特開２００８−２８４９６９号公報JP 2008-284969 A

しかしながら、上記従来技術においては、乗員がいちいち操作指示を行わないと、駐車目標位置を調整することができない。適切な駐車支援を実施するためには、駐車目標位置を自動で設定する際に、ドライバの嗜好を反映した適切な駐車目標位置を設定可能とするのが望ましい。   However, in the above-described prior art, the parking target position cannot be adjusted unless the occupant performs an operation instruction one by one. In order to implement appropriate parking assistance, it is desirable to be able to set an appropriate parking target position that reflects the driver's preference when the parking target position is automatically set.

本発明の目的は、ドライバの嗜好を反映した適切な駐車目標位置の自動設定を可能とする運転情報記録装置を提供することである。   An object of the present invention is to provide a driving information recording apparatus capable of automatically setting an appropriate parking target position that reflects a driver's preference.

本発明は、駐車目標位置への駐車動作を支援する機能を有する車両に搭載される運転情報記録装置であって、車両の駐車状態を判断する判断手段と、判断手段により車両が駐車したと判断されたときに、車両の駐車位置に関する情報を記録する記録手段とを備えることを特徴とするものである。   The present invention relates to a driving information recording device mounted on a vehicle having a function of assisting a parking operation at a parking target position, a determination unit that determines a parking state of the vehicle, and a determination unit that determines that the vehicle is parked. And a recording means for recording information relating to the parking position of the vehicle.

このような運転情報記録装置において、例えば手動運転により車両を駐車した場合は、車両の駐車位置に関する情報として車両の実駐車位置の情報を記録する。この場合には、その後で自動運転により車両を駐車する際に、手動運転時に表れるドライバの嗜好に応じた駐車目標位置が学習により自動的に設定されるようになる。これにより、ドライバの嗜好を反映した適切な駐車目標位置を自動設定することが可能となる。   In such a driving information recording device, for example, when the vehicle is parked by manual driving, information on the actual parking position of the vehicle is recorded as information on the parking position of the vehicle. In this case, when the vehicle is parked by automatic driving after that, the parking target position corresponding to the preference of the driver appearing during manual driving is automatically set by learning. This makes it possible to automatically set an appropriate parking target position that reflects the driver's preference.

好ましくは、記録手段は、車両の駐車位置に関する情報として、駐車目標位置の情報と駐車目標位置が自動で設定されたか否かの情報とを記録する。   Preferably, the recording unit records information on the parking target position and information on whether or not the parking target position is automatically set as information on the parking position of the vehicle.

自動運転により車両を駐車する場合でも、目標駐車位置の設定だけは手動で行うことがある。目標駐車位置の設定を手動で行うときは、ドライバの嗜好に応じた駐車目標位置が設定されるはずである。この場合には、その後で自動運転において目標駐車位置が自動で設定される際に、ドライバの嗜好に応じた駐車目標位置が学習により設定されるようになる。従って、この場合にもドライバの嗜好を反映した適切な駐車目標位置を自動設定することが可能となる。   Even when the vehicle is parked by automatic driving, only the target parking position may be set manually. When setting the target parking position manually, the parking target position corresponding to the driver's preference should be set. In this case, when the target parking position is automatically set thereafter in automatic driving, the parking target position corresponding to the driver's preference is set by learning. Accordingly, in this case as well, it is possible to automatically set an appropriate parking target position that reflects the driver's preference.

また、好ましくは、判断手段は、車両が自動運転及び手動運転の何れにより駐車状態に至ったかを判断し、記録手段は、判断手段により判断された車両の駐車状態に至るまでの経緯を併せて記録する。   Preferably, the determination means determines whether the vehicle has reached a parking state by automatic driving or manual operation, and the recording means also includes a history until the vehicle has reached the parking state determined by the determination means. Record.

この場合には、例えば車両の駐車動作完了の直前に手動運転から自動運転に切り換わっても、手動運転により車両を駐車したものと判断できるため、車両の駐車位置に関する情報として正確な実駐車位置の情報を記録することが可能となる。   In this case, for example, even if switching from manual driving to automatic driving immediately before the completion of the parking operation of the vehicle, it can be determined that the vehicle is parked by manual driving. This information can be recorded.

