Description

Technical Field

[0001] This application relates to the technical field of vehicle warning, and particularly to a method, a system and an electronic device for parking lot door opening collision warning. Background Art

[0002] Currently, the number of vehicles in society is increasing, and the size of vehicles is getting larger. Some parking lots have reduced their sizes to increase the number of parking spaces. At this time, when the vehicle owner parks the car, it is easy to have problems such as not being able to open the door or colliding with adjacent vehicles after parking, resulting in economic losses. Therefore, it is of great significance to warn of door opening collisions.

[0003] Currently, in the market, the door opening collision warnings configured in vehicles are all to warn of the situations of oncoming vehicles and pedestrians behind when opening the door while parking by the roadside, avoiding collisions with oncoming pedestrians and vehicles when opening the door.

[0004] However, due to obstacles and other reasons, there are problems such as insufficient door opening space for the vehicle owner after parking, resulting in the door being unable to open or the vehicle being damaged due to door collision. Summary of the Invention

[0005] This application provides a method, a system and an electronic device for parking lot door opening collision warning, which are used to solve the problem that the vehicle owner cannot open the door or the vehicle is damaged due to collision when opening the door after parking in the parking space due to obstacles and other reasons. The specific implementation solutions are as follows:

[0006] In a first aspect, this application provides a method for parking lot door collision warning, and the method includes:

[0007] When the vehicle detects a parking space, scan the first obstacle and the second obstacle on both sides of the parking space;

[0008] Calculate the minimum distance between the first obstacle and the second obstacle;

[0009] Determine whether the vehicle width value after the vehicle door is opened is less than or equal to the minimum distance;

[0010] If so, output a prompt message indicating that the parking space is an available parking space;

[0011] If not, output an alarm message indicating that the parking space is an unavailable parking space.

[0012] By scanning the first obstacle and the second obstacle on both sides of the parking space, calculating the minimum interval distance between the first obstacle and the second obstacle, and determining whether the vehicle width value after the vehicle door is opened is less than or equal to the minimum interval distance, collision warning when the vehicle door is opened is realized. By this method, risks such as insufficient door opening space after parking are identified in advance, and vehicle losses caused by the inability to open the door or door collision are reduced.

[0013] In a possible design, determining whether the vehicle width value after the vehicle door is opened is less than or equal to the minimum interval distance includes:

[0014] Detecting whether there is a person at a specified position;

[0015] If there is, determining whether the vehicle width value after the vehicle door is opened on both sides is less than or equal to the minimum interval distance;

[0016] If not, determining whether the vehicle width value after the vehicle door is opened on one side is less than or equal to the minimum interval distance.

[0017] By comparing the vehicle width value after the vehicle door is opened on both sides or one side with the minimum interval distance, the problem that the vehicle door cannot be opened on both sides or one side after parking in the parking space is avoided, and at the same time, the risk of vehicle loss caused by collision after the vehicle door is opened on both sides or one side is avoided.

[0026] If receiving the command information that the vehicle owner does not fully open the vehicle doors, determine whether the vehicle width value after the vehicle doors are opened by the minimum number of levels on one side of the vehicle is less than or equal to the minimum interval distance.

[0027] By comparing the vehicle width value after the vehicle doors are fully opened on one side of the vehicle or after the vehicle doors are opened by the minimum number of levels on one side of the vehicle with the minimum interval distance, the problem that the vehicle doors on one side cannot be fully opened or cannot be opened by the minimum number of levels after the vehicle parks in the parking space is avoided, and at the same time, the risk of vehicle loss caused by collision after the vehicle doors are fully opened on one side or after the vehicle doors are opened by the minimum number of levels is avoided.

[0028] In a possible design, after outputting the warning information that the parking space is an unavailable parking space, it further includes:

[0060] In order to make the objectives, technical solutions and advantages of this application clearer, the following will further describe this application in detail with reference to the accompanying drawings. The specific operation methods in the method embodiments can also be applied to the device embodiments or system embodiments. It should be noted that in the description of this application, "a plurality of" is understood as "at least two". "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B may represent: A exists alone, A and B exist simultaneously, and B exists alone these three situations. A is connected to B, which may represent: A is directly connected to B and A is connected to B through C these two situations. In addition, in the description of this application, words such as "first" and "second" are only used for the purpose of distinguishing descriptions, and cannot be understood as indicating or implying relative importance, nor can they be understood as indicating or implying an order.

