Abstract: By utilizing the electric motor as the propulsion system, the electric vehicle (EV) establishes a new bridge between renewable energies and our daily life, which meanwhile has to face with a brand new technical issue, namely the energy management and conversion. Then, the performance of energy conversion systems has become a new evaluation criteria for EVs. Accordingly, this study works on the analysis and control of the EV energy conversion system, including the secure charging system via wireless power transmission (WPT), advanced driving control via electric propulsion system, and bidirectional power interface via electromagnetic interference (EMI) mitigation technique. First, this study proposes a novel energy encryption algorithm for WPT systems. In the presented scheme, the energy can be encrypted by chaotically regulating the frequency of the power source based on the unpredictable security key. The authorized receptor can effectively receive the energy by simultaneously adjusting the circuit to decoding the encrypted energy based on the acquired security key, while the unauthorized receptor cannot obtain the energy without knowledge of the security key. In this study, both simulation and experimental results are provided to verify the feasibility of the proposed secure WPT system. Subsequently, this study proposes a new dynamic model of EV powering steering systems, by synthetically taking into account characteristics of the electric propulsion motor, driver's operation, and uncertain disturbances caused by irregularities of the road surface. By using various nonlinear analysis methods, the unstable chaotic behaviors can be revealed in the power steering system, especially when the vehicle turns a concern at a high speed. Additionally, a new control algorithm is designed and implemented to stabilize the EV power steering system, and corresponding validity is also mathematically proved in this study. Thirdly, an integrated driving control system is designed based on the aforementioned dynamic analysis, which is used to enhance the stability and maneuverability performances of four-in-wheel independently-driven (4WID) EVs. By adopting the supervisor-actuator structure, the proposed driving control scheme not only effectively improves the performance of tracking reference paths, but also optimally distribute the desired yaw moment to each in-wheel motor. In this study, the mathematical proof and the simulation are both conducted to demonstrate the feasibility of the proposed integrated driving control strategy. Lastly, this study also works on the EMI issue caused by switch-mode energy conversion devices for EVs. In this section, a new pulse-width-modulation (PWM) method is designed by utilizing the random-like sequence, aiming to suppress the conducted peaky EMI over the whole power spectrum, thereby ensuring the working performance for electronic instruments in EVs. For demonstrating the effectiveness of the proposed soft-chaoizing scheme, this study takes two exemplifications such as the electric propulsion drive system and the bidirectional power interface for vehicle-to-grid (V2G) systems.

Download or read book Development of a Vehicle Stability Control Strategy for a Hybrid Electric Vehicle Equipped with Axle Motors written by Kerem Bayar and published by . This book was released on 2011 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Hybrid-electric vehicles have been available to consumers for over a decade, and plug-in hybrid and pure electric vehicles are rapidly becoming mainstream products with the introduction of vehicles such as the Chevrolet Volt and the Nissan Leaf in 2011. These vehicles have in common an electric powertrain, comprised of one or more electric motors and of a battery pack which in the case of hybrid vehicles supplements and internal combustion engine. It is well understood that hybrid and electric vehicles have the benefit of significant reduction in CO2 emissions and in the use of petroleum as a fuel. However, one additional benefit of hybrid and electric vehicles remains so far under-utliized: the use of the electric traction system to enhance vehicle stability control. This potentially or low cost feature could provide additional motivation for customers to choose hybrid or electric vehicles over conventional ones. This dissertation documents the conception and development of a novel control strategy to allocate braking and tractive forces in a hybrid electric vehicle equipped with axle motors, for the purpose of enhancing the vehicle stability control system. The work described in this dissertation documents the development of a hierarchical control strategy, its design and stability proofs, and its evaluation using software and model in-the-loop methods. The work includes the development of a dynamic HEV simulator that is capable of evaluating vehicle dynamics responses during emergency maneuvers, to demonstrate its stability. For this purpose, a hybrid powertrain simulation model including batteries, motors, differential, shaft, wheel, and electro-hydraulic brake system models are developed. Furthermore, a simple yet reliable vehicle dynamics model is integrated with the powertrain model to capture longitudinal, lateral, yaw and roll degrees of freedoms of the vehicle. The development of the simulator is a minor, but an original contribution of this dissertation. The principal contribution of this work is a novel and systematic vehicle stability control (VSC) strategy that distributes the corrective longitudinal force and yaw moment action to generate individual wheel slip ratios by blending regenerative axle motor braking and/or traction with individual wheel braking; so as to track the desired vehicle speed and yaw rate without causing excessive vehicle sideslip angles. This dissertation shows that including the axle electric motors within the proposed VSC frame, improves the performance of vehicle stability control in comparison to production vehicle VSC strategies. The potential benefit of electric motors, namely their ability to provide rapid braking/tractive torque actuation, is utilized in addition to the friction brakes within the proposed VSC scheme. The resulting strategy is the first published result that shows that yaw tracking and vehicle stabilization can be performed without interfering in the driver's longitudinal speed demand. Furthermore, the strategy limits the yaw rate in order to keep the vehicle sideslip angle in the safe range, by increasing the understeer coefficient whenever a sideslip angle safety threshold is exceeded. A secondary benefit of the proposed VSC scheme is its energy saving feature, thanks to the use of highly efficient electric motors and their regenerative braking capability in comparison to a standard vehicle stability control schemes that use only the brake and engine intervention. Finally, the proposed VSC strategy is tested in real time, by using a model-in-the-loop simulation set-up, using state-of-the-art hardware-in-the-loop computer systems. Model-in-the-loop simulation results for different road conditions and steering maneuvers showed that the proposed VSC performs satisfactorily in real time as well, suggesting that is amenable to in-vehicle implementation.
