This book was released on 2014 with total page 109 pages. Available in PDF, EPUB and Kindle. Book excerpt: An integrated vehicle controller is presented for electric vehicles using independently driven wheel motors. This topology takes an optimal control approach to enhancing a vehicle's performance, stability, and energy consumption metrics simultaneously in a unified software structure. The logical output of this algorithm is a set of re-distributed wheel torques, to create torque vectoring for stability-focused yaw rate tracking, and longitudinal biasing to modify motor load for energy savings. A real-time numerical approach to solving the optimization problem is also presented, and shown to offer benefits over a closed form analytic approach. In this, solution constraints are used to link considerations such as nonlinear motor limits, tire friction envelopes, and lower-level traction control loops. To test the efficacy of this control structure, two vehicle test platforms were constructed as retrofits of production gas SUVs for electric drive. For this, the component layout is given, followed by an explanation of the software code structure as performed in a Simulink/Carsim/dSpace environment. Results from these platforms are given, with experimental and simulation data for traction control, yaw performance tracking and drive cycle power consumption. Proven performance over a variety of maneuvers and surface conditions further demonstrate the controller's stability and suitability for mass production.

Available in PDF, EPUB and Kindle. Book excerpt: Upon the ongoing profound revolution in the automotive industry, this book is primarily intended to give guidance on the practical design of traction motor control for pure electric vehicles (EVs) and hybrid electric vehicles (HEVs). An overview of the state-of-the-art motor types is provided to help understanding the background of automotive motor drives and the EV/HEV motor control specifications. Using AC induction motor control as a benchmark example, it addresses the motor control techniques by means of design, analysis, examples with MATLAB scripts wherever applicable, and practical control software architecture diagrams. In particular, an extensive analysis and discussion are made on the widely used vector control method together with multiple optimization schemes. As such, it gives coverage of the electric traction control including dynamics, efficiency, and the high-speed power capability, taking into account the constraints of vehicle configuration and requirements. The vector control and optimization strategies presented in this book can be ported across to other AC motor types without losing much generality. This book tries to bridge the gap between theory and practicality. Beginning with basic motor theory and completing the motor control design by introducing voltage source inverter (VSI) pulse width modulation (PWM) techniques, it helps the reader take a step-by-step approach from understanding fundamental motor characteristics through to practical design of in-depth motor control strategies.

This book was released on 2018 with total page 115 pages. Available in PDF, EPUB and Kindle. Book excerpt: Electric Vehicles (EVs) develop high torque at low speeds, resulting in a high rate of acceleration. However, the rapid rise in torque of an electric motor creates undesired torsional oscillations, with vehicle jerk arising as a result of wheel slip or flexibility in the half-shaft. These torsional oscillations in the halfshaft lead to longitudinal oscillations in the wheels, thus reducing comfort and drivability. In this research, we have designed an anti-jerk longitudinal dynamics controller that damps out driveline oscillations and improves the drivability of EVs with central-drivetrain architecture. The anti-jerk longitudinal dynamics controller has been implemented for both traction and cruise control applications. We have used a model predictive control (MPC) approach to design the controller since it allows us to deal with multiple objectives in an optimal sense. The major scope of this research involves modeling, parameter identification, design and validation of the longitudinal dynamics controller. The real-time implementation has been demonstrated using hardware-in-the-loop experiments utilizing fast MPC solvers. The MapleSim software, which utilizes symbolic computation and optimized-code generation techniques to create models that are capable of real-time simulation, has been used to develop the longitudinal dynamics plant model. Road tests have been conducted on our test vehicle, a Toyota Rav4 electric vehicle (Rav4EV), to identify the parameters for the longitudinal dynamics model. Experimental data measured using a vehicle measurement system (VMS), global-positioning system (GPS), and inertial measurement unit (IMU) was used for parameter identification. Optimization algorithms have been used to identify the model parameters. A control-oriented model of the EV, which includes a flexible halfshaft and effect of wheel-slip transients, has been developed with the aim of controlling driveline oscillations. The MPC-based anti-jerk traction controller regulates the motor torque corresponding to the accelerator pedal position, to serve the dual objectives of traction and anti-jerk control. The performance of this controllers has been compared to that of other controllers in the literature. Since most traction controllers are on-off controllers and are only activated when wheel slip exceeds a desired limit, they are not effective in anti-jerk control. The MPC-based anti-jerk controller is able to serve multiple objectives related to anti-jerk as well as traction, and is therefore superior to other controllers. A unified design combining the upper and lower level MPC-based cruise controller has also been formulated to meet the anti-jerk objective during cruise control. The cruise controller has been designed such that it is adaptive to changes in road friction conditions. The efficacy of both traction and cruise controllers has been demonstrated through model-in-the-loop simulation, and the real-time capability has been demonstrated through hardware-in-the-loop experiments.

This book was released on 2016 with total page 125 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is a growing need for active safety systems to assist drivers in unfavorable driving conditions. In these conditions, the behavior of the vehicle is different than the linear response during everyday driving. Even experienced drivers usually lose control of the vehicle in such situations and that often results in a car accident. Stability control systems have been developed over the past few decades to assist drivers in keeping the vehicle under control. Most of these control systems are comprised of separate modules, each responsible for one task such as yaw rate tracking, sideslip control, traction control or power distribution. These objectives may be in conflict in some driving situations. In such cases, individual controllers fight over priority and produce conflicting control commands, to the detriment of the vehicle performance. In addition, in most stability control systems, transferring the controller from one vehicle to another with a different driveline and actuator configuration requires significant modifications in the controller and major re-tuning to obtain a similar performance. This is a major disadvantage for auto companies and increases the controller design and tuning costs. In this thesis, an integrated control system has been designed to address vehicle stability, traction control and power distribution objectives at the same time. The proposed controller casts all of these objectives in a single objective function and chooses control actions to optimize this objective function. Therefore, the output of the integrated controller is not altered by another module and the optimality of the solution is not compromised. Furthermore, the designed controller can be easily reconfigured to work with various driveline configurations such as all-wheel drive, front or rear-wheel drive. In addition, it can also work with various actuator configurations such as torque vectoring, differential braking or any combination of them on the front or rear axles. Moving from one configuration to another does not change the stability control performance and major re-tuning can be avoided. The performance of the designed model predictive controller is evaluated in software simulations with a high fidelity model of an electric Equinox vehicle. The stability and wheel slip control performance of the controller is evaluated in various driving and road conditions. In addition, the effect of integrated power distribution is studied. Experimental tests with two different electric vehicles are also carried out to evaluate the real-time performance of the MPC controller. It is observed that the controller is able to maintain vehicle and wheel stability in all of the driving scenarios considered. The power distribution system is able to improve vehicle efficiency by approximately 1.5% and acts in cooperation with the stability control objectives.
