8. Carsharing

This chapter discusses carsharing. Section 8.1 introduces the carsharing concept and the different variants of it as well as carsharing services offered so far. The focus in Sect. 8.2 is on the carsharing concept by Daimler, its Car2Go business model. In Sect. 8.3 the use cases in regard to the different phases of carsharing are analyzed, and the resulting requirements are discussed. Section 8.4 describes significant modifications to the hardware and software infrastructure of a smart car for using it in the carsharing business model. The focus of Sect. 8.4 is on connectivity which is realized through a GSM module that is embedded in the telematics unit. In Sect. 8.5 the impact of electric vehicles in carsharing applications is discussed. It also shows the block diagram of a standard electric vehicle. Section 8.6 refers to the carsharing activities by other OEMs and their brands. Since the whole use case of carsharing relies on the constant connectivity between the car and the backend system, the proper security of the used vehicles is a major concern which can be realized by intrusion detection and prevention to avert vulnerabilities through cyberattacks. In this regard Sect. 8.7 introduces cyberattack surfaces and discusses the mitigation of cyberattacks (see also Chap. 6). Section 8.8 finally wraps up within a conclusion, while Sect. 8.9 contains a comprehensive set of questions on the carsharing business model, and finally followed by references and suggestions for further reading.
