System – Consideration of Safety Criticality for Updates

A vehicle contains both safety and non-safety critical functions. Depending on the safety criticality of the affected function, the requirements for the update might differ. A failure in the vehicle infotainment introduced by a fault in a software update might lead to user frustration. On the other hand, a failure caused by an update to a safety critical component might lead to serious consequences and must be prevented.

“Safe and Secure Automotive Over-the-Air Updates – Operational and Functional Requirements”, (Sena, M., 2015).

Main Question

Are the safety criticiality aspects of the function to be updated considered for the update?

Alternative Questions:

  1. Is there a robust V&V procedure to ensure that sw updates of safety critical functions are sufficiently tested prior to release to avoid prevent potential new hazards due to the update sw?
