Example Embodiment

[0038] Example 1

[0039] See figure 1 The GPS data-based track correction control system includes a vehicle central control system 1 and a server 3. The vehicle central control system 1 includes a data acquisition module 11 and a vehicle control module 16. The data acquisition module 11 is used to locate the vehicle through GPS The device collects current vehicle information and position latitude and longitude data; it can also collect vehicle driving time, speed, phase angle and other information;

[0040] The vehicle control module 16 is used to control the opening or closing of the vehicle; for example, the vehicle control module 16 controls the vehicle to open or close the electrical door, and the vehicle control module 16 uses the central control system 1 to open the vehicle electrical door; Module 16 closes the vehicle electric door through the central control system 1; locks the vehicle rear wheel lock command through the vehicle central control system 1; locks the vehicle ...

Example Embodiment

[0046] Example 2

[0047] See figure 1 The difference from the above-mentioned embodiment is that the server 3 further includes a data storage module 33, and the storage module 33 is used to store GPS data track information after correction.

Example Embodiment

[0048] Example 3

[0049] See figure 2 The difference from the above-mentioned embodiment lies in a method for tracking deviation correction based on GPS data. The method includes the following steps:

[0050] Step 1), start S1;

[0051] Step 2) Obtain the position and positioning information of the positioning point S2;

[0052] Step 3) Perform data correction analysis and judgment on the GPS location information track S3;

[0053] Step 4), determine whether the change points of the GPS position fixed-point trajectory data are less than 10%, if yes, go to the next step S4;

[0054] Step 5) According to the analysis and judgment of the correction data analysis module, the final trajectory S5 of GPS data is obtained;

[0055] Step 6), end S6.

[0056] The above-mentioned step 3) determines whether the number of changes in the GPS position fixed-point trajectory data is less than 10%, if not, then returns to step 2) S2.

[0057] See image 3 , Figure 4 , Figure 5 In this embodiment, the af...

Abstract

The invention discloses a rectify deviation control system and method based on a GPS data track. The system comprises a vehicle central control system and a server. The vehicle central control systemcomprises a data acquisition module and a vehicle control module. The server comprises a data receiving module and a rectify deviation data analyzing module. The vehicle central control system transmits the collected vehicle information and vehicle control information to the server through the Internet of Things, and the server analyzes and processes the received information to control the vehicleoperation. The method comprises the following steps of: 1. obtaining positioning information of a positioning point; 2. performing analysis and judgment on the data rectify deviation of the GPS position information track; 3. judging whether the change number of the pointing track data of the GPS position is less than 10%; and 4. obtaining the final track of the GPS data according to the analysisof the rectify deviation data analyzing module. The invention provides the rectify deviation control system and method based on the GPS data track, which is small in positioning error range, accuratein positioning, low in positioning cost and high in efficiency.
