In the invention, the vehicle to be upgraded refers to a vehicle with Over the Air Technology (OTA, English full name: Over the Air Technology), and the vehicle is automatically downloaded with an upgrade package and upgraded through a network. The problem of spatial distance can be solved in an important way, namely, a user does not need to drive the vehicle to an automobile 4S store any more, and partial problems of the vehicle can be solved through software upgrading in any place with a network.
Referring to fig. 1, a first embodiment of the present invention provides a method for remotely upgrading an automatic parking control module, which is applied to a background server of an over-the-air service, and the method includes steps S10-S40:
step S10, acquiring a differential software package uploaded by a module provider and generated based on the comparison difference between a new software package and an old software package;
in one embodiment of the invention, the automatic parking control module is an OTA object in the OTA upgrading service, and the automatic parking control module adopts a software backup function, namely the interior of the ECU is used for two areas, one part is used for storing a currently running program, and the other part is used for storing a backup program. Except for the first installation or the off-line of the equipment, only one piece of software exists in the ECU, and the newly installed software and the last piece of software coexist later. In the use process of the automobile, the current running is the latest software under the general condition, if an error occurs in the upgrading process or the written program cannot run, the interior of the ECU automatically rolls back to the previous program which can run normally, and the error report of the automobile is prevented.
The new software package and the old software package are compared and differentiated, wherein the programs of the new software package and the old software package are basically the same, only a small part of the new software package is used for solving bugs existing in the original program or programs with new functions, and the different part is the differential software package, the software package is small and convenient to transmit, so that the generation of the differential software package through the differential comparison of the two software packages is necessary.
Step S20, identifying and managing the differential software package, and sending the differential software package to a wireless communication module of a vehicle to be upgraded so that the wireless communication module transmits the differential software package to the automatic parking control module through a CAN network;
the wireless communication module (namely T-box) is used for communicating the automobile with the background server, and is connected with other ECUs on the automobile through a CAN bus, so that a new version software package corresponding to the module to be upgraded CAN be downloaded and transmitted through the wireless communication module.
Step S30, controlling the automatic parking control module to trigger a differential reduction assembly so that the differential reduction assembly reduces the differential software package into a new software package;
in an example of the invention, the differential restoration component is equivalent to a plug-in of the automatic parking control module and is also used for restoring the software differential package generated in the earlier stage, so that the old software package can be restored and upgraded into a new software package through the differential restoration component.
And step S40, judging whether the difference software package is successfully restored into the new software package, if so, the automatic parking control module carries out version upgrading based on the new software package.
The specific restoring process is to combine the differential software package into the old software package, replace the program segment with bug in the old software package by the program segment in the differential software package, or write the new program segment in the differential software package into the old software package.
After the difference software package is successfully restored into a new software package, the upgrading process can be directly started to upgrade the automatic parking control module.
By adopting the remote upgrading method for the automatic parking control module shown in the embodiment, the software differential packet generated through difference can be generated by comparing and differentiating the new software packet with the old software packet, the software differential packet occupies a small memory and has high transmission efficiency, the automatic parking control module is upgraded by a mode of restoring the software differential packet into the new program, and the technical defect that the automatic parking control module in the prior art needs longer time for upgrading under the electronic and electric architecture of the original vehicle is overcome.
A second embodiment of the present invention provides a method for remotely upgrading an automatic parking control module, where in the method shown in this embodiment:
in step S10, the step of obtaining the difference software package generated based on the comparison and difference between the new software package and the old software package uploaded by the module provider specifically includes steps S11-S13:
step S11, comparing the image files in the old version software package and the new version software version through a module provider;
step S12, generating a difference software package with a preset format based on the difference part of the old software package and the new software package;
wherein, the difference part of the old software package and the new software package generates a difference software package with the format of hex or S19;
and step S13, acquiring the difference software package uploaded by the module provider.
Specifically, after the module provider uploads the differential software package to the background server, the background server stores, manages and calls the differential software package, and the background server can push the differential software package to all vehicles of the same vehicle type and the same configuration.
