flux

@GS Sorry don't know why it is a flux and I've already completed the job but if I do get any more info I'll let you know.

Gene Selkov Aug 18, 2010:

so what does it mean? Bashiqa, you should really think of a live-in arrangement with your client while you're working on this. Have you figured out what that variable does and why is it referred to as "un flux"?

Bashiqa (asker) Aug 17, 2010:

@ All I now have reply from client - VARIABLE!!!
This in fact related to a "sentence" in previous paragraph. It was in fact a logic command line or label and they are introducing a variable into the calculations.

@ GS Remeber that 'flux' here is in FR, and often translates as 'flow' in EN — and we certainly do talk about 'data flows' in both EN and FR.

As for 'mis en place', I would interpret that as 'set up' — we don't have enough context to know if it means that this is at the design stage, or if it means a specific flow is set up under a specific set of circumstances...

Gene Selkov Aug 13, 2010:

it may be a Hall effect sensor on the pedal "A la place du potentiomètre, les capteurs sans contact possèdent un transmetteur à effet Hall qui est installé de façon fixe. Sur la pédale d'accélérateur se trouve un aimant qui modifie sa position en fonction de la position de l'accélérateur."

Maybe they vary the bias in the sensor to do disable it temporarily during shifting? That would seem like a hack to me, but who knows?

Tony M Aug 13, 2010:

flux Just some thoughts:

I have often come across 'flux' used to mean a 'data flow', so I'm wondering if this might be extending that to mean a 'signal path(way)', for example?

kick down Presumably, if someone changes gear manually but clumsily, the engine will race, which could be interpreted as kick-down.

Even if this isn't an automatic box, is there something about the hybrid system that means when you kick down, the I/C engine kicks into action for a quick power boost? That would seem logical to me?

B D Finch Aug 13, 2010:

Hybrid? Too technical for me, but I do know that you don't kick down with a manual transmission because you simply change down. My mother had a car with automatic transmission and I hated driving it because I kept trying to change gear.

Gene Selkov Aug 13, 2010:

I understand it's a hybrid; the question is, why does kickdown have to be detected? In the conventional automatic powertrain, the inputs from the gas peadal sensor and the MAP sensor are juggled to guess whether a kickdown must be initiated. I am not aware of any special kickdown mode in the ordinary manual cars, but in a manually-shifted hybrid it may be an issue.

Bashiqa (asker) Aug 13, 2010:

@GS Hybrid vehicle; sport mode, motor mode or several hybrid modes.

Bashiqa (asker) Aug 13, 2010:

@BDF Thanks for your accurate explanation, I'm becoming increasingly cross-eyed with this job, carefully checking for inputs/ outputs; up/down; positive/negative etc. Flux could be a variety of devices for checking, possibly checking road speed with engine speed?

Gene Selkov Aug 13, 2010:

do we even know whether it as automatic or manual?

B D Finch Aug 13, 2010:

Kick-down Kick-down is when an automatic gear system shifts to a lower gear generally for increased acceleration when overtaking. Achieved by hitting the accelerator sharply to the floor. I assume this "flux" must be to prevent a false identification of a shift to a lower gear as being a kick-down. So, identifying what the "flux" is would require knowledge of how the detection system works.

Gene Selkov Aug 13, 2010:

In other words, it is something done to prevent the system from interpreting a regular down-shift as kick-down?

Bashiqa (asker) Aug 13, 2010:

Kick down is to give better acceleration so higher gear. This stops it changing into a lower gear. I don't think it is magnetic flux but no idea what it might be.

Gene Selkov Aug 13, 2010:

could it be "magnetic flux"? (in the motor/generator)?

I have no idea what it says, though. Do you know how the kickdown detection is done, and why should it be inhibited?
