Optical position detection sensor to measure tyre carcass deflections in aquaplaning

Information about the available friction of individual tyres is crucial for the operation of different Advanced Driver Assistance (ADAS) systems, such as collision mitigation and Adaptive Cruise Control (ACC). The information about aquaplaning is especially useful because aquaplaning severely hampers tyre-road interaction. In addition, validation tools are needed for complex physical tyre models, which are common development and research tools in the tyre industry. The optical tyre sensor is capable of accurately measuring the deformations in the inner ring of the tyre. Partial and full aquaplaning can be detected using the sensor. It also provides a research tool for understanding the phenomenon itself.
