特開２０１３−００７１７１号公報JP 2013-007171 A

しかしながら、特許文献１の自動開制御装置では、ユーザを区別することなく所定の動作を検出してスイングドアを開閉するので、乗員以外の人が意図せずに該所定の動作をしてしまうと、スイングドアが自動的に開閉してしまうことになる。   However, in the automatic opening control device of Patent Document 1, a predetermined operation is detected without distinguishing the user and the swing door is opened and closed. Therefore, if a person other than the passenger unintentionally performs the predetermined operation. The swing door will automatically open and close.

このように車両の動開制御装置では、車両の開閉部またはその鍵を開こうと意図した乗員の動作とその他の人の動作とを識別して、意図した乗員の動作により開閉部またはその鍵を開くようにすることが求められている。   As described above, in the vehicle opening / closing control device, the operation of the occupant who intends to open the opening / closing portion of the vehicle or its key and the operation of another person are identified, and the opening / closing portion or its key is determined by the intended operation of the occupant. Is required to open.

本発明に係る車両の自動開制御装置は、車両の開閉部またはその鍵を開く自動開制御装置であって、乗員が携帯するワイヤレスキーと通信する無線通信機と、前記車両または前記開閉部に設けられ、前記乗員の所定の動作を検出する静電容量センサと、前記無線通信機および前記動作センサが接続される制御部と、を有し、前記制御部は、前記無線通信機に前記ワイヤレスキーと通信させることにより前記ワイヤレスキーを携帯する前記乗員と前記静電容量センサとの距離を計測し、前記静電容量センサが前記乗員の所定の動作を検出した際の前記乗員と前記静電容量センサとの距離が、前記乗員が前記静電容量センサに対して前記所定の動作をすることが可能な所定の最大距離以下である場合、前記開閉部またはその鍵を開く。   An automatic opening control device for a vehicle according to the present invention is an automatic opening control device that opens an opening / closing part of a vehicle or a key thereof, a wireless communication device that communicates with a wireless key carried by an occupant, and the vehicle or the opening / closing part. A capacitance sensor that detects a predetermined movement of the occupant, and a control unit to which the wireless communication device and the movement sensor are connected, and the control unit is connected to the wireless communication device by the wireless communication device. The distance between the occupant carrying the wireless key and the electrostatic capacity sensor is measured by communicating with the key, and the occupant and the electrostatic capacity when the electrostatic capacity sensor detects a predetermined operation of the occupant are measured. When the distance to the capacitance sensor is equal to or less than a predetermined maximum distance at which the occupant can perform the predetermined operation with respect to the capacitance sensor, the opening / closing part or its key is opened.

好適には、前記制御部は、前記ワイヤレスキーを携帯する前記乗員毎に、前記静電容量センサに対して前記所定の動作をすることが可能な前記最大距離を切り換える、とよい。   Preferably, the control unit switches the maximum distance at which the predetermined operation can be performed with respect to the capacitance sensor for each occupant carrying the wireless key.

好適には、前記無線通信機は、前記静電容量センサの近くにまたは並べて配置され、前記制御部は、前記無線通信機が受信した前記ワイヤレスキーの電波強度または前記無線通信機と前記ワイヤレスキーとの通信にかかる時間に基づいて前記乗員と前記静電容量センサとの距離を計測する、とよい。   Preferably, the wireless communication device is disposed near or side by side with the capacitance sensor, and the control unit is configured such that the wireless key receives the radio field intensity of the wireless key received by the wireless communication device or the wireless communication device and the wireless key. It is good to measure the distance of the said passenger | crew and the said capacitance sensor based on the time concerning communication with.

