“…Other recent studies have focused on reductions in truck tare weight [17], waste heat recovery [5,[18][19], and limiting idle time [20][21][22]. Light-weight materials are crucial for truck quality, freight efficiency, cost saving and competitiveness [17]. Experiments and theoretical predictions indicated that an organic Rankine cycle (ORC) waste heat recovery system could yield significant fuel savings [5][6][18][19].…”

We present fuel savings estimates resulting from the combined implementation of multiple advanced energy management technologies in both conventional and parallel hybrid class 8 diesel trucks. The energy management technologies considered here have been specifically targeted by the 21 st Century Truck Partnership (21 CTP) between the U.S. Department of Energy and U.S. industry and include advanced combustion engines, waste heat recovery, and reductions in auxiliary loads, rolling resistance, aerodynamic drag, and gross vehicle weight. We estimate that combined use of all these technologies in hybrid trucks has the potential to improve fuel economy by more than 60% compared to current conventional trucks, but this requires careful system integration to avoid nonoptimal interactions. Major factors to be considered in system integration are discussed.

The current generation of automobiles is known for its sophisticated safety, comfort, and performance characteristics, which were developed in order to meet the ever-growing competition and advancement in the automotive field. Consequently, the development of smart materials with unique and exceptional properties is also gaining momentum. Of the various smart material currently applied in automotive technology, Shape Memory Alloys (SMAs), which boast the unique properties of shape memory effect and pseudo-elasticity, are steadily gaining popularity. The most prevalent automotive application of this material is in SMA actuators. These actuators are compact, lightweight alternatives to mechanical actuators, providing silent operation, enhanced reliability, durability, and resistance to humidity, shock, and vibrations. They are used in a variety of automotive systems such as adjustable mirrors, windshield wipers, door locks, smart bonnets, tumble flaps, governor valves, fog louvers, hatch vents, and many more. Among the various commercially available SMAs, Ni-Ti alloys are the most extensively used in most of these applications. This paper provides an overview of the properties, applications, and challenges of SMAs in the automotive sector.

Automotive transmissions are fundamental components in modern vehicles. They are required to make the engine operating at the most efficient operating point for providing the necessary torque at the wheels and minimizing the fuel consumptions. Moreover, transmissions should be able to smooth or to filter out power source torque oscillations that can appear in the driveline. For achieving such objectives, the automotive industry has looked at different technological solutions. The introduction of electronically controlled transmissions contributed to augment the possibilities of new solutions that would not have been implementable without the flexibility and the performance of electronic control. Thus, recent technological developments of automotive transmissions gave the opportunity to engineers and control scientists for investigating challenging control problems with daily life practical applications. Keywords IntroductionIn motor vehicles, the transmission is an important system that transfers the power generated by the internal combustion engine to the wheels, according to the driver's requests. The transmission, together with the engine, the driveshaft, differential, and driven wheels, constitutes the powertrain (Sometimes the term driveline is used to denote the powertrain excluding the engine and the transmission.) (or drive train). The first fundamental objective of a transmission is to adjust the ratio between the wheel speed and the engine speed in order to achieve the optimal operating point of the engine, independently on the vehicle velocity. Indeed, typical internal combustion engines provide low torques at low engine speeds, and, thus, it is necessary to amplify the torque making the engine work at higher speeds when the vehicle is at low speeds, e.g., during a launch from standstill. From an equivalent point of view, the transmission allows to amplify the engine torque transferred to the wheels when higher accelerations are needed. For such reasons, every type of transmissions has some devices that allow to select the ratio between its input shaft angular speed (engine side) and its output shaft angular speed (the side toward the wheels). The transmission's input shaft is connected to the flywheel of the engine, while the output shaft of the transmission is connected to the final drive (that contains the differentials) through the drive shaft.

Even though such subsystems are differently located depending on the vehicle layout (if front-wheel or rear-wheel driven or even all-wheel driven), they all are parts of the powertrain and determine its behavior.Transmissions can be viewed also as systems that allow to transfer power from the engine to the vehicle in a smooth and efficient way. In order to achieve such basic and fundament...
