Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.
One of The core ideas of The embodiment of The present invention is to provide a system architecture scheme compatible with a vehicle system architecture and simultaneously satisfying a system architecture of rapid vehicle software upgrade (including OTA, Over The Air Technology, i.e., an Over-The-Air system upgrade Technology or an Over-The-Air download Technology), i.e., a Central Gateway (CGW) architecture, implementing a strategy for completing upgrade of vehicle software in multiple paths in parallel, so as to satisfy a rapid, efficient and stable vehicle software upgrade method.
Referring to fig. 1, a schematic architecture diagram of a vehicle upgrade architecture in an embodiment of the present invention is shown, which relates to an upper computer, a central gateway CGW, and a plurality of communication channels for performing online upgrade, where the plurality of communication channels may be connected to the upper computer through the central gateway, respectively.
Specifically, the vehicle upgrade architecture is mainly based on a current single system architecture upgraded one by ECU, and is realized by a diagnosis and write-through design of a lower computer development (Bootloader) related to the ECU, a vehicle network topology formulation and a central gateway software development, and a TCP/IP-based DoIP (Diagnostic communication over Internet Protocol, which performs diagnosis and communication through a network Protocol and performs remote vehicle diagnosis through TCP/IP and ethernet). Namely, a strategy for upgrading multi-path ECU parallel software is completed by a communication mode based on TCP/IP and designing a plurality of network channels and a multi-socket multithreading technology.
In a specific implementation, a solid update On the ECU can be usually realized through an On Board Diagnostics (On Board Diagnostics) interface of the vehicle, or a remote upgrade refresh of a corresponding ECU of the vehicle is realized through an OTA technology, so that the involved upper computer for online upgrade can include a vehicle diagnostic apparatus and an OTA client (i.e., OTA client (+ 4G)).
The vehicle diagnostic instrument can be an upper computer (namely a PC (personal computer) end) for locally upgrading a vehicle on line, and can interact with a cloud server; the OTA client (+4G) has similar functions with the vehicle diagnostic instrument and also belongs to a vehicle local upper computer (which can be embedded in a central gateway architecture); the central gateway CGW can be used for connecting the routing devices of all the ECUs to realize the physical and protocol access of the data channels between the vehicle diagnostic instrument/OTA client and all the channel ECUs; while multiple communication channels can be used to identify the channels on which different ECUs are located.
In the embodiment of the invention, the vehicle diagnostic apparatus/OTA client performs channel connection based on the framework shown in figure 1 when each ECU is upgraded, because of physical isolation among channels, mutual message and instruction interference does not exist when each ECU is upgraded, and the vehicle diagnostic apparatus/OTA client and CGW support multiple sockets to complete independent and parallel writing logic (multithreading mode) of each channel.
Referring to fig. 2, a flowchart of steps of a vehicle upgrade method in the embodiment of the present invention is shown, where based on a preset vehicle upgrade architecture, the preset vehicle upgrade architecture includes an upper computer for performing online upgrade, a central gateway, and a plurality of communication channels, where the plurality of communication channels are respectively connected to the upper computer through the central gateway, and specifically may include the following steps:
in an embodiment of the present invention, the upper computer may refer to a PC terminal for performing local online upgrade on a vehicle, and may interact with the cloud server and perform a series of operations, such as obtaining an upgrade ECU list of the vehicle, confirming an upgrade sequence, performing an upgrade action, feeding back an upgrade result, and the like.
Under the condition of the vehicle upgrading architecture, the upper computer can firstly acquire an ECU list to be upgraded of the vehicle to be upgraded, wherein the acquired ECU list to be upgraded can comprise a plurality of ECUs to be upgraded.
in practical application, the central gateway CGW may be used to connect each ECU, and may connect a plurality of communication channels with the upper computer, that is, the central gateway may be used as an intermediate communication structure, and communication connection between the upper computer and each ECU is realized through the plurality of communication channels.
At this time, after the host computer obtains the list of the ECUs to be upgraded, the communication channel corresponding to each ECU to be upgraded in the list can be determined, so that the ECU to be upgraded located in the communication channel can be upgraded according to the communication channel as a unit.
