Embodiment 1

[0035] see figure 1 , figure 2 , image 3 and Figure 4 As shown, the present invention provides a calibration system applied to vehicle monitoring terminals, which includes an OBD vehicle-mounted terminal and a background server; the OBD vehicle-mounted terminal performs wireless data communication with the background server. The OBD vehicle-mounted terminal is used to measure and obtain the parameter information required for the calibration of the vehicle, and transmit the required parameter information to the background server; the background server is used to call the background calibration algorithm, and perform calculation processing on the calibration parameter information to obtain The calibration result information is sent back to the OBD vehicle terminal.

[0036] The OBD vehicle terminal includes a host module, a multi-sensor module, a wireless communication module and a vehicle speed measurement interface module, and the multi-sensor module, the wireless commun...

Embodiment 2

[0043] Embodiment 2 of the present invention provides a calibration system applied to a vehicle monitoring terminal, which is substantially the same as the technical solution of Embodiment 1, the main difference being:

[0044] The OBD vehicle-mounted terminal further includes a start-up control module, which is used to control the start-up work of the host module, multi-sensor module, wireless communication module and vehicle speed measurement interface module according to external input start-up information. The start control module is connected to the host module, the start control module converts the pressing action or touch action input from the outside into control information, and outputs the control information to the host module to control the host module Start the work, and then output the control information to the multi-sensor module, wireless communication module and vehicle speed sensor module respectively through the host module, and control the start-up work of ...

Embodiment 3

[0046] see again Figure 1 to Figure 4 As shown, Embodiment 3 of the present invention provides a calibration method applied to a vehicle monitoring terminal, wherein the OBD vehicle terminal performs wireless data communication with the background server. The OBD vehicle-mounted terminal is used to measure and obtain the parameter information required for the calibration of the vehicle, and transmit the required parameter information to the background server; the background server is used to call the background calibration algorithm, and perform calculation processing on the calibration parameter information to obtain The calibration result information is sent back to the OBD vehicle terminal. The OBD vehicle terminal includes a host module, a multi-sensor module, a wireless communication module and a vehicle speed measurement interface module, and the multi-sensor module, the wireless communication module and the vehicle speed measurement interface module are all connected t...

Abstract

The invention relates to a calibrating system and method applied to a vehicle monitoring terminal. The calibrating system comprises an OBD vehicle-mounted terminal and a background server. The OBD vehicle-mounted terminal comprises a host module, a multi-sensor module, a wireless communication module and a vehicle speed measurement interface module. The wireless communication module is used for conducting wireless data communication with the background server, the multi-sensor module is used for measuring and obtaining G-sensor tri-axial acceleration speed information, tri-axial angular speed information, geomagnetic information, pressure information and temperature information of a vehicle, the vehicle speed measurement module is used for measuring and obtaining driving speed information of the vehicle and the host module is used for packaging the data and transmitting the data to the background server. The background server is used for calculating the received calibration parameter information, and calibration result information obtained after processing is transmitted to the OBD vehicle-mounted terminal. The calibrating system and method obviously improve the calibration precision and efficiency of the vehicle monitoring terminal and have the advantages of being good in user experience and the like.

Description

technical field [0001] The invention relates to a calibration system and method applied to a vehicle monitoring terminal. Background technique [0002] With the rapid development of automotive electronics, the technological maturity of the automotive industry continues to increase. As one of the main means of transportation for people's daily travel, automobiles have become an indispensable part of people's daily life, study, and work. However, with the large-scale popularization of motor vehicles, traffic congestion is becoming more and more serious, especially in the bustling roads in the city center, mixed roads with people and vehicles, and narrow roads, which are caused by bad driving habits such as sudden braking and sudden acceleration. Rear-end collisions and collision accidents are not uncommon, especially for novice drivers who lack driving experience. They do not understand the performance of the vehicle, do not grasp the strength of acceleration and deceleration,...
