…linux cars? Pretty please?
Vehicle control systems are overwhelmingly programmed in C, mostly from graphical design tools such as MATLAB Simulink via an automatic process. These are real time control systems which are quite different to an interrupt based operating system such as Linux. The many individual controllers must work in concert according to a strict architecture definition and timing schedule that defines the functionality of the vehicle. It’s not at all like a PC or phone, whose OS become irrelevant over time, with respect to their environment of other systems. The vehicle environment is the same environment that we inhabit i.e. the one with gravity, friction, charge and the other SI units. This is slowly changing with advent of self driving but, yeah.
God no
When you car can connect to the Internet, it becomes a data-mining tool that tells everyone your business. Companies would LOVE to have all that juicy location data that only Google has right now (from your phones). Insurance companies would LOVE to know your driving habits to have any excuse at all to jack up your premiums.
Locked bootloaders should be illegal. Manufacturers should have to provide enough specs that third parties can write code that runs on the hardware.
Without right to repair, there will be planned obsolescence.
My Citroen EV developed an on board charger fault. It wouldn’t charge. The part was a “coded part” which meant it had to specifically programmed with my EV’s ID by Citroen at manufacture. It took months to finally be fitted and ready. So basically, not only does the coded parts system make service shit, but also means when the manufacturer is done making the part, the car is dead. You can’t swap parts between cars and there is no third party parts. It’s meant to be about car theft, but it’s very convenient it blocks competition and long product life…
What’s wrong with just a pot box, a motor and some batteries?
The main issue is that the NHSTA requires a backup camera, which requires a screen. Since they have to make room for that screen, manufacturers now want to make it a premium thing they can use to justify up charging.
I don’t see a solution to this until someone actually tries to make things cheap again and small screens become the trend.
Is that a new rule? For all cars?
If by “new” you mean decided a decade ago and implemented 6 years ago, then yes.
I didn’t know. Maybe it’s not a law in Australia or I just haven’t been paying attention as my '96 Magna is still going fine.
Luckily modern cars are generally a lot safer to drive than your old magna. Air bags (not new, just better), crumble zones, automatic emergency braking, lane assist/departure warning etc. have come a really long way in the past 30 years. They’re not only less likely to be in major crashes, they’re also safer for both people in the car and outside the car (bikes/pedestrians) if it happens.
I dream of an open source car. Something simple but reliable, say a legally-distinct 2004 Honda Accord, bog standard, no frills, no detail package options, just A Cheap Car with standardized parts and open source software. It’s the only car the company makes, you can buy one for 10k or build your own for 6k out of parts and a couple months worth of weekends, car nerds will fork the software for infinite tuning customization, and it doesn’t report your location back to headquarters. Parts are standardized across every car we’ve ever made so your local parts store will have them in stock. The new model year is the same car as last year, we just built some fresh ones for people to buy new.
I have no way of making this dream a reality. But I dream of it nonetheless. American car culture has gone off the rails, and the number of people I see already driving around old 5-owner Hondas and Toyotas and Buicks tells me that there is definitely a market for a cheap basic car that runs.
That would have been the Sono Sion, but there was too little interest. Not enough preorders meant they ran out of money to continue development.
Off topic: I’d argue Love Exposure by Sion Sono is the best movie ever made.
Creating a FOSS EV is all do-able right now with off the shelf motors and batteries. Welding a frame would take some skill. How to title it would depend on the local government rules; many states in the US have a kit car designation for this sort of thing, but not all do.
If it’s built rigid like a race car with a roll cage, four-point harness, and at least a DOT rated helmet for everyone inside (if not Snell), it could be safer then most cars on the road. If it’s not very large, then it’s probably safer for pedestrians and bicycles, too.
I don’t expect air bags to be viable. It takes a lot of tuning to get them right, and they can be worse than nothing if not done right (they’re basically a controlled explosion). However, the race car-like design above, plus helmets, would keep you safer than any air bag. Road cars converted to track cars often disable or remove the air bags. The rules of the event may even require it. They’re counterproductive dead weight when you’re packed in this way.
Other creature comforts are going to be what you put into it, but keep in mind that many of the things we take for granted in modern cars–A/C, stereos, padded seats, etc.–add a whole lot of weight.
What also adds weight is how many passengers you want to carry at once. Two passengers won’t add much weight, but four or more would. All that extra frame material adds up.
Building a traditional frame would take some welding skills. I have just enough welding skills to make some shelves, but anything structural (which my tutor defined as “anything where somebody’s life depends on the weld holding”) is not something I’m comfortable doing. That is to say, it’ll take more than a quick tutorial and a little practice.
However, one interesting possibility is epoxy. Lotus did this for the Elise, and I once tracked down the epoxy manufacturer they use (I’d have to search around to find it again, though). The instructions for it didn’t seem to need anything particularly out of reach for a hobbyist (doesn’t need a big autoclave or anything like that). Lotus did reinforce certain sections with bolts/rivets. It will take some knowledge to design a frame around this, but it’s one time design work by an engineer and then everyone can copy it.
One advantage Lotus had over a welded frame was thinner material. A weld itself is very strong, but it weakens the metal around it (meaning you usually get breaks around the weld, not on it). You have to use thicker metal to compensate for that. Since Lotus was using an epoxy, they could use thinner material for less weight, and it was stronger in the end.
Since it’s also getting rid of a whole lot of weight around the frame, the range you get out of those batteries could be extreme. It could also be extremely quick with a modest motor.
This is basically all to say that you can have any three: safe, creature comforts, enough space for passengers, range.
And this is why I drive a 1980 Volkswagen rabbit pickup. better gas mileage then modern cars (50mpg+ on the highway) I can replace about any part in it for under a few hundred in most cases even a new engine can be done under 1000. And everything is dead simple to work on no fancy computers or anything.
Polluting as hell though, or so I imagine?
Even in Sweden catalysators were not mandatory before like 1986 IIRC.
The rest is awesome though 👍😎
Oh yea it’s a straight pipe diesel ain’t anything good for the environment gonna put a slightly more modern engine in it at some point for some more power the 1.6l in it currently only makes like 50 horse so when I do that it’ll be a little better but still not great
Well there are a bunch of reliable late 90s and early 2000s German engines that would make that thing ridiculously fast compared to now, pollute less, burn less fuel, and would be pretty easy to maintain.
Long as you avoid all the ones with known pitfalls and research standalone ECU options first of course.
I’m partial to Mercedes engineering myself, I’d tell you to use an OM646. But there’s nothing wrong with an M47 or a VW 1.9 tdi either. The PD version of the tdi is slightly more complex than the oldschool versions (66 and 81 kW), but would get you ridiculous performance and fuel economy considering how little your car weighs.
Of course if you had more space in there, I’d suggest an OM648 or M57, but I don’t think you’d get an inline 6 to fit. MAYBE an OM647 since it’s an inline 5?
You can get a inline 5 in it cause I know you can fit a o7k or a vr6 lol. my plan was to swap it to a TDI I actually have an 01 TDI sitting here for it just don’t have the money currently to finish it but once i do, this TDI is actually supped up some pushing 20+ psi of boost not the I will probably run that much since I plan to daily it but it can
