Hybrid electric vehicle

A hybrid electric vehicle comprising:

• an engine;
• a motor provided on a power transmission path between the engine and a drive wheel and configured to generate electric power by receiving rotational power of the engine;
• a torque converter provided on the power transmission path between the motor and the drive wheel and including a lock-up clutch;
• an automatic transmission provided between the torque converter and the drive wheel;
• a battery to be charged with generated electric power of the motor;
• and
• a control device, wherein
• the control device includes:
• a determination unit configured to determine whether the engine is in a driven state, the hybrid electric vehicle is in a stopped state, the automatic transmission is in a D range, and the lock-up clutch is in a released state;
• a setting unit configured to, when affirmative determination is made by the determination unit, set a target idle speed that is a target rotation speed in an idle operation state of the engine to a higher value as requested charging power of the battery increases;
• and
• a control unit configured to, when the engine is in the idle operation state, control the engine to reduce an increase rate for increasing an engine speed toward the target idle speed as the engine speed increases.