And 203, upgrading the ECUs to be upgraded in parallel through the corresponding communication channels.
In an embodiment of the present invention, after determining the communication channel corresponding to the ECU to be upgraded, the ECU to be upgraded located in the communication channel may be upgraded in units of the communication channel, specifically, in order to increase the upgrade speed of the entire vehicle software, a mode of upgrading each communication channel one by one is not adopted, but a mode of upgrading a plurality of communication channels in parallel is adopted, that is, each ECU to be upgraded is upgraded in parallel through the corresponding communication channel.
In a preferred embodiment, when parallel software upgrading or OTA upgrading is carried out on the ECU to be upgraded, the whole vehicle needs to be powered on in the OTA upgrading process, and unnecessary electric energy consumption is easily caused. Whether the vehicle needs to be upgraded or not can be monitored, the preset electronic device arranged on the vehicle is controlled to be in a closed state in the process of installing software, and specifically, the IO port corresponding to the preset electronic device can be controlled to be closed, so that the IO port stops transmitting electric energy to the preset electronic device.
It should be noted that the preset electronic device may be an electronic device that is not necessarily turned on after the vehicle is powered on, and may be determined according to actual conditions. For example, after the vehicle is powered on, electronic devices such as a wiper, a lamp, a vehicle air conditioner, and a vehicle sound box do not need to be turned on, and the electronic devices such as the wiper, the lamp, the vehicle air conditioner, and the vehicle sound box are electronic devices that do not need to be turned on. The embodiments of the present invention are not limited thereto.
In the embodiment of the invention, the vehicle to be upgraded is upgraded based on a vehicle upgrading framework, the vehicle upgrading framework can comprise an upper computer, a central gateway and a plurality of communication channels, the upper computer is used for performing online upgrading, the plurality of communication channels can be respectively connected with the upper computer through the central gateway, specifically, based on the framework, the communication channels corresponding to the ECUs to be upgraded are determined through an ECU list of the vehicle to be upgraded, and the ECUs to be upgraded are upgraded in parallel through the determined corresponding communication channels. The upgrading strategy of the multi-path ECU parallel software is completed based on a plurality of communication channels, the whole vehicle software upgrading speed is improved, the software upgrading success rate is improved and the vehicle power consumption is reduced by shortening the vehicle software upgrading time, and unnecessary upgrading waiting time is reduced so as to improve the user satisfaction.
Referring to fig. 3, a flowchart of steps of another vehicle upgrading method in the embodiment of the present invention is shown, where based on a preset vehicle upgrading architecture, the preset vehicle upgrading architecture includes an upper computer for performing online upgrading, a central gateway, and a plurality of communication channels, where the plurality of communication channels are respectively connected to the upper computer through the central gateway, and specifically may include the following steps:
in an embodiment of the present invention, the upper computer for performing online upgrade may interact with the cloud server, and perform a series of operations, such as obtaining an upgrade ECU list of a vehicle, confirming an upgrade sequence, performing an upgrade action, feeding back an upgrade result, and the like.
Specifically, the upper computer can obtain an ECU list to be upgraded of the vehicle to be upgraded from the cloud server.
In practical application, the upper computer can generate an upgrading request for a vehicle to be upgraded and send the upgrading request to the cloud server, and at the moment, the cloud server can respond to the received upgrading request and acquire an ECU list to be upgraded corresponding to the vehicle to be upgraded from a preset storage space; the cloud server sends the acquired ECU list to be upgraded to the upper computer, so that the upper computer can receive the ECU list to be upgraded sent by the cloud server.
In a preferred embodiment, the cloud server may receive, in advance, related information for the entire vehicle ECU sent by the vehicle terminal and store the information in a preset storage space, and when the server receives an upgrade request, the server may obtain corresponding ECU information according to an ECU identifier included in the upgrade request.
in practical application, the ECU list to be upgraded acquired from the cloud server may include target software version information of the ECU to be upgraded, an upgrade mode of the ECU to be upgraded, and an upgrade sequence of the ECU to be upgraded.
