Description

Technical Field

[0001] Exemplary systems and methods consistent with embodiments of the present disclosure relate to vehicle systems, and more particularly, to managing one or more updates of one or more devices in one or more vehicle systems.

Background Art

[0002] Recent vehicles are equipped with a wide range of devices that form interconnected vehicle systems. The devices include, but are not limited to, electronic control units (ECUs), infotainment systems, sensors, actuators, telematics units, and communication modules. The devices operate with each other to provide essential functions such as propulsion, safety, entertainment, connectivity, advanced driver assistance, and the like. To ensure optimal performance, safety, and user experience, and to maintain functionality, safety, and compatibility with other systems, it is important to regularly and timely update the software and firmware of the devices in the vehicle system. However, with the development of vehicle technology and the introduction of complex functions, the management of device updates has become increasingly complex and cumbersome.

[0003] One of the main factors contributing to the difficulty of processing device updates is the continuous development in vehicle functions, which has led to a continuous and significant increase in the number and variants of devices in vehicle systems, ranging from conventional functions such as in-vehicle infotainment systems to new advanced functions such as Internet of Things (IoT) functions (e.g., vehicle-to-everything (V2X)).

[0004] Furthermore, advancements in software technologies such as virtualization and containerization have enabled various devices in vehicle systems (e.g., electronic control units (ECUs)) to be deployed in software form, drastically changing the deployment and management of devices in the automotive industry. As a result, the number of software components within vehicle systems is continuously and significantly increasing. This continuous increase in the number of software components in vehicle systems exacerbates the challenge of managing updates, making it a time-consuming and error-prone process.

[0005] In this regard, systems and methods for handling device updates in vehicle systems in related technologies are insufficient to effectively address the complexity and challenges, at least for the following reasons:

[0006] First, systems in related technologies lack a centralized management method for handling device updates. For example, in conventional vehicle systems, device updates are typically performed individually, requiring manual intervention for each device (e.g., the user must send the vehicle and / or associated devices to the vehicle manufacturer for updates, or a technician must physically visit the device and perform the update there). This method is time-consuming, error-prone, and inefficient, especially in scenarios where multiple devices within a vehicle system require simultaneous updates.

[0007] Furthermore, systems in related technologies often lack standardized and streamlined update processes. Each device has its own unique update mechanism, potentially requiring separate tools, procedures, and protocols. This fragmentation in the update process leads to inconsistencies, compatibility issues, and challenges when coordinating updates across different devices within a vehicle system.

[0008] Furthermore, systems in related technologies cannot provide efficient and effective coordination among users when managing device updates. Specifically, complex functions in vehicle-related systems often involve multiple users and stakeholders, and therefore, coordinating and managing device updates across various users can be difficult, especially when different users have different preferences, requirements, or usage patterns. Ensuring that all users have access to the latest updates and that updates do not interfere with each other's workflows or preferences presents a significant challenge. Consequently, the process of updating devices, such as updates to the device's operating system (OS) or firmware, can be complex, especially when updates (e.g., updated OS, updated firmware, etc.) are provided by users / stakeholders different from the user managing the device.

[0009] Furthermore, systems in related technologies cannot effectively handle different types of updates. In particular, temporary updates, often required for specific operations or scenarios, can be especially difficult to manage. For example, whenever a temporary update or change is needed for a device, the update / change may be applied to root software files (e.g., the root OS image file). Therefore, the root system image file can drift from a known point in time, and restoring the image file to its original state after the temporary update is no longer needed can be time-consuming and complex.

[0010] Taking at least the above into consideration, there is a need to provide improved systems, methods, devices, and the like for managing device updates in vehicle systems. [Overview of the project]

Specifically, a user may access the device management system 110 via an associated UE to manage one or more device updates. For example, a user may use the device management system 110 via an associated UE to search for one or more available device updates, to schedule one or more device updates, to configure one or more device updates, to perform one or more device update deployments, to publish one or more device updates, and similar purposes. Furthermore, a user may also use the device management system 110 to retrieve (e.g., view, download, etc.) information associated with one or more device updates (e.g., device update content, device update type, device update creator, etc.).

