Embodiment 1

[0041] refer to figure 1 , this embodiment includes the following steps:

[0042] S10: Initialize the device;

[0043] S20: Detect the connection status of the OBD interface;

[0044] S30: Detect input information;

[0045] S41: read input information;

[0046] S42: Extract corresponding calibration data;

[0047] S431: Converting the stored information into different communication formats;

[0048] S432: Perform digital-to-analog conversion on the information after the communication format conversion.

[0049] S44: If an error occurs, go to step S60; otherwise, go to the next step

[0050] S50: Send the calibration data to the TBOX through the OBD interface for calibration; if successful, go to step S30; otherwise, go to step S60.

[0051] S60: Set the maximum number of retries for errors, and retry the steps that fail to process. When the number of retries is less than the maximum number of retries, the re-jump of the failed step pair is successful, and then jump to t...

Embodiment 2

[0059] The equipment of this embodiment specifically includes such as figure 2 In the device shown, the external input device is connected to the data processor, the data processor is connected to the LED indicator light, the data memory is connected to the data memory, and the data processor is connected to the connection port.

[0060] The external input device is a physical button input device, the data memory is a readable and writable data memory, and the connection port is an OBD interface.

[0061] When working, the physical button input device is operated by the user, and the signal is sent to the data processor, and the data processor retrieves relevant data from the data storage device to the data processor according to the relevant information. After the processing is completed, the relevant information will be sent out through the OBD interface, and the information on whether the calibration is successful or not can be obtained through the OBD interface. During t...

Abstract

The invention discloses a TBOX parameter calibration method and device based on a CAN network; the method comprises the following steps: S10, initializing equipment; S20, detecting OBD interface connecting conditions; S30, detecting input information; S40, reading calibrated data corresponding to the input information; S50, sending the calibrated data to the TBOX through the OBD interface for calibration. An existing method uses upper and lower computers to cooperate so as to calibrate the TBOX; the TBOX parameter calibration method uses an integrated machine to replace said computers for calibration, and fully utilizes the vehicle OBD interface function to write the TBOX calibrated data, thus greatly reducing the calibration device volume, greatly reducing equipment cost, providing calibration conveniences for vehicle manufacturers and authorized maintenance mechanisms, and improving the calibration efficiency.

Description

technical field [0001] The invention relates to the field of automobile communication, in particular to a CAN network-based TBOX parameter calibration method and a device thereof. Background technique [0002] With the technical development of the Internet of Vehicles, the communication function of the car has been continuously strengthened. Various high-level information collection devices have been installed on the car to form the Internet of Vehicles. Monitoring of driving status and providing various convenient functions for drivers. [0003] In the Internet of Vehicles system, TBOX is an important component, and its role is mainly in communication and positioning functions, as a bridge connecting vehicles and background servers. In order to realize background communication, voice call and other functions, in T-BOX, it is generally necessary to write the background server address through the diagnosis protocol, and to meet the calibration parameters such as various call...
