Study of the Human-vehicle System by a Driving Simulator with Stereoscopic Vision of Five Large Screens (Second Report)

Haraguchi Tetsunori, Gemba Makoto, Aoki Hirofumi, Tanaka Takahiro

Transactions of Society of Automotive Engineers of Japan Vol. 47 ( 3 ) page： 789 - 794 2016

Language：Japanese Publishing type：Research paper (scientific journal) Publisher：Society of Automotive Engineers of Japan

We develop a driving simulator (DS) to be used for the human-vehicle system research. It can reproduce the driving environment by immersive stereoscopic display, which has five high brightness and high definition screens. The purpose of this work using this DS is to study the fuel consumption on follow-driving as an example of real world usage. In this report, we confirm 35% - 71% increased fuel consumption of the following vehicles to the vehicle ahead. Then we compare the driver’s operations on the point of fuel consumption. And finally we study the feasibility modification of vehicle response in order to reduce fuel consumption on follow-driving.

In recent year, the number of traffic accidents caused by elderly drivers has increased. The effect of changes associated with aging in physical functions and cognitive functions is pointed out as one of the reasons. However, the car is one of important transportation for elderly. Therefore, the assistance measure to realize the safety driving for elderly drivers is needed. To overcome the problem, we are developing the agent that supports elderly drivers. The agent provides the advisement to elderly driver during driving a car and also encourages the driver to improve their driving behavior by showing their past driving records. In this paper, we described the analysis of human instructor's teaching model for considering the supporting method by the agent. From the analysis, we categorized the instructions into several groups and obtained findings about the impression of trainee caused by the instructions.

Stimulus-response behavior among senior drivers using the driving aptitude test

Language：English Publishing type：Research paper (scientific journal) Publisher：The Japanese Society for Cognitive Psychology

To discuss the development of driving-assistance systems and enhancement of driving ability, we investigated stimulus-response behavior among elderly people by using the driving aptitude test. Participants were 100 drivers and were assigned to 3 groups based on age: 50s, 60s, and over 70. All participants provided informed consent and performed several cognitive tests and the driving aptitude test including 7 kinds of tests similar to those in the Lecture for Elderly Drivers in Japan. Analyses of response times and accuracy obtained from 4 of the 7 tests showed that participants in the 60s and over-70 groups delayed their responses when they were required to discriminate among various signals and respond using the foot pedal; and showed decreased performance under the blue-signal condition. The results helped determine elderly drivers' stimulus-response behavior from the driving aptitude test data and indicated a factor-induced performance decrease during driving.

A study on the method for predicting the driver's car-following tendency

Aoki H., Ozaki O.

IFAC Proceedings Volumes (IFAC-PapersOnline) Vol. 7 ( PART 1 ) page： 319 - 321 2013

Language：Japanese Publishing type：Research paper (scientific journal) Publisher：IFAC Proceedings Volumes (IFAC-PapersOnline)

This study aimed to develop a simple method that can predict the car-following tendency of the driver. Based on the analysis of the naturalistic driving data, some parameters such as the throttlepedal released timing and the average deceleration by braking were found to be correlated with the braking timing. Therefore, the car-following tendency was predicted by a model with those parameters. The model was evaluated on the public road and it was shown that the proposed method can predict the car-following tendency well within a short distance.

Development of a Car-Following Tendency Prediction Method and Its Application to a Forward Collision Warning System

It is important to understand the driver's car-following tendency to enhance the effectiveness as well as the acceptance of advanced driving support systems. If a system can estimate the driver's usual car-following tendency, it can provide avoidance support matched to his/her sense of normal safety driving when the vehicle is approaching a preceding one. Since the car-following tendency varies not only between drivers but also within a driver by the feeling and/or the driving environment, real-time estimation is essential. This study introduces a method that can easily predict the car-following tendency. The method uses such parameters as the throttle-pedal released timing and the braking timing that were found to be correlated from the naturalistic driving data analysis. It was found that the method can predict the car-following tendency within a short distance. We applied the method to a forward collision warning system and confirmed the potential benefit of the system.
