Abstract: A device for predicting a future actual speed of a motor vehicle includes a low-pass filter, the low-pass filter being configured to filter a signal which is characteristic of a target speed of the motor vehicle and to provide this as a target speed of the motor vehicle; an acceleration governor, the acceleration governor being configured to predetermine a target acceleration for the motor vehicle in a time interval depending at least on the target speed of the motor vehicle; and a model, the model being configured to predict the future actual speed depending at least on the target acceleration.

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.
