A system (100) and method (200) for estimating at least a load acting on a tire (122) mounted on a vehicle is provided. In one embodiment, a sensor (118) mounted on a tire generates output signals corresponding to at least a tire inflation pressure and a ground print length. A linear model between the load of the tire and the ground print length and derived model coefficients as a function of at least the sensed tire inflation pressure are retrievably stored (214, 224). A local controller (102), remote server (130) or other computing device (140) is linked to sensors and data storage means (106, 134) mounted on the tire, and is further configured to estimate a load (230) acting on the tire from a linear model based on at least a ground print length, a sensed tire inflation pressure, and derived model coefficients (222), and generate an output signal corresponding to the estimated load (240) for display (242, 244), wear detection (246), traction detection (248), or other control functions.
提供了用于估计作用在安装在车辆上的轮胎(122)上的至少负载的系统(100)和方法(200)。在一个实施方案中,安装在轮胎上的传感器(118)生成对应于至少轮胎充气压力和接地印痕长度的输出信号。可检索地存储(214,224)轮胎的负载和接地印痕长度之间的线性模型,以及作为至少感测的轮胎充气压力的函数的导出的模型系数。本地控制器(102)、远程服务器(130)或其他计算设备(140)链接到安装在轮胎上的传感器和数据存储装置(106,134),并且还被配置为基于至少接地印痕长度、感测的轮胎充气压力和导出的模型系数(222)从线性模型中估计作用在轮胎上的负载(230),并且生成对应于估计负载(240)的输出信号用于显示(242,244)、磨损检测(246)、牵引力检测(248)或其他控制功能。
