SpeedE is a research and development platform in the form of a sporty electric vehicle designed by the institute for motor vehicles (ika, Institut für Kraftfahrzeuge) of the RWTH Aachen University. Besides a variety of innovative systems, a steer-by-wire system for lateral guidance of the vehicle is an important research focus of the SpeedE. For this steering system, PUMA ECUs, which are networked via FlexRay with the vehicle, control the electric drive units for setting the desired wheel steering angle.
