Abstract: A control unit including at least one processor and at least one memory connected to the at least one processor, a virtualization system, the virtualization system including a scheduler for scheduling a plurality of virtual machines to assign processing time to each of the virtual machines according to a predetermined fixed sequence of virtual machine switches forming a cycle period, which is repeated, the cycle period being the minimum time period after which the scheduling is repeated, wherein the virtualization system and the plurality of virtual machines are real-time systems, the virtual machines having respectively at least one real-time attribute, wherein at least one the real time attribute of a first virtual machine are different to the corresponding real-time attribute(s) of a second virtual machine, wherein predetermined fixed sequence of virtual machine switches is calculated based on the at least one real time attribute.

Abstract: A method including running a virtualization layer on a processor, the virtualization layer being adapted to assign processor time and memory to first and second guest operating systems running on the virtualization layer, wherein the first guest operating system is a real time operating system, obtaining, by the second guest system, information to be displayed on a display, preparing, by the second guest system, a display frame to be sent to the display, reading, by the first guest system, a portion of the display frame, or retrieving, by the first guest system, information about a read portion of the display frame, and determining, by the first guest system, whether the information sent to the second guest system is correctly generated in the display frame.

Abstract: A method for scheduling guest systems and/or threads in a virtualization system that assigns processor time and memory space to guest systems and including a virtualization system scheduler, the method including running a first guest system that includes at least one first thread and at least one second thread running in the first guest system, and a guest system scheduler that assigns processing time to the at least one second thread, assigning a plurality of time reservations to the first guest system, wherein the plurality of time reservations include a first time reservation associated to one first thread and a second time reservation associated to the guest system scheduler of the first guest system, assigning processor time to the first guest system according to the second time reservation, and assigning processor time to the at least one first thread of the first guest system according to the first time reservation.

Abstract: A system including a processor with a plurality of cores having the same instruction set architecture, at least one memory connected to the processor, a plurality of virtualization systems adapted to run respectively on one core, the plurality of virtualization systems including a first virtualization system adapted to run on a first core and a second virtualization system adapted to run on a second core, wherein the first virtualization system has a first characteristic with a first parameter and the second virtualization system has a second characteristic with a second parameter, wherein the parameter of the first characteristic and the parameter of the second characteristic are incompatible when implemented in a single virtualization system; and communication module for enabling the plurality of virtualization systems to communicate with each other.

Abstract: A method for scheduling guest systems and/or threads in a virtualization system that assigns processor time and memory space to guest systems and including a virtualization system scheduler, the method including running a first guest system that includes at least one first thread and at least one second thread running in the first guest system, and a guest system scheduler that assigns processing time to the at least one second thread, assigning a plurality of time reservations to the first guest system, wherein the plurality of time reservations include a first time reservation associated to one first thread and a second time reservation associated to the guest system scheduler of the first guest system, assigning processor time to the first guest system according to the second time reservation, and assigning processor time to the at least one first thread of the first guest system according to the first time reservation.

Abstract: The present invention relates to a method for updating a control unit (1) for an automotive vehicle, the control unit comprising a runtime system (22, 122) with a virtualization layer (32, 132) adapted to run on the processor (3), the virtualization layer being adapted to assign processor time and memory space to a plurality of guest systems (24, 26, 28, 30, 124, 126, 128, 130, 158), the method comprising: downloading (1018), by a first update client (38, 40, 138, 140) of a first untrusted guest system (26, 28) running on the virtualization layer (32, 132), one or more first update files or data segments from a first remote server (44, 46, 48, 144, 146, 148); storing, by the first update client (38, 40, 138, 140), the one or more first update files or data segments in an untrusted memory (5) accessible to the first untrusted guest system; running an update operating system (58, 158) adapted to update one or more files or data segments of the control unit; retrieving, by the updating operating system (58, 158)

Abstract: According to the invention, a motor vehicle control device is provided, comprising: a microkernel; several entities; and a software bus, via which the entities can communicate with each other and with the kernel, wherein one or more of the entities represent respectively one or more modules of the AUTOSAR base software. The present invention is based inter alia on the idea of representing the AUTOSAR architecture on a microkernel-based architecture. Thereby, the motor vehicle control device according to the invention makes it possible for example to link infotainment applications with AUTOSAR-based applications.
