Definitions
- the invention relates to a control device for a user interface of a motor vehicle, having a one-chip system with at least one main processor and a flash memory arrangement that can be used by the one-chip system, the one-chip system comprising a hypervisor that has a first virtual machine and a second virtual machine implemented, the first virtual machine for executing at least one first, in particular relevant for the ferry operation of the motor vehicle, function and the second machine for executing at least one second function, in particular infotainment function for the user , is formed, wherein at least one availability requirement and / or safety requirement and / or robustness requirement and / or driving readiness requirement for the at least one first function is higher than for the at least one second function.
- the invention relates to a motor vehicle and a method for operating a control device for a user interface of a motor vehicle.
- HCP High Performance Computing Platform
- a common cockpit HCP as a control device for the user interface, which on the one hand provides infotainment / entertainment functionalities, but on the other hand also functions that support the driving of the motor vehicle itself by corresponding driving-related content / warning displays are generated, which can then be output, for example, in a combination instrument and / or on a flead-up display and / or via an audio system of the motor vehicle.
- Functions of such a control device that are relevant for the ferry operation, in particular the general readiness to drive the motor vehicle also include functions related to a reversing camera, the operation of an air conditioning system and the like.
- Such a control device for a user interface of a motor vehicle can therefore also be referred to overall, in addition to the term cockpit FICP or cockpit control device, as a user input / output control device.
- this approach means that functions are integrated in a common cockpit control unit which have extremely conflicting requirements with regard to the robustness, safety and driveability of the motor vehicle. While the requirements for robustness and safety for the infotainment functions are lower, they are extremely high for the functions related to driving and the motor vehicle. Correspondingly, infotainment / entertainment functionalities are not necessary in order to make the vehicle ready to drive, while a specific set of functions exists in the domain relating to the ferry operation and the motor vehicle, which is essential for the vehicle to be ready to drive.
- a hypervisor that implements two virtual machines, namely a first virtual machine (SYS_Partition) for functions with requirements with regard to the early availability, robustness, safety and readiness to drive the motor vehicle, and a second virtual machine (IVI_Partition), which provides second functions that relate to info tainment (including entertainment).
- the flypervisor provides the virtualization of common hardware resources to the two virtual machines, including access to the storage means, which is usually seen as a flash storage device.
- a special problem in this context arises from the use of open infotainment or entertainment operating systems, such as “Android Automotive”.
- the likelihood that the connected flash storage device, usually UFS, eMMC or SSD, will be damaged is significantly higher than that of a conventional infotainment or entertainment system, since, for example, application software from third-party providers is to be provided and used, for which the flash memory access cannot be controlled.
- the “Android Automotive” platform itself for example, requires a higher number of write operations to the flash memory than a conventional infotainment or entertainment system.
- Flash Wear Leveling is a technique for extending the service life of various erasable storage media, especially flash memory. The idea in this context is to arrange data in such a way that deletion and rewriting processes are evenly distributed across the entire medium.
- SLC Single-Level Cell
- MLC Multiple-Level Cell
- TLC Multiple-Level Cell
- SD cards As additional storage means.
- the addition of an SD card slot in the motor vehicle would cause additional costs and require a spe cial installation space.
- the memory access times for SD cards are significantly lower than for embedded flash memory.
- a pure monitoring activity of this kind does not sufficiently prevent the wear and tear of the flash memory, so that failures can still occur in control devices for user interfaces in motor vehicles during the life of the motor vehicle.
- WO 2015/103 376 A1 discloses a vehicle with several user interface control domains.
- the document discloses a computer system for integration with a user interface of a vehicle, which has a computing system with at least one multi-core processor.
- the computing system is set up to provide virtualization for a first guest operating system and for a second guest operating system.
- the first guest operating system is configured for highly reliable operation, the virtualization preventing measures of the second guest operating system from influencing the highly reliable operation of the first guest operating system.
- US 2017/0021 839 A1 discloses methods and systems for the algorithmic control of automotive functions.
- the system there comprises a multi-core one-chip system with a hypervisor which provides a multi-core synchronization function for a plurality of cores on the one-chip system.
- US 2017/0 039 084 A1 relates to an expanded, advanced driver assistance system (ADAS) as a one-chip system.
- ADAS advanced driver assistance system
- a hypervisor can provide different virtual machines, which can include, for example, an ADAS server, a virtual machine for at least security-critical functions of the ADAS and a virtual machine for non-critical security functions.
- DE 10 2011 122 344 A1 relates to a method for managing data in a flash memory of a driver assistance device of a motor vehicle.
- the flash memory comprises at least a first and a second memory sector in which the data are stored.
- the data include critical data, the lack of which leads to a failure of the driver assistance device, as well as non-critical data, with all critical data being stored in at least one of the memory sectors.
- the invention is based on the object of providing a possibility for integrating functions and infotainment functions related to the ferry operation on a common flypervisor-based system with a common flash access, which ensures the availability of the functions related to the ferry operation and the motor vehicle over the life of the Motor vehicle ensures.

