Mud-Snow Layer Accumulation on Adaptive Cruise Control (ACC) System Radar and Thickness Measurement of It

Abstract

Some problem is appeared during ADAS Adaptive Cruise control (ACC) system evaluation on public roads during winter usage. During others ACC tests that were done before this problem was not considered. The essence of problem is working surface of ACC radar is covered by mud and snow mix layer. Mud and snow are picked up from road surface by other traffic participants. By this layer radar start to be "blind" and ACC either stop to work or continue to work but can’t see a vehicle or other obstacles in front. It’s possible to have serious collision if second one scenario is happened. The test method is developed for comparison test of vehicles with different radar location on public roads on winter condition. Test preparation algorithm was developed. There is description of measurement equipment that is necessary for the test. It was proved how many vehicles are necessary for the test and their relative location on road during movement. Mud – snow layer thickness measurement method was developed. It was described of responsibility of each test team member during the test. Test duration and test road choice were justified to collect enough date for further analyses. Practical test will be conducted based on this method. Results will be published in separate article.
