DSRC on-vehicle device

Year	Description
1999	Invention patented by Masahiro Inoue on September 27th, 1999. Abstract: Since a conventional DSRC on-vehicle device does not include a device for informing a user of an abnormal power source voltage even if the power source voltage is abnormal, the user is not aware of the abnormal power source voltage and the DSRC on-vehicle device may not be correctly operated or may be damaged by heat or the like. DSRC on-vehicle device is equipped with an arithmetic processing device, a power supply device for receiving power supplied from a power source of a vehicle, a voltage regulation device for regulating a power source voltage to supply the power source voltage supplied through the power supply device to the arithmetic processing device, an abnormal voltage detection device for determining whether the power source voltage is set within a predetermined range, an abnormality signaling device for informing a user of an abnormality of the power source voltage supplied through the power supply device, and a signal processing device for driving the abnormality signaling device on the basis of an abnormal voltage signal transmitted from the abnormal voltage detection device.
