In the early stage of the vehicle development, the analysis and test of the K&C (Kinematic & Compliance) characteristics are very important because we are able to expect the R&H performances through their parameters. They are measured by SPMD (Suspension Parameter Measurement Device) and usually simulated by ADAMS. Nowadays it is required to get more accurate solutions of the K&C characteristics. So in this paper we study on the modeling methods for K&C analysis. It starts by using flexible model of the suspension parts like knuckle.

This paper describes an investigation into coordinated control of electronic stability control (ESC) and active roll control system (ARS). The coordinated control is suggested to improve the vehicle stability and agility features by yaw rate control. The proposed integrated chassis control algorithm consists of a supervisor, control algorithms, and a coordinator. The supervisor monitors the vehicle status and determines desired vehicle motions such as a desired yaw rate and desired roll motion based on control modes to improve vehicle stability. According to the corresponding the desired vehicle dynamics, the control algorithm calculated a desired yaw moment and desired roll moment, respectively. Based on the desired yaw moment and the desired roll moment, the coordinator determines the brake pressures and the ARC motor torques based on control strategies. Closed loop simulations with a driver-vehicle-controller system were conducted to investigate the performance of the proposed control strategy using CarSim vehicle dynamics software and the integrated controller coded using Matlab/Simulink.

SBW system have advantages of space and fuel efficiency because it is designed more simple than MDPS. But, The safety is accompanied because of simplification of the mechanical structure. So, Intensive evaluation of fault diagnosis and safety at the development phase is needed. This research introduce a steering reaction HILS for evaluation in various driving conditions. The reaction equipment have to added because there is no connection between Rack and pinion. Reaction force is generated by servo motor and the control value of reaction force is realized by Rack force model using CarSim and Matlab/simulink. The Rack force is estimated by longitudinal force and lateral force of tires. As a result we can obtain steering feeling similar to data of real vehicle adapted EPS.

Crosswind is one of the major factors that affects on driving stability. Therefore, in order to make up for it, the performance evaluation for MDPS which assist to ensure vehicle driving stability is very important. But the driving stability evaluation of vehicle system for crosswind is difficult to take a vehicle test due to environment restriction. In this paper, we want to develop the method and criteria of evaluating driving stability for crosswind of MDPS with HiLS quantitatively. The purpose of this study is to help the vehicle development by reviewing and applying for the method which can evaluate driving stability for crosswind under various condition in virtual driving environment based on MDPS HiLS.

본 연구에서는 By-Wire System중의 하나인 Brake-by-Wire 시스템에 대한 실차 시험을 기반으로 동적성능을 평가하기 위한 평가방법을 제안하였다. BbW 시스템은 유압에 의한 제동력을 모터의 토크로 대체한 시스템이다. BbW 시스템은 운전자의 브레이크 페달 입력을 기준으로 목표 제동토크 생성 동력원인 모터, 모터와 캘리퍼 사이에 배력을 위한 기구요소 및 이를 제어하기 위한 모터제어기로 구성된다. 더불어 기존의 유압제동시스템과 동일한 조작감을 생성하기 위한 페달 에뮬레이터를 장착하였다. BbW 시스템이 장착된 차량을 이용하여 제동시험을 수행하였고, 얻은 결과를 토대로 힘 제어 응답성, 위치 제어 응답성 평가지수를 개발하였다.
