Abstract

A wireless vehicular sensing system is disclosed. The wireless sensing system may include a radio frequency access control system including a plurality of antennas distributed within the vehicle (10) and at least one radio frequency transceiver (16) coupled to the plurality of antennas for effecting radio frequency interrogations of radio frequency access permission devices via the plurality of antennas in response to operator invoked interrogation requests, and a plurality of radio frequency sensors (11) distributed within the vehicle (10) and associated with systems other than vehicle access control. The at least one radio frequency transceiver (16) effects radio frequency interrogations of the plurality of radio frequency sensors (11) via the plurality of antennas in response to system invoked interrogation requests.
