Sangwook Lee･SangYoung Im･JoonHyuk Kang･TaeNam Jung･JunHyuk Kim･JiHo Choi (HYUNDAI)･KyuWon Cho (Edscha PHA)

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 opening force of electric charge door

YUNGYEOM KIM･joonhyuk kang (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.

Lighting system development for improved efficiency in cargo handling and passenger accessibility

SUNG HO PARK (Hyundai Motor)

As PBVs grow in cargo and passenger transport, nighttime peripheral visibility becomes crucial. Traditional lighting focuses on forward vision or aesthetics, lacking practical illumination for loading and boarding. This study introduces a cost-effective solution considering packaging and optical efficiency. Two systems were developed: Wide Reflector Beam, optimized for optics, structure, and UNECE R-48 compliance; and Wide Line Beam, combining diffusing lenses and GOBO optics to project tailgate paths, ensuring safety and regulatory compliance without extra cooling.

Autonomous driving sensor fusion lamp optical system research

Hyeongseon Kim (Hyundai Motor)

Looking at the trend of autonomous driving sensor installation, sensors that detect medium and long distances are installed on the roof of the vehicle, and sensors that detect short distances are installed in the four corner areas of the vehicle. For reasons such as similarity of location, similarity of function, simultaneous use of angle adjustment and cleaning equipment, it can be said that it is a very useful technology to place autonomous driving sensors inside the headlamp. Against this background, this paper describes the research on installing Lidar sensors, among autonomous driving sensors, inside the lamp.

A Study on the Application of A-SEG Cladding Options

Hyeonggeun Jo (Hyundai Motor)

Introduce how to optionally operate cladding at A-SEG. It can expand the customer's choice and provide high-quality cladding vehicles. Design and Engineering elements to be considered in option application of cladding are presented.

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.
