VDA 340 (08/2020)

In a modern vehicle, essential vehicle systems are no longer independent of one another, but work in a functional network. This means that the sub-systems cannot be developed and validated separately, but must be coordinated and tested in each specific constellation, which entails high development efforts and risks. These problems already arise to a large extent in vehicle longitudinal control today, i.e. the vehicle systems that can be used to accelerate, decelerate or stop the vehicle. These include in particular the various propulsion systems, transmissions, brakes, generators and the corresponding interfaces to the driver assistance systems.
To solve this problem, this recommendation considers a framework and corresponding interfaces for vehicle longitudinal control, which are derived from the design of a modular architecture. This makes it possible to freely combine any subsystems with the least possible additional effort. The approach is based on the proven principles of object-oriented design. The aim of this recommendation is to introduce
the basic object-oriented principles and their application to the abstract design of the framework and interfaces of a modular vehicle longitudinal control architecture.
