A COMPUTER SYSTEM AND A METHOD FOR HANDLING A LIGHTING SYSTEM, AND A LIGHTING SYSTEM OF A VEHICLE

Patentradars sammanfattning

This patent from Volvo Truck Corporation covers a computer system with processing circuitry that manages a vehicle lighting system—particularly brake lights—composed of at least two redundant component groups, each with multiple light sources (LEDs) powered by separate power sources. The system continuously obtains diagnosis data comparing each group's status against a predeterminable safety model (e.g., ASIL-D compliance metrics such as minimum light intensity and activation response time). Upon detecting a fault or risk of fault in one component group, the processing circuitry reconfigures the lighting system to rely solely on the unaffected redundant group(s), enabling the vehicle to remain fail-operational. The invention targets autonomous and semi-autonomous heavy-duty vehicles, trucks, and buses requiring stringent functional safety standards.
