Abstract(J)	オランダのDelft工科大車両研究所では,滑り易い路面条件下に於る非線形タイヤ特性とタイヤと道路との摩擦を評価するため,空気タイヤ軌跡の認識に基づく新しいオンライン評価法を提唱した.前輪懸架に設けた計測器でタイヤ力とモーメントを測り,データベースと比較してタイヤ特性と摩擦を評価するが,キャンバ,力の誤差等により複雑になる. Translation
Abstract(E)	Vehicle control that improves manoeuvrability and thereby safety of vehicles under slippery road conditions requires continuously updated estimates of the non-linear tyre characteristics and the friction between tyre and road. A new on-line estimation method, based on recognition of the pneumatic trail, is proposed. A rather inexpensive measurement system is mounted in the vehicle front wheel suspension that identifies the forces and moments acting on the tyre. In conjunction with a database of previous measurements, tyre characteristics and friction between tyre and road can be estimated. The design of the estimator is complicated by camber, residual forces and moments, combined slip of the tyre and dynamic behaviour of tyre and suspension

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".
