Dr Sebastian Ohl, Senior Manager, Elektrobit

Next-generation vehicles with independent processing blocks allow the easy re-use of cause-effect chains. However, given this functionality is no longer bound to an electronic control unit (ECU), placing processing blocks on ECUs becomes increasingly challenging.

Using the Logical Execution Time (LET) paradigm, Elektrobit’s Dr Sebastian Ohl showcases a solution using a high-performance ADAS system and a safety ECU running AUTOSAR Adaptive and Classic.

Key topics and takeaways:

  • The LET-paradigm provides an effective implementation of cause-effect chains
  • Cause-effect chains help define system behaviour independently of ECU deployment
  • Usage of LET can be achieved with EB’s infrastructure products with minimal changes
  • LET can support the transfer from single-core to multi-core ECU applications
  • Following the LET-paradigm eases scheduling changes on a system level
