Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Over-the-air technology OTA upgrades on vehicles can generally be divided into OTA upgrades on single-run zone controllers and OTA upgrades on multi-run zone controllers.
As shown in FIG. 1, a single-run zone controller has only one run zone, while typically having one backup zone. Wherein, the upgrading and the running of the software are both in the running partition. When the software is upgraded, the software currently running in the running partition can be backed up to the backup partition, and if the upgrade fails, the software in the backup partition can be restored to the running partition.
As shown in fig. 2, the multi-partition controller includes multiple partitions, but only one partition is activated at a time, the other partitions are not activated, and the software is run in the activated partition and upgraded in the non-activated partition. When the upgrade is successful, switching the activation partition to the operation partition of the upgrade to realize the enablement of new software; and if the upgrading fails, not switching the activated partition.
Based on the two OTA upgrading principles, the invention optimizes the backup upgrading processes of the single-operation partition controller and the multi-operation partition controller in the OTA process, optimizes the OTA processes, and provides the OTA upgrading method and device of the over-the-air downloading technology, which can effectively shorten the OTA upgrading time of a user.
The method and apparatus for upgrading over the air technology OTA of the present invention will be specifically described with reference to the accompanying drawings.
FIG. 3 is a flowchart illustrating an over-the-air technology OTA upgrading method according to an embodiment of the present invention; as shown in fig. 3, an over-the-air technology OTA upgrading method includes the following steps:
s301, an over-the-air technology OTA upgrade package is obtained.
In this step, the OTA server receives the software of the latest version uploaded by the developer and applied to the controller, sends an OTA upgrade request to the OTA device after receiving the file of the latest version, and the OTA device acquires the software of the latest version from the OTA server according to the OTA upgrade request, namely, the OTA upgrade package of the over-the-air download technology OTA.
S302, the controller to be upgraded is pre-upgraded, and the user is informed that OTA upgrade can be carried out.
In this step, the controller that needs software upgrade, whether it is a single-operation partition controller or a multi-operation partition controller, performs pre-upgrade work, that is, preparation work for subsequent formal upgrade, and after completing the preparation work, notifies the user that the upgrade preparation work has been completed, and may perform formal OTA upgrade. Specifically, the completion of the pre-upgrading work of the user is prompted on the automobile display screen through the HMI, and the user can perform subsequent formal upgrading. The specific pre-upgrade process is different for different controllers, and the pre-upgrade process for different controllers is described below.
And S303, upgrading the currently running software by using an upgrading package of the OTA on the pre-upgraded controller according to the received instruction for determining the OTA upgrading by the user.
In this step, the user may perform OTA upgrade according to his own needs after seeing the notification in S102, and after receiving the instruction for the user to determine OTA upgrade, the OTA device upgrades the software currently running on the controller on the basis of completing the pre-upgrade work. The specific upgrading process is different according to different controllers, and the upgrading process of different controllers is described in the following.
The method for upgrading the OTA in the over-the-air technology provided by the embodiment of the invention upgrades the controller to be upgraded in advance, and upgrades the currently running software by using the controller after the upgrade is performed in advance after the received user determines the OTA upgrade instruction, thereby completing the whole OTA upgrade. Before the user selects formal upgrading, the preparation work is completed in advance, so that the formal upgrading time is shortened, the formal upgrading process is optimized, the OTA upgrading experience of the user is improved, and the problem that the user cannot normally use the OTA in the driving process due to the fact that the OTA needs too long time to be upgraded is solved.
Further, the controller to be upgraded is a single-operation partition controller, and the single-operation partition controller comprises an operation partition and a backup partition.
Correspondingly, the pre-upgrading of the controller to be upgraded comprises the following steps:
and pre-backing up the currently running software in the running partition into the backup partition so as to finish pre-upgrading.
In this embodiment, the pre-upgrade performed on the single-operation partition controller is that after receiving the OTA upgrade package of the latest version and before the user determines the formal software upgrade, the upgrade Master (i.e., OTA Master) backs up the currently-operating software in the operation partition to the backup partition in advance, instead of backing up the currently-operating software to the partition after the user issues the OTA upgrade instruction.
The upgrading of the currently running software by using the upgrading packet of the over-the-air technology OTA on the pre-upgraded controller comprises the following steps:
and upgrading the currently running software in the running partition by using the upgrading packet of the OTA.
In this embodiment, if an instruction for determining the formal upgrade by the user is received, the upgrade master control directly upgrades the currently running software in the running partition without backing up the currently running software in the formal upgrade process, and then upgrades the currently running software in the running partition according to the upgrade package of the over-the-air technology OTA, so that the time for the formal OTA upgrade is greatly shortened, and the user experience is improved.
According to the method for upgrading the OTA in the air download technology, provided by the embodiment of the invention, aiming at a single-operation partition controller, after receiving an OTA upgrade package of a latest version and before a user determines formal software upgrade, the software currently operated in an operation partition is backed up to a backup partition in advance; when receiving an OTA formal upgrade instruction, the software currently running in the running partition is upgraded directly according to the OTA upgrade package, so that the backup time of the currently running software after the OTA upgrade is started by a user is saved, and the user experience is improved.
