OS IN CARS

[Yash.]

*NOOB ALERT*

What are the operating systems used in cars?

Can somebody pls name as many of them as possible

 

Does anybody have experience using different kinds of them what are the roughedges they currently have over something like a tesla also why are they better than tesla's os 

 

Are they visually distinguishable ?

Coz i suppose all manufacturers use different skins for different cars and stuff..

 

i know and have virtually seen a couple of them like android automotive, there is also a automotive grade linux 

 

*Speculative but....*

Will andorid automotive be the os on the other side of teslas os like andorid is on the other side of ios?

 

are they cross compatible with different hardware infrastructure they prolly wouldnt be coz that doesn't happen on pcs to like arm and x86 have to have different os' even if they are superficially the same

 

What kind of embedded systems do current cars use?

 

Arm realsed a auto focused system, 

Hyundai announced a partnership with nvidia 

Volkswagen has set out to make its software but if internet articles are anything to go by they are struggling

 

I suppose unlike a desktop os an os in a car might also need to continually update info from sensors am i correct or are there different sytems who manage that

 

Also do these os also support the mobile apps that certain companies have to go with their cars or is that a different thing

i think most os's are proprietary cuz they perform very basic functions like changing the radio station, or popping up a map from google maps

theyre probably cross compatible but i dont see a reason for anyone to attempt such a modification cuz theres nothing to gain out of it

lastly,in new cars where steering,brakes and acceleration are controlled to the computer(for stuff like object avoidance or automatic parking) those systems probably have no connection to the outside world and run seperate from the infotainment system for because of the security risks associated with wiring it to the outside world

 

(all of this could be wrong btw)

QNX was widely used, now I think Android has taken over.

 

No personal experience, I like my cars with manual transmissions and Weber carbs. (in other words, old)

There was a car review from a while back and the car was running on Windows. It even had a Windows sticker around the center cup holder.

Depending on when it was it could have been Windows CE. I have an old GPS from the mid 2000s that runs Windows CE.

Windows CE may be the OS it was running on because that review is from a long time ago.

There isn't a single OS on the vehicle and everything is encapsulated through modules that have a specific task. The infotainment has an OS which on newer vehicles is usually a custom version of android. But besides that there's no OS at all or a customized and/or proprietary RTOS (real time operating system) on any of the other modules. Everything is linked together in some manner using a variety of data buses (mostly CANbus with LINbus being used for sub modules). The vast majority of the modules and sensors routed through the BCM (body control module). So your ambient air temperature sensor is typically wired through your BCM and then your infotainment will poll your BCM asking for the outside temperature to display on the system. Newer vehicles will have over 100 different modules each of which is responsible for single task. Even your window switches in newer vehicles are a module that sends a signal to your BCM to engage power to the window motor. Backup camera's and similar are usually routed through to an HMI module then to the BCM (IIRC) and then to the Infotainment (My credentials for GM's GMSi and TIS2Web, Alldata, and Ford motorcraft have all expired so I can't pull up the information.).

 

Basically the Infotainment has nothing to do with the rest of the car. It will request data from other modules but beyond that all it does is play music. It has an OS to make it easier for people to interact with it but the other modules have no such requirement.

Windows CE

There was a brief period in time where Microsoft was attempting to make the next Gen (and this was some time ago, mind you) be-all-end-all embedded OS for cars, GPS, gaming consoles, etc.

It was supposed to have the footprint of Windows CE

The user friendliness of Windows ME

and the stability of Windows NT

and it was going to bind everything together where you only needed 1 OS.

 

It was called Windows CEMENT

"Windows update will restart your car in …24 seconds, please drive to the right side to stop and leave the car safely…"

For the past 5-6 years, the OS on most cars is either QNX or Android as mentioned by @Radium_Angel. Please note that these OSs are highly modified.

 

Honda uses Android

Toyota uses QNX

Some car manufacturers like Mercedes, does a lot of effort to hide the underlying OS and sold as in a in-house OS. Probably uses QNX, just highly modified.

 

That said, Tesla is powered by a custom Linux distro.

 

If your car has Android based OS, no you don't have Google Play store, and your are blocked from install side loading apps. This is for liability reasons. You should be focused on driving not watching videos or movies while driving, let alone text message. 

 

Windows used to exist in cars, in 2014, but this has been long gone. It's not Windows CE, but one for cars. It flopped. Similarly to Windows Phone, the biggest issue is the lack of customization interface that manufacturers wants to differentiate their product from other models that they sell, and competitors. OS name was Windows Embedded Automotive

 

Android Auto and Apple Car play support. You have license deals and you have exclusivity deals that occurs. For example, Toyota Corolla in Canada and US, specifically the 4 door model, is Apple Carplay only. The hatchback version, despite identical infotainment, same version, identical interior, has both.
