摘要：A charge potential distributed over a vehicle body (2A) resulting from thecontact, separation, and friction between a tire (2B) and a road surface (3) is detected by adetecting unit (10) provided with a sensing electrode (11) that is disposed on the externalsurface of the vehicle body (2A), a reference electrode (12) that is disposed apart fromthe external surface of the vehicle body (2A) with a space therebetween, and a sensoramplifier (13) that senses a potential between the sensing electrode (11) and thereference electrode (13) as a signal and amplifies the signal. And the amplitude of thecharge potential detected by the detecting unit (10) is monitored by a data processingunit (20), thereby making it possible to accurately identify not only the state of the roadsurface but also an internal pressure state of the tire, a wear state of the tire, and the likeduring vehicular travel.
