1. A method for predicting movement trajectories of a vehicle for one of preventing a collision and reducing crash severity, comprising:

  • predicting all movement trajectories of the vehicle for which forces occurring at wheels of the vehicle are, at each instance of each of the trajectories, a maximum force capable of being transferred from the wheels to a road without the wheels losing adhesion to the road, the maximum force capable of being transferred from the wheels to the road being substantially equal to μ

    max*Fn, μ

    max being a coefficient of friction between a roadway and a tire of the wheels of the vehicle, Fn being a vertical force applied by the vehicle to the roadway, the movement trajectories having a combination of steering actuation and brake actuation;

    determining μ

    max in accordance with signals from at least one of an anti-lock device and an electronic stability program;

    detecting an object by a surroundings sensor system, the surroundings sensor system including at least one of a radar sensor, a lidar sensor and a video sensor; and

    wherein the determining μ

    max includes evaluating additional signals from a rain sensor.
