Abstract
When an ignition key is turned ON, a control apparatus predicts the arrival time to a chargeable location (such as home). When the control apparatus determines that the expected arrival time is in the nighttime, it sets SOC control upper and lower limit values for an EV traveling-importance mode that are lower than SOC control upper and lower limit values for an HV traveling-importance mode, and controls an SOC of a battery based on the upper and lower limit values.

3. A hybrid vehicle incorporating an internal combustion engine and a rotating electric machine as its motive power sources, comprising:
-
an electric power storage apparatus capable of being charged and discharged and supplying electric power to said rotating electric machine; an electric power input portion receiving electric power provided from a source external to the vehicle for charging said electric power storage apparatus; an electric power generation apparatus generating electric power using an output from said internal combustion engine and supplying the generated electric power to said electric power storage apparatus; control means for controlling a state of charge of said electric power storage apparatus to attain a prescribed control range or control target value; and prediction means for predicting an arrival time to a location where said electric power storage apparatus can be charged from said electric power input portion, said control means setting, when the arrival time predicted by said prediction means is included in a specified time slot where an electricity price is relatively inexpensive in a day, said prescribed control range or control target value to be lower than when said arrival time is included in a time slot other than said specified time slot. - View Dependent Claims (4, 5, 6, 7, 15, 16, 17)

10. A controlling method of a hybrid vehicle incorporating an internal combustion engine and a rotating electric machine as its motive power sources, said hybrid vehicle including:
-
an electric power storage apparatus capable of being charged and discharged and supplying electric power to said rotating electric machine; an electric power input portion receiving electric power provided from a source external to the vehicle for charging said electric power storage apparatus; and an electric power generation apparatus generating electric power using an output from said internal combustion engine and supplying the generated electric power to said electric power storage apparatus, said controlling method comprising; a first step of predicting an arrival time to a location where said electric power storage apparatus can be charged from said electric power input portion; a second step of setting, when the predicted arrival time is included in a specified time slot where an electricity price is relatively inexpensive in a day, a control range or control target value of a state amount representing a state of charge of said electric power storage apparatus to be lower than when said arrival time is included in a time slot other than said specified time slot; and a third step of controlling said state amount to attain said control range or control target value. - View Dependent Claims (11, 12, 13, 14, 18, 19, 20)
