    Well this is likely to be the last graphics intensive post for a while, although showing it off helps keep me motivated and makes me look at it differently. I'll save it for larger groups. I've changed some things in the security interface, climate control and have started and aux lighting control page. Here's the truck model I'm going to use to show a functional block- systems type approach to interface. I will include very simple systems inside of the body such as engine, brakes, cooling, ac. This has been an interesting indoctrination to graphic art, it's kind of fun, but I wouldn't want to do it long term.

    I'll post the first pic with maybe a chassis, an engine, and the cooling system to show what I'm imagining soon. So if the ccoolant temp gets too high, the system will go from its normal color to glowing red on the cruising and tuning pages. The same for all of the other systems that I include. Things like the gas tank will show its level, where it is, in the tank. No way this is getting done by december. Damn, I really wanted that 25$







    I plan to make other vehicles for other people to use if they want them. They'll be just as simple though.

    I am a big fan of the new temperature display with only red and only blue sections! Looks great!

    You must have spent a lot of time on that truck!

    Yeah I did spend a lot, but I think it was a wise investment, You'll laugh when you find out what my graphics editor for it was.

    Yeah for the slider affect, the right bars will either appear or re-appear as seperate images in the 'control'. I think.

    h3rk,

    I'm really liking the AC skin a lot. The red and blue looks very nice and would fit many autos out there.

    I have finally had some time to start digging into the FB. It has sat here on my desk for quite some time.

    Thanks, I'm pretty satisfied with it as well. I'm probably going to leave the design alone on that page, and move on to the other aspects next. I'm working on the diagnosic/tuning/cruising pages right now, it's taking some time to build the right images.
    The only thing that I can see changing on the AC page is the bubble man, he was my first 3d thing I did on the project (ever), and I think I could probably do better now.

    I think if you kept the shape of "bubble man" combined the objects so there isnt that overlap with knees, torso type thing, then it would like perfect!

    Well I hope my 'bubble man' fix is ok. It's harder than I thought. I've been limited to what I can do with illustrator, psp, fireworks, PS, And powerpoint, like I said all the 3dish stuff is from powerpoint, it has a lot of limitations basically everything is an extruded and beveled shape, with different material, fill colors and lighting. The way I have to group stuff so they rotate together is a pain in the ... Like with "bubblejerk' over there, I make a freeform object to get rid of the overlap, but then I wouldhave to make 2 torsos to get 2 legs, I cant bevel anything but the edges, in fact the fact that I got so far on that truck just kept amazing me really. I've been playing with acad2007, but it's pretty complicated. There are, however, a whole lot of tutorials online.

    At this point, that 3d frustration has pretty much got me pulling my hair out. I'm going to try to go back to putting all of my pictures where they belong (FCC) and start trying to give them the function they need to have. I gave mastero a pretty long description of what I would like the new aircon to do, and automatic AC is not exactly as simple as it may seem to some.

    So I'll get back to the AC page, first as if it were it's own skin, I'll try to get it to do what I need it to do, and we might benifit from a new group disccussion thread about how we will implement these things (back end support and such) for air conditioning. I'm interested in seeing greenman100's writeup. There's some calculating, estimating, and stuff. I don't really what my limitations on the skin side are going to be yet, but I'm sure that soon I will.

    For those who haven't been following the aircon thread, here's some things I want to tackle with automatic AC control.

    Automatic control brings to the table some interesting challenges, people are going to expect to be able to set a number, representing a desired cabin temperature, and have the climate control sustem do whatever it takes to achieve and maintain it:

    First, it can be all but guaranteed that linear control of the blend damper will not provide linear control of the the cabin air temperature.

    Second, perceived cabin air temp will not always (or often) feel like actual, as sensed by its designated sensor. When the sun is out, it will frequently feel much warmer. Ambient temperature will change the perceived temperature as well. The effects of these factors on perceived temperature are not insignificant, and must be accounted for. So there needs to be a curve, or a map for the error signal driving the blend damper and fan that takes sensed cabin air temperature and corrects it with sunload and ambient temperature. More on this in a paragraph or two.

    Due to high heat transfer rates from the vehicle in moderate to very low temperature, fan speed should be increased in addition to the driving signal above solely due to outside ambient air temperature. The same is true for periods of high sunload and high ambient air temperature.

    All of these factors must be weighted and the amount by which they are weighted will vary greatly based on the different models of climate control systems (air box/ damper geometry, fan curves, etc.), and models of vehicles.

    Now, in addition to the above, one final factor should be added, or multiplied to this error signal before it drives the blend door actuator. That is a factor representing the non-linearity of the dampers effect, through the fans airstream, on cabin temperature.
    Where do we get these factors from? Auto manufacturers have the luxury of all their testing, using the automobile itself, the airbox, special wind measurements, heat transfer data, and years of experience. We obviously don’t.

    My first idea paralleled this however; come up with a simplified, general way of determining ft3 and glass ft2 fan efficiency, etc. and way to gather this data in a software wizard. There were some holes I couldn’t fill with this method in my mental walkthrough of the occasion.

    Empirical Data:
    In my years of experience in industry, I’ve found that my theoretical knowledge can not usually compete with more experience and empirical data. With this thought in mind, I turned to the idea of a calibration sequence that uses the things it knows (temperatures) and finding things it doesn’t know (factors). With some assumptions and generic models, I think that can really complete the equation for most applications.

    And since I’ve touched on extreme temperatures, I should also say that many behicles have an evaporator (anti-frost) thermostat which interrupts power to the compressor when close to freezing temperatures exist there. Refrigeration pressure switches, as with manual systems, are obviously required still.

    To round out compressor shut offs, the compressor should shut off when temp gets too high, or on full acceleration. (which brings to mind another dilemma in determining which functions like these or parts thereof are performed by each vehicles engine controller and which are performed by the climate controller. Where is the line drawn?)

    Regarding compressor shutoffs: Sure these switches can be wired in series with the compressor, but:
    When we install these new controllers, we become the only qualified technicians for them. This introduces the concept of error codes to this application. We’re not going to send them to the diagnostics port anymore, like current automotive auto climate controllers do, but there’s no reason we shouldn’t have them available. Hell, we’re taking the diagnostic information already there, and putting that on the carPC anyway.

    A few more quickies:

    How are we going to get this thing to tell the ECU to make the engine idle faster when the AC compressor clutch energizes?

    High end systems will also redistribute air based on cooler (face) hotter (floor) More than 4 fan speeds are needed for that smooth ramp up and down, a must for precise control anyway.

    The signals to these motors is varied, how do we account for all?

    I have more, but I'm going to try and get back in the groove of this for a little while first. Goodbye real world

    Ok I light of some new changes to the fusion software, I've pretty much erased the skin drawing board, and thought I'd do some things that will take advantage of some of the overlapping technology that has been recently introduced (made possible by 2K1Toaster working through some of his holiday island vacation).

    The initial idea was to have all 4 areas work something like a game of simon. push the fan control area and on the opposite side, controls are made available for the blower. I think though, 1 tap, and buttons can appear over top of the graph to allow interaction.

    On the top-screen indicators, I think it will work that way. press up there once, and the bottom area will fill up with buttons like what I had on the left of the old version (only more transparent). Once a mode is selected, the temperature graph returns (or also on a time-out, hopefully). I'm still working on the basic idea, but I thought I'd share it and get some feedback on whether this is a more desirable direction to go.

    The buttons that are overlayed on the graphs will appear on mouseover (or something like pressing once, whatever the touchscreen and the program will agree to) and will time out.

    I know now that I tilted the temp graph I'll have to re-do the blower one too.

    here are two, where the only difference is the background image.
