A Study of Haptic Simulator for Virtual Door Open & Close Feeling Test

Jaehoon Chung (Hyundai Motor)･Kiwook Kyung･Jisung Kim (KAIST)

Haptic simulators enable the provision of kinesthetic feedback in a virtual environment. This study used a haptic simulator to produce the force and movement of a car door during opening and closing. Since a car door has many components and various factors influence each other, the relationship between each factor must be accurately modeled to produce the tactile feeling of a car door with a simulator. Therefore, the door opening and closing torque was classified into passive and active torque, and each torque was implemented by a brake and a motor. In addition, door inertia has a significant impact on the door opening and closing feeling and movement, this factor was also implemented to develop hybrid haptic simulator. This shows that it is possible to experience a car door opening and closing feeling in a virtual environment without a physical door.

Customized interior lamp control
by detecting and determining the condition of passengers

SUNG HO PARK (Hyundai Motor)

The main function of the camera in the vehicle is to monitor the carelessness of the driver, such as drowsiness, and it is expected to be mandatory for new cars in the future. The function using the camera is expected to increase to monitor the presence of passengers and health conditions. In this study, the driver's condition is judged based on facial expressions and heart rate by using the camera in the vehicle and the mood lighting, thereby ensuring a safe and comfortable driving environment. It is intended to study a method of controlling a mood lamp that can be constructed.

New Euro NCAP Protocol for General Vehicle Controls: Redefining Safety Standards for Driver Interaction Through Vehicle Design

James D. Jackson (Applus IDIADA)

Driver distraction is recognised by Euro NCAP as a key contributing factor in risks associated with road traffic accidents. As part of the Vision 2030 strategy, a new General Vehicle Controls protocol will aim to encourage vehicle manufacturers to implement good practices which avoid distractions by design. Poor interaction design can contribute to drivers looking away from the road for extended periods, whether performing driving-related tasks or whilst using other vehicle functions. Euro NCAP will reward control design that minimises drivers looking away from the road.
This presentation will explore the following topics relating to the new protocol:
- Premise and background of HMI assessment for vehicle safety
- Development of the protocol, its structure and scope, and definition of the test procedure
- Insights from pilot implementations and guidance to industry from IDIADA experience.

Assessing Driver Engagement in a Driving Simulator

The adoption of ADAS at Levels 2 and 3, combined with advanced occupant monitoring systems, has improved vehicle safety and comfort. However, concerns about driver attention and engagement persist, as users may not fully understand system limitations or their responsibility when systems are active. To address this, regulations emphasize "driver engagement" through monitoring, cooperation, and clear communication. IDIADA's Human Factors team developed a methodology tested in proving grounds and now implemented in a dynamic driving simulator. This study, conducted in China with 40 participants, collected subjective, objective, and physiological data, validating the approach and emphasizing the balance between technology and human control for safe systems.

A Study on Optimal Energy use for operating moving parts in vehicle

Seokjin Park･Kyungsup Chun･Jaeyoon Ryoo･Minhyung Byun･Sanghyun Lee (Hyundai Motor)

Operating sensibility refers to actual usability of consumers. There are techniques to evaluate sensibility, but it is based on force-oriented and inadequate to represent various consumers. In addition, property units of each part are different. It means that current techniques lack correlation with consumer sensibility. The purpose of this study is to propose energy evaluation method. First, we present methods that reflect needs of various consumers. Second, based on consumer energy, we determine improvement needs of various parts and suggest goals. Ultimately, all parts can be evaluated based on consumer sensibilities, and performance can be strengthened to secure product value.
