1. A vehicle hybrid communication system, comprising:
a vehicle communication device, mounted in a vehicle, and comprising a vehicle controller and multiple vehicle communication interfaces; wherein the vehicle communication interfaces are electrically connected to the vehicle controller; and
a field communication device, mounted on a roadside, and comprising a field controller and multiple field communication interfaces; wherein the field communication interfaces are electrically connected to the field controller; wherein multiple communication channels are established between at least two of the field communication interfaces and at least two of the vehicle communication interfaces, allowing a network packet to be transferred between the vehicle communication device and the field communication device via the communication channels;
wherein the vehicle controller respectively defines a bandwidth level and a speed level based on a real-time bandwidth and a real-time connection speed of each of the communication channels; wherein the vehicle controller then creates a score based on the bandwidth level and the speed level of each of the communication channels, and then the vehicle controller sets one of the communication channels with the best score as a main communication channel; wherein via the main communication channel, the vehicle controller transfers data to the field communication device.
