PROBLEM TO BE SOLVED: To control frequent happenings of switching of control based on a control map according to fluctuation of the real electricity accumulation quantity, when the accumulation possible capacity of electricity decreases along with deterioration of an electric storage device.SOLUTION: A change to integrate at least one area into other areas according to deterioration of an electric storage device is done to a control map that defines right or wrong of execution of one or more controls that is defined for each of at least two or more areas related to the electrical charge and discharge of the electric storage device. In a word, the area is thinned out. Since discrimination of the area is carried out based on the real accumulation of electricity quantity of the electric storage device, and control to be executed is decided according to right or wrong of execution defined for the discriminated area, even if the accumulation possible electricity capacity decreases according to the deterioration of the electric storage device, the switching of the control according to the coming and going between areas based on the fluctuation of the real accumulation of electricity quantity becomes difficult to cause by the thinning of the area. Thus, in a hybrid vehicle that is provided with an electric motor in addition to an internal combustion engine as a driving source, frequent occurrence of switching of control is suppressed when the accumulation possible electricity capacity deteriorated caused by deterioration of the electric storage device. |
