Abstract
A keyless entry apparatus includes an on-vehicle transmitting and receiving device mounted on a vehicle, and a portable transmitting and receiving device. The on-vehicle transmitting and receiving device has a plurality of antennas mounted close to members to be controlled of the vehicle, and a plurality of transmitting sections which are connected to the plurality of antennas and which transmit request signals having unique antenna IDs. The plurality of transmitting sections intermittently transmit request signals from the corresponding antennas. When the portable transmitting and receiving device receives any of the transmitted request signals, the portable transmitting and receiving device transmits an answer signal which controls the member to be controlled corresponding to the transmitting section which transmitted the received request signal.

6. A keyless entry apparatus comprising:
-
an on-vehicle transmitting and receiving device mounted on a vehicle; and
a portable transmitting and receiving device, wherein the on-vehicle transmitting and receiving device comprises a plurality of antennas mounted correspondingly to members to be controlled of the vehicle, a transmitting section which is connected to the plurality of antennas and which transmits a plurality of request signals having unique antenna IDs, and a door-handle-contact detecting section disposed at each door of the vehicle;
the transmitting section transmits the plurality of request signals through the corresponding antennas;
when the portable transmitting and receiving device receives any of the transmitted request signals, the portable transmitting and receiving device transmits an answer signal which controls the member to be controlled corresponding to the antenna which transmitted the received request signal; and
when the on-vehicle transmitting and receiving device receives the answer signal, only if the member to be controlled specified by the answer signal is a locking section of any door and the door-handle-contact detecting section of a door corresponding to the answer signal outputs a contact detecting signal, the on-vehicle transmitting and receiving device unlocks the door corresponding to the answer signal. - View Dependent Claims (7, 8, 9, 10)
