SCS in Autonomous Systems
FSG24 Tech Inspection Workshop If an AS is implemented, all its signals must be monitored accordingly (T 11.9 + T 14.5.1)
FSG25 AS Beginner’s Guide The ASB signals and other signals of the Autonomous System are considered to be System Critical Signals (SCSs), see T 11.9.1, and therefore require some additional measures to be taken that are also discussed in this document.
Checking SCS for AS
USB connection is used between ECU and ACU
T 11.9.2
- (c) Failures of sensor signals used in programmable devices:
- Implausibility due to out of range signals, e.g. mechanically impossible angle of an angle sensor.
- (d) Failures of digitally transmitted signals by cable or wireless:
- Data corruption (e.g. checked by a checksum)
- Loss and delay of messages (e.g. checked by transmission time outs)
