It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
In order to solve the problems of slow data processing efficiency and large workload of an MCU (micro control unit) in a TBOX (vehicle networking system) or an AVNT (vehicle on board) in the conventional online upgrade technology, in one embodiment, as shown in fig. 1, a vehicle-mounted upgrade communication module is provided, which includes a communication module 110 and a gateway 120;
the communication module 110 is configured to receive the software upgrade data packet and forward the software upgrade data packet to the gateway 120;
the gateway 120 is configured to send the software upgrading data packet to the vehicle-mounted module 130 to be upgraded.
The communication module is used for realizing communication between the vehicle and the remote server, namely the vehicle obtains the software upgrading package from the remote server through the communication module.
The gateway is used for receiving the software upgrading data packet from the communication module and sending the software upgrading data packet to the vehicle-mounted module to be upgraded. The on-board module may be an ECU (Electronic Control Unit) or a GPS (Global Positioning System) module on the vehicle. In one example, in order to keep the software of the vehicle-mounted module on the vehicle in the latest version state, when the remote server monitors that the software of the vehicle-mounted module on the vehicle needs to be upgraded, the remote server actively sends a software upgrading data packet to the communication module to the gateway, the gateway issues the software upgrading data packet to the vehicle-mounted module to be upgraded, and the vehicle-mounted module to be upgraded executes the software upgrading data packet to complete the upgrading of the software of the vehicle-mounted module to be upgraded. In yet another example, the gateway on the vehicle actively queries the remote server through the communication module whether new versions of software exist, and if so, the remote server sends a software upgrade data packet to the gateway through the communication module. Further, the gateway can issue a software upgrading data packet to the corresponding vehicle-mounted module to be upgraded according to the physical address.
Based on the above, the process of upgrading the software of the vehicle-mounted module to be upgraded is as follows: the communication module obtains the software upgrading data packet from a remote server in communication connection with the communication module, forwards the software upgrading data packet to the gateway, then transmits the software upgrading data packet to the vehicle-mounted module to be upgraded by the gateway, and the vehicle-mounted module to be upgraded executes the software upgrading data packet to complete self software upgrading.
In each embodiment of the vehicle-mounted upgrading communication module, the communication module directly forwards the received software upgrading data packet to the gateway, and the gateway sends the software upgrading data packet to the vehicle-mounted module to be upgraded, so that the software upgrading data packet is prevented from being processed by the TBOX or the AVNT and then forwarded to the gateway for processing, the data processing efficiency in the upgrading process of the vehicle-mounted module to be upgraded is improved, the workload of the TBOX or the AVNT is reduced, and the performance of a vehicle is improved.
In one embodiment, as shown in fig. 2, an online vehicle upgrade apparatus is provided, which includes a service processing apparatus 140, an on-board module 150, and an on-board upgrade communication module according to an embodiment of the on-board upgrade communication module;

The vehicle refers to a transportation tool used for riding instead of walk by people, and can be an automobile, an intelligent bicycle, a balance scooter and the like.
The service processing means may be configured to process service requests sent by the remote server, the service requests including an upgrade connection request, a remote emergency call service request, and the like. In one example, the service processing device is TBOX or AVNT. It should be noted that TBOX is a vehicle-mounted terminal device installed on an instrument desk of a vehicle to acquire, store and send information of all working conditions of the vehicle, and has a real-time live-action function, and can interact with a user and the outside by using a mobile network. AVNT refers to a vehicle-mounted infotainment device installed on a vehicle, which enables interaction between the vehicle and a user, and between the vehicle and the outside, and at least one of TBOX and AVNT is currently installed on the vehicle. Further, the service processing device is also connected to the on-board module, and in an example, the on-board module may be connected to the service processing device through a CAN (Controller Area Network) bus.
The communication module is used for realizing communication between the service processing device or the gateway on the vehicle and the remote server. In one example, the communication module may be provided independently of the service processing apparatus, and the communication module is connected to an MCU in the service processing apparatus. In another example, the communication module may also be built in the service processing device and connected with the MCU of the service processing device.
In a specific embodiment, as shown in fig. 3, the service processing device 140 includes a first micro control unit 142 and a first ethernet chip 144; the gateway 120 includes a second ethernet chip 122 and a second micro control unit 124;
the communication module 110 is connected to the first micro control unit 142 and the first ethernet chip 144 respectively; the first micro control unit 142 is connected with the vehicle-mounted module 150;
the second ethernet chip 124 is connected to the first ethernet chip 144, the second mcu 122 and the vehicle module 150, respectively.