本発明では、車両または開閉部に設けられる静電容量センサが乗員の所定の動作を検出した際の乗員と静電容量センサとの距離が、乗員が静電容量センサに対して所定の動作をすることが可能な所定の最大距離以下である場合、開閉部またはその鍵を開く。
よって、ワイヤレスキーを携帯する乗員が静電容量センサに対して所定の動作をしたことを検出することができる。しかも、ワイヤレスキーを携帯する乗員以外の人が静電容量センサに対して所定の動作をしたとしても、静電容量センサの近くに該人が存在することによりワイヤレスキーを携帯する乗員が最大距離より離れた位置となり、ワイヤレスキーを携帯する乗員以外の人による所定の動作により開閉部またはその鍵を開いてしまう可能性を抑えることができる。
すなわち、車両の開閉部またはその鍵を開こうと意図した乗員の動作とその他の人の動作とを識別して、意図した乗員の動作により開閉部またはその鍵を開き、それ以外の場合には開閉部またはその鍵を開き難くすることができる。 In the present invention, the distance between the occupant and the capacitance sensor when the electrostatic capacity sensor provided in the vehicle or the opening / closing unit detects the predetermined operation of the occupant indicates that the occupant performs the predetermined operation with respect to the electrostatic capacity sensor. When the distance is equal to or smaller than a predetermined maximum distance, the opening / closing part or its key is opened.
Therefore, it can be detected that the passenger carrying the wireless key has performed a predetermined operation on the capacitance sensor. In addition, even if a person other than the passenger carrying the wireless key performs a predetermined operation on the capacitance sensor, the passenger who carries the wireless key can reach the maximum distance because the person exists near the capacitance sensor. The position is further away, and the possibility of opening the opening / closing part or the key by a predetermined operation by a person other than the passenger carrying the wireless key can be suppressed.
That is, the movement of the occupant who intends to open the opening / closing part of the vehicle or its key and the movement of another person are identified, and the opening / closing part or its key is opened by the intended occupant's movement. The opening / closing part or its key can be made difficult to open.

以下、本発明の実施形態を図面に基づいて説明する。   Hereinafter, embodiments of the present invention will be described with reference to the drawings.

図１は、本発明の実施形態に係る自動車１を示す模式図である。自動車１は車両の一例である。図１は、自動車１を側面から見た図である。自動車１の車体２には、エンジン室３、車室４、が設けられる。   FIG. 1 is a schematic diagram showing an automobile 1 according to an embodiment of the present invention. The automobile 1 is an example of a vehicle. FIG. 1 is a side view of the automobile 1. The vehicle body 2 of the automobile 1 is provided with an engine compartment 3 and a compartment 4.

車室４の後側には荷物を入れる際に開閉するバックゲート５が設けられる。バックゲート５は、その上縁を中心として下縁が後上方へ開くように車体２に取り付けられる。この他にも、車室４の左右両側には乗員が乗降する際に開閉するドアが設けられる。ドアは、たとえばその前縁を中心として後縁が外方へ開くように車体２に取り付けられる。   A back gate 5 is provided on the rear side of the passenger compartment 4 to open and close when luggage is put. The back gate 5 is attached to the vehicle body 2 so that its lower edge opens rearward and upward with its upper edge as the center. In addition, doors that are opened and closed when passengers get on and off are provided on the left and right sides of the passenger compartment 4. For example, the door is attached to the vehicle body 2 such that the rear edge opens outward with the front edge as the center.

そして、図１の自動車１には、バックゲート５を自動的に開く自動開制御装置１０が設けられる。自動開制御装置１０は、バックゲート５を駆動するアクチュエータ１１と、バックゲート５の近くに設けられる静電容量センサ１２と、乗員が携帯するワイヤレスキー１４と通信する無線通信機１５と、これらが接続されるＥＣＵ（Electronic Control Unit）１３と、を有する。   The automobile 1 shown in FIG. 1 is provided with an automatic opening control device 10 that automatically opens the back gate 5. The automatic opening control device 10 includes an actuator 11 that drives the back gate 5, a capacitance sensor 12 provided near the back gate 5, a wireless communication device 15 that communicates with a wireless key 14 carried by an occupant, and ECU (Electronic Control Unit) 13 to be connected.

アクチュエータ１１は、たとえばモータ、油圧シリンダである。アクチュエータ１１は、バックゲート５を車体２に対して開閉する駆動力を発生する。バックゲート５は、上下方向に沿った状態で車体２に対して閉じられた全閉位置と、水平方向に沿った状態で車体２から後方へ延在する全開位置との間で開閉される。   The actuator 11 is, for example, a motor or a hydraulic cylinder. The actuator 11 generates a driving force that opens and closes the back gate 5 with respect to the vehicle body 2. The back gate 5 is opened and closed between a fully closed position that is closed with respect to the vehicle body 2 in a state along the vertical direction and a fully open position that extends rearward from the vehicle body 2 in a state along the horizontal direction.

