【発明の詳細な説明】
本発明は車高調整手段を備える車両において、
灯器類の光軸を常に適正に維持するための光軸修
正方式に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention provides a vehicle equipped with vehicle height adjustment means,
This invention relates to an optical axis correction method for always properly maintaining the optical axis of lighting equipment.
車両（自動車）の高速走行時における走行抵抗
は急激に増大する空気抵抗が大部分を占め走行に
必要なエネルギのほとんどがこれにより消耗す
る。この為車両の走行性能、燃費等を向上させる
べく空力特性を改善する努力がなされているが、
この一つとして低速走行時と高速走行時とにおい
て車両の姿勢を変えることにより操安性及び乗心
地性の維持とともに空気抵抗の減少により空力特
性を改善することができる。 When a vehicle (automobile) runs at high speed, most of the running resistance is due to rapidly increasing air resistance, which consumes most of the energy required for running. For this reason, efforts are being made to improve the aerodynamic characteristics of vehicles in order to improve their driving performance, fuel efficiency, etc.
One example of this is that by changing the attitude of the vehicle between running at low speeds and running at high speeds, it is possible to maintain steering stability and ride comfort, and to improve aerodynamic characteristics by reducing air resistance.
この姿勢の変更は車両に備える車高調整手段に
よつて行うことができ、第４図は斯かる車高調整
手段により車高調整を行つた場合を明示する車両
の側面図である。同図に於て実線で示す車両C0
は低速走行時の状態を示し、又二点鎖線で示す車
両C1は高速走行時の状態を示すもので高速走行
時に於ては車両を前下がり（後上がり）の姿勢に
する。 This attitude change can be performed by a vehicle height adjustment means provided in the vehicle, and FIG. 4 is a side view of the vehicle clearly showing the case where the vehicle height is adjusted by such vehicle height adjustment means. Vehicle C 0 shown by the solid line in the figure
indicates the state when the vehicle is running at low speed, and the vehicle C1 indicated by a chain double-dashed line indicates the state when running at high speed, and when running at high speed, the vehicle is in a forward-downward (rearward-upward) posture.
ところが、走行中に於てこのような車両姿勢を

高速走行時を基準とし、この状態でヘツドライト
Ｈの光軸をL10に修正して正規の光軸角を維持し、
規定の照射特性を得ている状態を想定した場合に
於て、このままの状態から低速走行へ移行し、車
高調整によつて前上がりの状態（車両C0）にし
た場合には光軸L2は上側へ向き対向者の運転者
等に眩惑を与え、この場合にも規定の照射特性を
得られなくなる不具合を生ずる。 However, when the vehicle posture is changed while the vehicle is running, the vertical angle of the optical axis of the headlights and other lighting equipment also shifts, resulting in the following problems. That is, as is clear from Fig. 4, when driving at low speed, the optical axis of the headlight H becomes L0 , maintaining the normal optical axis angle with respect to the road surface R, and obtaining the specified irradiation characteristics. If you move to high speed driving with the current position and adjust the vehicle height to lower the front (vehicle C 1 ), the optical axis L 1 will point downward and the amount of illumination in the front will be insufficient.
Specified irradiation characteristics cannot be obtained. In addition, using this high-speed driving as a reference, in this state, the optical axis of the headlight H is corrected to L 10 to maintain the normal optical axis angle,
Assuming that the specified irradiation characteristics are obtained, if you shift from this state to low-speed driving and raise the front of the vehicle (vehicle C 0 ) by adjusting the vehicle height, the optical axis L 2 faces upward and dazzles oncoming drivers, and in this case as well, a problem arises in that the specified illumination characteristics cannot be obtained.
したがつて、車高調整を行う場合にはこれと連
動的にヘツドライトＨの光軸を修正する必要があ

体の姿勢角変化は一様でないためヘツドライトの
光軸修正を車高調整の期間中常に適正な方向に保
持することは簡易な連動による修正手段では困難
である。 Therefore, when adjusting the vehicle height, it is necessary to adjust the optical axis of the headlight H in conjunction with the adjustment. However, the vehicle height adjustment control time or the change in the vehicle body attitude angle during the adjustment period is not uniform, depending on conditions such as the number of passengers, the weight of luggage, and the loading position. It is difficult to maintain the optical axis of the headlight in the correct direction during vehicle height adjustment using simple interlocking correction means.
一方、光軸修正に於て、光軸が下側へ向くより
上側へ向く方が前述の如くその弊害は重大であ
り、修正時に於て光軸が上側へ向いてしまうこと
は確実に阻止しなければならない。 On the other hand, when correcting the optical axis, as mentioned above, the disadvantage is more serious if the optical axis points upwards rather than downwards, and it is necessary to reliably prevent the optical axis from turning upwards during corrections. There must be.

