Real-time estimation of aquaplaning with an optical tyre sensor

Abstract

Future active safety systems will require more accurate information about the state of a vehicle and the operating conditions of an individual tyre. Aquaplaning is a dangerous situation in which the contact between the tyre and the road is partially or completely lost. In this paper, the movements of the inner liner of the tyre during aquaplaning are measured optically and exploited to estimate aquaplaning. The results from proving-ground tests are shown and compared with those of the conventional approach of estimating aquaplaning from wheel speeds. The proposed method performs reliably in real time and can detect several different levels of aquaplaning. The results support the future development of production-capable tyre sensors. An optical tyre sensor also provides a research tool for attaining an in-depth understanding of the aquaplaning phenomenon.
