Method for operating an internet-protocol-based functional system and associated internet-protocol-based functional system in a vehicle
First Claim
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, andspecifying 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.

Abstract
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.

10. An Internet-protocol-(IP-)based functional system in a vehicle, the system comprising:
-
a first system unit of at least two system units and a second system unit of the at least two system units which are connected separably to one another; and a network configuration server to assign a local IP address to each of the first system unit and to the second system unit, wherein data comprising a reproduction rule for carrying out a first function can be transmitted between the first system unit and the second system unit via an IP protocol stack, wherein the first system units acts as a transmitting system unit and the second system unit acts as a receiving system unit, wherein the data is evaluated in the receiving system unit with the reproduction rule to refer to a memory location of a memory which is allocated to the execution program code of the first function to carry out the first function via the receiving system unit, wherein the reproduction rule for carrying out the first function is specified in accordance with a standardized format, and 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. - View Dependent Claims (11)
