Abstract
A tire wear detection apparatus for a vehicle includes a tire side apparatus and a vehicle body side system. In response to a wet road surface being detected, from a vibration waveform of a tire indicated by a detection signal according to a magnitude of a vibration of the tire, the tire side apparatus is configured to (i) acquire a peak level value of a vibration level at a stepping time at which an apparatus corresponding position in the tire corresponding to an arranged position of the tire side apparatus starts to contact the road surface, and/or (ii) calculate a level value of the vibration level in a post-kicking range after the apparatus corresponding position kicks to separate from the road surface, so as to generate a wear data indicating a wear state of the tire.
