The world's smallest automotive real-time operating system

Automotive Real-Time Operating Systems (RTA-OSEK and RTA-OS)

Research from the Real-Time Systems research group at the University of York was exploited to design an exceptionally efficient Real-Time Operating System (RTOS), used in automotive Electronic Control Units (ECUs).

The RTOS has been standardised upon by many of the world’s leading automotive powertrain systems and chassis electronics suppliers, and is used in cars produced by nearly all of the world’s major car manufacturers. By 2015, the RTOS had been deployed in over 1 billion ECUs. This number is increasing at the quite astonishing rate of more than a quarter of a million ECUs per day.

  • Developed by the Real-Time Systems research group.
  • Researchers included Rob Davis, Ken Tindell, Neil Audsley, Alan Burns, and Andy Wellings.
  • Underpinning Research: Schedulability Analysis for fixed priority scheduling guaranteeing the timing behaviour of real-time embedded systems using a Real-Time Operating Systems (RTOS) and fixed priority scheduling.
  • Technology: Analysis tools and the exceptionally small and efficient RTA-OSEK and RTA-OS operating systems.
  • Impact: The RTOS has been standardised upon by many of the world’s leading automotive powertrain systems and chassis electronics suppliers, and is used in cars produced by a wide range of major car manufacturers world-wide. The RTOS has been deployed in over one billion ECUs (Electronic Control Units).
  • Commercialisation of the research: The RTA-OSEK operating system was initially developed by start-up company LiveDevices, which was subsequently bought by ETAS (part of Robert Bosch).
