Safety distance detection of highway vehicles driving under partial water skiing conditions

Accurate safety distance detection under humid road conditions is of great research significance for improving driving safety. In this paper, a novel safety distance detection of highways vehicles driving under partial water skiing conditions is proposed. Firstly, the mechanism of tire water skiing and the model of water film thickness were analyzed. Secondly, the car following behavior of vehicles is analyzed, and the safety car distance model is established; By introducing sufficient distance coefficient K, the accuracy of the minimum safe driving distance calculation is improved. Finally, based on the CarSim2016 AEB system, combined with the minimum safe driving distance obtained from the solution, the safe distance detection of highways vehicles driving on is achieved. The experiment results show that the minimum safe distance of the proposed method are basically consistent with the actual critical driving distance, with a detection accuracy of 99.3%, a detection time of 0.3 seconds, and a variance of 0.01. This indicates that the proposed method can accurately detect the safe distance of driving vehicles and is more reliable.
