OSxCAR

Revolutionizing Software-Defined Architectures

Design. Validate. Optimize. End to end.

OSxCAR combines portable vehicle software with a reconfigurable testbench, heterogeneous hardware and AI-driven network optimization. For reproducible tests and scalable SDV architectures.

Wasm-Components

Portable software modules for any target platform – compile once, run anywhere.

The hardware changes. The software stays.

OSxCAR develops an open platform that enables execution of the same software binary across CPU, GPU, and microcontroller — from testing to production.


One Binary for Every Target

From simulation to vehicle — on CPU, GPU, and microcontroller. Unchanged.

No recompilation. No adaptation. One software base for every target platform.

Software as a Product

Build once. Deploy everywhere.

Versioned, modular, with stable interfaces — integrable without vendor lock-in.

Speed & Efficiency

Minutes instead of months.

Test environments available instantly. Less effort, lower cost, faster results.

Safety & Compliance

What's tested runs in production.

Consistent execution across the entire lifecycle — for functional safety and cybersecurity.

Based on open standards such as WebAssembly and W3C.
Independent of hardware, operating system, and processor architecture — usable from vehicles to industries like robotics, avionics, and medical technology.

A new approach to vehicle software

Today

Software is adapted for each target platform.

With OSxCAR

One binary runs from simulation to vehicle — no porting, no recompilation.

  1. Simulation Model and validate functions
  2. Test Automated validation on virtual and real hardware
  3. Vehicle Identical binary in the control unit
  4. Cloud Same modules for updates and operations
What works in simulation works identically in the vehicle.

Technological foundation

WebAssembly

Enables hardware-independent execution on any processor — secure, fast, and portable.

→

W3C Standards

Define uniform interfaces for software components — vendor-neutral and interoperable.

→

AI Optimization

Intelligently places software modules on available hardware and optimizes network load automatically.

→

Testbench

Configures SDV test environments automatically — from individual components to full vehicle systems.

→
