It is comprised so that it can judge by.

また、照合制御部１５は、第１車両側受信部１１または第２車両側受信部１２から応答信号を連続的または断続的に入力した時間または回数をカウントするカウント手段（図示しない）を有する。照合制御部１５は、このカウント手段のカウント結果により、照合制御部１５に入力された応答信号が、短い時間または少ない回数だけ入力される通常応答信号によるものか、連続的または断続的に長い時間または回数多く入力される短距離応答信号によるものかを判断する。照合制御部１５は、入力された応答信号が通常応答信号である場合、車両ＥＣＵ１６を介して車両機構３０に通常処理制御を実行させ、短距離応答信号である場合には、車両ＥＣＵ１６を介して車両機構３０に通常処理制御とは異なる第２処理制御を実行させる。通常処理制御及び第２処理制御については後述する。   Moreover, the collation control part 15 has a counting means (not shown) which counts the time or frequency | count that the response signal was input from the 1st vehicle side receiving part 11 or the 2nd vehicle side receiving part 12 continuously or intermittently. The collation control unit 15 determines whether the response signal input to the collation control unit 15 is based on a normal response signal input for a short time or a small number of times, or continuously or intermittently long time, based on the count result of the counting means. Or it is judged whether it is based on the short-range response signal inputted many times. When the input response signal is a normal response signal, the collation control unit 15 causes the vehicle mechanism 30 to perform normal processing control via the vehicle ECU 16. When the input response signal is a short-range response signal, the verification control unit 15 performs the normal processing control via the vehicle ECU 16. The vehicle mechanism 30 is caused to execute a second process control different from the normal process control. The normal process control and the second process control will be described later.

（携帯機２０の構成）
携帯機２０は、図１に示すように、車載制御装置１０から電波送信される携帯機探知信号を受信する携帯機側受信部２１と、車載制御装置１０に対して応答信号を電波送信する携帯機側送信部２２と、携帯機側制御部２３と、携帯機側送信部２２から電波送信される応答信号の出力強度を切り換える出力切替部２４と、各部に電力供給する電池（図示しない）と、を備え、車載制御装置１０からの携帯機探知信号に応答して、携帯機２０のＩＤコードを含む応答信号（アンサー信号）を車載制御装置１０に対して電波送信するものである。 (Configuration of portable device 20)
As shown in FIG. 1, the portable device 20 includes a portable device-side receiving unit 21 that receives a portable device detection signal transmitted from the in-vehicle control device 10 and a portable device that transmits a response signal to the in-vehicle control device 10. Machine-side transmitter 22, portable machine-side controller 23, output switching unit 24 that switches the output intensity of the response signal transmitted from the portable machine-side transmitter 22, and a battery (not shown) that supplies power to each unit The response signal (answer signal) including the ID code of the portable device 20 is transmitted to the in-vehicle control device 10 in response to the portable device detection signal from the on-vehicle control device 10.

携帯機側受信部２１は、車載制御装置１０から電波送信される携帯機探知信号を受信するＬＦ帯受信アンテナと、ＬＦ帯受信アンテナにより受信された受信電波を、例えばＡＳＫ）方式やＦＳＫ方式で電気信号に復調する復調回路と、電気信号を増幅する増幅回路と、を備えるものであり、車載制御装置１０から電波送信される携帯機探知信号（電波信号）を電気信号に変換して携帯機側制御部２３に出力するものである。   The portable device-side receiving unit 21 receives an LF band receiving antenna that receives a portable device detection signal transmitted from the in-vehicle control device 10 and an electric wave received by the LF band receiving antenna using, for example, the ASK method or the FSK method. A demodulating circuit for demodulating an electric signal and an amplifying circuit for amplifying the electric signal are provided, and a portable device detection signal (radio wave signal) transmitted from the in-vehicle controller 10 is converted into an electric signal. It outputs to the side control part 23.

