  • Ground vehicles can navigate using signals from external navigation systems such as the Global Positioning System (GPS) (Figure 1.1), or by using signals from internal devices such as a compass, an odometer, a gyroscope, an accelerometer, or a full-blown inertial navigation system (INS). In practice, the most reliable and accurate navigation is obtained by combining data from all available sources, including static databases such as a digitized map. This chapter will discuss many of these sources of navigation data, and methods for combining them....

  • Lead-acid starter batteries are used in land, sea, and air vehicles. Batteries for vehicles are discussed in this chapter. The production of starter batteries approaches 60 million pieces. About 16 million pieces are used for motor vehicle production and about 38 million pieces keep the vehicles ready for operation as back-up batteries. A considerable number of imported and exported pieces play a part in this market. With these numbers Europe achieves about two-thirds of the U.S. production. ...

  • The applications of underwater vehicles have shown a dramatic increase in recent years, such as, mines clearing operation, feature tracking, cable or pipeline tracking and deep ocean exploration. According to different applications, the mechanical and electrical configuration and shape of an underwater vehicle are different. For instance, manipulators are necessary when doing mines clearing operation or some other tasks which need to deal with environment.

  • The demand of vehicle navigation and guidance has been urgent for many years. The idea of integrating multisensor navigation systems was implemented. The most efficient multisensor configuration is the system integrating an inertial navigation system (INS) consisting of MEMS based micro sensors and a global positioning system (GPS). In such system, the GPS is used for providing position and velocity whereas the INS for providing orientation. The estimation of the system errors is performed by a Kalman...

  • BMW first introduced Park Distance Control (PDC) on the 7 series (E32) in 1992. PDC is a driver assistance system that facilitates parking and manoeuvring in confined spaces. The rear area of the vehicle is monitored by four ultrasonic transducers that are integrated into the rear bumper. On some vehicles, the front area of the vehicle is also monitored by four additional ultrasonic transducers in the front bumper. Ultrasonics is the term used to describe sound above the human hearing range at frequencies between 20 kHz and 1000 MHz.

  • In-vehicle dialogue systems often contain more than one application, e.g. a navigation and a telephone application. This means that the user might, for example, interrupt the interaction with the telephone application to ask for directions from the navigation application, and then resume the dialogue with the telephone application. In this paper we present an analysis of interruption and resumption behaviour in human-human in-vehicle dialogues and also propose some implications for resumption strategies in an in-vehicle dialogue system. determine type of workload and act accordingly. ...

  • Discussion Questions & Answers: Cf: F & O (2005) and F, O, & F (2002) Q1. Why should a tax on gasoline provide a larger incentive to reduce air emissions from motor vehicles than an annual tax on owning a vehicle? Answer: The answer depends upon the magnitude of the fuel tax relative to the vehicle tax. A fuel tax targets the three components of emission reduction (i.e. a) number of vehicles on the road; b) miles per vehicle; and c) emissions per mile). On the other hand, an annual tax affects only the marginal decisions to put a car...

  • Hydrogen fuel cells are one of the most promising alternatives to internal combustion engine hybrids and pure battery electric power for propelling passenger vehicles. Compared to internal combustion engine hybrid vehicles burning hydrocarbon fuels, fuel cell vehicles offer three primary advantages. First, the fuel cell system produces no tank-to-wheel carbon dioxide emissions and no other harmful emissions such as oxides of nitrogen, carbon monoxide, or particulates. Second, the fuel cell system offers the potential for approximately 30% higher well-to-wheel energy efficiency.

  • The idea of combining electrical engines and internal combustion (IC) engines has a long history. In 1901 J. Lohner and F. Porsche had already presented a first hybrid electric vehicle (HEV). But this revolutionary concept did not reach full maturity because the electrical components were not developed. The main concern was the battery, a high-performing battery system with acceptable long-term endurance was not available at the time. The battery of the vehicle shown in Figure 1 had a weight of not less than 1800 kg. It was not until the end of the twentieth century that HEVs became a...
