Abstract:
1. A hybrid vehicle comprising: an internal combustion engine capable of outputting power for driving the vehicle; a motor capable of outputting power for driving the vehicle; an accumulator capable of supplying electric power to the motor; a fuel consumption priority mode selection switch to select a fuel consumption priority mode that gives priority to fuel consumption; an accelerator operation amount detecting unit configured to detect an accelerator operation amount by a driver; an accelerator operation determination module configured to determine whether or not a driver's accelerator operation is rough in accordance with the detected accelerator operation amount; an engine start condition setting module configured to set a start condition of the internal combustion engine to a first condition when the fuel consumption priority mode selection switch is turned off during a driving without an operation of the internal combustion engine, the engine start condition setting module setting the start condition to the first condition when the accelerator operation determination module determines that the driver's accelerator operation is not rough and the fuel consumption priority mode selection switch is turned on during the driving without the operation of the internal combustion engine, the engine start condition setting module setting the start condition of the internal combustion engine to a second condition giving priority to fuel consumption in comparison with the first condition when the accelerator operation determination module determines that the driver's accelerator operation is rough and the fuel consumption priority mode selection switch is turned on during the driving without the operation of the internal combustion engine; a driving force demand setting module configured to set a driving force demand required for driving the vehicle; and an engine stop driving control module configured to control the internal combustion engine and the motor so that a driving power equivalent to the set driving force demand is ensured without a start of the internal combustion engine when the set start condition is not satisfied during the driving without the operation of the internal combustion engine, the engine stop driving control module controlling the internal combustion engine and the motor so that the driving power equivalent to the set driving force demand is ensured with the start of the internal combustion engine when the set start condition is satisfied during the driving without the operation of the internal combustion engine.
