V2XMiddleware: Publish-Subscribe-Datenverteilung für vernetzte Flotten

V2XMiddleware setzt strikte QoS-Richtlinien wie Deadlines und Langlebigkeit durch, damit Trajektorienplaner stets frische Sensordaten verzögerungsfrei erhalten.

Entkopplung von Low-Level-HF-Signalen von der High-Level-Planung autonomer Systeme

Autonome Pfadplaner sollten keine rohen ASN.1-Funkbitströme parsen müssen. V2XMiddleware wandelt eingehende CAM-, DENM- und CPM-Pakete in stark typisierte interne Topics um, die über das Ethernet-Backbone des Fahrzeugs verteilt werden.

Core Engineering Areas

• OMG DDS QoS Profiles — Configuring best-effort versus reliable topic delivery over lossy vehicular communication backbones.
• SOME/IP SOA Integration — Publishing V2X hazard alerts as standardized AUTOSAR services consumable by infotainment and ADAS.
• Zero-Copy Serialization — Direct in-place memory access to incoming vehicle telemetry without memory allocations.