本発明によれば、ドライバの嗜好を反映した適切な駐車目標位置の自動設定が可能となるので、ドライバにとって適切な駐車支援を実施することができる。   According to the present invention, since it is possible to automatically set an appropriate parking target position that reflects the driver's preference, it is possible to implement parking support appropriate for the driver.

以下、本発明に係わる運転情報記録装置の好適な実施形態について、図面を参照して詳細に説明する。なお、図面において同一または同等の要素には同じ符号を付し、重複する説明を省略する。   DESCRIPTION OF EMBODIMENTS Hereinafter, a preferred embodiment of an operation information recording apparatus according to the present invention will be described in detail with reference to the drawings. In the drawings, the same or equivalent elements are denoted by the same reference numerals, and redundant description is omitted.

図１は、本発明に係わる運転情報記録装置の第１実施形態の概略を示すブロック図である。同図において、本実施形態の運転情報記録装置１は、車両に搭載され、車両が駐車場所に駐車されるときの運転情報を記録する装置である。   FIG. 1 is a block diagram showing an outline of a first embodiment of an operation information recording apparatus according to the present invention. In the figure, a driving information recording device 1 of the present embodiment is a device that is mounted on a vehicle and records driving information when the vehicle is parked in a parking place.

運転情報記録装置１はＥＣＵ（Electronic Control Unit）２を備え、このＥＣＵ２には、センサ部３、入力部４及び自動駐車支援装置５が接続されている。センサ部３は、周辺環境情報（他車両の情報、交通情報、路面情報等）や自車両情報（位置、方向、車速、エンジン状態等）を検出する。   The driving information recording device 1 includes an ECU (Electronic Control Unit) 2, and a sensor unit 3, an input unit 4, and an automatic parking assistance device 5 are connected to the ECU 2. The sensor unit 3 detects surrounding environment information (information on other vehicles, traffic information, road surface information, etc.) and host vehicle information (position, direction, vehicle speed, engine state, etc.).

入力部４は、ドライバが操作行動を入力するためのハンドル、ペダル、スイッチ、ボタン及びキー等である。操作行動としては、手動運転と自動運転との切換操作、車両の駐車動作を自動運転で行う場合におけるドライバによる駐車目標位置（駐車向きを含む）の設定等が挙げられる。   The input unit 4 includes a handle, a pedal, a switch, a button, a key, and the like for the driver to input an operation action. Examples of the operation behavior include switching operation between manual driving and automatic driving, and setting of a parking target position (including parking direction) by the driver when the parking operation of the vehicle is performed by automatic driving.

自動駐車支援装置５は、車両の駐車動作を自動運転で行う際の支援を行う装置である。具体的には、自動駐車支援装置５は、入力部４により又は自動的に設定された駐車目標位置に車両が駐車されるように、車両のハンドル、アクセル及びブレーキを自動制御する。   The automatic parking assistance device 5 is a device that provides assistance when performing a parking operation of a vehicle by automatic driving. Specifically, the automatic parking assist device 5 automatically controls the steering wheel, the accelerator, and the brake of the vehicle so that the vehicle is parked at the parking target position set by the input unit 4 or automatically.

ＥＣＵ２は、駐車判別部６と、駐車記憶部７とを有している。駐車判別部６は、センサ部３からの出力信号に基づいて、自車両が駐車したか否かを判別し、更に自車両が駐車したと判別されたときに、入力部４及び自動駐車支援装置５からの出力信号に基づいて、自車両が手動運転及び自動運転のうち何れの方法で駐車したかを判別する。   The ECU 2 includes a parking determination unit 6 and a parking storage unit 7. The parking discriminating unit 6 discriminates whether or not the host vehicle is parked based on the output signal from the sensor unit 3 and further determines that the host vehicle is parked. On the basis of the output signal from 5, the vehicle is discriminated by which method of manual driving and automatic driving.

