It should be understood that the terminal device may send the vehicle-seeking request to the surrounding vehicle devices in various ways, for example, the terminal device may send the vehicle-seeking request through a 3G, 4G, etc. network, or the terminal device may send the vehicle-seeking request through a surrounding wireless network, or the terminal device may send the vehicle-seeking request through a dedicated Short Range communications (dsrc) network.
It should be noted that, in this embodiment, the terminal device, the vehicle device, and the roadside information station are described as an example in which all communicate via the DSRC network, that is, all of the terminal device, the vehicle device, and the roadside information station in this embodiment have a DSRC communication module.
Among them, DSRC is an efficient wireless communication technology. The system can realize information interaction between vehicles, information interaction between vehicles and roadside information sites, and information interaction between terminal equipment such as mobile terminals and vehicles.
Specifically, when the owner needs to search for the vehicle, the terminal device broadcasts the vehicle searching request in a preset geographic range of the terminal device through the DSRC communication module. Correspondingly, vehicle devices located within the preset geographic range receive the vehicle searching request through the DSRC communication module.
And 102, inquiring a pre-stored first parking information database according to the vehicle information, and acquiring second key information corresponding to the vehicle information from the first parking information database if the first parking information database contains the vehicle information.
And 103, judging whether the first key information is matched with the second key information, and if the matching is successful, acquiring the vehicle position information corresponding to the vehicle information from the first parking information database.
And 104, sending the vehicle position information to the terminal equipment so that the user can determine the position of the vehicle to be searched according to the vehicle position information.
According to the vehicle searching method, a vehicle owner sends a vehicle searching request to surrounding vehicle equipment through terminal equipment, correspondingly, when the vehicle equipment determines that vehicle information in the vehicle searching request exists in a first parking information database in the vehicle equipment, the vehicle equipment obtains second key information corresponding to the vehicle information from the first parking information database, the first key information in the vehicle searching request is matched through the second key information, and if the first key information and the second key information are matched, the vehicle equipment obtains vehicle position information corresponding to the vehicle information from the first parking information database and sends the vehicle position information to the terminal equipment. Therefore, the user can obtain the position of the vehicle to be searched from the surrounding vehicle equipment through the terminal equipment, the user can conveniently search the vehicle, the vehicle searching process is simplified, and the vehicle searching convenience of the user is greatly improved.
Based on the above embodiment, in practical application, after the user obtains the vehicle position information of the vehicle to be searched, sometimes the user is not familiar with the surrounding environment, or the environment of the parking lot is complex, and the user is difficult to find the vehicle position.
The navigation method includes the steps that in order to improve experience of a user, in the process that the terminal device guides the user to find a vehicle to be searched through a navigation path, the terminal device can broadcast the navigation path through voice to navigate the user.
Based on the foregoing embodiments, in practical applications, sometimes the terminal device has a limited range for sending the seeking request, the vehicle information of the vehicle sought by the user may not exist in the parking information database in the vehicle device receiving the seeking request, and in order to enable the user to obtain the vehicle position information of the vehicle sought by the user, as an exemplary implementation manner, on the basis shown in fig. 1, as shown in fig. 2, the method may further include:
and 105, if the first parking information database does not contain the vehicle information, acquiring the target vehicle equipment with the second parking information database.
Wherein the second parking information database is different from the first parking information database in vehicle information.
As an exemplary embodiment, the vehicle device may acquire the target vehicle device having the second parking information database through the server.
As another exemplary embodiment, the vehicle device may acquire the target vehicle device having the second parking information database by information interaction with other vehicle devices.
And 106, sending the vehicle searching request to the target vehicle equipment so that the target vehicle equipment can inquire the position of the vehicle to be searched according to the second parking information database.
As an exemplary implementation, the vehicle device is provided with a DSRC communication module, and the vehicle device can send the vehicle searching request to the target vehicle device within the preset geographic range through the DSRC communication module. Correspondingly, a target vehicle device within a preset geographic range may receive a vehicle-finding request transmitted by the vehicle device through the DSRC communication module.
It should be noted that the process of querying the position of the vehicle to be searched by the target vehicle device according to the vehicle searching request is the same as the vehicle searching process of the vehicle device in the embodiment of the present disclosure, and details are not repeated here.
It should be understood that the vehicle information of the vehicle to be searched does not exist in the parking information database in the target vehicle device, and the target vehicle device forwards the vehicle searching request to the corresponding other vehicle device again to continue searching through the other vehicle device.
It should be noted that, in order to enable the user to obtain the vehicle position information of the vehicle to be searched, if it is known that the first key information is not matched with the second key information, the vehicle searching request is forwarded to the other vehicle device, so that the vehicle to be searched is continuously searched through the other vehicle device.
