Step 103: and after downloading the upgrade packages of all the ECUs to be upgraded under the latest overall version, the local communication server executes the upgrade operation of all the ECUs to be upgraded according to the received upgrade execution instruction and the downloaded upgrade packages of the ECUs.
According to the embodiment of the OTA upgrading method of the local communication server of the transportation tool, when the OTA upgrading information comprising the latest integral version is received by the cloud server, the integral upgrading packet is generated, and the upgrading notification information is generated and continuously sent according to the integral upgrading packet, so that the local communication server of each transportation tool with a target model can automatically receive the upgrading notification information as long as the local communication server is positioned in a mobile communication signal coverage area, and the upgrading notification information in the OTA process is accurately issued and the upgrading packet can be completely downloaded into the local communication server; meanwhile, the latest integral version of the integral upgrade package is uniformly managed, the local communication server executes the upgrade operation of all the ECUs to be upgraded after downloading all the upgrade packages of all the ECUs to be upgraded under the latest integral version, the version information of all the ECUs of all the transportation means can be definitely and conveniently managed, downloading and upgrading are automatically carried out, the use experience of a user is improved, the operation of the user is simplified, and the waiting time of the user is saved.
As shown in fig. 2, the OTA upgrading method for a local communication server of a transportation vehicle provided by the present invention is a preferred implementation manner ofstep 101 andstep 102 in the embodiment of the method shown in fig. 1, an explanation of the embodiment shown in fig. 1 may be applied to this embodiment, an OTA upgrading method for a local communication server of this embodiment is explained by taking a transportation vehicle as an example, and the method includes:
step 201: the cloud server providing the upgrading service maintains upgrading packages of specific transportation tools of various types, integral version information (namely the integral vehicle version information) and version information of various ECUs;
step 202: the cloud server generates an integral upgrade package (namely an integral vehicle upgrade package) when receiving OTA upgrade information comprising the latest integral version;
step 203: the cloud server generates and continuously sends upgrading notification information to TBOX of all vehicles of the target vehicle type according to the whole upgrading packet;
step 204: once the TBOX of the vehicle enters a mobile communication signal coverage area, the vehicle receives upgrade notification information;
step 205: the TBOX of the vehicle compares the whole upgrade package with the current version of each ECU of the vehicle;
step 206: and determining the ECU with the current version inconsistent with the latest software version information of the corresponding ECU in the whole upgrade package as the ECU needing to be upgraded, adding the ECU into an upgrade queue, and downloading the corresponding upgrade package according to a download address (such as URL) in the whole upgrade package.
Step 207: and finishing downloading the upgrade packages of all ECUs needing to be upgraded under the latest overall version.
During specific operation, the technology of network disconnection and power-off continuous transmission can be utilized, the flow waste caused by the fact that the ECU needs to be downloaded from the head after network disconnection and power-off every time is avoided, meanwhile, the upgrading package of each ECU contained in the whole vehicle version can be stored in a URL, the software version information of all the ECUs of the vehicle is maintained in TBOX, when a new OTA upgrading notice is received, the updated ECU downloads the upgrading package of each ECU in the whole vehicle package compared with the current version number of the ECU, the ECU which is not updated does not perform downloading processing, and the (4G) network flow is saved by completely downloading the whole upgrading package.
In the present embodiment, each ECU has its own software version, and version management is performed by using the entire version, for example, the entire vehicle version information includes version information of all ECUs. The method comprises the steps that a vehicle manufacturer issues a whole vehicle version of a specified vehicle type, under the condition that a user does not know, a cloud server informs that a whole vehicle has an updated message, the message is issued to TBOX of all vehicles of the vehicle type through a (4G) network, an issuing mode adopts a 'issuing-subscribing' mode, namely, a cloud server issues a message that the whole vehicle OTA has upgrade, the message is always stored in a issuing cache of the cloud server before all vehicles feed back the upgrade city or a next new version is issued, once vehicles of corresponding vehicle types enter a region covered by (4G) signals to be accessed into an Ethernet, the TBOX receives the message that the whole vehicle has the update through subscription, and therefore 'the message must be answered' is achieved. After OTA upgrade notice is issued by a background server of a car factory, once a vehicle of a corresponding vehicle type is accessed to a network, the upgrade notice is necessarily received, URL information of an upgrade package of each ECU in an integral upgrade package is automatically analyzed, and then the upgrade package is silently downloaded without being known by a user.