- a control system is proposed, specifically a split cockpit / infotainment control system, which has a one-chip system (system on a chip, SoC) and two flash memory units of a flash memory arrangement, each with the one-chip system are connected.
- the one-chip system includes a flypervisor, for example as firmware, which creates and operates virtual machines and provides the virtualization of the one-chip system resources, for example main processor (main CPU), I / Os, and so on.
- main CPU main processor
- I / Os I / Os
- first flash memory unit and a second flash memory unit By providing a first flash memory unit and a second flash memory unit, independently addressable memory sections are created, which are also independent of one another in their operation, so that a long-lasting flash memory unit can be created through the targeted distribution of the necessary memory information for the control device, which is sufficient for the control device to continue to operate, and to provide a flash memory unit with which there is a risk of an earlier failure, but which then does not question the functionality of the control unit as a whole. It is therefore proposed that not only all the data necessary to start up the control device, in particular a bootloader, be stored on the first flash memory unit, but also the software means implementing the hypervisor, all software means of the first virtual machine and the infrastructure software, especially the operating system and a framework of the operating system, the second virtual machine.

- the division of information to be stored is selected such that the control device is bootable and executable both with and without the availability of the second flash memory unit.
- the invention therefore makes it possible, in particular, to allow the execution of lower requirements-fulfilling second functions that are implemented by the application software means of the second virtual machine in the second flash memory unit, but which, however, place a significantly higher load on the flash memory, without the more demanding requirements. in particular to impair the first functions relevant or necessary for the operation of the motor vehicle or to expose the flash memory unit to a greater risk of suffering a defect.
- infotainment functions including information functions and entertainment functions
- infotainment functions can be executed on open application platforms such as “Android Automotive” in parallel with functions that are assigned to the ferry operation of the vehicle on the same calculation platform without affecting the lifetime of the ferry operation of the vehicle-related first functions is impaired, even if it cannot be prevented that the flash memory for the infotainment functions (second functions) suffers a defect much earlier, for example due to the behavior of third-party applications, due to the nature of certain Use cases and / or due to malfunction of malicious applications.
- An expedient development of the present invention provides that the motor vehicle in which the control device according to the invention is installed is assigned a different, longer guarantee period for the functions in the first flash memory unit than for the, in particular complete, second functions in the second flash memory unit.
- the guarantee period for the functions in the first flash memory unit can correspond to the guarantee period of the entire motor vehicle and the guarantee period for the functions in the second flash memory unit can be shorter, for example corresponding to the expected service life of the second flash memory unit.
- the invention allows a marketing variant for motor vehicles in which an infotainment platform is sold with a shorter warranty period than other vehicle functions.
- “Android Automotive” for the second virtual machine, even if this operating system and its application software do not cause a defect in the second flash memory unit, the service life of "Android Automotive" within a motor vehicle can be limited, guaranteed for a few years after Android hardware support.

- OEM software or OEM applications can already be provided by the manufacturer, i.e. by the manufacturer of the motor vehicle, in which a correspondingly heavy wear and tear of the flash memory is prevented.
- This means that such second functions can in principle also be implemented via the first flash memory unit, which gives the manufacturer the flexibility to also save certain OEM functionalities of the second virtual machine as application software on the first flash memory unit and thus even if the second flash memory unit fails to keep available.
- a particularly advantageous embodiment of the present invention accordingly provides that at least one basic software means provided by the manufacturer for the second virtual machine is additionally stored in the first flash memory unit and / or a storage space is reserved for the basic software means.