[0041] According to one or more exemplary embodiments, one or more of the plurality of UE120-1 to 120-N may include computing devices (e.g., desktop computers, laptop computers, tablet computers, handheld computers, smart speakers, servers, etc.), mobile devices (e.g., smartphones, etc.), wearable devices (e.g., a pair of smart glasses or smartwatches), SIM-based devices, or any other suitable devices that can be associated with one or more users.

[0042] According to one or more exemplary embodiments, at least a portion of the plurality of UE120-1 to 120-N may be located in different geographical locations. For example, a first portion of the plurality of UE120-1 to 120-N may be used by a first user (e.g., a developer of software updates for a first device), and the first user and associated UE may be located in a first location, while a second portion of the plurality of UE120-1 to 120-N may be used by a second user (e.g., an administrator of a first device), and the second user and associated UE may be located in a second location different from the first location.

[0043] According to one or more exemplary embodiments, devices 130-1 to 130-N may include one or more remote devices associated with a vehicle system. In this regard, the remote devices described herein may refer to electronic components, subsystems, and / or modules that are interconnected (e.g., via a network 150) and can communicate with one or more systems (e.g., a device management system 110) and one or more devices (e.g., UEs 120-1 to 120-N, a database 140, etc.). The devices are - Devices associated with control units in a vehicle, such as electronic control units (ECUs), transmission control units (TCUs), body control modules (BCMs), and similar devices. - Vehicle infotainment systems and functions such as audio / video entertainment systems, navigation systems, connectivity features, user interfaces, and similar devices. - Telematics devices such as components responsible for vehicle communication and remote monitoring, enabling services such as remote diagnostics, vehicle tracking, and emergency assistance. - Sensor devices such as devices that collect data from various sensors, including those related to ADAS (Advanced Driver-Assistance Systems) or environmental monitoring. This may include, but is not limited to, the following:

[0044] Furthermore, or alternatively, devices 130-1 to 130-N may include other types of devices within the vehicle system that require update management. Each of these devices may have embedded or incorporated software or firmware that, when performed by the device, performs one or more associated operations.

[0045] Furthermore, one or more of the devices 130-1 to 130-N may be one or more remote devices located in geographical locations different from the device management system 110, one or more of the UEs 120-1 to 120-N, and / or the database 140. These remote devices may be interconnected with the device management system 110, the database 140, and / or the UEs 120-1 to 120-N via the network 150, and their associated software / firmware may be remotely updated by the device management system 110 via over-the-air (OTA) update capabilities. Similarly, at least some of the devices 130-1 to 130-N may be located in geographical locations different from other parts of the devices 130-1 to 130-N.

[0046] Referring still to Figure 1, the database 140 may include a server, repository, or any suitable device that can be configured to store data or information associated with device updates. According to the embodiment, the database 140 may leverage the indexing and querying capabilities of a database (e.g., PostgreSQL) when storing and supplying device updates. Thus, the database 140 can efficiently manage and retrieve device updates (and / or associated data and information) based on various criteria such as device model, software version, schedule, planned release date, device location, and similar.

[0047] Network 150 may include one or more wired and / or wireless networks, which may be configured to connect a device management system 110, a plurality of UEs 120-1 to 120-N, a plurality of devices 120-1 to 120-N, and a database 140 to each other.

[0048] For example, network 150 may include cellular networks (e.g., fifth-generation (5G) networks, long-term evolution (LTE) networks, third-generation (3G) networks, code division multiple access (CDMA) networks, etc.), public land mobile networks (PLMN), local area networks (LANs), wide area networks (WANs), metropolitan area networks (MANs), telephone networks (e.g., public switched telephone networks (PSTNs)), private networks, ad hoc networks, intranets, the Internet, fiber optic-based networks, or similar, and / or combinations of these types or other types of networks.

