OS IN CARS
OS IN CARS
The operating systems in vehicles vary widely. Many manufacturers employ distinct interfaces for each model, such as Android Auto and automotive-grade Linux. These systems are often visually different from one another, though they may share similar skins across brands. There’s some speculation that Android Auto might become the standard on newer Tesla models, but it’s unclear if this will happen. Regarding compatibility, these OSes generally support mobile apps, though integration can differ. Embedded systems in current cars typically use ARM processors, while Hyundai has partnered with NVIDIA and Volkswagen is developing its own software. It seems hardware requirements might differ compared to PCs, especially between ARM and x86 architectures.
I believe most operating systems are designed as closed platforms since they handle very simple tasks like switching radio stations or displaying maps from Google Maps. They might seem cross-compatible, but there’s little incentive for developers to modify them. In modern vehicles, steering, braking, and acceleration are managed by computers for functions such as obstacle avoidance or automatic parking. These systems likely operate independently from the infotainment system due to security concerns about connecting to external networks. This perspective might be incorrect, though.
QNX was commonly utilized, but it seems Android is now dominant. This is just a perspective—I prefer vehicles with manual gear shifts and Weber fuel injection, which are classic options.
Windows CE could be the operating system in use since this review dates back a while.
The vehicle runs multiple operating systems, each tailored for specific functions. The infotainment system typically uses a custom Android variant, while most other components run either standard or proprietary real-time operating systems. These parts connect via various data pathways, mainly CANbus and LINbus for smaller units. Most modules and sensors pass through the BCM (body control module), which handles things like ambient temperature readings. The BCM communicates with the infotainment to show external temperatures. In newer models, there are over 100 distinct modules, each managing a single task. Even window controls act as modules that signal the BCM to power the window motor. Backup cameras and similar features usually go through an HMI module before reaching the BCM. The infotainment system mainly focuses on media playback and user interaction, relying on its own OS for ease of use, while other modules operate independently without needing such support.
Microsoft tried to create a unified operating system for cars, GPS, gaming devices, etc., around the time it was still relevant. It aimed to combine the ease of Windows ME with the reliability of Windows NT, all in one platform. This project was known as Windows CE.
The Windows update may cause your vehicle to restart after approximately 24 seconds. Please move to the right side to safely stop and disconnect the car.
Over the last few years, most vehicles run on QNX or Android systems, as noted by @Radium_Angel. These operating systems are significantly customized. Honda employs Android, Toyota relies on QNX, while some brands like Mercedes invest heavily in concealing their core OS and present it as proprietary. Likely, they use a modified version of QNX. Tesla runs its own Linux distribution. If your car uses an Android-based system, you won’t find the Google Play store, and installing third-party apps will be restricted for safety reasons. Keep your attention on driving rather than scrolling or chatting while on the road. Windows was once available in cars, but it’s no longer common now—it was a different platform altogether. The situation is comparable to Windows Phone, mainly due to limited customization options that manufacturers prefer to maintain uniqueness. Available OS names include Windows Embedded Automotive, Android Auto, and Apple CarPlay support. You may have licensing agreements and exclusivity arrangements, such as the Corolla models in Canada and the US where Apple CarPlay is the sole option, while the hatchback version offers both systems despite identical features.