In an embodiment of the present invention, the ECUs to be upgraded may be sorted according to an upgrading order of the ECUs to be upgraded, and then communication channels may be allocated to the sorted ECUs to be upgraded, so as to determine the communication channels corresponding to the ECUs to be upgraded, where one communication channel corresponds to one ECU to be upgraded, that is, only one ECU to be upgraded may be upgraded while one communication channel is set.
The upgrading sequence of the ECU to be upgraded can be the sequence of the ECU-A, ECU-B, ECU-C, the sequence can be set as required, specifically can be set by an SOTA/FOTA cloud, the vehicle diagnostic instrument can be sorted based on a configuration file of a server, and the upgrading sequence of the three-electricity-related ECUs can be sorted to the end, namely, the ECUs related to the three-electricity in the ECU to be upgraded are upgraded at last.
303, carrying out parallel upgrading on each ECU to be upgraded;
in the embodiment of the invention, the ECU to be upgraded can be upgraded in parallel through the corresponding communication channel, so that the problem that the software upgrading of only one ECU can be completed at the same time due to single upgrading one by one, and the software upgrading of a plurality of ECUs cannot be completed in parallel to limit the software upgrading efficiency of the vehicle is avoided.
In specific implementation, the channel occupancy rates of a plurality of communication channels can be acquired in the process of upgrading each ECU to be upgraded; and when the channel occupancy rate reaches a preset threshold value, finishing the parallel upgrading of each ECU to be upgraded. The method can ensure that the channel occupancy rate of each communication channel is 100% in the ECU upgrading process until all ECUs of the current channel are upgraded, and parallel upgrading of the ECUs of each communication channel is realized.
And step 304, after upgrading of each ECU to be upgraded is completed, exiting the upgrading operation.
In one embodiment of the invention, parallel upgrading is performed on each ECU to be upgraded by taking the communication channel as a unit, and after the upgrading is completed, the upgrading operation can be quitted.
There may be several ECUs for parallel software upgrading, and the method of determining complete software upgrading may be realized through reading back the software version information of the ECUs.
Specifically, the current software version information of the to-be-upgraded ECU subjected to upgrading can be acquired, and whether the current software version information is the same as the target software version information in the list of the to-be-upgraded ECU is judged; in one case, if the current software version information is the same as the target software version information, the ECU to be upgraded can be judged to be successfully upgraded; in another case, if the current software version information is different from the target software version information, it may be determined that the ECU to be upgraded fails to be upgraded, that is, the ECU to be upgraded is not upgraded and cannot exit the upgrading operation.
It should be noted that, in the process of upgrading each ECU to be upgraded by using the communication channel as a unit, the situation that the strategies to be upgraded for different ECUs may be different may occur, and in this situation, an OEM (Original Equipment Manufacturer) may make a uniform upgrade specification to reduce the difficulty of upper computer development; if the upgrading strategy relates to interdependency among the ECUs, the upgrading sequence can be determined based on different dependencies when the ECU upgrading sequence is determined; in the embodiment of the invention, generally, the ECUs of different channels have no possibility of mutual dependency theoretically, and the upgrading dependency between the ECUs of different channels is generally avoided in the design of a preset vehicle upgrading architecture.
In the embodiment of the invention, the upgrading strategy of the multi-path ECU parallel software is completed based on a plurality of communication channels, the whole vehicle software upgrading speed is increased, and the problem of low upgrading success rate caused by the change of the external environment or the internal environment of the vehicle is greatly improved by shortening the vehicle software upgrading time, so that the software upgrading success rate is increased; and for the electric vehicle, the vehicle software upgrading time may influence the vehicle power consumption, so that the vehicle power consumption caused by the vehicle software upgrading is reduced by shortening the vehicle software upgrading time; moreover, the experience of vehicle software upgrading of customers can be improved, unnecessary upgrading waiting time is reduced, and the purpose of improving the satisfaction degree of users is achieved.