As an exemplary embodiment, in order to enable the user to obtain the vehicle position information of the vehicle to be searched, if it is known that the first parking information database does not contain the vehicle information, the vehicle searching request is forwarded to the other vehicle device, so as to continue searching for the vehicle to be searched through the other vehicle device.
As an exemplary embodiment, before the vehicle device forwards the vehicle seeking request, the vehicle device may acquire a sending time when the terminal device sends the vehicle seeking request and a receiving time when the vehicle seeking request is received, then calculate a time difference between the receiving time and the sending time, and determine whether the time difference exceeds a preset time threshold. And if the acquired time difference is smaller than or equal to the preset time threshold value, the vehicle equipment executes the step of forwarding the vehicle searching request to other vehicle equipment.
It should be noted that, if the learned time difference is judged to exceed the preset time threshold, the vehicle device stops forwarding the vehicle searching request.
As another exemplary embodiment, before the vehicle device forwards the vehicle searching request, the distance between the terminal device and the vehicle device is determined; judging whether the distance exceeds a preset distance threshold value; and if the acquired distance is judged to be smaller than or equal to the preset distance threshold value, the vehicle equipment executes the step of forwarding the vehicle searching request to other vehicle equipment.
And if the learned distance is judged to exceed the preset distance threshold value, the vehicle equipment stops forwarding the vehicle searching request.
It should be noted that the distance between the vehicle device and the terminal device may be obtained in various ways, for example, as follows:
as an example, when the vehicle-finding request includes the position information of the terminal device, the vehicle device may acquire the current position information of the vehicle device through a GPS positioning device in the vehicle device, and determine the distance between the terminal device and the vehicle device according to the position information of the terminal device and the current position information of the vehicle device.
As another example, the vehicle device may acquire the location information of the terminal device and the location information of the vehicle device through the server, and determine the distance between the terminal device and the vehicle device according to the location information of the terminal device and the location information of the vehicle device.
As another example, the vehicle device may send an acquisition request to the server to acquire the distance between the vehicle device and the terminal device, where the acquisition request may include a vehicle identification of the vehicle device and a terminal identification of the terminal device.
Correspondingly, the server respectively acquires the position information of the vehicle equipment and the position information of the terminal equipment according to the vehicle identification and the terminal identification, determines the distance between the terminal equipment and the vehicle equipment according to the position information of the vehicle equipment and the position information of the terminal equipment, and returns the distance between the terminal equipment and the vehicle equipment to the vehicle equipment.
In order to enable vehicles in a preset area to continue to search for vehicles to be searched, as an exemplary implementation manner, after vehicle equipment stops forwarding the vehicle searching request, when it is monitored that the vehicle equipment performs information interaction with a road side information site encountered for the first time, the vehicle equipment sends the vehicle searching request to a central server through the road side information site, and the vehicle searching request is used for instructing the central server to forward the vehicle searching request to the road side information site in the preset area.
The preset area is an area formed by taking the position of the terminal equipment as the center and taking the preset distance as the radius.
Correspondingly, in order to reduce the occupation of the information on the storage resource of the central server, as an exemplary embodiment, after the central server successfully forwards the vehicle searching request to the roadside information site in the preset area, the central server may delete the vehicle searching request.
After the roadside information station in the preset area receives the vehicle searching request, the roadside information station in the preset area can forward the vehicle searching request to the corresponding vehicle equipment, so that other vehicle equipment in the preset area can continue to search the vehicle.
As an exemplary embodiment, the roadside information station may forward the vehicle searching request to vehicle devices within a preset geographic range through a DSCR technology. Correspondingly, the vehicle equipment in the preset geographic range receives the vehicle searching request sent by the roadside information station through the DSCR communication module, and continues to search for the vehicle to be searched based on the vehicle searching request until the vehicle to be searched is found.
Based on any of the above embodiments, before the vehicle device receives the vehicle searching request sent by the terminal device, as shown in fig. 3, the vehicle searching method may further include:
The parking information may include, but is not limited to, vehicle information of the vehicle to be sought, second key information, vehicle position information, and the like, and the parking information may also include other information, for example, the parking information may also include parking time of the vehicle to be sought, and the like.
The wireless network may include, but is not limited to, a dedicated short-range communications DSRC network, among others. For example, the wireless network may also be a WIFI network, a 3G network, or a 4G network.
In one embodiment of the invention, in order to facilitate the subsequent user to search for the vehicle through the vehicle devices around the subsequent user, after the vehicle device acquires the parking information, the vehicle device may forward the parking information to the other vehicle devices, so that the other vehicle devices store the parking information. Therefore, parking information is stored in a plurality of vehicle devices, and a user can conveniently and quickly acquire the position of a searched vehicle through the surrounding vehicle devices.
