In-Vehicle Infotainment has evolved greatly over years from a simple tuner based radio with a small LED display to a complex system with highly intelligent interactive HMI which can mirror the smart phone. The full-fledged entertainment features like watching videos are restricted to only rear passengers. In drive mode, drivers are limited with access to only audio to avoid driver distraction. Rear passengers and drivers are classified into different audio zones. Each of the rear passengers are equipped with headsets so that audio merging with driver zone can be avoided. This leads to passenger discomfort, as many passengers would not prefer to hook up with headset all the time. Now the automotive world is envisioned to reach fully autonomous mode where there is no driver and every passenger is interested to listen to music/video of diverse interest. The audio zones in autonomous car need not be zonified or linear. Circular audio zone can also be a good choice for autonomous cars. There are situations in autonomous cars where passenger is asleep in vehicle and hence…

Germany's Kempten University Adrive Living Lab will feature latest aVDS driving simulator to research ADAS stress levels.

Researchers at Germany's Kempten University of Applied Sciences plan to embark this year on autonomous vehicle (AV) and advanced driver-assist system (ADAS) programs that will include investigation of the safest ways to achieve handover of a vehicle when control is returned to a human driver. To do so, it is installing an AB Dynamics advanced Vehicle Driving Simulator (aVDS) that will help measure driver stress levels if the vehicle is not capable of performing a particular maneuver. The aVDS has been designed to provide high level R&D capabilities specifically for autonomous systems.

JLR researches use of steering wheel heating and cooling to reduce driver workload

Jaguar Land Rover (JLR) recently revealed novel research into a driver-safety aid: a sensory steering wheel rim that heats or cools on each side to warn of upcoming GPS-directed maneuvers-plus serves as an extra information source in low-visibility situations.

Developing a Custom Data Acquisition Software Package for a Self-contained Acoustic Test Facility

Kolano and Saha Engineers, Inc.-Richard Kolano, Sagar Patil, Pranab Saha
Published 2019-06-05 by SAE International in United States
This paper provides an overview of a custom software developed to obtain measurement data in a self-contained acoustic test facility system used for conducting random incidence sound absorption tests and sound transmission loss tests on small samples in accordance with SAE J2883 and J1400 standards, respectively. Special features have been incorporated in the software for the user to identify anomalies due to extraneous noise intrusion and thereby to obtain good data. The paper discusses the thoughts behind developing user-friendly algorithms and graphical user interfaces (GUI) for the sound generation, control, data acquisition, signal processing, and identifying anomalies.

Student Concept Vehicle: Development and Usability of an Innovative Holographic User Interface Concept and a Novel Parking Assistance System Concept

Published 2019-04-02 by SAE International in United States
The Deep Orange program is a concept vehicle development program focused on providing hands-on experience in design, engineering, prototyping and production planning as part of students’ two-year MS graduate education. Throughout this project, the team was challenged to create innovative concepts during the ideation phase as part of building the running vehicle. This paper describes the usability studies performed on two of the vehicle concepts that require driver interaction.One concept is a human machine interface (HMI) that uses a holographic companion that can act as a concierge for all functions of the vehicle. After creating a prototype using existing technologies and developing a user interface controlled by hand gestures, a usability study was completed with older adults. The results suggest the input method was not intuitive. Participants demonstrated better performance with tasks using discrete hand motions in comparison to those that required continuous motions. The data were helpful to understand the challenges of untrained users interacting with a new HMI system.The second concept is a parking assist system designed to help other drivers. A usability…

Streamlined HMIs do more with less

The phrase “less is more” has been a major part of human-machine interface (HMI) designs for several years as developers traded multiple knobs and buttons for cleaner input techniques. However, the push to simplify the control's look and feel is offset by the need to let drivers and operators manage more things, often with redundant input techniques.

A Multi-Domain Component Based Modeling Toolset for Dynamic Integrated Power and Thermal System Modeling

Published 2019-03-19 by SAE International in United States
Design of modern aircraft relies heavily on modeling and simulation for reducing cost and improving performance. However, the complexity of aircraft architectures requires accurate modeling of dynamic components across many subsystems. Integrated power and thermal modeling necessitates dynamic simulations of liquid, air, and two-phase fluids within vapor cycle system components, air cycle machine and propulsion components, hydraulic components, and more while heat generation of many on-board electrical components must also be precisely calculated as well. Integration of these highly complex subsystems may result in simulations which are too computationally expensive for quickly modeling extensive variations of aircraft architecture, or will require simulations with reduced accuracy in order to provide computationally inexpensive models. As such, a need for software toolsets with the ability to model complex aircraft architectures with accurate calculations while maintaining high computational speeds is apparent. This paper details the development of the ATTMOSphere toolset which enables modeling of electrical, mechanical, thermal, fluid flow and heat transfer across a range of components applicable to integrated power and thermal systems. Graphical user interfaces provide user-friendly…
