Description

Management control method and apparatus for vehicle wireless update {METHOD AND APPARATUS FOR MANAGEMENT CONTROL OF VEHICLE OTA UPDATE}

The present invention relates to a method and apparatus for managing and controlling vehicle wireless update.

As the Intelligent Transportation System (ITS) evolves and the proportion of vehicles capable of wireless communication (e.g., WiFi, 3G, LTE, etc.) increases, the vehicle's communication with other vehicles or external entities such as infrastructure increases. Communication is also becoming commonplace.

In addition, the number of electronic control units (ECUs) in vehicles is also increasing. As the structure and functions of these electronic controllers become increasingly complex, software modules inside the electronic controllers also need to be updated for reasons such as bug fixes, performance improvements, and security improvements.

As described above, these software require updates to add new features and improve errors, but users find it cumbersome to update for various reasons, and tend not to update or postpone the update unless they feel great inconvenience. leads to a low update execution rate.

On the other hand, in general, updating of the software module inside the electronic controller uses diagnostic communication through a wired connection between the vehicle and the diagnostic device, but the speed of diagnostic communication is slow and requires a visit to a place equipped with diagnostic equipment such as a repair shop There is discomfort.

Recently, over-the-air (OTA) services for wirelessly updating software have begun to be provided, through which cost-effective software updates can be performed safely and quickly, and software recalls and related costs can be reduced.

As such, the OTA technology of vehicle controllers is currently a hot topic in the relevant field. In line with connectivity, a wireless update methodology, rather than a wired update, is emerging and market launch is imminent.

1 to 3 are diagrams illustrating a general OTA update operation of a vehicle controller.

As shown in FIGS. 1 and 2 , the normal/compressed update can download the same version regardless of the version of the model controller to be updated, thereby ensuring ease of management.

In the differential update method as shown in FIG. 3 , different images must be generated and transmitted according to the version of the model controller to be updated, and therefore, management is not easily secured.

Until now, OTA technology consists of normal, compressed, and redundant downloads, and differential update technology has not yet been applied.

However, compared to wireless communication networks whose speed has increased exponentially, low-speed communication networks such as CAN (Controller Area Network) are still the mainstream for in-vehicle communication, and even if fast wireless download is performed, in-vehicle communication that updates even the target controller is low-speed. It takes too much speed.

Therefore, in order to solve this problem, a method such as difference update is emerging, but when the version of each vehicle in the field is different, it is difficult to manage the corresponding difference data respectively, so that method is currently avoided.

Even if a low-speed in-vehicle communication network is used, the differential update method can significantly improve the update speed by significantly reducing data. However, when each vehicle has different versions, a large load is generated because difference data matched to each version must be wirelessly downloaded.

OTA update technology of vehicle controllers has a major goal to overcome excessive update time due to low-speed in-vehicle communication. In order to overcome this, it is common to reduce the size of the data in the form of compressed or differential data. Among them, the method that can reduce the size of data the most is the update method through difference, which requires updating through data in which the version to be updated and the previous version exactly match. This is currently not used because it can cause excessive management load when it is assumed that all existing vehicles have different versions.

For update, after receiving data from the server 10 to the management controller, the management controller proceeds with OTA update by updating each target controller.

In this case, while high-speed wireless communication is between the server and the management controller, the management controller and the target controller use a low-speed controller area network (CAN) in most vehicles.

The management controller is equipped with a high-performance AP because the purpose of control is not, and the purpose of the target controller is to control rather than performance, so a reliability-oriented MCU is installed.

For this reason, data transmitted at high speed from the server 10 causes a significant decrease in update speed due to low-speed CAN communication.

Embodiments of the present invention relate to over-the-air (OTA) update management control of a vehicle controller, and provide a method and apparatus for over-the-air update management and control to overcome an excessive update time due to low-speed in-vehicle communication.

Embodiments of the present invention transmit the same data to all target vehicles, and generate and update compressed data or differential data in an in-vehicle management control device to quickly perform an update even within low-speed in-vehicle communication, a vehicle. It is intended to provide a management control method and apparatus for wireless update.

