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.

Safety, Ergonomics and comfort are inseparable concepts and of greater relevance to the full exercise of professional drivers, being the seat, one of the most important components to be considered, when designing their workplace. This work presents initiatives taken by Mercedes-Benz do Brasil Ltda. (MBBras) in partnership with GRAMMER do Brasil Ltda. (Grammer) and Oficio Ergonomia e Design Ltda. concerning the improvement of a SAE Class 8 Heavy-truck Driver Seat. Proposals involved seat design improvement at driver reach and posture, design and constructive characteristics (seat-bottom foam and frame) Upholstery, seat-controls ergonomics and the vibration response, due to the introduction of independent shock-absorbers. A user centered approach was employed to promote the necessary interaction between the major synergic areas: ergonomics, engineering, manufacturing and design, in order to guarantee that the greatest number of demands coming from future customers - here represented by a selected group of drivers - was brought to reality.

The purpose of the recommended practice is to define a list of operator precautions that should be stressed in operator training and in the preparation of operator manuals. These general operator precautions apply to off-road work machines as defined in SAE J1116 JUN85, Categories one, two, four and five and agricultural tractors in Category three. These should not be considered as all inclusive for all specific uses and unique features of each particular machine. Other more specific operator precautions not mentioned herein should be covered by users of this recommended practice for each particular machine application.

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.

This Aerospace Recommended Practice provides design and installation criteria intended to enhance overall safety by mitigating exposure of cabin crew and passengers to risks from: a. Routine use of galley systems. b. Galley components or equipment becoming dislodged under routine or abnormal operating conditions and under survivable crash or ditching conditions. c. Malfunctions of, or defects in, a galley system or associated galley equipment. NOTE: It is not the purpose of this Aerospace Recommended Practice to specify the specific designs or design methods to be followed in the accomplishment of stated objectives.

The aging of the world population, and call for greater equality in access to public environments has led to an increase in design for persons with reduced mobility (PRM). There are numerous physical and operational constraints and parameters to overcome when designing a successful and marketable PRM environment. Each program evaluates what is to be considered reasonable based on these guidelines (cost, weight, manufacturability, airframe curvature, footprint required, regulations, and usability). However, there are other less tangible parameters to address. For example, what level of dignity or level of privacy does the PRM environment allow? Does the design require additional assistance to access, or can those who are able make independent use of the environment? Most aircraft manufacturers and design entities have recognized the need to improve accessibility aboard single aisle commercial aircraft (Airbus 320 family, Boeing 737, Embraer 190, Bombardier CSERIES). Current efforts are a step in the right direction, but significant effort and continued improvement is required to accommodate the mobility impaired segment of our travelling public.

The scope of this Vertical Flight document is limited to human behavioral technologies associated with design and/or implementation of Enhanced Synthetic Vision Systems (ESVS) in vertical flight aircraft. Any overlap into logic problems or hardware/software design shall be considered to be incidental to the human factors issues. Where the performance characteristics of specific technologies are relevant they will be identified, and where performance criteria are relevant to specific intended functions/use they will be identified. From a regulatory view, intended function (Full Flight Guidance or Information/Situation Awareness support) has a tremendous effect upon the design of an ESV System. However from a Human Engineering standpoint, the information on display must be discernible and comprehensible to the human operator in both cases and differences may be primarily in information content (required to support a specific task). The document is independent of candidate technologies and concentrates on human interface criteria.

Radar is expected to expand beyond its current role as a forward-looking sensor on luxury vehicles to a mainstream offering that also scans sides and possibly the rear of the vehicle. Freescale Semiconductor is hoping to cash in on this potential growth market with a specialized chipset that it says will lower pricing, simplify the design cycle, and save as much as 40% in board space.
