In this study, a physical informed neural network is developed to perform an accurate tire-road friction estimation by utilizing those advanced vehicle sensors. A runway friction tester is employed as the ground truth. More than 15,000 GPS date points and other vehicle dynamic data points are collected during the field experiment, as a result, short convergence time and desired prediction accuracy are achieved by introducing the magic tire model and the slip-slop factor into the loss function.en-USAttribution 4.0 InternationalAutonomous VehicleVehicle-based sensingPavement sensingreport
