主动安全系统将受益于关于轮胎力的准确信息。一个特殊的传感器模块已开发用于研究目的，研究实时轮胎力估计从轮胎胎体位移。可以在垂直、横向和纵向方向上测量力。该传感器测量轮胎胎体相对于轮辋的运动，并将数据无线传输到底盘。原始数据进行分析，轮胎力的信息是在CAN总线上。该传感器在轮胎试验台上进行了标定，给出了试验场测量结果。与车辆加速度相比，横向和纵向力的估计是准确的，但在重制动操作期间，垂直力难以估计。
Active safety systems would benefit from accurate information on tyre forces. A special sensor module has been developed for research purposes to study real-time tyre force estimation from tyre carcass displacements. The forces can be measured in vertical, lateral and longitudinal directions. The sensor measures tyre carcass movement with respect to the rim and transmits the data wirelessly to the chassis. The raw data is analysed and tyre force information is available on a CAN-bus. The sensor is calibrated in a tyre test rig and proving ground measurement results are presented. The lateral and longitudinal force estimates are accurate when compared with the vehicle accelerations, but the vertical force is difficult to estimate during heavy braking manoeuvres.
