A vision-based approach to wheel camber angle and tyre Loaded Radius measurement
Sensors and Actuators A: Physical, 2010Co-Authors: Christophe Lamy, Michel BassetAbstract:The accurate determination of a vehicle's lateral behaviour is necessary in the domain of vehicle dynamics to improve vehicle safety. Its interaction with the road surface must be understood thoroughly, which requires the integration of a force model, representing the tyre-ground interface, into the global vehicle model. The validity of such a model directly depends on its nature and more particularly on the accurate determination of its inputs and outputs. This paper focuses on one input: the wheel camber angle. Studies in collaboration with a car maker have shown that a measurement error below 0.1◦ is necessary to identify the tyre model parameters from real data accurately. At the same time, measurement performance must be insensitive to the test conditions, and more particularly to the road surface (tyre-road grip). For these reasons, a novel vision-based method for direct camber determination has been developed and a measurement prototype has been designed. Its vision-based principle is mainly aimed at giving accurate measurement. Its precision is robust to the road's unevenness and the vehicle's velocity; the tyre Loaded Radius is determined at the same time. The novel method's feasibility and the measurement performance of the designed prototype have been studied from real vehicle-on-track measurements with a test car.

an improved magic formula swift tyre model that can handle inflation pressure changes
Vehicle System Dynamics, 2010Co-Authors: Ijm Igo Besselink, Ajc Antoine Schmeitz, Hans B PacejkaAbstract:This paper describes extensions to the widely used TNO MF-Tyre 5.2 Magic Formula tyre model. The Magic Formula itself has been adapted to cope with large camber angles and inflation pressure changes. In addition, the description of the rolling resistance has been improved. Modelling of the tyre dynamics has been changed to allow a seamless and consistent switch from simple first-order relaxation behaviour to rigid ring dynamics. Finally, the effect of inflation pressure on the Loaded Radius and the tyre enveloping properties is discussed and some results are given to illustrate the capabilities of the model.