However, the problem to be solved by the present invention is not limited thereto, and may be expanded in various ways even in an environment within a range that does not deviate from the spirit and scope of the present invention.

According to an embodiment of the present invention, a method for managing and controlling wireless vehicle update performed by an apparatus for managing and controlling wireless vehicle update includes downloading update data of a current version for updating a target controller wirelessly from a server; generating compressed data or difference data according to the presence or absence of an updated image of a previous version for the target controller; and transmitting the generated compressed data or difference data to a target controller to update the target controller.

In the downloading of the update data, the update data of the current version may be downloaded from the server in a general download method or a compressed download method.

In the downloading of the update data, the same update data may be downloaded at a predetermined speed or higher regardless of whether or not an update image of a previous version for the target controller exists.

In the generating of the compressed data or difference data, if there is an update image of a previous version for the target controller, difference data between the downloaded update data and the update image of the previous version may be generated.

In the generating of the compressed data or difference data, if there is no update image of a previous version for the target controller, compressed data may be generated by compressing the downloaded update data.

The method may further include, if the update of the target controller is successful, replacing the update image of the previous version and storing the update data of the current version to generate difference data at a next update time point.

On the other hand, according to another embodiment of the present invention, a first communication module for wirelessly communicating with the server; a second communication module communicating with a target controller through an in-vehicle communication network; memory for storing one or more programs; and a processor executing the one or more stored programs, wherein the processor downloads update data of a current version for updating the target controller from the server through the first communication module, and downloads update data of a previous version for the target controller. Management control of vehicle wireless update, which generates compressed data or difference data according to the presence or absence of an update image of and transmits the generated compressed data or difference data to a target controller through the second communication module to update the target controller. A device may be provided.

The processor may download the update data of the current version from the server through the first communication module in a general download method or a compressed download method.

The processor may download the same update data at a predetermined speed or higher through the first communication module regardless of whether an update image of a previous version for the target controller exists.

If there is an update image of a previous version for the target controller, the processor may generate difference data between the downloaded update data and the update image of the previous version.

If there is no update image of a previous version for the target controller, the processor may generate compressed data by compressing the downloaded update data.

If the update of the target controller is successful, the processor may replace the update image of the previous version and store the update data of the current version in the memory to generate difference data at the next update time.

The disclosed technology may have the following effects. However, it does not mean that a specific embodiment must include all of the following effects or only the following effects, so it should not be understood that the scope of rights of the disclosed technology is limited thereby.

Embodiments of the present invention relate to over-the-air (OTA) update management control of a vehicle controller, and can overcome excessive update time due to low-speed in-vehicle communication.

Embodiments of the present invention transmit the same data to all target vehicles, and generate and update compressed data or difference data in the in-vehicle management control device, thereby performing an update quickly even in low-speed in-vehicle communication.

Embodiments of the present invention overcome the low-speed in-vehicle communication environment by downloading the same data to all vehicles from the server to the vehicle, determining the compression/differential transmission method in the management control device, and generating and updating the difference in case of difference. Both problems can be overcome by reducing the system load of downloading the same data to the vehicle.

Embodiments of the present invention can improve the update speed compared to the normal and compressed data download method, and can reduce management and system load because the same data is downloaded compared to the conventional differential update method.

4 is a configuration diagram for explaining the configuration of a vehicle wireless update system to which an embodiment of the present invention is applied.

As shown in FIG. 4 , a vehicle wireless update system to which an embodiment of the present invention is applied includes a server 10 , a management control device 110 in the vehicle 100 and a target controller 120 .

The server 10 is connected to the vehicle 100 through high-speed wireless communication and transmits the same update data to each vehicle.

The management control device 110 of all vehicles downloads the same final version from the server 10 through high-speed wireless communication. The management control unit 110 previously checks the update success history for each target controller, and if there is updated data of the previous version stored, generates the latest data and the difference image downloaded from the stored update data, and transmits the difference image to each controller through low-speed CAN communication. perform an update The difference image generated in this way can be quickly updated even through a low-speed in-vehicle communication network because the amount of data itself is small.

If there is no previous update history, the management control device 110 compresses the update data to generate compressed data, and updates the corresponding target controller in the form of compression. When the continuous update is performed in this way, the target controller 120 creates a download history and becomes in a state capable of differential update, enabling rapid update.