静電容量センサ１２は、たとえば電極板と、電極板とバッテリとの間に接続される電流検出器と、を有する。電極板には、たとえばバッテリの電圧が印加されることにより電荷が蓄積する。電極板には、その周囲の導体たとえば地面との間の容量に応じた電荷が蓄積される。電荷が蓄えられた状態でたとえば電極板との地面との間に人の足が侵入すると、電極板と地面との間の静電容量が変化し、それに応じた電流が電流検出器に流れる。静電容量センサ１２は、電極板に電荷を蓄えた後の容量変化を電流検出器により検出し、検出信号を生成する。
そして、静電容量センサ１２は、バックゲート５の下に位置する車体２のリアバンパー６に設けられる。これにより、電極板は、たとえばリアバンパー６の下の地面との間で容量的に結合し易くなる。静電容量センサ１２は、リアバンパー６の下側近くにおける人のキック動作を検出し、検出信号を生成できる。 The capacitance sensor 12 includes, for example, an electrode plate and a current detector connected between the electrode plate and the battery. Electric charges accumulate on the electrode plate when, for example, a battery voltage is applied. The electrode plate accumulates electric charges according to the capacity between the surrounding conductors such as the ground. For example, when a person's foot enters between the electrode plate and the ground while the electric charge is stored, the capacitance between the electrode plate and the ground changes, and a current corresponding to the capacitance flows to the current detector. The capacitance sensor 12 detects a change in capacitance after the electric charge is stored in the electrode plate, and generates a detection signal.
The capacitance sensor 12 is provided on the rear bumper 6 of the vehicle body 2 located below the back gate 5. As a result, the electrode plate is easily capacitively coupled with the ground below the rear bumper 6, for example. The capacitance sensor 12 can detect a human kicking action near the lower side of the rear bumper 6 and generate a detection signal.

無線通信機１５は、無線通信により乗員が携帯するワイヤレスキー１４との間で双方向の通信を実施する。ワイヤレスキー１４は、ワイヤレスキー１４毎に固有の識別情報を無線通信機１５へ送信する。これにより、ワイヤレスキー１４を携帯する乗員を、他の乗員から区別することができる。ワイヤレスキー１４と無線通信機１５との間の通信データは暗号化されてよい。
そして、無線通信機１５は、静電容量センサ１２の近くにおいて静電容量センサ１２と並べて、車体２のリアバンパー６に設けられる。これにより、無線通信機１５は、たとえば静電容量センサ１２を中心とした所定の狭い範囲、たとえば球形の範囲においてワイヤレスキー１４と通信可能とすることができる。 The wireless communicator 15 performs bidirectional communication with the wireless key 14 carried by the passenger by wireless communication. The wireless key 14 transmits identification information unique to each wireless key 14 to the wireless communication device 15. Thereby, the crew member who carries wireless key 14 can be distinguished from other crew members. Communication data between the wireless key 14 and the wireless communication device 15 may be encrypted.
The wireless communication device 15 is provided in the rear bumper 6 of the vehicle body 2 along with the capacitance sensor 12 near the capacitance sensor 12. Accordingly, the wireless communication device 15 can communicate with the wireless key 14 in a predetermined narrow range centered on the capacitance sensor 12, for example, a spherical range.

ＥＣＵ１３は、たとえば自動車１において電子装置等を制御するために設けられるコンピュータ装置である。ＥＣＵ１３には、アクチュエータ１１、無線通信機１５、および静電容量センサ１２が接続される。ＥＣＵ１３は、そのメモリに記憶されているプログラムを実行することにより自動車１の各部を制御する。本実施形態では特に、静電容量センサ１２の検出信号に基づいてバックゲート５の自動開制御を実行する。   ECU13 is a computer apparatus provided in order to control an electronic device etc. in the motor vehicle 1, for example. An actuator 11, a wireless communication device 15, and a capacitance sensor 12 are connected to the ECU 13. The ECU 13 controls each part of the automobile 1 by executing a program stored in the memory. In the present embodiment, in particular, the automatic opening control of the back gate 5 is executed based on the detection signal of the capacitance sensor 12.

また、ＥＣＵ１３のメモリには、ワイヤレスキー１４毎に、それを携帯する乗員の体格に応じた検出範囲の設定データが登録される。検出範囲の設定データは、たとえば無線通信機１５を中心とした球形の検出範囲についての半径といった最大距離でよい。この場合、大人の最大距離は、子供の最大距離より大きく設定される。また、各最大距離は、たとえば大人二人が入ることが難しいような距離に設定する。   In addition, in the memory of the ECU 13, setting data for a detection range corresponding to the physique of the passenger carrying the wireless key 14 is registered for each wireless key 14. The detection range setting data may be a maximum distance such as a radius of a spherical detection range centered on the wireless communication device 15, for example. In this case, the maximum distance for adults is set larger than the maximum distance for children. Each maximum distance is set to a distance that makes it difficult for two adults to enter.

次に、ＥＣＵ１３によるバックゲート５の自動開制御について説明する。   Next, automatic opening control of the back gate 5 by the ECU 13 will be described.

