Four-Wheel Steering Autonomous Vehicles
Volume 10: Mechanical Systems and Control, Parts A and B, 2009Employing an independent four-wheel-steering (4WS) system, we introduce an autodriver algorithm to keep an autonomous vehicle on a given road. The kinematic condition of steering can be used to set the steer angles such that the kinematic center of rotation is at a desired point.

Dynamics of four-wheel-steering vehicles
Forschung im Ingenieurwesen, 2001In this paper we present an optimised 3 degrees-of-freedom non-linear dynamic model of a four-wheel-steering (4WS) vehicle. As variables, we retain the lateral velocity V, the rolling velocity p and yaw velocity r. The front steer angle δf and rear steer angle δr are considered to be linear functions of the steering wheel angle θs and of dθs/dt, the ...

Behavior-based steering control for four wheel independent steering vehicle
2008 IEEE International Conference on Robotics and Biomimetics, 2009This paper proposed a behavior-based steering controller for four wheel independent steering vehicle. The proposed controller acts as virtual linkages among each wheel to minimize wheel slip resulted by the misalignment of the orientations of wheels effectively. As there is no trajectory planning needed in the control algorithm, the proposed controller

A Motion Controller for Compliant Four-Wheel-Steering Robots
2006 IEEE International Conference on Robotics and Biomimetics, 2006This paper proposes a behaviour-based approach for the motion control problem of sustainable and compliant Four-Wheel-Steering robots. Each wheel is considered to be an independent entity that must react according to some local rules. Motivated by the Virtual Components Approach, behaviours implement these local rules by means of a set of virtual ...

Journal of Intelligent & Fuzzy Systems, 2016
In this paper, we study a four-wheel, individual steering and four-wheel, individually driven, electric chassis, named the flexible chassis. A 2-FOF nonlinear steering model for the flexible chassis is established based on the “magic formula” tire model and the Ackermann steering theorem at low speed.

Omni-directional steer-by-wire interface for four wheel independent steering vehicle
2009 IEEE International Conference on Robotics and Automation, 2009In this paper, an omni-directional steer-by-wire interface for four wheel independent steering vehicle is presented. The proposed steering interface is an extension of a traditional steering interface that provides three steering inputs. By combination of which, driver can control the vehicle in traditional way or omni-directionally without any mode ...

Optimizing Design of Four-Wheel Steering Vehicle Steering Trapezoid Based on MATLAB
2011 Second International Conference on Digital Manufacturing & Automation, 2011This article designed a steering trapezoid of four-wheel steering construction vehicles with the MATLAB optimization toolbox. It solve out the relationship between the inside steering angle and outside steering angle in actual, to make the difference between the angle of inside wheel rotation in theoretical and angle of inside wheel rotation in actual ...

Design of Optimal Four-Wheel Steering System
Vehicle System Dynamics, 1995SUMMARY Optimal design of the four wheel steering (4WS) system of the ground vehicle is studied. 4WS vehicles with the optimal control scheme are considered first. General formulation of the optimal control law is developed based on the linear quadratic regulator theory.
