Evaluation of Velocity and Curvature Dependence for Roadgrip Measured by Low Lateral Slip
(English)In: International Journal of Vehicle Systems, Modeling and Testing, ISSN 1745-6444Article in journal (Refereed) Accepted
Roadgrip is a important parameter for vehicle testing and road maintenance. Therefore an evaluation of the velocity and curvature effects on roadgrip measurement was performed on asphalt roads and on two ice tracks using the continuous roadgrip apparatus RT3 Curve. The aim was to find suitable driving patterns for measurements on public roads and test tracks to ensure the repeatability of roadgrip measurements. During the evaluation it was concluded that in order to achieve a reliable roadgrip value, regardless of road conditions, the radius of curvature should not be less than 20 m. The velocity dependency of the RT3 Curve is different for the two road conditions, with the measurements on ice being much more sensitive to velocity changes than the measurements on the dry asphalt.
