COMPUTER SYSTEMS DEVELOPED FOR AIRCRAFT ARE BEING ADAPTED FOR USE ON THE ROAD.

Susan Watts reports

CAR FIRM FORGES AHEAD WITH DRIVE-BY-WIRE PROTOTYPE

SAAB, the Swedish car maker, seems untouched by recent controversy over
fly-by-wire aircraft, and is pressing ahead with plans for a drive-by-wire car.
Fly-by-wire aircraft rely on software controls to a far greater extent than
conventional aircraft. Three fatal crashes of the A320 aircraft have raised
fears over the safety of such systems, and how easy they are to fly.

Saab's parent, the Saab Scania Group, has experience of computer-controlled
transport, having built the Grippen fly-by-wire fighter aircraft. Its
automotive engineers have produced a prototype computer-controlled car. The
Independent took a brief test drive yesterday. The car felt very smooth to
drive, and remarkably easy to handle, although we did only a few miles an hour.

Saab concedes that safety fears could be one of the biggest obstacles to
selling such a radical change in car design. But it predicts that by the time
the car is in production people will be more confident about
computer-controlled transport.

There is no steering wheel, but a joystick to one side of the driver. There is
no mechanical link between the joystick and the wheels a computer intervenes to
control and optimise the hydraulic steering. The car has a back-up control
system that performs the same basic tasks as the computer, but uses traditional
electronics. This is ready to switch into action if any part of the computer
fails, or the driver hits an emergency "stop" button. To steer, the driver
turns the joystick from side to side, and the computer translates this into
wheel movement. The car senses the driver's movements on the joystick,
translates these into the optimum wheel angles and feeds back information to
the driver by altering the response felt through the joystick. At low speeds,
for manoeuvres such as parking, a small movement of the joystick produces a
large change in direction of the wheels. At higher speeds this relationship
changes, so a larger movement of the joystick is needed to shift the wheels.

The prototype has a computer keyboard and flat-screen display in the passenger
seat, so the driver can modify the software to change the "feel" of the
joystick. Per Branneby, the Saab test engineer who heads the steer-by-wire
project, said: "I can make it feel like a go-kart or an American limousine."

The idea is that driving without a steering wheel is physically safer, because
you can fit an airbag where the steering wheel would be and avoid the crushing
injuries often sustained by drivers in accidents.

It should also be safer because the computer and hydraulics in between the
wheels and the joystick filter out "noise" from the road that would normally
make the steering wheel shake and judder such as stones in the road or gusty
winds.

Mr Branneby said drivers get most of the information they need to steer the car
by monitoring sideways forces on their seat. In the Saab car, the computer is
fed data from sensors that tell it about these forces, as well as the car's
speed and acceleration. The car does not sense the environment it is in, so
cannot respond automatically and change its steering to deal with a bumpy or
icy road, or a skid. This is the next stage in Saab's research.

The two-litre Saab 9000 Turbo used to test the active steering has automatic
gears and anti-lock brakes and a conventional accelerator, although Mr Branneby
said these may eventually be linked to the central computer. He does not
envisage production models of cars using steer-by-wire joysticks until 2010 or
2015, although a version with active steering applied to a conventional
steering wheel may come sooner. He also said a production model would probably
have two joysticks one for each arm so the driver can swap the arm in control.

raudona didele knopke per vyduri, pats saugiausias itaisas :) (sto pudovai, dar kur nors reset knopke turi but) ...

Anekdotas: Vazioja mechanikas su programuotoju masinoj, staiga masina uzgesta, mechanikas sako - nu ka, islipam, suremontuojam ir vaziojam.., o programuotojas atsako - o gal iseinam, ieinam ir vaziojam toliau...

Issivaizduoju kiek pinigu suede tie bandymai (!), suprantu, kad prikolas, bet labai jau utopiskas... O saip, by-wire pagal mane, tai atsisedai ant galines sedines, marsruta ivedej ir ziuri krepsyni, aluti gursnuodamas :-D
