Method for operating at least two data processing units with high availability, in particular in a vehicle, and device for operating a machine
First Claim
1. A method for operating at least two data processing units with high availability, in a vehicle,in which, a first data processing unit and a second data processing unit can each provide the same function to an extent of at least 60% or at least 90%,in which, the second data processing unit removes automatically at least one entry for a process to be executed from a memory unit of the second processing data unit to selectively reduce a redundant processing of a function of the vehicle, wherein an entry for a process to be executed from a memory unit of the first data processing unit to perform the function of the vehicle is still present on the first data processing unit,wherein the removal of the at least one entry occurs based on a detection of an operating state of the vehicle for an operation of which the first data processing unit and the second data processing unit are used;
- wherein;
in a traveling operating state of the vehicle, the first data processing unit is switched on, the second data processing unit is switched on, a first steering control unit is switched on, and a second steering control unit is switched on,in a stopped operating state of the vehicle, the first data processing unit is switched on, the second data processing unit is switched off, the first steering control unit is switched on, and the second steering control unit is switched off.

Abstract
A method for operating at least two data processing units with high availability, in particular in a vehicle, is provided. A first data processing unit and a second data processing unit can each provide the same function to an extent of at least 60 percent or at least 90 percent. The second data processing unit removes automatically at least one entry for a process to be executed from a memory unit or automatically places itself into a standby mode.

13. A device for operating a vehicle comprising:
-
a first data processing unit; and a second data processing unit, wherein the first data processing unit and the second data processing unit provide the same functions to an extent of at least 60 percent or to an extent of at least 90 percent; and a control unit in the second data processing unit, wherein the control unit removes at least one entry for a process to be executed from a memory unit of the second processing data unit to selectively reduce a redundant processing of a function of the vehicle, wherein an entry for a process to be executed from a memory unit of the first data processing unit to perform the function of the vehicle is still present on the first data processing unit; and wherein the first data processing unit is higher-ranking than the second data processing unit with respect to providing functions or with respect to the redundancy, as entered in the memory unit of the first data processing unit; wherein the removal of the at least one entry occurs based on a detection of an operating state of the vehicle for an operation of which the first data processing unit and the second data processing unit are used; wherein; in a traveling operating state of the vehicle, the first data processing unit is switched on, the second data processing unit is switched on, a first steering control unit is switched on, and a second steering control unit is switched on, in a stopped operating state of the vehicle, the first data processing unit is switched on, the second data processing unit is switched off, the first steering control unit is switched on, and the second steering control unit is switched off. - View Dependent Claims (14, 15)
