Hybrid vehicle

A hybrid vehicle comprising:

• an engine;
• a motor generator;
• and
• an electronic control unit configure to control the engine and the motor generator,
• wherein, when an engine speed thereof is increased, the electronic control unit calculates an engine torque by adding an engine inertia torque to a request engine torque and cause the engine to output the calculated engine torque, and cause the motor generator to output a reaction torque in response to the request engine torque, and the electronic control unit performs control so that a torque assistance amount exerted by the motor generator is changeable while the engine speed is increased, wherein the electronic control performs control so that the motor generator outputs a torque in a positive direction which is a same as that of a torque output from the engine in a period from when an engine speed increasing assistance starts to when the engine speed increasing assistance ends by the motor generator while the engine speed increases, and after the engine speed increasing assistance by the motor generator ends, the motor generator outputs a torque in a negative direction which is opposite to that of the torque output from the engine.
