The intent of this SAE Aerospace Information Report (AIR) is to describe the effects of the environmental changes on human physiology and the protection required to avoid negative consequences resulting from altitude exposure. A brief presentation of basic terms and considerations required to discuss the topic of human physiology at altitude are followed by an overview of the cardiovascular and respiratory systems. Issues specifically related to human exposure to altitude are then discussed. Hypoxia, hyperventilation, barotrauma, and decompression sickness (DCS) are each addressed: hypoxia is defined as an insufficient supply of oxygen to the tissues, hyperventilation is an excessive rate of ventilation with ultimate consequences on acido-basic equilibrium, barotrauma is injury caused by pressure: most commonly referencing injury to the walls of the Eustachian tube and the ear drum due to the difference between atmospheric and intratympanic pressures, and DCS is related to an excess of nitrogen in the body tissues.

The Road/Lane Departure Warning System is a crash-avoidance technology which warns drivers if they are drifting (or have drifted) out of their lane or from the road. This warning system is designed to help prevent the possibility of a run-off-road crash. This system will not take control of the vehicle; it will only let the driver know that he/she needs to steer back into the lane. This warning system is not designed as a lane-change monitor, or a merging system which warns of other vehicles. This informational report applies to OEM and after-market Road/Lane Departure warning systems for light-duty vehicles on relatively straight roads with a radius of curvature of 500m or more, and under good weather conditions. Future revisions should consider the implications of newer variations on the user experience.

Recently, there have been many reports about developing control systems that actuate engines and brakes based on friction circle. We are researching the control system for motorcycles, which adds the return torque of throttle grip based on it for informing the limit of tire grip on the driving wheel. This throttle grip is a haptic display, offers haptic signals by controlling the motor connected to the throttle grip as a HMI. From the results of riding tests, the system was found helpful for riders to control the throttle grip as well as feeling easy about knowing the limit of tire grip. But it is known that the friction circle of a driving wheel depends on the normal force which changes by the gradient of road, acceleration and so on. The compensated control for changing the normal force by gradient was made to improve the throttle grip control system. The results of riding tests with the compensated system, we found that this system is important for the controls based on friction circle and it makes the haptic signals come close to the timing that riders want.

Even though a number of developed countries enjoy a high level of vehicle safety, more than 1.2 million fatalities still occur each year on roadways worldwide. There remains a need to continue improving vehicle and road safety. New technologies in sensors and electronic control units, and the growing knowledge of car-to-car and car-to-infrastructure technologies have led to a fusion of the previously separated areas of accident avoidance (popularly known as active safety) and mitigation of injuries (popularly known as passive safety) into the newer concept of integrated vehicle safety. This new approach represents a further step toward lowering accident rates. This book, written by two of the foremost automotive engineering safety experts, takes a unique and comprehensive approach to describing all areas of vehicle safety: accident avoidance, pre-crash, mitigation of injuries, and post-crash technologies, providing a solutions-based perspective of integrated vehicle safety. Also covered are accident investigation and worldwide legislation as they apply to integrated vehicle safety.

From simple collisions to major tragedies, car accidents happen every day. Automobile industry has been investing a lot in security systems (e.g., airbags, ABS brakes, vehicle proximity warning systems). However, drivers are still the ones who have to act in order to avoid collisions, by using the brakes or maneuvering the car. The purpose of this project is to develop an anti-collision logic that can be used on automobile vehicles to avoid collisions with both static and moving objects by interfering on the vehicle behavior. The control system is based on a fuzzy modeled controller using the MATLAB and Simulink tools from Math Works. The prototype chosen to test the logic was the Robotino, a mobile robot system made by Festo Didactic, and used for educational, training and research purposes. Robotino is able to integrate to Simulink tool natively, and provides out-of-the-box sensors and actuators, so the developers are able to focus the efforts on the software itself. Integrated simulations were done using FESTO Robotino Simulator to validate whether the proposed system meets the objectives or not.

By using telecommunications, Intelligent Transport Systems (ITS) improve traffic safety and efficiency, facilitating an integral transport of people and goods. Even with the benefits obtained through ITS Systems nowadays, significant innovations will take place in the following years such as the ubiquitous and integral use of computer vision, or the development and future implementation of Cooperative ITS (C-ITS) that will allow a direct communication between vehicles (Vehicle-to-Vehicle, V2V) and with the roadside elements (Vehicle-to-Infrastructure, V2I) by means of mobile and wireless communication. In this context, the INTELVIA project was implemented, with the clear objective of developing ITS technologies and Intelligent Human-Machine Interfaces (HMI) to obtain the advantages of using information and communication technologies in the field of road transport and traffic management.

The interaction between human operator and equipment in general can be made easier or harder depending on the effectiveness of the interface used for this interaction. The present work focuses on this interface - the so called ‘Human-Machine-Interface’ (HMI) for a specific set of equipments: the vehicles (passenger cars and commercial road vehicles). Vehicles need to be driven by professional and amateur drivers. The HMI of the vehicle needs, thus, to be adequate to a wide variety of drivers, allowing for a safe and enjoyable ride. The design of such an HMI must then consider several aspects that are human centered (physiological, psychological, sociological…) and machine centered (technological). The present work discusses briefly these aspects, their dynamics. The analysis of both vehicles and some other technology products are analyzed, and the trend of vehicle HMI's is drawn on a broad sense. It is shown that electronics play a key role in current HMI; and that this role is becoming more and more important.

The purpose of this document is to establish air conditioning design guidelines that will apply to most systems rather than the specific design of any particular system. Operating conditions and characteristics of the equipment will determine the design of any successful system, and since these characteristics and conditions vary greatly from one application to another, the designer must determine the goals expected to be reached under the conditions encountered. To determine the capacity of such items as blowers, condenser fans, condenser coils, evaporator coils, filters, compressors, etc., will require the adherence to several guidelines, some of which are outlined in this document.

A two-stage preview strategy is proposed to characterize steering control properties of commercial vehicle drivers. The strategy includes a near and a far preview points to describe the driver control of lateral path deviation and vehicle orientation. A human driver model comprising path error compensation and dynamic motions of the limb is subsequently formulated and integrated to a yaw-plane model of an articulated vehicle. The coupled driver-vehicle model is analyzed under an evasive steering maneuver to identify limiting values of the driver control parameters through minimization of a generalized performance index comprising driver's steering effort, path deviations and selected vehicle states. The performance index is further analyzed to identify relative contributions of different sensory feedbacks, which may provide important guidance for designs of driver-assist systems (DAS). The results show that the proposed model structure could serve as an effective tool to identify human control limits and to determine the most effective motion feedback cues.

Shift quality of a manual transmission is a critical characteristic that requires utmost care while structuring the transmission. Shift quality is affected by many factors viz. synchronizer design, shifter design, gear design, transmission oil selection etc. This paper presents a correlation between stiffness of the shift fork in manual transmission with the gear shift quality using a gear shift quality assessment setup. Stiffness of shifter fork is optimized using contact pattern analysis and stiffness analysis on MSC Nastran. All the subsystem (i.e. synchronizer and the shift system component) are constrained to optimize the shift fork stiffness. A-5-speed manual transmission is used as an example to illustrate the same. A direct correlation of gear shift fork stiffness with the shift force experienced by the driver is established. The shift system was modeled in the UG NX 6.0 software to collate the synchronization force, shift system gap etc with the constraint on the shift fork. The shift fork is constrained by the synchronizer sleeve and the fork mounting on the gear shift rail.
