DETAILED DESCRIPTION
[0022] The above and other technical contents, features and effects of the present invention will be clearly presented in the following detailed description of the preferred embodiments with reference to the drawings. Through the description of the specific implementation methods, the technical means and effects adopted by the present invention to achieve the predetermined purpose can be more deeply and specifically understood. However, the drawings are only for reference and explanation purposes and are not used to limit the present invention.
[0023] Embodiment 1
[0024] The present invention provides a vehicle location sharing method, please refer to the attached Figure 1 The vehicle location sharing method provided in this embodiment includes the following steps:
[0025] Step S1, determining the real-time position of the sharing initiating vehicle through the vehicle positioning system of the sharing initiating vehicle;
[0026] Step S2, generating a location sharing map including the real-time location of the sharing initiating vehicle according to the real-time location of the sharing initiating vehicle, wherein the location sharing map is an augmented reality map corresponding to a map sharing area within a certain range in reality;
[0027] Step S3: displaying the location sharing map on the vehicle-mounted displays of other vehicles located in the map sharing area.
[0028] Specifically, in one implementation, the vehicle-mounted positioning system described in step S1 may include at least one of a GPS locator, a Beidou locator, a base station locator, a WIFI locator, a Bluetooth locator, and the like.
[0029] It can be understood that the vehicle location sharing method provided in the embodiment of the present invention should also include a cloud server for processing and storing information. The cloud server can adopt at least one of cloud computing technology, big data technology, artificial intelligence technology or blockchain technology, etc.
[0030] In one embodiment, in step S2, a location sharing map including the real-time location of the sharing initiating vehicle is generated based on the real-time location of the sharing initiating vehicle. The location sharing map is an augmented reality map corresponding to a map sharing area within a certain range in reality and is based on the cloud server. The cloud server is used to generate a location sharing map including the real-time location of the sharing initiating vehicle based on the location information of the sharing initiating vehicle, and the location sharing map is sent to the on-board display of the vehicle located within the location sharing map for display.
[0031] Optionally, the method of joining the location sharing map can be: (1) pre-authorizing the target vehicle through the initiating sharing vehicle, and when the pre-authorized vehicle enters the map sharing area, it automatically joins the shared map; (2) the sharing initiating vehicle sends a joining invitation to the target vehicle, and the vehicle that accepts the invitation automatically joins the location sharing map; (3) other vehicles that have not obtained pre-authorization and have not received an invitation signal can apply to join the location sharing map by searching for the location sharing signal sent by the sharing initiating vehicle.
[0032] In one embodiment, step S3 further includes: the cloud server sets access rights for other vehicles for the location sharing map through the onboard computer of the sharing initiating vehicle, and when other vehicles with location sharing map access rights enter the map sharing area, they automatically access the location sharing map. The vehicle accessing the location sharing map becomes a user of the location sharing map, and displays the location sharing map on the onboard display.
[0033] Furthermore, the on-board computer of the sharing initiating vehicle is used to grant the selected pre-authorized vehicle access to the location sharing map. When the pre-authorized vehicle is located in the map sharing area, the location sharing map is received by the on-board computer of the pre-authorized vehicle and displayed on the on-board display of the pre-authorized vehicle.
[0034] Optionally, if the pre-authorized vehicle does not receive the location sharing map within a preset waiting time after entering the map sharing area, the on-board computer of the pre-authorized vehicle sends an application to the sharing initiating vehicle to join the location sharing map; if the application is approved, the location sharing map is received by the on-board computer of the pre-authorized vehicle and displayed on the on-board display of the pre-authorized vehicle.
[0035] Furthermore, for other vehicles that have not obtained pre-authorization for the location sharing map and have not received a sharing invitation signal but have a need to join the location sharing map, the location sharing signal sent by the sharing initiating vehicle is searched through the on-board computer of the other vehicle; if the location sharing signal is found, an application to join the location sharing map is initiated through the location sharing signal; if the application is approved, the location sharing map is received through the on-board computer of the other vehicle, and the location sharing map is displayed on the on-board display of the other vehicle.
[0036] Optionally, the scope of the map sharing area is pre-set by the sharing initiating vehicle, and when the target vehicle enters the scope of the map sharing area, the on-board computer of the target vehicle issues a prompt for entering the map sharing area.
