Patent ID: 7832512

Claim:
A hybrid vehicle that includes an internal combustion engine and a first electric motor that transmit a power to a drive wheel via a power transmission mechanism, and can set to a motor travel mode in which the hybrid vehicle travels using only the first electric motor as a drive power source, switches the motor travel mode to an internal combustion engine travel mode in which the hybrid vehicle travels using the internal combustion engine as a main drive power source when a cumulative value of a stop history of the internal combustion engine reaches a predefined upper limit value during the motor travel mode, the hybrid vehicle comprising: a second electric motor that is coupled to an output shaft of the internal combustion engine and capable of generating electricity by receiving a drive power of the internal combustion engine; an electric storage device for being charged by the electricity generated from the second electric motor; a drive device for driving the first electric motor and the second electric motor by using the electricity from at least the electric storage device; a lubricant oil supply device for being coupled to the output shaft of the internal, combustion engine and supplying lubricant oil to at least the power transmission mechanism; a parking brake detecting device for detecting that a parking brake applying a braking force to the drive wheel is activated; a parking range detecting device for detecting that a shift to a parking range is executed; a drive termination operation detecting device for detecting that a drive termination operation is executed by a driver; and a control device for driving the drive device to rotate the output shaft using the second electric motor, operating the lubricant oil supply device using the second electric motor, and resetting the cumulative value of the stop history of the internal combustion engine when one of a condition under which the parking brake is activated, a condition under which a shift to the parking range is executed, and a condition under which the drive termination operation is executed is satisfied during the motor travel mode.
