Abstract
A reliable and precise measurement of tire tread wear, by using wide-band (UWB) pulses and analyzing the signature obtained by reflection of these pulses from the tread, in order to deduce its state of wear therefrom. The tire wear monitoring device (100) includes a control unit (110) for signal control and data processing, this control unit (110) being coupled to a generator of ultra wide band or UWB signals (120), which is itself coupled to an antenna for incident UWB pulse transmission (140), and an antenna for receiving the UWB pulses (150) reflected from at least one interface of the tire tread, the reception antenna (150) being coupled to a pulse signal receiver (180) which is itself coupled to the control unit (110).