In this way, the management control device 110 wirelessly downloads the same data (normal/compressed) at high speed when updating the controller of the vehicle through OTA. Also, the management control device 110 may select a compression/difference target using a previous update image even on a low-speed communication network such as CAN, and update the target controller 120 at high speed by minimizing update data.

The management control device 110 may generate difference data using previous data and transmit the difference data to the target controller 120 . Alternatively, the management control device 110 may transmit compressed data to the target controller 120 when previous data does not exist. The same data can be downloaded to each vehicle while being transmitted at high speed using the compression/difference determination and generation transmission functions of the management control device 110 .

5 is a diagram illustrating a vehicle wireless update operation in the management control device 110 according to an embodiment of the present invention.

An embodiment of the present invention is a method for a method that is easy to manage and has a fast update speed by complementing both the difficulty in managing the differential data method and the slow update speed of normal/compressed update.

As shown in FIG. 5 , the management and control device 110 of the vehicle 100 downloads the same data from the server 10 to all target controllers 120 of the same vehicle in a compressed form at high speed.

With the data downloaded in this way, the management control device 110 checks whether an update history exists in the corresponding vehicle. If there is no update history, the compressed download image is stored in the file system of the management control device 110 .

After storage is completed, the management control device 110 transmits the compressed data to the target controller 120, and the target controller 120 releases the compressed data and proceeds with the update.

If there is a download history, since the compressed data of the previous version is stored in the file system, the management control device 110 releases both the compressed data of the previous version and the currently downloaded compressed data of the current version to extract the difference data. do.

The management control device 110 transmits the extracted difference data to the target controller 120 . The target controller 120 performs an update by releasing difference data.

Since the management control device 110 is equipped with a high-performance AP (Application Processor), there is little time required for compression and difference creation and release.

For example, the management control device 110 stores compressed data downloaded for target controller 1 (121, no update history) in a non-volatile memory. The management control device 110 transmits the downloaded compressed data to the target controller 120 .

The management control device 110 decompresses the update data of the previous version for the target controllers 2 and 3 (122 and 123, there is an update history). The management control device 110 decompresses the downloaded compressed data. The management control device 110 generates difference data between update data and download data of a previous version. The management control device 110 transmits the difference data to the target controllers 2 and 3 (122 and 123).

The target controller 1 (121), which has no update history, receives the compressed data of the V2.0 version and proceeds with the update.

The target controller 2 (122) having an update history receives the difference data between the previous versions V1.1 and V2.0 and proceeds with the update.

The target controller 2 (122) having an update history receives the difference data between the previous versions V1.2 and V2.0 and proceeds with the update.

Since the target controller 120 in the initial state does not have a download image, it updates in a compressed form. However, since data of the previous version exists in the target controller 120 that has been updated at least once during the continuous update, differential data can be generated. As the number of target controllers 120 that have been updated in the corresponding vehicle increases, the number of target controllers 120 capable of generating difference data increases, and thus the update time continuously decreases.

6 to 8 are views illustrating operations in which a method for managing and controlling wireless vehicle update according to an embodiment of the present invention is repeatedly performed.

6 is an initial state and a process of downloading update data for target controllers 1 and 2 (121 and 122). For all target controllers 1, 2, and 3 (121, 122, and 123), since the management control device 110 does not have update data for the previous version (currently running version), the downloaded update image is stored and the target controller Compressed data is transmitted to 1 and 2 (121 and 122).

FIG. 7 shows a process of downloading update data for target controllers 2 and 3 (122 and 123) for the next event after FIG. 6 is performed. At this time, some target controllers, that is, target controllers 1 and 2 (121, 122) have update data for previous versions. Therefore, the management control device 110 can generate difference data for the image of the target controller 2 122 having the previous version, and transmits the difference data. Still, for the target controller 3 (123), since there is no update data for the previous version, the management control device 110 transmits compressed data to the target controller 3 (123).

FIG. 8 shows a process of downloading update data for target controllers 1, 2, and 3 (121, 122, and 123) for the next event after FIG. 7 is performed. At this time, since all target controllers have data for the previous version, the management control device 110 can generate difference data and transmits the difference data.

