Patent ID: 7642902

Claim:
A vehicle abnormality detecting device comprising: an abnormality detecting unit for detecting abnormality on the basis of a state of current flow to a state detecting unit, the state of current flow including a normal current, an abnormal current and an adjusted current; and a power supply control unit for switching a state of a power supply to the state detecting unit when the abnormality is detected by the abnormality detecting unit, wherein: the abnormality detecting unit detects abnormality in an installation state of a device in a vehicle on the basis of the state of current flow to the state detecting unit in which the abnormal current is supplied when the installation state of the device in the vehicle chances from a normal state to an abnormal state; and the power supply control unit switches, after the abnormality is detected, a state of the power supply for the state detecting unit to a state (1) supplying the adjusted current smaller than the abnormal current or (2) controlling the adjusted current to be cut off, so that consumption of power is suppressed.