In the embodiment, the time for the TBOX to download the upgrade package from the cloud server due to the influence of network coverage is reduced in the time for waiting for upgrading by the user, the cloud server performs version management on all vehicle-mounted electronic equipment by taking the whole vehicle version as a unit, the method is more convenient and efficient, and the complexity can be reduced for differential upgrading; the user's experience of upgrading the progress bar is very good.
Fig. 3 is a preferred implementation manner ofstep 103 in the embodiment of the method shown in fig. 1, where an explanation of the embodiment shown in fig. 1 may be applied to this embodiment, and the OTA upgrading method of the local communication server of this embodiment is explained by taking a transportation vehicle as an example, where the method includes:
step 301: after downloading all the upgrading packages of the ECUs to be upgraded under the latest overall version, the local communication server verifies all the upgrading packages of the ECUs to be upgraded and sends upgrading inquiry information to the operation end after verification is completed;
step 302: TBOX informs intelligent central control and mobile phone terminal that whole vehicle software is updated
Step 303: and the operation end sends the upgrade execution instruction or appoints upgrade time, and comprises a user terminal or an intelligent central control end.
Step 304: after the upgrading execution instruction is received, checking whether a preset upgrading condition is met, wherein the upgrading condition comprises gear information and residual electric quantity of the vehicle;
step 305: when the preset upgrading conditions are met, sequentially carrying out upgrading operation on all ECUs needing upgrading; the specific upgrade flashing process can refer to the process shown in fig. 4;
step 306: displaying upgrading progress information to the operation end in the upgrading process; the specific process of sending the progress bar may refer to the process shown in fig. 4.
The writing of TBOX to the ECU necessarily requires that a user cannot use the vehicle, because the ECU which does not have double partitions is in a programming state during software burning and cannot work normally. Due to the fact that the logic of whole vehicle upgrading is adopted, a user does not need to pay attention to the details of the dependency relationship, the upgrading sequence and the like, and the upgrading time and the progress bar pre-estimated by the user can be displayed by the central control or the mobile phone end, so that the upgrading experience of daily intelligent equipment like mobile phones is more approximate. In order to show the upgrading progress more intuitively for a user, the ECU upgrading packet is tested before being issued to obtain the average value of the brushing time length as a reference, the reference upgrading time of the ECUs needing upgrading under the version of the whole vehicle is accumulated to be used as the total estimated upgrading time, and the percentage is calculated in a weighting mode when each ECU is upgraded when the progress bar is shown at the central control or the mobile phone end in the process of sequential upgrading.
Step 307: judging whether the upgrading operation is normally performed, and if the upgrading operation is abnormal, repeating thestep 304 for a preset number of times, such as failure;
step 308: and when the upgrade is completed or fails, respectively sending first upgrade feedback information and second upgrade feedback information to the operation end.
In this embodiment, after the upgrade package is downloaded, the TBOX sends a new OTA upgrade notification to the central control screen of the vehicle or the mobile phone of the vehicle owner, which means that the long process of "downloading the upgrade package" is silently performed by the vehicle by using each time of accessing the 4G network, and the user does not need to occupy time to actively download and wait for the end. After the user receives the notice of the new integral upgrade package on the central control screen or the mobile phone end, the upgrade package is downloaded to the vehicle-mounted TBOX disk, so that the user does not depend on the existence of the 4G network when selecting 'upgrade immediately' or 'upgrade with reserved time' to start the flash process of the TBOX to the ECU.
