Smart antenna system and communication method

Abstract

Embodiments of the present invention provide a smart antenna system and a communication method. The smart antenna system includes an antenna communication unit and an interaction unit, wherein the antenna communication unit includes an array antenna module and a first communication controller, and the interaction unit It includes a central control module and a second communication controller. The antenna processing module in the array antenna module processes the signal received by the antenna group and transmits it to the first processor, and then transmits it to the central control module through the first communication controller and the second communication controller, so as to realize interactive function. The intelligent antenna system reduces the use of vehicle body wire harnesses and high-frequency connectors, realizes the lightweight of the vehicle body, and reduces the cost. On the other hand, the streamlined system further reduces the cost and is easy to promote.

Description

technical field [0001] The invention relates to the field of vehicle antennas, in particular to an intelligent antenna system and a communication method. Background technique [0002] With the rapid development of the automobile industry, the application of communication infrastructure in the automobile industry has become more and more extensive, and people's dependence on automobiles has become higher and higher, so the demand for smart antennas has surged. Most current cars install shark fin antennas on the top of the car body, including AM / FM antennas, GNSS antennas, 4G antennas, etc. The antennas are usually connected to the main driving computer system by means of coaxial cables. [0003] The existing vehicle antennas have the following problems: more wiring harnesses and high-speed connectors are used, resulting in a sharp increase in cost; the layout of the antenna in the vehicle is affected by the metal sheet, the installation position is limited, and the antenna si...

AI Technical Summary

Problems solved by technology

[0003] The existing vehicle antennas have the following problems: more wiring harnesses and high-speed connectors are used, resulting in a sharp increase in cost; the layout of the antenna in the vehicle is affected by the metal sheet, the installation position is limited, and the antenna signal attenuation is large; the increase in the body wiring harness and connectors leads to The layout of the whole vehicle is relatively complicated, and the cost of error checking and maintenance increases; the goal of lightweight body is difficult to achieve

On the other hand, the existing in-vehicle network connection system is relatively redundant, including the driving computer system, the Internet of Vehicles system, antennas, controllers, etc., resulting in high costs and complicated system connections, which is not conducive to promotion