携帯機側送信部２２は、携帯機側制御部２３から入力される応答信号（アンサー信号）を、例えばＡＳＫ方式やＦＳＫ方式でＵＨＦ帯の電波信号に変調する変調回路と、変調された応答信号をＵＨＦ帯の電波で電波送信するＵＨＦ帯送信アンテナと、を備えるものであり、携帯機側制御部２３からの応答信号（電気信号）を電波信号に変換して車載制御装置１０に電波送信するものである。   The portable device side transmission unit 22 modulates the response signal (answer signal) input from the portable device side control unit 23 into a radio signal in the UHF band by, for example, the ASK method or the FSK method, and the modulated response signal And a UHF band transmitting antenna that transmits a radio wave using a UHF band radio wave, and converts a response signal (electric signal) from the portable device side control unit 23 into a radio wave signal and transmits the radio wave signal to the in-vehicle controller 10. Is.

携帯機側制御部２３は、携帯機側ＣＰＵ２３１と、携帯機側メモリ２３２などを含むＥＣＵであり、携帯機側受信部２１と、携帯機側送信部２２と、出力切替部２４とに電気的に接続され、携帯機２０の電気的制御を行うものである。   The portable device side control unit 23 is an ECU including a portable device side CPU 231, a portable device side memory 232, etc., and is electrically connected to the portable device side receiving unit 21, the portable device side transmitting unit 22, and the output switching unit 24. To control the portable device 20 electrically.

携帯機側ＣＰＵ２３１は、携帯機側受信部２１から入力された電気信号と、携帯機側メモリ２３２に記憶されているデータとを照合し、携帯機側受信部２１から入力された電気信号が携帯機探知信号であるかを判定する。携帯機側ＣＰＵ２３１は、携帯機探知信号を入力した場合、携帯機側メモリ２３２に記憶された応答信号（アンサー信号）を読み出し、電気信号として携帯機側送信部２２へ出力する。   The portable device-side CPU 231 collates the electric signal input from the portable device-side receiving unit 21 with the data stored in the portable device-side memory 232, and the electric signal input from the portable device-side receiving unit 21 is portable. Determine if it is a machine detection signal. When the portable device detection signal is input, the portable device side CPU 231 reads the response signal (answer signal) stored in the portable device side memory 232 and outputs the response signal to the portable device side transmission unit 22 as an electrical signal.

また、携帯機側ＣＰＵ２３１は、携帯機２０が、第１車両側送信部１３から電波送信された通常携帯機探知信号のみ受信する状態（第１通信エリアＥ１内かつ第２通信エリアＥ２外）であるのか、第２車両側送信部１４から電波送信された短距離携帯機探知信号が受信できる状態（第２通信エリアＥ２内）にあるのかを判断する。   Further, the portable device-side CPU 231 is in a state where the portable device 20 receives only the normal portable device detection signal transmitted from the first vehicle-side transmitter 13 (inside the first communication area E1 and outside the second communication area E2). It is determined whether or not the short-range portable device detection signal transmitted from the second vehicle-side transmitter 14 can be received (within the second communication area E2).

携帯機側ＣＰＵ２３１は、図３に示すように、携帯機側受信部２１による携帯機探知信号の受信間隔の違いにより、通常携帯機探知信号のみ受信する状態であるか短距離携帯機探知信号を受信可能な状態であるかを判定する。
携帯機２０の位置が第１通信エリアＥ１内かつ第２通信エリアＥ２外である場合、携帯機側受信部２１は第１車両側送信部１３からの信号のみを受信するので、信号間隔が期間Ｔａとなる。携帯機側ＣＰＵ２３１は、入力した信号間隔が期間Ｔａである場合、携帯機２０が通常携帯機探知信号のみ受信する状態であると判定し、携帯機側送信部２１を介して通常応答信号を電波送信する。
また、携帯機２０の位置が第２通信エリアＥ２内である場合、携帯機側受信部２１は第１車両側送信部１３からの信号と第２車両側送信部１４からの信号を受信するので、信号間隔が期間Ｔｂとなる。携帯機側ＣＰＵ２３１は、入力した信号間隔が期間Ｔｂである場合、短距離携帯機探知信号が受信可能な状態であると判定し、出力切替部２４をオン状態にし、携帯機側送信部２１を介して短距離応答信号を電波送信する。 As shown in FIG. 3, the portable device side CPU 231 is in a state of receiving only a normal portable device detection signal or a short-range portable device detection signal due to a difference in reception interval of the portable device detection signal by the portable device side receiving unit 21. It is determined whether or not reception is possible.
When the position of the portable device 20 is within the first communication area E1 and outside the second communication area E2, the portable device-side receiving unit 21 receives only the signal from the first vehicle-side transmitting unit 13, so the signal interval is a period. Ta. When the input signal interval is the period Ta, the portable device side CPU 231 determines that the portable device 20 is in a state of receiving only the normal portable device detection signal, and transmits the normal response signal via the portable device side transmission unit 21 as a radio wave. Send.
Further, when the position of the portable device 20 is within the second communication area E2, the portable device-side receiver 21 receives a signal from the first vehicle-side transmitter 13 and a signal from the second vehicle-side transmitter 14. The signal interval becomes the period Tb. When the input signal interval is the period Tb, the portable device side CPU 231 determines that the short-range portable device detection signal is receivable, turns on the output switching unit 24, and sets the portable device side transmission unit 21. A short-range response signal is transmitted via radio.

