Pneumatic Tyre Aquaplaning: an Experimental Investigation on Manifestations and Influences of Appearance

Abstract

Aquaplaning at wet road conditions and high speeds can be a source of dangerous driving situations and accidents. The proper understanding of characteristic effects can be crucial in early aquaplaning detection and accident avoidance, essential for driver and driver assistance systems and trajectory planning for self-driving cars. Four test vehicles were equipped with a basic measurement system, and measurements were performed to evaluate characteristics of aquaplaning, such as wheel spin-up and wheel spin-down, change of rolling resistance, tyre slip slope, and tie rod force. Driveline configuration, type, wear and inflation pressure of the tyre(s), water level height next to chosen speed and performed manoeuvre significantly affect vehicle behaviour and thus the possibility to detect aquaplaning conditions. The results and main findings may allow and help establish corresponding methods to early detect aquaplaning and dangerous driving conditions.
