According to different communication methods and functions, the vehicle communication system can be divided into the following categories:

In-vehicle wireless communication system

The vehicle-mounted wireless communication system refers to the equipment and technology that realizes communication between vehicles and between vehicles and the outside world through radio waves. According to different communication protocols and standards, the vehicle-mounted wireless communication system can be divided into different types such as Bluetooth, Wi-Fi, DSRC, etc.

In-vehicle mobile communication system

The vehicle-mounted mobile communication system refers to the equipment and technology that enables communication between vehicles and between vehicles and the outside world through mobile networks. This system can achieve communication through mobile phones or other mobile devices, including voice calls, text messages, data transmission, etc.

In-vehicle navigation and communication system

The in-vehicle navigation and communication system refers to equipment and technology that combines multiple functions such as navigation, communication, and entertainment. This system can realize functions such as vehicle positioning, navigation, voice recognition, and multimedia playback, providing drivers with a more convenient driving experience.

3. Development History of In-Vehicle Communication Systems

The development of vehicle communication systems can be divided into the following stages:

Phase 1: 1980s to early 1990s

At this stage, the vehicle communication system mainly relies on analog signal technology, including analog radio, analog signal radio, etc. The functions of these devices are relatively simple and the signal quality is unstable.

The second stage: 1990s to early 21st century

During this period, digital signal processing technology was gradually applied to in-vehicle communication systems, and digital radios, CD players and other devices appeared. At the same time, in-vehicle navigation systems also began to appear, but their functions were relatively simple and their accuracy was relatively low.

The third stage: the beginning of the 21st century to the present

During this period, with the development and popularization of mobile communication technology, vehicle-mounted mobile communication systems have been widely used. At the same time, vehicle-mounted navigation and communication systems have gradually developed into multifunctional, high-precision equipment that integrates multiple functions such as navigation, communication, and entertainment.

IV. Status and Trends of In-Vehicle Communication Systems