出力切替部２４は、携帯機側制御部２３からの指示信号に従い、アンテナに供給される電流を調整することにより、携帯機側送信部２１から電波送信される応答信号の出力強度を制御するものであり、例えば可変抵抗器及び整合回路などから構成される。
出力切替部２４は、携帯機側ＣＰＵ２３１が携帯機側送信部２２を介して通常応答信号を出力する場合、アンテナに通常の大きさの電流を流す。また、携帯機側ＣＰＵ２３１が携帯機側送信部２２を介して短距離応答信号を出力する場合、出力切替部２４は、アンテナに通常より小さい電流を流す。斯かる構成により、通常応答信号は通信可能距離が比較的長い電波として送信され、短距離応答信号は消費電力を低く抑えた通信可能距離が比較的短い電波として送信される。 The output switching unit 24 controls the output intensity of the response signal transmitted from the portable device side transmission unit 21 by adjusting the current supplied to the antenna according to the instruction signal from the portable device side control unit 23. For example, it is composed of a variable resistor and a matching circuit.
When the portable device-side CPU 231 outputs a normal response signal via the portable device-side transmitter 22, the output switching unit 24 supplies a current having a normal magnitude to the antenna. Further, when the portable device-side CPU 231 outputs a short-range response signal via the portable device-side transmission unit 22, the output switching unit 24 causes a smaller current to flow through the antenna. With this configuration, the normal response signal is transmitted as a radio wave having a relatively long communicable distance, and the short distance response signal is transmitted as a radio wave having a relatively short communicable distance with low power consumption.

以上が本実施形態における車載制御装置１０と携帯機２０の構成であるが、これより車載制御装置１０と携帯機２０の動作処理について、図４，５を用いて説明する。   The above is the configuration of the in-vehicle control device 10 and the portable device 20 in the present embodiment, and the operation processing of the in-vehicle control device 10 and the portable device 20 will be described with reference to FIGS.

（認証処理）
まず、車載制御装置１０による携帯機２０の認証処理について図４を用いて説明する。ステップＡ１において、車載制御装置１０の照合制御部１５は、第１車両側送信部１３から通常携帯機探知信号を、第２車両側送信部１４から短距離携帯機探知信号を断続的に送信させる。 (Authentication process)
First, the authentication process of the portable device 20 by the in-vehicle control device 10 will be described with reference to FIG. In step A <b> 1, the verification control unit 15 of the in-vehicle control device 10 intermittently transmits the normal portable device detection signal from the first vehicle side transmission unit 13 and the short-range portable device detection signal from the second vehicle side transmission unit 14. .

ステップＢ１において、携帯機２０の携帯機側制御部２３は、携帯機側受信部２１から入力した電気信号のデータと携帯機側メモリ２３２に記憶されたデータと照合し、携帯機探知信号が入力されたか否かを判定する。   In step B <b> 1, the portable device side control unit 23 of the portable device 20 collates the electric signal data input from the portable device side reception unit 21 with the data stored in the portable device side memory 232, and the portable device detection signal is input. It is determined whether or not it has been done.

