Title:
COMMUNICATION SYSTEM AND COMMUNICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2019/155682
Kind Code:
A1
Abstract:
This vehicle is provided with a first calculation processing unit which performs control processing of a communication network mounted in a vehicle, and a second calculation processing unit which generates communication data which is transmitted to a device outside of the vehicle. The first calculation processing unit is provided with a Huffman encoding unit which encodes, with Huffman codes, encoding target data included in a frame of the communication network mounted in the vehicle, and the second calculation processing unit is provided with a Huffman code decoding unit which decodes Huffman encoded data, and a range encoding unit which encodes said decoded result with range codes, wherein the range encoded data encoded by the range encoding unit is transmitted to the device outside of the vehicle.
