This is a three-day course which provides a comprehensive and up to date introduction to fuel cells for use in automotive engineering applications. It is intended for engineers and particularly engineering managers who want to jump‐start their understanding of this emerging technology and to enable them to engage in its development. Following a brief description of fuel cells and how they work, how they integrate and add value, and how hydrogen is produced, stored and distributed, the course will provide the status of the technology from fundamentals through to practical implementation.
There is growing interest in the concept of a smart city and how these advanced technologies will improve the quality of living and make a city more attractive to visitors, commerce and industry. This course fills an unmet need for defining and explaining the relationship between connected and autonomous vehicles (CAVs) and smart city transportation. It is apparent that CAVs will achieve the best results when integrated with current and emerging urban infrastructure for transportation. This course addresses such integration from technology, organizational, policy and business model perspectives.
In this joint AIAA / SAE course, participants will learn about Electro-chemical Energy Systems (EES), with an emphasis on electrified aircraft propulsion and power applications. The course will present the fundamentals in chemistry, materials science, electrical, and mechanical engineering for various EESs including high voltage battery systems (Li-ion and beyond) and fuel cells (PEM, solid oxide fuel cells, and others).
This seminar will present an introduction to Vehicle Dynamics from a vehicle system perspective. The theory and applications are associated with the interaction and performance balance between the powertrain, brakes, steering, suspensions and wheel and tire vehicle subsystems. The role that vehicle dynamics can and should play in effective automotive chassis development and the information and technology flow from vehicle system to subsystem to piece-part is integrated into the presentation. Governing equations of motion are developed and solved for both steady and transient conditions.
Advanced Driver Assist System (ADAS) and autonomous vehicle technologies have disrupted the traditional automotive industry with potential to increase safety and optimize the cost of car ownership. Among the challenges are those of sensing the environment in and around the vehicle. Infrared camera sensing is seeing a rapid growth and adoption in the industry. The applications and illumination architecture options continue to evolve. This course will provide the foundation on which to build near infrared camera technologies for automotive applications.
Recently, there are lots of customers' requirements for future mobility such as narrow space movement, increased driving freedom, and ease of parking are emerging. And the key leading technologies to implement them are 4-Wheel independent Steering(4WS) technology. In this study, we will introduce the concept design approach of 4-corner steer module and how to prove the design. Last but not least, we defined the basic driving mode of 4WS and specified how to control the 4-corner steer module.
The transportation sector now faces several technological and societal challenges; the most urgent one is a shift to carbon-neutral mobility. One of the most efficient ways to reach this goal is car electrification. Vehicle corner architecture with an in-wheel motor is a promising stage of technological development for a new generation of electric vehicles. The state of art analysis indicates that a higher degree of integration between powertrain and chassis and the shift towards corner solution promises improved performances regarding new vehicle architecture design, energy efficiency, vehicle stability, reducing the overall system's weight. However, in-wheel mounted electric motor significantly increases unsprung vehicle mass; therefore, some undesirable impact on chassis loads and driving comfort occur.
The automotive industry is facing new emission regulations, changing customer preferences and technology disruptions. All have in common, that external aerodynamics plays a crucial role to achieve emission limits, reduce fuel consumption and extend electric driving range. Probably the most challenging components in terms of numerical aerodynamic drag prediction are the wheels. Their contribution to the overall pressure distribution is significant, and the flow topology around the wheels is extremely complicated. Furthermore, deltas between different rim designs can be very small, normally in the range of only a few drag counts. Therefore, highly accurate numerical methods are needed to predict rim rankings and deltas. This paper presents experimental and numerical results of four different production rim designs, mounted to a modified production car.
The Range Rover Evoque is a compact luxury SUV, first introduced by Land Rover in 2012. More than 800 000 units of the first-generation vehicle were sold. This paper explores some of the challenges entailed in developing the next generation of this successful product, maintaining key design cues while at the same time improving its aerodynamic efficiency. A development process is outlined, that made use of both numerical simulation and full-scale moving ground wind tunnel testing. By paying particular attention to the integration of active grille shutters, the front bumper and tyre package, and brake cooling along with underfloor design, wake control strategy and detail optimisation a drag coefficient of 0.32 was obtained for the best derivative, making it the most aerodynamic Range Rover to date. The impact of these development choices on the aerodynamic flow field and subsequently drag is highlighted.
