Investigation of brake wear particles. - In: Readout, (2012), 39, S. 34-38

Over the last years, brake dust has become a topic in different fields. The first research to brake dust after the abolishment of asbestos was done to understand the staining of the wheel. Since then, several attempts were made to understand the synthesis, composition and distribution of brake dust because of the growing awareness of environmental and health effects, for example with antimony and copper in the brake pads. The published measurements for the number and size of brake particles vary widely [1-5]. This is mainly because of the complex and susceptible characteristics of a brake system and the limited resolution of many measurement systems. With every change in temperature, braking speed, braking pressure, pad formulation, brake type and history of the friction partner, differences in the properties of brake dust particles will be recognizable. One approach to measure the size of the particles is to analyze a sample of collected brake dust in a scanning electron microscope. The handicap of this method is the characteristic of the debris to agglomerate and to deposit dependent on the particle size. A precise analysis of airborne particulate matter requires a more complex methodology which is known from the combustion engine particle measurement. HORIBA offers equipment to detect the particle size from ˜2nm up to 600nm, for example the Mexa-2100SPCS with a DMA 3081 classifier and a CPC 3776.

Torque vectoring for improving the mobility of all-terrain electric vehicles. - In: Proceedings of the 12th European Regional Conference of the ISTVS, ISBN 978-0-9838742-1-8, 2012, Session 7, insges. 8 S.

Torque vectoring (TV) is one of the most promising technologies in vehicle dynamics control as it has the potential to provide distinctive benefits for mobility and agility of all-wheel drive ground vehicles. Especially in all-terrain driving, TV control can support both vehicle stability and driving efficiency. Within this context, the paper presents the state-of-the-art in TV control and introduces a new methodological approach for the development of TV control systems for all-terrain electric ground vehicles. This approach implements individually controlled electric powertrains to tune the vehicle dynamic characteristics in steady-state and transient conditions. The presented research is carried out within the European Union (EU) funded Seventh Framework Programme (FP7) project E-VECTOORC "Electric-Vehicle Control of Individual Wheel Torque for On- and Off-Road Conditions".
