Claim 12:
13. A position detection method for a vehicle ultra-wideband (UWB) module, the position detection method comprising:
driving multiple UWB modules when diagnosis is started;
performing at least one of ranging between the driven UWB modules and measurement of signal strength of other modules received from one of the driven multiple UWB modules, 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;
comparing a measured distance value obtained through the ranging to a reference distance value based on position information of the UWB modules when the ranging is performed; and
determining that the measured distance value is appropriate when the measured distance value is the same as the reference distance value, and determining that the measured distance value is not appropriate when the measured distance value is not the same as the reference distance value or comparing measured signal strength to reference signal strength of each UWB module when the signal strength measurement is performed, determining that the measured signal strength is appropriate when the measured signal strength and the reference signal strength are the same, and determining that the measured signal strength is not appropriate when the measured signal strength and the reference signal strength are not the same.
