1. A method for controlling a safety device of a vehicle, the safety device being configured to react to an imminent collision of the vehicle with a collision object by way of an intervention in a longitudinal and/or lateral guidance of the vehicle, the method comprising the following steps:
reading in: (i) from an interface to at least one environment sensor of the vehicle, environment data regarding a position of the collision object, and/or a velocity of the collision object, and/or an acceleration of the collision object, in an environment of the vehicle, (ii) from an interface to at least one trip data sensor of the vehicle, trip data regarding a position of the vehicle, and/or a velocity of the vehicle, and/or an acceleration of the vehicle, and (iii) from an interface to the safety device, intervention data regarding a planned intervention of the safety device;
ascertaining: (i) a first expected impingement point of the collision object on the vehicle using the environment data and the trip data, and (ii) a second expected impingement point of the collision object on the vehicle using the environment data, the trip data, and the intervention data;
executing an evaluation of a location of the first expected impingement point and of a location of the second expected impingement point relative to subregions referred to the vehicle, using reference data that define, for each subregion of the subregions, an evaluation factor that depends on an effect of a location of an expected impingement point in the subregion on a safety status of at least one occupant of the vehicle; and
generating, depending on a result of the evaluation, a control signal for output to an interface to the safety device, the control signal having at least one control parameter for controlling the safety device.
