Abstract
In view of the severe weather conditions in cold regions, the basic characteristics and braking distance of ice snow covered pavement are analyzed. This paper uses the PreScan/CarSim/Simulink software co-simulation method to test the automatic emergency braking (AEB) system on ice-snow roads. Through the appropriate adjustment of the time to collision (TTC) threshold, the car makes automatic emergency braking on the road with low friction coefficient system can achieve the effect of collision avoidance and injury reduction.
Highlights
This article mainly focuses on the road scenes under special severe weather conditions in cold areas to carry out test research
When a car is driving on an ice-snow road, the ice and snow on the road reduces the friction coefficient between the tire and the road to a certain extent, which is prone to cause traffic accidents
According to the analysis of the simulation results, the braking distance calculated by the formula is basically the same as the braking distance obtained by CarSim simulation
Summary
The annual average temperature is 0°C~11°C, and the freezing and snowfall weather below 0°C accounts for 42.6% of the whole year [1]. The application of automatic emergency braking (AEB) system for automobiles is becoming more and more mature, there are relatively few test researches involving ice-snow road scenes. This article mainly focuses on the road scenes under special severe weather conditions in cold areas to carry out test research
