Abstract

PURPOSE:To improve the driving stability under strong gust conditions by constituting such that the resultant wind velocity of natural wind and driving wind is detected by the wind sensor, and based on the detected value the vehicle height reference value is changed and the height control is performed by comparing with the detected vehicle height. CONSTITUTION:The wind velocity is detected by the wind velocity sensor 31 as the resultant wind velocity of the driving wind and natural wind, and is input to the interface 37 of the micro computer 40. The detected vehicle height from the vehicle height sensor 16 is also input to the interface 37. Based on the wind velocity 31 which was input normal height level HN and low height level HL are read out. That is, when the wind velocity is over the preset value, the low height level HL is read out and the solenoid switch valve 10 is operated to become the low height level. That is, by comparing the integrated average value of the detected height over a given time duration and low height level, the vehicle height is controlled by means of the movement of the solenoid valves 10a-10b. Thus, under strong gust, the vehicle height is lowered to improve the stability.

安定性と掃射（性の向上に役立′）。It is well known that the vehicle height has a great effect on the running performance of the vehicle.Therefore, keeping the middle height in the most suitable condition is the best way to improve the running performance of the vehicle.
This will improve stability. In particular, when driving at high speeds or in strong winds, lowering the middle height helps improve vehicle stability and sweeping performance.

It is not possible to adjust the middle and height when driving in strong winds. In addition, in the latter case, the crosswind from high-speed running C will essentially act on the vehicle as wind in the second direction, which has the disadvantage of not being able to accurately detect this with the pipe ((6

させることができる。According to the present invention, by installing a wind speed sensor, for example, at the base of the bridge, the air flow speed generated as the vehicle travels 1j and the natural wind speed are detected. If the average wind speed is higher than the specified fffJ, the vehicle height standard will be changed to the medium convex base!!'-1tf (the medium and high standard value Ht is lower than HH).
Therefore, the vehicle height can be automatically lowered when driving at high speeds or under heavy use, and the stability and maneuverability of the vehicle can be improved.
