LOWERED TIRE AIR PRESSURE ALARMING METHOD AND APPARATUS, AND COMPUTER READABLE RECORDING MEDIUM RECORED LOWERED TIRE AIR PRESSURE ALARMING PROGRAM

摘要

slip rate (slip ratio) and can reduce the number of operations for obtaining a primary regression line of the acceleration and, also has the purpose of providing a way to road surface condition is not constant even when the detecting accuracy can be increased internal pressure of the tire decreases. A step of detecting the rotational information obtained from tires attached to a vehicle, the wheel speed from the rotational information of each tire, vehicle acceleration, calculating a slip rate of each of the front and rear step, a step of accumulating the vehicle acceleration and the slip rate of the front and rear wheels , by comparing the reference value of the primary regression coefficient is calculated by the pre-process in step, when the reference internal pressure of the primary regression coefficient of the tire to obtain the mutual primary regression coefficient of the vehicle acceleration and the slip rate of the front and rear wheels, decreased tire pressure alarm which comprises the step of determining whether a tire that is under reduced pressure.
