車高に保つべく調整動作を行うものである。2. Description of the Related Art Conventionally, it has been proposed that vehicles such as motorcycles and automobiles be equipped with a device for adjusting the height of the vehicle. This vehicle height adjustment device measures the ground clearance of the vehicle body using a vehicle height sensor, sets an appropriate standard vehicle height for the vehicle body's ground clearance in advance, and increases or decreases the number of passengers or loaded cargo relative to this standard vehicle height. When the vehicle height changes, an adjustment operation is performed to always maintain the vehicle height at the reference vehicle height.

とは正常な車高を維持することにはならず、車高調整を
実行させること自体好ましいものではない。In such a vehicle height adjustment device, the front and rear heights of the vehicle body are kept at a constant height when the vehicle is running normally, but on the other hand, when the vehicle is accelerating or decelerating, the front and rear heights of the vehicle body are larger than when the vehicle is running at a steady state. Since the vehicle expands and contracts, detecting vehicle height data during acceleration and deceleration with a sensor and adjusting the vehicle height will not maintain the normal vehicle height, but will cause the vehicle height to be adjusted. That in itself is not desirable.
本発明者は上記の如き問題点に鑑み、これを有効に解決

On the other hand, as input elements, a vehicle height sensor 19 and a vehicle speed sensor 20 constituting means capable of detecting the acceleration/deceleration state of the vehicle are provided. The vehicle height sensor 19 is capable of detecting changes in the ground height of the vehicle body, and the vehicle speed sensor 20 is capable of detecting, for example, the number of rotations of a wheel, and the respective detected information is inputted to the control device 4. Note that the pressure information is manually inputted from the pressure sensor 8 to the control device 4 as described above.
以上の如（構成される車高調整装置は、制御装置４の制
御の下に、下記の如き自動式の車高調整動作を行う。The vehicle height adjustment device configured as described above performs the following automatic vehicle height adjustment operation under the control of the control device 4.

構造については従来から種々のものが提案されている。The automatic vehicle height adjustment is such that when the ground clearance of the vehicle changes due to an increase or decrease in the number of passengers or an increase or decrease in cargo load, the vehicle height sensor 19 detects this change and adjusts the vehicle height to an appropriate height. It is something that is done. The vehicle height sensor 1g is arranged in a vehicle between a vehicle body part corresponding to the upper part of the suspension system and a part corresponding to the lower part of the suspension system, and is configured to extract displacements thereof and detect changes in vehicle height. There is. Various structures of vehicle height sensors have been proposed in the past.

整が行われるものとする。Incidentally, the vehicle height adjustment device described above can perform both manual and automatic vehicle height adjustment, and the selection switch (not shown) can select one of these. With manual vehicle height adjustment, it is possible to separately and selectively adjust the vehicle height of the front fork 13 and rear cushion 150 at the front and rear of the vehicle. It is assumed that adjustment is made only for 15.

ことになる。- When the automatic vehicle height adjustment state is selected, the solenoid valve 12 is first opened and the solenoid pulp 11 is held in the closed state. This makes it possible to adjust only the rear cushion 15 at the rear of the vehicle body. When the solenoid valve 12 opens, the pressure in the gas chamber provided in the catch cushion 15 is measured by the pressure sensor 8, and this pressure information and vehicle height information from the vehicle height sensor 19 are input into the control device 4. Become.
車高センサ１９から出力される信号において、車高状態
が［ＯＫＪのときには車高は適正なものであるとして車
高調整は行われない。In the signal output from the vehicle height sensor 19, when the vehicle height state is [OKJ], it is assumed that the vehicle height is appropriate and no vehicle height adjustment is performed.

気体室から圧縮空気を排気して車高を徐々に低下する。The output signal from the vehicle height sensor 19 is l'-HI GHJ
When , the vehicle height is higher than the standard vehicle height, so the solenoid valve 7 for venting to atmosphere opens intermittently.
Compressed air is exhausted from the gas chamber to gradually lower the vehicle height.

う条件の下に車高調整が行われる。Then, when the vehicle height becomes the reference vehicle height and the output signal of the vehicle height sensor 19 becomes "1 OK", the vehicle height adjustment is stopped. In this case, the pressure in the gas chamber in the rear cushion 15 is reduced, but since a lower limit is set for the gas chamber, if the pressure in the gas chamber does not fall below, for example, 2.0 cm, the vehicle A high adjustment is made.

