What is the TBOX can protocol?

Telematics BOX, referred to as car T-BOX, car networking system consists of four parts: host, car T-BOX, mobile phone APP and background system. The host computer is mainly used for audio-visual entertainment and vehicle information display; Automobile T-BOX is mainly used to communicate with the background system/mobile APP, and realize the vehicle information display and control of the background system/mobile APP.

__-BOX communicates with the upper computer through CAN bus to realize the transmission of instructions and information, so as to obtain information including vehicle status and button status, and transmit control instructions. Through audio connection, the microphone and speaker output of both parties can be realized. Indirect communication (two-way) with the mobile APP is carried out in the form of data link through the background system. The communication between T-BOX and the background system also includes voice and short messages, which are mainly used to realize one-button navigation and remote control.

__-BOX CAN deeply read automobile CAN bus data and private protocol, and T-box terminal collects automobile bus data through OBD module and MCU and reversely controls private protocol; At the same time, T-box can locate the vehicle position through the GPS module, and use the network module to transmit the data to the cloud server through the network. Car owners can obtain information such as car condition report, driving report, fuel consumption statistics, fault reminder, illegal inquiry, location trajectory, driving behavior, security and theft prevention, reservation service, remote car search and so on. From the cloud server through the network on the mobile APP. They can also indirectly interact with the network module through the connection between the network module on the mobile APP and the server, and then finally use the single chip microcomputer to provide control of the car door, window, lights, door locks and speakers.
