Abstract(J)車体Roll速度feedbackによるskyhook制御では遅れによる振動増大周波数帯が発生する。そこでWheelbaseと車速の関係によりRoll方向の路面入力が小さくなる周波数を利用して制御遅れによる振動を低減するため,平面運動の連成を考慮した計算予測と制御filter設計を行い,実験によって有効性を検証した。

Translation

Abstract(E)In the skyhook control based on the roll velocity feedback, a vibration increasing frequency band occurs due to the control delay.
To reduce that vibration, we used the wheelbase filtering frequency at which roll oscillation due to road inputs decreases.
Therefore, we designed signal filters with calculation considering roll-lateral coupled motions and experimented with actual vehicle.

How to use the search box

You can enter up to 5 search conditions. The number of search boxes can be increased or decreased with the "+" and "-" buttons on the right.
If you enter multiple words separated by spaces in one search box, the data that "contains all" of the entered words will be searched (AND search).
Example) X (space) Y → "X and Y (including)"

How to use "AND" and "OR" pull-down

If "AND" is specified, the "contains both" data of the phrase entered in the previous and next search boxes will be searched. If you specify "OR", the data that "contains" any of the words entered in the search boxes before and after is searched.
Example) X AND Y → "X and Y (including)"  X OR Z → "X or Z (including)"
If AND and OR searches are mixed, OR search has priority.
Example) X AND Y OR Z → X AND (Y OR Z)
If AND search and multiple OR search are mixed, OR search has priority.
Example) W AND X OR Y OR Z → W AND (X OR Y OR Z)

How to use the search filters

Use the "search filters" when you want to narrow down the search results, such as when there are too many search results. If you check each item, the search results will be narrowed down to only the data that includes that item.
The number in "()" after each item is the number of data that includes that item.
