Different techniques to deal with gamma rays and other scenarios: every variable is stored in two places, the second is the complement value; plausability tests, can the value jump from 10 to 1000 in 10ms? and so on.

- bob1029 4y agoAnd if something directly impacts the mosfet gate drivers, what then? Is there some sort of N+1 strategy all the way up to the mechanical steering linkage?
- GoToRO 4y agoYes. Every system is evaluated from a safety perspective and measures are taken. What's interesting is that N+1 redundancy is seldom used. Usualy there is a totaly different system that checks the main system. Like a software watchdog that checks a hardware one. This is also why they need 5 years to get out a model that is more or less the previous model. That and they really don't get software.
