Autonomous Driving Lane Selection With Variable Execution Intervals

The patent applies parameter changes by varying the execution intervals of lane selection determination processing among different autonomous vehicles. Instead of using fixed intervals for all vehicles, the system assigns different time intervals (e.g., Vehicle A: 2 seconds, Vehicle B: 3 seconds, Vehicle C: 2.5 seconds) to each vehicle's lane change decision processing. This parameter variation ensures that even when multiple vehicles detect the same empty space situation, they will execute lane changes at different times, preventing simultaneous lane changes and hunting behavior while maintaining predictable and consistent decision-making processes.

The patent applies periodic action by implementing regular, scheduled lane selection determination processing at fixed time intervals for each vehicle. Instead of continuously monitoring and immediately responding to every change in empty space situation, the system performs lane change decisions at predetermined periodic intervals (e.g., every 2-3 seconds). This periodic approach maintains traffic flow efficiency by regularly updating lane selections while providing occupant comfort through predictable, non-sudden lane change timing that feels natural and expected.

The patent applies asymmetry by introducing asymmetric variations in the execution intervals of lane selection determination processing among different vehicles. While all vehicles use the same lane selection algorithm (maintaining system uniformity and adaptability), each vehicle executes the algorithm at different time intervals (e.g., Vehicle 1: 2s, Vehicle 2: 3s, Vehicle 3: 2.5s). This asymmetric timing variation breaks the symmetry of simultaneous decision-making, ensuring that even identical algorithms produce staggered lane change decisions that prevent harmful simultaneous lane changes while preserving the benefits of uniform system behavior.