[0061] The following will describe the embodiments of this application in detail with reference to the accompanying drawings.

[0062] Currently, the door opening collision warnings configured for market vehicles are all for warning of the situations of oncoming vehicles and pedestrians behind when opening the door while parking by the roadside, avoiding the occurrence of situations such as collision with oncoming pedestrians and vehicles when opening the door. However, due to obstacles and other reasons, there are problems such as insufficient door opening space for the vehicle owner after parking, resulting in the door being unable to open or the vehicle being damaged due to door collision.

[0063] Therefore, the embodiments of the present application provide a method for warning of door-opening collisions in a parking lot. By scanning the first obstacle and the second obstacle on both sides of the target parking space, calculating the minimum distance between the first obstacle and the second obstacle, and determining whether the vehicle width value after the vehicle door is opened is less than or equal to the minimum distance, the collision warning when the vehicle door is opened is realized. By this method, risks such as insufficient door-opening space after the vehicle owner parks can be identified in advance, and vehicle losses caused by the inability to open the door or door collisions can be reduced.

[0064] Refer to Figure 1 The following is a flowchart of a method for warning of door-opening collisions in a parking lot provided by the embodiments of the present application. The method includes:

[0065] S1. When the vehicle detects a parking space, scan the first obstacle and the second obstacle on both sides of the parking space;

[0066] Specifically, when the vehicle drives into the parking lot and detects a parking space, the vehicle scans the first obstacle and the second obstacle on both sides of the parking space through an in-vehicle radar, a camera, and a supporting controller.

[0067] Obtain the information of the first obstacle and the information of the second obstacle.

[0068] It should be noted here that the first obstacle and the second obstacle are respectively the objects closest to the parking space on both sides of the parking space.

[0069] In the embodiments of the present application, the information content of the first obstacle and the second obstacle obtained may be the information content about the size of the first obstacle and the size of the second obstacle, or the information content about the coordinates of the first obstacle and the coordinates of the second obstacle. The specific information content is not limited in the embodiments of the present application.

[0070] For example, as Figure 2 shown in the vehicle diagram in the parking lot, when the vehicle drives into the parking lot to prepare for parking, it will automatically detect the parking space. After detecting an empty parking space, it scans the first obstacle and the second obstacle on both sides of the empty parking space through the in-vehicle radar, camera, and supporting controller equipped with the vehicle, and obtains the coordinate information of the first obstacle and the coordinate information of the second obstacle.

[0071] S2. Calculate the minimum distance between the first obstacle and the second obstacle;

[0072] Specifically, after obtaining the information content of the first obstacle and the second obstacle scanned in step S1, calculate the minimum distance between the first obstacle and the second obstacle through the calculation method of the minimum distance.

[0073] It should be noted here that in the embodiments of the present application, the calculation method of the minimum spacing distance can be to calculate the minimum spacing distance based on the calculation method of the closest point between the first obstacle and the second obstacle, or to calculate the minimum spacing distance according to the sum of the closest distances between the parking space and the first obstacle and the closest distance between the parking space and the second obstacle. The specific calculation method is not limited in the embodiments of the present application.

[0074] For example, in the vehicle diagram as Figure 2 shown, after the vehicle obtains the coordinate information of the first obstacle and the coordinate information of the second obstacle, it records the coordinates of the point closest to each other between the first obstacle and the second obstacle, which are respectively recorded as A(10,5) and B(15,5). By using the distance calculation formula for coordinate points, the distance between points A and B is calculated to be 5 meters. Therefore, the minimum spacing distance between the first obstacle and the second obstacle is 5 meters.

[0075] S3. Determine whether the vehicle width value after the vehicle door is opened is less than or equal to the minimum spacing distance;

[0076] If the vehicle width value after the vehicle door is opened is less than or equal to the minimum spacing distance, execute step S4;

[0077] If the vehicle width value after the vehicle door is opened is not less than or equal to the minimum spacing distance, execute step S5.

[0078] S4. Output a prompt message indicating that the parking space is an available parking space;

[0079] After determining that the above vehicle width value is less than or equal to the above minimum spacing distance, determine the number of door levels that the vehicle can open after parking in the parking space as required by the vehicle owner. At this time, output a prompt message indicating that the parking space is an available parking space.

