In order to better understand the technical scheme of the present invention, the following detailed description will refer to the accompanying drawings and specific embodiments.
The software package of the vehicle-mounted information entertainment system can be updated iteratively, and the downloading and the buffering of the full upgrade package have requirements on the memory space, for example, the size of the full upgrade package is 2.2G, and then the memory space with the size larger than 4.4G is required for the downloading and the buffering of the full upgrade package. The total memory of the TBOX of the vehicle is generally 8G, the residual memory of the TBOX is smaller than 4.4G, and the downloading and the buffering of the total upgrade package cannot be supported. If the TBOX supports downloading and buffering of the full upgrade package, the memory of the TBOX needs to be upgraded, which increases the hardware cost of the whole vehicle.
As shown in fig. 1, the method for upgrading the vehicle-mounted infotainment system applied to the vehicle-mounted infotainment system according to the embodiment includes:
step S1, receiving an upgrade task notification of a vehicle-mounted information entertainment system sent by a TBOX;
step S2, based on the upgrade task notification, downloading and storing a full upgrade package of the vehicle-mounted information entertainment system from the OTA cloud through a third DNN channel provided by the TBOX;
and step S3, upgrading the vehicle-mounted information entertainment system based on the full upgrade package.
Steps S1-S3 are performed by an OTA component implanted in the in-vehicle infotainment system.
In this embodiment, the TBOX provides a plurality of network channels, including a first DNN channel, a second DNN channel, and a third DNN channel, and the TBOX has already allocated a network segment corresponding to the second DNN channel to the vehicle-mounted infotainment system, so the vehicle-mounted infotainment system may already implement the internet surfing function through the second DNN channel provided by the TBOX.
In order to realize the function of surfing the internet through the third DNN channel, before step S1, the TBOX needs to allocate the network segment corresponding to the third DNN channel to the in-vehicle infotainment system. When the vehicle-mounted information entertainment system needs to be upgraded, the OTA cloud end can send the vehicle-mounted information entertainment system upgrading task to the TBOX through the third DNN channel, the TBOX can send the upgrading task notification of the vehicle-mounted information entertainment system to the vehicle-mounted information entertainment system through the internal interface after receiving the vehicle-mounted information entertainment system upgrading task notification, the vehicle-mounted information entertainment system can download the whole upgrading package of the vehicle-mounted information entertainment system from the OTA cloud end through the third DNN channel and store the whole upgrading package, and then the vehicle-mounted information entertainment system upgrading interface is called to upgrade the vehicle-mounted information entertainment system. The total memory of the vehicle-mounted information entertainment system is generally 16G, the residual memory is larger than 4.4G, and the residual memory space is large enough, so that the requirements of downloading and buffering of the full-volume upgrade package on the memory space can be met, the full-volume package upgrade of the vehicle-mounted information entertainment system can be realized, the memory of a TBOX (tunnel boring oxide) is not required to be upgraded to support the full-volume package upgrade, and the increase of the whole vehicle cost can be avoided. In addition, in the upgrading process of the vehicle-mounted information entertainment system, the upgrading progress is fed back to the TBOX through the Ethernet, and the TBOX reports the upgrading progress to the OTA cloud through the third DNN channel.
In this embodiment, in order to ensure the safety of the vehicle end and the cloud end, vehicle cloud verification is required before upgrading the vehicle-mounted information entertainment system each time, and the vehicle cloud verification is based on a PKI certificate. Therefore, before step S1, the method for upgrading the in-vehicle infotainment system further includes: the first DNN channel provided by the TBOX applies for a PKI certificate from a PKI server. Of course, in order to realize the function of surfing the internet of the vehicle-mounted infotainment system through the first DNN channel, before the vehicle-mounted infotainment system applies for the PKI certificate to the PKI server through the first DNN channel provided by the TBOX, the TBOX needs to allocate the network segment corresponding to the first DNN channel to the vehicle-mounted infotainment system. Besides the verification between the vehicle-mounted infotainment system and the cloud end, the verification between the TBOX and the cloud end is also required, so before step S1, the TBOX is required to apply the PKI certificate to the PKI server through the first DNN channel.
The TBOX is assigned to each network channel segment of the in-vehicle infotainment system as shown in fig. 2, and 172.16.104 is the corresponding network segment of the second DNN channel. The TBOX and the vehicle-mounted information entertainment system have perfect communication protocols, and after network segments corresponding to the network channels are distributed to the vehicle-mounted information entertainment system, the vehicle-mounted information entertainment system can surf the internet through the network channels.

