[Technical field]

[0001] The present invention relates to an information processing device and an information processing method. [Background technology]

[0002] An autonomous driving device has been proposed that acquires weather information around a destination, determines whether or not parking in a parking lot around the destination can be done autonomously based on the presence or absence of a roof in the parking lot and the weather information, and presents the result of the determination of whether or not parking can be done to the user (see Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2018-105814 A Summary of the Invention [Problem to be solved by the invention]

[0004] The technology described in Patent Document 1 determines whether parking is possible based on weather information, but weather is only one of the factors that can affect parking. In other words, the technology described in Patent Document 1 cannot determine whether parking is possible while taking into account factors other than weather, and the result of the determination of whether parking is possible may change depending on factors other than weather.

[0005] The present invention has been made in consideration of the above problems, and an object of the present invention is to provide an information processing device and an information processing method that are capable of determining whether parking is possible by taking into account various factors that may affect parking. [Means for solving the problem]

[0006] In order to solve the above-mentioned problems, an information processing device and information processing method according to one embodiment of the present invention determine whether the factor that caused the vehicle to fail to park in a parking lot is a variable factor based on factor data indicating the factor, and if it is determined that the factor is not a variable factor, it determines that parking in the parking lot is not recommended. Effect of the Invention

[0007] According to the present invention, it is possible to determine whether parking is possible by taking into consideration various factors that may affect parking, and it is possible to make a more accurate determination as to whether parking is possible. [Brief description of the drawings]

[Diagram 2] FIG. 2 is a flowchart showing the process (registration process) of the information processing device according to one embodiment of the present invention. [Diagram 3] FIG. 3 is a flowchart showing the process (determination process) of the information processing device according to one embodiment of the present invention. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] Next, an embodiment of the present invention will be described in detail with reference to the drawings. In the description, the same parts are designated by the same reference numerals and duplicated explanations will be omitted.

[0010] [Configuration of information processing device] A configuration example of an information processing device 1 according to this embodiment will be described with reference to Fig. 1. The information processing device 1 may be mounted on a vehicle or installed outside the vehicle. In the following, the vehicle according to this embodiment will be described as a vehicle capable of performing automatic parking, but is not limited thereto.

[0011] 1, the information processing device 1 includes a parking lot data receiving unit 21, a factor data receiving unit 22, a storage unit 25, and a controller 100. In addition, the information processing device 1 may include a presentation unit 300.

[0012] The parking lot data receiving unit 21 is connected to the parking lot identification unit 11 and the controller 100, and receives parking lot data for identifying a parking lot from the parking lot identification unit 11. The parking lot identification unit 11 generates information for identifying a parking lot where parking was successful or a parking lot where parking was unsuccessful as a result of an attempt to park a vehicle, as parking lot data. For example, the parking lot data includes information such as the location information of the parking lot or a unique number linked to the parking lot in a database. The parking lot data generated by the parking lot identification unit 11 is input to the parking lot data receiving unit 21.

[0013] In addition to the parking lot data generated by the parking lot identification unit 11, the parking lot data reception unit 21 may also receive, as parking lot data, information that identifies a parking lot where the vehicle is scheduled to be parked.

[0014] The parking lot data receiving unit 21 transmits the received parking lot data to the controller 100. Alternatively, the parking lot data receiving unit 21 may transmit the received parking lot data to the storage unit 25, which will be described later.

[0015] The factor data receiving unit 22 is connected to the parking assistance device 12 and the controller 100, and receives factor data from the parking assistance device 12. When the parking assistance device 12 attempts to park the vehicle and determines whether parking has been successful or unsuccessful, the parking assistance device 12 generates, as factor data, information specifying whether parking has been successful or unsuccessful, and information specifying the cause of the parking failure if parking has failed. For example, the factor data may include tag information indicating that a camera mounted on the vehicle cannot capture an image of part of the surroundings of the vehicle when parking.

[0016] The cause data may also include tag information that identifies the reason why some of the surroundings of the vehicle could not be captured when parked (such as water droplets on the camera lens surface due to bad weather, or part of the camera's imaging element being saturated due to backlight, etc.).

[0017] Furthermore, the factor data may include tag information indicating that when the vehicle was parked in a parking lot, there was an object in the parking lot or in the vehicle's driving route to the parking lot that may interfere with the vehicle's driving, or tag information indicating that the road surface shape of the parking lot or in the vehicle's driving route to the parking lot may interfere with the vehicle's driving.

[0018] In addition, the cause data may be generated based on the results of a user who is in the vehicle or around the vehicle checking and inputting the status of the vehicle and the parking lot when the vehicle fails to park.

[0019] In addition to the tag information described above, the factor data may also include supplementary information describing the conditions at the time of parking, such as the time (date) and time period (time) when parking was attempted, and weather information around the parking lot when parking was attempted (weather information for the area in which the parking lot is located).

