The remote upgrade control method of fig. 2 may be performed by a user terminal, which may be implemented by the first terminal device or the second terminal device or the third terminal device of fig. 1. As shown in fig. 2, the remote upgrade control method includes:

It can be understood that, in this embodiment, the method is executed by the user terminal, the user terminal communicates with the cloud server through a wireless network connection, the cloud server communicates with Tbox connections of the target vehicle through a wireless network, the conventional cloud server is used for performing OTA remote upgrade on the target vehicle, by using the method of this embodiment, the cloud server feeds back the specific progress of the remote upgrade to the user terminal, and the user terminal displays relevant information on the display terminal based on the feedback of the cloud server, so that the user can check; further, the user can perform clicking operation on the display identifier on the display terminal, and after receiving the clicking operation, the user terminal sends an operation instruction to the cloud server, wherein the operation instruction is used for controlling the remote upgrading process of the cloud server to the target vehicle. Therefore, the user can sense the remote upgrading process in real time and control the remote upgrading process, and the remote upgrading experience is improved.
Specifically, the upgrade management state machine obtained and stored in this embodiment includes not only all cloud states, but also a skip relation between cloud states, where the skip relation includes front and back cloud states of each cloud state, and may further include skip conditions between cloud states, where the skip conditions include cloud server or target vehicle update, click operation trigger, and so on.
It can be understood that, the method of this embodiment is applied to a remote upgrade process, which mainly includes a downloading process and an installation process, and since the present embodiment aims at providing the user with the display and control of the remote upgrade progress, the whole process can be divided into a plurality of stages by further adding the content of the display interaction: the method comprises a current latest version stage, a new version discovery stage, a downloading stage, a stage to be installed and a stage in installation. The current latest version stage means that the corresponding target vehicle is in the latest version, and remote upgrading is not needed; the new version discovery stage means that the cloud server has an updated version and can upgrade the target vehicle, but the target vehicle does not download the upgrade file yet; the downloading stage means that the target vehicle is downloading the upgrade file; in the stage to be installed, the target vehicle finishes downloading the upgrade file and is not installed yet; the mid-installation stage means that the target vehicle is installing an upgrade file.
According to different stages in the remote upgrading process, the corresponding display interfaces have differences, and the selectable display interfaces in the embodiment have a first page, a new version information page and an installation information page, and the process of determining the corresponding display interfaces specifically based on the stage in which the current cloud state is located comprises the following steps:
if the current cloud state is in the current latest version stage, determining that the display interface is a home page;
If the current cloud state is in a new version discovery stage, a downloading stage or a stage to be installed, determining that the display interface is a new version information page;
and if the current cloud state is in the installation stage, determining the display interface as an installation information page.
It can be understood that the current latest version stage does not need to perform a downloading operation or an installation operation, so that the corresponding display interface is set as a first page for displaying display information of "the current latest version stage does not need to perform the downloading operation or the installation operation" to a user; the new version stage, the downloading stage or the stage to be installed are found to belong to the stage in which the new version exists but the installation of the new version of the upgrade file on the target vehicle is not started, so that the display interface is set as a new version information page and used for displaying display information of 'the new version exists currently but the installation of the new version of the upgrade file on the target vehicle is not started' to a user; when the new version of the upgrade file is started to be installed, namely in the installation stage, a display interface is set as an installation information page and used for displaying display information of 'the new version of the upgrade file is currently installed' to a user.
It can be understood that, because the display information to be displayed to the user is different, the layout and the specific display content of the home page, the new version information page and the installation information are different, in this embodiment, the display content is represented by a display identifier, where the display identifier is used to represent, on the one hand, the specific content of the current cloud state and, on the other hand, the next cloud state where the current cloud state can be jumped or is about to be jumped. If the jump is triggered by clicking operation, the display identifier also corresponds to clicking logic of the clicking operation, when a user clicks a certain display identifier, the user terminal in this embodiment receives the clicking operation about the display identifier, and further sends a corresponding operation instruction to the cloud server according to the clicking logic, for example, an instruction display text contained in the display identifier is "download upgrade file", when the clicking operation about the display identifier is received, the operation instruction generated according to the clicking logic is an immediate downloading instruction, the immediate downloading instruction is sent to the cloud server, and the cloud server executes an action of immediately downloading the upgrade file to the target vehicle.
Further, after the cloud server executes the operation instruction, the current cloud state will change, and the change needs to be synchronized to the user terminal, so that the step S202 is executed to update the state information, and the steps S203 to S205 are further executed to update the display interface and the display identifier.
Specifically, among all cloud states in the upgrade management state machine, the cloud states in the current latest version stage include: the new version state and the successful installation state are not detected;
Cloud states in the stage of discovering new versions include: detecting a new version state, a manual canceling downloading state and a downloading failure state;
Cloud states in the download phase include: a pause download state, a download in-progress state;
The cloud state at the stage to be installed includes: a successful downloading state, a state of waiting for the expected time to arrive, a manual canceling of the installation state, a failure state of checking the environment before installation, and a failure state of installation;
Cloud states at the mid-installation stage include: the pre-installation environment inspection in-process state, the pre-installation environment inspection success state, the pre-installation preparation in-process state, and the in-installation state.
