Abstract:The 13 test scenarios described in NHTSA’s August 2019 draft research active park assist (APA) test procedure were used to evaluate the system performance of three passenger cars: a 2017 BMW 540i, a 2017 Tesla Model S 90D, and a 2018 Cadillac CT6. This report discusses the test results and provides a general assessment of the scenarios used. The August 2019 version of this draft test procedure is an update to that was originally published in April 2018. The test scenarios were intended to emulate commonly encountered perpendicular and parallel parking scenarios. Two scenarios evaluated how the subject vehicle (SV) performed back-in parking maneuvers. Three scenarios tested the SV response to a pedestrian encroaching into the parking space while the vehicle performed the parking maneuver. Two scenarios examined the SV response to a following vehicle that stops and obstructs the SV path when it began to perform the parking maneuver. Finally, six scenarios were designed to see how the SV reacts to the driver performing a manual override of the steering, accelerator pedal, or brake pedal inputs as the SV performed the parking maneuver.
