1. A vehicle device control system comprising:
- a portable unit carried by a user; and
a vehicle-side unit mounted in a vehicle for performing bilateral communications with the portable unit,in each of the bilateral communications, the vehicle-side unit transmitting a first request signal in a predetermined area around the vehicle and the portable unit transmitting a first response signal in response to the first request signal of the vehicle-side unit, the vehicle-side unit transmitting a second request signal after a predetermined transmission interval specific to the vehicle-side unit and the portable unit transmitting a second response signal in response to the second request signal of the vehicle-side unit;
the vehicle-side unit checking an identification code included in the second response signal received from the portable unit with a pre-stored registration code, andthe vehicle-side unit controlling a vehicle device mounted in the vehicle on condition that a checkup result indicates a successful checkup operation,wherein the vehicle-side unit includes;
a vehicle-side transmission section for transmitting the first and second request signals to the portable unit;
a vehicle-side reception section for receiving the first and second response signals from the portable unit; and
a vehicle-side control section for instructing the vehicle-side transmission section to transmit the second request signal at the predetermined transmission interval specific to the vehicle side unit, when the first response signal is received from the portable unit by the vehicle-side reception section, andwherein the portable unit is operable with power supply from a battery, and includes;
a portable-side reception section for receiving the first and second request signals from the vehicle-side unit;
a portable-side transmission section for transmitting the first and second response signals to the vehicle-side unit;
a portable-side memory section for storing the transmission interval of the vehicle-side unit; and
a portable-side control section for instructing the portable-side transmission section to transmit the first response signal when the first request signal is received by the portable-side reception section, to not allow reception of the second request signal after transmitting the first response signal and to take the reception state after a specified period of time in correspondence to the transmission interval stored in the portable-side memory section;
whereinthe vehicle-side unit includesan operation detection section for detecting a predetermined operation on the vehicle by the user;
an operation time acquisition section for acquiring an operation time, at which the predetermined operation on the vehicle is detected by the operation detection section; and
a setting section for setting the transmission interval in correspondence to the operation time acquired by the operation time acquisition section and transmitting a set transmission interval to the portable unit, the set transmission interval being stored in the portable-side memory section as the transmission interval.

Abstract
A vehicle-side unit transmits a first request signal WAKE periodically toward a portable unit, and transmits a second request signal CHLG at every predetermined transmission interval specific to the vehicle-side unit upon reception of a first response signal ACK from the portable unit in response to the transmitted WAKE. The portable unit is operable with power supplied from a battery. The portable unit transmits ACK upon reception of WAKE and becomes ready for reception of CHLG at a timing CHLG is transmitted in accordance with the transmission interval specific to the vehicle-side unit.
