Abstract

For increased safety and economic reasons in the world, motor vehicle manufacturers are beginning to install TPMSs (Tire Pressure Monitoring Systems). There are two types of TPMSs in the market; one is a direct TPMS using pressure sensor; the other is an indirect TPMS using the wheel speed sensor signals from the antilock brake system (ABS). Most indirect TPMSs are unable to detect a 4-tire simultaneous deflation condition because indirect TPMSs are based on the principle that the 4-tire speed signals are compared with each other. However, the SRI Group (Sumitomo Rubber Industries, Ltd.) has developed an indirect TPMS which can detect a 4-tire simultaneous deflation based on a newly developed principle using wheel speed signals from the ABS.
