The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all, of the embodiments of the present application.
The invention provides a vehicle OTA upgrading method. Fig. 1 shows a schematic flow chart of a vehicle OTA upgrade method 100 according to one embodiment of the invention. As shown in fig. 1, the method 100 may include the following steps.
Step S110, upgrade task information issued by the cloud is received, wherein the upgrade task information comprises an upgrade sequence, an upgrade mode, an upgrade strategy and a corresponding software package to be downloaded of the electronic control unit.
For example, the upgrade order of the electronic control units may be determined according to the dependency relationship between the upgrade packages of the electronic control units, which is not additionally limited herein. The software package obtaining manner may specifically be obtained by the vehicle to be upgraded from the link address according to the electronic control unit identifier, which is not limited herein. Specifically, whether the electronic control units at the vehicle end need to execute upgrading actions or not can be judged by comparing whether the current version of the electronic control units at the vehicle end is consistent with the target version of the cloud electronic control unit, and whether software packages of the corresponding electronic control units need to be downloaded or not is further judged. And receiving an upgrade task issued by the cloud under the condition that the current version of at least one electronic control unit at the vehicle end is inconsistent with the task version in the upgrade task information issued by the cloud, wherein the upgrade task information comprises an upgrade sequence, an upgrade mode, an upgrade strategy and a corresponding software package to be downloaded of the electronic control unit. Specifically, the intervals may be within a preset time, for example: the download conditions of the electronic control unit package were checked within 1 minute.
Step S120, based on the upgrade task information, sequentially upgrading each electronic control unit meeting the upgrade condition until the last electronic control unit in the electronic control units to be upgraded in the upgrade task is upgraded.
For example, the upgrade condition may be a difference between a current version of each electronic control unit at the vehicle end and a target version of the cloud electronic control unit. Specifically, under the condition that the current version of the vehicle-end electronic control unit and the target version of the cloud electronic control unit are different, the electronic control unit is judged to be the electronic control unit to be upgraded which meets the upgrading conditions. The difference between the current version of each electronic control unit and the target version of the cloud electronic control unit may be a quantity difference, and is not specifically limited herein.
After each electronic control unit is successfully upgraded in step S120, step S130 is executed: and judging whether the current updated electronic control unit is the last electronic control unit in the updating task. In the case that it is determined that the currently upgraded electronic control unit is the last electronic control unit, step S160 is executed to end the upgrade task. Otherwise, if the current updated electronic control unit is not the last electronic control unit in the updating task, the subsequent electronic control units are continuously updated in sequence until the last electronic control unit in the updating task is updated, and then the updating task is ended.
In the process of upgrading the electronic control unit, there may be an upgrade failure or an un-upgraded electronic control unit that cannot be upgraded because the upgrade condition is not satisfied. For such electronic control units, step S140 is performed to determine, for an un-upgraded electronic control unit that fails to upgrade or does not meet the upgrade condition, whether the current un-upgraded electronic control unit is a high-risk electronic control unit.
In particular, the high-risk electronic control unit may be an electronic control unit that affects the anchoring of the vehicle or the starting or closing of the vehicle. If the current un-upgraded electronic control unit is a high-risk electronic control unit, step S160 is executed to end the upgrade task. Otherwise, if the current non-upgraded electronic control unit is not the high-risk electronic control unit, step S150 is executed to determine whether the current non-upgraded electronic control unit is the last electronic control unit in the upgrade task. If yes, step S160 is executed to end the upgrade task. Otherwise, if the current un-upgraded electronic control unit is not the last electronic control unit in the upgrade task, step S140 is executed again to determine whether the next un-upgraded electronic control unit is a high-risk electronic control unit again based on the upgrade order, and the above steps are repeated until the upgrade task is completed.
According to the vehicle OTA upgrading method, upgrading task information issued by a cloud is received, wherein the upgrading task information comprises an upgrading sequence, an upgrading mode, an upgrading strategy and a corresponding software package to be downloaded of an electronic control unit; based on the upgrade task information, sequentially upgrading each electronic control unit meeting the upgrade condition until the last electronic control unit in the electronic control units to be upgraded in the upgrade task is upgraded; for the un-upgraded electronic control units which fail to upgrade or do not meet the upgrade conditions, judging whether the un-upgraded electronic control units are high-risk electronic control units, if so, ending the upgrade task, if not, judging whether the un-upgraded electronic control units are the last electronic control units in the upgrade task, and if not, ending the upgrade task, and if so, judging whether the next un-upgraded electronic control unit is the high-risk electronic control unit again based on the upgrade sequence until the upgrade task is ended, thereby realizing multiple special screening judgment on the electronic control units which fail to upgrade in the upgrade process of the electronic control units, upgrading each electronic control unit as much as possible, improving the upgrade efficiency and upgrade completion rate of the electronic control units, and improving the user experience.
Optionally, the method further comprises: uploading upgrade failure information corresponding to the un-upgraded electronic control unit to the cloud end so as to update the upgrade record by the cloud end.
Illustratively, the upgrade failure information may include: all present and future information which can distinguish the non-upgraded electronic control unit from other electronic control units in the whole vehicle, including version information, function information, name information, risk degree information and the like of the non-upgraded electronic control unit, is not limited in any way. Preferably, when the current non-upgraded electronic control unit is a high-risk electronic control unit, the electronic control unit can be marked, and when the whole vehicle electronic control unit is upgraded again, the high-risk electronic control unit can be skipped directly, so that the upgrading operation of the whole vehicle electronic control unit can be completed rapidly. According to the method, the upgrading failure information corresponding to the un-upgraded electronic control unit is uploaded to the cloud end, so that the cloud end updates the upgrading record, the upgrading condition of the whole vehicle electronic control unit and the version information of the current electronic control unit of the whole vehicle are controlled and recorded in real time, and convenience is brought to the future re-upgrading of the electronic control unit of the whole vehicle.