図２は、ＥＣＵ１３によるバックゲート５の自動開制御の流れを示すフローチャートである。図３は、バックゲート５を自動開制御する際の乗員の動きの説明図である。   FIG. 2 is a flowchart showing the flow of the automatic opening control of the back gate 5 by the ECU 13. FIG. 3 is an explanatory view of the movement of the occupant when the back gate 5 is automatically opened.

図２に示すように、バックゲート５の自動開制御において、ＥＣＵ１３は、まず、ワイヤレスキー１４と通信可能であるか判断する（ステップＳＴ１）。ＥＣＵ１３は、無線通信機１５の出力を最大距離の場合より大きい所定の出力に設定し、ワイヤレスキー１４との通信を試みる。
そして、ワイヤレスキー１４と通信できた場合、ＥＣＵ１３は、無線通信機１５を用いてワイヤレスキー１４から識別情報を取得し（ステップＳＴ２）、取得した識別情報に予め対応付けられた最大距離を取得する（ステップＳＴ３）。 As shown in FIG. 2, in the automatic opening control of the back gate 5, the ECU 13 first determines whether or not communication with the wireless key 14 is possible (step ST1). The ECU 13 attempts to communicate with the wireless key 14 by setting the output of the wireless communication device 15 to a predetermined output that is greater than the maximum distance.
If the communication with the wireless key 14 is successful, the ECU 13 acquires identification information from the wireless key 14 using the wireless communication device 15 (step ST2), and acquires the maximum distance previously associated with the acquired identification information. (Step ST3).

その後、静電容量センサ１２からキック動作の検出信号が入力されると（ステップＳＴ４）、ＥＣＵ１３は、無線通信機１５とワイヤレスキー１４との間の通信を実施する（ステップＳＴ５）。ＥＣＵ１３は、無線通信機１５からリクエストを送信し、ワイヤレスキー１４はレスポンスを送信する。ＥＣＵ１３は、リクエストの送信からレスポンスの受信までの通信にかかる時間を内蔵タイマで計測し、計測した時間から乗員と静電容量センサ１２との距離を計測する。なお、ＥＣＵ１３は、無線通信機１５が受信したワイヤレスキー１４の電界強度に基づいて、乗員と静電容量センサ１２との距離を計測してもよい。   Thereafter, when a detection signal for kicking operation is input from the capacitance sensor 12 (step ST4), the ECU 13 performs communication between the wireless communication device 15 and the wireless key 14 (step ST5). The ECU 13 transmits a request from the wireless communication device 15, and the wireless key 14 transmits a response. The ECU 13 measures the time required for communication from the transmission of the request to the reception of the response with the built-in timer, and measures the distance between the occupant and the capacitance sensor 12 from the measured time. The ECU 13 may measure the distance between the occupant and the capacitance sensor 12 based on the electric field strength of the wireless key 14 received by the wireless communication device 15.

そして、計測した距離がワイヤレスキー１４に対応する最大距離以下である場合、ＥＣＵ１３は、ワイヤレスキー１４を携帯する乗員がキック操作したと判断し、ステップＳＴ６の判断の後にバックゲート５を実際に自動的に開く制御を開始する（ステップＳＴ７）。ＥＣＵ１３は、内蔵タイマの計測時間に基づいて操作した乗員が離れるために十分な所定時間（たとえば１０秒）経過したことを判断した後、アクチュエータ１１によりバックゲート５を駆動させる。これにより、閉じていたバックゲート５が自動的に開く。   If the measured distance is less than or equal to the maximum distance corresponding to the wireless key 14, the ECU 13 determines that the occupant carrying the wireless key 14 has performed a kick operation, and the back gate 5 is actually automatically operated after the determination in step ST6. Open control is started (step ST7). The ECU 13 drives the back gate 5 by the actuator 11 after determining that a predetermined time (for example, 10 seconds) sufficient for the occupant to operate based on the measurement time of the built-in timer has passed. Thereby, the closed back gate 5 is automatically opened.

このような制御により、図３に示すように、ワイヤレスキー１４を携帯する乗員がバックゲート５に近づき、キック操作をし、そのキック操作時にワイヤレスキー１４が検出されると、閉じていたバックゲート５を自動的に開くことができる。   By such control, as shown in FIG. 3, when the occupant carrying the wireless key 14 approaches the back gate 5 and performs a kick operation, and the wireless key 14 is detected during the kick operation, the back gate that has been closed is closed. 5 can be opened automatically.

