Description

本発明は車両の空気抵抗低減装置に係り、詳しくはトレーラ牽引の有無と荷箱高さを判定して、ルーフディフレクタの最適位置を自動的に調整する機能を備えた車両の空気抵抗低減装置に関する。   The present invention relates to a vehicle air resistance reduction device, and more particularly, to a vehicle air resistance reduction device having a function of automatically adjusting an optimum position of a roof deflector by determining the presence or absence of trailer towing and the height of a cargo box. .

従来、トラックには、キャビンルーフよりも荷箱が高くなっている場合が多く、空気抵抗が増加する。
このため、多くのトラックには、空気抵抗を低減するためにルーフディフレクタ（導風板）と呼ばれる装置がキャビンルーフに装着されている。
しかし乍ら、トラックには、荷箱を積載したトレーラを牽引するトラクタのように、トレーラを牽引した状態だけでなく、トレーラを牽引しないで走行する頻度が多いものもある。 Conventionally, trucks often have a higher packing box than a cabin roof, increasing air resistance.
For this reason, in many trucks, a device called a roof deflector (wind guide plate) is mounted on the cabin roof in order to reduce air resistance.
However, some trucks not only pull the trailer but also frequently travel without towing the trailer, such as a tractor that pulls the trailer loaded with a packing box.

而して、斯様にトレーラを牽引しない場合、ルーフディフレクタを装着したままだと、ルーフディフレクタを装着しない場合に比べて空気抵抗が増大し、また、荷箱の高さには様々なサイズのものがあり、荷箱の高さとルーフディフレクタの高さが合わない場合にも、空気抵抗が増加してしまう。
そこで、斯かる課題を解決する方法として、特許文献１及び特許文献２に開示された空気抵抗低減装置が知られている。 Thus, when the trailer is not pulled in this way, the air resistance increases when the roof deflector is not installed, compared to the case where the roof deflector is not installed, and the height of the packing box has various sizes. Even if there is something and the height of the packing box and the height of the roof deflector do not match, the air resistance will increase.
Therefore, as a method for solving such a problem, an air resistance reduction device disclosed in Patent Literature 1 and Patent Literature 2 is known.

特許文献１及び特許文献２に開示されたこれらの空気抵抗低減装置は、いずれもトレーラの荷箱高さとトレーラ牽引の有無でルーフディフレクタの高さを調整しており、効果的に空気抵抗の低減が図られている。
特開平８−２３０７２６号公報 特開２００３−１９１８７３号公報 These air resistance reduction devices disclosed in Patent Document 1 and Patent Document 2 both adjust the height of the roof deflector by adjusting the height of the trailer's packing box and the trailer towing, and effectively reducing the air resistance. Is planned.

しかし、特許文献１，２の従来例にあっては、トレーラ牽引の有無や荷箱の高さをドライバーが目視で確認，調整しなければならず、荷箱の高さに応じた正確な効果を期待することが難しいという課題が残されていた。
本発明は斯かる実情に鑑み案出されたもので、トレーラ牽引の有無や荷箱の高さを判定してルーフディフレクタの最適位置を自動的に調整可能とすることで、適確な空気抵抗の低減を図った車両の空気抵抗低減装置を提供することを目的とする。 However, in the conventional examples of Patent Documents 1 and 2, the driver must visually check and adjust the presence or absence of trailer towing and the height of the packing box, and an accurate effect according to the height of the packing box. The problem that it was difficult to expect was left.
The present invention has been devised in view of such circumstances, and it is possible to automatically adjust the optimum position of the roof deflector by determining the presence / absence of trailer towing and the height of the packing box. An object of the present invention is to provide a vehicle air resistance reduction device that reduces the above-mentioned problem.

