Claim:
1. A hybrid vehicle comprising: an internal combustion engine; a rotating electric machine; a fuel tank storing fuel supplied to said internal combustion engine; a detector for detecting an amount of fuel in said fuel tank; a malfunction determination unit determining a malfunction in said detector based on a detection value by said detector; and a running mode control unit controlling switching between a first running mode for running with said internal combustion engine operating and a second running mode for running by driving power of said rotating electric machine with said internal combustion engine stopped, said malfunction determination unit determining in said first running mode that said detector is in malfunction when a predetermined first condition is met, and determining in said second running mode that said detector is in malfunction when a predetermined second condition differing from said first condition is met, said first condition being met when a difference between a fuel consumption amount estimated to be consumed during running in said first running mode and an amount of change in said detection value during running in said first running mode exceeds a predetermined value, and said second condition being met when said detection value by said detector exceeds a predetermined range during running in said second running mode, wherein said malfunction determination unit determines whether or not said first condition is met when a first state amount indicating an amount of running in said first running mode reaches a first predetermined amount, and determines whether or not said second condition is met when a second state amount indicating an amount of running in said second running mode reaches a second predetermined amount, and said second predetermined amount is smaller than said first predetermined amount.
