Development of Indoor Lighting Optimization Through Customer Preference Clinic

Daeseon Lee (Hyundai Motor)

As customer demands increase, the design complexity of automobiles increases. Automotive makers have developed design methods using modular architecture method to solve this problem. In this paper, we propose a method to solve design complexity problem using axiom method and matrix visualization method. Axiomatic design is a systems design methodology using design matrix(DM) to analyze the transformation of customer needs into functional requirements, design parameters. We developed the design flow chart using DM(Design Matrix). DSM(Design Structure Matrix), representing linkages of process is also used to reduce the complexity. This approach is applied for vehicle cooling system and show the usefulness of architectural design approach.

Enhanced Telescopic Performance of Stowable Steering Column in Steer-by-Wire System

Herbert Erhardt･Seryas Mohammad･Matthias Beck (Schaeffler Technologies)･Wenshan Tang (Schaeffler Japan)

Advancements in automated driving require stowable steering column for smooth transitions between manual and automated modes. However, the extended axial stroke needed compromises stiffness and NVH performance. This study investigates using preloaded linear bearings to maintain stiffness and NVH levels comparable to conventional steering column system.

Impact Energy Absorption and Safety Evaluation of Glass Fiber Reinforced Plastic Composite Leaf Springs for Automotive Applications

Soo Sik Chung (Hyundai Motor)

Glass fiber reinforced plastic (GFRP) composite leaf springs have gained significant attention as a next-generation automotive component due to their lightweight and durability compared to traditional metal springs. This study evaluated the impact resistance of GFRP leaf springs to confirm their feasibility for real-world vehicle applications, contributing to the development of safer and more efficient vehicles.

A Study on the Multifunctional Protection Bumper Cover of Autonomous Driving Sensor
-Development of Multi-Functional Sensor Cover for EV Grill System Trend-

Hongheui Lee (Hyundai Motor)

This study examined the roles and functions of front bumper and grill components that have recently been changing to implement electric vehicles and autonomous driving. The development of self-healing and device technologies and sensor transmittance maintenance, which require the development of autonomous driving sensors, have been completed as basic technologies.
By removing parting that could not be implemented before, the integrated design and various patterns and colors were implemented to enhance the marketability of the exterior.
It has established standards for self-restoration of heating wires to maintain self-driving sensor performance and endure extreme environments.
