Terms & Definitions
| Term | Definition |
|---|---|
| Business Use-Case | Is a specific form of use-case, where the actor is a group of people, one or multiple departments of a company or one or many companies. It typically describes a business process. Business use-cases can be broken down into user use-cases. Example: ECU calibration and measurement. |
| Calibration | The process of ECU parameter tuning. Tests with ECU hardware and software in the loop are carried out. ECU internal variables and external sensor data is recorded and analyzed. The values of internal ECU parameters are determined as a result of this process. |
| Certification | The process of confirmation that a system complies to a specific standard or a specified subset of a standard. |
| Curve | 1D-table with two axes. |
| Database | Is an organized collection of data. |
| Diagnostic Tester | Is a device that can be connected to the diagnostic port of a vehicle and can read, write and modify diagnostic data in ECUs. |
| Diagnostics | The subsystem of an ECU or ECU networks, which performs error detection, handling and communication. |
| End-of-Line | Denotes the final stages of the assembly line in vehicle production. |
| File Format | Is a description about how information is encoded and structured and given a specific syntax for storage in a computer file. |
| Homologation | The process of certifying compliance of a product with regulatory requirements, e.g. that it meets public safety and environment standards. |
| Label | Denotes the name of ECU data, as it is stored by and displayed in MCD-tools. |
| Map | 2D-table with three axes. |
| Measurement | The process of recording data from internal ECU memory and external sensors. |
| Memory Page | An area in memory, characterized by a start and end address. |
| Metadata | Is data which provides information about other data. |
| Metalanguage | Is language for describing other languages on a higher abstraction level. |
| Port | Synonymous expression for 'Interface'. |
| Public Release Candidate | ASAM published a Public Release Candidate for the first time for ASAM OpenSCENARIO V2.0.0. A public release candidate enables the industry to test and implement a standard before its final release. The feedback helps ASAM to make sure that the full release is as good as possible. |
| Public Specification | A specification which is publicly available. |
| Real-Time | Property of a subsystem, which is subject to timing constraints in such a way that it must be capable to respond to events from its environment timely enough so that the overall system remains stable and performs as specified. |
| Scalar | A real number. |
| Schema | A formal definition of the structure and syntax of text files. |
| Simulation | Is the process of imitation of the behavior of a modeled real-world system over time. |
| Specification | A document, which describes in detail the interfaces and behavior of a technical system for the purpose of implementing, integrating and operating the system. |
| Standard | A public specification, which has been developed by experts in a defined consensus-driven development process and was released by officials that represent a significant share of the industry for which it is targeted, giving the specification the necessary legitimacy to be called a 'Standard'. |
| Stimulation | The process to input data into a test system during test execution. |
| Stimuli Data | Is input data for tests. |
| Technical Use-Case | Is a specific form of use-case, where the actor is a system or system component. It typically describes a technical process that is needed to support a user use-case. Example: XCP protocol commands for DAQ start. |
| Tuple | Is a finite ordered list of elements. |
| Use-Case | Describes how an actor interacts with a system to achieve a goal by carrying out specific steps of actions or events. The actor can be a human or another system. ASAM's use of the term 'use-case' is based upon the definition in UML. |
| User Use-Case | Is a specific form of use-case, where the actor is one person. Is often synonymously used with the term 'use-case'. User use-cases can be broken down into technical use-cases. Example: Measurement of ECU data. |
| Validation | The process of determining that a system performs and meets the needs for identified end users. |
| Variant | One of multiple, interchangeable sets of data or functions in an ECU. |
| Workshop Tester | Same as 'Diagnostic Tester'. |
