Abstract:
A DSRC on-vehicle device used in short range communication for Intelligent Transport Systems, comprising:arithmetic processing means for processing communications traffic between the DSRC on-vehicle device and an on-road unit;power supply means for receiving power supplied from a power source of a vehicle;voltage regulation means for regulating a power source voltage to supply the power source voltage supplied through the power supply means to the arithmetic processing means;abnormal voltage detection means for detecting the power source voltage supplied through the power supply means to determine whether the power source voltage is set within a predetermined range;abnormality signaling means for informing a user that the power source voltage supplied through the power supply means is abnormal; andsignal processing means for driving the abnormality signaling means on the basis of an abnormal voltage signal transmitted from the abnormal voltage detection means.
