COMMUNICATION SYSTEM FOR VEHICLE AND ON-VEHICLE UNIT
PROBLEM TO BE SOLVED: To provide a communication system for a vehicle, capable of accurately determining whether or not a mobile unit is present in a cabin regardless of rotational position, even in a case where an antenna that transmits a signal for determining whether or not the mobile unit is in a cabin is disposed at a movable part of a vehicle.SOLUTION: A communication system for a vehicle includes an on-vehicle unit which transmits a signal through a plurality of antennas provided at a vehicle, and a mobile unit which receives the signal that is transmitted from the on-vehicle unit and transmits a response signal according to the received signal. The on-vehicle unit receives the response signal that is transmitted from the mobile unit, and based on the received response signal, determines whether or not the mobile unit is in a cabin. At least one antenna is arranged at a movable part supported rotatably around a shaft part 52a provided at the vehicle, and includes a rod-like magnetic body core 31a, and a coil 31b wound around the magnetic body core 31a, with a length direction of the magnetic body core 31a being almost parallel to the shaft part 52a.SELECTED DRAWING: Figure 3
【課題】携帯機が車室内にあるか否かを判定するための信号を送信するアンテナが車両の可動部に配されている場合であっても、その回動位置に拘わらず、携帯機が車室内にあるか否かを正確に判定することが可能な車両用通信システムを提供する。【解決手段】車両用通信システムは、車両に設けられた複数のアンテナから信号を送信する車載機と、該車載機から送信された信号を受信し、受信した信号に応じた応答信号を送信する携帯機とを備える。車載機は該携帯機から送信された応答信号を受信し、受信した応答信号に基づいて、前記携帯機が車室内にあるか否かを判定する。少なくとも一のアンテナは、前記車両に設けられた軸部５２ａの周りに回動可能に支持された可動部に配されており、棒状の磁性体コア３１ａと、該磁性体コア３１ａの外周に巻かれたコイル３１ｂとを備え、前記磁性体コア３１ａの長手方向は、軸部５２ａに対して略平行である。【選択図】図３
