[0068] The present invention will be further described below in conjunction with the accompanying drawings.
[0069] like figure 1 As shown, it is a system architecture diagram of the present invention. The present invention involves an OTA client, an OTA master and two OTA sub-control nodes that implement different functions. The OTA client communicates with the OTA sub-node where the main chip with the operating system is installed through a deployment protocol. The OTA sub-control where the main chip with the operating system is installed can directly realize the software iteration of the main chip through the operating system, and carry related applications on the operating system. It can also be updated, but the controller without an operating system needs the cooperation of the UDS parallel flashing host computer to realize the software update through the OTA sub-control node.
[0070] The OTA client is also connected to the OTA master node through a deployment protocol...
