Controller for hybrid vehicle

A controller configured to control a hybrid vehicle, the hybrid vehicle having a battery that is charged with power generated by a motor-generator using output of an internal combustion engine, the controller comprising:

• an engine controlling section configured to control the internal combustion engine;
• and
• a motor-generator controlling section configured to control the motor-generator, wherein
• the controller is configured to use the engine controlling section and the motor-generator controlling section to
• execute an intermittent stop control of automatically stopping and restarting operation of the internal combustion engine,
• execute a temperature increase control of increasing the output of the internal combustion engine to increase an amount of generated heat and increasing an amount of power generated by the motor-generator, thereby increasing a temperature of a filter provided in an exhaust passage of the internal combustion engine to a temperature at which particulate matter can be burned,
• execute an intermittent stop prohibition control of prohibiting stop of the operation of the internal combustion engine from when the temperature increase control is started to when the temperature increase control is completed, and
• execute a motoring control of driving an output shaft of the internal combustion engine using the motor-generator on condition that the temperature of the filter is the temperature at which the particulate matter can be burned, thereby forcibly rotating the internal combustion engine.
