Abstract: A dual-electrode occupant (12) detection system (10) configured to determine an occupant (12) presence on a seat assembly (32). The system (10) includes two electrodes (20, 28) that each generates an electric field in response to an applied excitation signal (50). The two electrode signals arising therefrom can be measured individually and/or combined to detect more reliably an occupant (12). Such a configuration advantageously avoids the added expense and complication of an electrode arrangement that relies on an underlying shield layer to reduce electrode signal (24) degradation caused by a seat heater element.

Abstract: Image processing parameters of an imaging chip (20b) in a vision-based occupant sensing system (VS) are adjusted for each frame based on ambient illumination responsive information obtained in the idle period preceding that frame (36, 42). The same sensing data is also used to determine if active illumination is needed to supplement existent ambient illumination during the ensuing image acquisition interval (38). The inter-frame ambient illumination is detected with an external light sensor (24) or with selected pixels of the imaging chip (20b), and the information is used to calculate and set the gain and integration time (42) of the imaging chip (20b). In applications where the resolution of the imaging chip (20b) significantly exceeds the resolution required for occupant sensing, intensity data from one or more otherwise inactive pixels (28) is averaged with the intensity data from the normally active pixels (26) to adapt the sensitivity of the imaging chip (20b) to changing ambient illumination.

Abstract: An occupant sensor mat (40) configured to be located proximate to a seating surface (34) of a vehicle seat assembly (12). The mat (40) includes a sensor electrode (24) formed of conductive material and configured to radiate an electric field (25) in response to an excitation signal (26) for determining an occupant (16) presence proximate to the seating surface (34). A heater element (28) is configured to underlie the sensor electrode (24). The heater element (28) is formed of conductive material and configured to radiate heat in response to electrical current for warming an occupant (16) residing on the seating surface (34). An incompressible spacer (46) is interposed between the sensor electrode (24) and the heater element (28). The incompressible spacer (46) formed of a material sufficiently flexible for locating proximate to a seating surface (34), and sufficiently incompressible to prevent a substantial change in capacitive coupling between the sensor electrode (24) and the heater element (28) from before to while an occupant (16) resides on the seating surface (34).

Abstract: A seat belt reminder system (10) includes an occupant sensor (12) to detect an occupant (14) in a seat (18) of a vehicle (20) and a buckle sensor (22) to detect when a seat belt (28) is latched to a seat belt buckle (24). A controller (40) detects whether the seat belt buckle (24) is latched and a wireless transmitter (42) sends the buckle status to a remote receiver (30) in the vehicle (20). The controller (40) and transmitter (42) are powered by a battery (44) that is separate from the vehicle electrical system (32). The controller (40), transmitter (42), and battery (44) may be incorporated into the occupant sensor (12). A separate power supply for the controller (40) and transmitter (42) and a wireless connection to the receiver (30) in the vehicle (20) eliminates the need for a wiring harness from the seat (18) to the vehicle (20). The seat belt reminder system (10) may provide long battery life by connecting the controller (40) and transmitter (42) to the battery (44) only when the seat is occupied.
