2.1 Item definition

The item comprises a complete ASIL B safety-related system consisting of three primary functional elements: sensor subsystem, processing subsystem, and actuation subsystem. This architecture represents a generic safety function implementation applicable to various automotive applications requiring ASIL B integrity level. ASIL B compliance for a specific system depends on the design of the whole system.
