摘要
针对越野汽车轮胎充气过程胎压动态复杂变化情况,提出一种轮胎充气过程胎压实时预估方法。主要由数据采集与预处理模块、预标定轮胎气阻模块及轮胎胎压预估模块组成;根据测压工况轮胎胎压值估算出轮胎气阻值;在此基础上,轮胎胎压预估模块利用气动原理循环预估轮胎胎压;并通过轮胎中央充放气系统平台进行验证。结果表明:该算法预估的均方根误差不超过0.0843 MPa,极大提高了胎压预估的精度。
In view of the complex dynamic changes of tire pressure during the inflation process of off-road vehicle tires,a real-time prediction method of tire pressure during the inflation process was proposed.The method mainly comprise a data acquisition and preprocessing module,a pre-calibration tire air resistance module and a tire pressure estimation module,wherein a tire air resistance value is estimate according to a tire pressure value of a pressure measuring working condition;and on that basis,the tire pressure estimation module circularly estimates the tire pressure by using a pneumatic principle.Through the verification of the tire central inflation and deflation system platform,the results show that the root mean square error of the algorithm is not more than 0.0843 MPa,which greatly improves the accuracy of tire pressure prediction.
