Description

本発明は車両用のドアを自動で開閉するドア開閉制御装置に関する。 The present invention relates to a door opening / closing control device that automatically opens and closes a door for a vehicle.

従来、車両用のドアハンドルに静電容量センサ、または振動センサを取付けて、乗員がドアを開こうとする操作を検知するとともに、乗員が携帯する送受信装置と車載の制御装置間で交信して乗員を認識し、ドアロック装置を開錠するように制御する装置がある。 Conventionally, an electrostatic capacity sensor or vibration sensor is attached to a door handle for a vehicle to detect an operation of the occupant opening the door, and communication is performed between a transmission / reception device carried by the occupant and an in-vehicle control device. There is a device that recognizes an occupant and controls to unlock the door lock device.

例えば静電容量センサを利用する装置では、乗員の手のドアハンドルへ接近し、更に乗員がドアハンドルを握るときの継続した動作に伴って変化する静電容量を検知して、乗員がドアを開こうとしてドアハンドルを操作していると判定する。(例えば、特許文献１参照。)。
特開２００２−２９５０６４号公報 For example, in a device that uses a capacitance sensor, the passenger moves closer to the door handle of the occupant's hand, and further detects the capacitance that changes with continued operation when the occupant grips the door handle. It is determined that the door handle is being operated to open. (For example, see Patent Document 1).
JP 2002-295064 A

しかしながら、静電容量センサを使う場合、雨、雪などの車両周辺の環境によっても静電容量は変化しやすい。そのため静電容量センサはこれらの要因が原因で、変化した静電容量を検知して乗員がドアハンドルを操作したものと誤判定する可能性がある。ロック解錠からドア全開までを自動で行うシステムに用いた場合、乗員がドア付近を通っただけで、誤動作により、意思と関係なくドアが開いてしまう恐れがある。誤動作を防ぐには、静電容量センサの他に複数の他の方式のセンサを設ける必要があり、センサの搭載位置、組み付け性、コストに問題がある。 However, when a capacitance sensor is used, the capacitance is likely to change depending on the environment around the vehicle such as rain or snow. Therefore, there is a possibility that the capacitance sensor may erroneously determine that the passenger has operated the door handle by detecting the changed capacitance due to these factors. When used in a system that automatically performs the process from unlocking to fully opening the door, the passenger may pass through the vicinity of the door, and the door may be opened regardless of the intention due to a malfunction. In order to prevent malfunction, it is necessary to provide a plurality of other types of sensors in addition to the capacitance sensor, and there are problems with the sensor mounting position, assembling property, and cost.

以下に本発明の実施形態を図１〜４を参照しつつ詳細に説明する。 Hereinafter, embodiments of the present invention will be described in detail with reference to FIGS.

（第一実施形態）
図１は、本発明の第一実施形態の車両用のドア開閉制御装置１で、バックドア２の略中央部分には、バックドア２の開閉を操作する操作体３を備える。乗員が、バックドア２を開く場合には、操作体３に指を入れて操作する。 (First embodiment)
FIG. 1 shows a vehicle door opening / closing control apparatus 1 according to a first embodiment of the present invention, and an operating body 3 for operating opening / closing of the back door 2 is provided at a substantially central portion of the back door 2. When the occupant opens the back door 2, the occupant puts a finger on the operation body 3 and operates it.

図２は、ドア開閉制御装置１の操作体３の内部を模式的に示したものである。操作体３の内部には、バックドア２の開閉を制御する制御回路４（制御部）と、制御回路４に一端が固定された金属板圧電センサ５（圧電センサ）と、金属板圧電センサ５と接触して、乗員（人）と金属板圧電センサ５の間で、乗員の指の圧力を圧電センサ５に伝達する弾性力を有する緩衝部材６を備える。 FIG. 2 schematically shows the inside of the operating body 3 of the door opening / closing control apparatus 1. Inside the operating body 3 are a control circuit 4 (control unit) for controlling the opening and closing of the back door 2, a metal plate piezoelectric sensor 5 (piezoelectric sensor) having one end fixed to the control circuit 4, and a metal plate piezoelectric sensor 5. Is provided with a buffer member 6 having an elastic force for transmitting the pressure of the occupant's finger to the piezoelectric sensor 5 between the occupant (person) and the metal plate piezoelectric sensor 5.

