GB/T 41901.2 Road Vehicles - Extended Vehicle (ExVe) Methodology - Part 2: Methodology for Designing the Extended Vehicle (GB/T 41901.2-2022, ISO 20077-2:2018, MOD) 3 Terms and Definitions What is defined in GB/T 41901.2, and the following terms and definitions are applicable to this document. 3.1 Extended Vehicle Extended vehicle refers to a vehicle system that satisfies the specification requirements of the vehicle manufacturer, but exceeds the physical scope of road vehicle, and is composed of road vehicle, external interfaces, extended accessories and data communications generated through the external interfaces. NOTE 1: extended vehicles can be without extended accessories. NOTE 2: when the communication object is a non-extended accessory (for example, road infrastructure or other traffic participants), the extended vehicle is composed of road vehicle, external interfaces and data communications generated through the external interfaces, and the road infrastructure and other traffic participants do not belong to the extended vehicle. NOTE 3: see Appendix B for common application fields of extended vehicle; see Appendix C for the methodological standards for extended vehicle. 3.2 Off-board System Off-board system refers to off-vehicle software and hardware used to realize the required functions for road vehicles through defining, designing, developing and / or manufacturing. 3.3 Extended Accessory Extended accessory refers to an off-board system provided by the extended vehicle manufacturer and used to realize the extended function. 3.4 Manufacturer Manufacturer refers to a manufacturer or corporation that issues the motor vehicle exit-factory certificate or product consistency certificate, and undertakes the responsibility for vehicle product and the uniqueness of the vehicle identification number (VIN), and is irrelevant to the location of the assembly plant. 3.5 ExVe Manufacturer ExVe manufacturer refers to the manufacturer that manufactures extended vehicles. 3.6 Functional Requirement Functional requirement refers to a description provided by the vehicle manufacturer to ensure necessary actions and / or results. NOTE: functional requirement is provided by the institution responsible for product or process design. 3.7 Function Function refers to a task, behavior or activity performed to satisfy a functional requirement. EXAMPLE: turn on-off the engine. NOTE: the same function can be used for many different use cases. 3.8 Use Case Use case refers to a sequence of interactions between one or multiple participants and a related system. This sequence of interactions has specific objectives and quantifiable results. EXAMPLE: read all active DTCs. NOTE 1: “read all active DTCs” can consist of the following interactions: communication initialization, vehicle identification, sending a request to obtain DTC information, receiving DTC information and communication termination. NOTE 2: the operator can be human or machines. NOTE 3: in order to implement the design of extended vehicles, use case needs to be determined by appropriate scenarios and functional requirements. 3.9 Use Case Cluster Use case cluster refers to a set of use cases with the same objective and quantifiable result. EXAMPLE: remote diagnostics and fleet management. NOTE 1: use case cluster can itself be re-divided into different domains, in which, different types of technical solutions may arise, and some solutions are applicable to multiple domains. NOTE 2: extended vehicles can be used in all vehicle-connected use case cluster domains, such as: cooperative ITS, fleet management, remote diagnostics and vehicle sharing, etc. 3.10 Web Service Web service refers to a software system for equipment interaction over the network with an interface in a machine-processable format. 4 Abbreviations ExVe: Extended Vehicle FMS: Fleet Management System ITS: Intelligent Transportation System RSI: Roadside Inspection V2I: Vehicle-to-Infrastructure V2V: Vehicle-to-Vehicle 5 General Information of Extended Vehicle 5.1 Concept of Extended Vehicle 5.1.1 Extended vehicle refers to all technical components that can realize vehicle functions, and external interfaces are also included, as it is shown in Figure 1 and Figure 2. Figure 1 represents the overall concept; Figure 2 represents representative interfaces, including: ---physical connection interface; ---web service interface; ---wireless real-time communication interface; ---other interfaces: there is no standardization requirement for such interfaces. Appendix B (informative) Intended Application Fields of Extended Vehicle B.1 Extended vehicle is not a special technical solution created to solve specific requests (for example, remote diagnosis). This technology, which extends conventional road vehicles to include off-board systems, can be applied to all fields, in which, vehicle connectivity is needed. B.2 There are six main intended application fields (see Figure B.1) for extended vehicles. ---Vehicle maintenance and upgrade field. The typical use case cluster of this field is remote diagnostics, prognostics, repairs and online software upgrades. This field is characterized by a strong influence of national or local regulations. ---Vehicle inspection field. The typical use case cluster of this field is remote RSI, which is characterized by inspection operators regulated by local managing institutions. ---Driving task support field. The typical use case cluster of this field includes V2V, V2I and communication supporting driving assistance and automatic driving, etc. This field is characterized by the request for low-latency communication. ---Transportation management field. The typical use case cluster of this field is remote FMS, which is characterized by the fleet as a whole. ---Manufacturing and sales field. The typical use case cluster of this field is remote diagnostics of vehicles during the manufacturing process, which is characterized by the fact that the vehicle owner is still the vehicle manufacturer. ---Non-vehicle field. The typical use case cluster of this field is infotainment, vehicle insurance, remote driver and driving survey, which is characterized by a wide variety of use cases, often originating outside the vehicle industry. B.3 In the face of so many requests, a good description of the use case cluster is crucial for developing technical solutions based on extended vehicles. Appendix C (informative) Methodological Standards of Extended Vehicle C.1 Content of GB/T 41901 Series Documents GB/T 41901 series documents include various general specifications applicable to extended vehicles. These documents do not include any specific technical specifications. ---This document is Part 1 of GB/T 41901, which includes the basic definitions, concepts, examples and related standards on extended vehicles. ---GB/T 41901.2 is used to guide the design and development of extended vehicles. C.2.2 introduces its content. C.2 GB/T 41901.2 C.2.1 Purpose of GB/T 41901.2 The purpose of GB/T 41901.2 is to guide the design (physics, documentation and support, etc.) of extended vehicle and its external interfaces, so as to restrict the risks associated with safety, protection and regulatory compliance, especially when fair competition is involved. The majority of vehicle manufacturers have implemented an effective quality management system (for example, the certified compliance with ISO 9001 or equivalent series of standards). Therefore, the design quality of extended vehicle can be ensured through the following steps: ---Based on the rules and basic principles in GB/T 41901.2, the vehicle manufacturer establishes its own method and process to design extended vehicle, so as to satisfy the legal requirements of the target sales market; ---The vehicle manufacturer adopts the method and process mandated by its quality management system. GB/T 41901.2 aims to guide the design process of extended vehicles and does not involve the process of obtaining information from the manufacturer of extended vehicle to develop new services. However, in order to reduce risks, it is recommended that all parties choosing to apply GB/T 41901.2 may adopt these processes. C.2.2 Content of GB/T 41901.2 GB/T 41901.2 specifies a set of common rules and basic principles, and each vehicle manufacturer can derive its own method or process to design extended vehicles in accordance with the rules and basic principles. ......
