Abstract

The application discloses a method for confirming parameters of a longitudinal control model, a vehicle control method, a storage medium, and electronic equipment, which include obtaining state characteristics of road test data; clustering the state characteristics to divide control intervals; determining the state characteristics of each control interval time-distance model; calculate the overall fitting acceleration deviation of all control intervals according to the time-distance model; use the model parameters of the time-distance model of each control interval corresponding to the overall fitting acceleration deviation meeting the predetermined conditions as the longitudinal control model parameters. Utilizing this application can not only reduce the interference of subjective factors, increase the objectivity of the division of control intervals and the determination of longitudinal control model parameters, but also save time, improve efficiency, and reduce costs, and can also make the setting of longitudinal control model parameters easier. It conforms to the actual driving, and then makes the control of the automatic driving system closer to the driver's driving habits, improves the smoothness of logical switching of each control interval, and improves the experience effect of automatic driving.

Description

technical field [0001] The present application relates to the technical field of automobiles, in particular to a method for confirming parameters of a longitudinal control model, a vehicle control method, a storage medium and electronic equipment. Background technique [0002] The ACC (Adaptive Cruise Control, intelligent cruise control system) system can not only maintain the speed set by the driver, but also reduce the speed of the vehicle at any time under specific driving conditions, and even automatically brake to adapt to traffic conditions. At present, the existing ACC system divides the control modes according to human experience, and then confirms the corresponding model parameters under each control mode. The subjective factors are relatively large, and it is impossible to objectively divide the control modes and determine the model parameters, and the manual division takes a long time. Low efficiency and high cost. Contents of the invention [0003] In view of ...
