Articulated Wheeled Vehicles: Back to the Future?

Articulated Wheeled Vehicles (AWVs) are a class of wheeled locomotion systems where the chassis is connected to a set of ground-contact wheels via activelyor passively-controlled articulations, which can regulate wheel placement with respect to chassis during locomotion. The ensuing leg-wheeled systems exploit the reconfigurability and redundancy to realize significant benefits (improved stabil...

Autonomous terrain parameter estimation for wheeled vehicles

This paper reports a methodology for inferring terrain parameters from estimated terrain forces in order to allow wheeled autonomous vehicles to assess mobility in real-time. Terrain force estimation can be used to infer the ability to accelerate, climb, or tow a load independent of the underlying terrain model. When a terrain model is available, physical soil properties and stress distribution...

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...

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...
