Mapping a car - The insider

[Toeks]

Toeks, each model is connected together in what is called a communication bus, and there are various variations of such bus's, all based on a standard, the common used in vehicles at the moment is CANbus.

Say for example the gearbox module that learns your driving behavior, it receives thottle responses, so if your not somebody that floors your car from robot to robot, it will say, ok, usually max thorttle in this gear/rpm is a good time to change from 4th to 5th, and it will them make the change, but it will need variables from other modules, such as the DME which has the input for throttle reponse, and the output for RPM. ANd it can be clever, it has differant learning patterns for when you are in normal mode, and when you are in sport.

Everything is connected, and everything can talk to each other, even the radio knows what speed the car is doing, which allows it to go harder as the speed increases.

As a bit of history, the PLC, which is essentially a cars electronic system is, stands for Programmable logic controller, and it made its debut in the 70's with automakers having a problem on their assembly lines, that everything they wanted to make a change to a production line of robots/machines, there would be a major rewiring project, being hugely expensive.

So lets use a stupid example, if a robot is spray painting a car, something tells it to move a its arm in a certian position for x amount of time, if you bring out a new model which is 8mm higher in the boot area, you would have to go to a rack, find the timing devices for the spray robot, sit there and adjust the timing manually, and adjust the timing of all other functions, that says for example move the car 2mm forward on the conveyor.

This problem gave rise to the PLC or programmable logic controller, which means the introduction of a central brain, where you can adjust all factors from a computer sitting in an office or even a million KM's away, save these settings, and you never have to change a wire/input.

Our company recently did the rear section assembly for the VW Polo or the PQ24 project, and supplied the logic equipment, man you must see this stuff and what it can do, but it, just as an automotive ECU is a PLC with digitial/analog IO, its actually so elementry in how it functions, its simple... yet so powerful.

Now thats what I call a reply to a thread. Having people whom actually know what they are talking about gives credibility which just enhances the whole discussion. Now if only we had such politicians....

I'm involved with construction, mostly roads (don't hate us, we're making it better!). The PLC scenario even has application in process plants where cement and other materials are reclaimed and distributed. I was amazed at just how hi-tech these seemingly dull plants are, especially since they are usually situated between nowhere and 'nerens'. Same for mines etc. I'm sure that most people don't actually know how wired their vehicles are. Just this week I found out why exactly a steering angle sensor costs so much. The calculations involved in working out where your steering is pointing in relation to all the other DSC systems required extra processing which the DME, ECU etc couldn't handle. Which forced them to give the SAS its own cpu with memory. That explains the cost (I'm trying to hide my lack of cash behind a few "wow's!" in the name of science...)
This brings me to another questions, what can you then actually do with a GT1 system and a BMW?

GT1 is like the BMW DIS system. I am running both DIS and BMW's INPA/EDiabas sytems.

With DIS you can do coding/diagnosis, so certain features that your car supports, like DRL etc. No programming though. For that you need SSS/Progman and you run the chance of turning your car into a brick (ask me i know)

All in all, DIS is a cool system.

Ok. I know about the GT1 system but what the hay is INPA/EDiabas?

 

[clutchplate]

INPA/Edibias is the system they use in the bmw factories, you can use it to change litteraly anything on the car. coding, programmer, vin, etc.. can also write code for the modules, but the programs are quite complicated, even for a programmer, and most of it is in german. haha.

however, the INPA tool is very usefull for diagnostics.. highly recommended, you can buy the cables on ebay..
