Plug-in hybrid vehicles

The present invention relates to a plug-in hybrid vehicle. In the case of plug-in hybrid vehicle driving mode is CD mode, electric power consumption rate of learning, when the accumulated driving time in a stroke of the engine reaches a predetermined time (step ST7 is "YES"), so that the current accumulated value and accumulated trip travel distance power consumption value is invalid (step ST10), and does not reflect the current stroke learning in electric power consumption rate. This avoids driving on is uphill or downhill learned by the electric power consumption rate in the case includes an error due to obtain information relating to the electric power consumption and a travel distance in a case where the engine is driven due to, the learned improve the accuracy of the power consumption rate, and accurately calculate an EV travelable distance.