[0049] According to one or more exemplary embodiments, the network 150 may include a virtual network, which may include one or more physical network components (e.g., Ethernet, WiFi modules, telecommunications network hardware, etc.) on which one or more virtualization network functions (e.g., a Control Area Network (CAN) bus, etc.) are implemented.

[0050] According to one or more exemplary embodiments, the network 150 may be utilized by the device management system 110 for OTA device updates on one or more of the devices 130-1 to 130-N. In this way, OTA communication between the device management system 110 and the devices 130-1 to 130-N enables efficient and secure device updates, thereby allowing the device management system 110 to securely and reliably manage and distribute device updates in the form of data packages, while enabling the device to receive updates in a timely manner.

[0051] Referring to Figure 1, the components and configurations included in the system architecture 100 described above are merely exemplary embodiments, and it can be understood that, without departing from the scope of this disclosure, the system architecture may include more or fewer components than those described, and / or the components included therein may be arranged in any way different from that described.

[0052] For example, according to one or more exemplary embodiments, the system architecture 100 may include one or more proxy servers connecting devices 130-1 to 130-N to a device management system 110 via a network 150 to manage incoming and / or outgoing network traffic and provide functions such as load balancing, routing, security, and observability; one or more network load balancers connecting devices 130-1 to 130-N to one or more proxy servers; and similar. Furthermore, the system architecture 100 may also include one or more virtual private networks (VPNs) connecting UEs 120-1 to 120-N to a device management system 110.

[0053] Next, referring to Figure 2, which shows a block diagram of exemplary components of a device management system 200 according to one or more embodiments. The device management system 200 may be similar to the device management system 110 in Figure 1.

[0054] As shown in Figure 2, the device management system 200 may include at least one communication interface 210, at least one storage 220, and at least one processor 230. According to the embodiment, the device management system 200 (or one or more components contained therein) may be deployed in a server (e.g., a cloud server, a hybrid cloud server, a server cluster, etc.).

[0055] The communication interface 210 may include transceiver-like components (e.g., transceivers, separate receivers and transmitters, buses, etc.) that enable the device management system 200 (or one or more components contained therein) to communicate with one or more components outside the device management system 200 via wired connections, wireless connections, or a combination of wired and wireless connections.

[0056] For example, the communication interface 210 may connect the device management system 200 (or one or more components contained therein) to multiple UEs (e.g., UE120-1 to 120-N in Figure 1), multiple devices (e.g., devices 130-1 to 130-N in Figure 1), and / or a database (e.g., database 140 in Figure 1), thereby enabling them to communicate with each other and operate in relation to one another. As another example, the communication interface 210 may enable the components of the device management system 200 to communicate with each other. For example, the communication interface 210 may connect the storage 220 to the processor 230, thereby enabling them to communicate with each other and operate in relation to one another.

[0057] The communication interface 210 may include hardware-based interfaces, such as bus interfaces, Ethernet interfaces, optical interfaces, coaxial interfaces, infrared interfaces, radio frequency (RF) interfaces, Universal Serial Bus (USB) interfaces, Wi-Fi interfaces, cellular network interfaces, software interfaces, or similar. According to embodiments, the communication interface 210 may include at least one controller area network (CAN) bus, which can be configured to connect components of the device management system 200 (e.g., storage 220, processor 230, etc.) to a plurality of UEs (e.g., UE120-1 to 120-N), a plurality of devices (e.g., devices 130-1 to 130-N), and / or a database 140 in a communicative manner. Furthermore or alternatively, the communication interface 210 may include software-based interfaces, such as application programming interfaces (APIs), virtualized network interfaces (e.g., virtualized CAN buses, etc.), or similar.

