Electromagentic REversing Sensors

The message from snipped-for-privacy@orchardhouse.org.uk contains these words:

Wonder how well an electromagnetic system would work with plastic bollards. My suspicion is not at all. The blurb says "Mass is then moonitored..." Hmmm - that sounds very dubious.

Or trees. Or kids.

Not that you should be relying on them for reversing anyway, but if you /must/ have them at least choose one which might pick up soft targets.

They're crap. They won;t interfere with the electrics but they're no good for detecting brick and plastic.

Why don't you try learning to drive?

I've got an electromagnetic proximity sensor here & it seems to pick spick non-conductive things of that nature up fine.

Well, there ain't much in the way of computerised electrics inside a bumper...

I've not tried this type, but OEM tend to be all ultrasound, so draw your own conclusions.

@Unless you buy an S Class

Is that the one which crashed when it was demonstrated?

Nope, that was the cruise control (or not :-)) The electromagnetic ones where raising a lot of interest with high end manufacturers as you can have a clean bumper line, how well the cheap ones work I don't know, the Merc ones definitely don't cost £79. I suspect the bigger problem with the cheap ones is false alerts due to conductive things on the ground.

But it must have sensors to maintain safe stopping distances?

I don't find the present ones intrusive if body coloured.

It would seem to me they'd need a mixture of technologies to cope with this app - a bit like a combined stud, pipe and cable finder?

On my Mondeo, they're actually part of the scuff strip, so they're matte=20 black, to match the strip.

I've seen some really dodgy ones in the past, on quite high spec cars=20 too (Porsche & the like) that almost look like an after-market one from=20 Maplin.

Pete.

Dave Plowman (News) ( snipped-for-privacy@davenoise.co.uk) gurgled happily, sounding much like they were saying :

That was the one which was crashed when they tried a manual simulation of a demo, because they knew that the radar cruise wouldn't work inside the steel-framed building that they were using...