斯かる目的を達成するため、請求項１に係る車両の空気抵抗低減装置は、トレーラとの連結部のカプラに装着され、トレーラ牽引の有無を検出するカプラセンサーと、車両ルーフに前端が回動可能に支持された可動式のルーフディフレクタと、当該ルーフディフレクタを回動させる回動手段と、車両ルーフに装着され、可動式の前記ルーフディフレクタの後端と車両ルーフ間の距離を測定する第一のレーザー距離計と、車両ルーフに装着され、トレーラに積載された荷箱までの距離と荷箱の上部角部までの仰角を測定する第二のレーザー距離計と、前記センサーの検出信号と第一，第二のレーザー距離計の測定信号を入力する制御手段とを備え、前記制御手段は、センサーの検出信号と、入力した両レーザー距離計の測定信号を基に前記回動手段を駆動制御して、トレーラ牽引の有無及び荷箱の高さに応じ、ルーフディフレクタの後端の最適位置を自動調整することを特徴とする。 In order to achieve such an object, a vehicle air resistance reduction device according to claim 1 is mounted on a coupler in a connecting portion with a trailer, a coupler sensor for detecting the presence or absence of trailer pulling, and a front end of the vehicle roof rotating. A movable roof deflector supported in a movable manner, a rotating means for rotating the roof deflector, and a first mounted on the vehicle roof and measuring a distance between the rear end of the movable roof deflector and the vehicle roof. A laser rangefinder, a second laser rangefinder that measures the distance to the cargo box mounted on the trailer and loaded on the trailer and the elevation angle to the upper corner of the cargo box, and the detection signal of the sensor and the first one, and control means for entering the measurement signal of the second laser rangefinders, the control means, the rotation detection signal of the sensor, the measurement signals of both laser rangefinders that enter the group Drives and controls the stage, depending on the presence and the packing box height of trailer towing, characterized by automatically adjusting the optimum position of the rear end of the roof deflector.

そして、請求項２に係る発明は、請求項１に記載の車両の空気抵抗低減装置に於て、前記回動手段は、前端が車両ルーフに回動可能に取り付くルーフディフレクタの後端側と車両ルーフとの間に装着されたエアシリンダと、当該エアシリンダに配管を介して接続されたエアタンクと、当該配管中に装着され、エアを大気へ放出する第一の電磁弁とエアタンクからのエアの流入を制御する第二の電磁弁とからなることを特徴とする。   According to a second aspect of the present invention, in the vehicle air resistance reducing device according to the first aspect, the rotating means includes a rear end side of a roof deflector whose front end is rotatably attached to the vehicle roof, and the vehicle. An air cylinder mounted between the roof, an air tank connected to the air cylinder via a pipe, a first solenoid valve mounted in the pipe and releasing air to the atmosphere, and air from the air tank And a second solenoid valve for controlling inflow.

請求項１に係る発明によれば、トレーラ牽引の有無や荷箱の高さに応じ、ルーフディフレクタの後端の高さ（最適位置）を自動的に調整できるので、トレーラ牽引の有無や荷箱の高さをドライバーが目視で確認，調整しなければならない従来例に比し、トレーラ牽引の有無や荷箱の高さに応じた正確なルーフディフレクタ後端の高さの自動調整が可能となり、この結果、荷箱やルーフディフレクタの空気抵抗をより効果的に低減して燃費の向上が図れる利点を有する。 According to the first aspect of the present invention, the height (optimum position) of the rear end of the roof deflector can be automatically adjusted according to the presence / absence of trailer towing and the height of the packing box. Compared to conventional examples where the driver must visually check and adjust the height of the roof, it is possible to automatically adjust the height of the rear end of the roof deflector according to the presence of trailer towing and the height of the packing box, As a result, there is an advantage that the air resistance of the packing box and the roof deflector can be more effectively reduced to improve fuel efficiency.

そして、請求項２に係る発明によれば、トラクタに標準搭載されるエアタンクを使用するため、コストが嵩むこともない。 In the invention according to claim 2, for use air tank tractor Ru standard with, it is not also increase costs.

