Technical Field

The present invention relates to the field of vehicle control, and in particular, to a vehicle application updating method, a device, a storage medium, and an electronic device.

Background

With The development of intelligent automobiles, remote upgrade (OTA) has become one of The necessary functions of intelligent automobiles. However, in the OTA upgrading process, the failure of the controller upgrade can cause the vehicle to fail to operate normally, so that it is required to ensure that the last version of software can be refreshed, and the controller is prevented from changing bricks.

Currently, the main scheme is to reserve a software package of a previous version in a vehicle control system, and when the update of the new version fails, the software package of the previous version can be rolled back. However, rollback errors are prone to occur using the above approach, resulting in application update failures. Therefore, it is necessary to provide the AB system in the controller. Most chips do not support AB system functionality. And, if a main chip with an AB system function is selected, the cost of the controller increases.

In view of the above problems, no effective solution has been proposed at present.

FIG. 1 is a flow chart of a vehicle application update method according to one embodiment of the invention, the method being applied to a vehicle controller system, the vehicle controller system comprising: a first memory for storing boot load content and primary application content, and a second memory for storing backup application content, as shown in fig. 1, the method comprising the steps of:

Step S10, acquiring download identification information, wherein the download identification information is used for determining a target download mode, and the target download mode is used for downloading application update contents for a vehicle controller system;

in the above step S10, the downloaded identification information includes information such as a diagnostic apparatus identification number (Identity, ID) or an OTA ID. And if the download identification information is different, the target download modes are different. The above-mentioned goal download mode includes using the diagnostic apparatus of the off-line to download the application and upgrade the content for vehicle controller system, on-line OTA downloads the application and upgrade the content for vehicle controller system, wherein, the diagnostic apparatus mode of the off-line means to use diagnostic apparatus to control vehicle application and upgrade, diagnostic apparatus and controller carry on the wired connection, on-line OTA means to upgrade and upgrade software and firmware controlling the vehicle through the wireless communication technology.

Specifically, the associated information of each downloading device may be stored in advance in the controller, where the associated information includes information such as an identity identifier and a type of the downloading device that has been registered by the vehicle, and the identity identifier specifically includes information about an identity unique identifier number of the downloading device. Thus, the download identification information is acquired, and the target download method can be determined. For example, if the acquired download identification information ID is 001, and the type of the download device corresponding to 001 is diagnostic apparatus by comparing 001 with the download device information stored in advance, it is determined that the vehicle application update is controlled by using the diagnostic apparatus.

Step S12, determining a target update object in the vehicle control system based on the download identification information, wherein the target update object is obtained by selecting from the main application content and the backup application content;

in the step S12, the target update object is determined based on a target download method, and the target download method is different and the target update object is different.

Step S14, updating the target update object by using the boot loading content and the application update content.

Specifically, fig. 2 is a schematic diagram of a vehicle application updating method according to an embodiment of the present invention, and as shown in fig. 2, a vehicle controller system includes a first Memory and a second Memory, where the first Memory refers to a non-AB main chip, and the second Memory refers to an external electrically erasable programmable read-Only Memory (External Electrically Erasable Programmable Read-Only Memory). The main chip is divided into two areas, namely a boot loading content area and an A area, wherein the boot loading content area is mainly used for storing boot application software, such as BootLoader software, and the BootLoader software is mainly used for starting the boot application software and updating the application software; the A area is mainly used for storing main application content, and updating the main application content in the A area when online OTA is used for updating; the second memory is divided into a B area and is mainly used for storing backup application content, where the backup application content is the same as the main application content or is the last version of the main application content, and the invention is not limited to this.

Further, first, the boot application software in the boot loader content area, i.e., bootLoader software, is invoked. The BootLoader software will initiate a download device authentication interface, which is typically used to authenticate the validity of the download device and ensure that only authorized devices can access the download device, and the download device will send an access request to the BootLoader software requesting access to the controller for data transmission or other operations. The BootLoader software can perform security verification on the access request of the downloading device so as to ensure the legality and security of the downloading device. Then, a target downloading mode is determined based on the downloading identification information, wherein the target downloading mode comprises the steps of downloading application updating content for a vehicle controller system by using an online diagnostic apparatus and downloading application updating content for the vehicle controller system by using an online OTA, so as to determine a target updating object in the vehicle control system. And finally, updating the target update object by using the boot loading content and the application update content.

