It's always nice to have an actual mechanical linkage to the steering and motion, if the electronics had issues it could just as well affect the BT link from the phone or controller. I'm not familiar enough with all makes and models out today and perhaps there are plenty of examples where wheels are already just "controllers".
- Phlarp 12y agoEssentially every new consumer grade car made today comes with power steering and electronically controlled or assisted "mechanical linkage". To say nothing of the recent high profile cases of large auto makers having faulty engine control software or mechanically unsound ignition systems.
- jessriedel 12y agoIt would almost certainly not be worth it for a robocar, but having an assisted mechanical linkage is valuable and very different from a pure electronic linkage (i.e. drive by wire). As emgee points out, drive by wire is essentially non-existent in consumer cars.
- emgeee 12y agoThe technical term you're looking for is "drive by wire" and it actually only came onto the market in the last year on the Infinity Q50.
- jonah 12y agoSure, Steer by wire is new. DBW generally refers to the connection between the accelerator pedal and the throttle. There, DBW has been the norm for many years.
- tantalor 12y agoSurely not the brake, though. Right? Right? Edit: http://en.wikipedia.org/wiki/Brake-by-wire http://en.wikipedia.org/wiki/Brake-by-wire
- mrtron 12y agoMechanical failure was always possible with brakes.
- robryk 12y agoEven if the pedal is physically connected to the brake cylinder ABS can do whatever it wishes to: ABS can apply and unapply brakes at any time, also asymetrically.
- paulyg 12y agoThis years F1 cars are brake by wire. It let's them control the kinetic energy recovery better.
- sudhirj 12y agoHaven't recent cars and even aeroplanes shifted entirely to drive by wire? The mechanical linkage is already gone for the most part.
