California-based Drako Tech has announced DriveOS with HyperSafety, an automotive operating system designed for single-Electronic Control Unit (ECU) operation. The platform consolidates vehicle subsystems, including control systems, ADAS and digital cockpit, into one unit to reduce costs and enable over-the-air (OTA) updates.
Launched in 2015 and utilised in Drako GTE and Drako Dragon vehicles, DriveOS supports internal combustion, electric and hybrid propulsion systems.
The HyperSafety system provides real-time performance via a single-ECU architecture. According to Drako Tech, the networking backbone facilitates communication four times faster than multi-ECU Time-Sensitive Networking (TSN) automotive Ethernet.
The architecture employs hardware isolation and redundancy to maintain operation during component failures. By using a reduced code footprint and hardware partitioning, the platform aims to limit attack surfaces for cyber security and streamline validation processes.
Industry Integration
Drako Tech provides development environments that run natively on DriveOS:
- Control Systems: Allows engineers to build vehicle controls from Simulink models.
- Digital Cockpit: A system for instrument clusters, navigation and multimedia.
- ADAS: A software foundation for driver assistance with low-latency control.
The platform addresses the complexity of multi-ECU architectures, which typically require separate units for functions such as seats, doors and thermal management. Drako Tech uses a separation kernel to run safety-critical systems alongside non-critical systems, such as infotainment, on the same ECU.
DriveOS introduces hard real-time capabilities to Linux without requiring kernel changes. This allows developers to use Linux libraries and tools for safety-critical systems.
Key features include:
- Performance: 108-microsecond end-to-end performance compared to 514 microseconds for TSN Ethernet.
- Consolidation: The ability to move functions onto a single PC architecture to reduce hardware mass and complexity.
- Redundancy: Hardware-backed isolation ensures faults in one subsystem do not affect driving functions.
- Cloud Integration: Real-time fleet management and diagnostics without creating access paths to control systems.
Dean Drako, CEO, Drako Tech, said, “Nearly half of the cost of new vehicles is tied up in software and electronics. Drako Tech now offers all OEMs worldwide – regardless of size or influence – a definitive leap in their ability to deliver exceptionally safe, connected, AI-enhanced vehicles, with massive cost advantages. We are the first to achieve the ultimate goal – a single-ECU, hard real-time operating system and unified electronics architecture with mixed criticality – while providing OEMs a flexible deployment path.”