It should be noted that the memory space of the EEPROM needs to be larger than the memory space occupied by the application content, and the technical effect of ensuring the sufficient memory space when the memory realizes the AB system is realized by the mode of combining the non-AB main chip and the EEPROM.

Based on the steps S10 to S14, the method of acquiring the download identification information and determining the target update object in the vehicle control system based on the download identification information is adopted, and the target update object is updated by using the boot loading content and the application update content, so that the purpose of rapidly updating the vehicle application is achieved, the technical effect of improving the update efficiency of the vehicle application is achieved, and the technical problem of low update efficiency caused by the update of the vehicle application based on the non-AB chip in the related art is further solved.

Optionally, in step S12, determining the target update object in the vehicle control system based on the download identification information includes:

step S121, in response to determining that the target download mode is the first download mode based on the download identification information, determining the main application content and the backup application content as target update objects;

in step S121, the first downloading method is to update the vehicle application by using the diagnostic apparatus.

Specifically, if it is determined that the offline diagnostic apparatus is used to download the application update content based On the download identification information, the main application content in the a area and the backup application content in the B area are updated simultaneously based On the running of Bootloader software, and are used before the controller gets On the vehicle or when the application program is updated through an On-board diagnostic (On-Board Diagnostics, OBD) interface, so that the simultaneous existence of the main program content and the backup program content in the controller is ensured.

Step S122, in response to determining that the target download mode is the second download mode based on the download identification information, determining the main application content as the target update object.

In step S121, the first downloading method refers to updating the vehicle application by the OTA.

Specifically, if it is determined that the OTA download application is used to update the content based on the download identification information, the running of the Bootloader software only updates the main application content in the a area in the first memory.

Based on the steps S121 to S122, determining the main application content and the backup application content as target update objects in response to determining that the target download mode is the first download mode based on the download identification information; in response to determining that the target downloading mode is the second downloading mode based on the downloading identification information, determining the main application content as a target updating object, using the first downloading mode can ensure that the vehicle control system cannot work normally due to unexpected faults in the updating process, using the second downloading mode can ensure updating of the main application content, meanwhile, reducing updating frequency of backup application content, reducing maintenance cost and updating time of the vehicle control system, and two different downloading modes can improve flexibility and reliability of the vehicle control system.

Optionally, the vehicle application updating method further includes:

step S15, in response to the completion of updating the target updating object, validity judgment is carried out on the main application content, and a first judgment result is obtained;

step S16, determining target execution content of the vehicle control system based on the first judgment result.

Specifically, when the target update object completes the update, it is determined whether the main application content in the first memory a area is valid.

Further, the boot application software is invoked from the boot load content area of the host chip; and judging whether the main application content exists in the A area of the main chip by executing the guiding application software, if so, determining that the main application content in the A area is valid, otherwise, determining that the main application content in the A area is invalid. For example, bootloader software is called from a boot loading content area of the main chip, whether main application content in the area a is valid is judged by executing the Bootloader software, if the main application is determined to be valid in the area a, the application in the area a is determined to be valid, the target application sent by the diagnostic apparatus or the OTA device is described, the target application is adopted to update the application in the area a, otherwise, the main application content in the area a is determined to be invalid.

Based on the steps S15 to S16, in response to the completion of updating the target updating object, performing validity judgment on the main application content to obtain a first judgment result; and determining target execution content of the vehicle control system based on the first judgment result, wherein the validity judgment can ensure that the vehicle control system operates the latest and valid main application content, thereby improving the safety of the vehicle control system.

