Abstract
A system for detecting an occupant in a vehicle seat that includes a sensing electrode located in a seat bottom of a vehicle seat. The system also includes a shield electrode located in the vehicle seat below the sensing electrode. A sensing circuit is operatively coupled to the sensing electrode and the shield electrode. A controller is operatively coupled to the sensing circuit, wherein the controller operates to configure the sensing circuit to apply current to the shield and sensing electrodes. The controller is configured to detect the presence of an object in the seat by comparing a measure of the quadrature component of the sensing current to a threshold wherein the measure is adjusted by an offset value that varies based on a value of a non-volatile counter.
