Abstract

The invention discloses a vehicle and a communication system and method thereof. The communication system of the vehicle comprises a first CAN network, a second CAN network, an Ethernet and a gateway.The first CAN network, the second CAN network and the Ethernet are all connected with the gateway; the first CAN network, the second CAN network and the Ethernet are respectively used for transmitting data of a target domain according to network requirements of the first CAN network, the second CAN network and the Ethernet; the gateway is used for receiving the data transmitted in the source network and converting the data in the source network so as to meet the transmission requirement of the target network; and the source network and the target network are any one of the first CAN network,the second CAN network and the Ethernet, and the source network and the target network are different networks at the same moment. According to the system, normal interaction of data among all networksin the whole vehicle is achieved, and the phenomena of data frame loss or wrong frames and data interaction incapability are effectively avoided.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a vehicle and its communication system and method. Background technique [0002] The vehicle network mainly consists of power network, comfort network, ECM network, ESC network, start network and other networks. In related technologies, a gateway in the vehicle connects various networks in the vehicle together, and forwards data between different networks through the gateway, so as to realize data interaction between different networks. However, in the process of data exchange between different networks, data frame loss or error frames often occur, and data cannot be exchanged. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. [0004] Therefore, the first object of the present invention is to provide a communication system for a vehicle, which can realize normal data inter...