第一実施形態におけるバックドア２の開閉操作について詳述する。まず、乗員は緩衝部材６の一端を金属板圧電センサ５の方向（矢印方向）に押圧する。緩衝部材６は弾力性を有するため金属板圧電センサの方向に圧縮されながら他端に接触する金属板圧電センサ５を押圧方向に押す。金属板圧電センサ５の一端は制御回路４に固定されているため、金属板圧電センサ５の他端側が押圧方向に押し上げられる。このときの金属板圧電センサ５からの検知信号は、制御回路４に送られ、図示しない駆動装置でバックドア２が開く。 The opening / closing operation of the back door 2 in the first embodiment will be described in detail. First, the occupant presses one end of the buffer member 6 in the direction of the metal plate piezoelectric sensor 5 (arrow direction). Since the buffer member 6 has elasticity, it presses the metal plate piezoelectric sensor 5 that contacts the other end in the pressing direction while being compressed in the direction of the metal plate piezoelectric sensor. Since one end of the metal plate piezoelectric sensor 5 is fixed to the control circuit 4, the other end of the metal plate piezoelectric sensor 5 is pushed up in the pressing direction. The detection signal from the metal plate piezoelectric sensor 5 at this time is sent to the control circuit 4, and the back door 2 is opened by a driving device (not shown).

また、バックドア２が開いた状態で乗員が緩衝部材６の一端を金属板圧電センサ５の方向に押圧すると、緩衝部材６は金属板圧電センサ５の方向に圧縮されながら他端に接触する金属板圧電センサ５を押圧方向に押す。金属板圧電センサ５の一端は制御回路４に固定されているため、金属板圧電センサ５の他端側が押圧方向に押し上げられる。このときの金属板圧電センサ５からの検知信号は、制御回路４に送られ、図示しない駆動装置でバックドア２を閉じる。 When the occupant presses one end of the buffer member 6 in the direction of the metal plate piezoelectric sensor 5 with the back door 2 opened, the buffer member 6 is compressed in the direction of the metal plate piezoelectric sensor 5 and contacts the other end. The plate piezoelectric sensor 5 is pushed in the pressing direction. Since one end of the metal plate piezoelectric sensor 5 is fixed to the control circuit 4, the other end of the metal plate piezoelectric sensor 5 is pushed up in the pressing direction. The detection signal from the metal plate piezoelectric sensor 5 at this time is sent to the control circuit 4 and the back door 2 is closed by a driving device (not shown).

本発明の第一実施形態のドア開閉制御装置１では、金属板圧電センサ５からの検知信号を受けてバックドア２の開閉を制御するため、従来の静電容量センサと比べて、車両周辺の環境による誤判定を防止できる。また、乗員の指の圧力を弾性力を有する緩衝部材６を介して金属板圧電センサ５に伝達するため、乗員がバックドア２を開閉するためには、一定のストロークをもって緩衝部材６を金属板圧電センサ５の方向に押す必要があり、乗員はバックドア２の開閉を操作する際に操作感が得られるため、乗員の意思に基づいて確実にバックドア２を開閉できる。また、車両のボディ等からの振動を緩衝部材６が吸収するため、金属板圧電センサ５の誤判定を防止できる。また、操作体３内に制御回路４、金属板圧電センサ５、緩衝部材６が配設さるため、複数のセンサを用いる場合と比べて、金属板圧電センサ５の搭載位置、組み付け性、コストに優れる。また、汎用部品である金属板圧電センサ５を用いることで、安価にドア開閉制御装置１を構成できる。また、腕力が必要なバックドア２の開閉を、乗員の指のわずかな操作で確実に行うことができる。 In the door opening / closing control device 1 according to the first embodiment of the present invention, the detection signal from the metal plate piezoelectric sensor 5 is received and the opening / closing of the back door 2 is controlled. Can prevent misjudgment due to the environment. Further, since the pressure of the occupant's finger is transmitted to the metal plate piezoelectric sensor 5 via the buffer member 6 having elasticity, the buffer member 6 is moved to the metal plate with a certain stroke in order for the occupant to open and close the back door 2. Since it is necessary to push in the direction of the piezoelectric sensor 5 and the occupant can feel the operation when opening and closing the back door 2, the back door 2 can be reliably opened and closed based on the intention of the occupant. Moreover, since the buffer member 6 absorbs vibration from the vehicle body or the like, erroneous determination of the metal plate piezoelectric sensor 5 can be prevented. Further, since the control circuit 4, the metal plate piezoelectric sensor 5, and the buffer member 6 are disposed in the operation body 3, the mounting position, assembling property, and cost of the metal plate piezoelectric sensor 5 are reduced as compared with the case where a plurality of sensors are used. Excellent. Moreover, by using the metal plate piezoelectric sensor 5 which is a general-purpose component, the door opening / closing control device 1 can be configured at low cost. In addition, the back door 2 that requires arm strength can be reliably opened and closed with a slight operation of the occupant's fingers.

