Dashboard Linux - 1 Year Later 109
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."

I think big changes are coming in the auto manufacturing process.
Here is why:
There are more man hours spent in cars than airplanes.
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.
The avionics hardware and software guidelines are called DO-160 (environmental), DO 178B (software) and DO-254 (complex hardware), and are published by the RTCA.
This process of certification for the "auto-onics" will be present to ensure that the car is safe, and can be sold with limited risk to the passengers.
This is especially important any time you get into a situation when you are talking about cars driving themselves. Which I have no doubt they will be able to do.
Discussions regarding the certification process of open source collaborative software would certainly be interesting.

If you want to know everything your engine is doing, you owe it to yourself to move to a complete engine management system such as those sold by haltech. I picked them because they are the first brand of ECU which I discovered would easily support the nissan crank angle sensor. (It has 90 degree marks, 0/180 degree marks, AND 1 degree marks.) There are certainly other companies making them. They generally have a serial port which you connect to a laptop (assuming you want to do things on the road) and you can adjust fuel maps and such in realtime.
The project toward which I am schooling (at yuba college [cc.ca.us] in marysville) is creating my own EMS. I took a class in assembler, I'm going to take a few in electronics, and they have a nice big auto department so I should be able to go learn plenty about fuel systems and ignition systems. Complete engine management systems generally cost around $3000 (or more) and I want one much cheaper :)
I think that people should be putting effort into creating a "free" (as in unencumbered) engine management system design for cars. I am not planning to do this however, I want to produce a commercial venture and hardware is not software! However if I do successfully complete this project before I get bored with it then I intend the source to at least be open if not free.

OBD-II is, I'm sure, sufficient for what most people want to do on their dashboards. But as I said, most of the cars which are interesting from a hacking standpoint, the cheap powerhouses, don't have even OBD-II, let alone will they have CAN.

If we were about 5 years earlier, I would agree with this, but the Import tuner scene is really coming on strong, and computers control all of their fuel injection systems. This also goes for the current US domestic sports cars (Corvette, Mustang, formerly the Firebird/Camero (RIP)). These are mostly driven (currently) by ODBII. The Toyota Supra (RIP) is one of the most tuneable machines made in the past decade (IMO), and can be turned into a monster HP machine without a tonne of work (it's amazing what you can force feed that 3 litre engine without it complaining). Dittoes with the Nissan Skyline, which we (unfortunatly) don't have in the US from Nissan. (Yes, I know that there is an importer, and there are ways to get it. Don't flame me for it.)
One of the cool things about having something like this is the lack of dependance on a proprietary computer that has a huge price tag for auto repair shoppes. I work with one currently, and they gave $5k US for their current diag box. Fortunatly, they got one that was current enough that it will be able to read CAN devices with only a firmware update (I believe that the cost of this is a couple of hundred as well, however), and won't need to purchase an interpreter box (which does exist, also a couple of hundred, by my understanding), or replacing the unit altogether.
Another is being able to adjust feul mix with the flip of a switch. Need more juice when you force feed the unit heavily.

P.S. The Skyline doesn't count, it costs too much in the US due to the low volume and the significant (one assumes) amount of money motorex invested in legalizing them over here. Sweet ride, but I'm more excited about the Lancer Evo VII which all the car mags insist is coming here for 2003 at (they claim) 250hp. Not as much as the JDM version, but more than (say) an Impreza WRX. And as goofy as the Evo looks, the headlights on the WRX just make me laugh. It looks like a neon porked a sunfire and that was the result.
I maintain that what the world REALLY needs is an open/free engine management system using inexpensive off the shelf components which are familiar to the majority of people capable of working with such systems. I would suggest some kind of motorola processor that would give way more cycles than you could possibly need and enough I/O to control TWO engines, that way you could do any damn thing you wanted to with it. The hardware couldn't possibly cost any more than $500 and that would be a dramatic bargain as that costs less than modifying some ECUs for chipping.

Plus, there are certainly other EMS's available for less than the $3000 range, such as the Haltech [haltech.com], Microtech [thedynoshop.com], and even the Megasquirt [bgsoflex.com], which, while not unencumbered, has at least source and schematics available.

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. Aftermarket computer ROMs [rpmoutlet.com] are using the same trick.

Re:Kudos to these folks (Score:2)
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.
So far, fines have been relatively small, $100 million max. Toyota however are currently fighting a case which, if they lose, will cost them in the order of billions of dollars. Bad news...

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.
Incidentally, the "relatively simple" embedded system is no longer simple. In order to meet ever-tighter emissions controls and get better performance and mileage from the same engine, the processing is *seriously* complex. On my current project at work, we're currently using a 32-bit processor with floating-point support running at 32MHz (for the record, that's a pretty high-end embedded controller), and we've had to do some *serious* hacking to get our application to run in real-time at full RPM!

There are infinite counting numbers (integers >= 1), but they don't include the negatives or 0, but they are still endless.
Anyway, you can see my point. Just because you can name two or three things that our not in a given set, doesn't make that set finite.
To take it even further. thet set of all possible numbers is also not all-encompassing. It doesn't include the letter 'A'. So, it's still a matter of domain. The possibilities can only be infinite, or endless, within their domain.
