Detailed Description
The following description of the exemplary embodiments of the present application, taken in conjunction with the accompanying drawings, includes various details of the embodiments of the application to assist in understanding, which are to be considered exemplary only. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present application. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
In a first aspect, an embodiment of the present application provides a vehicle upgrade method, which is applied to a terminal device, and as shown in fig. 1, the method includes:
s101: receiving an upgrading task which is pushed by a cloud and aims at a target vehicle;
s102: downloading the upgrading packet corresponding to the upgrading task aiming at the target vehicle from a downloading server;
s103: and under the condition that communication connection is established with the target vehicle, the upgrade package is sent to the target vehicle.
The terminal device may be an intelligent terminal or a mobile terminal used after use, for example, a mobile phone, a tablet computer, or the like.
S101 may specifically be: the terminal equipment receives an upgrading task aiming at a target vehicle sent by a first server at the cloud. The first server can be a server which is used by the cloud end for pushing tasks to the terminal device and/or the target vehicle.
Wherein, the upgrade task may include at least one of the following: the target vehicle identification, the download address of at least one upgrade package to be downloaded, and the upgrade constraint condition of at least one upgrade package to be downloaded.
Of course, the upgrade task may also include more contents, which are not exhaustive here.
Before executing S102, the method may further include:
the terminal equipment sends a downloading request to a first server at the cloud end.
For example, a user can check whether an upgrade task sent by the cloud exists by checking the preset application of the terminal device, and if a new upgrade task exists, the user can select the terminal device side to download, and at the moment, the terminal device can send an upgrade package download request aiming at the upgrade task to the cloud.
Furthermore, a user can see that at least one upgrade package to be downloaded currently exists when viewing the display content of the preset software; accordingly, one or more upgrade packages may be selected for downloading, or all upgrade packages may be selected for downloading, which may be determined according to specific situations. If the one or more upgrade packages are downloaded, the user can click on the operation interface and then sends a download request containing the one or more upgrade packages to the cloud. If all the upgrade packages are downloaded, the user can select all the upgrade packages on the operation interface, and then the terminal equipment sends a downloading request for downloading all the upgrade packages to the cloud.
The function of sending the download request to the first server in the cloud may be to notify that the upgrade package included in the download request is downloaded by the terminal device, and at this time, if the target vehicle has started downloading the upgrade package from the download server, the cloud may send a download change instruction to the target vehicle to instruct the target vehicle to stop downloading the upgrade package.
And then the terminal equipment executes S102, and downloads the upgrading packet corresponding to the upgrading task aiming at the target vehicle from a downloading server.
Specifically, the terminal device may download the at least one upgrade package for the target vehicle from a download address corresponding to the download server according to a download address of the at least one upgrade package included in the upgrade task.
After the execution is completed S102, the terminal device may download the content of the entire upgrade package.
Before S103 is executed, the terminal device may first establish a communication connection with the target vehicle.
Here, the communication connection may be a WIFI connection.
And then S103 is executed, and all upgrade packages currently downloaded by the terminal equipment are sent to the target vehicle through WIFI connection.
To this end, the terminal device completes the processing as an intermediary device between the download server and the target vehicle.
Through the processing, the terminal device sends the upgrade package to the target vehicle through the connection between the terminal device and the target vehicle, so that the flow consumption caused by the fact that the target vehicle directly obtains the upgrade package from the download server can be reduced.
In another embodiment, as shown in fig. 2, the method may further include:
s201: receiving a new version update notification of the target vehicle;
s202: if the target vehicle is confirmed to be upgraded, sending an upgrading instruction to the target vehicle; wherein the upgrade instruction is used for instructing the target vehicle to execute upgrade based on the upgrade package.
Specifically, in S201, it may be considered that the terminal device may check the system state of the current target vehicle through the preset application in real time, and if the target vehicle completes downloading the upgrade package, the terminal device may receive a new version update notification of the target vehicle. The new version update notification may be used to indicate that the target vehicle completed downloading the new upgrade package, or to indicate that the target vehicle needs to be updated according to the new upgrade package.
Of course, the new version update notification of the target vehicle may also be acquired through an SMS message, and the embodiment does not exhaust the acquisition manner.
In S202, the upgrade of the target vehicle is confirmed, and the confirmation information may be generated in response to the user clicking an option for confirming the upgrade through the preset application.