It should be noted that, in order to avoid occupation of the storage resource of the vehicle device by the parking information of the vehicle to be searched after the vehicle device travels to a distance from the vehicle to be searched, as an exemplary embodiment, the parking information in the first parking information database is deleted when the distance between the current position where the vehicle device travels and the position of the vehicle to be searched exceeds a preset distance threshold.
As another exemplary implementation manner, after the distance between the current driving position of the vehicle device and the position of the vehicle to be searched exceeds a preset distance threshold, when it is monitored that the vehicle device performs information interaction with a roadside information site which is encountered for the first time, the parking information is forwarded to the central server through the roadside information site, and the parking information in the first parking information database is deleted. Therefore, the vehicle equipment can store the parking information of the vehicle to be searched to the central server through the roadside information station and delete the parking information in the vehicle equipment.
It should be noted that, after the central server acquires the parking information of the vehicle to be searched, the central server may forward the parking information of the vehicle to be searched to a roadside information site in a preset area. Correspondingly, the roadside information station in the preset area can forward the parking information of the vehicle to be searched to the corresponding other vehicle equipment, so that the other vehicle equipment stores the parking information of the vehicle to be searched.
The preset area is an area formed by taking a vehicle to be searched as a center and taking a preset distance as a radius.
In the practical application process, the vehicle owner can also access the central server through the terminal device with the internet function, and the vehicle searching request is sent to the central server, so that the vehicle position information of the vehicle to be searched is acquired through the central server.
After the user successfully seeks the vehicle, in order to reduce the occupation of the storage space of the vehicle device by saving the parking information, as an exemplary implementation manner, based on the embodiment shown in fig. 2, as shown in fig. 4, the vehicle seeking method may further include:
It should be noted that the deletion notification for deleting the parking information may be sent successfully by the terminal device in searching for the vehicle, or may be sent by the vehicle to be searched, which is not limited in this embodiment.
And 402, deleting the parking information in the first parking information database when the first parking information database is determined to contain the vehicle information and the second key information is determined to be matched with the first key information.
Based on the above embodiment, in order to reduce the occupation of the storage space of the target vehicle device by the parking information, the vehicle device may further forward a deletion notification to the target vehicle device, so that the target vehicle device deletes the parking information of the vehicle to be searched in the second parking information database according to the deletion notification.
As an exemplary embodiment, the vehicular device may broadcast a deletion notification over the DSRC network. The target vehicle device corresponding to the preset geographic range can receive the deletion notification through the DSRC communication module in the device, and when the vehicle information and the key information in the deletion notification are verified to be verified, the parking information of the vehicle to be searched, which is stored in the parking information database of the device, is deleted.
It should be understood that after the parking information of the vehicle to be searched is forwarded between the vehicle devices for a period of time, the parking information of the vehicle to be searched is stored in many vehicle devices. However, for the vehicle equipment far away from the vehicle to be searched, there is no great benefit for the subsequent user to search the vehicle through the terminal equipment, and the occupation of the storage resource of the vehicle equipment for saving the parking information of the vehicle to be searched is reduced. As an exemplary embodiment, before the vehicle apparatus forwards the parking information of the vehicle to be searched to other vehicle apparatuses, the vehicle apparatus may further acquire a transmission time when the vehicle to be searched transmits the parking information and a reception time when the parking information is received, then calculate a time difference between the reception time and the transmission time, and determine whether the time difference exceeds a preset time threshold. And if the acquired time difference is smaller than or equal to the preset time threshold value, the vehicle equipment forwards the parking information of the vehicle to be searched to other vehicle equipment.
The preset time threshold is a preset time threshold for information transmission between vehicles, and may be half an hour or one hour, for example.
It should be understood that, in practical application, the preset time threshold may be set according to a requirement, and the preset time threshold is not limited in this embodiment.
If the time difference is judged to be larger than the preset time threshold, the vehicle equipment stops forwarding the parking information of the vehicle to be searched.
Based on the implementation, as an exemplary implementation manner, before the vehicle device forwards the parking information of the vehicle to be searched to other vehicle devices, the vehicle device may further determine a distance between the vehicle to be searched and the vehicle device, and determine whether the distance exceeds a preset distance threshold. And if the distance is judged to be smaller than or equal to the preset distance threshold value, the vehicle equipment stops forwarding the parking information of the vehicle to be searched.
It should be noted that, according to different application scenarios, the vehicle device may determine the distance between the vehicle to be searched and the vehicle device in multiple ways, for example, as follows:
as an example, when the parking information includes the position information of the vehicle to be sought, the vehicle device may acquire its current position information through a GPS positioning device in itself, and determine a distance between the vehicle to be sought and the vehicle device according to the position information of the vehicle to be sought and the current position information of the vehicle device.
