摘要： PROBLEM TO BE SOLVED: To provide a vehicular communication control system, an on-vehicle device, and a portable machine capable of easily establishing a suitable communication environment between the portable machine and the on-vehicle device. SOLUTION: A portable machine 10 has a communication control unit 11 which detects the reception level of the request signal when receiving the request signal to be transmitted from an on-vehicle device 20 and transmits the ID code signal including the reception level code to indicate the reception level. The on-vehicle device 20 has a vehicle control unit 21, and the vehicle control unit 21 compares the reception level to be indicated by the reception level code with the preset in-cabin boundary threshold and out-of-vehicle boundary threshold when receiving the ID code signal. As a result, the vehicle control unit 21 is in an engine start permissible state when it is determined that the reception level is higher than the in-cabin boundary threshold, or automatically unlocks the door lock when it is determined that the reception level is higher than the out-of-vehicle boundary threshold, and not higher than the in-cabin boundary threshold.

摘要： PROBLEM TO BE SOLVED: To provide an electronic key system which suitably secures communication characteristics between an electronic key and a transmitting antenna even when the transmitting antenna is arranged inside a vehicular pillar. SOLUTION: The transmitting antenna 13 is constituted of a coil-shaped antenna formed of a spirally wound conductive wire. The transmitting antenna 13 is arranged inside a front pillar Pa in such a way that the axial line of the transmitting antenna 13 is orthogonal to the axial line of the front pillar Pa when viewing a vehicle from the lateral direction. Accordingly, both the ends of the transmitting antenna 13 are made nearest to two side edge parts of the front pillar Pa which are positioned at the opposite sides to each other in the front-rear direction of the vehicle. So that a magnetic flux generated toward the outside of the vehicle of magnetic fluxes output from both ends of the transmitting antena 13 is suitably propagated to the outside of the vehicle through wraparound of the front pillar Pa. The detection area E of the electronic key 15 is suitably secured outside the compartment of the vehicle. COPYRIGHT: (C)2008,JPO&INPIT
摘要翻译：要解决的问题：即使当发送天线布置在车辆支柱内部时，也提供一种电子钥匙系统，其适当地确保电子钥匙和发送天线之间的通信特性。解决方案：发射天线13由螺旋卷绕的导线形成的线圈状天线构成。发送天线13配置在前柱Pa的内部，使得从横向观察车辆时，发送天线13的轴线与前柱Pa的轴线正交。因此，发射天线13的两端最靠近位于车辆前后方向上相对侧的前柱Pa的两个侧缘部分。因此，通过前柱Pa的卷绕，向从输送用电枢13的两端输出的磁通量的车辆外侧产生的磁通适当地传播到车辆的外部，电子钥匙15的检测区域被适当地固定在车辆的车厢外面。版权所有（C）2008，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide an antenna device the frame of which can be made compact while reducing the component cost, even if a resonance frequency adjustment mechanism is provided.SOLUTION: The out-vehicle transmitter (in-vehicle transmitter) of a vehicle comprises an antenna unit 14 for transmitting LF waves, for example. The antenna unit 14 includes a coil unit 16 where a coil 19 is wound multiple number of turns around a bobbin 18, and a core 17 having a high permeability. The antenna unit 14 includes a first resonance frequency adjustment mechanism 23 which adjusts the resonance frequency of the antenna by shifting the position of the core 17 for the coil 19. Inductance of the antenna, i.e., the resonance frequency, can thereby be adjusted by moving the core 17 in the axial direction of the coil for the coil unit 16 and aligning the core 17 and the coil unit 16.
