“Verify-on-Demand” - A Practical and Scalable Approach for Broadcast Authentication in Vehicle-to-Vehicle Communication

2011-04-12
2011-01-0584
In general for Vehicle-to-Vehicle (V2V) communication, message authentication is performed on every received wireless message by conducting verification for a valid signature, and only messages that have been successfully verified are processed further. In V2V safety communication, there are a large number of vehicles and each vehicle transmits safety messages frequently; therefore the number of received messages per second would be large. Thus authentication of each and every received message, for example based on the IEEE 1609.2 standard, is computationally very expensive and can only be carried out with expensive dedicated cryptographic hardware. An interesting observation is that most of these routine safety messages do not result in driver warnings or control actions since we expect that the safety system would be designed to provide warnings or control actions only when the threat of collision is high.

“Space-BEE: Space Biomedical Exercise Environment” A Personal Centrifuge within an Inflatable Structure

2005-07-11
2005-01-3049
This paper presents a conceptual design of a short-radius centrifuge for orbital application, contained in an inflatable structure. The objectives of this design are: to support the physical effectiveness of the crew by offering an exercise facility; to provide a test bed for biomedical experiments on human centrifugation in orbit; and to offer recreational benefits during long periods of confinement. The use of a pneumatic structure that can expand in orbit allows maximizing the radius of the centrifuge within mass and launch constraints. The proposed project is composed of elements with standard interfaces; its environmental design is based on human factor considerations from biomedical literature, and it respects current ergonomics and NASA standards.

Posture and gait controls underlie the fundamental physical and cognitive human factors necessary for astronauts’ safety and performance in Space. This central subsystem is adversely affected when exposed to an extreme or hostile environment. A specific stimulation, using dermal optical sensitivity, can be provided to the central nervous system to counteract peripheral stimulations due to microgravity as well as other negative stressors. We believe using dermal optical sensitivity-based stimulation can be key in the performance enhancement necessary to ensure human based space mission viability and success.

“Personal Integrity” and Man-Machine Integration

1982-02-01
821348
A sense of “personal integrity” blocks pilot use of new information about how he thinks. Research on human performance under stress done over the past fifty years indicates increased rigidity and regression to earlier learned behavior in high stress, and in low Stress a shift in attention to any domestic situation or on the job controversy which is of higher stress than that of the job at hand, all without the pilot's knowledge. Informal surveys of commercial pilot training and commercial pilot attitudes towards these studies indicate that the study findings directly confront learned cultural responses. Pilot and trainer reactions prevent the information from being adequately investigated or formally taught. The findings are not written into training manuals and pilots who are informally given the information do not have adequate access to the knowledge when it is needed.

“Pedestrian in the Loop”: An Approach Using Augmented Reality

2018-04-03
2018-01-1053
A large number of testing procedures have been developed to ensure vehicle safety in common and extreme driving situations. However, these conventional testing procedures are insufficient for testing autonomous vehicles. They have to handle unexpected scenarios with the same or less risk a human driver would take. Currently, safety related systems are not adequately tested, e.g. in collision avoidance scenarios with pedestrians. Examples are the change of pedestrian behaviour caused by interaction, environmental influences and personal aspects, which cannot be tested in real environments. It is proposed to use augmented reality techniques. This method can be seen as a new (Augmented) Pedestrian in the Loop testing procedure.

“Multi Vector” Field of View Design Tool

2004-03-08
2004-01-0380
A multi vector design tool to accurately predict instrument panel obscuration was developed to insure that critical legal displays in vehicles are not obscured. The concept provides for a computer generated light source shaped to replicate the human eyes. The light source is then projected onto a 3D math based arrangement and the resultant shadows are visible on the instrument panel surface and its displays. Design studios require criteria for the placement of the instrument cluster gages and displays, various controls, switches, and steering column stalks before an interior theme can be completed. Therefore, instrument panel obscuration and visibility must be determined early in the design process. The obscured areas are a function of the instrument panel surface, steering wheel rim, hub, spokes, and the location of the driver's eyes. This light source method allows engineers and designers the ability to quickly determine obscured areas.

