To enhance profitability through securing cost competitiveness, we aim to develop an economical power tailgate (PTG). The economical type consists of a spindle drive and gas lifter, designed to achieve the dual goals of cost reduction and performance enhancement. In this study, we applied new logic that resolves inconsistencies in the existing logic, ensuring the safety of the PTG and improving its marketability. Furthermore, various experiments were conducted to define adverse environmental conditions and verify the required performance of the PTG. Through this development and research process, we expect to significantly increase profitability by expanding the application of economical PTGs to various vehicle models in the future.

A Study on the Opening Force of a Charging Door

YunGyeom Kim･JoonHyuk Kang･SeokHan Kong (Hyundai Motor)

This paper is a study on the opening force of electric charging doors. According to the recent IQS results, there were complaints regarding the opening force of the electric charging door. I researched the factors influencing the opening force of the electric charging door system and checked the degree of influence of each factor. To reduce the opening force, I conducted a study to optimize the cross section of the sealing and overslam bumper. As the application of electric charging doors will be expanded in the future, it is intended to help set the opening force.

A Study on the Development of Front Radar Cover Technology for Autonomous Vehicles

Juhwan Park･Wanho Son･Gyeomson Seong (SECO Ecoplastic)･Sunghoon Jung (INTOPS)

Smart Cruise Control (SCC) uses radar to detect preceding vehicles, so the SCC cover must protect the sensor while maintaining radar transmittance. If scratches occur on the cover surface, transmittance decreases and the performance and reliability of autonomous driving deteriorate. This study proposes an SCC cover structure that combines a self-healing polyurethane layer capable of recovering surface damage with a design film that provides a three-dimensional appearance. The proposed concept aims to improve scratch durability and exterior quality while enabling a more efficient manufacturing process with reduced time and cost.
