Study on Vehicle–Road Interaction for Autonomous Driving

Autonomous vehicles (AVs) are becoming increasingly popular, and this can potentially affect road performance. Road performance also influences driving comfort safety for AVs. In study, the influence of changes in traffic volume wheel track distribution caused by AVs on rutting distress asphalt pavement was investigated through finite element simulations. A vehicle-mounted three-dimensional laser profiler used to obtain roughness texture information. The vehicle vibration acceleration obtained dynamics simulations, skid resistance indexes 20 specimens were collected. results showed that an increase increasing AV accelerated occurrence distress; however, uniform at both ends transverse direction could prolong maintenance life flexible semi-rigid pavements 0.041 0.530 years, respectively. According Carsim Trucksim simulations multiple linear regression fitting, relationship models three factors, namely speed, roughness, comfort, high fitting accuracies; there some differences among models. Among indexes, arithmetic mean’s height (Ra) had greatest tire–road friction coefficient; Ra greatly influenced safe findings study present a speed control strategy based index ensuring during automatic driving.