- FIG. 1 shows the architecture of a control device according to the invention
- FIG. 2 shows a schematic diagram of a motor vehicle according to the invention.
- the control device 1 shows the architecture of a control device 1 according to the invention for a user interface of a motor vehicle, which can also be referred to as a cockpit FICP.

- the control device 1 further comprises a flash memory arrangement 7, which has a first flash memory unit 8 and a second flash memory unit 9.
- the flash memory units 8, 9 are each connected to the one-chip system 2.
- the flash memory units 8, 9 are both provided as separate flash memory modules, ie separate structural units; however, it is also conceivable to use a single flash memory module with two flash memory zones that are independent of one another.
- the resources of the one-chip system 2 and of the flash memory arrangement 7 are managed and virtualized by a flypervisor 10, in the present case for implementation by a first virtual machine 11 and a second virtual machine 12.
- the first virtual machine 11 performs first functions that are relevant for the ferry operation of the motor vehicle, for example the controls of a combination instrument, the output of warnings and the like. In particular, at least some of the first functions must be available for the motor vehicle to be ready to drive.
- These first functions classic functions of a cockpit control unit, have high requirements in terms of early availability, robustness and safety and are at least partially necessary for the vehicle to be ready to drive.
- the second virtual machine 12 performs information tainment functions as second functions, that is to say functions related to information output and / or entertainment.
- These second functions have significantly lower requirements with regard to early availability, robustness and security. They are not required for the vehicle to be ready to drive.
- the second functions in particular as third-party software means and / or when using open operating systems, can include a significantly larger number of accesses to the flash memory, in particular of erasure and write access, which means the wear and tear of the flash memory due to at least part of the second functions is significantly higher than that of the first functions. This is in particular also due to the fact that in the second virtual machine 12 the user is given the option of installing application software himself, for example problematic third-party software in addition to OEM software provided by the manufacturer.

- OEM software application software means provided by the manufacturer
- third-party software means are stored in the second flash memory unit 9, and consequently all application software means that implement the second functions.
- second functions (navigation system and possibly media-related software), which are stored here in the second flash memory unit 9, also access the databases mentioned by the manufacturer in the reserved storage space 13.
- the control device 1 Due to the application software means in the flash memory unit 9 that are not relevant for the basic functions of the control device 1, the control device 1, in particular the one-chip system 2, can boot and run both with and without the availability of the second flash memory unit 9.
- the one-chip system 2 is also designed to detect the availability of the second flash memory unit 9 during the booting process. If it is determined that the second flash memory unit 9 is no longer available, for example due to excessive loading due to at least part of the second functions, for example due to a defect, various measures are taken in the present case. On the one hand, the second flash memory unit 9 is considered not longer available, so that in the future there will be no corresponding detections that could slow down the boot process.
- these basic software means include a projection mode function, a radio application for receiving radio stations and a media playback function.
- the projection mode function can be used to implement a projection mode for at least one connectable mobile device, for example a smartphone, which enables an "app" of the connected mobile device to be operated via the user interface of the motor vehicle, for example as a replacement for missing second functions.
- the databases made available by the manufacturer in the reserved storage space 13 of the first flash memory unit 8 are overwritten with the basic software means.
- the at least one basic software means is basically already stored in the first flash memory unit 8, i.e. is permanently provided there, while the remaining application software means are used to implement the second Function in the second flash memory unit 9 are stored.
- the flash memory units 8, 9 can be in UFS format, as SSD and / or eMMC. Furthermore, within the scope of the present invention it can optionally be provided that software means for at least one diagnostic function and / or at least one configuration function and / or a trusted execution environment are also stored in the first flash memory unit 8. In any case, that is to say also in this exemplary embodiment, the one-chip system 2 is, however, designed for the application of flash wear leveling to the flash memory arrangement 7, and consequently each of the flash memory units 8, 9. This means that through appropriate control of the flash memory units 8, 9, uniform use of the individual memory cells is achieved, as far as this is possible.
- Fig. 2 finally shows a schematic diagram of a motor vehicle 14 according to the invention.
- this comprises a combination instrument 15 and an operating device 16 provided in the area of the center console, in particular comprising a touch screen, with both input / output means 15, 16 both Functions relevant to ferry operations (first functions) as well as infotainment functions (second functions) can be used.