The process of establishing the DoIP connection between the OTA component and the vehicle-mounted information entertainment system is as follows: the OTA component judges whether an OTA upgrading condition is met, if yes, an OTA mode is entered, a TBOX enters the OTA mode, and the vehicle-mounted information entertainment system opens a routing channel; the OTA component decompresses the full upgrade package of the vehicle-mounted information entertainment system; the OTA component judges whether the vehicle is powered on or not; if the vehicle is not powered on, the TBOX controls the vehicle to be powered on; if the vehicle is powered on, the OTA component waits for 60s; the vehicle-mounted information entertainment system sends the DoIP-Server service state of the vehicle-mounted information entertainment system to the TBOX, the TBOX sends the DoIP-Server service state of the vehicle-mounted information entertainment system to the OTA component, and the OTA component judges whether the DoIP-Server_vehicle-mounted information entertainment system is OK or not; resetting the vehicle-mounted information entertainment system if the state of the DoIP-Server_vehicle-mounted information entertainment system is not OK; if the state of the DoIP-Server_vehicle-mounted information entertainment system is OK, a TBOX DoIP initialization interface is called, the TBOX establishes a DoIP Socket, and the vehicle-mounted information entertainment system establishes the DoIP Socket; the OTA component judges whether the DoIP connection is successful or not; if the vehicle-mounted information entertainment system is successful, the vehicle-mounted information entertainment system enters a refreshing flow, if the vehicle-mounted information entertainment system is unsuccessful, the vehicle-mounted information entertainment system is reset.
The process of establishing DoIP connection between the OTA component and the APA\ICM is as follows: the OTA component judges whether an OTA upgrading condition is met, if yes, an OTA mode is entered, a TBOX enters the OTA mode, and the vehicle-mounted information entertainment system opens a routing channel; the OTA component decompresses the full upgrade package of the controller software; the OTA component judges whether the vehicle is powered on or not; if the vehicle is not powered on, the TBOX controls the vehicle to be powered on; if the vehicle is powered on, the OTA component waits for 60s; the APA/ICM sends the DoIP-Server service state of the APA/ICM to the TBOX, the TBOX sends the DoIP-Server service state of the APA/ICM to the OTA component, and the OTA component judges whether the DoIP-Server service state of the APA/ICM is OK or not; resetting the APA\ICM if the DoIP-Server service state of the APA\ICM is not OK; if the DoIP-Server service state of the APA\ICM is OK, the vehicle-mounted information entertainment system sends a route channel state to the TBOX, the TBOX sends the route channel state of the vehicle-mounted information entertainment system to the OTA component, the OTA component judges whether the route channel state of the vehicle-mounted information entertainment system is OK or not, if the route channel state of the vehicle-mounted information entertainment system is not OK, the vehicle-mounted information entertainment system is reset, if the route channel state of the vehicle-mounted information entertainment system is OK, a TBOX DoIP initializing interface is called, the TBOX establishes a DoIP Socket, and the APA\ICM establishes a DoIP Socket; the OTA component judges whether the DoIP connection is successful or not; if successful, the method enters a brushing flow, and if unsuccessful, APA\ICM OTA fails.
As shown in fig. 3, corresponding to the method for upgrading the vehicle-mounted infotainment system applied to the vehicle-mounted infotainment system, the embodiment further provides a device for upgrading the vehicle-mounted infotainment system applied to the vehicle-mounted infotainment system, where the device for upgrading the vehicle-mounted infotainment system may be an otainment system otam component, and includes:
the receiving module is used for receiving the upgrading task notification of the vehicle-mounted information entertainment system sent by the TBOX;
the downloading module is used for downloading and storing the full upgrade package of the vehicle-mounted information entertainment system from the OTA cloud through a third DNN channel provided by the TBOX based on the upgrade task notification;
and the upgrading module is used for upgrading the vehicle-mounted information entertainment system based on the full upgrading package.
In this embodiment, the TBOX provides a plurality of network channels, including a first DNN channel, a second DNN channel, and a third DNN channel, and the TBOX has already allocated a network segment corresponding to the second DNN channel to the vehicle-mounted infotainment system, so the vehicle-mounted infotainment system may already implement the internet surfing function through the second DNN channel provided by the TBOX.
In order to realize the function of surfing the Internet of the vehicle-mounted information entertainment system through the third DNN channel, the TBOX needs to distribute the network segment corresponding to the third DNN channel to the vehicle-mounted information entertainment system before the receiving module receives the upgrading task notification of the vehicle-mounted information entertainment system sent by the TBOX. When the vehicle-mounted information entertainment system needs to be upgraded, the OTA cloud end can send the vehicle-mounted information entertainment system upgrading task to the TBOX through the third DNN channel, the TBOX can send the upgrading task notification of the vehicle-mounted information entertainment system to the vehicle-mounted information entertainment system through the internal interface after receiving the vehicle-mounted information entertainment system upgrading task notification, the vehicle-mounted information entertainment system can download the whole upgrading package of the vehicle-mounted information entertainment system from the OTA cloud end through the third DNN channel and store the whole upgrading package, and then the vehicle-mounted information entertainment system upgrading interface is called to upgrade the vehicle-mounted information entertainment system. The total memory of the vehicle-mounted information entertainment system is generally 16G, the residual memory is larger than 4.4G, and the residual memory space is large enough, so that the requirements of downloading and buffering of the full-volume upgrade package on the memory space can be met, the full-volume package upgrade of the vehicle-mounted information entertainment system can be realized, the memory of a TBOX (tunnel boring oxide) is not required to be upgraded to support the full-volume package upgrade, and the increase of the whole vehicle cost can be avoided. In addition, in the upgrading process of the vehicle-mounted information entertainment system, the upgrading progress is fed back to the TBOX through the Ethernet, and the TBOX reports the upgrading progress to the OTA cloud through the third DNN channel.