“Fitting Data”: A Case Study on Effective Driver Distraction State Classification

2019-04-02
2019-01-0875
The goal of this project was to investigate how to make driver distraction state classification more efficient by applying selected machine learning techniques to existing datasets. The data set used in this project included both overt driver behavior measures (e.g., lane keeping and headway measures) and indices of internal cognitive processes (e.g., driver situation awareness responses) collected under four distraction conditions, including no-distraction, visual-manual distraction only, cognitive distraction only, and dual distraction conditions. The baseline classification method that we employed was a support vector machine (SVM) to first identify driver states of visual-manual distraction and then to identify any cognitive-related distraction among the visual-manual distraction cases and other non-visual manual distraction cases.

2024-04-09
2024-01-2012
Driver state monitoring is a crucial technology for enhancing road safety and preventing human error-caused accidents in the era of autonomous vehicles. This paper presents CogniSafe, a comprehensive driver monitoring system that uses deep learning and computer vision methods to detect various types of driver distractions and fatigue. CogniSafe consists of four modules: Driver anomaly detection and classification: A novel two-phase network that proposes and recognizes driver anomalies, such as texting, drinking, and adjusting radios, using multimodal and multiview input. Gaze estimation: A video-based neural network that jointly learns head pose and gaze dynamics, achieving robust and efficient gaze estimation across different head poses. Eye state analysis: A multi-tasking CNN that encodes features from both eye and mouth regions, predicting the percentage of eye closure (PERCLOS) and the frequency of mouth opening (FOM).

‘Motoring Which?’ — Eighteen Years of Human Factors in Comparative Car Testing — An Historical Review

1980-02-01
800332
In 1961 the Consumers’ Association in Britain set up a car test unit, and in 1962 the first car test reports were published. These later became the ‘Motoring Which?’ quarterly supplement to ‘Which?’ magazine. The methods and general sequence of the CA car testing procedure are first outlined. The Human Factors contribution to this testing programme is then described. The contribution broadly takes two forms. First, human factors reference data and guidance are provided to assist with the planning and interpretation of the objective measurement programme run by the test unit. Second, an extensive Human Factors Questionnaire (HFQ) programme is organised, and the results are reported, quarterly for every group of test cars. The initial planning of the Human Factors contribution is described; then the essential features of the HFQ programme, and its successive stages of development over the years to the current form with computerised analysis and output are reviewed.

iDrive – The New Interaction Concept for Automotive Cockpits

2002-10-21
2002-21-0042
The very first objective of each HMI system is to arrange its handling as intuitive and easy as possible so that the driver can concentrate on the driving, which means driving in a safe manner as well as real fun to drive. Since the arrival of microelectronics, the number of functions in the vehicle which go beyond the straightforward business of driving have been ever increasing. This enormous range of functionality and information should continue to be usable easily and intuitively by the most varied types of driver without diverting the driver's attention from the traffic and putting the safety of the driver and passengers at risk. With the new operation concept iDrive BMW has set a big milestone.

electric Vertical Take Off and Landing (eVTOL) Emergency Lighting

2023-09-14
WIP
ARP8620
The purpose of this ARP is to provide criteria that will lead to and support existing regulatory standards of systems for UAM/AMM/eVTOL aircraft such that the emergency systems will facilitate egress under emergency conditions. Consideration is given to existing requirements of the FAA and to the recommendations of aircraft operators and those involved in the manufacture or use of the emergency lighting system. Occupant safety is the primary objective, with appropriate provisions for crew (pilot) system control taken into consideration. Consideration is also given to autonomous aircraft in which passengers are required to egress without the aid or direction of crew. The criteria established herein are intended to produce an emergency lighting system that will comply with the Federal and International Regulations. However, these recommendations are but one means of meeting the objective.

eNOTIFY: Definition of a Methodology and Tools for Automatic Identification and Notification of Road Accidents

2012-04-16
2012-01-1178
Worldwide, 1.2 million people die in road crashes yearly; 43,000 in Europe alone. This implies a cost to European society of approximately 160 billion euros, and takes up 10% of all healthcare resources. To reduce these rates, safety technologies have been developed which help to minimize the severity of injuries to vehicle occupants. However, studies have shown that most deaths due to road accidents occur in the time between the accident and the arrival of medical care. Therefore, a fast and efficient rescue operation would significantly increase the injured person's probability of survival. The aim of this project was to define the On-Board Unit (OBU) hardware and software installed in all modern vehicles which could request medical and technical support after a road accident. This device, based on the information from the vehicle sensors, automatically decides whether the car has suffered a road accident or not, the severity of the accident and the kind of accident (impact area).

