Claim:
1. 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 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 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 to decrease the torque of the motor at a higher rate with an increase in rotation speed or rotational acceleration of the engine at a time when the predetermined condition is satisfied.
