1. A method for predicting the expected travel path of a moving vehicle by numerical integration of a dynamic vehicle model using at least one rotational travel state, which is affected by the angular motion of the vehicle, and at least one longitudinal travel state, which is affected by the linear motion of the vehicle, the method comprising:

  • determining time-related function rules for a predicted rotational travel state and/or for a predicted longitudinal travel state; and

    prediction values for the travel state concerned at specific points in time by numerical integration using said function rule,wherein the time-related function rule of a predicted travel state is determined by;

    obtaining respective rotational longitudinalinput variables for at least two time-derivatives of the travel state concerned from measured values, andrelating the input variables in linear dynamic models of order equal to the number of input variables of the travel state concerned using specified time constants, by determining from the linear model a time-related function rule for prediction values for the input variable concerned, and by analytically integrating the function rule for the prediction values of the input variable.