（第二実施形態）
図３、図４は、本発明の第二実施形態の車両に取り付けたドア開閉制御装置１１の操作体１２の内部を模式的に示したものである。第一実施形態と同一または相当する構成部分は、同一の符号を用いて説明する。 (Second embodiment)
3 and 4 schematically show the inside of the operating body 12 of the door opening / closing control device 11 attached to the vehicle according to the second embodiment of the present invention. The same or corresponding components as those in the first embodiment will be described using the same reference numerals.

操作体１２の内部には、バックドア２の開閉を制御する制御回路１３（制御部）と、可撓性を有する圧電素子にて形成された可撓性圧電センサ１４と、可撓性圧電センサ１４を制御回路１３に固定する２つの固定部１５、１６と、可撓性圧電センサ１４を押圧する緩衝部材６を備える。可撓性圧電センサ１４は２つの固定部１５、１６の間で緩衝部材６と接触して、人の指が押す方向に押圧される。制御回路１３にはセンサ取付部１７が設けられており、センサ固定部１５、１６はセンサ取付部１７で可撓性電圧センサ１４を固定し、緩衝部材６からの圧力が、可撓性電圧センサ１４に伝達される構成である。
Inside the operating body 12, a control circuit 13 (control unit) for controlling the opening and closing of the back door 2, a flexible piezoelectric sensor 14 formed of a flexible piezoelectric element, and a flexible piezoelectric sensor Two fixing parts 15 and 16 for fixing 14 to the control circuit 13 and a buffer member 6 for pressing the flexible piezoelectric sensor 14 are provided. The flexible piezoelectric sensor 14 comes into contact with the buffer member 6 between the two fixing portions 15 and 16 and is pressed in the direction in which a human finger presses. The control circuit 13 is provided with a sensor mounting portion 17. The sensor fixing portions 15 and 16 fix the flexible voltage sensor 14 with the sensor mounting portion 17, and the pressure from the buffer member 6 is changed to the flexible voltage sensor. 14 is transmitted to 14.

第二実施形態におけるバックドア２の開閉操作について詳述する。まず、乗員は緩衝部材６の一端を可撓性圧電センサ１４の方向に押圧する。緩衝部材６は弾力性を有するため可撓性圧電センサ１４の方向に圧縮されながら他端に接触する可撓性圧電センサ１４を圧力方向に押圧する。可撓性圧電センサ１４は制御回路１３と接続されており、可撓性圧電センサ１４からの検知信号は、制御回路１３に送られ、図示しない駆動装置でバックドア２が開く。 The opening / closing operation of the back door 2 in the second embodiment will be described in detail. First, the occupant presses one end of the buffer member 6 toward the flexible piezoelectric sensor 14. Since the buffer member 6 has elasticity, the buffer member 6 is compressed in the direction of the flexible piezoelectric sensor 14 and presses the flexible piezoelectric sensor 14 in contact with the other end in the pressure direction. The flexible piezoelectric sensor 14 is connected to the control circuit 13, and a detection signal from the flexible piezoelectric sensor 14 is sent to the control circuit 13, and the back door 2 is opened by a driving device (not shown).

