The best car OS so far (even better than Tesla IMO) has been Apple CarPlay. Just be dumb and let my phone handle it, and make the touch screen decent. Bonus points if you implement the multi screen CarPlay concept! Just give up!

Mazda is great at this. They don’t pretend to make better software than Apple. They just give you nice hardware interface and a reasonable screen that you don’t have to touch to manipulate it while driving a large chunk of metal very fast.

> Will I really be able to get replacement parts for the Sprinter when the screen or computer start to die in 10-15 years? Most likely, yes. Part of why most automotive tech lags behind the times on raw performance is guarantees around things like how long you can source a given SoC, for example. 10 years is not an uncommon manufacturing lifetime in the space, and a Sprinter is a relatively high volume car so I would…

I wouldn't count on it. I work for John Deere, and am often in discussions about some part going out of production. Sometimes we guess how many we need for the next X years and buy that many, othertimes we rewrite software for a new part. Care to guess how many boards can sit in a warehouse for many years and still have good capacitors. I can't tell you how many years, but there is always someone in these discussions…

I work on automotive HMI and don't have to guess how many can sit in a warehouse for many years and still have good caps.

They're subject to a lot worse than that for design verification. And I assure you John Deere has many _many_ PCBs that have sat for 10 years to enable service needs today, it's not like they just started using complex circuit boards yesterday...

This is the saving grace. And luckily, the next generation CarPlay will span the entire dashboard, including in front of the driver [1] I can’t wait to abandon my native “infotainment” cluster** [1] https://www.macrumors.com/2022/12/28/next-generation-carplay...

This looks amazing, tbh.

Looks stunning, but no thanks. I want analog dials and physical buttons and knobs for features like gauges, air conditioning, and volume.

I just found this presentation with technical details: https://group.mercedes-benz.com/dokumente/investoren/praesen... I guess it is not a typical OS, but more like a collection of tools that build on already existing OSs. This is comparable to ROS (Robotic Operating System), which are just some programs, middleware, services and conventions to build software for robots on Linux. It seems like this should integrate a…

Just a nitpic, Linux can run on CPUs without MMUs, and it has APIs for locking memory and real time scheduling but that's not why it is not a hard-realtime OS.

Yes you are correct. I am currently having a project, making Linux "as real-time as possible": locking memory with mlockall, isolating cores, preempt kernel patch, .... It is still not real-time because you have no guarantees, but you typically get a max jitter of 0.1 ms, which is good enough for my use case.

You could use Linux without a MMU (uClinux), e.g. on a Cortex-M, but is a horribly experience and no standard program works.

In case anyone here weren't a farmer, John Deer is the Apple Tesla of industrial equipment with not just built-in planned obsolescence but built-in inability to self-repair or self-diagnose without proprietary equipment. Much hay has been made in R2R about John Deer's customer-hostile practices. The harvest time sensor reset tax is why some small-time farmers stick to old and overseas equipment they can repair withou…

Exactly: farm equipment is one place where you really do not want to Buy American.

Umm, no. I tried their Drive Pilot L3 system in Germany over the Christmas holidays (MB EQS) and of 8 hours driving, it was only available for me to drive for 12 minutes (and not a continuous 12 minutes, either). Granted this does not mean the system is poor quality, but it's horribly impractical... if it's rarely to ever available.

It sounds like they are more responsible than the other companies.

Exactly. Using your customers as guinea pig data collectors for an undeveloped system seems to be the go-to. There have been noted fatalities due to this.

My (admittedly-beloved) 2015 F-150 will reboot Sync if I'm listening to music (usually on Soundcloud) if the song title includes non-ASCII characters.

I'm reminded of: ( https://99percentinvisible.org/episode/the-roman-mars-mazda-... ) the Mazda head unit being allergic to Roman Mars.

The concept of technology being unable to handle some input as an "allergy" for some reason makes me giggle.

I was recently an owner of a Merced-Benz commercial van, and the software was by far the worst part of that whole experience. It had obvious race-condition type bugs when it came to the user interface layer, but most frustrating was its tendency to succumb to some kind of memory leak on long drives where the entire head unit would just lock up and crash to a black screen after 6-7 hours of being turned on. Because th…

> if the system fails to detect any other vehicles for a period of more than about 90 minutes, it assumes that there is a sensor fault, and refuses to operate I have a current model Sprinter and this behavior is frustrating (thanks for the explanation, by the way, I thought it was a random bug). Cruise will also disengage in heavy rain or snow, with the system saying the sensor is dirty. It wouldn’t be so bad if trad…

You know you can also download Offline maps. One of Google Maps best features.

The 90s was a sweet spot for the three luxury German brands: Audi, BMW and Mercedes Benz. Mercedes in particular has had a very marked decline in quality since then.

Like what’s the highest quality luxury brand now, Lexus? Given that it’s Toyota engineering behind it I’d assume they are still good but I’ve never been in that market so idk.

Still those three, plus Lexus, Infiniti, Acura, Range Rover etc.
