Claim 0:
1. A method for generating a dynamic speed profile of a motor vehicle for simulating vehicle operation on a test bench and/or on a test computer in a model-based manner, the method comprising:
determining a route-based static speed profile for a route resolved into route segments based on information from a digital map, wherein speeds of the route-based static speed profile correspond to respective maximum speed values granted by a driver or by a legal speed limit;
determining a route-based dynamized speed profile on the basis of the route-based static speed profile, wherein the route-based dynamized speed profile factors in a defined target deceleration to reach speed minima of the route-based static speed profile;
determining the dynamic speed profile, resolved into time increments, on the basis of the route-based dynamized speed profile, wherein a speed of the dynamic speed profile is calculated time increment by time increment from a starting point of the route from an applied acceleration determined in each preceding time increment, wherein the applied acceleration is determined based on a speed dictated by the route-based dynamized speed profile in a route segment corresponding to the respective preceding time increment and an applied speed in the respective preceding time increment; and
controlling the speed of the motor vehicle during the simulated vehicle operation on the test bench and/or on the test computer in the model-based manner based on the dynamic speed profile,
wherein the amount of an acceleration value difference in one time increment of the time increments to an acceleration value in a preceding time increment of the time increments is less than a threshold value, wherein the threshold value is determined as a function of the driving physics, the motor vehicle, and/or a driver.