次に、携帯機側制御部２３は、図３に示すように、携帯機側受信部２１から入力される携帯機探知信号の受信間隔の違いにより、通常携帯機探知信号のみ受信する状態であるか短距離携帯機探知信号を受信可能な状態であるかを判定する。（ステップＢ２）   Next, as shown in FIG. 3, the portable device side control unit 23 is in a state of receiving only the normal portable device detection signal due to the difference in the reception interval of the portable device detection signal input from the portable device side reception unit 21. It is determined whether or not a short-range portable device detection signal can be received. (Step B2)

ステップＢ２において、携帯機側受信部２１から短距離携帯機探知信号が入力されたと判定した場合、携帯機側制御部２３は、ステップＢ３ａにおいて、出力切替部２４により応答信号の電波の出力強度を低出力に切り替え、ステップＢ４ａにおいて、携帯機側送信部２２から短距離応答信号を電波送信する。
また、ステップＢ２において、携帯機側受信部２１から入力された携帯機探知信号が通常携帯機探知信号であると判定した場合、携帯機側制御部２３は、ステップＢ３ｂにおいて、出力切替部２４により応答信号の電波の出力強度を通常出力に切り替え、ステップＢ４において、携帯機側送信部２２から通常応答信号を電波送信する。 If it is determined in step B2 that a short-range portable device detection signal has been input from the portable device-side receiving unit 21, the portable device-side control unit 23 uses the output switching unit 24 to set the output intensity of the response signal radio wave in step B3a. The output is switched to low output, and in step B4a, a short-range response signal is transmitted by radio wave from the portable device-side transmitter 22.
In Step B2, when it is determined that the portable device detection signal input from the portable device side receiving unit 21 is a normal portable device detection signal, the portable device side control unit 23 uses the output switching unit 24 in Step B3b. The output intensity of the radio wave of the response signal is switched to the normal output, and the normal response signal is radio wave transmitted from the portable device side transmission unit 22 in Step B4.

ステップＢ５において、携帯機側制御部２３は、携帯機側受信部２１から短距離携帯機探知信号が連続的または断続的に受信されているかを判定し、短距離携帯機探知信号が連続的または断続的に受信されている場合、携帯機側制御部２３は、ステップＢ４ａの短距離応答信号の電波送信を連続的または断続的に繰り返す。   In step B5, the portable device side control unit 23 determines whether the short-range portable device detection signal is continuously or intermittently received from the portable device-side reception unit 21, and the short-range portable device detection signal is continuously or In the case of being intermittently received, the portable device-side control unit 23 continuously or intermittently repeats the radio wave transmission of the short-range response signal in step B4a.

ステップＢ５において、短距離携帯機探知信号が連続的または断続的に受信されない場合、携帯機側制御部２３は、ステップＢ６において、出力切替部２４により応答信号の電波の出力強度を低出力に切り替える。   If the short-range portable device detection signal is not received continuously or intermittently in step B5, the portable device-side control unit 23 switches the output intensity of the response signal radio wave to low output by the output switching unit 24 in step B6. .

上記のように、携帯機側制御部２３は、携帯機側受信部２１からの短距離携帯機探知信号の受信状態に基づき、携帯機送信部２２から短距離応答信号を継続的に電波送信するかを判断するが、通常応答信号を送信する場合は、所定の時間または回数だけ通常応答信号を電波送信して終了する。   As described above, the portable device-side control unit 23 continuously transmits a short-range response signal from the portable device transmission unit 22 based on the reception state of the short-range portable device detection signal from the portable device-side reception unit 21. However, when the normal response signal is transmitted, the normal response signal is transmitted by radio wave for a predetermined time or number of times, and the process is terminated.

ステップＡ２において、車載制御装置１０の照合制御部１５は、第１車両側受信部１１または第２車両側受信部１２から入力した電気信号のＩＤコードとメモリ１５２に記憶された認証コードとを照合し、所定の応答信号が入力されたか否かを判定する。   In step A <b> 2, the collation control unit 15 of the in-vehicle control device 10 collates the ID code of the electrical signal input from the first vehicle side receiving unit 11 or the second vehicle side receiving unit 12 with the authentication code stored in the memory 152. Then, it is determined whether or not a predetermined response signal is input.

ステップＡ３において、照合制御部１５は、第１車両側受信部１１または第２車両側受信部１２のどちらから応答信号が入力されたかを、ＣＰＵ１５１の応答信号が入力される入力ポートの違いにより判定し、第１車両側受信部１１から入力された場合は通常応答信号であると判定し、第２車両側受信部１２から入力された場合は短距離応答信号であると判定する。また、入力された応答信号が連続的または断続的である場合、短距離応答信号を入力していると判定する。   In step A3, the collation control unit 15 determines whether the response signal is input from the first vehicle side receiving unit 11 or the second vehicle side receiving unit 12 based on the difference in the input port to which the response signal of the CPU 151 is input. When it is input from the first vehicle side receiving unit 11, it is determined to be a normal response signal, and when it is input from the second vehicle side receiving unit 12, it is determined to be a short distance response signal. When the input response signal is continuous or intermittent, it is determined that the short-range response signal is input.

