IntroductionWith the increase in vehicle electrification and autonomy, electronic control units are now subject to rigorous functional safety standards such as ISO 26262. Functional safety is defined by ISO 26262 as "the absence of unreasonable risk due to hazards caused by malfunctioning behavior of electrical and electronic systems." Malfunctions are broadly grouped into two categories: random faults and systematic faults.
Pi Innovo engaged with a large vehicle OEM to develop a custom ECU to be used on an autonomous vehicle demonstration fleet. All the OEM’s traditional suppliers refused to support the project due to the very aggressive timeframes. The ECU played a critical role in the overall vehicle positioning system and had to meet the following requirements:
- ISO 26262 ASIL-D
- Full redundant ASIL-D
- Fail-operational robustness to single-point failures (internal redundancy)
- Data transmission using 100BASE-T1... View More
