Abstract: A controller for an engine includes processing circuitry configured to perform fuel cut-off for regenerating the filter by burning fine particulate matter collected in the filter. The processing circuitry is configured to perform an interruption process for interrupting the fuel cut-off in a case in which warming of the passenger compartment is requested when the fuel cut-off is being performed and an engine coolant temperature, which is a temperature of the engine coolant, becomes lower than or equal to a predetermined temperature after the fuel cut-off is started.

Abstract: A controller includes an engine controlling section and a motor-generator controlling section. The controller is configured to use the engine controlling section and the motor-generator controlling section to execute an intermittent stop control, a temperature increase control, an intermittent stop prohibition control, and a motoring control. The intermittent stop control automatically stops and restarts operation of an internal combustion engine. The temperature increase control increases the temperature of a filter in the exhaust passage to a temperature at which PM can be burned. The intermittent stop prohibition control prohibits stop of the operation of the internal combustion engine by the intermittent stop control until the temperature increase control is completed. The motoring control drives the output shaft of the internal combustion engine by the motor-generator, thereby forcibly rotating the internal combustion engine.