以下、本発明の実施形態を図面に基づいて詳細に説明する。
図１は請求項１及び請求項２の一実施形態に係る車両の空気抵抗低減装置を示し、図中、１は荷箱３を積載したトレーラ５を牽引するトラクタ（セミトラクタ）で、トラクタ１には図示しないカプラが装着されており、カプラはその上面を形成するカプラベースでトレーラ５を支持し、カプラベース中央下部に装着したジョー機構でトレーラ５のキングピンと結合して、牽引力や制動力等をトレーラ５側に伝達している。 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 shows a vehicle air resistance reducing device according to an embodiment of claims 1 and 2. In the figure, reference numeral 1 denotes a tractor (semi-tractor) that pulls a trailer 5 loaded with a cargo box 3. A coupler (not shown) is mounted on the coupler, and the coupler supports the trailer 5 with a coupler base that forms the upper surface of the coupler, and is coupled to the king pin of the trailer 5 by a jaw mechanism mounted at the lower center of the coupler base. Etc. are transmitted to the trailer 5 side.

そして、カプラには、従来のトラクタに標準搭載されているカプラセンサー７が装着されており、図２に示すようにカプラセンサー７の検出信号がＥＣＵ（制御手段）９のトレーラ牽引判断部１１に入力されて、トレーラ牽引の有無がこのトレーラ牽引判断部１１で判定されるようになっている。
また、図１に於て、１３はトラクタ１のルーフ１５に装着された可動式のルーフディフレクタで、ルーフディフレクタ１３は前端がヒンジ部材１７を介してルーフ１５の前部側に回動可能に支持されている。そして、ルーフディフレクタ１３の後端側とルーフ１５との間に、ルーフディフレクタ１３の高さを調整するエアシリンダ１９が装着されている。 The coupler is equipped with a coupler sensor 7 which is standardly mounted on a conventional tractor, and a detection signal of the coupler sensor 7 is sent to a trailer traction determination unit 11 of an ECU (control means) 9 as shown in FIG. The trailer tow determination unit 11 determines whether the trailer is towed or not.
In FIG. 1, reference numeral 13 denotes a movable roof deflector mounted on the roof 15 of the tractor 1, and the roof deflector 13 is rotatably supported at the front end of the roof 15 via a hinge member 17. Has been. An air cylinder 19 that adjusts the height of the roof deflector 13 is mounted between the rear end side of the roof deflector 13 and the roof 15.

而して、エアシリンダ１９には配管２１を介してエアタンク２３が接続され、更に、当該配管２１には、エアを大気へ放出する第一の電磁弁２５と、エアタンク２３からのエアの流入を制御する第二の電磁弁２７が装着され、エアシリンダ１９と配管２１，エアタンク２３，電磁弁２５，２７は、トレーラ牽引の有無及び荷箱高さに応じてルーフディフレクタ１３を回動させる回動手段Ａを構成している。   Thus, an air tank 23 is connected to the air cylinder 19 via a pipe 21, and further, a first electromagnetic valve 25 that discharges air to the atmosphere and an inflow of air from the air tank 23 to the pipe 21. A second electromagnetic valve 27 to be controlled is mounted, and the air cylinder 19 and the pipe 21, the air tank 23, and the electromagnetic valves 25 and 27 rotate to rotate the roof deflector 13 according to the presence or absence of trailer towing and the height of the cargo box. Means A are configured.

尚、エアタンク２３は、従来、トレーラ１に標準搭載されているものを使用している。
そして、トレーラ５が牽引されていない場合、図２に示すＥＣＵ９の電磁弁制御判断部２９は、トレーラ牽引判断部１１の判定に基づき電磁弁２７を閉じ、電磁弁２５を開いてエアシリンダ１９のエアを大気に解放してエアシリンダ１９を縮退させ、ルーフディフレクタ１３をルーフ１５上まで下降させるようになっている。 As the air tank 23, a conventional one that is standardly mounted on the trailer 1 is used.
When the trailer 5 is not towed, the electromagnetic valve control determination unit 29 of the ECU 9 shown in FIG. 2 closes the electromagnetic valve 27 and opens the electromagnetic valve 25 based on the determination of the trailer tow determination unit 11 to open the air cylinder 19. The air is released into the atmosphere, the air cylinder 19 is degenerated, and the roof deflector 13 is lowered onto the roof 15.

