And Control

As the four-wheel steering (4WS) system has great potentials, many researchers' attention was attracted to this technique and active research was made. As a result, passenger cars equipped with 4WS systems were put on the market a few years ago. This report tries to identify the essential elements of the 4WS technology in terms of vehicle dynamics and control techniques. Based on the findings of this investigation, the report gives a mechanism of electronically controlling the steering system depending on the variable pressure applied on it. This enhances the controlling and smoothens the operation of steering mechanism.

In this paper, the dynamics and control of an automated guided vehicle (AGV) is described. The objective is to control the vehicle direction and location with respect to a prescribed trajectory. This is accomplished based on an optimum control strategy using vehicle state variables. A four-wheel vehicle with three degrees of freedom including longitudinal, lateral and yaw motion is considered. The nonlinearity of the tire and steering mechanism is also included. The control system design for circular, straight forward and composite path is presented based on feedback linearization. Some trajectory simulation for discrete curvatures is carried out. The controller was implemented within MATLAB environment. The design was also evaluated using ADAMS full vehicle assembly. The results demonstrated the accuracy of the model and the effectiveness of the developed control system.

Most current urban vehicles are scaled-down versions of standard passenger cars. This imposes serious limitations on the safety, comfort, efficiency, dynamic performance and, hence, customer acceptance of the vehicle. This paper provides a unique design of an integrated corner module including an in-wheel suspension, an electrical in-wheel motor, a friction brake, a steering system, and a camber mechanism, which can be used in any urban vehicle design without modification. For the first time, a dual four-bar linkage mechanism has been designed to generate a virtual kingpin axis and provide an active camber. This approach results in a highly compact design for the corner module that can be integrated into narrow vehicles. A full-size prototype of the proposed integrated corner module has been fabricated and tested to validate the new steering mechanism and the integrated corner module characteristics.

Go-kart is one of the motor sports where racing of bunch of vehicles are compete each other. This paper is written after completion of manufacturing and complete assembly. Following paper consist of diagrams, calculations and results from actual models of steering and electrical systems. Steering system is one among crucial areas in designing of go kart as even the slightest of improvement in response of this technique could reduce the lap time and help to succeed in the driving force beyond the finishing line to win an edge. Thus, steering has got to be reliable enough such the driving force could have the entire control over the kart even within the toughest tracks. On the other hand, any failure in system could lead to serious injury or loss to the driver and the team. This paper is written with an aim to enhance a steering mechanism of go kart and overall responsiveness and control. This paper covers most of the concepts of steering mechanism of knowledgeable go kart. With the assistance of this paper one could understand and manufacture complete steering assembly individually. The paper consists of theory, formulae, calculations, diagrams and simulation results which give top to bottom understanding of knowledgeable go kart steering mechanism.

In this study, 2 DOF mathematical models of Pitman arm steering system are derived using Newton’s law of motion and modeled in MATLAB/SIMULINK software. The developed steering model is included with a DC motor model which is directly attached to the steering column. The Pitman arm steering model is then validated with actual Pitman arm steering test rig using various lateral inputs such as double lane change, step steer, and slalom test. Meanwhile, a position tracking control method has been used in order to evaluate the effectiveness of the validated model to be implemented in active safety system of a heavy vehicle. The similar method has been used to test the actual Pitman arm steering mechanism using hardware-in-the-loop simulation (HILS) technique. Additional friction compensation is added in the HILS technique in order to minimize the frictional effects that occur in the mechanical configuration of the DC motor and Pitman arm steering. The performance of the electronically actuated Pitman arm steering system can be used to develop a firing-on-the-move actuator (FOMA) for an armored vehicle. The FOMA can be used as an active safety system to reject unwanted yaw motion due to the firing force.
