Detection of incorrect functioning of a motor vehicle tire by estimating the tire internal temperature based on operating conditions and comparing the estimate with a measured value, with significant difference indicating a fault |
摘要 |
Method for estimating the internal temperature of a tire in which a calibration step is carried out comprising a series of measurements of internal temperature using an internal temperature sensor for varying external temperatures, loading and tire pressures. A function is then deduced linking internal tire temperature to external tire temperature. Independent claims are made for a device for detecting abnormal function of a motor vehicle tire and a method for the same whereby: during normal running of a vehicle the external temperature is measured and used to estimate tire internal temperature. If there is a significant difference between measured and estimated internal temperatures incorrect tire functioning is indicated.