具体的には、駐車判別部６は、自車両が駐車枠内に入って停車した段階で駐車状態と判別しても良いし、自車両が駐車枠内に入ってイグニッションスイッチがオフになった段階で駐車状態と判別しても良い。なお、停車とは、車速がゼロになった状態であり、駐車に遷移する前段階の車速がゼロであるときは、停車と定められる。   Specifically, the parking determination unit 6 may determine that the vehicle is in a parking state when the host vehicle enters the parking frame and stops, or the host vehicle enters the parking frame and the ignition switch is turned off. It may be determined that the vehicle is parked at a stage. Stopping is a state in which the vehicle speed has become zero, and when the vehicle speed at the previous stage of transition to parking is zero, it is determined to stop.

また、駐車判別部６は、入力部４の切換操作状態から自車両が手動運転及び自動運転のうち何れの方法で駐車したかを判別しても良いし、自動駐車支援装置５による駐車ロジックが完了したときに自動運転による駐車と判別しても良い。   In addition, the parking determination unit 6 may determine from the switching operation state of the input unit 4 whether the own vehicle has been parked by manual driving or automatic driving, and the parking logic by the automatic parking assist device 5 may be determined. When completed, it may be determined as parking by automatic driving.

駐車記憶部７は、駐車判別部６により得られた情報を記憶（記録）する。具体的には、駐車記憶部７は、自車両が駐車したと判別されたときに、自車両が手動運転及び自動運転のうち何れの方法で駐車したかという情報を記憶する。   The parking storage unit 7 stores (records) information obtained by the parking determination unit 6. Specifically, when it is determined that the host vehicle is parked, the parking storage unit 7 stores information on which method the host vehicle is parked by manual driving or automatic driving.

このとき、上記の手動運転及び自動運転の情報に加えて、自車両の実際の駐車位置及び駐車方向等を含む自車両情報を記憶する。また、車両の駐車動作を自動運転で行う場合には、「ドライバが入力部４により駐車目標位置を設定した」または「自動駐車支援装置５が駐車目標位置を自動で設定した」という情報も併せて記憶する。さらに、駐車時刻の情報、周辺環境情報（他車両の情報、交通情報、路面情報等）を併せて記憶しても良い。なお、新しい情報を記憶するときは、古い情報に上書きしても良いし、古い情報に上書きせずに保存しても良い。   At this time, in addition to the information on the above-described manual driving and automatic driving, the host vehicle information including the actual parking position and parking direction of the host vehicle is stored. In addition, when the vehicle is parked by automatic driving, information such as “the driver has set the parking target position by the input unit 4” or “the automatic parking assist device 5 has automatically set the parking target position” is also included. Remember. Furthermore, information on parking time and surrounding environment information (information on other vehicles, traffic information, road surface information, etc.) may be stored together. When new information is stored, the old information may be overwritten, or the old information may be stored without being overwritten.

自動駐車支援装置５は、駐車目標位置を自動的に設定するときは、駐車記憶部７に記憶された情報に基づいて駐車目標位置を設定する。   When automatically setting the parking target position, the automatic parking assistance device 5 sets the parking target position based on the information stored in the parking storage unit 7.

具体的には、自車両の駐車動作が手動運転で行われたときは、自車両の実際の駐車位置及び駐車方向の情報が駐車記憶部７に記憶される。手動運転時には、車両前方や車両右側にマージンを取りたい等といったドライバの嗜好を反映して駐車されるはずである。このため、その後に自動駐車支援装置５を用いて自車両の駐車動作を自動運転で行う場合に、駐車目標位置の設定も自動で行うときは、手動運転時に表れるドライバの嗜好を考慮した実際の駐車位置及び駐車方向が学習（フィードバック）されて、駐車目標位置として設定されるようになる。   Specifically, when the parking operation of the host vehicle is performed manually, information on the actual parking position and parking direction of the host vehicle is stored in the parking storage unit 7. At the time of manual driving, the vehicle should be parked reflecting the driver's preference such as wanting a margin in front of the vehicle or on the right side of the vehicle. For this reason, when the parking operation of the host vehicle is performed by automatic driving using the automatic parking assist device 5 after that, when the parking target position is also set automatically, the actual driver taking into account the driver's preference that appears during manual driving. The parking position and parking direction are learned (feedback) and set as the parking target position.