It will be appreciated that the clicking operations above include immediate download instructions, pause download instructions, resume download instructions, cancel download instructions, immediate install instructions, reserve install instructions, cancel reserve instructions, confirm install instructions, cancel install instructions, and the skip relationship between the cloud states above may include:
The next cloud state in which no new version state is detected includes: the new version state is not detected or the new version state is detected;
the next cloud of successful installation states includes: the new version state is not detected;
Detecting a next cloud state of the new version state includes: a download in progress state triggered by an immediate download instruction;
the next cloud state of the artificial cancel download state includes: detecting a new version state;
the next cloud state of download failure states includes: detecting a new version state;
the next cloud state of the pause download state includes: the download in-process state triggered by the resume download instruction, the manual cancel download state triggered by the cancel download instruction;
The next cloud state of the in-download state includes: a pause downloading state triggered by a pause downloading instruction, a manual canceling downloading state triggered by a canceling downloading instruction, a downloading failure state and a downloading success state;
The next cloud state of the download success state includes: a pre-installation environment check in-progress state triggered by an immediate installation instruction, a waiting scheduled time arrival state triggered by a scheduled installation instruction;
waiting for the next cloud of expected time to arrive at the state includes: a pre-installation environment check in-progress state triggered after the arrival of the predicted time or triggered by an immediate installation instruction, a wait predicted time arrival state triggered by a reserved installation instruction, a download success state triggered by a cancel reserved instruction;
The next cloud of artificial cancellation of the installation state includes: a pre-installation environment check in-progress state triggered by an immediate installation instruction, a waiting scheduled time arrival state triggered by a scheduled installation instruction;
the next cloud state of the pre-installation environment inspection failure state includes: a pre-installation environment check in-progress state triggered by an immediate installation instruction, a waiting scheduled time arrival state triggered by a scheduled installation instruction;
The next cloud of installation failure states includes: a pre-installation environment check in-progress state triggered by an immediate installation instruction, a waiting scheduled time arrival state triggered by a scheduled installation instruction;
the next cloud of states in the pre-installation environmental check includes: a pre-installation environment check success state, a pre-installation environment check failure state;
The next cloud state of the pre-installation environment check success state includes: the pre-installation preparation state triggered by the confirmation installation instruction and the manual cancellation of the installation state triggered by the cancellation of the installation instruction;
The next cloud of states in preparation before installation includes: a mid-installation state;
the next cloud of states in the installation includes: a successful installation state and a failed installation state.
According to the above description of each cloud state and the relationship of the operation instruction triggering the cloud state, the same cloud state may have a plurality of jump objects, namely, the next cloud state, in the jump relationship of the cloud states, and the actual state update requires the combined action of the cloud server, the target vehicle and the clicking operation, that is, the next cloud state actually updated is the unique specific cloud state determined from a plurality of possible jump objects based on the combined action on the premise of the jump relationship.
Further, because the instruction triggering condition exists in the state change, the process of transferring and validating the information of the operation instruction from the user terminal to the cloud server and then to the target vehicle has time delay, in order to improve the interaction experience, the time delay process can also set the corresponding instruction state according to the clicking operation, set the display identifier to be in a form corresponding to the instruction state, and update the display identifier to be in a corresponding cloud state when the operation instruction is validated. Therefore, the upgrade management state machine further comprises a plurality of instruction states corresponding to each clicking operation one by one, and a jump relation exists between each instruction state and the corresponding cloud state;
when a clicking operation for any display identifier is received, the method further comprises the following steps:
and updating the display interface and the display identifier based on the instruction state corresponding to the clicking operation.
It may be understood that updating the display interface and the display identifier based on the instruction status of the clicking operation means that the response of the executing body of the embodiment to the clicking operation is fed back to the user, that is, the clicking operation has been received and the corresponding flow is being performed based on the clicking operation.
Further, when receiving a click operation for any display identifier, sending an operation instruction to the cloud server according to a corresponding click logic, so that the cloud server executes the operation instruction on the target vehicle, including:
sending an operation instruction to the cloud server according to the corresponding click logic, so that the cloud server executes the operation instruction on the target vehicle and updates the current state information based on the jump relation between the instruction state and the cloud state;
After the step of sending a status request to the cloud server to enable the cloud server to return current status information based on the status request is executed, the process of determining the corresponding display interface based on the stage in which the current cloud status is located includes:
And if the current cloud state in the current state information is the next cloud state of the current instruction state, determining a corresponding display interface based on the stage of the current cloud state.
It may be understood that in the embodiment where only the cloud state does not have the instruction state, when the clicking operation is received, a corresponding operation instruction is sent to the cloud server to enable the cloud server to execute the operation instruction on the target vehicle, and then the execution step S202 is returned to send a state request to the cloud server to enable the cloud server to return to the current state information based on the state request, where the purpose of returning to the execution step S202 is that if the cloud server executes the operation instruction on the target vehicle to cause the current cloud state to change, the whole set of procedures can be executed again from S202.