また、バックドア２が開いた状態で乗員が緩衝部材６の一端を可撓性圧電センサ１４の方向に押圧すると、緩衝部材６は可撓性圧電センサ１４の方向に圧縮されながら他端に接触する可撓性圧電センサ１４を圧力方向に押圧する。可撓性圧電センサ１４からの検知信号は、制御回路１３に送られ、図示しない駆動装置でバックドア２を閉じる。 When the occupant presses one end of the buffer member 6 in the direction of the flexible piezoelectric sensor 14 with the back door 2 opened, the buffer member 6 contacts the other end while being compressed in the direction of the flexible piezoelectric sensor 14. The flexible piezoelectric sensor 14 is pressed in the pressure direction. A detection signal from the flexible piezoelectric sensor 14 is sent to the control circuit 13 and the back door 2 is closed by a driving device (not shown).

本発明の第二実施形態のドア開閉制御装置１１では、第一実施形態のドア開閉制御装置１と同様に、可撓性圧電センサ１４からの検知信号を受けてバックドア２の開閉を制御するため、従来の静電容量センサと比べて、車両周辺の環境による誤判定を防止できる。また、乗員の指の圧力を弾性力を有する緩衝部材６を介して可撓性圧電センサ１４に伝達するため、乗員がバックドア２を開閉するためには、一定のストロークをもって緩衝部材６を可撓性圧電センサ１４の方向に押す必要があり、乗員はバックドア２の開閉を操作する際に操作感が得られるため、乗員の意志に基づいて確実にバックドア２を開閉できる。また、車両のボディ等からの振動を緩衝部材６が吸収するため、可撓性圧電センサ１４の誤判定を防止できる。また、操作体１２内に可撓性圧電センサ１４、緩衝部材６が配設さるため、複数のセンサを用いる場合と比べて、可撓性圧電センサ１４の搭載位置、組み付け性、コストに優れる。また、腕力が必要なバックドア２の開閉を、乗員の指のわずかな操作で行うことができる。また、可撓性圧電センサ１４は押圧することで、人の指の圧力を検知することができるため、金属板圧電センサ５のように圧力方向に変位させる必要がなく、操作体１２内にコンパクトに設置できる。 In the door opening / closing control device 11 according to the second embodiment of the present invention, similarly to the door opening / closing control device 1 according to the first embodiment, the detection signal from the flexible piezoelectric sensor 14 is received and the opening / closing of the back door 2 is controlled. Therefore, it is possible to prevent erroneous determination due to the environment around the vehicle as compared with the conventional capacitance sensor. Further, since the pressure of the occupant's finger is transmitted to the flexible piezoelectric sensor 14 via the buffer member 6 having elasticity, the buffer member 6 can be opened with a certain stroke in order for the occupant to open and close the back door 2. Since it is necessary to push in the direction of the flexible piezoelectric sensor 14, and the occupant can feel the operation when opening and closing the back door 2, the back door 2 can be reliably opened and closed based on the will of the occupant. In addition, since the buffer member 6 absorbs vibration from the vehicle body or the like, erroneous determination of the flexible piezoelectric sensor 14 can be prevented. In addition, since the flexible piezoelectric sensor 14 and the buffer member 6 are disposed in the operation body 12, the mounting position, the assembling property, and the cost of the flexible piezoelectric sensor 14 are superior to the case where a plurality of sensors are used. In addition, the back door 2 that requires arm strength can be opened and closed with a slight operation of the occupant's fingers. Further, since the pressure of the flexible piezoelectric sensor 14 can be detected by pressing, it is not necessary to be displaced in the pressure direction unlike the metal plate piezoelectric sensor 5, and the operation body 12 is compact. Can be installed.
