Approach for a Safety Element Out of Context for an Active Wheel Speed Sensor Circuit Module

Several modules in automotive are usually modified and adapted for various project-specific applications. Due to a standardized safety concept a high reusability is accessible. A safety element out of context (SEooC) according to ISO 26262 can be a suitable approach. Based on the same safety concept and analysis, common modules can reach high reusability. For developing according to a module out of context, an appropriate and detailed development approach is required. This is not provided circumstantial in the safety standard. This paper shows how to deduce this development processes for platform modules. Therefore, the detailed approach of the Safety Element out of context is derived. The aim is to create a detailed workflow for all phases of the development and integration of any kind of system modules. As an application example, an automotive project for an active wheel speed sensor circuit module is considered.