[0058] The communication interface 210 may be configured to receive information from one or more components outside the device management system 200 and provide such information to the processor 230 for further processing and / or to the storage 220 for storage. For example, the communication interface 210 may receive one or more user inputs from multiple UEs regarding the management of one or more device updates (e.g., browsing available updates, browsing device information, scheduling device update deployments, triggers for device update deployments, configuration or modification of device updates, etc.) and provide such user inputs to the processor 230 and / or storage 220. Similarly, the communication interface 210 may be configured to enable the processor 230 of the device management system 200 to provide one or more pieces of information to one or more components outside the device management system 200.

[0059] Still referring to Figure 2, at least one storage 220 may include one or more storage media suitable for internally storing data, information, and / or computer-readable / computer-executable instructions. According to embodiments, the storage 220 may include random-access memory (RAM), read-only memory (ROM), and / or other types of dynamic or static storage devices (e.g., flash memory, magnetic memory, and / or optical memory) for storing information and / or instructions for use by the processor 230.

[0060] Furthermore, or alternatively, storage 220 may include, along with a corresponding drive, hard disks (e.g., magnetic disks, optical disks, magneto-optical disks, and / or solid-state disks), compact discs (CDs), digital versatile discs (DVDs), floppy disks, cartridges, magnetic tapes, and / or other types of non-temporary computer-readable media.

[0061] The storage 220 may be configured to store information used by the processor 230 to perform one or more operations to manage one or more updates for one or more devices. For example, the storage 220 may be configured to store one or more device update deployment settings provided by one or more users, to store information associated with one or more users and / or update deployments associated with a device, to store information for one or more devices, to store device updates received from a database, and similar things.

[0062] At least one processor 230 may be configured to receive one or more signals (for example, via a communication interface 210, etc.) that define one or more instructions that perform one or more operations. Furthermore, the processor 230 may be implemented in hardware, firmware, or a combination of hardware and software. The processor 230 may include a central processing unit (CPU), an image processing unit (GPU), an accelerator processing unit (APU), a microprocessor, a microcontroller, a digital signal processor (DSP), a field-programmable gate array (FPGA), an application-specific integrated circuit (ASIC), and / or other types of processing or computing components.

[0063] At least one processor 230 may include one or more processors programmable to perform functions or operations that manage one or more device updates. For example, processor 230 may be configured to execute computer-readable instructions stored in memory storage (e.g., storage 220, etc.) to perform one or more actions or operations described herein.

[0064] Referring to Figure 2, the components and configurations of the device management system 200 described above are merely exemplary embodiments, and it can be understood that, without departing from the scope of this disclosure, the device management system 200 may include more or fewer components than those described, and / or the components included therein may be arranged in any way different from that described.

[0065] For example, according to one or more exemplary embodiments, the device management system 200 may include input modules (e.g., touchscreen displays, buttons, switches, microphones, sensors, keyboards, mice, joysticks, keypads, soft keys, etc.) and / or output modules (e.g., displays, speakers, bell devices, one or more light-emitting diodes (LEDs), LED-based displays, e.g., active-matrix organic light-emitting diode (AMOLED) displays, thin-film transistor (TFT) displays, liquid crystal displays, etc.) that can be configured to receive one or more user inputs from one or more users and / or output information to one or more users.

[0066] Next, referring to Figure 3, which shows a flowchart of an exemplary method 300 for managing one or more updates relating to one or more devices in a vehicle system according to one or more embodiments. One or more operations of method 300 may be performed by at least one processor of a device management system (e.g., processor 230) when a computer executable instruction stored in at least one storage medium (e.g., storage 220) is executed.

[0067] As shown in Figure 3, in operation S310, at least one processor of the device management system may be configured to retrieve information associated with one or more device updates (which may be referred to herein as “update information”). According to embodiments, at least one processor may retrieve update information from a user. Alternatively or further, at least one processor may retrieve update information from a database and / or build system. A description of exemplary use cases in which update information is received is provided below with reference to the exemplary use case in Figure 4.

