Für den Funktionsverbund zwischen aktiven Bremssystemen und anderen aktiven Fahrwerk- und Antriebsystemen mit dem Ziel der Fahrdynamikregelung bilden sich zwei Vorzugsarchitekturen heraus. Die Auswahl orientiert sich vor allem an nicht-funktionalen Kriterien. Aus der Funktionsstruktur ergeben sich Anforderungen für die Schnittstellen zwischen einem Fahrdynamik-Verbundregler und den Aktorsystemen.

    Increasingly, vehicle dynamics is controlled by more than one active system. Beyond ESP, steering, vertical dynamics and drive-train actuators are installed in new vehicles. The functional domains of the different actuators are generally not separated; e.g. active braking and active steering both contribute to stabilizing. The functional overlap requires a certain degree of coordination between the systems in order to avoid interferences and furthermore to generate synergies beyond the sum of the single system benefits. The term Vehicle Dynamics Management (VDM) denotes a set of algorithms and electronic systems, which are set up for coordinated vehicle dynamics control using more than one actuator with some functional overlap. The architecture task associated with VDM basically consists of finding an overall system structure that supports the implementation of the above mentioned functional aims, and meets additional non-functional criteria. For the vehicle functions, two VDM function structure models are currently evolving in the industry: a) Integrated function structure; b) Cooperative function structure. The integrated function structure offers advantages mainly with respect to engineering effort and electronics resources. On the other hand, it offers considerable potential for differentiation by OEM designed vehicle functions. Therefore it is expected that the majority of VDM projects will turn to this function structure. For vehicle platforms with a wide variety of actuator configurations and unique proprietary functions a cooperative VDM structure may have strategic advantages. On the basis of non-functional considerations, mainly cost advantages, the majority of VDM projects is expected to employ an integrated function structure. As it is open for OEM designed functions, it offers a differentiation potential which will meet most demands.
