Abstract
A universal, compartment-wide system identifies the presence and position of occupants of a multi-place vehicle by utilizing the occupants to conduct and radiate place-specific radio frequency signals that are received at various locations in the passenger compartment. The place-specific radio frequency signals are developed by low power transmitters disposed in the various seat/place locations, and a receiver disposed at a central location that is remote from the transmitters receives and decodes the signals radiated by the occupants to determine the number and location of the occupants. Additional receivers may be installed in specified regions to detect occupant intrusion into such regions, and in various control panels to assess driver distraction and to tailor the functional content and capability depending on whether a driver or non-driver is interacting with the control panel.
