Attribute Value
id com.example.stig.clusters.aeb.requirements.aebRequirements.reportPerceptionDegradation
name Report perception degradation
description Automated emergency braking shall set Cluster function-status output to degraded and keep Cluster brake-request output inactive within 100 ms if fewer than two forward sensors are available or the newest sensor observation is older than 100 ms.