Optionally, in step S16, determining the target execution content of the vehicle control system based on the first determination result includes:

step S161, in response to determining that the main application content is valid based on the first judgment result, determining the main application content as target execution content;

in step S161, if the main application content in the a area of the main chip is valid, the main application content is determined as the target execution content, and the main application content is executed.

Step S162, in response to determining that the main application content is invalid based on the first judgment result, performing validity judgment on the backup application content to obtain a second judgment result;

in the step S162, if the main application content in the area a is invalid, it is determined whether the backup application content in the area B is valid, so as to obtain a second determination result.

Specifically, when the validity of the main application content in the area a is determined to be invalid, it is indicated that the diagnostic apparatus or the OTA device fails to update the area a, and at this time, it needs to determine whether the backup application in the area B is valid.

Step S163, determining the target execution content based on the second determination result.

In the step S163, the second determination result is the validity and invalidity of the backup application in the B area, and if the determination results are different, the target execution content is different.

Based on the above steps S161 to S163, in response to determining that the main application content is valid based on the first determination result, the main application content is determined as the target execution content; responding to the fact that the main application content is invalid based on the first judging result, and judging the validity of the backup application content to obtain a second judging result; and determining target execution content based on the second judgment result, and ensuring that the vehicle control system can switch to the backup application content in time under the condition that the main application content is invalid, thereby improving the reliability and stability of the vehicle control system.

Optionally, in step S163, determining the target execution content based on the second determination result includes:

step S1631, in response to determining that the backup application content is valid based on the second determination result, updating the main application content by using the backup application content to obtain an update result;

Step S1632, the update result is determined as the target execution content.

Specifically, when the second judgment result determines that the backup application content in the area B is valid, acquiring the valid backup application content contained in the area B, rolling back the backup application content to the area a, replacing the original main application content, and jumping to the area a to execute the replaced main application content.

Further, when the second judging result determines that the backup application content in the area B is invalid, it is determined that the current main chip does not acquire the application from the downloading device for updating, and the boot application software in the boot loading content area is kept in a state of waiting for receiving information.

Based on the steps S1631 to S1632, in response to determining that the backup application content is valid based on the second determination result, updating the main application content by using the backup application content to obtain an update result; and determining the updating result as target execution content, ensuring that the updating of the main application content is based on effective backup content, and improving the reliability and stability of the vehicle control system.

Optionally, the vehicle application updating method further includes:

step S17, responding to the power-down processing of the vehicle controller system, and acquiring the first version information of the main application content and the second version information of the backup application content;

In step S18, the primary application content and the backup application content are version-synchronized using the first version information and the second version information.

Specifically, when the power-down processing is performed on the vehicle control system, version information of the main application content in the area a and version information of the backup application content in the area B are acquired. Version synchronization is performed based on version information of the primary application content and version information of the backup application content.

Based on the steps S17 to S18, in response to performing the power-down process on the vehicle controller system, obtaining the first version information of the main application content and the second version information of the backup application content; and carrying out version synchronization on the main application content and the backup application content by utilizing the first version information and the second version information, so that the data consistency between the main application content and the backup application content is ensured, and the data consistency, the safety, the fault recovery capability and the stability of the vehicle control system can be improved, thereby ensuring the normal operation and the data integrity of the vehicle control system.

Optionally, in step S18, performing version synchronization on the primary application content and the backup application content using the first version information and the second version information includes:

in step S181, the backup application content is updated with the primary application content in response to the first version information and the second version information being inconsistent.

Specifically, when the version information content of the main application content is not used for the version information of the backup application content, the main application content is updated into the backup application content.

It should be noted that, after the online OTA is used for application update, the version of the main application content in the a area is higher than the version of the backup application content in the B area, so as to achieve the synchronization of the application contents in the a area and the B area.

Based on the step S181, in response to the inconsistency of the first version information and the second version information, the backup application content is updated by using the main application content, so as to ensure that the backup application is consistent with the main application, reduce the risk of losing or damaging the main application content and/or the backup application content, and simultaneously ensure that the main application content and/or the backup application content can be recovered more quickly when a failure or when the application content occurs.
