Seat occupancy detection system
First Claim
1. Seat occupancy detection system for a vehicle, comprising a first seat antenna electrode arranged in a seat of a vehicle;
- a first floor antenna electrode arranged in a foot area associated with said seat;
at least one additional floor sensor arranged in said foot area; and
a driver and evaluation circuit operatively connected to said first seat antenna electrode, said first floor antenna electrode and said at least one additional floor sensor, wherein said driver and evaluation circuit includes means for determining capacitive coupling of said first seat and said first floor antenna electrodes with an object, and wherein said first floor antenna electrode and said additional floor sensor are individually operable by said driver and evaluation circuit.
