HYBRID VEHICLE AND CONTROL METHOD OF HYBRID VEHICLE

摘要

A hybrid vehicle (100) runs, switching between an HV mode for running with an engine (4) operated, and an EV mode for running by the driving power of a motor generator (MG2) with the engine (4) stopped. An ECU (50) accumulates the running distance in the HV mode up to a predetermined value X1, and determines that a fuel sender gauge (41) is in malfunction when the difference between the amount of change of the fuel sender gauge (41) until the running distance in the HV mode is accumulated up to the predetermined value amount X and the estimation value of the fuel consumption amount exceeds a criterion value Y1.
