1. A hybrid electric vehicle, comprising:
an engine;
a filter that collects particulate matter from the engine;
a motor located on a power transmission path between the engine and a drive wheel;
a torque converter located on the power transmission path between the motor and the drive wheel and including a lock-up clutch;
a battery that supplies power to the motor; and
a control device,
the control device configured to:
determine whether there is a request for regeneration control of the filter by a fuel cut in the engine,
determine whether the lock-up clutch is not engageable,
determine whether the motor is able to assist with the rotation of the engine, based on at least one of the following values of the battery: a temperature, a voltage, and a level of charge, and
in a case where the control device determines that there is the request for regeneration control, the lock-up clutch is not engageable, and the motor is able to assist with the rotation of the engine, disengage the lock-up clutch and perform auxiliary regeneration control with the motor assisting with rotation of the engine while performing the fuel cut.
