چکیده مقاله
This study developed and evaluated a lightweight Pedestrian AEB/FCW controller in a CarSim 2024 Simulink closed loop environment using a Euro NCAP style CPNA 25 test sequence The implemented logic combined i bumper referenced target geometry and an in path corridor gate, ii path aligned TTC and a required deceleration based risk measure, and iii hysteresis/persistence with a rate limited, graded brake pressure request The resulting behavior produced smooth pressure build up when risk increased and invoked maximum braking only under hard conditions Across the executed sequence, the results indicate that collision avoidance was achieved in the majority of instances, with one isolated collision observed The failure case occurred at a very late encounter state TTC on the order of 0 45 s with non negligible closing speed , implying insufficient remaining time/distance for the controller given its gating and pressure dynamics to fully prevent contact Overall, the findings suggest that the proposed risk based structure can provide effective mitigation with limited computational complexity, while the remaining failure mode points to a clear tuning trade off: improved robustness in the most demanding cases is likely to require earlier triggering and/or increased initial braking authority e g , higher minimum mitigation pressure or reduced pressure rate limiting without materially increasing nuisance activation
