In order to explain the technical means of the present invention, the following description will be given by way of specific examples.
Referring to fig. 1, a schematic flowchart of a software updating method for a vehicle electronic product according to an embodiment of the present invention is provided. As shown in fig. 1, the software updating method of the vehicle electronic product may include the steps of:
step S101: the upper computer obtains the update files of a plurality of electronic products to be updated on the vehicle, analyzes the update files of each electronic product to be updated and sends the analyzed update files to the device.
In the embodiment of the present invention, the upper computer refers to a terminal device capable of sending an operation command, which includes but is not limited to a mobile terminal such as a notebook computer and a mobile phone, and the update file refers to update data required by the electronic product to be updated when the software of the electronic product to be updated is updated.
During specific implementation, the upper computer can acquire the update files of the electronic products to be updated on the vehicle, which are stored in the external storage device, through the data line, and can also read the update files of the electronic products to be updated on the vehicle, which are stored in the memory of the upper computer in advance; the external storage device includes, but is not limited to, a device with a storage function, such as a usb disk, a removable hard disk, and a magneto-optical disk.
In addition, the host computer is connected with the updating device through a USB data line. After the upper computer obtains the update files of a plurality of electronic products to be updated on the vehicle, the upper computer can analyze the obtained update files and send the analyzed update files to the updating device through the USB data line.
Further, as a preferred embodiment of the present invention, the acquiring, by the upper computer, the update files of a plurality of electronic products to be updated on the vehicle, and sending the update files of each electronic product to be updated to the updating apparatus after analyzing the update files includes:
obtaining baud rates of a plurality of sub-networks on the vehicle and update files of a plurality of electronic products to be updated in the sub-networks;
setting the baud rate of a controller corresponding to the sub-network in the updating device according to the obtained baud rate of the sub-network;
acquiring the number N of controllers in the updating device, and creating N threads according to the number N, so that the N threads can read the updating files of a plurality of electronic products to be updated in the sub-networks corresponding to the N threads, analyze the updating files and send the analyzed updating files to the corresponding controllers; wherein N is an integer greater than zero.
In the embodiment of the invention, the whole vehicle comprises a plurality of sub-networks, and each sub-network is connected with the vehicle CAN bus to form the vehicle CAN network. Furthermore, each sub-network is connected by a pair of CAN-bus and OBD-interface and each sub-network comprises a plurality of electronic products to be updated.
Furthermore, because the updating device comprises a plurality of controllers, and one controller corresponds to one sub-network, the upper computer needs to acquire baud rates of the plurality of sub-networks, and sets the baud rate of the controller corresponding to the sub-network in the updating device to be the same as that of the sub-network according to the acquired baud rate of the sub-network, so that the sub-network and the corresponding controller have the same speed when data is transmitted; the baud rate of a sub-network refers to the rate at which the sub-network transmits data.
After the upper computer sets the baud rate of the controller corresponding to the sub-network in the updating device according to the baud rate of the sub-network, the upper computer can import the updating files of the electronic products to be updated in each sub-network into a designated path, detect the number N of the controllers in the updating device, and create N threads according to the number N, wherein the N threads are in one-to-one correspondence with the N controllers, namely the threads, the controllers and the sub-networks are in one-to-one correspondence.
After the upper computer creates the N threads, each sub-network has identification information representing the identity of each sub-network, so that each thread can simultaneously read the update files of a plurality of electronic products to be updated in the sub-network corresponding to the thread, analyze the read update files, and send data to the corresponding controllers through established protocols after the update files are analyzed.
For example, assuming that three sub-networks, namely sub-network 1, sub-network 2 and sub-network 3, are included in the entire vehicle CAN network, and each sub-network includes a plurality of electronic products to be updated, the number of controllers in the updating apparatus is also 3, that is, the updating apparatus includes controller 1, controller 2 and controller 3, and sub-network 1 corresponds to controller 1, sub-network 2 corresponds to controller 2, and sub-network 3 corresponds to controller 3.
When the upper computer detects an updating operation triggered by a user, the upper computer acquires the baud rates of the sub-networks 1, 2 and 3, for example, the acquired baud rates of the three sub-networks are 125Kbps for the sub-network 1, 250Kbps for the sub-network 2 and 500Kbps for the sub-network 3 respectively. Meanwhile, the upper computer also acquires the update files of a plurality of products to be updated in the sub-networks 1, 2 and 3.
After the upper computer obtains the baud rates of the sub-networks 1, 2 and 3, the upper computer sets the baud rate of the controller 1 to 125Kbps, sets the baud rate of the controller 2 to 250Kbps and sets the baud rate of the controller 3 to 500Kbps, so that the baud rates of the sub-networks and the corresponding controllers are the same.
After the upper computer sets the baud rate of the controller, the upper computer establishes corresponding threads according to the number of the controllers, namely the upper computer establishes three threads which are respectively a thread 1, a thread 2 and a thread 3, wherein the thread 1 corresponds to the controller 1, the thread 2 corresponds to the controller 2, and the thread 3 corresponds to the controller 3.
Then, the thread 1 reads the update files of the electronic products to be updated in the corresponding sub-network 1, and sends the update files to the controller 1 through the established sending protocol after analyzing the update files, similarly, the thread 2 reads the update files of the electronic products to be updated in the corresponding sub-network 2, and sends the update files to the controller 2 through the established sending protocol after analyzing the update files, and the thread 3 reads the update files of the electronic products to be updated in the corresponding sub-network 3, and sends the update files to the controller 3 through the established sending protocol after analyzing the update files.
In this embodiment, the upper computer establishes the multiple threads, so that the multiple threads simultaneously read the update files of the multiple electronic products to be updated in each subnet, and the update files are analyzed and then sent to the corresponding controllers, thereby greatly shortening the time for reading, analyzing and sending the data of the vehicle electronic products in the software updating process, and further saving the updating time and the updating cost of the vehicle electronic products.

Through this OBD interface, the update unit can be with a plurality of electronic product that wait to update on the vehicle carry out the communication.
During specific implementation, the updating device sends the updated file to the OBD interface through the vehicle diagnosis line after receiving the analyzed updated file sent by the upper computer, and then transmits the updated file to a plurality of electronic products to be updated on the vehicle through the ODB interface.
When a plurality of electronic products to be updated on the vehicle receive the update files sent by the updating device, the electronic products to be updated write the respective update files into the flash memories of the electronic products to be updated, and after the writing is finished, the software of the electronic products to be updated is updated according to the written update files.
Further, as a preferred embodiment of the present invention, the updating apparatus includes a plurality of controllers, and the updating apparatus sends the update file to the corresponding electronic product to be updated through the diagnostic interface includes:
the plurality of controllers receive the analyzed update files sent by the threads corresponding to the controllers respectively, and send the update files to the electronic products to be updated in the sub-networks corresponding to the controllers respectively through the diagnosis interfaces.
In the embodiment of the invention, each controller in the updating device is connected with the OBD interface, and can transmit data to the plurality of electronic products to be updated in the corresponding sub-network through the OBD interface.
For example, after receiving the analyzed update file sent by the thread 1, the controller 1 sends the analyzed update file to the electronic product to be updated in the sub-network 1 through the ODB interface; after receiving the analyzed update file sent by the thread 2, the controller 2 sends the analyzed update file to the electronic product to be updated in the sub-network 2 through the ODB interface; after receiving the analyzed update file sent by the thread 3, the controller 3 sends the analyzed update file to the electronic product to be updated in the sub-network 3 through the ODB interface.
In this embodiment, the plurality of controllers in the update device simultaneously receive the analyzed update file sent by the respective corresponding threads, and send the received file to the electronic product to be updated in the respective corresponding sub-networks through the OBD interface, so that the plurality of electronic products to be updated simultaneously perform software update, thereby saving the update time and the update cost of the vehicle electronic product.
Further, as a preferred embodiment of the present invention, the software updating method further includes:

In the embodiment of the present invention, because the updating device includes a plurality of controllers, and one controller corresponds to one sub-network, the upper computer needs to acquire baud rates of the plurality of sub-networks, and sets the baud rate of the controller corresponding to the sub-network in the updating device to be the same as that of the sub-network according to the acquired baud rate of the sub-network, so as to realize that the rates of the sub-network and the corresponding controller are the same when data is transmitted; the baud rate of a sub-network refers to the rate at which the sub-network transmits data.
