Method and system for sampling and converting vehicular network data

A system for sampling and converting vehicular network data, comprising:

• a vehicle bus, receiving an original signal;
• wherein the original signal includes a plurality of data signals;
• a vehicle host, electrically connected to the vehicle bus to receive the original signal, and selecting one of the data signals from the original signal;
• wherein the vehicle host further establishes a data table according to the selected one of the data signals, and determines whether the original signal includes any data signal remaining unselected;
• wherein when the original signal includes any data signal remaining unselected, the vehicle host selects another one of the data signals from the data signals of the original signal remaining unselected;
• wherein when all of the data signals included in the original signal are selected, the vehicle host differential samples data in the data table corresponding to other time sequences by using the data in the data table corresponding to a first time sequence as a reference to generate a differential data table, and compresses the differential data table;
• a network module, electrically connected to the vehicle host;
• wherein when the vehicle host compresses the differential data table, the vehicle host further uploads the compressed differential data table to a cloud server.
