VEHICLE WIRELESS COMMUNICATION SYSTEM, VEHICLE CONTROL UNIT, AND HANDHELD EQUIPMENT
PROBLEM TO BE SOLVED: To upgrade a crime prevention capability against relay attack without making processing of a vehicle control unit or handheld equipment complex.SOLUTION: A vehicle control unit includes plural LF transmitters 2 to 6 that transmit a response request signal to an area around a vehicle 30 and a vehicle compartment, and a UHF receiver that receives a transmission signal sent from handheld equipment 20. The handheld equipment 20 includes an LF receiver that receives the response request signal, and a UHF transmitter that transmits a response signal. The LF receiver of the handheld equipment 20 has a receiving area E1 in which the LF receiver can receive response request signals sent from two or more of the LF transmitters 2 to 6 when the handheld equipment 20 approaches the vehicle 30. If the LF receiver of the handheld equipment 20 receives the response request signals, which are sent from two or more of the LF transmitters 2 to 6, within a predetermined period of time, unlocking doors is permitted. When the response request signal sent from one of the LF transmitters 2 to 6 is received, unlocking the doors is prohibited.SELECTED DRAWING: Figure 4
【課題】車両制御装置や携帯機の処理を複雑にすることなく、リレーアタックに対する防犯性を向上させる。【解決手段】車両制御装置は、車両３０の周囲近傍と車室内に行き渡るように応答要求信号を送信する複数のＬＦ送信部２〜６と、携帯機２０からの送信信号を受信するＵＨＦ受信部を備え、携帯機２０は、応答要求信号を受信するＬＦ受信部と、応答信号を送信するＵＨＦ送信部を備える。携帯機２０のＬＦ受信部は、携帯機２０の車両３０への接近時に、ＬＦ送信部２〜６のうち２つ以上から送信された応答要求信号を受信可能な受信領域Ｅ１を有する。携帯機２０のＬＦ受信部で、所定時間内に、ＬＦ送信部２〜６のうち２つ以上から送信された応答要求信号を受信した場合は、ドアの施解錠を許可し、ＬＦ送信部２〜６のうちいずれか１つから送信された応答要求信号を受信した場合は、ドアの施解錠を禁止する。【選択図】図４
