Abstract:
A remote control apparatus comprises a vehicle-mounted unit including a transmitter (26, 28, 23) for transmitting an ID request, a receiver (32, 33) for receiving a reply ID transmitted in response to the ID request, controller (31) for controlling the operation state of equipment (40, 60) depending on whether the receiver (32, 33) receives the ID, as well as a portable unit (10) for transmitting a reply ID in response to the ID request. When a hand sensor (1) provided in a door handle of a vehicle senses no hand and the receiver (32, 33) receives an ID, the controller (31) decreases the transmission power of the ID request. The hand sensor (1) comprises a slot antenna having an outside door handle, the surface of which is formed of a conductive material, a slit formed in the conductive material, and feeding points. The antenna is used for transmission of the ID request.
