Abstract(E)	Suspension settings generally are a compromise for performance on different road roughness and stability requirements. With a priori information of the road roughness a superior performance can be achieved, and this information can be obtained from vehicle based road classification methods that use axle acceleration signals. This paper discusses investigations into effects of vehicle parameters on axle acceleration signals using simulations with a quarter car model on several measured road profiles and presents influences of driving speed. Experimental results from a vehicle with adjustable dampers confirm that the effects of tyre dynamics are larger on rough roads, and due to tyre dynamics the speed relation for axle accelerations depends on road roughness. Additionally the suspension damping and tyre inflation pressure need to be considered.

About search

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.

Search tips

When searching by author name, enter the first and last name separated by a space, such as "Taro Jidosha".
