Title: Judgment of low tire inflation pressure and device therefor
Inventor: IIDA AKIKO
IPC: B60C23/00
Filed: 1993-12-28
Abstract: PURPOSE:To realize the judgment having high reliability for the reduction of the tire inflation pressure by excluding the revolution angle speed calculated in the cycle immediately before or after the judgment cycle, for the judgment of the reduction of the tire inflation pressure. When it is judged that the traveling state is hot suitable for the judgment of the reduction of the tire inflation pressure. CONSTITUTION:The revolution angle speed of each tire is calculated in each prescribed sampling cycle by the CPU 2b of a control unit 2 on the basis of the wheel speed pulse detected by a wheel speed sensor 1 installed for each wheel of a four-wheel vehicle, and the reduction of the tire inflation pressure is judged on the basis of each revolution angle speed. In this case, if the car speed V, turning radius R, and the lateral and the longitudinal speed G and A satisfy all the following conditions; V>=10km/h, ¦R¦>=30m, ¦lateral acceleration G¦<=0.4G, ¦A¦<=0.1G, it is judged that the traveling state suitable for the pneumatic pressure reduction judgment is generated, while if the judgment is 'NO', the revolution speed calculated immediately before or after the judgment cycle is not adopted for the judgment of the reduction of the tire inflation pressure, and the erroneous judgment is prevented beforehand.