FIG. 4 is a flowchart illustrating a single-run partition controller OTA upgrade method according to an embodiment of the present invention; as shown in fig. 4, after the software currently running in the running partition is upgraded by using the upgrade package of the over-the-air technology OTA, the method includes:
and under the condition that the currently-operated software fails to be upgraded, restoring the software which fails to be upgraded in the operating partition by using the currently-operated software which is backed up in the backup partition in advance.
In this embodiment, if the currently running software in the running partition fails to be upgraded, the software backed up in the backup partition is rolled back to the running partition in advance, and the running partition still runs normally with the previous software, so as to ensure the normal running of the single-running partition controller.
In addition, in the software backup process, the backup result is recorded through a mark bit which can show whether the backup is successful or not; in the formal upgrading process, whether the backup of the current software needs to be skipped is determined according to the mark bit, and the software in the running partition is directly upgraded. If the mark bit shows that the backup is not successful, the currently running software needs to be backed up in the formal upgrading process. And if the mark bit shows that the backup is successful, directly skipping the backup in the formal upgrading process, and upgrading the currently running software according to the OTA upgrading packet.
The upgrading method of the OTA provided by the embodiment of the invention can directly utilize the software which is pre-backed up in the backup partition in the pre-upgrading process under the condition that the upgrading of the currently running software fails, thereby ensuring the normal running of the controller.
Fig. 5 is a schematic flowchart of a method for upgrading a multi-partition controller OTA according to an embodiment of the present invention, and as shown in fig. 5, in another embodiment of the present invention, the controller to be upgraded is a multi-partition controller, and the multi-partition controller includes a running partition in an active state and a running partition in an inactive state.
The running partition in the activated state is the running partition in which the current software runs, and the running partition in the inactivated state is the running partition in which the software waits for upgrading.
Correspondingly, the pre-upgrading of the controller to be upgraded comprises the following steps:
and upgrading the software in the running partition in the inactivated state according to the upgrading packet of the OTA to finish pre-upgrading.
In this embodiment, if the controller to be upgraded is a multi-operation partition controller, the pre-upgrade operation is to upgrade software in an inactive operation partition according to the received OTA upgrade package of the latest version after receiving the OTA upgrade package of the latest version and before the user determines the formal software upgrade, so that the software in the inactive operation partition becomes the latest version.
It should be noted that the pre-upgrade process is automatically performed after the OTA upgrade package is acquired, and the user is notified of the formal upgrade after the pre-upgrade is completed, instead of starting after the user issues the formal upgrade instruction.
The method for upgrading the software running at present by using the over-the-air technology OTA upgrading packet on the pre-upgraded controller comprises the following steps:
and switching the activated state corresponding to the running partition where the currently running software is located into the inactivated state, and switching the inactivated state corresponding to the running partition where the upgraded software is located into the activated state to complete the upgrade.
In this embodiment, since the pre-upgrade work has already upgraded the software in an operating partition in an inactive state, after receiving a formal upgrade instruction issued by a user, the software in the operating partition in the inactive state does not need to be upgraded, and only the operating partition state corresponding to the software having the latest version is converted from the inactive state to the active state, and the operating partition state where the original software is located is converted from the active state to the inactive state, so that the software runs in the latest state.
According to the method for upgrading the OTA in the air download technology, provided by the embodiment of the invention, aiming at a multi-operation partition controller, after receiving an OTA upgrade package of the latest version and before a user determines formal software upgrade, software in an operation partition in an inactivated state is upgraded in advance; when receiving an OTA formal upgrade instruction, the state of the operation partition is directly adjusted to complete formal upgrade, thereby greatly saving the software upgrade time of a user after starting OTA upgrade and improving the user experience.
Further, after the upgrading the software in the running partition in the inactive state according to the upgrade package of the over-the-air technology OTA, the method further comprises:
and in the case of failure of software upgrading in the running partition in the inactivated state, continuing running with the currently running software in the running partition in the activated state.
In this embodiment, if the software in the running partition in the inactive state fails to be upgraded in the pre-upgrade process, the current running software continues to run, and the state of the running partition is not switched.
It should be noted that the software upgrade result in the running partition in the inactive state is recorded by the flag bit, and when the official OTA is upgraded, whether the software upgrade in the running partition in the inactive state is successful is determined by the flag bit. And if the mark bit shows that the software in the running partition in the inactivated state is successfully upgraded, directly switching the state of the running partition in which the software of the latest version is located in the formal OTA upgrading process, thereby completing the OTA upgrading. If the flag bit shows that the software in the running partition in the inactivated state is not successfully upgraded, the software in the running partition in the inactivated state needs to be tried to be upgraded again in the formal OTA upgrading process.
According to the over-the-air technology OTA upgrading method provided by the embodiment of the invention, under the condition that the software in the running partition in the non-activated state fails to be upgraded, the currently running software in the running partition in the activated state continues to run, so that the normal running of the controller is ensured.
In addition, no matter the controller runs in a single mode or runs in multiple modes, the result after formal upgrading can be displayed to the user through the HMI, and the user can know whether the software running currently is the latest version.
The upgrading device of the over-the-air technology OTA provided by the invention is described below, and the upgrading device of the over-the-air technology OTA described below and the upgrading method of the over-the-air technology OTA described above can be referred to correspondingly.
