stability of three-wheeled vehicles with and without control system

Stability of Three-Wheeled Vehicles with and without Control System

In this study, stability control of a three-wheeled vehicle with two wheels on the front axle, a three-wheeled vehicle with two wheels on the rear axle, and a standard four-wheeled vehicle are compared. For vehicle dynamics control systems, the direct yaw moment control is considered as a suitable way of controlling the lateral motion of a vehicle during a severe driving maneuver. In accorda...

The Control and Stability Analysis of Two–wheeled Road Vehicles

The multibody dynamics analysis software, AUTOSIM, is used to develop automated linear and nonlinear models for the hand derived motorcycle models presented in (Sharp, 1971, 1994b). A more comprehensive model, based on previous work (Sharp and Limebeer, 2001), is also derived and extended. One version of the code uses AUTOSIM to produce a FORTRAN or C program which solves the nonlinear equation...

Optimum design of suspension system of three—wheeled motor vehicles∗

Three wheeled motorized vehicles play an important part in city transport of developing countries. In the present work, the results of an optimum design of suspension system using 9 degrees-of-freedom (DOF) analytical model for coupled motion of commercial three wheeled motor vehicles of Bajaj rear engine (RE) and Vikram front engine (FE) vehicle over road of various degree of measured roughnes...

Trajectory generation and control for four wheeled omnidirectional vehicles

This paper describes an algorithm to calculate near-optimal minimum time trajectories for four wheeled omnidirectional vehicles, which can be used as part of a high-level path planner. The algorithm is based on a relaxed optimal control problem. It takes limited friction and vehicle dynamics into account, as encountered in high-performance omnidirectional vehicles. The low computational complex...
