Device and method for controlling a technical system

A device for controlling a technical system of a motor vehicle, the device configured to perform a method, the method comprising:

• resetting at least one hardware component of the device, wherein a) the device includes a plurality of cores and the resetting includes a resetting of a single core of the plurality of cores, such that the resetting of the single core does not influence one or more further cores of the plurality of cores, and/or b) a resetting of modules of the device and/or of any existing external circuits is carried out such that several independent applications can be operated and the several independent applications do not influence one another;
• wherein the device includes at least one of the following features (i)-(ii):
• (i) the method is used for at least one of the following:
• (a) enabling a deterministic runtime behavior of at least some applications of the device;
• and
• (b) avoiding a new homologation for one application when changing at least one further application;
• and
• (ii) the method further comprises at least one of the following steps:
• (a) forwarding information characterizing an operating state with regard to a functional safety of an application to at least one further unit, the at least one further unit being a unit arranged externally to the device;
• (b) at least temporarily separating partitions or applications from one another using a quality of service and/or at least one parameter characterizing the quality of service, wherein at least one application sets the quality of service, the quality of service being characterizable by latency and/or bandwidth for at least one peripheral component;
• (c) securing a deterministic data exchange between a plurality of applications running on a computer or the device using a memory region assignment implemented using at least one memory protection unit;
• and
• (d) placing orders by a plurality of partitions or applications which cannot be overwritten or influenced respectively by other partitions or applications using a mechanism implemented in at least one hardware module or peripheral component.

A non-transitory computer-readable storage medium on which are stored instructions for controlling a technical system of a motor vehicle, the instructions, when executed by a computer, causing the computer to perform a method, the method comprising the following steps:

• resetting at least one hardware component of a device, wherein a) the device includes a plurality of cores and the resetting includes a resetting of a single core of the plurality of cores, such that the resetting of the single core does not influence one or more further cores of the plurality of cores, and/or b) a resetting of modules of the device and/or of any existing external circuits is carried out such that several independent applications can be operated and the several independent applications do not influence one another;
• wherein the non-transitory computer-readable storage medium includes at least one of the following features (i)-(ii):
• (i) the method is used for at least one of the following:
• (a) enabling a deterministic runtime behavior of at least some applications of the device;
• and
• (b) avoiding a new homologation for one application when changing at least one further application;
• and
• (ii) the method further comprises at least one of the following steps:
• (a) forwarding information characterizing an operating state with regard to a functional safety of an application to at least one further unit, the at least one further unit being a unit arranged externally to the device;
• (b) at least temporarily separating partitions or applications from one another using a quality of service and/or at least one parameter characterizing the quality of service, wherein at least one application sets the quality of service, the quality of service being characterizable by latency and/or bandwidth for at least one peripheral component;
• (c) securing a deterministic data exchange between a plurality of applications running on a computer or the device using a memory region assignment implemented using at least one memory protection unit;
• and
• (d) placing orders by a plurality of partitions or applications which cannot be overwritten or influenced respectively by other partitions or applications using a mechanism implemented in at least one hardware module or peripheral component.