The first micro control unit and the second micro control unit can be used for processing data, and the first Ethernet chip and the second Ethernet chip are used for providing Ethernet interfaces, namely the communication module is connected with the gateway through the Ethernet interfaces, and the gateway is connected with the vehicle-mounted module through the Ethernet interfaces. The communication module, the gateway and the vehicle-mounted module are connected by the Ethernet interface, so that the data transmission rate is improved, and the time for upgrading the vehicle-mounted module to be upgraded is shortened.
In one example, the communication module and the first micro control unit, and the vehicle-mounted module and the first micro control unit CAN be connected through a CAN bus. Further, the gateway also comprises a memory, and the memory is connected with the second micro control unit. In yet another embodiment, the communication module may be a 4G communication module.
In each embodiment of the vehicle online upgrading device, the remote server directly sends the software upgrading data packet to the gateway through the communication module, and the gateway sends the software upgrading data packet to the vehicle-mounted module to be upgraded, so that the software upgrading of the vehicle-mounted module to be upgraded is completed, and the software upgrading data packet is prevented from being sent to the gateway after being sent to the service processing device for processing, thereby accelerating the data processing efficiency and reducing the workload of a vehicle networking system or a vehicle machine.
In one embodiment, as shown in fig. 4, there is provided a vehicle online upgrade system, comprising a remote server 160, and an on-board online upgrade apparatus as described above;
the remote server 160 is connected to the communication module 110.
The remote server is used for providing services for the vehicle, and the services comprise software upgrading services, remote emergency call services and the like. In one example, the communication module is coupled to a remote server that provides a variety of services to the vehicle including software upgrade services, remote emergency call services, and the like. In yet another example, the communication module connects a plurality of remote servers, each of which may provide a service, for example, where one remote server provides a software upgrade service and another remote server provides a remote emergency call service.
In order to further explain the scheme of each embodiment of the vehicle online upgrade system, the implementation process of each embodiment of the invention is specifically described by taking the upgrade process of the vehicle online upgrade system as an example in practical application:
in a specific embodiment, the communication module receives a connection request sent by a remote server and judges whether the connection request is an upgrade connection request; if so, sending a mark upgrading connection request obtained by marking the connection request to the gateway;
and the gateway establishes a communication channel for receiving the software upgrading data packet with the remote server through the communication module according to the label upgrading connection request.
Further, the communication module receives a connection request sent by the remote server and judges whether the connection request is an upgrade connection request; if not, the connection request is forwarded to the service processing device.
The remote server is a calling party, the vehicle is a called party, in other words, when the remote server monitors that the vehicle needs to be served, the remote server actively sends a service request to the vehicle, and when the vehicle receives the service request, the vehicle responds to the service request and then establishes communication connection with the remote server.
And when the communication module judges that the received connection request is an upgrading connection request, the communication module marks the upgrading connection request to obtain a marked upgrading connection request and sends the marked upgrading connection request to the gateway. The gateway can recognize the connection request sent by the communication module for upgrading according to the mark. In one example, the token may employ a specific IP, a specific Socket, or other pre-designed token. The gateway establishes a communication channel of the remote server, the communication module and the gateway through handshake communication between the communication module and the remote server according to the label upgrading connection request, and the remote server directly sends a software upgrading data packet to the gateway based on the communication channel.
When the communication module judges that the received connection request is a non-upgrade connection request (including a remote control connection request or a remote emergency call service, etc.), the connection request is forwarded to the service processing device. Specifically, the service processing device establishes a control connection with the remote server through the communication module according to the remote control connection request. The service processing device establishes a session connection with a remote server through the communication module according to the remote emergency call service.
The communication module is used for distinguishing an upgrading connection request and a non-connection request sent by a remote server, the upgrading connection request is sent to the gateway, and the non-upgrading connection request is sent to the service processing device. Therefore, the connection request sent by the remote server is shunted, the upgraded connection request is directly sent to the gateway, the non-upgraded connection request is directly sent to the service processing device, the workload of the MCU in the service processing device is reduced, the secondary processing of data is avoided, the processing speed of the connection request sent by the remote server is increased, and the data transmission rate is also increased, so that the work efficiency of the vehicle online upgrading system is increased, and the time of a user is saved.
In another specific embodiment, the communication receives a connection request sent by a remote server and forwards the connection request to the gateway;
the gateway judges whether the connection request is an upgrading connection request, and if so, a communication channel which is established with a remote server through a communication module and used for receiving a software upgrading data packet is established according to the connection request.
Further, the communication receives a connection request sent by the remote server, and forwards the connection request to the service processing device;
the service processing device judges whether the connection request is an upgrading connection request or not, and if so, discards the connection request.
The communication module receives a connection request sent by a remote server and forwards the connection request to the service processing device and the gateway at the same time. In one example, the communication module may copy the connection request in one copy using a copy technique. Further, the backup data of the connection request may be sent to the service processing apparatus, and the original data of the connection request may be sent to the gateway.