At this time, it should be further noted that:
carrying out validity check on the upgrade package;
and receiving temporary permission information sent by the target vehicle when the validity check is passed.
Specifically, the processing of checking the validity of the upgrade package may be executed after confirming that the target vehicle is upgraded; if the validity check is passed, the information that the check is passed can be sent to the target vehicle.
Correspondingly, when receiving the information that the verification is passed and sent by the terminal equipment, the target vehicle can detect the state of the target vehicle, if the current state is the dormant state, the target vehicle is awakened, and the target vehicle verifies the upgrade package again, otherwise, if the current state is the working state, the target vehicle directly verifies the upgrade package again.
Certainly, the processing of determining the state of the target vehicle may also be performed by a terminal device, that is, the terminal device detects the state of the target vehicle when the terminal device completes the verification for the upgrade package and the verification passes, if the state of the target vehicle is a dormant state, the terminal device may wake up the target vehicle remotely, and when the target vehicle receives a remote wake-up instruction, the terminal device is switched to a working state, and then the target vehicle may verify the upgrade package; or, when the terminal device detects that the state of the target vehicle is the working state, the terminal device may directly notify the target vehicle that the upgrade package is to be upgraded currently, and then the target vehicle may perform the process of verifying the upgrade package.
That is, in combination with the foregoing embodiment, the upgrade package may be verified twice, once at the terminal device and once at the target vehicle; the two verification can be called validity verification, and the verification processing and the content can be the same; of course, the two checks may also include other checks such as validity check, and the purpose of performing the two checks is to make the check more accurate or safer. The validity check and the validity check are performed based on a preset policy, which is not described herein.
Further, in the case that the target vehicle completes verification and the verification is passed, the target vehicle may generate a temporary license message (or referred to as a temporary license); the target vehicle may transmit the temporary permission information to the terminal device.
It should be noted that the temporary license information may further include a valid duration, for example, may be set to 10 minutes, or may be set to 1 day. That is, the valid duration of the temporary license information may be used to limit the available time of the information. The valid duration may be timed from the time of generation, or may be timed from the time of transmission to the terminal device.
Correspondingly, after receiving the temporary license information, if the terminal device performs immediate upgrade, the terminal device may send an upgrade instruction carrying the temporary license information to the target vehicle.
Then, after receiving the upgrade instruction, the target vehicle may verify the temporary permission information in the upgrade instruction, and if the verification is passed, may perform upgrade processing (or referred to as flash processing) on the upgrade package based on the upgrade instruction.
Here, the target vehicle may perform the verification of the temporary license information again to enhance the safety. Further, since the temporary permission information includes the valid duration, when the verification of the temporary permission information is performed, the verification may be performed with respect to the valid duration of the temporary permission information, and if it is determined that the current time exceeds the valid duration, the verification fails; if the current time is within the valid duration, the content of the temporary license information can be further verified.
And the terminal equipment controls the target vehicle to finish the processing of immediate upgrading.
Another embodiment, as shown in fig. 3, may further include:
s301: receiving a new version update notification of the target vehicle;
s302: if the target vehicle is confirmed to be reserved and upgraded, a reservation upgrading instruction is sent to the target vehicle; the reserved upgrading instruction comprises reserved upgrading time, and the reserved upgrading instruction is used for indicating the target vehicle to execute upgrading based on the upgrading package at the reserved upgrading time.
The present embodiment differs from the foregoing embodiments in that the present embodiment controls the processing of the target vehicle to be upgraded at the scheduled upgrade time by the terminal device. In particular, the present invention relates to a method for producing,
s301 is the same as the process of S201 described above, and is not described here again.
In S302, the upgrade of the target vehicle is confirmed, which may be confirmation information generated in response to the user clicking an option for confirming the upgrade through the preset application, and at this time, the user may also set the upgrade reservation time through the preset application.
The reserved upgrading time can be set according to actual conditions, and the time that the user cannot use the target vehicle can be selected to upgrade the target vehicle, so that the problem that the target vehicle cannot be used due to communication silence and power-off in the upgrading process is avoided. For example, at 8 am, the upgrade time may be scheduled to 10 pm, or may be 2 pm, etc.