891529
For human beings who have been reared on the earth with its 1 G gravitational field, the condition of weightlessness is a world with which we are unfamiliar. Even if the layout and equipment configuration of a spacecraft designed to compensate for operation under Zero-G conditions, there are some things which are not effective under actual weightless conditions. In the design of a manned spacecraft, it is necessary to accumulate design data on human performance in a weightless condition, then to undertake design evaluations and verification under weightless conditions. In this paper, testing for the purpose of evaluating the effectiveness of Zero-G simulation using neutral buoyancy, conducted first of all in Japan, and recommendations on the equipment and Facilities required to conduct such simulations, are described.

Zero Hand Coding Approach for Controller Development

2002-03-04
2002-01-0142
As the demand for more complex system development and the ever-increasing requirement for improvement in software productivity, the need for graphical programming or Zero-Hand Coding for automatic generation of controller software becomes highly desirable. The graphical programming must not be limited to the algorithm development which consists of the application modules but must be extended to the microcontroller platform, which include the middleware (i.e. operating system, I/O device drivers) and hardware. Automatic code generation is very important for programming the complex microcontroller internal parameters and registers. The combined software tool chain is to generate the final target specific executable code. This approach is very beneficial for system development, reduction of the development cycle and bridges the gap between control and software engineers reducing time, effort and cost of the production software.

XMM - RGS Cryogenic Detector Housing

1994-06-01

The Reflection Grating Spectrometer experiment (RGS) on the ESA corner stone X-Ray Multi-Mirror Mission (XMM) uses charge coupled devices (CCD) as detectors. Thermal requirements are the main driver for the layout of the detector housing. Parasitic heat inputs stem primarily from radiative coupling and from conduction over the structural support. Improvements in the design of the electro optical model (EOM) over the bread board model (BBM) resulted in a system that guarantees a CCD temperature of -130 °C at the end of the mission while not precluding the possibility to heat the detectors as high as +130°C which might be useful for annealing the CCDs.

Worldwide Truck Electronic Systems -- Trends for the 90s

1986-11-01
861970
It is the goal of this paper, to discuss the impact of electronics on modern day commercial vehicles an buses. Seen from the position of advanced engineering of an European commercial vehicle manufacturer, the emphasis will be placed on the mechanical-electronical system itself, rather than the electronics themselves. User friendly, logic protected systems will minimize operator unfamiliarity and misapplication and will offer not only component control, but shortly the integration of all of these subsystems in the total vehicle control. Total vehicle control will be the ultimate result, when the driver, the truck and the environment are brought together. Such vehicles will be more responsive, safer and easier to drive than today's commercial vehicles and buses and offer a cost effective utilization of these new technologies to the customer.

Workspace Analysis and Visualization for Santos'™ Upper Extremity

2005-06-14
2005-01-2739
Workspace is an important function for human factors analysis and is widely applied in product design, manufacturing, and ergonomics evaluations. This paper presents the workspace analysis and visualization for Santos™ upper extremity, a new virtual human with over 100 DOFs that is highly realistic in terms of appearance, behavior, and movement. Jacobian Rank deficiency method is implemented to determine the singular surfaces. The joint limits are considered in this formulation; three types of singularities are analyzed. This closed-form formulation can be extended to numerous different scenarios such as different percentiles, age groups, or segments of body. A realtime scheme is used to build the workspace library for Santos™ that will study the boundary surfaces off-line and apply them to Santos™ in the virtual environment (Virtools®). To visualize the workspace, we develop a user interface to generate the cross section of the reach envelope with a plane.

Workload Analysis Method via Optimal Driver Model

2004-11-30
2004-01-3536
Race car design requires precise estimation of car behavior under aggressive driving conditions. Ground vehicles are highly complicated man-machine systems, in which driver operation plays a great role. Thus, analysis based on a driver model is advantageous. In this research, an H∞ optimal driver model is formulated, and the cost index of the operation workload, which is derived from the lead operation of the driver, is developed. In addition, sensitivity to disturbances, such as bumps on the road, is evaluated using control theory. The proposed method can estimate workload and the effects of disturbances on man-machine systems. This is especially valuable for First Order Analysis. Several parametric studies have contributed to the development of guidelines for high-performance car design to guarantee a good workload level, high tracking performance, and low disturbance sensitivity.
