Modeling and control of ground vehicles have become a major research field in the last few years, due to the increasing diffusion of driver assistance technologies and the persistent need for guaranteeing safety and comfort of driver and passengers. Although vehicle control systems require a large set of measurements to perform accurate computations, due to the possible unavailability and the non-negligible...
In this paper, the mathematical model of an electric vehicle, as well as the control system for avoiding pedestrians in urban traffic is described. The vehicle is modeled as a continuous system consisting of several subsystems. The discrete model of several sensors and actuators, a decision system, and low-level controllers for acceleration/braking and steering systems are added. Based on this model,...
This paper describes the development and validation of a control-oriented drivability model for an electric vehicle. The developed model is capable of predicting longitudinal vehicle responses that affect drivability. The model is useful for design, improvement and calibration of control algorithms. We simulate the model in Simulink and validate it by CRUISE. The simulation results demonstrate the...
For future mobility intended to decrease energy consumption by smaller and lighter body and also by applying low RRC (Road Resistance Coefficient) tires, there is a possibility that maneuverability and stability of such a vehicle will become reduced than current conventional vehicles. To solve this problem, a benchmark study is announced by ‘Committee of vehicle control and modeling research’ of JSAE...
This article briefly explains the lateral vehicle dynamics and upgrades a two wheel vehicle model adding the dynamics of roll, tire relaxation and wheels induced angles. The state equations of the resulting model are given. A bond graph model is build step by step from the resulting equations in order to have a base model to facilitate analysis, simulation and further developments.