At this time, it should be further noted that the processing in S302 may also include: carrying out validity check on the upgrade package; and receiving temporary permission information sent by the target vehicle when the legality check is passed. The processing of this part is the same as the previous embodiment and will not be described again.
The difference is that the terminal equipment controls the reservation upgrading after receiving the temporary permission information and sends a reservation upgrading instruction to the target vehicle.
Correspondingly, after the target vehicle receives the upgrading instruction, the target vehicle can firstly store the reserved upgrading instruction and extract the reserved upgrading time; then judging whether the current time reaches the appointed upgrading time;
when the current time reaches the reserved upgrading time, the target vehicle can verify the temporary permission information in the reserved upgrading instruction, and if the temporary permission information passes the verification, upgrading processing (or called flashing processing) can be executed on the upgrading packet based on the reserved upgrading instruction.
Here, the target vehicle may perform the verification of the temporary license information again to enhance the safety. Furthermore, since the temporary permission information includes the valid duration, when the temporary permission information is verified, the valid duration of the temporary permission information can be verified, and if the current time is judged to exceed the valid duration, the verification fails; if the current time is within the valid duration, the content of the temporary license information may be further verified, for example, consistency verification may be performed, that is, whether the temporary license information sent by the terminal device is consistent with a temporary license instruction generated before the terminal device itself, and the like.
And the terminal equipment controls the target vehicle to finish the processing of the reserved upgrade.
In a second aspect, an embodiment of the present application provides a vehicle upgrade method, which is applied to a vehicle, and as shown in fig. 4, the method includes:
s401: establishing communication connection with the terminal equipment;
s402: acquiring an upgrade package from the terminal device through the communication connection established with the terminal device;
s403: performing an upgrade based on the upgrade package.
The terminal device may be an intelligent terminal or a mobile terminal used after use, for example, a mobile phone, a tablet computer, or the like.
S401 may specifically be: and the terminal equipment establishes communication connection with the vehicle. Here, the communication connection may be a WIFI connection.
Then, S402 is executed, which may include the following two scenarios:
scene one,
The method can comprise the following steps: and if the vehicle does not download any new upgrade package of the upgrade task, the vehicle acquires the upgrade package from the terminal equipment through the communication connection connected with the terminal equipment, and executes S403 to upgrade the upgrade package. The scenario can be understood that the terminal device serves as an intermediary device for transmitting the upgrade package to transmit all the upgrade packages corresponding to the upgrade tasks to the vehicle.
In the scene, the vehicle can receive an upgrading task through connection with a first server at the cloud end; of course, the process of receiving the upgrade task may not be performed. Here, the first server may be a server used by the cloud for pushing tasks to the terminal device and/or the target vehicle. Wherein, the upgrade task may include at least one of the following: the target vehicle identification, the download address of at least one upgrade package to be downloaded, and the upgrade constraint condition of at least one upgrade package to be downloaded. Of course, the upgrade task may also include more contents, which are not exhaustive here.
Further, the air conditioner is provided with a fan,
if the vehicle does not receive an upgrade task from the first server in the cloud, it may wait to perform S401-S403.
If the vehicle receives the upgrade task from the first server in the cloud, the vehicle may wait to execute S401 to S403 instead of downloading the upgrade package corresponding to the upgrade task from the download server according to the control of the user.
Of course, the user may control the vehicle to download the upgrade package corresponding to the upgrade task from the server based on the upgrade task. It should be understood that S401-S403 may not be executed if the vehicle acquires the contents of all upgrade packages from the download server, and this processing will not be described in detail in this embodiment.
Scene two:
receiving an upgrading task pushed by a cloud end; downloading an upgrading packet corresponding to the upgrading task from a downloading server based on the upgrading task; and
and in the process of downloading the upgrade package corresponding to the upgrade task from the download server, under the condition of receiving a download change instruction sent by a cloud end, stopping downloading the upgrade package from the server, and storing the upgrade package as an undelivered data package.
That is, if the vehicle receives a download change instruction sent by the first server in the cloud during the downloading process of downloading the upgrade package from the download server, the vehicle controls to stop the downloading process; correspondingly, the upgrade package is stored as the upgrade package which is not downloaded.
