## Abstract

A vehicle includes: an internal combustion engine; a filter collecting particulate matter contained in exhaust gas of the internal combustion engine; a heater core configured to be able to heat up a vehicle cabin; and an electronic control unit. The electronic control unit is configured to execute regeneration cut control and heating control. The regeneration cut control is a control for regenerating the filter by stopping a fuel supply to the internal combustion engine and supplying oxygen to the filter in a state where an output shaft of the internal combustion engine rotates. The heating control is a control for bringing the internal combustion engine into a combustion state and heating by the heater core. The electronic control unit is configured not to execute the heating control but to execute the regeneration cut control when the heating control is requested and the regeneration cut control is requested.

## Claims

### Claim 1

A vehicle comprising:
an internal combustion engine;
a filter configured to collect particulate matter contained in exhaust gas of the internal combustion engine;
a heater configured to be able to heat up a vehicle cabin by using exhaust heat of the internal combustion engine; and
an electronic control unit configured to execute regeneration cut control and heating control, the regeneration cut control being a control for regenerating the filter by stopping a fuel supply to the internal combustion engine and supplying oxygen to the filter in a state where an output shaft of the internal combustion engine rotates, and the heating control being a control for bringing the internal combustion engine into a combustion state and heating by the heater using exhaust heat of the internal combustion engine, the electronic control unit being configured to execute the heating control when the heating control is requested and not to execute the heating control but to execute the regeneration cut control when the heating control is requested and the regeneration cut control is requested.

### Claim 2 (depends on 1)

The vehicle according to claim 1 further comprising:
a first rotary electric machine connected to the internal combustion engine, wherein
the electronic control unit is configured to stop the fuel supply to the internal combustion engine and make the output shaft of the internal combustion engine rotate by using power of the first rotary electric machine when executing the regeneration cut control.

### Claim 3 (depends on 2)

The vehicle according to claim 2 further comprising:
a drive wheel; and
a second rotary electric machine connected to the drive wheel, wherein
the electronic control unit is configured to make the drive wheel rotate by using power of the second rotary electric machine during execution of the regeneration cut control.

### Claim 4

A control method for a vehicle,
the vehicle including an internal combustion engine, a filter, a heater, and an electronic control unit,
the filter configured to collect particulate matter contained in exhaust gas of the internal combustion engine,
the heater configured to be able to heat up a vehicle cabin by using exhaust heat of the internal combustion engine, and
the electronic control unit configured to execute regeneration cut control and heating control,
the control method comprising:
executing, by the electronic control unit, the heating control when the heating control is requested; and
not executing, by the electronic control unit, the heating control but executing the regeneration cut control when the heating control is requested and the regeneration cut control is requested,
the regeneration cut control being a control for regenerating the filter by stopping a fuel supply to the internal combustion engine and supplying oxygen to the filter in a state where an output shaft of the internal combustion engine rotates, and the heating control being a control for bringing the internal combustion engine into a combustion state and heating by the heater using exhaust heat of the internal combustion engine.
