Smart Algorithm for a Tire Pneumatic Pressure Monitor Embedded in ABS Program 980237
This paper describes methods to attain a low cost tire pneumatic pressure monitor. We already established two kinds of algorithms for indirect detection of under-inflated tires without requiring any air pressure sensors. One method is to use a disturbance observer and the least mean square method. The other method is to compare the loaded radii of the tires. We have developed an algorithm that reduces the number of calculations needed, while maintaining a relatively small program size, and realized a tire pneumatic pressure monitor that does not require any hardware cost, by incorporating it into the program for the antilock brake system (ABS).
