Publication number: 20190202499Abstract: A steering control system for a commercial vehicle having braking and steering systems. The braking system brakes dissymetrically side wheels of the vehicle. The steering system steers the vehicle based on a steering signal. The steering control system includes selection and control modules. The selection module switches between first and second steering modes. The first mode indicates steering of the vehicle by turning vehicle wheels. The second mode indicates steering of the vehicle by generating a braking signal for at least one wheel providing a yaw moment applied to the vehicle. The control module generates the first signal indicating a steering demand in the first mode and a second signal indicating a steering demand in the second mode. The control module provides the first signal to the steering system and the second signal to the braking system to brake the vehicle dissymetrically to steer the vehicle with the yaw moment.Type: ApplicationFiled: September 8, 2017Publication date: July 4, 2019Inventors: Kornel Straub, Markus Klein, Levente Balogh, Jonas Leibbrand, Tamas Rozsa

Publication number: 20190202503Abstract: Various embodiments of an airfoil and machines with airfoils are disclosed. The airfoils include a thicker leading airfoil portion and a thinner trailing airfoil portion. In one embodiment, the leading airfoil portion is formed by bending a body of the airfoil back toward itself. In another embodiment, the leading airfoil portion has a solid geometry and includes two elliptic surfaces. To prevent detachment of airflow, the leading airfoil portion includes at least two arc portions or surfaces that act to direct the airflow down to the trailing airfoil portion in a manner that stabilizes vortexes that may form in the region of changing thickness.Type: ApplicationFiled: May 2, 2018Publication date: July 4, 2019Inventors: Michael Suk, David A. Shoffler

Publication number: 20190202505Abstract: There is provided an active drag-reduction system having first 22 and second 24 fluid outlets located on a vehicle 10 adjacent to a low pressure (drag) region 12, wherein fluid ejected from the second fluid outlet 24 is at a higher pressure/ejection velocity than from the first fluid outlet 22. Turbulent and/or low pressure regions adjacent to vehicles are not uniform, but rather have a varying intensity. For instance, the centre of a region may have a lower pressure and/or more turbulent nature than the periphery of the region. The system may inject relatively higher pressure air (or relatively higher speed air) into the relatively lower pressure/more turbulent part of the low pressure/turbulent region, and relatively lower pressure air (or relatively lower speed air) into the relatively higher pressure/less turbulent part of the low pressure/turbulent region, compared to each other.Type: ApplicationFiled: March 5, 2019Publication date: July 4, 2019Inventors: Osama Elogab, Hatem Elogab

Publication number: 20190202506Abstract: A transporter for transporting a load over a surface. The transporter includes a support platform for supporting the load. The support platform is characterized by a fore-aft axis, a lateral axis, and an orientation with respect to the surface, the orientation referred to as an attitude. At least one ground-contacting element is flexibly coupled to the support platform in such a manner that the attitude of the support platform is capable of variation. One or more ground-contacting elements are driven by a motorized drive arrangement. A sensor module generates a signal characterizing the attitude of the support platform. Based on the attitude, a controller commands the motorized drive arrangement.Type: ApplicationFiled: March 8, 2019Publication date: July 4, 2019Inventors: Dean Kamen, Richard Kurt Heinzmann, Robert R. Ambrogi
