charge amount of the battery when arriving at the first branch point from the current location, for performing weighting corresponding to the destination arrival probability of the corresponding travel route to each predicted charge amount, and for setting the charge amount of the battery of the first branch point. <P>COPYRIGHT: (C)2011,JPO&INPIT |