一方、図１に示すようにルーフ１５の後部側には、可動式のルーフディフレクタ１３の後端とルーフ１５間の距離（Ｈ１）を測定する第一のレーザー距離計３１と、トレーラ５に積載された荷箱３までの距離（Ｘ１）と荷箱３の上部角部３ａまでの仰角（θ）を測定する第二のレーザー距離計３３が装着されており、トレーラ５が牽引されている場合、図２に示すように第一のレーザー距離計３１の測定信号はＥＣＵ９の必要駆動距離演算部３５に入力され、第二のレーザー距離計３３の測定信号はＥＣＵ９の荷箱高さ演算部３７に入力されている。 On the other hand, as shown in FIG. 1, on the rear side of the roof 15, a first laser rangefinder 31 that measures the distance (H 1) between the rear end of the movable roof deflector 13 and the roof 15, and a trailer 5 are loaded. When the trailer 5 is pulled and the second laser distance meter 33 is installed to measure the distance (X1) to the packed box 3 and the elevation angle (θ) to the upper corner 3a of the packed box 3 As shown in FIG. 2, the measurement signal of the first laser distance meter 31 is input to the necessary drive distance calculation unit 35 of the ECU 9, and the measurement signal of the second laser distance meter 33 is input to the packing box height calculation unit 37 of the ECU 9. Has been entered.

そして、荷箱高さ演算部３７は、レーザー距離計３３で測定された距離（Ｘ１）と仰角（θ）から、荷箱高さ（Ｈ２）をＨ２＝Ｘ１×ｔａｎθの計算式で算出して、この算出値を必要駆動距離演算部３５に入力するようになっている。
次いで、必要駆動距離演算部３５では、荷箱高さ演算部３７で算出された荷箱高さ（Ｈ２）と、前記レーザー距離計３１で測定されたルーフディフレクタ１３の後端とルーフ１５間の距離（Ｈ１）から、ルーフディフレクタ１３の後端の必要駆動距離（Ｈ３）をＨ３＝Ｈ２−Ｈ１の計算式で算出する。 Then, the packing box height calculation unit 37 calculates the packing box height (H2) from the distance (X1) measured by the laser distance meter 33 and the elevation angle (θ) by the calculation formula of H2 = X1 × tan θ. The calculated value is input to the required drive distance calculation unit 35.
Next, in the required drive distance calculation unit 35, the packing box height (H2) calculated by the packing box height calculation unit 37, and the rear end of the roof deflector 13 measured by the laser distance meter 31 and the roof 15 are measured. From the distance (H1), the required driving distance (H3) of the rear end of the roof deflector 13 is calculated by the calculation formula of H3 = H2−H1.

そして、電磁弁制御判断部２９は、必要駆動距離（Ｈ３）が正（Ｈ３＞０）の場合、電磁弁２５を閉じ、電磁弁２７を開いてＨ３＝０となるまでエアタンク２３からエアシリンダ１９にエアを供給して、ルーフディフレクタ１３を上昇させるようになっている。
一方、必要駆動距離（Ｈ３）が負（Ｈ３＜０）の場合、電磁弁制御判断部２９は、電磁弁２７を閉じ、電磁弁２５を開いてＨ３＝０となるまでエアシリンダ１９からエアを大気に解放して、ルーフディフレクタ１３を下降させるようになっている。 When the required driving distance (H3) is positive (H3> 0), the solenoid valve control determination unit 29 closes the solenoid valve 25, opens the solenoid valve 27, and until the H3 = 0, the air cylinder 23 to the air cylinder 19 Air is supplied to the roof to raise the roof deflector 13.
On the other hand, when the required drive distance (H3) is negative (H3 <0), the solenoid valve control determination unit 29 closes the solenoid valve 27, opens the solenoid valve 25, and draws air from the air cylinder 19 until H3 = 0. The roof deflector 13 is lowered by being released to the atmosphere.