ステップＡ３において、入力された応答信号が短距離応答信号であると判定された場合、車載制御装置１０は、車両ＥＣＵ１６を介して車両機構３０を第２制御処理にて操作する。
また、ステップＡ３において、入力された応答信号が通常応答信号であると判定された場合、車載制御装置１０は、車両ＥＣＵ１６を介して車両機構３０を通常制御処理にて操作する。 If it is determined in step A3 that the input response signal is a short-range response signal, the in-vehicle control device 10 operates the vehicle mechanism 30 in the second control process via the vehicle ECU 16.
In Step A3, when it is determined that the input response signal is a normal response signal, the in-vehicle control device 10 operates the vehicle mechanism 30 in the normal control process via the vehicle ECU 16.

次に通常制御処理と第２制御処理について説明する。
通常制御処理は、車両のドアのロック、アンロック制御であり、車載制御装置１０と携帯機２０との認証が終了した（ステップＡ２）後、ステップＡ５の状態にて、車両のドアスイッチ３１が押圧された場合、車両のドアロック３２によりドアをロック、アンロックする制御処理である。 Next, the normal control process and the second control process will be described.
The normal control processing is lock / unlock control of the vehicle door. After the authentication between the in-vehicle control device 10 and the portable device 20 is completed (step A2), the vehicle door switch 31 is set in the state of step A5. This is a control process for locking and unlocking the door with the door lock 32 of the vehicle when pressed.

第２制御処理は、車両のランプの断線検出処理やミラー操作処理また外部表示処理などである。第２制御処理の動作フローを図５に示す。ステップＡ４１において、車載制御装置１０は、車両ＥＣＵ１６を介して、テールランプ３３ａ、ストップランプ３３ｂ、バックランプ３３ｃ、リアターンシグナルランプ３３ｄに順次電流を供給し、その電流の異常を検出し、各ランプの正常、異常を車両の表示装置（図示しない）に表示させる断線検出を実行する。   The second control processing includes vehicle lamp break detection processing, mirror operation processing, external display processing, and the like. The operation flow of the second control process is shown in FIG. In step A41, the in-vehicle control device 10 sequentially supplies current to the tail lamp 33a, the stop lamp 33b, the back lamp 33c, and the rear turn signal lamp 33d via the vehicle ECU 16, detects an abnormality in the current, and detects each lamp's abnormality. Disconnection detection is performed to display normality and abnormality on a vehicle display device (not shown).

ステップＡ４２において、車載制御装置１０は、第２制御処理が完了したかを判定し、ステップＡ４３において短距離応答信号が継続受信されているかを判定し、継続受信がなされている間、第２制御処理の実行を継続させる（ステップＡ４１乃至Ａ４３を繰り返す）。   In step A42, the in-vehicle control device 10 determines whether or not the second control process is completed, determines whether or not the short-range response signal is continuously received in step A43, and performs the second control while the continuous reception is being performed. The execution of the process is continued (steps A41 to A43 are repeated).

ステップＡ４３において短距離応答信号が未受信になった場合、車載制御装置１０（ＣＰＵ１５１）は、ステップＡ４４において、短距離応答信号をどのくらい連続的または断続的に入力したかの時間または回数のカウント結果に基づき、第２制御処理を実行中の車両機構３０を、最終状態へ遷移させる。   When the short-range response signal is not received in step A43, the in-vehicle controller 10 (CPU 151) counts the time or the number of times of continuous or intermittent input of the short-range response signal in step A44. Based on the above, the vehicle mechanism 30 that is executing the second control process is shifted to the final state.