[0080] For example, in the vehicle diagram as Figure 3 shown, there is no person in the co-pilot position of the vehicle. The vehicle receives the command information for the vehicle owner not to fully open the door, and the vehicle width value after the vehicle door is opened unilaterally to the minimum level is less than the minimum spacing distance. It is determined that the vehicle owner can open the minimum door level after parking in this parking space. At this time, output a command message indicating that the parking space is an available parking space.

[0081] S5. Output an alarm message indicating that the parking space is an unavailable parking space;

[0082] Specifically, after determining that the above vehicle width value is greater than the above minimum spacing distance, receive the command information of whether the vehicle owner changes the parking space;

[0083] If the command information of the vehicle owner to change the parking space is received, scan the next parking space and continue to execute steps S1, S2, S3, S4, and S5;

[0084] If the instruction information for the vehicle owner not to change the parking space is received, a prompt message for starting automatic parking is output.

[0085] For example, as Figure 3 shown in the vehicle diagram, there is no person in the co-pilot position of the vehicle. The vehicle width value after the vehicle door is opened unilaterally by the minimum number of levels is less than the minimum interval distance, but the vehicle width value after the vehicle door is opened unilaterally by two levels is greater than the minimum interval distance. At this time, the instruction information for the vehicle owner not to change the parking space is received, a prompt message for starting automatic parking is output, and at the same time, an alarm message indicating a collision risk when the vehicle door is opened by two levels is output.

[0086] Through the above method, a solution for the vehicle door not being able to open or a collision occurring after the vehicle door is opened is provided for the vehicle owner, reducing the economic loss for the vehicle owner.

[0087] In the embodiment of the present application, the vehicle width value after the vehicle door is opened is divided into four cases: the vehicle width value after both vehicle doors are fully opened, the vehicle width value after both vehicle doors are opened by the minimum number of levels, the vehicle width value after one vehicle door is fully opened, and the vehicle width value after one vehicle door is opened by the minimum number of levels.

[0088] Case 1:

[0089] Through the personnel scanning method equipped on the vehicle, it is detected that there is a person at the specified position, and the instruction information for the vehicle owner to fully open the vehicle door is received. At this time, the vehicle width value after the vehicle door is opened is the vehicle width value after both vehicle doors are fully opened;

[0090] Determine whether the vehicle width value after both vehicle doors are fully opened is less than or equal to the above minimum interval distance;

[0091] If so, output a prompt message indicating that the parking space is an available parking space;

[0092] If not, output an alarm message indicating that the parking space is an unavailable parking space.

[0093] In the embodiment of the present application, the personnel scanning method can be a scanning method based on a vehicle camera or a scanning method according to infrared thermal imaging. In the embodiment of the present application, the specific scanning method is not limited.

[0094] It should be noted here that in the embodiment of the present application, the specified position is the co-pilot position of the vehicle.

[0095] For example, as Figure 2In the vehicle diagram shown, there is a person in the co-driver's position of the vehicle, and the instruction information to fully open the vehicle doors is received. The vehicle width value after both sides of the vehicle doors are fully opened is 4 meters. Compared with the minimum interval distance of 5 meters calculated based on the closest distance between the obstacles on both sides of the parking space, it is determined that the vehicle width value is less than the minimum interval distance. At this time, a prompt message indicating that the parking space is available is output.

[0096] By the above method, the problem that the vehicle doors cannot be fully opened on both sides after the vehicle parks in the parking space or the risk of vehicle damage caused by collision when the vehicle doors are fully opened on both sides is avoided.

[0097] Case Two:

[0098] Through the personnel scanning method equipped on the vehicle, it is detected that there is a person at the specified position, and the instruction information not to fully open the vehicle doors is received. At this time, the vehicle width value after the vehicle doors are opened is the vehicle width value after the minimum number of opening levels of both sides of the vehicle doors;

[0099] Determine whether the vehicle width value after the minimum number of opening levels of both sides of the vehicle doors is less than or equal to the minimum interval distance;

[0100] If so, output a prompt message indicating that the parking space is available;

[0101] If not, output an alarm message indicating that the parking space is unavailable.

[0102] For example, as Figure 2 In the vehicle diagram shown, there is a person in the co-driver's position of the vehicle, and the instruction information not to fully open the vehicle doors is received. The vehicle width value after the minimum number of opening levels of both sides of the vehicle doors is 2.5 meters. Compared with the minimum interval distance of 5 meters calculated based on the closest distance between the obstacles on both sides of the parking space, it is determined that the vehicle width value is less than the minimum interval distance. At this time, a prompt message indicating that the parking space is available is output.

