In the coming decade, proven aerospace technology will replace many of the hydrauic and mechanical systems of automobiles today. By-wire technology will control steering, gear change, acceleration, and braking. Instead of using traditional mechanical and hydraulic interfaces, the driver communicates his or her intentions to the vehicle's major operating systems electronically. Smart electro-mechanical actuating units (SEMAUs) with integrated sensors and measurement systems do the rest. Each SEMAU translates rotational motion into linear motion via a brushless motor/ball screw assembly. The motor features an external stator and internal rotor mechanically connected to the ball screw. A micoprocessor on the SEMAU allows digital closed loop control and supports application-specific logic. This article describes a new concept car: Filo, in which shift-by-wire, steer-by-wire and brake-by-wire systems are realized. The drive-by-wire systems are very flexible because each smart electro-mechanical actuating unit communicates with the vehicle control system. The Filo concept car demonstrates the enormous potential of drive-by-wire.