最終状態とは、第２制御処理前の状態と、第２制御処理完了の状態とである。短距離応答信号が未受信になった際、カウント結果が所定値未満であれば、ＣＰＵ１５１は車両機構３０を第２制御処理前の状態に遷移させ、カウント結果が所定値以上であれば、ＣＰＵ１５１は車両機構３０を第２制御処理完了の状態に遷移させる。
断線検出において、第２制御処理前の状態とは、断線検出の結果を何も表示装置に表示させない状態であり、第２制御処理完了の状態とは、ランプ全ての断線検出を完了させ、表示装置に表示させた状態である。 The final state is a state before the second control process and a state after the completion of the second control process. When the short-range response signal is not received, if the count result is less than the predetermined value, the CPU 151 causes the vehicle mechanism 30 to transition to the state before the second control process, and if the count result is equal to or greater than the predetermined value, the CPU 151. Makes the vehicle mechanism 30 transition to a state in which the second control process is completed.
In the disconnection detection, the state before the second control processing is a state in which the result of the disconnection detection is not displayed on the display device, and the state of the second control processing completion is the state in which the detection of disconnection of all the lamps is completed and displayed. This is the state displayed on the device.

以上の車両用遠隔制御システムを構成する車載制御装置１０及び携帯機２０によって、車外から車両に備えられた車両機構を制御する場合において、意図しない誤動作を防止し、さらにムダな電力消費を防止することができる。   When controlling the vehicle mechanism provided in the vehicle from outside the vehicle by the in-vehicle control device 10 and the portable device 20 constituting the above-described vehicle remote control system, an unintended malfunction is prevented and further wasteful power consumption is prevented. be able to.

本実施形態に係る車両用遠隔制御システムは、車両側に搭載された複数の車両側受信部１１，１２及び車両側送信部１３，１４を有し、車両に備えられた車両機構３０を制御する車載制御装置１０と、ユーザが所持する携帯機２０とで構成され、車両側送信部１３，１４が携帯機２０に対して携帯機探知信号を電波送信し、携帯機２０が携帯機探知信号に基づく応答信号を電波送信し、車載制御装置１０が応答信号に基づき車両機構３０の制御処理を実行する車両用遠隔制御システムにおいて、携帯機は、応答信号の出力強度を、通常出力と通常出力より通信可能距離の短い低出力とで切り換える出力切替手段（２３，２４）を有し、車両側受信部（１１，１２）は、短距離応答信号を受信する第２車両側受信部１２を有し、第２車両側受信部１２が短距離応答信号を連続的または断続的に受信した際、車載制御装置１０は、通常の前記応答信号を受信した場合と異なる前記車両機構３０の第２制御処理を実行する。斯かる構成により、携帯機２０からの短距離の無線信号にのみ第２制御処理を実行するので、車両から離れた位置で携帯機２０の誤操作を行なった場合は、第２制御処理を実行しないので、車両側の誤動作を防止することができる。さらに、携帯機２０からの短距離応答信号を連続的または断続的に受信した場合のみ第２制御処理を実行するので、車両に近い位置で携帯機の誤操作を行なった場合にも、第２制御処理を実行しないので、車両側の誤動作を防止することができる。   The vehicle remote control system according to the present embodiment includes a plurality of vehicle-side receivers 11 and 12 and vehicle-side transmitters 13 and 14 mounted on the vehicle side, and controls a vehicle mechanism 30 provided in the vehicle. The in-vehicle control device 10 and a portable device 20 possessed by the user are configured, and the vehicle-side transmitters 13 and 14 transmit a portable device detection signal to the portable device 20 by radio waves, and the portable device 20 converts the portable device detection signal into the portable device detection signal. In the vehicle remote control system in which the response signal based on the radio wave is transmitted and the in-vehicle control device 10 executes the control process of the vehicle mechanism 30 based on the response signal, the portable device determines the output intensity of the response signal from the normal output and the normal output. It has output switching means (23, 24) for switching between a low output with a short communicable distance, and the vehicle side receiver (11, 12) has a second vehicle side receiver 12 for receiving a short distance response signal. , Second vehicle side reception When 12 is continuously or intermittently receive the short-range response signal, the onboard control unit 10 executes the second control process different from the case of receiving normal of the response signal the vehicle mechanism 30. With such a configuration, the second control process is executed only for a short-distance radio signal from the portable device 20, and therefore, if the portable device 20 is erroneously operated at a position away from the vehicle, the second control process is not executed. Therefore, malfunction on the vehicle side can be prevented. Furthermore, since the second control process is executed only when the short-range response signal from the portable device 20 is received continuously or intermittently, the second control is performed even when the portable device is erroneously operated near the vehicle. Since the process is not executed, a malfunction on the vehicle side can be prevented.

