Abstract
A controller for a hybrid electric vehicle includes processing circuitry configured to execute a manual filter regeneration process when satisfying a condition including that execution of the manual filter regeneration process is requested to decrease a PM deposit amount on the filter and that the hybrid electric vehicle is in a stopped state. In the manual filter regeneration process, when a state of charge of the battery becomes less than a discharge threshold value, an output of an internal combustion engine is converted to electric power for charging the battery while the filter is supplied with oxygen from the engine. Further, when the state of charge of the battery becomes greater than or equal to a charge threshold value that is greater than or equal to the discharge threshold value, an output shaft of the engine is rotated with the motor to supply the filter with oxygen from the engine.
