Abnormality determination apparatus for vehicle
First Claim
1. An abnormality determination apparatus for a vehicle comprising:
- a heat flux sensor having a thermoplastic resin made insulating substrate to which a plurality of first and second via holes penetrating in a thickness direction thereof are formed, first and second interlayer connection members composed of different metals from each other that are embedded in the first and the second via holes, the first and the second interlayer connection members being connected in series alternately; and
a control unit that performs abnormality determination of a heating element disposed in a vehicle;
wherein,at least one of the metal forming the first and the second interlayer connection member is a sintered alloy that is solid-phase sintered in a state where a plurality of metal atoms maintaining a crystal structure of the metal atoms;
the heat flux sensor is provided to the heating element and outputs a sensor signal corresponding to heat flux between the heating element and an outside air; and
the control unit determines based on the sensor signal that there is abnormality in the heating element when the heat flux between the heating element and the outside air is out of a predetermined range.

Abstract
There is provided a heat flux sensor with first and second interlayer connection members composed of different metals from each other of which metal atoms maintain a predetermined crystal structure embedded in first and second via holes of a thermoplastic resin made insulating substrate, the first and the second interlayer connection members are connected in series alternately, and a control unit that performs abnormality determination of a heating element disposed in a vehicle. The heat flux sensor is provided to the heating element and outputs a sensor signal corresponding to heat flux between the heating element and an outside air, and the control unit determines based on the sensor signal that there is abnormality in the heating element when the heat flux between the heating element and the outside air is out of a predetermined range.
