A car-following assisting system named the rear window notification display (RWND) was developed, with the aim of improving a driver's manual car-following performance. The RWND presented lead-car acceleration and time headway (THW) (i.e., intervehicle distance divided by the speed of the following car) on the rear window of a lead car, which was driven automatically. A simulator-based experiment...
Various advanced driver assistance systems (ADASs) have recently been developed, such as Adaptive Cruise Control and Precrash Safety System. However, most ADASs can operate in only some driving situations because of the difficulty of recognizing contextual information. For closer cooperation between a driver and vehicle, the vehicle should recognize a wider range of situations, similar to that recognized...
Mixed traffic denotes the coexistence of two driving styles: human and automated driving. Until now, there has been an ambiguity about the driver's safety in mixed traffic. Traffic safety studies focus on a synthesis of control laws which help drivers to avoid or mitigate collisions. Classic safety descriptors use only the time to collision, a time criterion for safety assessment. Other assess traffic...
This paper presents an investigation of a research project titled “Innovative Seating Systems” by BMW Group “Research and Technology” Team. It is based on my idea and reports about “Benefits of using Bionic Seats in Roadster cars” which is submitted and accepted by BMW Group Co-Creation Lab in March 2010. In this paper, three BMW Group revolutionary innovative seating systems, Bionic Seat, Ergo Seat...
In this paper, the problem of collision avoidance between two vehicles is considered, in which one vehicle is autonomous and the other one is human-driven. This problem arises in cooperative active safety systems at traffic intersections, mergings, and roundabouts, in which some vehicles are equipped with on-board communication and automatic control, while others are not capable of communicating and...
This paper presents a power assist robot system developed for manipulating objects in horizontal direction in cooperation with a human. Weight perception was included in robot dynamics and control. The robot was simulated and optimum maneuverability conditions for object manipulation in horizontal direction were determined. Psychophysical relationships between actual and perceived weights were determined,...
Safety is a major concern in many complex robotized systems especially when the task implies collaboration between human and robot with the workspace sharing. In this research a theoretical representation of the integrated safety monitoring system is introduced. The monitoring system is modeled as a separated unit which decision making mechanism is based on the safety expert system (SES) data analysis...
Much is still unknown about the control of posture and postural stability within the unstable environment of an earthquake. Hence, the objectives behind this study were to investigate the lower-extremity muscular response and head acceleration of human subjects in maintaining postural stability during the event of a simulated seismic activity. In order to achieve these goals, an earthquake simulator...
Anticipated developments in physical anthropomorphic models for automotive safety application, which may yield benefits in terms of improved automotive crash injury assessment, are outlined. Potential developments are briefly discussed by major body area and for the device as a whole. Issues involved in the quest for improved physical model performance are indicated, and likely limitations inherent...
