CAPACITIVE OCCUPANT SENSING SYSTEM AND METHOD |
摘要 |
An occupant detection system and method are provided for detecting an occupant seated in a vehicle seat. An electrode is arranged in a seat proximate to an expected location of an occupant for sensing an occupant proximate thereto. The electrode may be integrated with a seat heater. Control circuitry controls the seat heater. A signal generator is coupled to the electrode and configured output to the electrode a plurality of signals at a plurality of frequencies. Occupant detection circuitry detects voltages responsive to the plurality of signals at the plurality of frequencies and detects a state of occupancy based on the detected voltages. An LC circuit coupled to the electrode and the control circuitry suppresses capacitance generated by the control circuitry.
