[0100] Step S20: collecting acceleration signals.

[0101] It is easy to understand that the step of collecting the acceleration signal specifically includes: obtaining the first axis analog voltage value, the second axis analog voltage value and the third axis analog voltage value; and determining the acceleration signal according to the first axis analog voltage value, the second axis analog voltage value and the third axis analog voltage value.

[0102] Specifically, the intelligent vehicle computer obtains the first axis analog voltage value, the second axis analog voltage value and the third axis analog voltage value of the three-axis sensor; determines the acceleration signal according to the first axis analog voltage value, the second axis analog voltage value and the third axis analog voltage value. Determine the vehicle body posture information according to the acceleration signal, and obtain the vehicle body elevation angle information according to the vehicle body posture information; Figure 3 As shown, the vehicle body elevation angle information may be an included angle B.

[0103] Step S30: determining whether the current position is located on a preset parking base according to the current GPS position signal and the acceleration signal.

[0104] It should be noted that the step of determining whether the current position is located on a preset parking base based on the current GPS position signal and the acceleration signal specifically includes: determining the target angle information of the preset parking base based on the current GPS position signal; determining the vehicle body posture information based on the acceleration signal, and obtaining the vehicle body elevation angle information based on the vehicle body posture information; comparing the target angle information with the vehicle body elevation angle information; and determining whether the current position is located on the preset parking base based on the comparison result.

[0105] Specifically, refer to Figure 3 The preset parking base comprises a fixed base (1) covering the parking space and a column (2) arranged above the fixed base (1) for supporting the shared electric motorcycle. The column (2) comprises a support body (3) and a bearing body (4), and the support body (3) and the fixed base (1) form an angle A, and the angle A can be the target angle information of the preset parking base determined by the intelligent vehicle machine according to the current GPS position signal, and the target angle information can be the angle of the preset parking base.

[0106] It is easy to understand that the intelligent vehicle machine obtains the first axis analog voltage value, the second axis analog voltage value and the third axis analog voltage value of the three-axis sensor; determines the acceleration signal according to the first axis analog voltage value, the second axis analog voltage value and the third axis analog voltage value. Determine the vehicle body posture information according to the acceleration signal, and obtain the vehicle body elevation angle information according to the vehicle body posture information; Figure 3 As shown, the vehicle body elevation angle information may be an angle B, and the target angle information is compared with the vehicle body elevation angle information; and whether the current position is located on a preset parking base is determined based on the comparison result.

[0107] Step S40: When the current position is not located on the preset parking base, a warning signal is issued.

[0108] It is easy to understand that when the angle of the preset parking base, i.e., angle A, is the same as the angle of the body inclination, i.e., angle B, it is determined that the current position belongs to the target fixed-point parking position, and the shared electric motorcycle is accurately parked in the parking space when parking, realizing standardized parking of the shared electric motorcycle; when the angle of the preset parking base, i.e., angle A, is different from the angle of the body inclination, i.e., angle B, it is determined that the current position does not belong to the target fixed-point parking position, and the shared electric motorcycle is not accurately parked in the parking space when parking, and a warning signal is issued.

[0109] This embodiment collects the current GPS position signal; collects the acceleration signal; determines whether the current position is located on the preset parking base according to the current GPS position signal and the acceleration signal; and sends a warning signal when the current position is not located on the preset parking base. In the above manner, the shared electric motorcycle is equipped with an intelligent vehicle machine and a matching three-axis sensor. When returning the vehicle, the current GPS position signal is collected by the intelligent vehicle machine to determine whether the shared electric motorcycle is near the parking area. The body posture can be determined by gravity decomposition to the acceleration signal of the three-axis sensor. The intelligent vehicle machine determines whether the vehicle can be returned. When it is recognized that the body is parked at the correct angle above the preset parking base, it can park. Otherwise, a warning signal is sent, so that the shared electric motorcycle can be parked accurately in the parking space when parking, and the shared electric motorcycle can be parked in a standardized manner, which solves the technical problem that the existing GPS cannot ensure that the shared electric motorcycle is parked accurately in the parking space.
