Further, fig. 3 is a schematic flowchart of a second embodiment of the electric vehicle parking method according to the present invention, and as shown in fig. 3, the second embodiment of the electric vehicle parking method according to the present invention is proposed based on the first embodiment, in this embodiment, the step S20 specifically includes the following steps:
and step S21, acquiring the direction of the gyroscope of the target electric vehicle when the target electric vehicle is located in the preset parking area.
It should be noted that, due to the characteristic of GPS positioning, the direction of the GPS is easy to determine when the target electric vehicle is traveling at a high speed, but the direction of the GPS is difficult to determine when the target electric vehicle is traveling at a low speed or turning, and at this time, the direction of the target electric vehicle may be accurately determined by acquiring direction data of a gyroscope of the target electric vehicle, and the gyroscope data may be acquired by a gyroscope outside the target electric vehicle, or may be acquired by a gyroscope provided in the target electric vehicle, which is not limited in this embodiment.

and calibrating the initial direction according to the GPS direction, and taking the calibrated direction as the direction of the gyroscope of the target electric vehicle.

And step S22, determining the current parking direction of the target electric vehicle according to the gyroscope direction.
It should be understood that by analyzing the data of the gyroscope, the gyroscope direction of the target electric vehicle can be obtained, and calibrating the initial direction of the gyroscope by using the GPS direction can enable the target electric vehicle to use the calibrated initial direction as a more accurate current parking direction when parking.

It can be understood that the corresponding comparison result can be obtained by comparing the current parking direction with the preset parking direction, and the comparison result is used as a basis for judging whether the target electric vehicle can be normally returned or not.
Further, the step S23 specifically includes the following steps:
obtaining a direction included angle between the current parking direction and a preset parking direction, and comparing the direction included angle with a preset deviation angle;
when the direction included angle is larger than or equal to the preset deviation angle, judging that the comparison result is that the current parking direction is inconsistent with the preset parking direction;
and when the direction included angle is smaller than the preset deviation angle, judging that the comparison result is that the current parking direction is consistent with the preset parking direction.
It should be understood that, by comparing the direction included angle between the current parking direction and the preset parking direction with the preset deviation angle, it can be determined whether the current parking direction is consistent with the preset parking direction.

and step S11, acquiring the GPS signal intensity of the current running environment of the target electric vehicle.
It should be noted that the GPS signal strength is obtained by a GPS signal transceiver mounted on the target electric vehicle, and it can be determined to some extent whether GPS positioning is accurate through the GPS signal strength.
Further, the step S11 is followed by the following steps:
when the current vehicle speed is less than the preset vehicle speed or the GPS signal intensity is less than or equal to the preset signal intensity, starting a Bluetooth switch of the target electric vehicle;

when the parking electric vehicle exists in the target range, acquiring the vehicle distance between the parking electric vehicle and the target electric vehicle;
and judging whether the target electric vehicle is positioned in a preset parking area corresponding to the parking electric vehicle or not according to the vehicle distance.
It should be understood that when the current speed of the target electric vehicle is less than a preset speed or when the GPS signal strength is less than or equal to the preset signal strength, it indicates that the positioning information of the target electric vehicle is obtained only by the GPS and is not accurate enough, and at this time, a vehicle that has been parked nearby, that is, the parked electric vehicle, may be searched by turning on a bluetooth switch of the target electric vehicle, where the parked electric vehicle is an electric vehicle that has been parked in a preset parking area; and then calculating the vehicle distance between the parking electric vehicle and the target electric vehicle, and determining whether the target electric vehicle is located in a preset parking area corresponding to the parking electric vehicle according to the vehicle distance, so that the specific position of the target electric vehicle is determined more accurately, the accuracy of standard parking is improved, the correct returning process is ensured to be started, and the normal returning operation of the electric vehicle is ensured in a place with poor GPS signals.
Further, the step of judging whether the target electric vehicle is located in a preset parking area corresponding to the parking electric vehicle according to the vehicle distance specifically comprises the following steps:
acquiring the current parking position of the parking electric vehicle;
determining the relative distance between the parking electric vehicle and the edge of a preset parking area in a target direction according to the current parking position, wherein the target direction is the direction of the target electric vehicle relative to the current parking position;
when the distance is smaller than the relative distance, determining that the target electric vehicle is located in the preset parking area;
and when the distance is greater than or equal to the relative distance, determining that the target electric vehicle is not located in the preset parking area.
It can be understood that the distance between the parking electric vehicle and the edge of the preset parking area is calculated, and compared with the relative distance of the target electric vehicle, whether the target electric vehicle is in the preset parking area can be determined, so that the accuracy of position judgment of the target electric vehicle is improved, and the target electric vehicle is used as a judgment basis for subsequent returning operation.
And step S12, when the GPS signal intensity is greater than the preset signal intensity, acquiring the GPS positioning information of the target electric vehicle.
It can be understood that when the GPS signal strength is greater than the preset signal strength, it indicates that the positioning information corresponding to the GPS signal is relatively accurate, and the GPS positioning information of the target electric vehicle can be determined through the acquired GPS data.
And step S13, acquiring the position coverage of the preset parking area.
It will be appreciated that the element parking area will correspond to a range of corresponding size, i.e. location coverage.
And step S14, determining the current position of the target electric vehicle according to the GPS positioning information, and matching the current position with the position coverage range.
It should be understood that the current position of the target electric vehicle can be determined through the GPS positioning information, and whether the target electric vehicle is located in the preset parking area is determined by matching the current position with the position coverage, that is, by checking whether the current position is within the position coverage.
And step S15, when the current position is matched with the position coverage range, determining that the target electric vehicle is located in the preset parking area.
And step S16, when the current position is not matched with the position coverage range, judging that the target electric vehicle is not in the preset parking area.
It can be understood that when the current position matches the position coverage, that is, the target electric vehicle has entered a preset parking area, it is determined that the target electric vehicle is located in the preset parking area, and when the current position does not match the position coverage, that is, the target electric vehicle has not entered the preset parking area, it is determined that the target electric vehicle is not located in the preset parking area.
According to the scheme, the GPS signal intensity of the current running environment of the target electric vehicle is acquired; when the GPS signal intensity is greater than the preset signal intensity, acquiring the GPS positioning information of the target electric vehicle; acquiring a position coverage range of a preset parking area; determining the current position of the target electric vehicle according to the GPS positioning information, and matching the current position with the position coverage range; when the current position is matched with the position coverage range, the target electric vehicle is judged to be positioned in the preset parking area; when the current position is not matched with the position coverage range, judging that the target electric vehicle is not in the preset parking area; the specific position of the target electric vehicle can be accurately determined, the accuracy rate of standard parking is improved, the correct returning process is guaranteed to be started, the returning operation of the electric vehicle is guaranteed to be normally carried out in a place with poor GPS signals, the pressure of electric vehicle management is reduced, the risk of traffic jam is reduced, and the phenomenon that the electric vehicle is randomly stopped and placed is improved.
