Claim 0:
1. 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, and when the UWB modules are driven, two of the multiple UWB modules are driven, and when a signal strength is measured, signal strength of other modules received by one of the two driven modules is measured;
a ranging unit configured to perform ranging between the driven UWB modules;
a storage unit configured to store position information of the UWB modules; and
an appropriateness determination unit configured to compare a measured distance value obtained through the ranging of the ranging unit to a reference distance value based on the position information stored in the storage unit, determine that the measured distance value is appropriate when the measured distance value is the same as the reference distance value, and determine that the measured distance value is not appropriate when the measured distance value is not the same as the reference distance value.