The processing of S402 in this scenario includes:
under the condition that the communication connection with the terminal equipment is detected, judging whether an upgrading packet which is not downloaded is present;
and if the unfinished downloaded upgrade package exists, performing breakpoint continuous transmission on the unfinished downloaded upgrade package through communication connection with the terminal equipment.
It should be noted that if one upgrade task of the vehicle includes a plurality of upgrade packages, there may be a portion of the upgrade packages that are incomplete to be downloaded, and another portion of the upgrade packages that are not started to be downloaded, the upgrade packages that are incomplete to be downloaded are processed according to scenario two, and the upgrade packages that are not started to be downloaded are processed according to the flow of scenario one. The description will not be repeated.
And finally executing S403 to execute upgrading processing on the upgrading packet.
Through the processing, the terminal device sends the upgrade package to the target vehicle through the connection between the terminal device and the target vehicle, so that the flow consumption caused by the fact that the target vehicle directly obtains the upgrade package from the download server can be reduced.
In another embodiment, the scheme may further include:
checking the upgrade package;
and generating temporary permission information and sending the temporary permission information to the terminal equipment under the condition that the verification is passed.
Specifically, the vehicle may detect a state of the vehicle when receiving information that validity check sent by the terminal device passes, wake up the vehicle if the current state is a dormant state, check the upgrade package by the vehicle, and otherwise, check the upgrade package by the vehicle directly again if the current state is a working state.
With the combination of the foregoing embodiments, the upgrade package may be verified twice, once executed at the terminal device, and once executed at the target vehicle; both of the two checks may be referred to as validity checks, the processing and content of the checks may be the same, and the purpose of performing both checks is to make the checks more accurate or safer to consider.
Further, in the case that the vehicle completes verification of the upgrade package and verifies that the upgrade package passes, the vehicle may generate a temporary license message (or referred to as a temporary license); and sending the temporary permission information to the terminal equipment.
It should be noted that the temporary license information may further include a valid duration, for example, may be set to 10 minutes, or may be set to 1 day. That is, the valid duration of the temporary license information can be used to limit the available time of the information. The valid duration may be timed from the time of generation, or may be timed from the time of transmission to the terminal device.
Further, the vehicle can perform both immediate upgrade and reservation upgrade processes based on the control of the terminal device. Respectively speaking:
in the process of immediate upgrade:
receiving an upgrading instruction sent by the terminal equipment;
and performing upgrading on the upgrading packet based on the upgrading instruction.
The upgrade instruction carries the temporary permission information; correspondingly, the performing upgrade on the upgrade package based on the upgrade instruction includes: verifying the temporary permission information carried in the upgrading instruction; and in the case of passing the verification, performing upgrading based on the upgrade package.
Here, after receiving the upgrade instruction, the vehicle may verify the temporary permission information in the upgrade instruction, and if the verification is passed, may perform upgrade processing (or referred to as flash processing) on the upgrade package based on the upgrade instruction. The vehicle performs the verification of the temporary license information again to enhance the safety. Furthermore, since the temporary permission information includes the valid duration, when the temporary permission information is verified, the valid duration of the temporary permission information can be verified, and if the current time is judged to exceed the valid duration, the verification fails; if the current time is within the valid duration, the content of the temporary license information can be further verified.
And the terminal equipment controls the target vehicle to finish the processing of immediate upgrading.
In the processing of reservation upgrading:
receiving an appointment upgrading instruction sent by the terminal equipment; the reservation upgrading instruction comprises reservation upgrading time; and at the reserved upgrading time, upgrading is executed based on the upgrading package.
The reservation upgrading instruction also comprises the temporary license information;
correspondingly, the performing of upgrade based on the upgrade package at the upgrade reservation time includes:
at the appointed upgrading time, verifying the temporary permission information carried in the appointed upgrading instruction; and in the case of passing the verification, performing upgrading based on the upgrade package.
The reserved upgrading time can be set by a user according to actual conditions at the terminal equipment, and the time that the user cannot use the target vehicle can be selected to upgrade the target vehicle, so that the problem that the target vehicle cannot be used due to communication silence and power-off in the upgrading process is avoided. For example, 8 am may be the current time, 10 pm may be the upgrade time scheduled, or 2 pm may be the current time, and so on.
