Longitudinal motion model calibration method, system and equipment for low-spacing start-stop vehicle and medium

The invention provides a method, a system, equipment and a medium for calibrating a longitudinal motion model of a low-spacing start-stop vehicle, and the method comprises the steps: dividing a vehicle driving scene in road traffic, and classifying the driving scene into a driving scene corresponding to a vehicle approaching region and a driving scene corresponding to a vehicle following region according to the longitudinal operation condition of the vehicle; the minimum parking distance of the vehicle is analyzed and determined according to measured data; on the basis of the vehicle minimum parking distance and a speed optimization model, scene driving track data sets of the approaching area and the following area are obtained; and calibrating a longitudinal motion model based on the trajectory data. According to the method, the corresponding vehicle low-distance parking and starting motion trail data are acquired by utilizing the speed optimization model on the basis of the measured data, the simulation sys
