Forward Collision Warning and Automatic Emergency Braking XIL Simulation Procedure and Minimum Performance Requirements - Truck and Bus

2024-03-25
WIP
J3319
This SAE Recommended Practice (RP) establishes uniform vehicle level simulation procedure for Forward Collision Avoidance and Mitigation (FCAM) systems (also identified as Automatic Emergency Braking (AEB) systems) used in highway commercial vehicles and coaches greater than 4535 Kg (10,000 lb.) GVWR. For Hardware-in-the-loop implementation of the recommended practice, the ESC system will be part of the test. This RP does not apply to trailers, dollies, etc. and does not intend to exclude any particular system or sensor technology. These FCAM systems utilize various methodologies to identify, track and communicate data to the operator and vehicle systems to warn, intervene and/or mitigate in the longitudinal control of the vehicle.