When the vehicle receives the reservation upgrading instruction, the vehicle firstly stores the reservation upgrading instruction and extracts the reservation upgrading time; judging whether the current time reaches the appointed upgrading time or not;
when the current time reaches the scheduled upgrade time, the vehicle may verify the temporary permission information in the upgrade instruction, and if the verification is passed, the upgrade process (or referred to as a flash process) may be performed on the upgrade package based on the upgrade instruction.
Before the vehicle can verify the temporary permission information in the upgrade order, the vehicle can also acquire the state of the vehicle, and if the current state is a working state, the vehicle can execute the process of verifying the temporary permission information in the upgrade order; and if the current state is the dormant state, waking up the vehicle, and then verifying the temporary permission information in the upgrading instruction.
Here, the target vehicle may again perform the verification of the temporary permission information to improve safety. Further, since the temporary permission information includes the valid duration, when the verification of the temporary permission information is performed, the verification may be performed with respect to the valid duration of the temporary permission information, and if it is determined that the current time exceeds the valid duration, the verification fails; if the current time is within the valid duration, the content of the temporary license information can be further verified.
And the terminal equipment controls the target vehicle to finish the processing of the reserved upgrade.
As shown in fig. 5, an example of this embodiment specifically describes, by taking a terminal device as a mobile phone and specifically implementing the processing of the foregoing method through a mobile phone APP, the following: the cloud may include an OTA platform and a TSP platform, where the TSP platform may be understood as the aforementioned first server (of course, may also be understood as a first server cluster, which are all within the scope of the present embodiment), and the OTA (Over-the-Air) platform may be understood as a second server or a second server cluster, which is used to push a new upgrade task to the TSP, and the present embodiment does not describe this in detail.
As shown in fig. 5, the cloud may push an upgrade task to the mobile phone APP and the vehicle; when the vehicle (specifically, the OTA component of the vehicle) receives the pushed upgrade task, the vehicle can select itself to download the upgrade package from the download server (i.e., CDN). Or, the mobile phone APP may notify the cloud to execute mobile phone downloading based on the operation of the user, that is, may send a mobile phone downloading request to the cloud; at this time, it is possible that the vehicle has already downloaded a part of the upgrade package, once the cloud receives the mobile phone download request sent by the mobile phone APP, a download change instruction may be sent to the vehicle, and correspondingly, the vehicle may stop downloading the upgrade package after receiving the download change instruction.
Still referring to fig. 5, after the mobile phone APP sends a mobile phone download request to the cloud, the upgrade package may be downloaded from the download server according to the upgrade task; and then, under the condition that the WIFI connection is established between the mobile phone and the vehicle, breakpoint continuous transmission can be carried out on the vehicle, so that the vehicle can obtain all contents of the upgrade package corresponding to the task through the mobile phone APP.
As yet another example, the cell phone controls the processing of the vehicle for immediate upgrade, see FIG. 6, where the grey boxes may be the processing performed by the vehicle. Specifically, the method may include: after detecting the new version update notification, the mobile phone can confirm the update in response to the click of the user, and then the mobile phone executes the validity check for the update package;
if the verification is passed, the vehicle can be controlled to carry out state self-check; if the vehicle detects that the state of the vehicle is a dormant state, the vehicle is awakened, then the vehicle also performs one-time upgrade package verification, and if the vehicle detects that the state of the vehicle is a working state, the vehicle directly performs verification processing;
based on the verification processing, the vehicle generates temporary license information and then sends the temporary license information to the mobile phone; the mobile phone sends an upgrading instruction to the vehicle, wherein the upgrading instruction carries temporary permission information;
and the vehicle checks the temporary permission information in the upgrading instruction, and if the temporary permission information passes the checking, the vehicle condition is checked, and then the upgrading is executed. Here, the checking of the vehicle condition may further include: the vehicle condition is checked according to a preset strategy, for example, when the current vehicle is running, the upgrading can not be executed, and the vehicle controls the upgrading under the running stopping state (for example, the situation of engaging a stopping gear) or the power-off state.
As yet another example, the handset controls the processing of the vehicle reservation upgrade, see FIG. 7, where the grey boxes may be the processing performed for the vehicle. Specifically, the method may include: after detecting the new version update notification, the mobile phone can confirm the reserved upgrade in response to the click of the user, and then the mobile phone executes the validity check aiming at the upgrade package;
