| Abstract(J) | 実車走行中のタイヤ接地力を推定するため、タイヤ内に超小型カメラを埋め込み、内面の接地形状変化を計測することを試みた。本講演では，計測システムの概要，台上試験による内面変形と接地力の精度検証結果，および実車試験における接地形状変化・接地力推定結果をもとにした車両特性差の計測事例について報告する． Translation |
| Abstract(E) | In order not to change the vehicle characteristic due to sensors such as wheel force sensor, we tried to estimate the contact forces by embedding an ultra-small camera inside the tire and measuring the change in the contact shape of the tire inner surface. We conducted a bench test to verify accuracy, and confirmed that the relationship between inner surface deformation and contact forces can be linearly approximated. In addition, we introduce the vehicle test example that evaluates the dynamic performance of two test vehicles with different specification. |
