Abstract

A control apparatus for a hybrid vehicle includes an engine for traveling, a motor for traveling, and a battery exchanging electric power with the motor. the control apparatus including: a heater is configured to perform heating inside a cabin of the hybrid vehicle by using the engine or an electric heat source as a heat source; and a controller is configured to operate the engine intermittently, the controller is configured to select the heat source for the heater, the controller is configured to determine whether or not a fuel for the engine is degraded when the engine is stopped, and the controller is configured to start the engine and select the engine as the heat source when the controller determines that the fuel is degraded.

Claims

1. A control apparatus for a hybrid vehicle including an engine for traveling, a motor for traveling, and a battery exchanging electric power with the motor,

the control apparatus comprising:

a heater configured to perform heating inside a cabin of the hybrid vehicle by using the engine or an electric heat source as a heat source; and

a controller configured to operate the engine intermittently, the controller configured to select the heat source for the heater, the controller being configured to determine whether or not a fuel for the engine is degraded when the engine is stopped, and the controller being configured to start the engine and select the engine as the heat source when the controller determines that the fuel is degraded.

2. The control apparatus for a hybrid vehicle according to claim 1, wherein

the controller is configured to extend, when the controller determines that the fuel is degraded and the heater heats the cabin, a warm-up time of the engine longer in comparison with a case when the controller determines that the fuel is not degraded and the heater heats the cabin.

3. The control apparatus for a hybrid vehicle according to claim 1, wherein

the controller is configured to increase, when the controller determines that the fuel is degraded and the heater heats the cabin, a revolution speed of the engine during warm-up higher in comparison with a case when the controller determines that the fuel is not degraded and the heater heats the cabin.

4. The control apparatus for a hybrid vehicle according to claim 1, wherein:

the controller is configured to extend, when the controller determines that the fuel is degraded and the heater heats the cabin, a warm-up time of the engine longer in comparison with a case when the controller determines that the fuel is not degraded and the heater heats the cabin, and the controller is configured to increase, when the controller determines that the fuel is degraded and the heater heats the cabin, a revolution speed of the engine during warm-up higher in comparison with a case when the controller determines that the fuel is not degraded and the heater heats the cabin.