6 to 8, as the number of updated target controllers increases, the number of target controllers capable of generating a difference increases. Accordingly, the download speed of the update data is reduced, and if all target controllers have an update experience at least once, all controllers perform differential update. In this way, the update rate gradually decreases.

9 is a flowchart of a method for managing and controlling vehicle wireless update according to an embodiment of the present invention.

In step S101, the management control device 110 wirelessly downloads compressed update data from the server 10.

In step S102, the management control device 110 checks whether there is a previous version (current image) of the target controller.

In step S103, the management control device 110 transmits the compressed data to the corresponding target controller if there is no updated data of the previous version.

In step S104, the management control device 110 decompresses the update image of the previous version (current image) if there is update data of the previous version.

In step S105, the management control device 110 decompresses the downloaded update image of the current version.

In step S106, the management control device 110 generates difference data between the decompressed previous version and the downloaded current version of the image.

In step S107, the management control device 110 transmits the generated difference data to the target controller having the update data of the previous version.

In step S108, the management control device 110 checks whether the transmission of the compressed or differential update data and the update of the target controller are successful.

In step S109, if the update is successful, the management control device 110 stores the image of the current version downloaded from the server 10 as update data of the current version in memory. The updated image of the previous version stored in this way is used for the next update.

In step S110, the management control device 110 records an update error if the update fails.

As such, the management control device 110 receives compressed data using high-speed wireless communication when a download event occurs.

And, if the previous version (current image) does not exist, the management control device 110 transmits it to the target controller as it is in the downloaded compressed format. When transmission and update are successfully completed, the management control device 110 writes the corresponding image to the memory in which the previous version (current image) is stored.

Alternatively, the management control device 110 generates difference data after decompressing both the previous version and the downloaded image if the previous version (current image) exists. The management control device 110 transmits the generated difference data to the target controller, and if the update is successfully completed, the downloaded image is written to the memory in which the previous version (current image) is stored.

In this way, data corresponding to the version currently being driven in each target controller is always stored in the previous version memory except for the initial state, and is used to generate a difference at the next update time.

10 and 11 show a wireless update operation before an embodiment of the present invention is applied, and FIG. 12 shows a wireless update operation after an embodiment of the present invention is applied.

As shown in FIG. 10, the server 10 compresses the same V2.0 version data and transmits it to each vehicle. Wireless update in the vehicle 100 operates as a slow update.

As shown in FIG. 11 , the server 10 transmits difference data V1.0 to V2.0, difference data V1.1 to V2.0, and difference data V1.2 to V2.0, that is, to each vehicle differently. In this case, it operates as a high-speed update.

As shown in FIG. 12, the server 10 compresses the same V2.0 version data and transmits it to each vehicle. When the same data is received by the management control device 110 in the form of compression, the management control device 110 generates difference data and performs an update through a low-speed in-vehicle communication network. Therefore, FIG. 12 transmits the same data from the server 10 and updates each target controller at high speed using the in-vehicle communication network.

13 and 14 are diagrams illustrating an application embodiment of a download method in a method for managing and controlling wireless vehicle update according to an embodiment of the present invention.

As shown in FIG. 13 , as the first embodiment, the management and control device 110 of the vehicle 100 downloads update data for target controllers 2 and 3 (122 and 123) in a general download method. In addition, the management control device 110 of the vehicle 100 generates and updates difference data for the target controller 2 (122) having the previous version, and compresses data for the target controller 3 (123) having no previous version. Create and update.

As shown in FIG. 14 , as the second embodiment, the management and control device 110 of the vehicle 100 downloads update data for target controllers 2 and 3 (122 and 123) in a compressed download method. Then, the management control device 110 of the vehicle 100 decompresses the compressed update data downloaded for the target controller 2 122 having the previous version, generates difference data, and performs update. The management control device 110 of the vehicle 100 transmits compressed update data as it is to the target controller 3 (123) without a previous version to perform an update.

In this way, the management control device 110 can generate compressed data or differential data according to the download method of update data and whether or not there is downloaded data, thereby minimizing the update data to overcome the low in-vehicle communication speed.
