"Funny that, because the above functionality (inhibit when going around a corner) was how the system was described to me by the senior engineer at Ford responsible for running a recent major vehicle programme (or three) incorporating this feature."
Could be. S/He was probably talking about the Jaguar system. Curves can be an issue, as Mr. McIntyre points out with the BMW. Usually the system use information from the stability control to tell you that you are in a curve, and the radius of the curve. This lets it know which vehicles are in its lane and which aren't. Unfortunately, you only get this information when you're actually in the curve, and not before it.
However, there are ways to minimize this effect.
Besides, they (OEMs) don't make them, we (suppliers) do.
In any case, most systems do not turn off in a curve.
A couple of other asides:
- The picture of the Ford vehicle is a Flex, and not a Mini.
- Volvo is using lidar, not radar.
- Some OEMs use 24GHz, which is the same frequency as police radar in the States. Some radar detectors will pick this up. Lidar being used in some systems will be picked up by some lidar detectors as well. Heck, even LED brakelights set off some lidar detectors. Don't speed, and it's not an issue.
- Some use 77GHz, which is not an issue.
- Good luck trying to use the 24GHz as a police radar jamming device. Let me know how that turns out for you.
- My first boss suggested spikes on the steering wheel 20 years ago. It's still a good idea, but remember, people still get in accidents just sitting in traffic, minding their own business.
- With the way we have all seen people driving, FLYING CARS ARE A BAD IDEA. I still want one.
