The problems of global warming, a decrease of the available natural resources and many other problems in the world that happen recently become the major cause for increasing the demand for a new type of vehicle. That vehicle can be an environmental friend and so that a new generation of vehicles has been invented and tried to solve and avoid many problems. In this chapter, the proposed system is called the Multi-Converter/Multi-Machine system (MCMMS) which consists of two Synchronous Reluctance Motor (SynRM) that drive the two rear wheels of Pure Electric Vehicle (PEV). The SynRM speed and torque are controlled by using three different strategies of the PID controller. The PSO algorithm has been used as an optimization technique to find the optimal PID parameter to enhance the drive system performance of the PEV. In this system, the space vector pulse width modulation inverter for voltage source (VS-SVPWMI) has been employed to convert the DC battery voltage to three-phase AC voltage that feeds the SynRM motor in the PEV. The linear speed of the vehicle is controlled by an Electronic Differential Controller (EDC) which gives the reference speed for each driving wheel which depends on the driver reference speed and the steering angle. The specified driving route topology with three different road cases has been applied to acting and show the resistive forces that affected on the PEV during its moving on the road. In addition, to test the efficiency and stability of the PEV on the roads. Hence, this chapter has a full design, simulation and several comparison results for the propulsion electric vehicle system and it has tested implemented in the Matlab/Simulink environment version R2020a.

Recently, scientists in South Korea developed on-line electric vehicle (OLEV), which is a kind of electric vehicle that can be charged wirelessly while it is moving on the road. The battery in the vehicle can absorb electric energy from the power transmitters buried under the road without any contact with them. Several billing schemes have been presented to offer privacy-preserving billing for OLEV owners. However, they did not consider the existence of free-riders. When some vehicles are being charged after showing the tokens, vehicles that are running ahead or behind can switch on their systems and drive closely for a free charging. We describe a billing scheme against free-riders by using several cryptographic tools. Each vehicle should authenticate with a compensation-prepaid token before it can drive on the wireless-charging-enabled road. The service provider can obtain compensation if it can prove that certain vehicle is a free-rider. Our scheme is privacy-preserving so the charging will not disclose the locations and routine routes of each vehicle. In fact, our scheme is a fast authentication scheme that anonymously authenticates each user on accessing a sequence of services. Thus, it can be applied to sequential data delivering services in future 5G systems.

This paper contains a proposed controller based on optimal recurrent wavelet neural network (RWNN) with PID controller to control the velocity and hence the stator current as well as the developed thrust of three phase linear induction motor (LIM) which consider the end effects. A vector control represented by indirect field oriented control (IFOC) technique is appointed to attain velocity and flux control for different loading conditions. Moreover, a voltage source inverter based on space vector pulse width modulation (SVPWM) is utilized to give the required stator voltage of LIM. A well-known particle swarm optimization (PSO) algorithm is employed for online tuning of the proposed controller. The computer simulation results show that this controller is effective and gives preferable and rigorous performance compared with a results obtained from conventional wavelet neural network (WNN) and PID controllers.

This chapter investigates the discourse surrounding hitchhiking in the post-World War II era to understand the ways in which rising prosperity, exponential growth in car ownership, and the Cold War political atmosphere affected American notions of community, masculine individualism, and personal safety. Many motorists greeted hitchhikers on the road with increased suspicion. Likewise, media and law-enforcement officials began to predominantly frame the practice in terms of risk and danger. Regardless, this did little to dampen the spirits of a new generation of middle-class white youths who began to associate hitchhiking with thrifty adventure and a ticket to authentic experience on the nation’s expanding interstate highway system. At the same time, African Americans began to aggressively push for equal rights and the end of segregation. Notably, automobility, bus boycotts, and hitchhiking were a key front in this struggle.

The chapter questions a conventional line of interpretation of the political relevance of the Internet in democratic countries: if on the one hand new communication media such as the Internet represent a positive element in the fight against the hubris of power; on the other hand, the same technologies can serve the agenda of those who want to influence popular consent in support of questionable politics and, hence, hinder the representative system in its very essence. To elucidate this point, the chapter focuses on the Road Tax online-petition that in the early months of 2007 attracted almost 2 million signatures on the UK Government e-Petition website. My argument here is that when simple and historical democratic means such as petitions are coupled with the new generation of Web technologies, the outcome might be unexpected. The road-tax petition will serve us as a blueprint of: the possibilities embedded in the use of new technologies within representative democratic systems, the challenges they pose for democracy, and their unforeseen consequences.

The Relationship

This chapter deals with the problem of energy storage inside an electric vehicle. The main source of energy is based on a wireless system. This recharge tool regroups inside several components as the storage system, which consists of an ensemble of batteries and serving as the main power source, a special electronic converter that is based on the buck-boost principle and a coil receiver placed undo the vehicle. From the other side, one or more than coil transmitters are placed on the road, where the vehicle is. Modeling all of these components and expressing their mathematical models seems interesting for defining the possible control method that can guarantee a high autonomy when the vehicle is moving. So, taking into account if the care is driving or stopped, this recharge system is studied for verifying the effectiveness of this recharge system and showing the relationship between the vehicle situation and the quantity of received power. Using the platform Matlab/Simulink the results were shown and discussed.