また、自車両の駐車動作が自動運転で行われる場合でも、駐車目標位置の設定だけはドライバの手動操作により行われるときは、ドライバの嗜好を反映した駐車目標位置が選択されるはずである。このため、その後に自動駐車支援装置５を用いて自車両の駐車動作を自動運転で行う場合に、駐車目標位置の設定も自動で行うときは、先にドライバにより選択された駐車目標位置が学習（フィードバック）されて、駐車目標位置として設定されるようになる。   Further, even when the parking operation of the host vehicle is performed by automatic driving, when only the setting of the parking target position is performed by the manual operation of the driver, the parking target position reflecting the driver's preference should be selected. For this reason, when the automatic parking assist device 5 is used to perform the parking operation of the host vehicle by automatic driving, the parking target position previously selected by the driver is learned when the parking target position is also set automatically. (Feedback) and set as a parking target position.

以上において、ＥＣＵ２の駐車判別部６は、車両の駐車状態を判断する判断手段を構成する。同駐車記憶部７は、判断手段により車両が駐車したと判断されたときに、車両の駐車位置に関する情報を記録する記録手段を構成する。   In the above, the parking discrimination | determination part 6 of ECU2 comprises the judgment means which judges the parking state of a vehicle. The parking storage unit 7 constitutes a recording unit that records information on the parking position of the vehicle when the determination unit determines that the vehicle is parked.

以上のように本実施形態によれば、自動駐車支援装置５を利用して自動運転により自車両を駐車する際に、駐車目標位置が自動で設定されるときは、ドライバの嗜好を反映した適切な駐車目標位置が設定されるようになる。これにより、ドライバにとって適切な駐車支援を実現することが可能となる。   As described above, according to the present embodiment, when the parking target position is automatically set when the host vehicle is parked by automatic driving using the automatic parking assist device 5, the driver's preference is appropriately reflected. A correct parking target position is set. Thereby, it becomes possible to implement | achieve parking assistance appropriate for a driver.

図２は、上記第１実施形態の変形例の概略を示すブロック図である。同図において、ＥＣＵ２は、上記の駐車判別部６と、記憶内容設定部１１と、駐車状態記憶部１２とを有している。   FIG. 2 is a block diagram showing an outline of a modification of the first embodiment. In the figure, the ECU 2 includes the parking determination unit 6, a storage content setting unit 11, and a parking state storage unit 12.

記憶内容設定部１１は、手動運転による駐車（手動駐車）及び自動運転による駐車（自動駐車）のうち何れの駐車方法を記憶するかを設定する。このとき、回数の少ないほうの駐車方法を記憶するのが望ましい。この場合には、手動駐車及び自動駐車の駐車回数比が変わったときは、記憶すべき駐車方法を変更する必要がある。   The storage content setting unit 11 sets which parking method to store between parking by manual driving (manual parking) and parking by automatic driving (automatic parking). At this time, it is desirable to store the parking method with the smaller number of times. In this case, when the parking ratio of manual parking and automatic parking changes, it is necessary to change the parking method to be stored.

駐車状態記憶部１２は、手動駐車及び自動駐車のうち記憶内容設定部１１で設定された駐車方法による駐車が開始されたという情報を記憶すると共に、その駐車が解除された（完了した）という情報を記憶する。   The parking state storage unit 12 stores information that parking by the parking method set in the storage content setting unit 11 among manual parking and automatic parking is started, and information that the parking is canceled (completed). Remember.

例えば図３に示すように、まず自動駐車を行い、続いて手動駐車を行い、続いて自動駐車を２回連続して行った場合には、回数の少ない手動駐車が開始された時刻情報と、手動駐車が解除された時刻情報とを記憶する。そうすることで、それ以外の駐車は自動駐車であることが分かる。また、手動駐車が解除されたという情報を記憶することで、時刻４の駐車状態のときに、時刻２の駐車状態が継続しているのではないと認識することが可能となる。   For example, as shown in FIG. 3, when automatic parking is performed first, then manual parking is performed, and then automatic parking is performed twice in succession, time information when manual parking with a small number of times is started, The time information when manual parking is released is stored. By doing so, it is understood that other parking is automatic parking. In addition, by storing information that manual parking has been canceled, it is possible to recognize that the parking state at time 2 is not continuing when the parking state is at time 4.

