Detecting tire pressure loss in vehicles while traveling, involves modifying detection method if wheels have rolling characteristics that differ from each other owing to tire quality differences

摘要

The method involves evaluating wheels angular speeds measured by sensors or information representing angular speeds based on time intervals. It involves forming speed interval reference values, setting upper and lower thresholds (11,12) for tire pressure detection using the reference values and modifying the pressure loss detection method if the wheels have rolling characteristics that differ from each other as a result of different tire quality.
