<P>PROBLEM TO BE SOLVED: To provide a hybrid vehicle appropriately starting an internal combustion engine under a cold condition and suppressing exhaust emission by suppressing the amount of fuel injected from a fuel injection valve. <P>SOLUTION: This hybrid vehicle 1 including the engine 11 driven by burning fuel and an electric motor driven by supplying electric power includes: an A/F sensor 88 detecting the air-fuel ratio of the engine 11; a heater 89 preheating the A/F sensor 88; and an air-fuel ratio control section 103 performing air-fuel ratio feedback control controlling the air-fuel ratio in order to approach a target air-fuel ratio based on a detection result detected by the A/F sensor 88. The heater 89 preheats the A/F sensor 88 by the time the engine 11 is started under the cold condition, and the air-fuel ratio control section 103 performs the air-fuel ratio feedback control immediately after the engine 11 is started under the cold condition. <P>COPYRIGHT: (C)2009,JPO&INPIT |
