Method for operating an internet-protocol-based functional system and associated internet-protocol-based functional system in a vehicle

摘要

A method for operating an Internet-Protocol-based functional system in a vehicle with at least two system units separatably connected to one another in which a local IP address is respectively allocated to a first system unit and to a second system unit and data are transmitted between the first system unit and the second system unit with a reproduction rule for the purpose of carrying out a first function, wherein one of the system units acts as a transmitting system unit and the other system unit acts as a receiving system unit. The data are evaluated in the receiving system unit with the reproduction rule, the reproduction rule is used to refer to a memory location of a memory associated with the execution program code for the first function, and the first function is carried out via the receiving system unit using the data in the reproduction rule.

1. A method for operating an Internet-protocol-(IP-)based functional system in a vehicle with at least two system units which are separably connected to one another, the method comprising a first system unit of the at least two system units:
respectively allocating a local IP address to each of the first system unit and a second system unit of the at least two system units to enable Internet-capable communication between the first system unit and the second system unit, transmitting data comprising a reproduction rule for carrying out a first function between the first system unit and the second system unit via an IP protocol stack, wherein the first system unit acts as a transmitting system unit and the second system unit acts as a receiving system unit, acting as a receiving system unit evaluating the data in the receiving system unit using the reproduction rule, using the reproduction rule to refer to a memory location of a memory associated with an execution program code to perform the first function at the receiving system unit, performing the first function by the receiving system unit using reference information in the reproduction rule, and specifying the reproduction rule for carrying out the first function in accordance with a standardized format, wherein the standardized format is specified such that a range of functions which is transferred using the reference information in the reproduction rule can run without previous system integration.
