Available in PDF, EPUB and Kindle. Book excerpt: The demands imposed by the optimal design process form a unique set of criteriafor the development of a computational model for vehicle simulation. Due to the largenumber of simulations that must be performed to obtain an optimized design the modelmust be computationally efficient. A competing criterion is that the computational modelmust realistically model the vehicle. Current trends in vehicle simulation codes have tackled the problem of realism byconstructing elaborate full vehicle models containing dozens if not hundreds of distinctbodies. Each body in a model of this type is associated with six degrees of freedom. Numerous constraint equations are applied to the bodies to represent the physicalconnections. While the formulation of the equations is not particularly difficult, and in facthas been automated in several software packages, the resulting model requires aconsiderable amount of computational time to run. This makes the model unsuitable forthe application of computational optimal design techniques. Past research in the field of vehicle dynamics has produced numerouscomputational models which are small enough and fast enough to satisfy the speeddemands of the optimal design process. These models typically use less than a dozendegrees of freedom to model the vehicle. They do a good job of predicting the generalmotion of the vehicle and they are useful as design tools but they lack the accuracyrequired for optimal design. A model that bridges the gap between these two existing classes of models and issuitable for performing optimal design was developed. The model possesses twenty-eightdegrees of freedom and consists of eight bodies which represent the sprung mass, the rearsuspension, the left front spindle, the right front spindle, and the four wheels. A drivercontrol algorithm was developed which is capable of driving the car near its handlinglimits. The NCSU Legends race car was modeled and an attempt was made to optimizethe vehicle setup for the Kenley, NC.

This book was released on 2010 with total page 205 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: As safety continues to take an increasingly important place in the automobile industry, there has been significant research and development in the area of closed loop control of vehicle dynamics. It first started with antilock brake systems (ABS) that prevented loss of steering control due to wheels locking up with hard braking or low friction. Vehicle dynamics control further developed to include traction control: a system that optimally distributes tractive forces and prevents excessive wheel slip. The most recent developments have been in the area of electronic stability control (ESC). As vehicle technology has evolved over the years and ABS and ESC are now becoming standard on most vehicles, not only automobile manufacturers but even governments and regulation bodies have programs dedicated to ensure standards and understand limitations of these systems. As a result, efforts have been made to develop testing systems and test maneuvers to quantify dynamic properties. This research focuses on studying standard maneuvers and developing new strategies to evaluate and rate the performance of modern vehicles equipped with advanced vehicle dynamic control systems. Another significant development of the last decade is autonomous (or unmanned) vehicles. An important application of autonomous vehicles is automated test drivers, which are systems that replace human drivers in vehicle dynamic testing. This increases the reliability and repeatability of test maneuvers, which is imperative for dependable results in some specialized maneuvers. Most vehicle dynamic tests involve precise actuation of steering wheel or brake/throttle pedals. Steering controllers and braking robots are designed to do just that. One such system designed by SEA, Ltd and used extensively by OSU researchers, has been demonstrated to perform various standard tests accurately for a wide range of vehicles and is also used by various organizations worldwide. In this research the areas of vehicle dynamics control and autonomous vehicles come together; the automated test driver is developed to execute path-following maneuvers to evaluate the performance of vehicle dynamics controllers, including those used in ESC, in evasive driving situations. During evasive maneuvers the tire forces are no longer a linear function of slip angles and the vehicle response is nonlinear and potentially unstable, a condition which the active stability systems are designed to mitigate. The definition of understeer gradient in the linear-range does not lend itself to analysis of nonlinear-range dynamics. Another focus of this research is to assess stability and controllability based on estimation of tire forces. A vehicle observer is designed for the purpose of detecting and measuring understeer and oversteer in dynamic maneuvers. The method can be used to benchmark a vehicle regardless of passive or active control. As an extension of the autonomous steering control problem, this project involves the study of application of active steering for vehicle stability control. Control algorithms are developed that use the information from tire force estimator and driver intent models to yield linearized and predictable vehicle lateral response by an active steering system. This research brings together the development of an automated test driver, active vehicle motion control systems and testing for dynamic stability by using tire force estimation.

This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent vehicle developments are forced by continuously decreasing development times. To reach this aim virtual methods are necessary. Concerning the research area of vehicle dynamics, virtual analyses play an important role during the whole development process of a vehicle. Vehicle dynamics simulations using different manoeuvres, models and environments become a key component. This important role is even more significant for the early design phase of the vehicle, where only few and uncertain parameters are available. The present thesis expands the simulation platform MOVES2, designed for modular vehicle dynamic simulations during the early design phase, at the Institute of Automotive Engineering at Graz University of Technology. The presented expansion implements a set of modules to generate arbitrary roads within arbitrary scenarios, to animate the simulated vehicle motion within a virtual reality world based on the generated scenario, to define the desired trajectory for the simulation and to configure the modelling complexity of the model. To ensure a high level of user-friendliness, the Graphical User Interface of MOVES2 manages the required data from these modules, by creating, editing and deleting it.

Available in PDF, EPUB and Kindle. Book excerpt: In this dissertation, a group of vehicle dynamics simulation tools is developed with two primary goals: to accurately represent vehicle behavior and to provide insight that improves the understanding of vehicle performance. Three tools are developed that focus on tire modeling, vehicle modeling and lap time simulation. Tire modeling is based on Nondimensional Tire Theory, which is extended to provide a flexible model structure that allows arbitrary inputs to be included. For example, rim width is incorporated as a continuous variable in addition to vertical load, inclination angle and inflation pressure. Model order is determined statistically and only significant effects are included. The fitting process is shown to provide satisfactory fits while fit parameters clearly demonstrate characteristic behavior of the tire. To represent the behavior of a complete vehicle, a Nondimensional Tire Model is used, along with a three degree of freedom vehicle model, to create Milliken Moment Diagrams (MMD) at different speeds, longitudinal accelerations, and under various yaw rate conditions. In addition to the normal utility of MMDs for understanding vehicle performance, they are used to develop Limit Acceleration Surfaces that represent the longitudinal, lateral and yaw acceleration limits of the vehicle. Quasi-transient lap time simulation is developed that simulates the performance of a vehicle on a predetermined path based on the Limit Acceleration Surfaces described above. The method improves on the quasi-static simulation method by representing yaw dynamics and indicating the vehicle's stability and controllability over the lap. These improvements are accomplished while maintaining the simplicity and computational efficiency of the two degree of freedom method.
