A Vehicle Stop-and-Go Control Strategy based on Human Drivers Driving Characteristics
Yi Kyongsu,Han Donghoon The Korean Society of Mechanical Engineers 2005 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.19 No.4
A vehicle cruise control strategy designed based on human drivers driving characteristics has been investigated. Human drivers driving patterns have been investigated using vehicle driving test data obtained from 125 participants. The control algorithm has been designed to incorporate the driving characteristics of the human drivers and to achieve natural vehicle behavior of the controlled vehicle that would feel comfortable to the human driver. Vehicle following characteristics of the cruise controlled vehicle have been investigated using real-world vehicle driving test data and a validated simulation package.
Motion Sensor Fault Detection and Failsafe Logic for Vehic1e Stability Control Systems (VSCs)
Yi, Kyongsu,Min, Kyongchan The Korean Society of Mechanical Engineers 2004 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.18 No.11
The design of a reliable and failsafe control system requires that sensor failures be detected and identified within acceptable time limit so that system malfunction can be prevented. This paper presents a model-based approach to sensor fault detection with applications to vehicle stability control systems. The effectiveness of the proposed method is illustrated through test data-based evaluation. Vehicle test data-based evaluation results show that the proposed fault management scheme can be used for the design of a failsafe VSCs.
Design of a Full-range ACC with Collision Avoidance Braking
Kyongsu Yi,Kyoungjun Lee,Seung-Wuk Moon,In-Sik Lee,Jae-Yong Um,Ilki Moon 한국자동차공학회 2006 한국자동차공학회 Symposium Vol.- No.-
This proposes a design methodology for a full-range ACC (Adaptive Cruise Control) with collision avoidance braking. The control scheme is designed to control the vehicle so that it would feel natural to the human driver and passengers during normal safe driving situations, to completely avoid collision in vehicle following situations and to reduce the severity of collisions in unexpected emergency situations. Driving situations are determined by using a non-dimensional warning index and time-to-collision (TTC). The proposed control scheme can provide natural following performance similar to human manual driving in both high speed driving and low speed stop-and-go situations and can prevent vehicle collision in dangerous traffic situations such as severe braking of the preceding vehicle during a vehicle following situation.

The peak dynamic tire loads. which are greatly in excess of static loads. are highly dependent on the dynamic characteristics of vehicle suspensions. Analytical research has shown that the vehicle-generated pavement damage can be reduced by using more advanced suspensions. This paper describes a proposed semi-active suspensions for heavy vehicles to reduce the dynamic tire forces. Simulation studies are presented to compare the performance of the advanced suspensions with the four leaf tandem suspensions.<br/>