The actuator 7 is constituted by an electric means such as a motor or a solenoid, or a driving means using hydraulic pressure or pneumatic pressure, and controls the vertical movement of the rod 6 by a headlight control signal S2 input thereto. Further, the actuator 7 is connected to a control signal generator 8 . This generator 8 is configured with a predetermined electrical circuit, and is connected to a vehicle height adjusting means (not shown) to input a predetermined attitude angle control signal S1 .
The control signal S2 is generated and output according to a predetermined timing based on the method of the present invention. Note that the actuator 7 and the control signal generating section 8 constitute a control means 9.

２の光軸はL0となつている。 First, assume that the vehicle is running at normal low speed. In this case, the headlight device 1 in FIG. 1 is in the position shown by the solid line, and the optical axis of the headlight 2 is L0 .

As shown in FIG. 4, the vehicle height is lowered forward (vehicle C 1 ) by the vehicle height adjusting means. The specific operation of the vehicle height adjusting means is performed by, for example, reducing the air pressure of the suspension unit that supports the wheels using a predetermined attitude angle control signal S1-1 .
よつて、ヘツドライト２の光軸はL1と下向き

等により車高調整時間が比較的長くなつた場合に
於ても光軸はL0より上向きになることはない。 Therefore, the optical axis of the headlight 2 is directed downward at L1 , but the optical axis L1 is corrected to the position L0 by the operation of the control means 9. That is, as shown in Figure 2,
The attitude angle control signal S 1-1 used in the vehicle height adjustment means is supplied to the control signal generator 8, and the attitude angle control signal S 1-1 is supplied to the control signal generator 8.
The headlight control signal S2-1 is immediately output upon detecting that the current has become zero. This control signal S 2-1 is supplied to the actuator 7, and the rod 6 moves downward based on this control signal S 2-1 . As a result, the optical axis is shifted to L 1
is corrected from the position to the L 0 position. in this case,
The control signal S 2-1 is output after the adjustment of the vehicle height to the forward lowering state by the attitude angle control signal S 1-1 is substantially completed. Therefore, even if the vehicle height adjustment time becomes relatively long due to vehicle height, loading conditions, etc., the optical axis will not be directed upwards from L0 .
一方、車両が斯かる高速走行から低速走行に移
行した場合について想定する。この場合には車高

角制御信号S1-2により制御される。 On the other hand, assume that the vehicle shifts from such high-speed running to low-speed running. In this case, the vehicle height is adjusted by the vehicle height adjustment means to a forward raised state (vehicle C 0 in FIG. 4). In this case, as described above, this is carried out by, for example, increasing the air pressure of the suspension unit, and at this time it is controlled by a predetermined attitude angle control signal S1-2 .
よつて、ヘツドライト２の光軸はL0の位置か

号S1-2とほとんど同時に出力する。即ち、姿勢角
制御信号S1-2が制御信号発生部８に供給された場
合、直ちにヘツドライト制御信号S2-2を生成し出

L0より上向きにはならない。このように、制御
信号S2-2は姿勢角制御信号S1-2により車高を前上
がりに調整を開始すると略同時に出力されること
になる。 Therefore, the optical axis of the headlight 2 is corrected from the L 0 position to the L 2 position, but as shown in FIG. 3, the headlight control signal S 2-2 is almost the same as the attitude angle control signal S 1-2 . Output simultaneously. That is, when the attitude angle control signal S 1-2 is supplied to the control signal generator 8, the headlight control signal S 2-2 is immediately generated and output. This control signal S 2-2 is supplied to the actuator 7, and the rod 6 moves upward based on this control signal S 2-2 . However, at the same time, the vehicle height is lowered forward due to the vehicle height adjustment, so the optical axis is always
It cannot go higher than L 0 . In this way, the control signal S 2-2 is output approximately at the same time as the attitude angle control signal S 1-2 starts adjusting the vehicle height forward.
なお、車高調整がいかなる条件下で行われてい

成される。 Note that the control time based on the control signal S 2-2 is selected so that the optical axis does not go above L 0 no matter what conditions the vehicle height adjustment is performed. Also, Figures 2 and 3 show the timing relationship of each control signal, and the actual control signal is generated by, for example, inverting the polarity of the control signals S 2-1 and S 2-2 . Ru.
以上の実施例に於て、車高を前下がりに調整し

してもよい。 In the above embodiment, when the vehicle height is adjusted to lower the front, the headlight control signal S 2-1 is output immediately after the attitude angle control signal S 1-1 , and when the vehicle height is adjusted to the front higher. The headlight control signal S2-2 is output at the same time as the attitude control signal S1-2 , but unless the optical axis of the headlight is above the specified optical axis L0 , the timing of each signal should be set slightly earlier or later. You can.
なお、姿勢角制御信号はヘツドライトの光軸制