[0068] Upon obtaining update information, method 300 may proceed to operation S320, in which at least one processor of the device management system may be configured to generate one or more messages associated with the update (which may be referred to herein as “update messages”) based on the obtained update information. For example, at least one processor may determine, based on the obtained update information, the type of update (e.g., temporary update, mandatory update, optional update, etc.), the importance of the update (e.g., urgent update, non-urgent update, update associated with safety function, etc.), and similar information. Thus, at least one processor may generate an update message based on the determined information. The update message may include update information, such as device identification information, the type of update (e.g., temporary update, non-temporary update, etc.), the importance / urgency of the update, the update version, the deployment schedule, the update's memory information, and similar information.

[0069] Therefore, in operation S330, at least one processor may configure the deployment of an update. For example, at least one processor may provide an update message to the device to be updated (which may be referred to herein as the “target device”), thereby instructing the target device to configure the deployment of an update. According to embodiments, at least one processor may be configured to generate and provide an update message to the target device in order to cause the target device to configure a non-temporary update (a description of exemplary use cases associated therewith is provided below with reference to Figures 5A-5B). According to embodiments, at least one processor may be configured to generate and provide an update message to the target device in order to cause the target device to configure a temporary update (a description of exemplary use cases associated therewith is provided below with reference to Figure 6).

[0070] Next, referring to Figure 4, which shows a block diagram of an exemplary system configuration 400 that provides update distribution according to one or more embodiments. As shown in Figure 4, the system configuration 400 may include a device management system 410, a build system 420, a device 430, and a database 440. The device management system 410 and the database 440 may be similar to those described herein with reference to other figures, the build system 420 may be similar to the UE described herein with reference to other figures, and the device 430 may be similar to the target device described herein with reference to other figures. Furthermore, one or more operations in Figure 4 may be similar to one or more operations in method 300 of Figure 3.

[0071] In the example in Figure 4, a first user (e.g., a software developer) may use the build system 420 (in operation S401) to create or build an update for device 430. Once a device update is built or created, the build system 420 may be configured to provide the update to the database 440 (e.g., via network 150), and the database 440 may be configured (in operation S402) to store the device update internally.

[0072] Therefore, a second user (e.g., an administrator of device 430) may access the device management system 410 (e.g., via an associated UE, direct access without a UE, etc.) to manage device updates (in operation S403), for example, by scheduling device update deployments, executing device update deployments, and similar actions. In this operation, the device management system 410 (or at least one processor contained therein) may receive update information from the second user. In this regard, the device management system 410 may be configured to generate and output one or more graphical user interfaces (GUIs) and output one or more GUIs to the second user (via an input / output module). Therefore, the device management system 410 may receive user input from the second user by determining user interaction with one or more GUIs.

[0073] Furthermore, or alternatively, the device management system 410 may (in an optional operation S403-1) obtain or receive update information from the build system 420, and / or (in an optional operation S403-2) obtain or receive update information from the database 440.

[0074] Upon acquiring update information, the device management system 410 (or at least one processor contained therein) may be configured to generate one or more update messages based on the update information. Thus, the update messages may be provided to the device 430 (in operation S404). One or more operations performed by the device management system, such as receiving update information and / or providing update messages, may be performed via OTA.

[0075] Upon receiving an update message from the device management system 410, device 430 may be configured to retrieve or obtain a device update from the database 440 based on the update message (in operation S405). Thus, device 430 may configure a device update deployment based on the retrieved device update and the update message. An exemplary use case of a device configuring a device update deployment is provided below with reference to Figures 5A to 56.

[0076] First, referring to Figure 5A, which shows a block diagram of a first configuration of an exemplary use case for deploying a device update according to one or more embodiments. In the example of Figure 5A, it is assumed that device 530 (which may be similar to device 430 in Figure 4) has received an update message from a device management system (e.g., device management 410 in Figure 4) and has determined that the type of update is a non-temporary update (e.g., a mandatory update, an optional update, etc.).

