Dashboard Linux - 1 Year Later

Posted by michael on from the how-to-raise-your-insurance-rates dept.

bergeron76 writes "It's been just over a year since the DashPC/Dashboard Linux project initially got jump started. Since then, the project has grown by an order of magnitude. The initial codebase has been released on freshmeat and sourceforge, and we're working with several other developers on integrating projects such as Linux GPS Navigation, wardrive mapping, and ODBII automobile interfacing. The potential is endless, considering just a couple of recent news headlines, and how we'd love to eventually bring them to both new and existing automobiles."

      You have no idea! I worked for GM back in the day (1973-1979), and one of the things I got to play with was the development hardware for their first CCC cars (Computer Controlled Carburetor). There was a black box that sat on the seat, with the computer (which normally was behind the passenger's kick panel) mounted on top. The black box was connected to the under-hood stuff, of course, and via a ribbon cable to a heads-up display that sat on the dash. It had LED displays and toggle switches so you could see/change various parameters. We could get those cars to idle smoothly at insanely low RPMs (did I mention they adjusted idle speed, too? little motors moving the throttle stop), but with those settings they didn't run well unless you really eeeeassed the throttle open. With those boxes you could do anything you wanted. Man, I wanted to score one for myself so badly it hurt, but they were locked down tighter than the Crown Jewels (if any got out, they'd be liable to the EPA!).

      It was in those days that I learned a bit of a secret: The computers have a "map" of the various sensor inputs -- rpm, temperature (air & water), vacuum, throttle, etc.) At any point on this multi-dimentional map were the values for things the computer controlled, like air/fuel ratio, timing, etc. They knew the "path" the EPA tests took over this map, and adjusted the settings for min. emissions/max. fuel economy while on that path; the rest of the map had settings for whatever characteristic they wanted for the car in question: performance for a Camero, drivablity for an Olds, economy for a Chevy, etc. I'm sure they still do this today.

      Actually they don't do that these days. *Very* large fines now. I work for Ford, and I've coincidentally just been to a lecture about this.

      There's a concept called a "defeat device", which is anything used to make the car's emissions behave differently in normal driving to how they would do under the EPA standard cycles. Anything can be a "defeat device", from a switch to a black box to a control algorithm to a lookup table to a single variable.

      EPA test cars on a standard cycle. However, they are also allowed to just take this thing for a drive and see how it behaves, and if it looks wrong then they can do you - particular problems are events (like step-changes) happening just outside the EPA cycles. It is then down to the manufacturer to prove 100% that the reason for that step-change in emissions just outside the EPA cycle is due to a fundamental, can't-get-round feature of the engine, and not due to a defeat device. If you can't prove that 100%, you're assumed guilty and fined.

      The essential thing to get here is the "guilty until proven innocent" bit. Auto manufacturers have to disclose to the EPA every part of their strategies which can affect emissions, and show that if emissions are increased at any point, this is either due to stopping the engine melting down or due to an essential driver safety requirement (foot-to-floor is a classic - you can give out more emissions here, bcos it's unsafe for the driver not to have torque when they're trying to overtake). If the EPA doesn't think you're right about your decisions, they can stop you selling the car. And if you don't disclose something which affects emissions, you're 100% screwed.

They're the best way of getting multi-rate processing done - for instance, there's no need to check the ambient air temperature faster than maybe every 100ms, bcos it doesn't change that fast, but calculations of engine fuelling required need to be done at the millisecond kind of timing. To do this, you split your code into stuff running at separate task rates. Interrupts ensure that more important tasks interrupt less important tasks. Every engine controller uses this system.

      Of course, you don't want interrupts to screw your data. To this end, your RTOS ensures that every task has a separate stack or that the lower-priority task's registers are pushed and popped during interrupts, and you have to design your code to take account of interrupts. For example, if a low-priority task sets a bit-field to zero and then fills in each bit one at a time, a high-priority task mustn't read that bit-field bcos it may read the value before the low-priority task has finished filling in all the bits. Embedded code has its own sets of challenges which you don't usually see in the desktop world.

In order to meet ever-tighter emissions controls and get better performance and mileage from the same engine, the processing is *seriously* complex.

    Hardware is basically free. You can get a very powerfull Linux box for under $800.

    Population growth, more cars, trucks, etc on the road means more accidents.

    Auto manufacturers will find it difficult to be able to argue that their cars are safe when they go to a pure drive-by-wire chassis (Audi).

    Eventually you will see a regulatory body for the auto industry that has the same role as the FAA/JAA with planes.

    This agency will require manufacturers to certify their hardware and software development efforts in the same manner as the FAA/JAA.
