1. A method for operating a motor vehicle in the event of an unavoidable collision with a collision object comprising:
determining environment data relating to the collision object, by an environment sensor device comprising at least one environment sensor;
evaluating the environment data to determine at least one driving intervention information for collision consequence reduction; and
automatically guiding the motor vehicle in accordance with the driving intervention information;
wherein evaluation of the environment data is carried out together with structural information of the motor vehicle describing structure of the motor vehicle, the structural information further comprising elements absorbing collision energy of the motor vehicle;
wherein the evaluation of the environment data is carried out in such a way that, when the driving intervention information is determined, a changed collision point maximizing the deformation energy absorbed by the vehicle structure and to be produced by the driving intervention information is determined;
wherein determination of the deformation energy from a deformation path is carried out in an energy grid method; and
wherein, when determining the changed collision point, in addition to maximizing the deformation energy, one or both of a penetration depth of the collision object into the motor vehicle is minimized and a maximum permissible penetration depth of the collision object into the motor vehicle is determined.