このように手動駐車及び自動駐車のうち何れか一方のみの情報を記憶することにより、駐車状態記憶部１２に記憶されるデータ量（記憶容量）を削減することができる。   Thus, by storing only one of manual parking and automatic parking, the amount of data (storage capacity) stored in the parking state storage unit 12 can be reduced.

図４は、上記第１実施形態の他の変形例の概略を示すブロック図である。同図において、ＥＣＵ２は、上記の駐車判別部６及び駐車記憶部７と、記憶削除判別部１３とを有している。   FIG. 4 is a block diagram showing an outline of another modification of the first embodiment. In the figure, the ECU 2 includes the parking determination unit 6, the parking storage unit 7, and the memory deletion determination unit 13.

記憶削除判別部１３は、駐車記憶部７に記憶された古い情報を削除すべきか否かを判別する。具体的には、記憶削除判別部１３は、駐車回数が規定回数に達したとき、記憶容量が規定容量に達したとき、駐車日数が規定日数に達したときの何れかにおいて、古い情報から削除する。このとき、記憶削除判別部１３は、外部と通信を行って規定日数を更新しても良い。   The memory deletion determination unit 13 determines whether or not the old information stored in the parking storage unit 7 should be deleted. Specifically, the memory deletion determination unit 13 deletes from the old information when the number of parking reaches the specified number, when the storage capacity reaches the specified capacity, or when the number of parking days reaches the specified number of days. To do. At this time, the memory deletion determination unit 13 may update the specified number of days by communicating with the outside.

以上により、駐車状態記憶部７に記憶されたデータがある程度残るようになるため、手動運転時に表れるドライバの嗜好を考慮した駐車位置を精度良く取得しつつ、記憶容量の増大を抑えることができる。   As described above, data stored in the parking state storage unit 7 remains to some extent, so that an increase in storage capacity can be suppressed while accurately obtaining a parking position that takes into account the driver's preference that appears during manual operation.

図５は、本発明に係わる運転情報記録装置の第２実施形態の概略を示すブロック図である。同図において、本実施形態の運転情報記録装置１は、第２実施形態におけるＥＣＵ２に代えてＥＣＵ２０を備えている。   FIG. 5 is a block diagram showing an outline of the second embodiment of the operation information recording apparatus according to the present invention. In the figure, the driving information recording apparatus 1 of this embodiment includes an ECU 20 instead of the ECU 2 in the second embodiment.

ＥＣＵ２０は、走行データ記憶部２１と、駐車判別部２２と、駐車記憶部２３とを有している。走行データ記憶部２１は、センサ部３、入力部４及び自動駐車支援装置５からの出力信号に基づいて、自車両の走行データを時系列に記憶（記録）する。   The ECU 20 includes a travel data storage unit 21, a parking determination unit 22, and a parking storage unit 23. The travel data storage unit 21 stores (records) travel data of the host vehicle in time series based on output signals from the sensor unit 3, the input unit 4, and the automatic parking assistance device 5.

駐車判別部２２は、走行データ記憶部２１に記憶された自車両の走行データに基づいて、自車両が駐車したか否かを判別し、更に自車両が駐車したと判別されたときに、自車両が手動運転及び自動運転のうち何れの方法で駐車動作が行われて駐車に至ったかを判別する。   The parking discriminating unit 22 discriminates whether or not the own vehicle is parked based on the running data of the own vehicle stored in the running data storage unit 21, and further determines that the own vehicle is parked. It is determined whether the vehicle has been parked by manual operation or automatic driving.

駐車記憶部２３は、駐車判別部２２により得られた情報を記憶（記録）する。具体的には、駐車記憶部２３は、自車両が駐車したと判別されたときに、自車両が駐車状態に至る経緯の情報を記憶する。   The parking storage unit 23 stores (records) the information obtained by the parking determination unit 22. Specifically, the parking storage unit 23 stores information on how the host vehicle reaches the parking state when it is determined that the host vehicle is parked.

例えば図６に示すように、まず手動運転により自車両の駐車動作が開始され、駐車目的場所で自車両が停止した後、自動運転スイッチがオンされて自動運転が開始され、自車両が移動することなく、イグニッションスイッチがオフになって駐車が完了した場合には、手動運転による停止から自動運転による停止を経て駐車状態に至った経緯が記憶されることとなる。   For example, as shown in FIG. 6, first, the parking operation of the host vehicle is started by manual driving. After the host vehicle stops at the parking destination, the automatic driving switch is turned on to start the automatic driving, and the host vehicle moves. Instead, when the ignition switch is turned off and the parking is completed, the history of the parking state from the stop by manual operation to the stop by automatic operation is stored.

