Data communication method between the virtual machines of a vehicle electronics unit and their network interface to a local vehicle network of a vehicle

摘要

The invention relates to a data communication method between the virtual machines (P1, P2) and the network interface of a vehicle electronics unit (10), the vehicle electronics unit (10) comprising: the at least two virtual machines (P1, P2) each having a virtual network interface (5.1, 5.2), a memory (3) each having a virtual machine (P1, P2) exclusively associated memory sections (3.1, 3.2), each memory section (3.1, 3.2) direct memory areas (3.10, 3.20) for the direct communication of the virtual machine (P1, P2) with its associated virtual network interface (5.1, 5.2), and - The physical network interface (2.1) for establishing a communication connection between each of a virtual network interface (5.1, 5.2) of a virtual machine (P1, P2) and a vehicle network (B1).
