I agree with switchlogic…its intrusive its penny pinching and just another big brother tool, thank god i dont have to put up with that bollox…only another 18 months and im done, it gets dafter by the year incab cameras …microlise…digital tacho’s…wot next a chaperone sat in the passenger seat telling you wot to do ? oh and dcpc , wot happened to check the truck over and get in and do your job ? A to B to C… i dont envy any young fellas coming into this job .

Does anyone know how accurate this is?
I am in a disciplinary next week for 3 over speeds none of which registered on the tacho.
Is it linked to the speedo/tacho on the vehicle or is it seperate?
Does it need to be calibrated regularly like a tacho?61.33mph for 21 seconds
61.64mph for 24 seconds
61.89 mph for 16 secondsI find myself looking at the speedo and tacho more than the road at the moment.
Is it a disciplinary or an investigation? You should have a good case to get it thrown out if it’s not registering on the tacho, after all that’s what gets calibrated along with the limiter. Does it happen all the time? Was it a different truck?
The trouble with microlise is that it automatically logs an overspeed once you reach 60.1 mph. Whereas a digi can be run off the clock but won’t register provided you haul it back under the minute mark

Call that speeding

We had them fitted about 18 month ago and we had to change our driving style at the time ie using the manual change on our autos a lot more [Daf xf] to get the best out off them but its second nature now dont even think about it but can be a pain trying to stay in the green band,but from the company point of view they love them, on our night runs they are saving about 20 litres of fuel per truck x 10 trucks per shift
Here’s a contriversal thought why not spec manual gearbox’s

+1,speeding is off the clock coming down the 66 at stainmore at 44ton,microlise that ya bam 
+1…put the hammer through it…wire cutters end of …
You’re making mountains out of molehills here guys. I’d hazard a guess that the guys getting picked up for overspeeds are employees who are paid by the hour. Well it’s the companies train set to play with and if they want you to slow down then slow down. It needn’t be a drama. Eventually they’ll tire of their new toy anyway and move on to something else.
we have it every now and again i get a phone call about how im doing the main thing i get told about it over revs when pulling away i personally put this down to the fact that the gear box in my daf xf ( 3 over 3 ) is a pile of crap when trying to get going with weight on once it get goin its great but i just find it so clunky in the lower end of the box
the lads at the top of the table are all in volvos with i shift or 3 over 3 scannys
We have a similar system, Navman.
It register over revs, anything over 2000 rpm…which is great until you use the exhaust brake!
It definitely records overspeeds at 60mph…but if it is a gps based system then i know that both my speedo and digi over read when compared to my sat nav, i.e. 60 on the speedo is only 58/59 on the sat nav…so as long as i keep the speedo needle the right side of 60 i’m hoping i should be ok!
I have the cruise control on the Actros set up to 90kmh +4 so that it kicks the exhaust brake in at 94kmh, the minute i see/hear it kick i tickle the brake pedal to drop it back a little further so that i don’t go over 60mph.
Idling is a different issue, as i am not sure whether our system differentiates between PTO use and normal idling…can be a problem when tipping at a farm into a barn where you need to keep edging forward while raising the body to avoid clouting the low doorway!
IMHO a better system would be to display and sound visual/audible warning once 60 mph is exceeded giving the driver 30 secs to bring it back down before recording an overspeed at 62…the Police will not take any enforcement action at 61, 62 etc…they are normally bound the ACPO guidelines of 10% +2 mph, so theoretically you would not be ticketed/prosecuted until you hit 68+!
It is a massive hammer to crack a nut to discipline drivers for 61 mph…although if your speedo over reads compared to your sat nav…you might want to think about that before going down the calibration route…having said that…there are spots where the GPS reception isn’t great and that can obviously affect determination of speed.
I quite often glance at my sat nav to see i am doing 50 mph, but the truck is still on the limiter…all down to patch reception…which is why the Police do not use GPS based systems for speed enforcement! Cannot be calibrated accurately enough for evidential purposes.
If there are no overspeeds recorded on the tacho, then i would be tempted to say that my speedo never showed me exceeding 60mph and let them prove that it did.
DonutUK:
We have a similar system, Navman.
And what a crap system it is. We’ve got it too. I have the same problems when using the exhaust brake. Over rev warning appears on the screen.
But then I suppose that’s all to do with the parameters that the gaffer has set it to.
Idling is another sore point. I got asked why I let the truck idle for 75 minutes recently. I didn’t and would never idle for that long. Fortunately another driver got pulled for the same thing. Just so happened he was on his assessment that day so the assessor backed him up to say that he never let it idle unnecessarily at any point. Some days it says my average fuel rate is only 3mpg then other days it rises to 20mpg!:■■?: So now they know it’s a flawed system but they still insist we use it.
I never use the satnav side of it as its the worst one I’ve ever used. It has routed me through housing estates before.
Oh and another thing. As its plugged into the OBD socket, it sometimes sends speed signals back to the trucks ECU and bizarrely makes my wipers come on of their own accord.
You have 2 devices in the truck allready monitoring your every move and in a lot of trucks now tracking, why another pile of kak…if someone rang me up and told me ive over revved the truck by a few rpm’s i know wot the answer would be…concentrate on the job at hand driving not looking at stupid gadgets and fretting about it, why do drivers put up with this garbage…are they frightened of opening there gobs…never been a yes man never will be either…all this so called hightech crap isnt helping the driver in any shape or form. 
switchlogic:
Reading stuff like this and seeing disciplinaries over three piddling overspeeds makes me realise how lucky I am in my current job. I fully expect this to be my last driving job, couldn’t hack all that stupid bolloxs
Lucky man. I’ll keep searching.

Not really a molehill, I have been told by the guy doing the disciplinary that they have a three strikes and your out policy.
Three over speeds per disciplinary, three disciplinaries and your gone.
So I could lose my job for just nine over speeds.
Oh and I am salaried not hourly paid
I know nothing about this system, never seen one.
So, as far as overspeeding goes, does the device show the driver a speed whilst in motion or does the driver still have to rely on his speedometer?
If so, and the tach shows no overspeed how does the driver get to control the speed of his vehicle if 2 instruments used to check it are showing 2 different readings?
Sounds crazy to me!
Like many have said before all this gadget watching MUST be making the driver more likely to have an accident.

The ones in ours have no displays at all, we just have the speedo to go by.
so the microlise could be reading faster than the speedo for all I know.
So in that case a driver could only be expected to drive according to the information he had at hand, i.e the speedo, so if this shows no overspeed then I fail to see how he can be held at fault.
