Car With A Mind Of Its Own -- Part 2
An anonymous reader writes "As a sequel to the previous Slashdot story where a car 'began accelerating to 120 mph on its own', Renault (the car manufacturer) has examined the supposed faulty car, and as many of us have suspected, no anomaly has been found (google translation). Renault will initiate a court action to discover the truth about the matter. Read more about it here (translation)."
I personally believe the guy was full of it, on the other hand it is also standard operating procedure to deny liability first and then investigate.
Stupid sexy Flanders.
I recall the major issues concerning the Airbus A320 in the late eighties. There were a number of unexplained crashes and accidents, and both the pilots and Airbus were at loggerheads because Airbus couldn't see any fault with the software and had done everything possible to make it reliable, and the pilots - including survivors of actual incidents - believed the planes had gone totally out of control.
Well, it turned out that at least one of the issues had to do with circumstances in which both pilot and plane dealt with a problem without taking into account the other's actions. As an example, if the plane tilted to the right a little too far, the plane would immediately tilt it back. The problem was so would the pilot, and the two together would over-compensate and the plane would end up dangerously tilting left. So the pilot and plane would then do exactly the same thing in the other direction. Pilot assumes plane is out of control. Plane is just trying to correct the "dumb" pilot. Result, in some cases actual disasters.
Designers have a habit of looking at designs purely in terms of a control panel hooked up to a device. However, the control panel is an interface to a device - a human being - not the end-point of the design, and designers need to be more careful to ensure that the fact a human being will be a part of the system is taken into account, at all stages of the design. Airbus, of course, can be forgiven for being one of the first to encounter a problem with this.
Whether this is relevent to the Renault incident is open to question.
You are not alone. This is not normal. None of this is normal.
What is there to find? If there was a bug in some of the software on the car computers how would they find it since it's probably in every other Renault?
"This car is exactly like all the other ones - no anomolies, nothing broken - it's fine."
Chances are the computer would have auto reset like most do and any chance of software evidence being left is gone.
This is why cars should have black boxes.
