Published 2016-04-05 by SAE International in United States
Controller area network (CAN) technology is widely adopted in vehicles, but attention has been drawn recently to its lack of security mechanisms. Numerous countermeasures have been proposed, but none can be regarded as a generic solution, in part because all the proposed countermeasures require extensive modifications to existing in-vehicle systems.To arrive at a solution to this problem, we propose a new method of protecting CAN without the need to modify existing systems. In this paper, we explain the principle of our proposed method and the architecture of the electronic control unit (ECU) that implements it. We report the result of our experiments and show its efficacy against typical security threats faced by CAN.

This paper investigates influence on driver's useful visual field when using car navigation while driving. In the experiment using a driving simulator, two types of visual target were presented in driver's peripheral visual field, and the subjects were instructed to drive while detecting the presented target and judging the shape of the target as a visual task. The performance of visual task and driver behavior was analyzed, and the influence on driver's useful visual field was discussed based on the types of car navigation task, road alignment and traffic condition.

Published 2010-09-29 by Society of Automotive Engineers of Japan in Japan
This paper investigates effects of environmental factors and driver distraction on eye-fixation-related potentials (EFRP) while driving. Various experimental conditions such as brightness and traffic condition were set up as the environmental factors in a motion-based driving simulator, and moreover several cognitive tasks were given to the participants while driving. Based on the obtained results, the relationship between EFRP, driver distraction and environmental factors was discussed.

Published 2009-05-20 by Society of Automotive Engineers of Japan in Japan
The academic-industrial alliance project of the ITS Center, Institute of Industrial Science, and The University of Tokyo has approached improvement of realistic sensation on 'universal Driving Simulator for Human, Vehicle, and Traffic Research.' Some functions such as the turntable mechanism were installed before. Moreover, four functions for upgrading realistic sensation were added to this simulator as follows: new visual system with the target projector to improving visibility, change of turning center with moving a cabin to improve driving feeling, improvement of sound system, and implementation of a car navigation system. In this paper, these are described.

Sequences of drivers' gazing directions were experimentally obtained and analyzed. Seventeen subjects parked a passenger vehicle at an experimental parking space and gaze directions were measured with an eye-mark recorder. The analysis showed that the gazing target moved from the entrance of the parking space to obstacles nearly to contact to the vehicle. Finally position of the vehicle was adjusted viewing the end of the space.
