The use of standards in the Automotive sector generates significant efficiency gains. Tests can start earlier due to the unambiguousness of data descriptions, ECUs become less expensive due to standardized buses and protocols and the use of uniform runtime environments saves rework and maintenance costs.
To ensure that our customers benefit directly from the results of standardization, we are an active member of the key standardization bodies in automotive electronics, such as SAE, ASAM and ISO.
The growing complexity in automotive electronics requires manufacturer-independent standards. Standardized data descriptions become important at the latest when several participants in several companies exchange information and a multitude of applications are based on the same information. The standards defined here are also useful for processing information in different ways – in a structured form.
Standardized Application Programming Interfaces (API) are used to exchange information between an application and individual program parts in a standardized way. An API is a program part that is made available by a software system to other programs for connection to the system. The transfer of data and commands is structured in compliance with a previously defined syntax. Along with access to databases or hardware (hard disk, graphics card), the creation of components of the graphical user interface is enabled or simplified.
Bus systems describe specialized internal communication networks that connect components in automobiles, buses, trains, aircraft, and industrial or agricultural vehicles. Vehicle control requirements (e.g. ensuring message delivery, conflict-free messages, minimum delivery time, etc.) require the use of less common network protocols (see Protocols).
Standardized protocols are necessary to meet the special requirements of the complex networking of electronic components in commercial vehicles. The standards defined here for the use of bus systems were created by the American Society of Automotive Engineers (SAE) in close cooperation with OEMs and suppliers.