、気体室の圧力が例えば６．４野より大きくならないと
いう条件の下に車高調整は行われる。Next, the output signal from the vehicle height sensor j9 is l'-LOWJ.
At this time, since the vehicle height is lower than the reference vehicle height, the compressor 2 is activated and high-pressure air is supplied to the gas chamber in the cushion 15, raising the vehicle height. Then, when the vehicle height becomes the reference vehicle height and the output signal of the vehicle height sensor 19 becomes "OK", the vehicle height adjustment is stopped. In this case, the pressure in the gas chamber in the rear cushion 15 is increased, but an upper limit is set for the gas chamber, and under the condition that the pressure in the gas chamber does not exceed, for example, 6.4 degrees. Vehicle height adjustments will be made.
また車高状態が「伸切り」のときには、斯かる状態は一
般に転倒時等に発生するものであるが、一定時間（例え

後に車高調整装置のシステム全体の作動を停止せしめる
如く作動する。In addition, when the vehicle height is at "extended height", such a state generally occurs when the vehicle falls over, but after confirming that the "extended" state has continued for a certain period of time (for example, about 5 seconds), It operates to stop the operation of the entire vehicle height adjustment system.
上記の如く車高セ／す１９の出力信号に基づいて、走行
開始前又は走行中に車両後部の車高が自動的に適正なも
のに調整される。As described above, the vehicle height at the rear of the vehicle is automatically adjusted to an appropriate height before or during travel, based on the output signal from the vehicle height controller 19.

ないようにする。However, when the vehicle accelerates or decelerates as necessary while the vehicle is running, the length of the rear cushion 15 expands or contracts compared to the steady running state, and therefore the vehicle height sensor 19 senses such a state. It may output a signal for vehicle height adjustment. Therefore, the acceleration/deceleration state is detected based on the output signal from the vehicle speed sensor 19, and when the vehicle is running in the acceleration/deceleration state, the vehicle height adjustment as described above is not performed.

て旧車速データとじて使用するく処理２６．２７）。Referring to FIG. 2, a method for detecting acceleration/deceleration states will be explained. First, vehicle height data is input from the vehicle height sensor 19 (process 21). Next, vehicle speed data is input using the vehicle speed sensor 20 (processing 22). As described above, the wheel rotational speed is used as this vehicle speed data, and the rotational speed during a preset certain period of time is measured and input. Regarding this vehicle speed data, the old military speed data obtained in the previous measurement is input into the memory. Next, the new vehicle speed data obtained now is compared with the old vehicle speed data obtained earlier, the difference in wheel rotation speed is essentially taken, and the amount of change in the wheel rotation speed is measured. Whether or not the vehicle is in an acceleration/deceleration state is determined based on whether the amount is larger or smaller than a set value (determination 23). If the amount of change is within the set value, it is assumed that vehicle height sensor 1 is in a normal constant speed driving state.
It is possible to perform vehicle height adjustment based on the vehicle height data input from 9 (processing 24). On the other hand, if the amount of change is greater than the set value, it is assumed that the vehicle is in an acceleration/deceleration state and data processing of the vehicle height data is prohibited. Then, the vehicle height adjustment operation is not performed (process 25). Note that before the process 24.25, the new vehicle speed data is stored in the memory and used as the old vehicle speed data in the next process determination (process 26.27).
以」二の作用によって車両が、加減速状態で走行中には
上記の如き自動式の車高調整は行われず、不必要な車高
調整を除去して正常な車高を維持することができる。Due to the above two effects, automatic vehicle height adjustment as described above is not performed while the vehicle is running under acceleration or deceleration conditions, and unnecessary vehicle height adjustment can be eliminated to maintain a normal vehicle height. .
上記実施例では、車両後部側の車高調整について述べた
が、これに限定されるものではなく、本発明は車高調整
システム一般に適用できるものである。In the above embodiment, vehicle height adjustment on the rear side of the vehicle has been described, but the present invention is not limited to this, and the present invention can be applied to vehicle height adjustment systems in general.

な車高を維持することが可能となる。As is clear from the above explanation, according to the present invention, the automatic vehicle height adjustment device does not perform vehicle height adjustment when the vehicle is in an acceleration state or deceleration state, so that inaccurate vehicle height data is generated. Based on this (vehicle height adjustment can be prohibited and the normal vehicle height can always be maintained).