なお、車両側送信部（１３，１４）は、第１車両側送信部１３と、第２車両側受信部１２の近傍に配設されて第１車両側送信部１３よりも通信可能距離の短い携帯機探知信号である短距離携帯機探知信号を電波送信する第２車両側送信部１４とを有し、携帯機２０は、短距離携帯機探知信号を受信した場合、出力切替手段（２３，２４）により短距離応答信号を電波送信する。斯かる構成により、携帯機２０に操作部を設けることなく携帯機２０が送信する電波の通信可能距離を切り換えることができ、部品費を削減できる。また、第２車両側受信部１２に近づいてから携帯機２０から短距離応答信号を電波送信することで、第２車両側受信部１２に受信されない位置から携帯機２０が短距離応答信号を電波送信することによるムダな電力消費を削減することが出来る。   The vehicle-side transmitters (13, 14) are arranged in the vicinity of the first vehicle-side transmitter 13 and the second vehicle-side receiver 12 and have a shorter communicable distance than the first vehicle-side transmitter 13. And a second vehicle-side transmitter 14 that transmits a short-range portable device detection signal that is a portable device detection signal. When the portable device 20 receives the short-range portable device detection signal, the output switching means (23, 24) A short-range response signal is transmitted by radio wave. With such a configuration, the communicable distance of the radio wave transmitted by the portable device 20 can be switched without providing an operation unit in the portable device 20, and the parts cost can be reduced. Further, the mobile device 20 transmits a short-range response signal from a position not received by the second vehicle-side receiver 12 by transmitting a short-range response signal from the mobile device 20 after approaching the second vehicle-side receiver 12. Wasted power consumption due to transmission can be reduced.

また、通常応答信号の信号データと、短距離応答信号の信号データは同一であり、車載制御装置１０は、応答信号を受信した箇所を判定する受信位置判定手段（１５１）を有し、短距離応答信号を第２車両側受信部１２より受信することにより、車両機構３０に第２制御処理を実行させてなる。斯かる構成により、携帯機側メモリ２３２に予め記憶するデータ容量を削減できる。   Further, the signal data of the normal response signal and the signal data of the short-range response signal are the same, and the vehicle-mounted control device 10 includes a reception position determination unit (151) that determines a location where the response signal is received, By receiving the response signal from the second vehicle-side receiver 12, the vehicle mechanism 30 is caused to execute the second control process. With this configuration, the data capacity stored in advance in the portable device side memory 232 can be reduced.

第２制御処理の実行時、第２車両側受信部１４近傍でユーザが第２制御処理の実行を認知可能な報知手段（３０）を有し、斯かる構成により、ユーザは携帯機２０を保持したその位置のまま第２制御処理が実行されたことを、認識することができる。   At the time of execution of the second control process, there is a notification means (30) in which the user can recognize the execution of the second control process in the vicinity of the second vehicle side receiving unit 14, and the user holds the portable device 20 by such a configuration. Thus, it can be recognized that the second control process has been executed at that position.

第２制御処理は、車両のランプ３３の断線検出処理であり、車載制御装置１０は、第２制御処理の実行時、少なくともユーザが視認可能なランプ３３を点灯させ、ランプ３３に流れる電流により断線検出を行ない、車外から誤動作なく、各ランプ３３を視認しながら断線検出をすることができる。   The second control process is a disconnection detection process of the lamp 33 of the vehicle, and the in-vehicle control device 10 lights at least the lamp 33 visible to the user when executing the second control process, and the disconnection is caused by the current flowing through the lamp 33. It is possible to detect the disconnection while visually recognizing each lamp 33 without any malfunction from outside the vehicle.

第２制御処理は、車両のサイドミラー３５の開閉処理であり、車載制御装置１０は、第２制御処理の実行時、少なくともユーザが視認可能なサイドミラー３５を開閉動作させ、車外から誤動作なく、サイドミラー３５を視認しながら開閉処理することができる。   The second control process is an opening / closing process of the side mirror 35 of the vehicle, and the in-vehicle control device 10 opens / closes at least the side mirror 35 visible to the user when the second control process is executed, so that there is no malfunction from outside the vehicle. Opening and closing can be performed while visually recognizing the side mirror 35.

