Tire air pressure reduction detecting apparatus

摘要

The present invention provides a tire air pressure reduction detecting apparatus arranged such that both an ABS processing and an air pressure reduction judgment processing can be executed with a single microcomputer. A vacant period of time tn for timing waiting is prepared in each ABS cycle. Utilizing such vacant periods of time tn, an air pressure reduction Judgment processing is dispersively executed in a time-division manner in a plurality of such vacant periods of time tn (FIG. 4).