Optionally, the method further comprises: and judging whether the electronic control unit which is not upgraded meets the upgrading conditions again, if so, skipping over the current electronic control unit which is not upgraded, upgrading the next electronic control unit based on the upgrading sequence, and if not, ending the upgrading task.
For example, in the case that the non-updated electronic control unit satisfies the update condition, that is, in the case that the version of the non-updated electronic control unit differs from the target version and the non-updated electronic control unit is not the high-risk electronic control unit or the last electronic control unit to be updated, skipping the current non-updated electronic control unit, and updating the next electronic control unit based on the update sequence; and ending the upgrading task under the condition that the non-upgrading electronic control unit does not meet the upgrading condition, namely that the version of the non-upgrading electronic control unit is not different from the target version. According to the method, whether the electronic control unit which is not upgraded meets the upgrading conditions is judged secondarily, so that the electronic control unit which is failed to upgrade is screened for multiple times in the upgrading process of the electronic control unit, and the upgrading completion rate of the electronic control unit is improved.
Fig. 2 shows a schematic flow chart of a vehicle OTA upgrade method according to another embodiment of the invention.
As shown in fig. 2, after the upgrade task is completed, the method 100 may further include the steps of:
step S170, the upgrade task information is returned to the cloud end so that the cloud end updates the upgrade record, wherein the upgrade task information comprises upgrade success information of the electronic control unit and upgrade failure information of the electronic control unit.
Illustratively, the electronic control unit upgrade success information may include: latest version information, function information, name information, upgrade completion time-consuming information and the like of the electronic control unit for which upgrade has been completed; the electronic control unit upgrade failure information may include: current version information, function information, name information, upgrade failure cause information, and the like of the electronic control unit that fails in upgrade. According to the method, the cloud end is returned with the upgrade task information so that the cloud end can update the upgrade record, wherein the upgrade task information comprises the upgrade success information of the electronic control unit and the upgrade failure information of the electronic control unit, so that the upgrade condition of the upgrade of the electronic control unit of the whole vehicle is accurately controlled, a foundation is laid for upgrading the electronic control unit of the whole vehicle again, and further the operation steps and time of the subsequent upgrade process of the electronic control unit of the whole vehicle are saved.
Step S180, deleting the software package corresponding to the electronic control unit which is successfully upgraded based on the upgrade task information, and storing the software package corresponding to the electronic control unit which is failed to upgrade.
For example, the vehicle-end component may delete the software package corresponding to the electronic control unit that is successfully upgraded currently based on the upgrade task information, and store the electronic control unit software package that fails to upgrade in the storage area. According to the method, the software package corresponding to the electronic control unit which is successfully upgraded is deleted based on the upgrading task information, the software package corresponding to the electronic control unit which is failed to upgrade is stored, the storage space of the whole vehicle is saved, meanwhile, material conditions are provided for upgrading the electronic control unit which is failed to upgrade again, and time and steps for upgrading the electronic control unit again are saved.
Optionally, the upgrade condition includes that the current software version of the at least one electronic control unit is inconsistent with the target version of the cloud deployment.
Specifically, when the current version of at least one electronic control unit at the vehicle end is inconsistent with the task version in the upgrade task information issued by the cloud end, the upgrade task issued by the cloud end is received. According to the method, the upgrading state of the electronic control unit is judged through comparison of the cloud version information, so that the downloading time of the software package of the electronic control unit which is not upgraded is shortened, the loss of flow is reduced, and the upgrading time of the electronic control unit of the whole vehicle is saved.
Optionally, the method further comprises: under the condition that the upgrading condition is met, downloading the software package from the cloud; in the downloading process, if the vehicle end is disconnected with the content distribution network, the vehicle end automatically records the downloading breakpoint of the software package so as to continue to download the software package from the breakpoint after the downloading condition is met again.
For example, in the case that the upgrade condition is satisfied, the vehicle end may request to download the software package of the electronic control unit from the content distribution network, and store the software package in the OTA cache area in the TBOX. In the downloading process, if the content distribution network of the vehicle is disconnected due to the occurrence of power-down or other abnormal conditions, the vehicle end component can automatically record the latest breakpoint of the software package downloading, and after the vehicle meets the downloading condition again, the software package can be continuously downloaded according to the recorded power-down of the vehicle end component. According to the method, under the condition that the upgrading condition is met, the software package is downloaded from the cloud; in the downloading process, if the vehicle end is disconnected with the content distribution network, the vehicle end automatically records the downloading breakpoint of the software package so as to continue to download the software package from the breakpoint after the downloading condition is met again, thereby realizing breakpoint continuous transmission of the software package of the electronic control unit, avoiding the situation of restarting downloading the software package due to sudden network interruption in the downloading process, and reducing the loss of flow.
Optionally, after the software package is downloaded, the method further includes: and (3) performing signature verification operation on the software package, starting upgrading operation of the electronic control unit if the signature verification is passed, and re-downloading a new software package if the signature verification is failed.
For example, whether the software package of the target version is stored in the vehicle storage space can be judged according to the software version cache information of the electronic control unit reported by the vehicle side. If yes, the software package is subjected to signature verification operation, if the signature verification is passed, the electronic control unit upgrading operation is started, and if the signature verification is failed, the new software package is downloaded again. Preferably, if there is no target version package in the vehicle storage space, it may be marked for download. According to the method, the situation that the upgrade of the electronic control unit fails due to the fact that the file software package is tampered or the software package is damaged is avoided through the verification of the software package, and the upgrade efficiency of the electronic control unit and the upgrade experience of a user are improved.