[0077] As shown in Figure 5A, device 530 may include a first part 531 and a second part 532, each of which may have a first version of software (indicated as “Software Version 1” in Figure 5A). In this regard, one of parts 531 and 532 may be configured to store the primary software that the device runs on, and the other of parts 531 and 532 may be configured to store a cloned version of the software for backup, redundancy, or any other preferred purpose. According to embodiments, the software may include an operating system (OS) image.

[0078] In this regard, device 530 may determine the required device update based on the update message and may retrieve the update from database 540 (which may be similar to database 440 in Figure 4). For example, assuming the update message indicates that the update is a non-temporary update that updates the software from "version 1" to "version 1.1", device 530 may retrieve the update (e.g., software version 1.1) from database 540 and deploy the update accordingly. For example, the device may overwrite or replace the software in one of the first part 531 and the second part 532 with software retrieved from database 540.

[0079] Next, referring to Figure 5B, which shows a block diagram of a second configuration of an exemplary use case for deploying a device update according to one or more embodiments. The components of Figure 5B may be the same as those described above with reference to Figure 5A.

[0080] In the example in Figure 5B, it is assumed that device 530 has acquired the device update “Software Version 1.1,” which overwrites or replaces the software in the second portion 532 (indicated as “Software Version 1” in Figure 5A). The device may then switch its primary software from the software in the first portion 531 (e.g., “Software Version 1”) to the updated software in the second portion 532 (e.g., “Software Version 1.1”). Next, device 530 may restart or resume to switch the running software to the new primary software.

[0081] It can be understood that device 530 may be configured to deploy non-transient device updates in any other preferred manner and / or in a similar manner, without departing from the scope of this disclosure.

[0082] Referring to Figure 6, which shows a block diagram of an exemplary use case configuration for deploying a temporary device update according to one or more embodiments. In the example of Figure 6, it is assumed that device 630 (which may be similar to device 440 in Figure 4) has received an update message from a device management system (e.g., device management 410 in Figure 4), has determined that the update type is a temporary update (e.g., a software beta version update, a temporary hotfix, or an update for testing purposes), and has retrieved the device update from a database (e.g., database 430 in Figure 4).

[0083] As shown in Figure 6, device 630 may include an overlay file system 631 which includes an upper layer 631-1 and a lower layer 631-2. These layers 631-1 and 631-2 may be contained in one or more of the first part 531 and the second part 532. Furthermore, each of layers 631-1 and 631-2 may contain the same software files, and the upper layer 631-1 and / or the software files contained therein may be temporarily created by device 630 based on the lower layer 631-2 and the software files contained therein.

[0084] Specifically, based on the determination from the update message provided by the device management system that the update is a temporary update, device 630 may create a reference or pointer to the software file in the lower layer 631-2, allowing device 630 to continue executing the software file in the lower layer 631-2 for normal operation without interruption.

[0085] Subsequently, device 630 may then begin creating a temporary copy of the software file and include the copied software file within the upper layer 631-1 to which the temporary update is applied. Thus, the temporary update is performed in the upper layer 631-1, ensuring that the original software file in the lower layer 631-2 remains intact and uninterrupted during the temporary update process. According to one embodiment, device 630 may be configured to remove the software file in the upper layer 631-1 after a certain period of time (for example, after a predetermined amount of time specified in the update message, or after device 630 has been restarted), thereby allowing device 630 to revert to its last known state.

[0086] Considering the above, software files in the upper layer 631-1 may be referred to as "read-write files," while software files in the lower layer 631-2 may be referred to as "read-only files." According to the embodiment, device 630 may utilize a copy-on-write (CoW) mechanism when managing the overlay file system 631. Thus, the transient update process can be more efficient and resource-friendly, ensuring minimal disruption to the normal operation of device 630. Furthermore, reversible updates are provided, thereby minimizing the risk of potential problems such as state drift of device 630.

[0087] To this end, exemplary embodiments of the present disclosure provide a device management system (and a method of utilizing such a device management system) that enables the effective and efficient management of one or more updates of one or more devices in a vehicle system, and then addresses the problems in the related technologies described above.
