MEASURING METHOD AND MEASURING APPARATUS
First Claim
1. A measuring method, comprising the steps of:
- detecting a charge potential distributed over a vehicle body or a tire resulting from contact, separation, and friction between a tire and a road surface; and
monitoring an amplitude of the charge potential detected in the step of detecting.

Abstract
A charge potential distributed over a vehicle body resulting from the contact, separation, and friction between a tire and a road surface is detected by a detecting unit provided with a sensing electrode that is disposed on the external surface of the vehicle body, a reference electrode that is disposed apart from the external surface of the vehicle body with a space therebetween, and a sensor amplifier that senses a potential between the sensing electrode and the reference electrode as a signal and amplifies the signal. And the amplitude of the charge potential detected by the detecting unit is monitored by a data processing unit, thereby making it possible to accurately identify not only the state of the road surface but also an internal pressure state of the tire, a wear state of the tire, and the like during vehicular travel.
