Abstract
In an electric-mileage learning when a running mode of a plug-in hybrid vehicle is a CD mode, acquisition of information for the electric-mileage learning is not performed in the case where the running mode is changed from the CD mode to a CS mode during one trip even when the running mode is changed to the CD mode afterward. The electric-mileage learning is performed by calculating a trip electric mileage using only information acquired in the CD mode before a change to the CS mode for the first time. This avoids inclusion of an error caused by running on the uphill road in the CS mode in a learned electric mileage even when the running is performed. This enhances the accuracy of the learned electric mileage, thus accurately calculating a possible EV running distance.
