Tire inflation state detecting method for motor vehicle, involves measuring angular speeds of wheels, calculating comparison criteria that compare speeds of wheels, respectively, and analyzing criteria to detect inflation state of tire

摘要

The method involves measuring angular speeds of motorized front wheels and follower rear wheels of a motor vehicle. A comparison criterion comparing measured speeds of one front wheel and one rear wheel on a side of the vehicle with measured speeds of another front wheel and another rear wheel on another side of the vehicle is calculated. A comparison criterion comparing measured speeds of the front wheels on a front axle of the vehicle with measured speeds of the rear wheels on a rear axle of the vehicle is calculated. The criteria are analyzed for detecting an inflation state of a tire. An independent claim is also included for a system for detecting an inflation state of a tire of a front or rear wheel of a motor vehicle.
