MMI interface info.....
Went digging around and found some info about MMI. For those who would really like to know how MMI work and why it works the way that it does.
This is from Babelfish German to English
mid Munich - future will take place 90 per cent of the innovations in the motor vehicle within the electronics range. The software will have a portion of 80 per cent. The car manufacturers will obtain 35 to 50 per cent of their creation of value with electronics. The avowed Willibald Schleuter, leader electronics/electrical connection with AUDI, within the framework one ` electronics auditory ' in Munich. Electronics became with AUDI the core authority and is to offer an increase in comfort, information and security to the customers above all.
AUDI stands directly before the introduction on the market of a multiplicity of electronic functions. Apart from the development of the Infotainment systems up to the InterNet integration vehicle authorization and Personalisierungssysteme are ready for the market. In further consequence also an adaptive headlight system is to improve the view conditions for vehicle steering wheels.
First those becomes variety at information and maintenance systems, which AUDI already offers in its present models - navigation/telematics, audio and video - for the customer is made better manageable. ` the operation of the current function range reached a complexity degree, which is felt of many users as user unfriendly ', explained Werner Hamberger, project manager of control concepts with AUDI. After several experiments - among other things with one ` Touch screen ' - AUDI developed now a multi Media interface (MMI), which the driver can serve after a learning phase practically ` blindly '.
A further stage of the Infotainment development will be the introduction of ` InterNet in the car '. The technical basis for this - a mobile data link between vehicle and external world - is present since the introduction of AUDI telematics in the autumn 2000. AUDI the on-line portal exists already, is not however yet generally accessible.
From marketing errors others learned the Ingolstaedter obviously. Differently than during the introduction of WAP, which as ` mobiles InterNet ', which user disappointed and therefore the Flop became, emphasizes the experts of AUDI Infotainment that ` the InterNet in the vehicle not with from the Home PC did not admit of Surfen in the WWW to be equated is ' - already at all during driving. On the basis by InterNet Technlogien such as Browser, data minutes and safety solutions an information and a communication platform adapted to drivers, vehicle and road one offer to the customer. The efficiency depends on the communication procedures of the portable radio; from today's view this would be mainly HSCSD (High speed Circuit Switched DATA) and GPRS (general packed radio service).
InterNet in the AUDI will lie from its resources between a Handy and a PC. For the representation of contents on a monitor with 480 x of 230 pixels the HTML sides are prepared by own conversion mechanisms. Basis is the Unix similar real time processing system QNX/Neutrino, which is according to data of Ricky Hudi, leader Infotainment with AUDI ` flexibly, durable and reliable '.
Apart from the reliability also on simple operability value put, because the system by the customer am only accepted, ` if the user interface top one developed and very simply is.'
The concern that the fast development of the information and communication technologies with product life cycles partly runs away under one year of the life span of a vehicle to a certain extent ` ' and the customer has in the long run an outdated system, absent-minded Hudi: The hardware is modular developed and can be renewed therefore without special expenditure; updating of the software is still simpler: Here the new releases are brought in simply in the course of remote maintenance.
For introduction on the market Hudi did not want to express itself concretely: ` the InterNet in the AUDI ' will come ` with the new publication of a next large model ' and then in other models be expanded gradually, explained it opposite ` mid '. The price is first expected ` smaller to be, than one '.
With vehicle authorization systems a comfort increase is imminent. ` the keyless ' system Keyless Entry/Go, with which the vehicle key must be only carried in the bag, but neither be used actively for unlocking the vehicle door, nor for starting, is supplemented by a biometric Personalisierungsverfahren, which on the uniqueness of the Papillarlinien on the finger crests of the human hand - which finger prints - is based. Sensors ` read off ' the finger mark within a tenth of a second; the actual recognition takes about a half second. The prints several fingers are stored, so that also for the case the identification functions to an injury.
For the time being this Personalisierung is only one contribution to increased comfort. If electronics has the Fahrerin or the driver ` recognized ', air conditioning system, radio station etc. stop themselves seating position, vehicle mirrors, automatically to the person. For the first time the recognition with finger print is offered ` in one of the next vehicles ', to formulated Carsten week of the AUDI range in relation to body electronics ` mid '.
The Ingolstaedter does not see the use of the finger mark as going away barrier or for starting the vehicle ` at the moment yet as feasiblly on '. This is a question of the customer acceptance. Who wants to take in the winter the glove off and to press the finger on a ice-cold metal panel.
A further innovation presupposes change of the European force driving legislation: The introduction of a tiltable headlight low beam is to illuminate the ranges of vision - instead of like today mainly the edge of the lane -, relevant for leading the vehicle, when driving through curves. Wolfgang chicken, leader development lighting and switch, lapidary on ` the mid' question whether tiltable headlight low beam the steering wheel accomodating vehicle to irritate and do not believe make can, which would come others directly to it: ` that is Problem'.Peter Kudlicza/mid mid/kud
I actually found a CV of a person who was one of the designers of MMI!
In assignment of MegaPart GmbH, Karlsruhe, for Siemens VDO automotive, a large automotive supplier, in Regensburg. As team leader of an integration team of 5, I was responsible for the software integration of the head unit of a new infotainment system for Audi AG (4500 source files for 2 processors). The head unit additionally contains a tuner module as well as a navigation module, and communicates with external components through a MOST ring.
The challenges were to newly structure and define the integration process, to speed up both compilation/link times as well as the integration times, and to increase the stability of the system by specifying a set of guidelines for the merge process.
In addition, I have actively supported the debug team on various occasions.
Technical environment: SH3 and ST7 processors, Operating System VxWorks, Wind River 'Tornado' development environment using C++, Rational ClearCase configuration management, Clearmake/GNU make, IDL using self-made tools for class generation, UML using I-Logix' Rhapsody. Debugging using CANoe/CANalyzer from Vector and OptoLyzer from Oasis. Defect management using Rational ClearQuest. Documentation using Microsoft Office. Workstations Windows NT4 SP6a.

I just looked up QNX software systems.....
You folks are definately better off then the BMW folks who have windows CE in the backend....
Just reading through more of this stuff....It seems one can attach an Hard Drives or USB devices to the MMI interface...Its all plug in modules....<ul><li><a href="http://www.qnx.com/products/ps_neutrino/prodbrief.html">http://www.qnx.com/products/ps_neutrino/prodbrief.html</a</li></ul>

We've been using QNX in our real-time controllers for 6+ years..
in our aircraft alignment systems and our drilling tools that the company I work for makes. The OS is very stable, great for real-time systems. We've even made a Linux OS emulate some of the real-time features of QNX. We've have tools that have been running 168/52 for over 5 years w/o any OS problems. Good to hear that Audi is using it, now they just need to do a bit more work on the software ;-)
