Preface Fundamental transformations are imminent for the automobile: propulsion technologies are going to shift from combustion engines to electric motors; cars will soon be safer than ever before; and traffic will become increasingly efficient on prospectively more intelligent roads. Currently, the most evident future trend is the electrification of the car, which means the replacement of two major building blocks of its propulsion system, the engine and the gas tank, by completely different technologies, namely an electric motor and a battery. One of the unique features of the electric power train is that it is controlled by electronic signals rather than by mechanical forces. The flow of energy and information between batteries, motors and wheels, and at the interface to the power grid can thus be managed by smart systems. So far, distributed functionalities can be easily integrated into one single subsystem, for example the intelligent wheel. This helps to optimize the energy efficiency and the driving range of the electric vehicle. Smart systems can successfully address challenges arising from the increased level of integration such as safe operation of a wheel carrying out acceleration, breaking and energy recovery functionalities at the same time. It is often said that electrification requires more information and communication technologies to be integrated into the car. However, it can also be seen as an opportunity to fundamentally review the electric and electronic architecture of the automobile, and to ge
