Although many have an idea of what the term “driver distraction” means, there is no common definition within the research community. Additionally, there are many studies that have investigated the topic, but with varying and sometimes conflicting results. What should be made of these discrepancies? This four-hour web seminar will provide an overview of driver distraction (predominantly electronic devices): the problem; how to define it; the current state of research and how to critically evaluate that research to make informed decisions; and the effectiveness of state laws and fleet policies to reduce it.

When specifying an embedded system-to-be, a key consideration is how the embedded system will interact with its operating environment. Of particular concern, is the system's vulnerability to Off-Nominal Behaviors (ONB) from human interaction. ONB vulnerability can result in human operators placing the system in an undesired state through an unforeseen sequence of events. This, in turn, can have an adverse effect on the system’s quality. Reducing ONB vulnerability can be challenging because human behavior can be unpredictable and stakeholders have a natural tendency to assume the system will be used in a predictable, nominal, manner. One approach to reducing ONB vulnerability is to specify the system as "fool-proof" as possible, during the requirements phase, where access to domain experts is at its most convenient.

Mobile Earth Moving Machinery like Skid-steer loaders have a tight turning radius in limited spaces due to a short wheelbase which prevents the use of suspensions in these vehicles. The absence of a suspension system exposes the vehicle to ground vibrations of high magnitude and low frequency. Vibrations reduce operator comfort, productivity and life of components. Along with vibrations, the machine productivity is also hampered by material spillage which is caused by the tilting of the bucket due to the extension of the boom. The first part of the paper focuses on vibration damping. The chassis’ vibrations are reduced by the use of an active suspension element which is the hydraulic boom cylinder which is equivalent to a spring–damper. With this objective, a linear model for the skid steer loader is developed and a state feedback control law is implemented.

The noise generated by the flow of air past a transport truck is a key design factor for the manufacturers of these vehicles as the sound levels in the cabin are a significant component of driver comfort. This paper describes a demonstration study to measure the in-cabin aeroacoustic environment of a full-scale cab-over tractor in the NRC 9 m Wind Tunnel. Acoustic instrumentation was installed inside the tractor to record cabin noise levels and externally to acquire tunnel background noise data. Using a microphone mounted on the driver’s-side tunnel wall as a reference to remove variations in background noise levels between data points, differences in cabin noise levels were able to be detected when comparing the tractor with different configurations. The good repeatability of the data allowed for differences of as little as 0.5dB to be measured.

Many assembly processes, particularly in the manufacture of aircraft components, are still carried out by humans manually. In addition to rationalization aspects, high quality requirements, non-ergonomic activities, the lack of well-qualified workers etc. may require the use of automation technology. Through novel possibilities of human-robot-cooperation these challenges can be met through a skills-based division of labor. Tasks are assigned to humans and robots in a way that the respective strengths can be used most efficiently. This article presents, how assembly processes can get empowered for human-robot-cooperation, using a specific work description for humans and robots, an assembly priority chart and suitable robot programs, to prepare for a skills-based task assignment. In the area of formerly exclusively manual assembly, the operations for the assembly of the product must first be described in detail.

Today’s drivers have to deal with a growing amount of information coming from in-vehicle infotainment systems. The interaction between the driver and the system is critical because it might distract the driver from the primary task of driving. To make the in-car interactions more convenient and intuitive, gestures and gesture recognition are terms increasingly arisen in discussions of human-computer interaction, and application trials of gesture control have appeared more and more in automotive industry. The aim of this study is to find out if gestures can reasonably be used to control in-car devices. Since there exists a big cultural difference of gesture between different countries because of its particularity, a set of gestures which support intuitive human-machine interaction in an automotive environment is searched. The results show a gesture dictionary for a variety of on-board functions, which conforms to Chinese drivers’ driving habits.

This paper aims to determine how vehicle driver steering behavior seen in the emergency lane change event. Through the emergency lane change cases extracted from the China naturalistic driving data, the driver’s steering characteristics can be obtained and analyzed. Then the driving steering behaviors divides into avoidance and stabilization steering phases, and the different steering characteristics were found. It’s shown that during the avoidance phase, the steering generally follow the bell-shaped profiles of steering angle rate, and a linear relationship was found between the maximum steering wheel rate and steering wheel angle, which indicates a constant movement time for the avoidance steering. However, during the stabilization phase, the steering angle rate can be described using two or more overlapping bell-shaped profiles, something which relates to the different steering strategies in the avoidance phase.

With the development of the society, automobiles have been widely used in various classes of the society, while some issues came out such as traffic safety, environmental pollution and energy shortages and became increasingly serious. It reported that good driving behaviors can be applied to driving assistance, active safety, fuel economy improvement and others aspects to alleviate this problem. This thesis proposed that by way of data acquisition and identification of driving behaviors based on vehicle bus, it can be identified the driver’s driving habit and accelerating intentions through these information without additional sensors. Firstly, K line and CAN line, which are known by the current mainstream vehicle bus, are selected as the research object, then we analyzing communication protocol of bus data link layer, data transport layer and application layer according to the OSI model.

With the development of automotive HMI and mobile internet, many interactive modes are available for drivers to fulfill the in-vehicle secondary tasks, e.g. dialing, volume adjustment, music playing. Considering the secondary tasks are always fulfilled simultaneously with the main task – driving itself, efficiency and safety are very important factors for the secondary tasks. Besides, drivers have high expectation for user experience of the new interactive modes. Thus, it is urgent to effectively evaluate which is the most suitable interactive mode with good efficiency, safety and good user experience for each secondary tasks, e.g. steering wheel buttons, voice control, in-air gestures, etc. This study uses a static driving simulation cockpit to provide driving environment, and sets up a high-fidelity driving cockpit based on OKTAL SacnerStudio and three-dimensional modeling technology. The secondary tasks supported by HMI platform are designed by customer demands research.

Americans are wary of driverless cars. In this episode of SAE Eye on Engineering, Editor-In-Chief Lindsay Brooke looks at a recent national survey following the death of a Tesla Model S driving using his car's "Autopilot" feature. SAE Eye on Engineering also airs Monday mornings on WJR 760 AM Detroit's Paul W. Smith Show. Access archived episodes of SAE Eye on Engineering.