また、必要駆動距離演算部３５に於て、Ｈ３＝Ｈ２−Ｈ１の計算式で算出されたルーフディフレクタ１３の必要駆動距離（Ｈ３）がＨ３＝０の場合、ルーフディフレクタ１３の高さ調整は不要であるから、電磁弁制御判断部２９は電磁弁２５，２７を作動させないように構成されている。
本実施形態に係る車両の空気抵抗低減装置３９はこのように構成されており、以下、図３のフローチャートに基づきその動作を説明する。 Further, when the required driving distance (H3) of the roof deflector 13 calculated by the calculation formula of H3 = H2−H1 in the required driving distance calculation unit 35 is H3 = 0, the height adjustment of the roof deflector 13 is unnecessary. Therefore, the solenoid valve control determination unit 29 is configured not to operate the solenoid valves 25 and 27.
The vehicle air resistance reducing device 39 according to the present embodiment is configured as described above, and the operation thereof will be described below based on the flowchart of FIG.

トラクタ１がキーＯＮ操作されると、先ず、ステップＳ１に於て、カプラセンサー７の検出信号を基に、ＥＣＵ９のトレーラ牽引判断部１１はトレーラ牽引の有無を判定する。
そして、ステップＳ１でトレーラ５が牽引されていないと判定されると、電磁弁制御判断部２９は、電磁弁２７を閉じ、電磁弁２５を開いてエアシリンダ１９のエアを大気に解放して、ルーフディフレクタ１３をルーフ１５上まで下降させる（ステップＳ２，Ｓ３）。 When the tractor 1 is turned on, first, in step S1, the trailer traction determination unit 11 of the ECU 9 determines the presence or absence of trailer traction based on the detection signal of the coupler sensor 7.
When it is determined in step S1 that the trailer 5 is not pulled, the solenoid valve control determination unit 29 closes the solenoid valve 27, opens the solenoid valve 25, and releases the air in the air cylinder 19 to the atmosphere. The roof deflector 13 is lowered onto the roof 15 (steps S2 and S3).

この結果、トレーラ５を牽引しないトラクタ１の走行時に、ルーフディフレクタ１３による空気抵抗が軽減することとなる。
一方、ステップＳ１でトレーラ５が牽引されていると判定されると、ステップＳ４に進み、レーザー距離計３１でルーフディフレクタ１３の後端とルーフ１５間の距離（Ｈ１）が測定されて、その測定信号が必要駆動距離演算部３５に入力されると共に、ステップＳ５で荷箱３までの距離（Ｘ１）と荷箱３の上部角部３ａまでの仰角（θ）がレーザー距離計３３で測定されて、その測定信号が荷箱高さ演算部３７に入力される。 As a result, air resistance by the roof deflector 13 is reduced when the tractor 1 that does not pull the trailer 5 is traveling.
On the other hand, if it is determined in step S1 that the trailer 5 is being pulled, the process proceeds to step S4, where the laser distance meter 31 measures the distance (H1) between the rear end of the roof deflector 13 and the roof 15, and the measurement. A signal is input to the required drive distance calculation unit 35, and the distance (X1) to the cargo box 3 and the elevation angle (θ) to the upper corner 3a of the cargo box 3 are measured by the laser distance meter 33 in step S5. The measurement signal is input to the packing box height calculation unit 37.

そして、ステップＳ６に於て、荷箱高さ演算部３７は、レーザー距離計３３で測定された距離（Ｘ１）と仰角（θ）から荷箱高さ（Ｈ２）を前記計算式で算出して、この算出値を必要駆動距離演算部３５に入力する。
すると、ステップＳ７で必要駆動距離演算部３５は、算出された前記荷箱高さ（Ｈ２）とレーザー距離計３１で測定された距離（Ｈ１）から、ルーフディフレクタ１３の後端の必要駆動距離（Ｈ３）を前記計算式で算出する。 In step S6, the packing box height calculation unit 37 calculates the packing box height (H2) from the distance (X1) measured by the laser distance meter 33 and the elevation angle (θ) using the above formula. The calculated value is input to the required drive distance calculation unit 35.
Then, in step S7, the required drive distance calculation unit 35 calculates the required drive distance (at the rear end of the roof deflector 13) from the calculated height (H2) of the packing box and the distance (H1) measured by the laser distance meter 31. H3) is calculated by the above formula.