[0103] By the above method, the problem that the vehicle doors cannot be opened to the minimum number of levels on both sides after the vehicle parks in the parking space or the risk of vehicle damage caused by collision when the vehicle doors are opened to the minimum number of levels on both sides is avoided.

[0104] Case Three:

[0105] Through the personnel scanning method equipped on the vehicle, it is detected that there is no person at the specified position, and the instruction information to fully open the vehicle doors is received. At this time, the vehicle width value after the vehicle doors are opened is the vehicle width value after one side of the vehicle doors is fully opened;

[0106] Determine whether the vehicle width value after one side of the vehicle doors is fully opened is less than or equal to the minimum interval distance;

[0107] If so, output a prompt message indicating that the parking space is available;

[0108] Otherwise, output an alarm message indicating that the parking space is unavailable.

[0109] For example, in the vehicle diagram Figure 2 as shown, there is no person in the co-driver's position of the vehicle, and the instruction information to fully open the vehicle door is received. The vehicle width value after one-sided full opening of the vehicle door is 3 meters. Compared with the minimum interval distance of 5 meters calculated based on the closest distance between the obstacles on both sides of the parking space, it is determined that the vehicle width value is less than the minimum interval distance. At this time, output a prompt message indicating that the parking space is available.

[0110] Through the above method, the problem that the vehicle door cannot be fully opened on one side after the vehicle parks in the parking space or the risk of vehicle damage caused by collision after one-sided full opening of the vehicle door is avoided.

[0111] Situation 4:

[0112] It is detected through the personnel scanning method equipped in the vehicle that there is no person at the specified position, and the instruction information for the vehicle owner not to fully open the vehicle door is received. At this time, the vehicle width value after the vehicle door is opened is the vehicle width value after the minimum number of levels of one-sided opening of the vehicle door;

[0113] Determine whether the vehicle width value after the minimum number of levels of one-sided opening of the vehicle door is less than or equal to the minimum interval distance;

[0114] If so, output a prompt message indicating that the parking space is available;

[0115] Otherwise, output an alarm message indicating that the parking space is unavailable.

[0116] For example, in the vehicle diagram Figure 2 as shown, there is no person in the co-driver's position of the vehicle, and the instruction information for the vehicle owner not to fully open the vehicle door is received. The vehicle width value after the minimum number of levels of one-sided opening of the vehicle door is 2 meters. Compared with the minimum interval distance of 5 meters calculated based on the closest distance between the obstacles on both sides of the parking space, it is determined that the vehicle width value is less than the minimum interval distance. At this time, output a prompt message indicating that the parking space is available.

[0117] Through the above method, the problem that the vehicle door cannot be opened to the minimum number of levels on one side after the vehicle parks in the parking space or the risk of vehicle damage caused by collision after one-sided opening of the vehicle door to the minimum number of levels is avoided.

[0118] The parking lot door opening collision warning method proposed in this application realizes the warning when the door is opened by scanning the obstacles on both sides of the target parking space and calculating and judging whether the vehicle width value after the vehicle door is opened is less than or equal to the minimum interval distance between the obstacles. Through this method, risks such as insufficient door opening space after the vehicle owner parks can be identified in advance, reducing vehicle losses caused by the door being unable to open or the door colliding.

[0119] In addition, this method is particularly useful for vehicle owners with less proficient driving skills or when driving an unfamiliar vehicle; at the same time, the implementation cost is low, and it can be implemented based on the relevant hardware (controller, radar, camera, etc.) of the existing automatic parking function and the independently developed function software, without increasing the hardware cost or only increasing a small amount of hardware cost.

[0120] The technical solution of this application will be further described below in combination with the specific application process.

[0121] As Figure 4 shown in the schematic diagram of the processing process of the parking lot door opening collision warning, first, after the vehicle finds a parking space in the parking lot, it scans the objects on both sides of the parking space;

[0122] Calculate the minimum interval distance between the above two objects;

[0123] Judge whether the vehicle width value after the vehicle stops and opens the door in the above parking space is less than or equal to the minimum interval distance;

[0124] If so, output a prompt message indicating that parking is allowed;

[0125] If not, receive the command information on whether the vehicle owner changes the parking space;

[0126] If the command information on changing the parking space by the vehicle owner is received, scan the next parking space and continue to execute the above operations;

[0127] If the command information on not changing the parking space by the vehicle owner is received, output a prompt message to turn on automatic parking.