車両は、フロントガラスまたはドアガラスまたはリアガラスを含むガラス部に表示画像を投影する外部表示手段（ＨＵＤ装置）３４を有し、第２制御処理は、外部表示手段３４の表示処理であり、車載制御装置１０は、第２制御処理の実行時、少なくともユーザが視認可能なガラス部に表示画像を表示させ、車外から誤動作なく視認可能な位置で表示画像を視認することができる。   The vehicle has an external display means (HUD device) 34 that projects a display image on a glass portion including a windshield, a door glass, or a rear glass, and the second control process is a display process of the external display means 34, and is controlled in the vehicle. When the second control process is executed, the device 10 can display a display image on at least a glass part that can be visually recognized by the user, and can visually recognize the display image at a position that can be visually recognized without malfunction.

車載制御装置１０は、第２制御処理が完了する前に、第２車両側受信部１２による短距離応答信号が未受信状態になった場合、車両機構３０を、第２制御処理前の状態または前記第２制御処理完了後の状態に遷移させるものであり、途中で第２車両側受信部１２による短距離応答信号が未受信状態になった場合、半端な状態で車両機構３０が維持されてしまうのを防止することができ、また、車両機構３０が再駆動するために、車両機構３０がどの状態にあるかを一時的にＲＯＭなどに記憶する際に、半端な状態を記憶する必要がなく複雑な処理を省くことができる。   If the short-range response signal from the second vehicle-side receiving unit 12 is not received before the second control process is completed, the in-vehicle control device 10 changes the vehicle mechanism 30 to the state before the second control process or If the short-range response signal from the second vehicle-side receiver 12 is not received during the transition to the state after the completion of the second control process, the vehicle mechanism 30 is maintained in an odd state. In addition, since the vehicle mechanism 30 is re-driven, it is necessary to memorize an incomplete state when temporarily storing the state of the vehicle mechanism 30 in a ROM or the like. And complicated processing can be omitted.

車載制御装置１０は、短距離応答信号を連続的または断続的に受信した時間または回数をカウントするカウント手段（１５１）を有し、カウント手段（１５１）によるカウント結果に基づき、第２車両側受信部１２による短距離応答信号が未受信状態になった後の車両機構３０の遷移状態を決定する遷移状態決定手段（１５１）を有し、短距離応答信号を送信する携帯機２０がどれだけの期間、第２車両側受信部１２付近に保持されたかを読み取り、第２制御処理をキャンセルしたい場合、または第２制御処理を完了させたいが間違えて携帯機２０を第２車両側受信部１２から離してしまった場合にも、ユーザの意図を、動作が行なわれた期間であるカウント結果から読み取ることができ、これらのユーザの意図を車両機構３０の最終状態として反映することができる。   The vehicle-mounted control device 10 has a counting means (151) that counts the time or number of times the short-range response signal has been received continuously or intermittently, and receives the second vehicle side reception based on the count result by the counting means (151). What is the portable device 20 having the transition state determining means (151) for determining the transition state of the vehicle mechanism 30 after the short-range response signal from the unit 12 is not received, and transmitting the short-range response signal If it is desired to cancel the second control process by reading whether it has been held near the second vehicle side receiving unit 12 during the period, or the second control process is to be completed, the portable device 20 is mistakenly received from the second vehicle side receiving unit 12. Even if the user's intention has been released, the user's intention can be read from the count result that is the period during which the operation has been performed. It is possible to reflect Te.

携帯機２０は、第２車両側送信部１４からの短距離携帯機探知信号が未受信状態になった場合、短距離応答信号を電波送信する状態から通常応答信号を電波送信する状態に切り換えるものであり、斯かる構成により、携帯機２０が送信する短距離応答信号が、第２車両側受信部１４に届かない位置に携帯機２０が移動した場合に、直ちに自動的に携帯機２０の連続（断続）送信を停止することができ、ムダな消費電力を削減することができる。   The portable device 20 switches from a state in which a short-range response signal is transmitted by radio wave to a state in which a normal response signal is transmitted by radio wave when the short-range portable device detection signal from the second vehicle-side transmitter 14 is not received. With such a configuration, when the portable device 20 moves to a position where the short-range response signal transmitted by the portable device 20 does not reach the second vehicle-side receiver 14, the portable device 20 is automatically and continuously connected. (Intermittent) Transmission can be stopped and wasteful power consumption can be reduced.
