Fail operational systems are the main challenge of future E/E and ECU architectures to comply with safety requirements in automated cars.
An alternative approach for a fail operational architecture in automotive systems is the 2-out-of-2 Diagnostic Fail Safe (2oo2DFS) architecture realized by two 1-out-of-1 (1oo1) channels with diagnostics (1oo1D).
A higher level of integration for fail operational consists on the implementation of the redundant sub-systems inside one ECU.
Rather than redundancy, where parts are duplicated so new ones can take over for failed ones, fail operational ability means that even if components in the system fail, the engine will continue to operate.
At the very least, providing fail operational behavior requires even more redundancy (more than one monitor/actuator pair), and very likely design diversity so that common-mode software design failures do not cause a systemic failure.
Fail operational system design has been done successfully in aerospace and other contexts for decades, but is still difficult for several reasons.
