9437944 Mobility of Vehicle as a Living Creature Rakuzo Mitamura (Mitsubishi Motors Corp./Japan), pp. 1-8, 15 figs., 7 refs. Recent development of automobile technologies has exhibited remarkable achievements in a couple of areas, namely mechanical innovations and the electronic ones. These innovations tend to open new scope for self-control functions of the vehicle itself. Thus the driver's roll which has been deemed as a burden, is basically reduced and replaced with driving fun and comfort. There are, however, several areas which need further research and development. The first is further enhancement of dynamic limit of vehicle. The second is how to define the driver's roll if most of the operations can be done within the vehicle. The third, as the result, is bow to negotiate the interference of operations made by the driver and the vehicle in critical situations. This paper introduces some of the proposed approaches to cope with the situations. 9437953 Active Safety of Commercial Vehicles Egon-Christian von Glasner (Mercedes-Benz AG/Germany), pp. 9-14, 8 figs., 7 refs. To satisfy increasing demands on active safety, commercial vehicle manufacturers have enormously intensified their efforts in developing intelligent systems for the dynamic and, notably, for the braking performance of commercial vehicles. This has given rise in the past few years to new, electronic vehicle management systems which will significantly enhance the active safety of commercial vehicles in daily on-the-road service [1]. The subject "Electronic Vehicle Management Systems" has not been much discussed in public to date as the related possibilities which it offers for increasing the active safety of commercial vehicles are still relatively unknown. 9437962 Evaluation of Vehicle Vibration M. Mitschke (Technische Universifiit Braunschweig/Germany), pp. 15-21, 6 figs., 7 refs. In order to evaluate vehicle vibrations it is necessary to know about the human response to vibration excitation. Some new weighting functions for harmonic and random vibration will be presented. Each vibration input point like seat, hands and feet has its own weighting function. The overall weighting is calculated according to the presented summation equation. The impact parts of vibration forms are additionally weighted and considered. Regression analysis shows another method of analysing the relations between human vibration response and physical characteristics. 9437971 Application of AR-method to Dynamic Identification of Driver-Vehicle System in Lane Change Hitoshi Soma, Kaneo Hiramatsu (Japan Automobile Research Institute, Inc./Japan), pp. 22-27, 13 figs., 1 tables, 5 refs.
One of technologies of advancing motion control may be an advanced control using real or quasi-real time supervision of driver-vehicle systems, a kind of closed-loop systems. In this supervision, however, it is necessary to identify and separate characteristics of driver, vehicle and controller from data of short duration, almost continuously. In this paper, regarding this identification, the AR-method was applied to the case of lane changes. As a result of the analysis, the AR-method was verified with respect to identification from the data of short duration in lane changes. 9437980 Control Loop for Driver-Vehicle with Four Wheel Steering M. Mitschke, E. Ahring (Technische Universitiit Braunschweig/ Germany), pp. 28-35, 8 figs., 2 tables, 10 refs. Due to the variation of load or weather condition the driver has to adapt himself to the different vehicle handling characteristics. This report points out how the change of those handling characteristics can be reduced through a rear-wheel and additional front-wheel steering. For that reason the drivers adaption to the control loop is not necessary, an increase in safety is possible. 9437999 Characterization of Driver-Vehicle Directional Control Using Three Models of Human Driver Mostafa S. Habib (University of Bahrain/Bahrain), pp. 36-41, 13 figs., 11 refs. This article presents the simulation of driver-vehicle directional control criteria using three models of human driver. The vehicle is represented by a two degrees of freedom mathematical model to describe the yaw and lateral motion. The three models of driver behaviors considered in this study are: the lead compensator with time delay, the composite lateral and heading feedback compensator and the so called "structural model" of the human operator. Simulation study of the closed loop system is used to characterize the three models with respect to stability and performance. A proposed driver model is presented. 9438006 Theoretical Investigations of the Interaction Driver.Feedback-Controlled Automobile Manfred Plfichl, Peter Lugner (University of Technology, Vienna/Austria), pp. 42-48, 15 figs., 11 refs. For this investigation a complex 4-wheel vehicle model of a passenger car is used that includes a detailed steering system and drive train. The type properties are described for all possible combined longitudinal and lateral slip values and for arbitrary friction conditions. The active part is an additional steering system of all 4 wheels, additionally to the driver's steering wheel angle input. Three control levels are used for the driver model that thereby can follow a given trajectory or avoid an obstacle.