本実施形態では、車体２のリアバンパー６に設けられる静電容量センサ１２が乗員のキック動作を検出した際の乗員と車体２との計測距離が、乗員が静電容量センサ１２に対してキック動作をすることが可能な所定の最大距離以下である場合、バックゲート５を開く。よって、ワイヤレスキー１４を携帯する乗員が静電容量センサ１２に対してキック動作をしたことを検出することができる。しかも、ワイヤレスキー１４を携帯する乗員以外の人が静電容量センサ１２に対してキック動作をしたとしても、該人がいることによりワイヤレスキー１４を携帯する乗員は最大距離より離れた場所に位置することになるので、ワイヤレスキー１４を携帯する乗員以外の人による意図しないキック動作によりバックゲート５を開いてしまうことが起き難い。すなわち、バックゲート５を開こうと意図した乗員のキック動作とその他の人のキック動作とを識別して、意図した乗員のキック動作によりバックゲート５を開き、意図しない人のキック動作によりバックゲート５を開かないようにできる。   In the present embodiment, the measurement distance between the occupant and the vehicle body 2 when the electrostatic capacity sensor 12 provided on the rear bumper 6 of the vehicle body 2 detects the occupant's kicking motion is such that the occupant kicks with respect to the electrostatic capacity sensor 12. When the distance is equal to or less than a predetermined maximum distance that can be operated, the back gate 5 is opened. Therefore, it can be detected that the occupant carrying the wireless key 14 has kicked the capacitance sensor 12. Moreover, even if a person other than the occupant carrying the wireless key 14 performs a kick operation on the capacitance sensor 12, the occupant carrying the wireless key 14 is located at a place away from the maximum distance due to the presence of the person. Therefore, it is unlikely that the back gate 5 is opened by an unintended kick operation by a person other than the passenger carrying the wireless key 14. That is, the occupant's kicking action intended to open the backgate 5 is distinguished from the kicking action of another person, the backgate 5 is opened by the intended occupant's kicking action, and the unintended person's kicking action causes the backgate to open. 5 can be prevented from opening.

本実施形態では、静電容量センサ１２に対してキック動作をすることが可能な最大距離を複数の乗員に対して固定的に設けるのではなく、ワイヤレスキー１４を携帯する乗員毎に切り換えている。よって、該最大距離は乗員毎に好適となるように切り換えられ、各乗員が動作可能な狭い範囲を、静電容量センサ１２を含む最小限の最大距離とすることができ、最大距離の範囲内に該乗員と同時に他の人が入り込み難くできる。   In this embodiment, the maximum distance at which the kick operation can be performed with respect to the capacitance sensor 12 is not fixed for a plurality of occupants, but is switched for each occupant carrying the wireless key 14. . Therefore, the maximum distance is switched so as to be suitable for each occupant, and a narrow range in which each occupant can operate can be set as a minimum maximum distance including the capacitance sensor 12, and is within the range of the maximum distance. This makes it difficult for other people to enter at the same time as the passenger.

以上の実施形態は、本発明の好適な実施形態の例であるが、本発明はこれに限定されるものではなく発明の要旨を逸脱しない範囲において種々の変形または変更が可能である。   The above embodiment is an example of a preferred embodiment of the present invention, but the present invention is not limited to this, and various modifications or changes can be made without departing from the scope of the invention.

たとえば上記実施形態では、無線通信機１５は、静電容量センサ１２の近くに配置されている。この他にもたとえば、無線通信機１５は、車体２において静電容量センサ１２から離れた位置に配置されてもよい。この場合でも、静電容量センサ１２を含んでいるたとえばドーナッツ形状の所定の距離範囲内についてワイヤレスキー１４を携帯する乗員を検出するようにすることで、略同様の効果を期待し得る。   For example, in the above embodiment, the wireless communication device 15 is disposed near the capacitance sensor 12. In addition to this, for example, the wireless communication device 15 may be disposed at a position away from the capacitance sensor 12 in the vehicle body 2. Even in this case, substantially the same effect can be expected by detecting an occupant carrying the wireless key 14 within a predetermined distance range of, for example, a donut shape including the capacitance sensor 12.

上記実施形態において動作センサは、静電容量センサ１２であり、乗員によるキック動作を検出している。この他にもたとえば、動作センサは、乗員の手や足による所定の動作を検出してもよい。また、動作センサとしてカメラを使用してもよい。   In the above-described embodiment, the motion sensor is the capacitance sensor 12 and detects a kick motion by the occupant. In addition to this, for example, the motion sensor may detect a predetermined motion by a passenger's hand or foot. A camera may be used as the motion sensor.