[0128] Through the above processing process of the parking lot door opening collision warning, by scanning the objects on both sides of the parking space, calculating the minimum interval distance between the objects, and judging whether the vehicle width value after the vehicle door is opened is less than or equal to the minimum interval distance, the warning of the parking lot door opening collision is realized. Through this method, risks such as insufficient door opening space after the vehicle owner parks can be identified in advance, reducing vehicle losses caused by the door being unable to open or the door colliding.

[0129] Based on the same inventive concept, an embodiment of this application also provides a parking lot door opening collision warning system, as Figure 5The following is a schematic structural diagram of a parking lot door opening collision warning system provided by the present application. The system includes:

[0130] A scanning module 501, configured to scan a first obstacle and a second obstacle on both sides of the parking space when the vehicle detects the parking space;

[0131] A calculation module 502, configured to calculate the minimum interval distance between the first obstacle and the second obstacle;

[0132] A processing module 503, configured to determine whether the vehicle width value after the vehicle door is opened is less than or equal to the minimum interval distance;

[0133] If so, output a prompt message indicating that the parking space is an available parking space;

[0134] If not, output an alarm message indicating that the parking space is an unavailable parking space.

[0135] In a possible design, the processing module 503 is specifically configured to detect whether there is a person at a specified position;

[0136] If there is, receive the command information on whether the vehicle owner fully opens the door;

[0137] If receiving the command information that the vehicle owner fully opens the door, determine whether the vehicle width value after the vehicle door is fully opened on both sides is less than or equal to the minimum interval distance;

[0138] If receiving the command information that the vehicle owner does not fully open the door, determine whether the vehicle width value after the vehicle door is opened at the minimum number of levels on both sides is less than or equal to the minimum interval distance;

[0139] If not, receive the command information on whether the vehicle owner fully opens the door;

[0140] If receiving the command information that the vehicle owner fully opens the door, determine whether the vehicle width value after the vehicle door is fully opened on one side is less than or equal to the minimum interval distance;

[0141] If receiving the command information that the vehicle owner does not fully open the door, determine whether the vehicle width value after the vehicle door is opened at the minimum number of levels on one side is less than or equal to the minimum interval distance.

[0142] In a possible design, the processing module 503 is specifically configured to receive the command information on whether the vehicle owner changes the parking space;

[0143] If receiving the command information that the vehicle owner changes the parking space, scan the next parking space;

[0144] If receiving the command information that the vehicle owner does not change the parking space, output a prompt message for starting automatic parking.

[0145] Based on the same inventive concept, an electronic device is further provided in an embodiment of the present application. The electronic device can implement the functions of the aforementioned parking lot door opening collision warning system. Refer to Figure 6 , the electronic device includes:

[0146] At least one processor 601, and a memory 602 connected to the at least one processor 601. In the embodiment of the present application, the specific connection medium between the processor 601 and the memory 602 is not limited. Figure 6 In [reference], it is taken as an example that the processor 601 and the memory 602 are connected through a bus 600. The bus 600 is Figure 6 shown by a thick line in [reference]. The connection manners between other components are only for illustrative purposes and are not limited thereto. The bus 600 can be divided into an address bus, a data bus, a control bus, etc. For the convenience of representation, Figure 6 it is only shown by a thick line in [reference], but it does not mean that there is only one bus or one type of bus. Alternatively, the processor 601 can also be called a controller, and there is no limitation on the name.

[0147] In the embodiment of the present application, the memory 602 stores instructions executable by the at least one processor 601. By executing the instructions stored in the memory 602, the at least one processor 601 can execute the parking lot door opening collision warning method discussed above. The processor 601 can implement Figure 6 the functions of each module in the system shown.

[0148] Among them, the processor 601 is the control center of the device. It can connect various parts of the entire control device through various interfaces and lines. By running or executing the instructions stored in the memory 602 and calling the data stored in the memory 602, various functions of the device and process data, so as to monitor the device as a whole.

[0149] In a possible design, the processor 601 may include one or more processing units. The processor 601 may integrate an application processor and a modem processor. Among them, the application processor mainly processes the operating system, user interface, application programs, etc., and the modem processor mainly processes wireless communication.