Further, when the instruction state is added in the jump relation, in order to ensure that the displayed state is accurate, a limiting condition that the current cloud state is the next cloud state corresponding to the current instruction state is added as a necessary basis for display updating of a subsequent display interface and a display identifier. This is to avoid the problem of state bounce caused by information delay or dyssynchrony, which is one of the following situations that may occur: when the cloud state returned by the cloud server is the original state, the display interface is jumped back to the display interface capable of executing the clicking operation from the display interface which has responded the clicking operation, and misunderstanding that the clicking operation is invalid is easily caused by a user.
Therefore, after the setting of the display interface based on the update of the instruction state is added, the embodiment further emphasizes the correct response and jump of the display interface to the instruction state, and the complete response process to the clicking operation includes: sending an operation instruction to the cloud server according to the corresponding click logic so that the cloud server executes the operation instruction on the target vehicle; step S202 is executed, a state request is sent to the cloud server, so that the cloud server returns current state information based on the state request; step S203 is executed, specifically including: if the current cloud state in the current state information is the next cloud state of the current instruction state, determining a corresponding display interface based on the stage of the current cloud state; steps S204 to S205 are performed. According to the process, the accuracy of the display interface can be ensured, and the problem of user experience caused by repeated rebound of the display interface is avoided.
Taking an operation instruction as an immediate downloading instruction as an example, the following processes are provided:
When a clicking operation of a display identifier of 'immediate downloading' is received, determining that the corresponding instruction state is in immediate downloading instruction transmission, and updating the display identifier based on the state, namely, the identification text of the display identifier is in immediate downloading instruction transmission, and simultaneously transmitting the immediate downloading instruction to a cloud server; the cloud server executes the action of immediately downloading the upgrade file to the target vehicle, and updates the internal current cloud state into a downloading state when the cloud server starts to execute the action of downloading the upgrade file;
Sending a state request to a cloud server to receive current state information returned by the cloud server;
If the cloud state in the received current state information is the expected next cloud state of the state in the process of sending the immediate downloading instruction, namely the downloading state, the cloud server can be determined to have received the current operation instruction and begin to execute, so that the actual state is the downloading state, and the display interface and the display identifier can be updated according to the received current cloud state;
if the cloud state in the received current state information is not the downloading state, the current cloud server still keeps the original display identification, namely the identification text of the display identification is in the process of sending the immediate downloading instruction, if the current operation instruction is not received or the operation instruction is not started to be executed.

Further, referring to the specific flow chart shown in fig. 4, the operation procedure of the embodiment of the present embodiment is as follows:
when detecting that an OTA new version exists in the OTA home page, comparing an OTA state attribute field of the returned data according to the server with an OTA state machine:
If the OTA is in the downloading stage, the lower view button can be clicked to enter an OTA new version information page, and the OTA update progress method of the OTA single-instance object is immediately called to start polling (an intermittent circulation request server is used for acquiring the downloading progress) until the OTA downloading is completed, and then the polling is ended and the circulation is jumped out.
If the OTA is in the 'to-be-installed stage', the lower 'upgrading' button can be clicked to enter an OTA new version information page, the 'immediate upgrading' button can be clicked on the OTA new version information page to perform immediate upgrading operation, at the moment, the 'OTA updating progress' method of the OTA single-instance object is also called to start polling until the 'OTA state' is in the 'in-installation stage', the page is automatically switched to the OTA upgrading page until the final upgrading is completed, and then the polling is ended;
if the OTA is in the "installation stage", the button below "view" can be clicked to enter the OTA upgrade page, and the method of "OTA update progress" of the OTA single-instance object is immediately called to start polling at the moment until the final upgrade is completed, and then the polling is ended.
When the "OTA state" is in the "download stage" and the "in-install stage" both require polling, so the polling condition is ended: when the 'OTA update progress' in the OTA single-instance object polls that the 'OTA state' is not equal to the states in the 'download stage' and the 'install stage' in the state machine and all instructions are issued, the 'OTA update progress' method in the OTA single-instance object forcedly exits the loop, and the polling is ended.
It can be understood that in the element definition of each display interface, the button, that is, the key, corresponds to the instruction display text, and the action after clicking a certain button points to click logic, and the element definition includes a first display key, a second display key, a display animation, a progress display text, a downloading progress identifier, an installation progress identifier, and the like, for example, the button text of the top page is displayed for viewing, and refers to the first display key corresponding to the current state; for example, when the "OTA state" is equal to DOWNLOADING, two buttons are displayed below the page, the button texts are respectively "pause download" and "cancel download", and a progress bar is displayed above the buttons for indicating the current OTA version download progress, at this time, the two buttons corresponding to the "pause download" and "cancel download" are both second display buttons, the progress bar is a download progress identifier, and a specific progress display text determined according to the current progress information can be added, for example, the progress display text 75% is added on the installation progress bar; for another example, when "OTA status" is equal to envirnment_ CHECKING, indicating that the vehicle ENVIRONMENT is detected before upgrading, an animation element is shown on the page, indicating a waiting process, and the animation element is displayed.
The method in the embodiment has the following effects:
