[0025] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0026] This application embodiment provides a method for parking guidance in a parking lot, please refer to Figure 1 , which shows a schematic diagram of the implementation environment of the method provided in the embodiment of the present application. The implementation environment may include: a target terminal 11, a parking lot server 12, a ceiling light 13 and a distance sensor 14.

[0027] In a possible implementation, the parking lot server 12 detects whether each parking space in the parking lot is occupied by using the distance sensor 14. If there is an unoccupied parking space, the parking lot server 12 sends information about the unoccupied parking space to the target terminal, which is used to display controls and / or numbers corresponding to the vacant parking spaces in the parking lot layout displayed on the target terminal 11.

[0028] Optionally, the parking lot server 12 obtains the user parking space selection information, including: if the target terminal 11 receives information that a control corresponding to any vacant parking space is clicked, the information of the vacant parking space corresponding to the clicked control is used as the user parking space selection information, or, if the target terminal 11 receives voice information containing a number corresponding to any vacant parking space, the information of the vacant parking space corresponding to the number contained in the voice information is used as the user parking space selection information; after determining the user parking space selection information, the target terminal 11 sends the user parking space selection information to the parking lot server 12.

[0029] Exemplarily, in response to receiving the user's parking space selection information, the parking lot server 12 obtains the location of the vehicle from the target terminal 11, and determines the location of the first vacant parking space according to the correspondence between the number of the first vacant parking space or the control information and the location of the parking space. The parking lot server 12 determines the first parking driving route based on the location of the vehicle and the location of the first vacant parking space, and controls the ceiling light 13 corresponding to the first parking driving route to light up with a preset color.

[0030] In a possible implementation, the parking lot server 12 sends the first parking driving route to the target terminal, so as to display the first parking driving route in a preset color in the parking lot layout map displayed on the target terminal. The target terminal 11, the parking lot server 12, the ceiling light 13 and the distance sensor 14 establish a communication connection via a wired or wireless network.

[0031] Based on the above Figure 1 In the implementation environment shown, the present application embodiment provides a method for guiding parking in a parking lot. Figure 2 As shown, taking the method applied to a parking lot server as an example, the method includes steps 201 to 205.

[0032] In step 201, the parking lot server obtains a detection result of a first vacant parking space, and the detection result of the first vacant parking space is used to indicate whether there is a vacant parking space in the parking lot.

[0033] In a possible implementation, when the parking lot server detects that a vehicle enters the parking lot from any entrance of the parking lot, the detection result of the first vacant parking space is obtained, wherein the detection result of the first vacant parking space is used to indicate whether there is a vacant parking space in the parking lot. Optionally, the parking lot server obtains the detection result of the first vacant parking space, including: the parking lot server detects whether the parking space is occupied by a distance sensor above each parking space. If there is an unoccupied parking space, the detection result of the first vacant parking space indicates that there is a vacant parking space in the parking lot; if there is no unoccupied parking space, the detection result of the first vacant parking space indicates that there is no vacant parking space in the parking lot.

[0034] Optionally, a distance sensor is located above each parking space to detect the vertical distance from the distance sensor to the obstruction. Optionally, the obstruction may be a large obstacle, a small obstacle, and other vehicles, wherein the small obstacle is an obstacle that does not affect normal parking, and the large obstacle is an obstacle that affects normal parking.

[0035] Exemplarily, the distance sensor above each parking space detects whether the parking space is occupied, including: if the first distance detected by the distance sensor is less than the second distance from the distance sensor to the ground of the parking space, and the difference between the first distance and the second distance is greater than a preset difference, it is determined that the parking space corresponding to the distance sensor is occupied; if the difference between the first distance and the second distance is less than or equal to the preset difference, it is determined that the parking space corresponding to the distance sensor is not occupied. The second distance from the distance sensor to the ground of the parking space can be measured and determined in advance when the parking space is not occupied, and the preset difference can be determined according to the height of small obstacles that do not affect parking.

[0036] In step 202, in response to the detection result of the first vacant parking space indicating that there are vacant parking spaces in the parking lot, the parking lot server obtains user parking space selection information, and the user parking space selection information indicates that the user selects the first vacant parking space among the vacant parking spaces for parking.

