Thermal and Electrical Stress Testing of Production Autonomous Compute Units
Subjecting the physical autonomous driving computer to -40°C to +85°C chamber temperatures while driving its power rails with voltage ripple perturbations.
NPU Thermal Throttling Characterization
Verifying that cooling degradation triggers orderly graceful degradation to Level 2 safety fallbacks rather than sudden catastrophic system reboot.
- Chamber temperature sweep from -40°C to +105°C under continuous load.
- 12V/48V power supply brownout and transient surge testing (ISO 7637-2).
- Coolant flow rate modulation simulating degraded radiator performance.
- Automated current consumption profiling across diverse neural networks.
