Blocking Grid usage for Advance Driver Assist System (ADAS) Evaluations on Proving Ground

The problem was found during winter test of Adaptive Cruise Control (ACC) of Advance Drive Assist System (ADAS) on public roads. It’s coverage of ACC radar working surface by mixture of mud and snow that was “picked up” from road surface by other traffic participants. The result is radar is blind but ACC is still working. The test car can’t see obstacle in front and is can lead to serious collision. To study this situation the public road test method was developed. But this method is very sensitive to weather changes because of mud and snow mixture melts when temperature is above Celsius Degree. To avoid this problem the unified test method was developed. Accordance this method it’s possible to conduct comparison evaluation for different car models with ACC independently from season. Test preparation method was developed. Test equipment is fixed. Each car maneuver during the test is described. Other materials with mud and snow mixture performance was founded. Proving Ground tests will be conducted accordance this test method. The results will be published in separate article.
