HYBRID VEHICLE AND CONTROL METHOD OF HYBRID VEHICLE

摘要

An ECU determines in an HV mode that a fuel sender gauge is in malfunction when a first condition is met, and determines in an EV mode that the fuel sender gauge is in malfunction when a second condition differing from the first condition is met. The first condition is met when the difference between an estimated value of the fuel consumption amount and an amount of change in the detection value by the fuel sender gauge is greater than a predetermined value Z. The second condition is met when the detection value changes exceeding a predetermined range X.

主权项

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 operated 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 a detection value by said detector changes exceeding a predetermined range during running in said second running mode.
