Abstract
Sensing devices for intelligent tire that can measure the friction coefficient of a road surface are actively researched so as to improve the performance of vehicle motion control systems such as ABS (anti-lock braking system). Most of previous proposed devices, however, need complicated systems and have not been put to practical use. This study proposed a simple tactile sensor for an intelligent tire and established a method determining the value of the vertical load and frictional force that acting on the tire from the sensing results. Furthermore, the prototype tactile sensor was fabricated and its availability was confirmed.
