摘要： A capacitance measuring system detecting an occupant of a vehicle. A sensor/heater assembly is arranged in at least one of a seat or a steering wheel of a vehicle and includes a sensor and a heater arranged adjacent to the sensor. A measurement circuit is configured to output an excitation signal to the measurement circuit and the sensor/heater assembly, measure a resonant frequency of the measurement circuit and the sensor/heater assembly in response to the excitation signal; determine at least one capacitance value based on the resonant frequency; and determine whether a body part is in proximity to the sensor based on the at least one capacitance value.
