The vehicle upgrading method comprises the following steps.
And step S1, determining a module to be upgraded of the vehicle controller.
Specifically, the vehicle controller includes a plurality of modules, and the vehicle upgrade includes an overall upgrade and an upgrade of a portion of the modules, and therefore, the upgrade process needs to be preceded by a determination that the module of the vehicle needs to be upgraded.
Wherein, step S1 specifically includes:
sending query information to a server;
receiving feedback information sent by the server, wherein the feedback information carries the latest software version of a controller, and the vehicle controller comprises a plurality of modules; such as a display module, a sound module, etc.
Judging whether the software version of the vehicle is matched with the latest software version;
and determining a module corresponding to the unmatched software version, wherein the module is the module to be upgraded.
In an embodiment of the present application, a plurality of modules in the controller have an association relationship, for example, the display module and the shooting module, and if the display module needs to be upgraded, the shooting module also needs to be upgraded correspondingly, so that the display module is adapted conveniently.
Specifically, the vehicle upgrading method further includes:
acquiring an incidence relation among a plurality of modules;
and adjusting the module to be upgraded according to the incidence relation.
In one embodiment, the server sends a query message to the vehicle to obtain the vehicle software version, compares the latest software version with the vehicle software version, and sends an upgrade instruction to the vehicle if the vehicle software version is not the latest version, wherein the upgrade instruction carries a module to be upgraded of the vehicle.
In another embodiment, the vehicle sends a query message to the server to obtain the latest version of the vehicle software, and the software versions of the vehicle are compared to determine the module of the vehicle to be upgraded.
And step S2, acquiring the storage position of the upgrade package corresponding to the module to be upgraded.
Optionally, the storage location of the upgrade package may be location information preset in the vehicle storage area, and the vehicle may obtain the location of the upgrade version according to the location information;
optionally, the server periodically pushes the location information of the upgrade package to the vehicle.
And step S3, compressing the upgrade package.
Optionally, the vehicle controller receives the process of the upgrade package while compressing the upgrade package.
Optionally, the vehicle controller sends a compression instruction to the server, so that the server storing the upgrade package compresses the data package according to the compression instruction of the controller.
Therefore, by compressing the upgrade package, the transmission time of the upgrade package can be reduced, and the storage space of the upgrade package can be saved.
Optionally, in an embodiment of the present application, before the step S3, the positioning method further includes:
determining the size of an upgrade package according to the module to be upgraded;
judging whether the size of the upgrade package is larger than a preset value or not;
if so, compressing the upgrade package.
If not, enabling the vehicle to enter a common upgrading mode.
The general upgrading mode is the existing upgrading mode of the vehicle, and all processes related to vehicle upgrading, including target data erasing, data transmission, data writing, data verification, logistics writing and the like, are completed in the BOOTLOADER.
The vehicle upgrading method is mainly applied to the upgrading process that the upgrading module is large, namely the upgrading package is large. Through this application make vehicle upgrading process's upgrading package transmission and upgrading package write in and go on in the mode of difference, upgrade package transmission promptly goes on when the vehicle is in the mode, and the upgrading package is write in and is gone on when the vehicle is in the mode of upgrading to reduce the time that the vehicle is in the mode of upgrading, promote upgrading efficiency. However, if the module to be upgraded is small, for example, the upgrade package is smaller than 512K, the module can be upgraded in a normal upgrade mode. It can be understood that, the above comparison is performed only by using the existing upgrade mode, and the upgrade method provided by the present application can also be applied to upgrade with a smaller upgrade package.
And step S4, confirming that the vehicle is in the working mode, and controlling the application program to transmit the upgrade package from the storage position to the reserved area of the controller.
By confirming that the vehicle is in the working mode, the electric quantity of the vehicle storage battery is not influenced in the process of transmitting the upgrade package from the storage position to the reserved area of the controller.
Specifically, the upgrade package is transmitted through the application program when the engine of the vehicle is in an operating state. Therefore, when the upgrade package is transmitted to the vehicle controller from the server, a user does not sense the upgrade package and the normal operation of the vehicle is not affected. In the prior art, the transmission of the upgrade package is performed by a bus of the controller, the bus is slow in data transmission, and the vehicle needs to be in a non-working mode when the bus transmits data.
Please refer to fig. 2, wherein the reserved area is a reserved storage space in the controller, and is mainly used for providing a flash storage space required for upgrading a new function, the storage space does not participate in normal use of the controller, and the size of the storage space is 30% to 40% of the storage space of the controller.
The vehicle controller comprises an application program and a bootloader program, wherein the application program is a program executed in the normal use process of the vehicle and executes the normal functions of the vehicle controller, and the bootloader program is used for the normal application program and needs to be updated and upgraded. The two programs are in the same Micro Controller Unit (MCU), and the vehicle upgrading method provided by the application comprises the following steps: and the downloading and transmission of the upgrade package are executed by the application program, and the writing process of the upgrade package is still executed by the bootloader program, wherein the writing of the upgrade package comprises the decompression of the upgrade package, the writing of the upgrade package and the verification of the upgrade.