[0037] It can be understood that a sharing application sent by a vehicle that has not received a sharing invitation for more than a certain period of time in the map sharing area can be received by all vehicles located in the location sharing map, and any vehicle located in the location sharing map is granted the authority to agree to the joining application.
[0038] Furthermore, after a vehicle joins the location sharing map, the location sharing map including icons of all vehicles in the location sharing map is automatically and dynamically displayed in real time on the vehicle's onboard display from the vehicle's perspective.
[0039] Optionally, the vehicle icon may include vehicle body color, license plate number, vehicle logo, and other vehicle symbols that identify the vehicle.
[0040] Furthermore, when vehicles located in the location sharing map need to interact with each other, the vehicle icon of the vehicle to be interacted with is clicked to enter the information interaction interface, and an information interaction window pops up automatically.
[0041] In addition to information exchange, by clicking on the vehicle icon, you can also obtain information such as the driving distance between your vehicle and the clicked vehicle, and the driving time required to meet the clicked vehicle.
[0042] After a vehicle joins the location sharing map, it shares its own location information in the location sharing system through the vehicle-mounted electronic communication system, obtains the relative location information of other vehicles in the location map, and displays it on the vehicle-mounted display.
[0043] Optionally, during the process of vehicle location sharing, in order to have a clear understanding of the specific information around the shared target, the actual scene information around the vehicle can be photographed or recorded through a camera device, and the content captured by the camera device can be displayed in real time on the vehicle's on-board display within the location sharing map.
[0044] It can be understood that the camera device can be at least one of a camera, a driving recorder, a wearable device camera or a drone camera.
[0045] The following is an explanation of the vehicle location sharing method provided by the embodiment of the present invention through a multi-person self-driving scenario. Figure 2 , where the portion corresponding to 101 represents the map sharing area, and 102 represents the cloud server.
[0046] In this application scenario, multiple car owners drive to the same destination. Assuming that the initiating shared vehicle is vehicle A, vehicle A initiates location sharing through the cloud server 102 and sets the scope of the map sharing area, that is, Figure 2The range corresponding to type 101, when other target vehicles enter the range, the on-board computer receives a prompt to enter the map sharing area. Vehicle A can grant pre-authorization to target vehicles B, C, D... in advance. When target vehicles B, C, D... and the initiating sharing vehicle A are simultaneously within the range of the map sharing area, target vehicles B, C, D... automatically join the location sharing map initiated by A. If target vehicle B that should have received the pre-authorization does not receive the pre-authorization due to signal delay or other factors, vehicle A can send an invitation to target vehicle B that has not received the pre-authorization through the on-board computer, and target vehicle B that accepts the invitation can automatically join the location sharing map. If the target vehicle B has not obtained pre-authorization and has not received a location sharing invitation from vehicle A after entering the map sharing area for a preset waiting time, the target vehicle B can search for the location sharing signal sent by vehicle A through the on-board computer, and send an application to vehicle A to join the location sharing map through the location sharing signal sent by vehicle A. At the same time, the application sent by vehicle B will also be displayed on the on-board display of vehicles C, D... that have joined the location sharing map, and vehicle A that initiates the sharing or vehicles C, D... that have joined the location sharing map will respond to vehicle B's application to join.
[0047] After joining the location sharing map, the location sharing map containing all vehicles joining the location sharing map is displayed from the perspective of the vehicle on the in-vehicle display of each of A, B, C, D, etc. During driving, if vehicle A needs to exchange information with vehicle B, vehicle A can click the icon of vehicle B through the in-vehicle display to view the distance between vehicle A and vehicle B, the specific location of vehicle B, and automatically calculate the driving time to meet vehicle B; a window for information exchange with vehicle B can also pop up to contact vehicle B through the in-vehicle computer, and this process does not require the use of any mobile communication device.
[0048] The calculation of the distance between object A and object B and the travel time required for the encounter is based on the fixed position information and movement information of the target, and is calculated taking into account at least one of the road conditions, traffic conditions, weather conditions and other factors.
[0049] It should be understood that the application of the vehicle location sharing method provided in the embodiment of the present application to the above-mentioned application scenario is merely an exemplary description and should not be understood as a limitation on the scenarios to which the method is applicable.
