Autoware Hazard Lights Selector
Purpose
The Hazard Lights Selector is a node that manages and selects hazard light commands from multiple sources (planning and system) to determine the final hazard lights state of the vehicle.
Inner-workings / Algorithms
The node operates on a timer-based update cycle and implements the following logic:
- Receives hazard light commands from both planning and system sources
- If either source requests hazard lights to be enabled, the final command will be to enable hazard lights
- If neither source requests hazard lights to be enabled, the final command will be to disable hazard lights
- The selected command is published at a configurable update rate
