Title: How dose the adaptive GB work
Post by: SP_3.2 on 11 February 2009, 14:10:03
How does the adaptive gear box work on these .

I'm feel very  inquisitive today and was wondering if there is a lay mans way of explaining how the system on the Autos work .

Thanks

Steve.   :y

As far as I know they're not adaptive ..... just a vicious rumour!

They are adaptive and basicaly learn how you use the throttle (they learn your rate of throttle change) and make changes to the shift points as a result.

Yep, just as Mark just said, not bad for a 12 year old design.

So what does the different versions of software do?  :-/

Would it have to relearn  after the battery was removed Mark

The key thing they do is PWM a number of the solenoids allowing better control over the shifts

???  :-/ ????
So ... if it's adaptive, when I hitch or unhitch my caravan there there should be a difference in the gear change pattern until the car's geabox ECU realises there's a difference in driving technique ie more boot required when there's a 'van behind.
I'm n ot convinced.  :-/ :-/ :-/ ... but more than willing to be proved wrong.  :y  :y

No, no sudden difference.....it will slowly adapt depending on how you use the throttle

its more to match the kind of driver you are.  for instance, mine tends to change up higher up rev range, and change down a bit earlier.  if she uses car for weekend, it changes up early, and down late.

Which is my excuse, because after the slow miles she's nursed it, being the sane and sensible driver we all aspire to be, when I do get to use it it's playtime a requirement that the car (once suitable warm) gets a "excerise" towards the higher end of the range.

I'm sure I remember being told that I should test the multirams properly from time to time.

yes mate,its the law,if they dont get used they get stuck in the same position ,which wastes petrol which in turn makes polar bears sad.
you can tell this to your mrs from me,chairman of greenpeace international. :y

Exercising them will stop them sticking ::)

How does the adaptive gear box work on these .

Thanks

Steve.   :y


It takes account of road speed, throttle position, rate of change of throttle, engine and gearbox temperature, external temperature, level of grip available, presence (or not) of a passenger and then works out the ideal gear ratio, all in 3 milli-seconds.
It then engages a completely different one.

I emailed Vauxhall to ask. They replied today with :-

Dear Andy B

Thank you for your email dated 12 February 2009.

I can confirm, following receipt of your email, I contacted our Technical Department.  They advised that, unfortunately Vauxhall Omega vehicles do not have an adaptable gearbox.

Once again I thank you for contacting us and for allowing me to comment.

Yours sincerely



Becky Lancaster
Customer Care Manager


Quite whether that is an answer to my question of - do any Omegas have adaptive gearboxes I'm still not sure  :-/  ;D  ;D  ;D

I'm sure I read in the owners hand book that when towing the gearbox would adapt to reduce the amount of shift downs that would be caused by the extra load on the engine. :-/
