Vehicle fault determination device
First Claim
1. A vehicle fault determination device comprising:
- a relay connected to a power source;
a vehicle configuration circuit supplied with power from the power source via the relay; and
a control section adapted to determine whether the relay is faulty while controlling the relay and the vehicle configuration circuit;
wherein the control section includes;
a first port adapted to output a control signal to a coil portion of the relay; and
a second port connected to a contact portion of the relay via the vehicle configuration circuit; and
the second port serves as an input port when the fault determination is made and as an operation port when the vehicle configuration circuit is controlled;
wherein the control section outputs a given test signal to the first port during the fault determination; and
the control section determines whether the relay is faulty based on the signal input to the second port.

Abstract
A vehicle fault determination device includes a relay, a vehicle configuration circuit, and a control section. The relay is connected to a power source. The vehicle configuration circuit is supplied with power from the power source via the relay. The control section determines whether the relay is faulty while controlling the relay and the vehicle configuration circuit. The control section includes first and second ports. The first port outputs a control signal to a coil portion of the relay. The second port is connected to a contact portion of the relay via the vehicle configuration circuit. The second port serves as an input port when the fault determination is made and as an operation port when the vehicle configuration circuit is controlled. Thus, the number of parts is keep to a minimum to increase the number of dedicated ports for determining whether the relay is faulty.
