Description

Technical Field

[0001] The present invention relates to the field of automobile software technology, and in particular to an online-based automobile OTA software reset method. Background Art

[0002] With the development of intelligent connected cars, OTA capabilities have gradually become standard for cars, and it has become a trend for car manufacturers to solve car software problems and product iterations through OTA. On the other hand, due to the intensification of competition and the existence of OTA, the R&D cycle of new models has been continuously compressed, from the original 3 to 4 years to 1 to 2 years or even shorter, which is a major challenge to product quality.

[0003] As automotive software, OTA also has common software problems: there are undiscovered bugs. Combined with such a short vehicle development cycle, stability is inevitably compromised, and some unexpected problems occur during operation. OTA software consists of a cloud-based Web management platform and OTA components on the vehicle side. Problems with OTA cloud can be solved by redeployment, which has little impact on car manufacturers and consumers; however, when problems occur with OTA vehicle-side components, especially problems of falling into an endless loop and infinite software restarts, the impact may be catastrophic and can only be solved through offline recalls, which increases costs and reduces consumers' trust in the brand.

[0004] In order to solve the above problems, this application proposes a method for resetting automobile OTA software based on online mode. Summary of the invention

[0005] In response to the problems in the related technology, the present invention provides a method for resetting automobile OTA software based on an online method, which can effectively solve the problem of OTA function being unusable due to problems with the OTA software itself, significantly reduce the cost of solving such problems, and enhance consumers' trust in the brand.

[0006] To this end, the specific technical solution adopted by the present invention is as follows: A method for resetting automobile OTA software based on online mode includes an OTA management platform, a TSP platform, a TSP client, an OTA Master, an OTA Sub Master and an HMI. The OTA management platform interacts with the TSP platform through an API to actively send instructions from the cloud to the vehicle. In the OTA scenario, the TSP platform is mainly used to push information from the cloud to a designated vehicle. The TSP client is a TSP component in the car and is used to receive push instructions from the TSP platform. The OTA Master interacts with the car owner by interacting with the HMI module. The OTA Sub Master is used to receive the scheduling of the OTA Master and is responsible for the execution of specific functions, such as flashing a certain part.

[0007] As a further solution of the present invention, the OTA management platform is responsible for the management of vehicle information, parts information, and software package information; is responsible for the creation, release, and destruction of OTA tasks; is responsible for the statistics and display of data related to OTA tasks, interacts with OTA operators through a web browser, and provides a series of APIs to interact with vehicle-side OTA components.

[0008] As a further solution of the present invention, the OTA Master is a car-side OTA main control module, which is responsible for realizing vehicle-cloud business interaction through the API exposed by the OTA management platform, and is also used for car-side OTA business status management.

[0009] As a further solution of the present invention, the OTA Master process control realizes the OTA function by interacting with the TSP client and each OTASub Master to control the timing.

[0010] As a further solution of the present invention, the HMI human-computer interaction module is used to respond to the vehicle owner's operating instructions and display the upgrade process information.

[0011] As a further solution of the present invention, when the OTA management platform issues a Reset instruction, the following steps are specifically included: S1: When importing a single vehicle, enter the VIN of the vehicle that needs to be reset. When importing in batches, write the VIN of the vehicle that needs to be reset into Excel according to the specified template, upload the Excel to the OTA management platform, and import the vehicle VIN in batches; S2: Select the model that needs to be reset. The OTA management platform selects all vehicles under this model by default. S3: Select the OTA task. The OTA management platform selects the vehicle involved in the task by default. S4: After the vehicle range is selected, the OTA operator clicks the "Reset" button to call the Reset API provided by the TSP platform, and passes the Reset command to the TSP platform with the vehicle VIN list as the parameter. The TSP platform then traverses the vehicle VIN list and pushes the Reset command (generally through the MQTT protocol) to the specified vehicle. After the vehicle-side TSP client receives the push command, it responds to the TSP platform. The TSP platform synchronizes the push results to the OTA platform. Finally, the TSP client sends the Reset command to the OTA Master, and the OTA Master executes the Reset operation and directly feeds back the results to the OTA management platform.

[0012] As a further solution of the present invention, the vehicle-side Reset operation specifically includes the following steps: S1: The TSP client receives the Reset command and synchronizes the Reset command to the OTA Master; S2: OTA Master distributes the Reset command to other OTA components; S3: All OTA components including OTA Master perform reset operation, reset content Including but not limited to: a) Terminate the current task; b) Delete downloaded data; c) Output local persistent storage data; d) Clear the memory cache; S4: The process is restarted. During this process, after the OTA Master component on the car side is started, a separate thread needs to be started to receive the Reset command and perform the Reset operation, which is separated from the main thread business to avoid the main thread being blocked or entering an infinite loop, and being unable to execute the Reset command after receiving it.

[0013] The beneficial effects of the present invention are: The present invention uses a backup mechanism for the OTA software on the vehicle side to solve the problem that the OTA component on the vehicle side cannot recover by itself. The OTA cloud sends instructions to the OTA component on the vehicle side, so as to reset the OTA component on the vehicle side to the initial state and ensure the availability of the OTA function. Therefore, the method can effectively solve the problem that the OTA function cannot be used due to problems with the OTA software itself, significantly reduce the cost of solving such problems, and enhance consumers' trust in the brand.
