| 要旨 | Due to increased environmental awareness, "quiet vehicles" such as hybrid cars are driving the market and quietness is increasingly being demanded of column type electric power steering (C-EPS) systems. At the same time, increasing market globalization requires dealing with a wide variety of rough road conditions, which are frequently observed in emerging countries. In this paper, the causes of rattle noise in C-EPS manual steering (MS) gears will be touched on and a quantitative method of evaluating such noise generation proposed. Utilizing a neural network as a means of predicting rattle noise has made it possible to design an MS gear optimally suitable for the vehicle. |
