Congress: Environment-on-Board Predictive Braking Control Functions for Autonomous Driving

Event: FISITA World Congress 14-16 September 2021 online

Name: Toshinori Kojima, Master's Student

Company: Tokyo University of Agriculture and Technology, Faculty of Engineering, Department of Mechanical Systems Engineering

Presentation Title: F2021-VDC-109 Environment-on-Board Predictive Braking Control Functions for Autonomous Driving During Sudden Changes in the Road Friction Coefficient on Sharp Curves

Please introduce yourself briefly…

I received a Bachelor of Science degree in engineering from the Tokyo University of Agriculture and Technology, Tokyo, Japan, in 2020. Currently, I am a master’s student at the graduate school of the university. My course is the Mechanical Systems Engineering. I am interested in vehicle dynamics and control in my research.

What you will talk about at this year’s FISITA World Congress?

In this congress, I will talk about an environment-on-board predictive braking control system for autonomous driving during sudden change in the road friction coefficient on sharp curves. The emphasis is to improve path-following performance and vehicle stability of automated vehicle, even under abnormal road conditions such as the vehicle enters a wet road from a dry road and moves on to a dry road. To achieve this objective, I will propose a function using an arbitrary curvature radius, road friction coefficient and lateral deviation which express the vehicle velocity.

What benefits will participants gain from your presentation?

From my presentation, the participants will be able to gain knowledge about autonomous driving methods that can safely drive without deviating from the lane even under abnormal road conditions such as sudden changes in the road friction coefficient.

Which trends do you consider as the most important for your domain of research and your geographical region?

I consider that the individual driver adaptive control is the most important trend for my domain of research and my region. Vehicle stability technologies such as the Anti-lock Brake System and Electronic Stability Control have already been put to practical use and have contributed greatly to the reduction of traffic accidents. However, vehicle dynamics control is still limited to what can be achieved by only vehicles. The driving characteristics of each driver are different, and if individual driver adaptive control can be realized, it will lead to further reduction of traffic accidents. In Japan, the population is aging rapidly, and the number of elderly drivers is increasing. Since the recognitive and judgmental abilities of elderly drivers are impaired, such individual driver adaptive control is considered to be very effective.

the issue is how to provide support to drivers without giving them a sense of discomfort

What challenges do these trends present?

In the research of individual driver adaptive control, it is considered that the issue is how to provide support to drivers without giving them a sense of discomfort.

And what opportunities do these trends offer?

These trends are expected to provide drivers with more optimal driving support, reduce traffic accidents, and improve driving comfort.

About the FISITA World Congress

Since 1947, the FISITA World Congress has been the leading international meeting place for industry experts, engineers and executives to exchange ideas and discuss the trends that drive the automotive industry forward. The theme for the 38th FISITA World Congress is 'From automobile to mobility. New roles. New challenges' and it will take place 14-16 September 2021, with the opportunity for the global audience to join virtually available for the first time. Registration is now open, with the Early Bird and special registration rates available until 31 August 2021.

Content from the 2020 FISITA Web Congress is available within the FISITA Technical Library, while material from previous Congress events back to 1998 is available in the FISITA Store. By the time of this year’s Congress, all the content will be available within the FISITA Technical Library, with free access provided to FISITA members.
