Abstract:This report summarizes an evaluation of five NHTSA draft research test procedures designed to evaluate the test track performance of light vehicles equipped with advanced driver assistance systems (ADAS): active park assist (APA), intersection safety assist (ISA), blind spot intervention (BSI), traffic jam assist (TJA), and opposing traffic safety assist (OTSA). These draft research procedures were released on November 18, 2019, in Docket No. NHTSA-2019-0102. A 2017 Mercedes-Benz E300 was used as the subject vehicle for the APA tests, whereas a 2019 Audi A6 was used for the ISA, BSD, TJA, and OTSA evaluations. The tests defined within each draft research test procedure were found to be performable, and all test validity conditions specified within them were satisfied. That said, addition of a tolerance to specify permissible subject vehicle or principal other vehicle accelerations during ISA test conditions where the vehicle must be moved from rest is recommended, as no tolerance is provided in the September 2019 ISA draft research test procedure. Use of the ±0.05g principal other vehicle acceleration tolerance specified in the October 2019 TJA draft research test procedure is one option, as the range was used successfully during the lead vehicle decelerates, accelerates, then decelerates TJA trials described in this report.
