<P>PROBLEM TO BE SOLVED: To improve the whole system efficiency in the hybrid vehicle at an engine cold state. <P>SOLUTION: The hybrid vehicle 100 includes: an engine 1 that transmits the torque to a wheel driving shaft 63a; a motor generator 5 that transmits the torque to the wheel driving shaft 63a; and a controller that controls the engine 1 and the motor generator 5. When the engine 1 is in a cold state and the vehicle requested torque is the torque lower than the operational area A of 95% of the fuel consumption rate of the engine 1, the controller operates the engine 1 in the operating condition included in the operational area A of 95% of the fuel consumption rate by adding the surplus torque to the vehicle requested torque, and performs power generation by driving the motor generator with the surplus torque. <P>COPYRIGHT: (C)2013,JPO&INPIT |
