Drive-By-Wire Systems
The idea of ‘X-by-wire’, the control of a car’s vital functions like steering and breaks by electrical rather than mechanical links, it tantalizing to some and terrifying to other.
Aircraft may have been equipped with Fly-by-wire system for years, but do we really feel comfortable at the idea of computer sitting between ourselves and steering and breaks of our car?
What might, however, at first sound alarming actually has many benefits and whatever we as costumers may think, X-by-wire is already emerging fast. Electronic throttles, the Mercedes sensotronic break controls (SBC) and now BMW’s active front steering (ABS) in the new launches are all examples of drive-by-wire technologies.
- Mercedes-Benz’s cutting edge sensotronic break control technology, used in new SL, delivers more breaking movement in an emergency and helps stabilize skid early.
- Delphi’s X-by –wire is a family of advanced breaking, steering, throttle and suspension control system which function without conventional mechanical component.
- GM’s hydrogen-power X-by-wire concept uses electrical signals instead of mechanical linkages or hydraulics to operate the motor, breaks and steering function.
Highly organized network of wired, sensors, controllers and actuators control the mechanical function of the vehicle’s steering, breaking, throttle and suspension control system.
