Classification: CPC G  B | IPC B  G

Claim 6:
7. A position detection device for a vehicle ultra-wideband (UWB) module, the position detection device comprising:
a diagnosis device interface configured to receive a diagnosis command from a diagnosis device and output a diagnosis result to the diagnosis device;
a UWB module driving unit configured to drive multiple UWB modules when diagnosis is started;
a signal strength measurement unit configured to measure signal strength of other modules received by the driven UWB module, and when the UWB modules are driven, two of the multiple UWB modules are driven, and when the signal strength is measured, signal strength of other modules received by one of the two driven modules is measured;
a storage unit configured to store signal strength of each UWB module; and
an appropriateness determination unit configured to compare measured signal strength obtained by the signal strength measurement unit to the stored signal strength in the storage unit, determine that the measured signal strength is appropriate when the measured signal strength and the stored signal strength are the same, and determine that the measured signal strength is not appropriate when the measured signal strength and the stored signal strength are not the same.
