Abstract
Method of indicating effective circumferences of rolling vehicle wheels
Highlights
Research on rolling radius on various road surfaces has been the subject of discussions and scientific studies for many years [10, 13, 15, 17, 18, 21, 22, 23]
Of considerable importance is the influence of a vehicle's wheel rolling radius value on the functioning of active safety systems, which collect information on the rotational speeds of individual wheels
With the presented method for testing effective wheel rolling circumferences, it is possible to elaborate the regression model, allowing for high accuracy determination of EOT value, and of the dynamic radii of vehicle's wheels based on the vertical load of the drive axles and the tyre pressure
Summary
Research on rolling radius on various road surfaces has been the subject of discussions and scientific studies for many years [10, 13, 15, 17, 18, 21, 22, 23]. Due to the importance of change in the value of a vehicle's wheel rolling radius in varied conditions of vertical wheel load, GPS instruments are often used for registering linear speed [4, 8, 15]. Of considerable importance is the influence of a vehicle's wheel rolling radius value on the functioning of active safety systems, which collect information on the rotational speeds of individual wheels. In the case of simple calculations, dependencies estimating wheel rolling radius value based on the free radius value are used. Such an approach is burdened with considerable error [1]. The drawback of the approach presented in the paper is the assumption that rolling radius is a constant value, which may be determined in quasi-static conditions, as done by Kiss (2003), or that a large amount of empirical
