A vehicle passenger sensing system and method in which the presence and position of a passenger is determined by transmitting an electric field (410 ) from a first electrode (30) and measuring currents induced by the electric field (420, 430) in a plurality of receiver electrodes (40, 50). The induced currents at the various receiver electrodes (40, 50) are then compared to determine the presence of an adult size passenger, to distinguish between a child in a front-facing child safety seat and a child in a rear-facing infan t seat, and to detect when a passenger is out of position. A switching circuit (620) is provided to selectively transmit the electric field from each of th e plurality of electrodes (511, 512, 516/517, 521, 522). |