[0037] Exemplarily, after obtaining the detection result of the first vacant parking space, in response to the detection result of the first vacant parking space indicating that there is a vacant parking space in the parking lot, the parking lot server obtains the user parking space selection information, wherein the user parking space selection information indicates that the user selects the first vacant parking space among the vacant parking spaces for parking. In a possible implementation, the parking lot server obtains the user parking space selection information, including: sending the vacant parking space information to the target terminal, for displaying the controls and / or numbers corresponding to the vacant parking spaces in the parking lot layout map displayed on the target terminal; receiving the information of the control corresponding to any vacant parking space being clicked as the user parking space selection information; or receiving the voice information containing the number corresponding to any vacant parking space as the user parking space selection information.

[0038] Optionally, a parking lot layout is displayed on a display screen of the target terminal, and controls and / or numbers corresponding to the available parking spaces are displayed in the parking lot layout, wherein the parking lot layout includes all driving routes and parking spaces in the parking lot. If the target terminal receives information that a control corresponding to any available parking space is clicked, the information of the available parking space corresponding to the clicked control is used as user parking space selection information; if the voice recognition device of the target terminal receives voice information including a number corresponding to any available parking space, the information of the available parking space corresponding to the number included in the voice information is used as user parking space selection information. The voice recognition device is located at the target terminal and parses and recognizes the user's voice command.

[0039] In step 203, in response to receiving the user's parking space selection information, the parking lot server obtains the location of the vehicle and the location of the first vacant parking space.

[0040] Exemplarily, after receiving the user's parking space selection information, the parking lot server obtains the location of the vehicle and the location of the first vacant parking space, including: the parking lot server obtains the location of the vehicle through the navigation device of the target terminal, and then based on the number or control information of the first vacant parking space, according to the correspondence between the number or control information of the first vacant parking space and the location of the parking space, determines the location of the first vacant parking space. Optionally, the target terminal includes a navigation system, and the real-time location of the vehicle can be obtained through the navigation system.

[0041] In step 204 , the parking lot server determines a first parking driving route based on the location of the vehicle and the location of the first vacant parking space.

[0042] In one possible implementation, after determining the vehicle position and the position of the first vacant parking space, the parking lot server determines the first parking driving route based on the vehicle position and the position of the first vacant parking space, including: the parking lot server determines the first parking driving route corresponding to the current vehicle position and the position of the first vacant parking space based on the vehicle position and the position of the first vacant parking space according to a preset correspondence between the vehicle position, the target parking space and the recommended driving route.

[0043] In step 205, the parking lot server controls the ceiling light corresponding to the first parking driving route to light up with a preset color.

[0044] In a possible implementation, after determining the first parking driving route, the parking lot server controls the ceiling lights corresponding to the first parking driving route to light up with a preset color. Exemplarily, ceiling lights are installed at a certain distance above all driving routes in the parking lot. The ceiling lights can emit different colors, and the switch state, color and lighting time of the ceiling lights are controlled by the parking lot server. Among them, the color of the ceiling lights on the parking driving routes of the same user is uniform, and the color of the ceiling lights on the parking driving routes of different users is different. Optionally, the preset color can be a common color assigned in a preset order, and it is necessary to ensure that the warning color is not included. Optionally, the interval distance between the ceiling lights can be set based on experience.

[0045] Optionally, while controlling the ceiling light corresponding to the first parking driving route to light up in a preset color, the parking lot server sends the first parking driving route to the target terminal, so as to display the first parking driving route in a preset color in the parking lot layout map displayed on the target terminal. In a possible implementation, displaying the first parking driving route in a preset color in the parking lot layout map displayed on the target terminal includes: in the parking lot layout map displayed on the display screen of the target terminal, setting the ceiling light of the road section corresponding to the first parking driving route to a preset color, so as to display to the user the driving route of the vehicle that is about to go to the first vacant parking space.

[0046] Exemplarily, after the ceiling lights corresponding to the first parking driving route are lit with a preset color, in response to the overlap of the first parking driving routes of different vehicles, the parking lot server controls the ceiling lights of the overlapping portion of the route to switch to a warning color, wherein the preset color does not include the warning color. Optionally, the warning color can be set empirically, for example, to red. In a possible implementation, after the ceiling lights corresponding to the first parking driving route are lit with a preset color, the parking lot server monitors the first parking driving routes of the remaining vehicles in the parking lot. If the first parking driving routes of different vehicles overlap, the ceiling lights corresponding to the overlapping section of the route are switched to a warning color, and the ceiling lights of the overlapping portion of the route are switched to a warning color in the parking lot layout diagram displayed on the target terminal.

