1. A method for actuating a restraint device for a vehicle, the method comprising:
- detecting, at a first instant, at least one first value that is representative of an acceleration,ascertaining a value that is representative of a force acting on the vehicle from the detected at least one first value that is representative of the acceleration, andactuating the restraint device as a function of at least one of the ascertained value that is representative of the force acting on the vehicle, and a value derived from the ascertained value that is representative of the force acting on the vehicle,wherein in the step of ascertaining, the ascertained value that is representative of the force acting on the vehicle is ascertained as a function of predefined, at least one of vehicle-specific parameters and installation-specific parameters, the at least one of the vehicle-specific parameters and installation-specific parameters describing influences of a structure of the vehicle on a propagation of an acceleration signal generated by the force acting on the vehicle, the structure of the vehicle including a crash deformation structure of the vehicle.
