主动安全系统将受益于轮胎力和摩擦潜力信息。目前正在研究不同的传感器概念，其中包括由欧盟资助的阿波罗项目开发的基于光学位置探测的轮胎传感器。传感器可以测量轮胎胎体相对于轮辋的偏转。胎体挠度可用于计算轮胎力，并可用于估计摩擦潜力。示出了传感器信号的波形。垂直和横向力的估计，提出了不可避免的补偿部分。将轮胎传感器测量值与测量车辆结果进行比较，并获得良好的相关性。持续的活动涉及摩擦潜力的估计和滑水的检测。
Active safety systems would benefit from tyre force and friction potential information. Different sensor concepts, including, among others, the EU-funded Apollo-project developed tyre sensor based on optical position detection, are being studied. The sensor can measure tyre carcass deflections with respect to the rim. The carcass deflections can be used to calculate tyre forces and they may be exploited in the estimation of friction potential. The waveforms of the sensor signal are illustrated. The vertical and lateral force estimations are presented with unavoidable compensation parts. The tyre sensor measurements were compared to the measurement-vehicle results and good correlations achieved. Continuing activities are concerned with the estimation of friction potential and the detection of aquaplaning.
