Hybrid vehicle

A hybrid vehicle, comprising:

• an engine that is configured to have an output shaft that is connected via a torsion element with a downstream shaft linked with an axle;
• a motor that is configured to input and output power from and to the downstream shaft;
• a battery that is configured to transmit electric power to and from the motor;
• and
• a controller that is configured to, in a process of cranking and starting the engine by the motor, control the motor such as to increase a torque of the motor from value 0 to a specified torque and keep the torque at the specified torque until a predetermined condition is satisfied that a rotation speed of the engine is equal to or higher than a predetermined rotation speed and a crank angle of the engine is in a predetermined crank angle range, and to control the motor such as to decrease the torque of the motor from the specified torque after the predetermined condition is satisfied, wherein
• after the predetermined condition is satisfied, the controller controls the motor such as to decrease the torque of the motor at a higher rate with an increase in time period between start of cranking the engine and satisfaction of the predetermined condition.
