A method is provided for determining a maximum speed limit for a reversing vehicle combination that includes a towing vehicle and at least one towed trailer. The method includes determining a maneuver that is to be performed by the vehicle combination, simulating the complete maneuver in advance by using a control algorithm and a state space model, thereby obtaining the steering behavior of the vehicle combination during the maneuver, and calculating the maximum speed limit for the vehicle combination during the maneuver by using at least one predefined limiting condition. A maximum speed limit for a reverse assistance function can be estimated in advance, which allows for a faster and more efficient reversing of the vehicle combination, and at the same time allows for an improved comfort for the driver.
