Problems solved by technology

In order to meet the requirements of so many functions, the smart host in the prior art uses a high-performance processor and GPU integrated into one body. However, due to the communication involving many sensors, and the data types of different sensors and bus sensors may be different, making it exist The analysis and communication of many different types of data make its communication inefficient
In addition, the analysis of data types in the prior art is often performed at the user layer, and the analysis at the user layer will generate more redundant data

Abstract

The invention provides an MCU communication service method of an intelligent host, which is applied to the intelligent host comprising an MCU and an SoC, and at least comprises the following steps: monitoring data received by a virtual channel in an external hardware link, and analyzing the data; before data communication starts, initializing assignment, and designing different initialization conditions, for example, mapping a plurality of virtual channels to a single physical communication link, classifying transmitted data, and transmitting or receiving communication data of the same category through the same virtual channel. User data can be analyzed at a bottom layer, and generation of redundant data is avoided. In addition, the sending data de-duplication updating is added, so that useless operation of data sending processing is avoided.

Description

technical field [0001] The invention relates to a communication method for an intelligent host for vehicles, in particular to an MCU communication service method for an intelligent host. Background technique [0002] With the continuous advancement of science and technology, cars are developing toward intelligence, automation, and unmanned. At this stage, the smart host integrates the central control entertainment system, instrument alarm system and Ethernet 360 panoramic surround view system. The main functions of the smart host Specifically, it includes functions such as body information display, air conditioning control, radio, audio and video playback, Bluetooth, WiFi, radar alarm, driving assistance, and 360 surround view. So many body signals have brought unprecedented challenges to the hardware structure and communication of the intelligent host. In order to meet the requirements of so many functions, the smart host in the prior art uses a high-performance processor ...