The gateway judges whether the connection request is an upgrading connection request, if so, the gateway establishes a communication channel with the remote server through the communication module according to the upgrading connection request, and if not, the gateway discards the connection request.
And the service processing device judges whether the connection request is an upgrading connection request or not, if so, the service processing device discards the connection request, and if not, the service processing device establishes corresponding connection with the remote server according to the connection request.
The communication module directly forwards the connection request sent by the remote server to the gateway and the service processing device at the same time, and the gateway and the service processing device respectively judge whether the connection request is an upgrading connection request and execute corresponding actions according to the judgment result. Therefore, the repeated processing of the upgrading connection request and the software upgrading data packet to the gateway through the service processing device is avoided, the upgrading efficiency of the vehicle-mounted module to be upgraded is improved, and the serial mode of processing the data sent by the remote server by the vehicle in the traditional technology is changed.
Further, the gateway disconnects the communication channel when confirming that the vehicle-mounted module to be upgraded receives the software upgrading data packet.
In one example, the gateway determines that all the software upgrading data packets are sent to the vehicle-mounted module to be upgraded, that is, determines that the vehicle-mounted module to be upgraded receives the software upgrading data packets. In one example, the software upgrading data package includes a numerical value describing the size of the software upgrading data package, and when the size of data transmitted when the gateway transmits the software upgrading data package is equal to the numerical value, it is determined that the gateway transmits all the software upgrading data packages to the vehicle-mounted module to be upgraded. In another example, after the vehicle-mounted module to be upgraded completely receives the software upgrading data packet sent by the gateway, a reception completion notification is fed back to the gateway, and the gateway confirms that the vehicle-mounted module to be upgraded receives the software upgrading data packet according to the reception completion notification.
After the gateway confirms that the vehicle-mounted module receives the software upgrading data packet, the gateway informs the communication module to disconnect a communication channel of the remote server, the communication module and the gateway and restore the link to the default link of the remote server, the communication module and the service processing device. Thereby ensuring that the remote server can provide common services for the vehicle in real time.
In each embodiment of the vehicle online upgrading system, the upgrading connection request and the non-upgrading connection request are shunted through the communication module, or the connection request is simultaneously forwarded to the gateway and the service processing device through the communication module, so that the gateway and the service processing device can judge autonomously, the data processing efficiency related to upgrading, including the upgrading connection request, the software upgrading data packet and the like, is improved, and the workload of the service processing device is reduced.
The vehicle upgrading method provided by the application can be applied to application environments shown in fig. 1 to 4. The remote server may be implemented by a stand-alone server or a server cluster composed of a plurality of servers.
In one embodiment, as shown in FIG. 5, a vehicle upgrade method is provided. Taking the application of the method to the communication module in fig. 1 as an example, the method includes the following steps:
step S510, the communication module receives the software upgrading data packet and issues the software upgrading data packet to the vehicle-mounted module to be upgraded through the gateway.
The software upgrading data packet is used for upgrading software of the vehicle-mounted module to be upgraded so as to ensure that the software of each vehicle-mounted module of the vehicle can be in the latest state.
After receiving the software upgrading data packet sent by the remote server, the communication module directly sends the software upgrading data packet to the gateway, and then the gateway sends the software upgrading data packet to the vehicle-mounted module to be upgraded.
In a specific embodiment, as shown in fig. 6, before the step of receiving the software upgrade data package by the communication module, the method further includes:
the communication module receives a connection request sent by a remote server, judges whether the connection request is an upgrading connection request or not, and sends a marked upgrading connection request obtained by marking the connection request to a gateway if the connection request is the upgrading connection request;
further, if not, the connection request is sent to the service processing device.
The communication module receives a connection request actively sent by the remote server, and when the communication module judges that the connection request is an upgrading connection request, the communication module marks the upgrading connection request to obtain a marked upgrading connection request and forwards the marked upgrading connection request to the gateway so as to instruct the gateway to establish a communication channel of the remote server, the communication module and the gateway.
And when the communication module judges that the connection request is a non-upgrading connection request, the communication module sends the connection request to the service processing device.
In another specific embodiment, before the step of receiving the software upgrade data package by the communication module, the method further includes:
the communication module receives a connection request sent by a remote server and forwards the connection request to a gateway; the connection request is used for indicating the gateway to judge whether the connection request is an upgrading connection request, and when the judgment result is yes, a communication channel which is established with the remote server through the communication module and is used for receiving the software upgrading data packet is established.
Further, the communication module forwards the connection request to the service processing device, and the service processing device judges whether the connection request is an upgrade connection request, and if so, discards the connection request.
The communication module sends the connection request sent by the remote server to the gateway and the service processing device at the same time, so that the gateway and the service processing device autonomously judge whether to perform corresponding action on the connection request, and secondary authentication and secondary encryption and decryption processing of data are avoided.
