Abstract
Description
操作端末5は通信機を備え、駐車制御装置100、情報サーバ3と情報の授受が可能である。操作端末5は、通信ネットワークを介して、車外の操作者から操作端末5に入力された操作情報を駐車制御装置100へ送信し、操作情報を駐車制御装置100に入力させる。操作端末5は、固有の識別記号を含めた信号を用いて、駐車制御装置100と交信する。操作端末5は、送受信する通信電波の周波数、駐車制御装置100の通信装置21との通信の確立及び通信の途絶を検知する。
本実施形態の駐車制御装置100は、操舵操作、アクセル・ブレーキ操作が自動的に行われる自動制御タイプであってもよい。駐車制御装置100は、操舵操作を自動で行い、アクセル・ブレーキ操作をドライバが行う半自動タイプであってもよい。本実施形態の駐車制御プログラムでは、操作者が目標駐車スペースを任意に選択してもよいし、駐車制御装置100又は駐車設備側が目標駐車スペースを自動的に設定してもよい。
測距装置2は、カメラ1a~1dと同じ位置に設けてもよいし、異なる位置に設けてもよい。測距装置2は、ミリ波レーダー、レーザーレーダー、超音波レーダーなどのレーダー装置又はソナーを用いることができる。測距装置2は、レーダー装置の受信信号に基づいて物体の存否、物体の位置、物体の大きさ、物体までの距離を検出する。物体は、車両Vの周囲の設置物、歩行者、他車両、駐車車両等を含む。この受信信号は、駐車スペースが空いているか否か(駐車中か否か)の判断に用いられる。なお、障害物の検出は、カメラ1a~1dによるモーションステレオの技術を用いて行ってもよい。
図3に示すように、第1通信系統は短距離無線通信、近距離無線通信を用いることができる。第1通信系統の通信可能距離は10~20m、数十m程度である。短距離無線通信は、無線PAN:Wireless Personal Area Network、NFC:Near field radio communication、DSRC:Dedicated Short Range Communications、特定小電力無線、又は微弱無線を含む。近距離無線通信:WPAN(Wireless Near Field Communication)は、Bluetooth(登録商標)、UWB:Ultra Wide Band、又はZigBee(登録商標)を含む。本システムにおいては、第1通信系統としてBluetooth(登録商標)を用いる。
図4Aに示すように、原則として、車外の操作者から操作端末5に入力された操作情報(第1情報)は、第1通信系統を介して車載装置と送受信され、車載装置のカメラ1a~1dの撮像画像(第2情報)、測距装置2の検出情報(第2情報)、制御装置10の判断情報(第2情報)は、第2通信系統を介して操作端末5と送受信される。測距装置2の検出情報は障害物の存在の有無、存在位置などの情報を含む。制御装置10及び操作端末5は、第1通信系統の通信の質が低い場合には、第1通信系統以外の第2通信系統を用いて、操作情報(第1情報)を送受信する。制御装置10及び操作端末5は、第2通信系統の通信の質が低い場合には、第2通信系統以外の第1通信系統を用いて、提示情報(第2情報)を送受信する。
この場合において、第1情報の一部、第2情報の一部を他の通信系統で送受信できる。第2情報の撮像情報を第2通信系統で送受信し、第2情報の測距情報を第3通信系統で送受信してもよい。
制御装置10及び/又は操作端末5は、第1通信系統の通信の質に関する第1評価値が第1閾値未満である場合には、第1情報の少なくとも一部を第1通信系統以外の他の通信系統を介して授受する処理に加えて、操作情報及び/又は提示情報の情報量を低減させる。制御装置10及び/又は操作端末5は、第2通信系統の通信の質に関する第2評価値が第2閾値未満である場合には、第2情報の少なくとも一部を第2通信系統以外の他の通信系統を介して授受する処理に加えて、操作情報及び/又は提示情報の情報量を低減させる。
制御装置10及び/又は操作端末5は、第1通信系統の通信の質に関する第1評価値が第1閾値未満である場合には、第1情報の少なくとも一部を第1通信系統以外の他の通信系統を介して授受する処理に加えて、駐車経路又は駐車経路を移動させる制御命令を変更させる。制御装置10及び/又は操作端末5は、第2通信系統の通信の質に関する第2評価値が第2閾値未満である場合には、第2情報の少なくとも一部を第2通信系統以外の他の通信系統を介して授受する処理に加えて、駐車経路又は駐車経路を移動させる制御命令を変更させる。
ステップ111において、制御装置10は、通信の質に応じて設定されたパラメータを用いて、駐車経路を算出し、算出した駐車経路を車両Vに走行させる制御命令を生成する。
本実施形態の駐車制御装置100は、車両Vが駐車経路に沿って移動するように、制御情報に従い、車両コントローラ70を介して駆動システム40の動作を制御する。
このように、何れか一方の通信系統の通信の質が悪い場合には他の通信系統を用いて通信を行い、さらに、授受する第1情報及び/又は第2情報の情報量を低減するので、通信環境や通信状態が悪くて要求されるレベルよりも通信の質が低い場合であっても、リモート駐車制御を実行(遂行)できる。
通信の質が低いことによって、リモート駐車制御が中止されることを防止できる。この結果、リモート駐車制御機能の信頼性を高めることができる。
何れか一方の通信系統の通信の質が悪い場合には、他の通信系統を用いて通信を行い、さらに、駐車経路の算出時に用いるパラメータ、駐車経路を車両Vに移動させる制御命令の算出処理において用いるパラメータを変更し、異なる駐車経路又は制御命令に基づいて駐車処理を実行するので、通信環境、通信状態が悪く、通信の質が要求されるレベルよりも低い場合であっても、安全が考慮されたリモート駐車制御を実行できる。
通信の質が低いことにより、駐車経路や制御命令に従うことができずに(信頼できずに)リモート駐車制御が中止されることを防止できる。この結果、リモート駐車制御機能の信頼性を高めることができる。
