Roll-Over Prevention System for Commercial Vehicles – Additional Sensorless Function of the Electronic Brake System

Recent experiences have shown that even small-medium size passenger cars face an accident which has been connected with commercial vehicles so far: the roll-over. The roll-over is the most horrible accident type for truck drivers, since he/she does not have any indication before it happens, and consequently does not react properly. This article discusses some of the problems of the commercial vehicle stability in general, and offers a solution for detecting and avoiding roll-over by using the existing sensors and actuators of electronic brake system (EBS).

Gravity center height estimation for the rollover compensation system of commercial vehicles

This paper concerns a technology to estimate the vehicle dynamics transfer function and to correct the control parameter of roll-over compensation system. ARX-model is applied to estimate the transfer function of an actual vehicle. The gravity center height, one of the control parameters of the control model, is corrected so that the transfer function could be in congruence with that of the actual vehicle. The control model forecasts the critical roll-over condition and the control system compensates the critical condition by controlling the braking force distribution.

Tyre pressure monitoring using a dynamical model-based estimator

In the last few years, various control systems have been investigated in the automotive field with the aim of increasing the level of safety and stability, avoid roll-over, and customise handling characteristics. One critical issue connected with their integration is the lack of state and parameter information. As an example, vehicle handling depends to a large extent on tyre inflation pressure. When inflation pressure drops, handling and comfort performance generally deteriorate. In addition, it results in an increase in fuel consumption and in a decrease in lifetime. Therefore, it is important to keep tyres within the normal inflation pressure range. This paper introduces a model-based approach to estimate online tyre inflation pressure. First, basic vertical dynamic modelling of the vehicle is discussed. Then, a parameter estimation framework for dynamic analysis is presented. Several important vehicle parameters including tyre inflation pressure can be estimated using the estimated states. This method aims to work during normal driving using information from standard sensors only. On the one hand, the driver is informed about the inflation pressure and he is warned for sudden changes. On the other hand, accurate estimation of the vehicle states is available as possible input to onboard control systems.     

A numerical study of the derailment caused by collision of a rail vehicle using a virtual testing model

This study investigated the wheel-lift and roll-over derailment mechanisms caused by train collisions using a precise virtual testing model (VTM) of a Korean high-speed train. The VTM was a complex, nonlinear finite element model composed of the shell, beam, solid, spring, and surface contact elements for the car body, bogies, suspensions, and wheel–rail interfaces. The VTM was validated by checking the errors in the total energy and the dynamic responses of the spring elements. To achieve a quick, dynamic relaxation of the dead weight of the VTM before the collision analysis, the artificial damping method and the artificial force method were introduced and numerically evaluated. The surface-to-surface contact model from commercial software, Ls-Dyna, was applied to the VTM in order to simulate the derailment mechanisms caused by collision accidents. The numerical analyses of the VTM colliding with a large deformable obstacle or a rigid wall revealed for the first time that a mixed slip/roll-over-type derailment mechanism generally occurs. Furthermore, the simulation results were consistent with the results from a simplified theoretical derailment model of a wheel set.