In this embodiment, after obtaining the difference software package uploaded by the module provider in the background service area, the background server manages and calls the difference software package, which specifically includes steps S21-S23:
step S21, an upgrade task of the automatic parking control module in the system is created, and the upgrade task is sent to the wireless communication module;
in an example of the present invention, after the background server obtains the differential software package uploaded by the module provider, an upgrade task related to the automatic parking control module is automatically created inside the system, and the background server calls the differential software package corresponding to the vehicle to be upgraded based on the upgrade task and synchronously sends the upgrade task to the wireless communication module of the vehicle to be upgraded.
Step S22, controlling the wireless communication module to read the software version number of the automatic parking control module on the vehicle to be upgraded and uploading the software version number to the background server;
when a vehicle to be upgraded receives an upgrade task of the automatic parking control module, software version numbers, such as software versions V2.0 and V3.0, of the vehicle relative to the automatic parking module are read, and the software version numbers are uploaded to a background server.
Step S23, finding the difference software package corresponding to the software version number in the system, and sending the download link to the wireless communication module, so that the wireless communication module downloads the difference software package corresponding to the software version number.
The background server searches whether a differential software package (such as a software version V3.0) capable of being used for restoring and upgrading an old software package (such as a software version V2.0) exists in a software memory in the system or not based on the uploaded software version number of the automatic parking control module, and after the corresponding differential software package exists, a download address corresponding to the differential software package is sent to the wireless communication module, and the wireless communication module downloads the differential software package.
In this embodiment, after the background server obtains the difference software package uploaded by the module provider, a remote upgrade message should be pushed to the vehicle, and the specific steps include:
pushing a remote upgrading message to a vehicle to be upgraded, and transmitting the difference software package to the automatic parking control module by the wireless communication module after receiving confirmation information of remote upgrading fed back by a user;
specifically, a vehicle manufacturer pushes a remote upgrade message to a vehicle, which indicates that an automatic parking control module of the vehicle can be upgraded to solve possible problems of the existing automatic parking control module in the use process, for example, after a vehicle-mounted central control screen displays the remote upgrade message, a user clicks confirmation information such as 'approval to upgrade' or 'confirmation to upgrade' on the vehicle-mounted central control screen, a wireless communication module downloads a differential software package according to a download address provided by a background server, and the differential software package is transmitted to the automatic parking control module after the download is completed.
Because the differential software package is smaller, the whole downloading and transmitting process consumes less time, the upgrading efficiency of the automatic parking control module is improved, and the time for upgrading is reduced.
After the automatic parking control module receives the differential software package, the differential software package is verified, and if the verification is passed, the differential reduction assembly integrated in the automatic parking control module is triggered.
Specifically, the verifying the differential software package includes that after the automatic parking control module receives the differential software package, the integrity and the legality of the differential software package are verified, if no problem exists in the verification, a differential restoration component integrated in BootLoader software is triggered through a diagnosis 31 routine service, and the step S is executed. If the verification is problematic, the difference software package is not matched with the current old version software package of the automatic parking control module, the failure of upgrading is prompted, and log data of failure reasons are stored in the automatic parking control module.
The differential software package is subjected to reduction upgrading, and the differential reduction assembly continuously feeds back a reduction upgrading result to the automatic parking control module;
and the automatic parking control module sends the state to be upgraded to the wireless communication module so as to enable the vehicle to be in a remote upgrading state.
And before upgrading, the automatic parking control module sends a state to be upgraded to the wireless communication module so as to enable the vehicle to be in a remote upgrading state to inform a user that the current vehicle is in the state to be upgraded, and if the vehicle needs to be continuously upgraded, the power failure of the vehicle is avoided.
And after the wireless communication module receives the upgrade success signal of the automatic parking control module, the wireless communication module checks the software version to confirm that the version is correct, and sends an upgrade success signal to other control units through the CAN bus, so that the wireless communication module exits the remote upgrade mode.
In the upgrading process of the automatic parking control module, the automatic parking control module sends the upgrading state to the wireless communication module at any time, when the automatic parking control module is upgraded, an upgrading completion signal is sent to the wireless communication module, and the wireless communication module CAN send an upgrading success signal to other control units through the CAN bus.
By adopting the remote upgrading method for the automatic parking control module, the software differential packet generated through difference can be generated by comparing and differentiating the new software packet with the old software packet, the software differential packet occupies a small memory and has high transmission efficiency, and the automatic parking control module is upgraded by restoring the software differential packet into the new program, so that the technical defect that the automatic parking control module in the prior art needs longer time for upgrading under the original vehicle electronic and electrical architecture is overcome.
