Method for actuating restraint means for a vehicle, computer program, electronic storage medium, and device for actuating restraint means for a vehicle

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;
• actuating 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;
• determining a first value that is representative of an first instantaneous deformation depth of a deformation zone of the vehicle at a first instant as a function of the ascertained value that is representative of the force acting on the vehicle;
• wherein in the actuating step, the restraint device are also actuated as a function of the determined first value that is representative of the first instantaneous deformation depth;
• wherein at least one second value that is representative of the acceleration is detected at a second instant, and a second value that is representative of the force acting on the vehicle as a function of the at least one second value that is representative of the acceleration is ascertained, and a second value that is representative of a second instantaneous deformation depth of the deformation zone of the vehicle as a function of the ascertained second value that is representative of the force acting on the vehicle is determined, and the method further comprising:
• ascertaining a rate of deformation of the vehicle as a function of the first instant and the determined first value that is representative of the first instantaneous deformation depth, and as a function of the second instant and the ascertained second value that is representative of the second instantaneous deformation depth;
• wherein the restraint device is also actuated as a function of the ascertained rate of deformation, the second instant following the first instant, and the second instant following the first instant in a following computing cycle.