以上において、ＥＣＵ２０の走行データ記憶部２１及び駐車判別部２２は、車両の駐車状態を判断する判断手段を構成する。同駐車記憶部２３は、判断手段により車両が駐車したと判断されたときに、車両の駐車位置に関する情報を記録する記録手段を構成する。   In the above, the travel data storage unit 21 and the parking determination unit 22 of the ECU 20 constitute a determination unit that determines the parking state of the vehicle. The parking storage unit 23 constitutes a recording unit that records information on the parking position of the vehicle when the determination unit determines that the vehicle is parked.

このように本実施形態においては、例えば自車両の駐車動作完了の直前に手動運転から自動運転に切り換わっても、自動運転による駐車とは判別されずに、手動運転による駐車と判別され、実際の駐車位置が駐車記憶部２３に記憶されることになる。従って、その後で自動駐車支援装置５を利用して自動運転により自車両を駐車する際に、駐車目標位置が自動で設定されるときは、ドライバの嗜好を反映した適切な駐車目標位置が設定されるようになる。   As described above, in this embodiment, for example, even when switching from manual driving to automatic driving immediately before the completion of the parking operation of the host vehicle, it is determined that the parking is based on manual driving, not the parking based on automatic driving. Is stored in the parking storage unit 23. Therefore, when the parking target position is automatically set when the own vehicle is parked by automatic driving using the automatic parking assist device 5 thereafter, an appropriate parking target position reflecting the driver's preference is set. Become so.

図７は、上記第２実施形態の他の変形例の概略を示すブロック図である。同図において、ＥＣＵ２０は、上記の走行データ記憶部２１と、駐車判別部２４と、計算負荷監視部２５と、一時記憶部２６と、情報抽出部２７と、駐車記憶部２８とを有している。   FIG. 7 is a block diagram showing an outline of another modification of the second embodiment. In the same figure, ECU20 has said driving | running | working data storage part 21, the parking discrimination | determination part 24, the calculation load monitoring part 25, the temporary storage part 26, the information extraction part 27, and the parking storage part 28. Yes.

駐車判別部２４は、走行データ記憶部２１に記憶された自車両の走行データに基づいて、自車両が駐車したか否かを判別し、自車両が駐車したと判別されたときに、その旨の信号を計算負荷監視部２５に送出する。   The parking discriminating unit 24 discriminates whether or not the own vehicle is parked based on the running data of the own vehicle stored in the running data storage unit 21. Is sent to the calculation load monitoring unit 25.

計算負荷監視部２５は、駐車判別部２４から自車両が駐車したと判別された旨の信号を受けたときに、センサ部３、入力部４及び自動駐車支援装置５からの出力信号に基づいて、自車両の計算負荷を監視し、その結果を一時記憶部２６に送出する。一時記憶部２６は、計算負荷監視部２５により自車両の計算負荷が所定値よりも軽くなったと判断されたときに、走行データ記憶部２１に記憶されたデータの一部を記憶する。   When the calculation load monitoring unit 25 receives a signal indicating that the host vehicle is parked from the parking determination unit 24, the calculation load monitoring unit 25 is based on output signals from the sensor unit 3, the input unit 4, and the automatic parking assistance device 5. The calculation load of the host vehicle is monitored and the result is sent to the temporary storage unit 26. The temporary storage unit 26 stores a part of the data stored in the travel data storage unit 21 when the calculation load monitoring unit 25 determines that the calculation load of the host vehicle has become lighter than a predetermined value.

情報抽出部２７は、一時記憶部２６に記憶されたデータに基づいて、自車両が手動運転及び自動運転のうち何れの方法で駐車動作が行われたかを判別する。駐車記憶部２８は、情報抽出部２７により得られた情報を記憶する。   Based on the data stored in the temporary storage unit 26, the information extraction unit 27 determines whether the own vehicle has been parked by manual driving or automatic driving.
