Adapting a gain factor of an acceleration controller for a motor vehicle

Abstract

Methods and devices for adapting a gain factor of an acceleration controller for a motor vehicle are provided. An acceleration controller specifies an acceleration setpoint for the motor vehicle in a time increment. The acceleration setpoint is specified as a function a speed setpoint of the motor vehicle, an actual speed of the motor vehicle, and the gain factor. The device stores the speed setpoint, the actual speed, and the acceleration setpoint specified as information for at least two time increments, select a first subset of the information, and train a model as a function of the first subset. The model predicts an actual speed in a later time increment from at least one stored actual speed and at least one stored acceleration setpoint, select a second subset of the information, and adapt the gain factor as a function of the second subset, the model and the acceleration controller.
