Abstract

A system for use with an automotive vehicle supported on front and rear pairs of road wheels to detect a drop in a tire air pressure for each of the road wheels. When the vehicle is detected as operating substantially in a steady straight line driving condition, the road wheel having a dropped tire air pressure is specified based on the angular speeds of rotation of the respective road wheels. This detection is made based on the angular road wheel speeds in view of changes in loads exerted in the respective road wheels caused by the tire air pressure drop.
