Sensor system and method for determining at least one of the weight and the position of a seat occupant
First Claim
1. A sensor system for determining at least one of the weight and the position of a seat occupant, comprising:
- a control unit;
at least two spaced measurement weight sensors;
wherein each measurement weight sensor provides measurement weight sensor signals; and
at least one virtual weight sensor providing virtual weight sensor signals, wherein a spatial data field is allocated to the seat and the sensor system, said spatial data field comprising sub-fields, and wherein calculation modes for virtual weight sensor signals depend on the sub-field in which a spatial center of measurement weight sensor signals falls;
wherein the at least one virtual weight sensor calculates the virtual weight sensor signals using the measurement weight sensor signals of at least one of the measurement weight sensors; and
wherein the sensor system calculates at least one of the weight and the position of the seat occupant using the measurement weight sensor signals and the virtual weight sensor signals.