[0047] In one possible implementation, while the vehicle is traveling along a route corresponding to a ceiling light of a preset color, in response to the vehicle entering a first vacant parking space, the ceiling light corresponding to the first parking route is controlled to be turned off; and / or in response to the vehicle not entering the first vacant parking space within a first preset time period, the ceiling light corresponding to the first parking route is controlled to be turned off.

[0048] In a possible implementation, when the vehicle is traveling along the route corresponding to the ceiling light of the preset color, the parking lot server continuously monitors the position of the vehicle. If it is detected that the position of the vehicle coincides with the position of the first vacant parking space, the vehicle is indicated to enter the first vacant parking space, and the parking lot server controls the ceiling light corresponding to the first parking route to turn off; if the position of the vehicle still does not coincide with the position of the first vacant parking space within the first preset time, the vehicle has not entered the first vacant parking space within the first preset time, and the parking lot server controls the ceiling light corresponding to the first parking route to turn off. Exemplarily, after the ceiling light corresponding to the first parking route is controlled to turn off, the display of the first parking route in the preset color on the display screen of the target terminal is canceled. Optionally, the first preset time can be set based on experience.

[0049] Optionally, while the vehicle is traveling along a route corresponding to a ceiling light of a preset color, in response to the vehicle entering a first vacant parking space, the parking lot server confirms that the first vacant parking space is occupied, obtains the position of a second vacant parking space closest to the first vacant parking space; determines a second parking route based on the vehicle's position and the position of the second vacant parking space; and controls the ceiling light corresponding to the second parking route to light up with a preset color for a second preset time period.

[0050] In one possible implementation, while the vehicle is traveling along a route corresponding to a ceiling light of a preset color, the parking lot server continuously monitors the occupancy status of a first vacant parking space. If, before the vehicle enters the first vacant parking space, it is confirmed that the first vacant parking space is occupied, the target terminal obtains a detection result of a second vacant parking space, wherein the detection result of the second vacant parking space is used to indicate whether there are any other vacant parking spaces in the parking lot in addition to the first vacant parking space.

[0051] Exemplarily, in response to the detection result of the second vacant parking space indicating that there are no other vacant parking spaces in the parking lot except the first vacant parking space, a prompt message indicating that there are no vacant parking spaces is displayed on the display screen of the target terminal; in response to the detection result of the second vacant parking space indicating that there are other vacant parking spaces in the parking lot except the first vacant parking space, the parking lot server confirms the second vacant parking space closest to the first vacant parking space, and obtains the location of the second vacant parking space closest to the first vacant parking space.

[0052] Optionally, after the location of the second vacant parking space is acquired, the parking lot server determines the second parking driving route corresponding to the current location of the vehicle and the location of the second vacant parking space based on the current location of the vehicle and the location of the second vacant parking space, according to the preset correspondence between the location of the vehicle, the target parking space and the recommended driving route, and then controls the ceiling light corresponding to the second parking driving route to light up with a preset color for a second preset time. Optionally, the second time can be set based on experience, and it is required to meet the second preset time that is greater than the first preset time. For example, the second preset time can be 5 minutes longer than the first preset time.

[0053] Combining the above methods, Figure 3 The parking lot layout diagram provided in the embodiment of the present application is used as an example for illustration. The execution subject may be a parking lot server. When a vehicle enters the parking lot from the entrance of the parking lot, in response to the existence of vacant parking spaces in the parking lot, the parking lot server obtains the user's parking space selection information and confirms that parking space No. 64 is the first vacant parking space. The parking lot server determines the first parking driving route based on the location of the vehicle and the location of the first vacant parking space, and then controls the ceiling lights corresponding to the first parking driving route to light up with a preset color, wherein the ceiling lights lit with the preset color are marked as in the parking lot layout diagram. The ceiling lights that are not turned on are marked with ○ in the parking lot layout diagram.

[0054] The embodiment of the present application allows the user to select an available parking space in the parking lot, and controls the ceiling lights on the parking route leading to the available parking space selected by the user to light up in a predetermined color, so that the user can directly obtain guidance on the parking route, allowing the vehicle to reach the parking space more conveniently, alleviating the problem of vehicle congestion in the parking lot, reducing the time spent looking for parking spaces, and solving the problem of users being unable to find available parking spaces in the parking lot.
