A study of repeatability and reproducibility of the SAE J4002 and SAE J826 H-point machines (HPMs) was conducted using 15 operators, five of each type of HPM, and four different vehicle seats. Each op....
Comfort in automobile seats is multifactorial and extremely complex problem. Many of the current sophisticated measuring tools are underexploited if they are not framed into a clear methodological app....
This study reports the objective results from a project investigating the effectiveness of several newly proposed metrics to compare fatigue performance between two distinct truck seat cushions, speci....
Seat lumbar support is thought to be essential for seating comfort as it plays important role in the driver's fatigue during long term driving. We tried to evaluate the lumbar support performance obje....
In this report, we proposed an objective evaluation method of the seat lateral support according to the mechanisms to create the performance differences that we reported previously [1]. First, we show....
Ejection seat cushions in current U.S. Air Force aircraft are not suitable for comfort during extended missions. Specific physiological problems such as buttock, leg and back pain, numbness and tingli....
Effects of hands-free phone conversations on drivers' visual behavior and detection performance were examined using a gaze-tracking device and fixed-based driving simulator. The participants engaged i....
Recently, more and more advanced and sophisticated systems have been equipped on a vehicle for greater driving comfort and convenience. When operating these systems during the driving, however, the dr....
This paper presents a process and its results used to define and design interior items such as controls, displays, handles, etc. for a low mass vehicle (LMV) being developed at the University of Michi....
How do in-vehicle telematics devices influence mind-on-the-drive? We determined the spatio-temporal properties of the brain mechanisms during a simple visual event detection and motor response in a va....
The present paper describes two studies performed with the aim of developing a human factors evaluation technique for the total vehicle based upon users' subjective experience while interacting with a....
Typically, driver interactions with in-vehicle devices such as navigation systems have been accomplished using a visual-manual interface. As a result of recent advances in technology, voice activated ....
In this paper, we use electrocardiogram (ECG) measurements to detect a driver's mental state and to investigate the relations between the driver's heart rate and his/her behavior while driving. We use....
The authors performed an experiment on a collision avoidance system (CAS) by using a driving simulator. A driver is exposed to a variety of events designed with the support system. In each event, base....
Driving tests were conducted using an experimental vehicle equipped with an adaptive cruise control system incorporating low-speed following capability in order to evaluate drivers' trust in a driver ....
There is evidence that consumers' emotions can affect their behavior and performance when performing tasks using a system [1]. In the automotive industry, it is particularly important to focus on cons....
Several previous studies report driver response times when responding to a lead vehicle. There have also been other studies that examined and measured the ability of drivers to detect the relative vel....
Video recordings of real life traffic crashes and near crashes were analysed for driver response choice. These responses were compared to problem solving theories. In emergency situations drivers were....
The Alliance of Automotive Manufacturers (Alliance) has produced a document in which Principle 1.4 gives criteria and methods for calculating downvision angles to navigation and telematics displays in....
In this paper we propose a new multi-functional steering wheel switch for HVAC and audio systems. This new switch has five buttons on the front side of the spoke area and one button with vibration on ....
