Health Management System
A central health manager that watches ECU software and recovers from faults. I was the architect responsible for the health management design within the cockpit domain at a leading premium automotive OEM.
The case study
Technologies: health monitoring, software supervision, watchdog patterns, fault recovery, hypervised multi-OS platform, DLT
The challenge
Lots of software across several operating systems on one controller
Any process can hang, crash or miss its deadlines
If nobody notices, the customer does: frozen screens or missing features
Ad-hoc self-monitoring doesn't scale and leaves gaps
My approach
Centralised supervision: one health manager for all monitored components
Liveness and deadline checks on critical sequences
Escalating recovery: restart a process, a partition or the wider system
Health events fed into logging so faults are traced, not silently hidden
A single, consistent view of software health across the controller
Predictable recovery when something goes wrong