そして、必要駆動距離（Ｈ３）が正（Ｈ３＞０）の場合、電磁弁制御判断部２９は、電磁弁２５を閉じ、電磁弁２７を開いてＨ３＝０となるまでエアタンク２３からエアシリンダ１９にエアを供給してルーフディフレクタ１３を上昇させ（ステップＳ８，Ｓ９）、この後、ステップＳ１に戻ることとなる。
一方、必要駆動距離（Ｈ３）が負（Ｈ３＜０）の場合、電磁弁制御判断部２９は、電磁弁２７を閉じ、電磁弁２５を開いてＨ３＝０となるまでエアシリンダ１９からエアを大気に解放してルーフディフレクタ１３を下降させ（ステップＳ１０，Ｓ１１）、この後、ステップＳ１に戻る。 When the required driving distance (H3) is positive (H3> 0), the solenoid valve control determination unit 29 closes the solenoid valve 25 and opens the solenoid valve 27 until the H3 = 0 until the air cylinder 23 reaches the air cylinder 19. Air is supplied to the roof deflector 13 to raise it (steps S8 and S9), and then the process returns to step S1.
On the other hand, when the required drive distance (H3) is negative (H3 <0), the solenoid valve control determination unit 29 closes the solenoid valve 27, opens the solenoid valve 25, and draws air from the air cylinder 19 until H3 = 0. The roof deflector 13 is lowered by being released to the atmosphere (steps S10 and S11), and then the process returns to step S1.

また、ステップＳ７でＨ３＝０と判定された場合、ルーフディフレクタ１３の高さ調整は不要であるから、電磁弁制御判断部２９は両電磁弁２５，２７を閉じてルーフディフレクタ１３を作動させずに（ステップＳ１２，Ｓ１３）、ステップＳ１に戻る。
このように本実施形態に係る空気抵抗低減装置３９は、トレーラ牽引の有無や荷箱３の高さに応じ、ルーフディフレクタ１３の後端の高さ（最適位置）を自動的に調整可能としたので、トレーラ牽引の有無や荷箱の高さをドライバーが目視で確認，調整しなければならない特許文献１，２の従来例に比し、トレーラ牽引の有無や荷箱３の高さに応じた正確なルーフディフレクタ１３後端の高さの自動調整が可能となり、この結果、荷箱３やルーフディフレクタ１３の空気抵抗をより効果的に低減して燃費の向上が図れる利点を有する。 If it is determined in step S7 that H3 = 0, it is not necessary to adjust the height of the roof deflector 13. Therefore, the solenoid valve control determination unit 29 does not operate the roof deflector 13 by closing both the solenoid valves 25 and 27. (Steps S12 and S13), the process returns to Step S1.
As described above, the air resistance reduction device 39 according to the present embodiment can automatically adjust the height (optimum position) of the rear end of the roof deflector 13 according to the presence or absence of trailer towing and the height of the cargo box 3. Therefore, compared to the conventional examples of Patent Documents 1 and 2 where the driver must visually check and adjust the trailer towing and the height of the packing box, it depends on the presence of trailer towing and the height of the packing box 3 Accurate automatic adjustment of the height of the rear end of the roof deflector 13 is possible. As a result, there is an advantage that the air resistance of the cargo box 3 and the roof deflector 13 can be more effectively reduced and fuel consumption can be improved.

而も、本実施形態に係る空気抵抗低減装置３９は、通常のトラクタに標準搭載されるカプラセンサー７やエアタンク２３等の既存のものを使用するため、大幅にコストが嵩むこともない。
また、本実施形態によれば、荷箱３の高さを測定することができるため、ナビゲーションシステムと組み合わせることによって、高さ制限のないルートの情報提供、もしくは警告をドライバーに促すことが可能である。 In addition, since the air resistance reduction device 39 according to the present embodiment uses existing ones such as the coupler sensor 7 and the air tank 23 that are standardly mounted on a normal tractor, the cost does not increase significantly.
In addition, according to the present embodiment, the height of the packing box 3 can be measured, and by combining with the navigation system, it is possible to prompt the driver to provide information on a route with no height restriction or to warn the driver. is there.