According to the vehicle upgrading method, the communication module directly issues the received software upgrading data packet to the vehicle-mounted module to be upgraded through the gateway, so that the online upgrading of the vehicle-mounted module to be upgraded is realized, the data transmission efficiency is improved, and the problem that the software upgrading data packet is transferred to the gateway after being processed by the service processing device in the prior art is avoided, so that the workload of the service processing device is reduced, and the data transmission and processing efficiency is improved.
In one embodiment, as shown in FIG. 7, a vehicle upgrade method is provided. Taking the gateway in fig. 4 as an example, the method includes the following steps:
step S710, the gateway receives the software upgrading data packet sent by the communication module and sends the software upgrading data packet to the vehicle-mounted module to be upgraded.
The gateway directly obtains the software upgrading data packet sent by the remote server through the communication module, and then the gateway sends the software upgrading data packet to the vehicle-mounted module to be upgraded, so that the gateway can obtain data more quickly.
In a specific embodiment, as shown in fig. 8, before the step of receiving, by the gateway, the software upgrade data packet sent by the communication module, the method further includes:
step S810, the gateway receives a mark upgrading connection request sent by the communication module; the upgrade connection request is marked by the communication module; the connection request is sent by a remote server;
and step S820, the gateway establishes a communication channel for receiving the software upgrading data packet with the remote server through the communication module according to the label upgrading connection request.
The gateway receives the tag upgrade connection request, and recognizes the tag upgrade connection request as an upgrade connection request according to a tag (a specific IP, a specific Socket, or another designed tag) attached to the tag upgrade connection request.
Further, after the step of receiving, by the gateway, the tag upgrade connection request sent by the communication module, the method further includes:
the gateway verifies the validity of the label upgrading connection request and establishes a communication channel when the verification is passed.
It should be noted that, the gateway performs validity verification on the upgrade connection request, and if the upgrade connection request is valid, a communication channel is established according to the upgrade connection request; if the connection request is illegal, the label upgrading connection request is discarded, and the initial state is returned. The initial state refers to the state that the communication channel of the remote server-communication module-gateway is disconnected, and the connection state of the remote server-communication module-service processing device is maintained. In one example, the token upgrade connection request is validated using an asymmetric algorithm. The asymmetric algorithm means that an encryption key and a decryption key of one encryption algorithm are different, and this embodiment does not exclude other validity verification algorithms. After receiving the mark upgrading connection request, the gateway carries out validity verification on the mark upgrading connection request, and only after the verification is passed, a communication channel is established, so that the safety of vehicle online upgrading is ensured, and illegal invasion such as viruses is avoided.
In a specific embodiment, as shown in fig. 9, before the step of receiving, by the gateway, the software upgrade data packet sent by the communication module, the method further includes:
the gateway receives a connection request sent by a remote server through a communication module;
the gateway judges whether the connection request is an upgrading connection request, and if so, a communication channel which is established with a remote server through a communication module and used for receiving a software upgrading data packet is established according to the connection request. Further, if not, the connection request is discarded.
Further, as shown in fig. 10, after the step of receiving, by the gateway, the connection request sent by the remote server through the communication module, the method further includes:
the gateway verifies the validity of the connection request and judges whether the connection request is an upgrading connection request or not when the verification is passed.
Wherein, in one example, the gateway uses RSA algorithm to validate the copied data. After receiving the copied data, the gateway verifies the legality of the copied data, and only after the copied data passes the verification, a communication channel is established, so that the safety of online upgrading of the vehicle is ensured, and illegal invasion such as viruses is avoided.
In a specific embodiment, as shown in fig. 10, before the step of establishing the communication channel, the method further includes:
the gateway judges whether the current vehicle state meets the upgrading condition, if so, a communication channel is established; the current vehicle state includes a driving state, a battery state, and an on-board module state.
Before establishing the communication channel according to the upgrade connection request, the gateway needs to judge whether the vehicle state meets the upgrade condition, and if so, the communication channel is established according to the upgrade connection request. In one example, the vehicle state includes a driving state, a battery state, and an on-board module state. Specifically, when the driving state is a static state, the storage battery state is sufficient, and the vehicle-mounted module state is the vehicle-mounted module idle state, the gateway judges that the current vehicle state meets the upgrading condition. Before the communication channel is established, whether the vehicle state meets the upgrading condition is checked, and the communication channel is established only after the vehicle state meets the upgrading condition, so that the environment of online upgrading of the vehicle is ensured, and errors in online upgrading are avoided.
In a specific embodiment, as shown in fig. 11, before the step of issuing the software upgrade data packet to the vehicle-mounted module to be upgraded, the method includes:
