1. A method for controlling an occupant protection system of a vehicle, the method comprising:
- reading in, by a processing unit, (a) a vehicle acceleration value representing an acceleration of the vehicle and (b) a model parameter of an occupant model, the occupant model representing an occupant of the vehicle by at least two mass points, wherein the occupant model is a spring-mass-damper model representing motion of the occupant in a crash of the vehicle, and wherein the at least two mass points include a head mass point representing a head and/or a neck of the occupant and an upper body mass point representing an upper body of the occupant, the occupant model connecting the head mass point to the upper body mass point by a spring element;
determining, by the processing unit, at least one motion parameter relating to the mass points using the occupant model, the vehicle acceleration value, and the model parameter; and
producing, by the processing unit, a control signal for controlling the occupant protection system using the motion parameter.

Abstract
A method for controlling an occupant protection system of a vehicle includes reading in at least one vehicle acceleration value representing an acceleration of the vehicle and at least one model parameter of an occupant model by which a vehicle occupant is represented by at least two, in particular three, mass points. The vehicle acceleration value and the model parameter are processed in order to determine at least one motion parameter relating to the two, in particular three, mass points. Using the motion parameter, a control signal for controlling the occupant protection system is produced.

11. A system comprising:
- an input; and
processing circuitry interfacing with a vehicle occupant protection system, wherein the processing circuitry is configured to;
read in, via the input, (a) a vehicle acceleration value representing an acceleration of the vehicle and (b) a model parameter of an occupant model, the occupant model representing an occupant of the vehicle by at least two mass points, wherein the occupant model is a spring-mass-damper model representing motion of the occupant in a crash of the vehicle, and wherein the at least two mass points include a head mass point representing a head and/or a neck of the occupant and an upper body mass point representing an upper body of the occupant, the occupant model connecting the head mass point to the upper body mass point by a spring element;
determine at least one motion parameter relating to the mass points using the occupant mode, the vehicle acceleration value, and the model parameter; and
provide to the vehicle occupant protection system a control signal for controlling, the occupant protection system using the motion parameter. - View Dependent Claims (13, 14)

12. A non-transitory computer-readable medium on which are stored instructions that are executable by a processor and that, when executed by the processor, cause the processor to perform a method for controlling an occupant protection system of a vehicle, the method comprising:
- reading in (a) a vehicle acceleration value representing an acceleration of the vehicle and (b) a model parameter of an occupant model, the occupant model re resenting an occupant of the vehicle by at least two mass points, wherein the occupant model is a spring-mass-damper model representing motion of the occupant in a crash of the vehicle, and wherein the at least two mass points include a head mass point representing a head and/or a neck of the occupant and an upper body mass point representing an upper body of the occupant, the occupant model connecting the head mass point to the upper body mass point by a spring element;
determining at least one motion parameter relating to the mass points using the occupant model, the vehicle acceleration value and the model parameter; and
producing a control signal for controlling the occupant protection system using the motion parameter.
- reading in (a) a vehicle acceleration value representing an acceleration of the vehicle and (b) a model parameter of an occupant model, the occupant model re resenting an occupant of the vehicle by at least two mass points, wherein the occupant model is a spring-mass-damper model representing motion of the occupant in a crash of the vehicle, and wherein the at least two mass points include a head mass point representing a head and/or a neck of the occupant and an upper body mass point representing an upper body of the occupant, the occupant model connecting the head mass point to the upper body mass point by a spring element;