And step S5, confirming that the vehicle enters an upgrading mode, decompressing the upgrading packet to a target area of the module to be upgraded, and upgrading the module to be upgraded.
The upgrade mode is that the vehicle is in a power-on state and the vehicle is in a no-task state.
Specifically, the upgrading packet of the reserved area is decompressed and written into a target area of the module to be upgraded, specifically including erasing, writing, verifying and writing of logistics data of the target area, so that the module to be upgraded is upgraded. The upgrade process is the same as the upgrade process of the existing bootloader program, and therefore, the description is omitted here, except that the bootloader program needs to perform decompression of the upgrade package extraction in the reserved area.
So, this application goes on the transmission of upgrading the package and the write-in of upgrading the package at the different modes of vehicle respectively, so, the vehicle transmits the upgrading package when being in mode, only the electric quantity of the battery of the write-in process use vehicle of upgrading the package, and the transmission of data package accounts for 70% ~ 80% time of whole upgrading process in the whole upgrading process, this time all carries out when the vehicle normally works, the user does not have the perception, the upgrading package write-in process time is shorter, and then reduced the shared time of upgrading mode, in order to prevent to lead to the battery feed of vehicle because of upgrading.
In an embodiment of the present application, referring to fig. 3, step S4 specifically includes:
step S41: and judging whether the vehicle enters a working mode or not.
The working mode of the vehicle can be determined by judging whether the engine is started or not or whether the gear of the vehicle is in a D gear or not.
If not, go to step S46: no data transfer operation, i.e., no transmission of the upgrade package, is performed.
If so, go to step S42: and detecting the identification bit of the reserved area of the controller to judge the state of the reserved area.
Specifically, the application program may enter a data transmission mode after receiving a response to the request, and when receiving the data transmission request, detect whether the flag of the reserved area is full FF, and if so, indicate that the reserved area has just executed data erasure, and the reserved area is in an erasure state, and then the application program may execute the first data transmission. If the data transmission state is not the full FF state, the reserved area is in the data transmission state.
Step S43: and if the reserved area is in an erasing state, controlling the application program to transmit the compressed data to the reserved area of the vehicle controller.
Specifically, the reserved area has been erased and no data packet is stored, and the program can be controlled to perform the first data transmission, i.e. to transmit the upgrade packet to the reserved area.
Step S44: and if the reserved area is in a data transmission state, acquiring the breakpoint position of the upgrade package in the reserved area.
Specifically, the upgrade package exists in the reserved area, but the upgrade package is not transmitted completely, the latest transmission breakpoint of the upgrade package is obtained, and the application program continues to transmit the upgrade package to the reserved area according to the breakpoint position, so that breakpoint transmission is continued.
Step S45: and enabling the application program to continuously transmit the upgrade package to the reserved area of the vehicle controller according to the breakpoint position.
Specifically, different data transmission is executed by judging the state in the reserved area, if the data transmission is the first data transmission, the compressed data is directly transmitted, and if the data transmission is not the first data transmission, the breakpoint of the last data transmission needs to be determined, and the subsequent data is transmitted according to the breakpoint, so that breakpoint continuous transmission is realized. Therefore, the transmission of the upgrade package can adapt to different vehicle running states through breakpoint continuous transmission.
Optionally, whether the vehicle executes the erasing operation can be judged through the identification position; if not, erasing the reserved area to enable the reserved area to be in an erasing state, so that the application program can transmit the data to the reserved area.
Further, the vehicle upgrading method further comprises the following steps:
checking whether the upgrade package in the reserved area is complete;
if so, updating the identification bit to indicate that the upgrade package is completely transmitted;
if not, erasing the reserved area so that the application program retransmits the upgrade package.
Specifically, after the data transmission is completed, data checking is performed, for example, data is checked through CRC, and if the data is checked to be correct, a flag bit is set to indicate that the transmission of the upgrade package is completed; if the verification fails, the reserved area is erased, and the upgrade package is retransmitted.
Therefore, the integrity of the data packet in the reserved area is ensured by checking the data packet.
In an embodiment of the present application, step S5 specifically includes:
controlling the module to be upgraded to enter a refresh session mode;
extracting a corresponding upgrading packet in the reserved area based on a module to be upgraded;
decompressing the upgrade package;
erasing the module to be upgraded;
and writing the upgrade package into the module to be upgraded.
Specifically, the module to be upgraded is controlled to enter a refresh session mode, and the Bootloader is responsible for the subsequent steps of vehicle upgrading, namely, the Bootloader program executes extraction and decompression of the upgrade package, erases the module to be upgraded, and writes the decompressed upgrade package into the module to be upgraded so as to complete upgrading of the module to be upgraded.
Therefore, the Bootloader only executes the processes of data writing, data verification, logistics writing and the like in the vehicle upgrading process, the processes of target data erasing, data transmission and the like are executed by the application program, so that the transmission of the upgrading packet and the writing of the upgrading packet are executed by different programs in different vehicle modes, the vehicle upgrading time in the upgrading mode state is reduced, and the vehicle upgrading efficiency is improved.
