1. A hybrid vehicle comprising:
- an electric motor configured to generate a running driving force;
an internal combustion engine;
a heating system configured to heat a passenger compartment, the heating system including a first heating apparatus that is configured to use the internal combustion engine under operation as a heat source, and a second heating apparatus that is configured not to use the internal combustion engine as a heat source; and
an electronic control unit configured to;
(a) detect deterioration of fuel to be supplied to the internal combustion engine, and(b) control the electric motor, the internal combustion engine, and the heating system, such that, when the electronic control unit detects the deterioration of the fuel, the electronic control unit controls the heating system and the internal combustion engine so as to give priority to heating by the first heating apparatus over heating by the second heating apparatus.

Abstract
An ECU determines whether or not fuel in a fuel tank deteriorates. A heating system is configured to be able to perform heating (engine heating) using heat of an engine which heating uses the engine under operation as a heat source, and heating (heat-pump heating) using a heat pump cycle without using the engine as a heat source. When it is determined that the fuel in the fuel tank deteriorates, the ECU controls the heating system and the engine so as to give priority to the engine heating over the heat-pump heating.
