Method for configuring a control unit, control unit and vehicle
First Claim
1. A method for configuring a control unit in a vehicle, comprising:
- transmitting a vehicle-type-specific function cluster assignment for the vehicle from a data source to the control unit, the function cluster assignment allocating the control unit to a vehicle-type-specific selection of function clusters,the function cluster assignment allocating one of the different subsets of function clusters that can be allocated to the control unit, such that with the subset of function clusters allocated to the control unit, the control unit is assigned to perform functions for one function cluster or to simultaneously perform functions for a plurality of function clusters;
receiving the function cluster assignment by the control unit;
preparing the control unit for use of the function cluster assignment;
validating the function cluster assignment in the control unit; and
controlling the allocated function cluster assignment subset.

Abstract
In order to configure a control unit for a vehicle, a method is provided which involves: transmission of a functional cluster assignment by a data source to the control unit, the functional cluster assignment assigning the control unit to a selection of functional clusters; reception of the functional cluster assignment by the control unit; preparation of the control unit for the use of the functional cluster assignment; activating the validity of the functional cluster assignment in the control unit, and use of the functional cluster assignment in the control unit. The functional cluster assignment is transmitted via a data network, preferably formed using a CAN bus, LIN bus, MOST bus or FlexRay bus system. The downloading of the functional cluster assignment to the control unit makes software releases that are specific to vehicle type and the time spent on their associated program maintenance superfluous.

18. A control unit in a vehicle, the control unit comprising a control processor to:
-
receive a vehicle-type-specific function cluster assignment from a data source, to allocate the control unit to a vehicle-type-specific selection of function clusters, the vehicle-type-specific function cluster assignment being specific to the vehicle type of the vehicle in which the control unit is installed, the function cluster assignment being one of the different subsets of function clusters that can be allocated to the control unit, such that with the subset of function clusters allocated to the control unit, the control unit is assigned to perform functions for one function cluster or to simultaneously perform functions for a plurality of function clusters; prepare the control unit for use of the function cluster assignment; validate the function cluster assignment in the control unit; and control the function cluster assignment subset.

19. A vehicle comprising at least one control unit, each control unit comprising a control processor to:
-
receive a vehicle-type-specific function cluster assignment from a data source, to allocate the control unit to a vehicle-type-specific selection of function clusters, the vehicle-type-specific function cluster assignment being specific to the vehicle type of the vehicle in which the control unit is installed, the function cluster assignment being one of the different subsets of function clusters that can be allocated to the control unit, such that with the subset of function clusters allocated to the control unit, the control unit is assigned to perform functions for one function cluster or to simultaneously perform functions for a plurality of function clusters; prepare the control unit for use of the function cluster assignment; validate the function cluster assignment in the control unit; and control the function cluster assignment subset.
