ABSTRACT:
A portable unit locating system is incorporated in a vehicle equipment control system including a portable unit and an in-vehicle unit, which communicate each other for controlling vehicle equipment such as doors. The in-vehicle unit includes inside transmitters, a receiver, a comparison ECU and a display. The transmitters transmit respective request signals in a vehicle compartment. The comparison ECU determines whether any response signal has been received from the portable unit in response the request signals, while gradually varying output levels of the request signals. The comparison ECU then specifies a location of the portable unit based on a change in determination results. The display visually or audibly notifies the specified location of the portable unit to a vehicle user.
