Written in English
The feedback control and modeling of a mobile robot with two wheels that are independently steerable and drivable is studied. Two-wheel steer vehicles increase their maneuverability when both wheels are powered and therefore increases their performance in confined spaces. A dynamic feedback control algorithm is developed, which enables the vehicle to move from any initial configuration (position and orientation) to any final configuration. Simulation results are presented to verify the independent control of the two position variables and the orientation variable. A comparison with a two-wheel steering and one wheel drive vehicle shows that driving both wheels increases performance and maneuverability.

Bogie designs Today, the majority of railway vehicles are equipped with bogies that contain mostly two axles, but in some cases, such as heavier and powerful locomotives, 3-axle designs are used. Because of the shorter axle distance of bogie designs, longer vehicles/vehicle sections can be used. On the other hand, the riding comfort of bogieFile Size: 1MB.

Vehicle Dynamic Control, or VDC, remains a specific feature installed in most known Nissan you check out the the Nissan Armada in MA, you are likely going to see advertisements for the feature, but if you don’t know what it does or how it functions, the knowledge of it being installed in the Nissan cars is not going to do you much good.
- If wheels or tires other than the recommended ones are used, the Vehicle Dynamic Control system may not operate properly and the Vehicle Dynamic Control off indicator light may come on. - The Vehicle Dynamic Control system is not a substitute for winter tires or tire chains on a snow covered road. vehicle . Kim and Han researched control methods improving the vehicle behavior by using optimization methods of longitudinal and lateral tire forces for six-wheeled vehicle.s Also, Lee et al. developed the maneuvering control system based on all-wheel independent driving and steering control for special purpose vehicles and proved the.

Optimal Vehicle Control of Four-Wheel Steering Victoria Schein Capstone Design Project Final Report May, Abstract Automotive vehicles call for a range of steering activity: one extreme is high-way driving with negligible turning.
Another is steering during U-turn maneuvers. This thesis is a preliminary investigation of the dynamics and control principles as applied to 2 Independent Wheel Drive (2IWD) vehicles. It will discuss the derivation of the dynamic models for a vehicle with independent drive wheels and variable front tire angles as well as the experimental validation of a fixed tire angle model.
Using mainly linear vehicle dynamic models as well as discussion of nonlinear limiting effects, Vehicle Dynamics, Stability, and Control, Second Edition answers these questions and more. It illustrates the application of techniques from kinematics, rigid body dynamics, system dynamics, automatic control, stability theory, and aerodynamics to 5/5(1).

The lateral stability of 8-axle vehicle can be improved by the direct yaw moment which is generated by the 16 independent driving wheels.
The hierarchical controller is designed to determine the required yaw torque and driving force of each by: 6. Vehicle Dynamics: Theory and Application is appropriate for senior undergraduate and first year graduate students in mechanical engineering.
The contents in this book are presented at a theoretical-practical level. It explains vehicle dynamics concepts in detail, concentrating on their practical use. Your Altima is equipped with a stability and traction control system called the Vehicle Dynamic Control (VDC).
The VDC system is designed to provide better traction during slippery driving by reducing engine output. This reduces wheel spin and can help get out of tight situations.
The wheels fitted to the object vehicle, not only support the vehicle weight while rotating and produce traction/braking forces, but also play a major role in making the motion independent from the tracks or guide ways.
This is the essential function of the vehicle. Start studying BASIC VEHICLE TECHNOLOGIES 2: CHASSIS. Learn vocabulary, terms, and more with flashcards, games, and other study tools.

As variables, we retain the lateral velocity V, the rolling velocity p. controlling the motion. Two independent driving wheels are used for position control, for fast motion in a plane without casters.
Two-wheeled machines have different applications due to their advantages which arise from their special design. For example, a two wheeled vehicle may be safer for the occupants while simultaneously being. The Vehicle Dynamic Control (VDC) system uses various sensors to monitor driver inputs and vehicle motion.
Under certain driving conditions, the VDC System helps to perform the following functions: Controls brake pressure to reduce wheel slip on one slipping drive wheel so power is transferred to a non slipping drive wheel on the same axle.
Nissan Vehicle Dynamic Control (or VDC) is the name of the stability control system found on Nissan's vehicles. The structure and principle of four-wheels independent driving and steering (4WIS-4WID) electric vehicle are presented firstly, and on this basis the structure of network control system base on CAN bus is built.
Kinematics and dynamics models of typical steering modes (such as all wheel steering, front (rear) wheel steering, parallel steering, zero-radius steering) are built, and the control Cited by: 2. Electronic stability control (ESC), also referred to as electronic stability program (ESP) or dynamic stability control (DSC), is a computerized technology that improves a vehicle's stability by detecting and reducing loss of traction ().
When ESC detects loss of steering control, it automatically applies the brakes to help "steer" the vehicle where the driver intends to go. Trihawk is a good example of a well-designed three-wheeler, in terms of dynamic stabiltiy. It's a 2F1R design with power delivered to the two front side-by-side wheels.
This means that more power can be delivered to the ground via the two powered front wheels. This paper present a detailed dynamic model of an electric vehicle with two independent wheel drives and an improved traction control system.
Using electric motors it is possible to have a torque control in each wheel drive, that enables the implementation of a traction control. This control level improves the stability and the safety of the.
