Study of HILS Development for Vehicle Automation Test using Robots, Motors

Hojin Jy･Soyun Lee･Dan Kim (Hyundai AutoEver)

Since automatic control of some switches is required to perform testing of vehicle ECUs, this paper introduce a case of HILS construction using robots.
NFC tagging for digital keys such as mobile phones or card keys is required to perform automation testing of digital key functions for vehicle entry/start.
In order to build an HILS environment, it is necessary to tag a real digital key to a door handle or a wireless charger, and at this time, HILS can be built using a collaborative robot.
In addition, this paper covers case of HILS construction applied to vehicle remote key input control and multifunction switch control.

In order to build an e-LSD HILS environment, the actual load of the vehicle is required.

This paper introduces a case of HILS construction using a load simulation test bench.

Development of Seat Comfort Evaluation Based on Virtual Human Models

Baekhee Lee (Hyundai Motor)･Byoung-Keon Daniel Park (University of Michigan Transportation Research Institute)

This study focuses on developing a digitalization technique for seat comfort evaluation using virtual human models. Traditional seat comfort evaluations have relied on direct user surveys, but with the advancement of virtual evaluation techniques, digitalization offers improved efficiency and accuracy. The study introduces methods such as seat fitting sentiment prediction and virtual body pressure-based comfort prediction. By utilizing machine learning and virtual simulations, the system achieves high predictive accuracy for seat comfort. Additionally, the study presents a comprehensive system that allows for efficient evaluation of multiple seats and human models. This research contributes to the field of seat comfort evaluation by enhancing digitalization and providing more precise and efficient assessments.

Evaluation Study on the Optimal Implementation Conditions of Indoor Lighting Considering Customer Psychological/Physiological Responses

Daeseon Lee･Cheol Min Park (Hyundai Motor)

With the introduction of autonomous driving, the degree of freedom of indoor drivers in the interior of a car is increasing.Therefore, since indoor customers can engage in various activities such as rest, reading, conversation, and office work, an overall redesign is required.The brightness and color of these light sources have a complex effect on the driver's actions.Currently, there is a lack of research on the effect of color color and brightness change on the driver's psychology/physiology according to the combination of various light sources in the interior space of a car. As the preferred sensibility differs according to the driver's use mode (resting, reading, office work, etc.), it is necessary to understand the effect of the color change and the degree of harmony of the indoor light source on the driver's psychological/physiological factors
