Abstract: A method for simulating a collision situation between two vehicles for testing a driver assistance system in a driving simulator or in a Vehicle-in-the-Loop scenario. A fellow vehicle simulated on a simulation computer is assigned a trajectory that passes through a point of collision of a planned collision between the fellow vehicle and an ego vehicle that is not controlled by the simulation computer. The driver assistance system is equipped to exchange data with the simulated environment in real time and to influence the driving behavior of the ego vehicle in a collision situation. A target distance to the point of collision is determined for the fellow vehicle that the fellow vehicle would have to have in order to arrive at the point of collision simultaneously or substantially simultaneously with the ego vehicle, under the assumption that it travels at the specified arrival speed.
