Co-simulation and simulation integration for a full vehicle dynamic system

Abstract

The electric power steering (EPS) mechanism ensures improved vehicle safety and fuel economy. The development of a concurrent simulation technique and a simulation integration technique for analysing an EPS control system with a dynamic vehicle system is described in this paper. A full vehicle model interacting with an EPS control algorithm was concurrently simulated on a single-bump road condition. The dynamic responses of the vehicle chassis and the steering system resulting from impact with the road surface were evaluated and compared with experimental data obtained at the proving ground. Reasonable agreement was obtained for tie-rod load, rack displacement, steering wheel torque, and tyre centre acceleration. The concurrent simulation capability was employed for EPS performance evaluation and calibration as well as for vehicle-handling performance integration and synthesis.

An experimental comparison of mathematical heavy-duty city bus models to evaluate passenger ride comfort induced by road roughness

“…Vehicle dynamics models have long been developed for different purposes such as to design and optimize suspension system [6,7], to evaluate passenger ride comfort and vehicle handling [8,9], and to evaluate road roughness conditions [10,11]. Multibody dynamical models have been used intensively [12,13] but require a massive amount of data and computation efforts. Regarding mathematical models and road roughness evaluation, the most commonly used vehicle models are quarter-car-simulation (QCS), half-car-simulation (HCS) and full-car-simulation (FCS), of which the QCS has been used most often due to its simplicity.…”

“…This study focuses on the fundamental interactions between road, vehicle and passenger. Using simpler methods entail less data on vehicle dynamics, and the industry can more readily apply the results for pavement engineering application such as to evaluate road surface conditions [13,14].…”

The Auto control System Based on InTouch Configuration software for High-gravity Oil Railway Tank Feeding

“…In the articles [1][2][3], the Intouch software is composed with Matlab to cope with the vision and image, the method was very useful. Cosimulation and simulation integration for a full vehicle dynamic system [4,5], toward a model integration methodology for advanced application in power engineering [6] have been developed. The direct communication between Matlab and Intouch, design and application of Intouch in cold tandem mill control system were presented in the articles [7,8].…”