[0020] The factor data receiving unit 22 transmits the factor data received from the parking assistance device 12 to the controller 100. Alternatively, the factor data receiving unit 22 may transmit the received factor data to a storage unit 25, which will be described later.

[0021] The storage unit 25 is connected to the controller 100, and stores the parking lot data received by the parking lot data receiving unit 21 and the factor data received by the factor data receiving unit 22. The storage unit 25 may store the received data (parking lot data, factor data) for a predetermined time. In other words, the stored data may be held by the storage unit 25 for a predetermined time after it is stored, and may be deleted after the predetermined time has elapsed after it is stored.

[0022] In addition, the storage unit 25 may store, in association with the parking lot data, history data indicating whether or not parking has been successful in a parking lot identified by the parking lot data.

[0023] The controller 100 is a general-purpose computer including a CPU (Central Processing Unit), a memory, a storage device, an input / output unit, etc. The controller 100 is connected to a presentation unit 300 and an information terminal 400.

[0024] A computer program for causing the controller 100 to function as the information processing device 1 is installed in the controller 100. By executing the computer program, the controller 100 functions as a plurality of information processing circuits included in the information processing device 1.

[0025] Although an example is shown here in which the multiple information processing circuits of the information processing device 1 are realized by software, it is of course possible to configure the information processing circuits by preparing dedicated hardware for executing each information process described below. Also, the multiple information processing circuits may be configured by individual hardware.

[0026] The controller 100 includes a factor determining unit 110, a parking possibility determining unit 120, and a transmitting unit 130 as a plurality of information processing circuits.

[0027] The factor determination unit 110 determines whether parking the vehicle in the parking lot was successful or unsuccessful based on the factor data. Then, the factor determination unit 110 determines whether the factor that caused the vehicle to fail to park in the parking lot is a variable factor. For example, the factor determination unit 110 determines that the factor is a "variable factor" when the tag information included in the factor data is predetermined tag information. More specifically, the factor determination unit 110 may determine that the factor is a "variable factor" when the tag information is tag information indicating "unable to capture an image of part of the surroundings of the vehicle when parking."

[0028] The factor determination unit 110 may determine that a factor is a "fixed factor" when the tag information indicates that "an object that may interfere with the vehicle's travel" or "the road surface shape of the vehicle's travel path may interfere with the vehicle's travel."

[0029] Additionally, the factor determination unit 110 may determine whether or not there is a correlation between the tag information and supplemental information such as the time (year / month / date) when parking was attempted, the time period (time), and weather information around the parking lot when parking was attempted, based on a plurality of factor data stored and accumulated in the memory unit 25. The factor determination unit 110 may determine that a factor related to tag information determined to have a correlation with the supplemental information is a variable factor.

[0030] When there is a correlation between the tag information and the supplementary information, it is considered that parking of the vehicle may be successful or unsuccessful depending on the situation indicated by the supplementary information. In other words, the factor represented by the tag information that is found to be correlated with the supplementary information can be said to be variable. Therefore, the factor related to the tag information that is determined to be correlated with the supplementary information is determined to be a variable factor.

[0031] The factor determining section 110 may determine whether or not a factor is a fluctuation factor based on factor analysis using machine learning, other than correlation analysis between tag information and supplemental information.

[0032] The result of the determination by the factor determination unit 110 is stored in the storage unit 25 in association with the parking lot data and the factor data.

[0033] For example, the factor determination unit 110 may classify a parking lot identified by the received parking lot data as a parking lot where parking is possible when parking is successful.

[0034] In addition, in the event of a parking failure, the factor determination unit 110 may classify the parking lot identified by the parking lot data into either a parking lot with a fixed factor or a parking lot with a variable factor, depending on whether the factor for the failure is a fixed factor or a variable factor.

[0035] Furthermore, when parking fails, if it cannot be determined whether the cause of the failure is a fixed factor or a variable factor, the factor determination unit 110 may classify the cause of the parking failure as unknown. An example of a case where it cannot be determined whether the cause of the failure is a fixed factor or a variable factor is, for example, a case where parking is interrupted due to a system failure during automatic parking.

[0036] The parking lot classification results obtained by the factor determination unit 110 are stored in the storage unit 25 in association with the parking lot data and the factor data.

[0037] The parking possibility determination unit 120 determines whether parking in the parking lot identified by the parking lot data is recommended. For example, the parking possibility determination unit 120 refers to the storage unit 25 and extracts factor data, a determination result, and a classification result associated with the parking lot data. When the determination result is that "the factor is a variable factor," the parking possibility determination unit 120 determines that parking in the parking lot identified by the parking lot data is not recommended.

[0038] In addition, when the determination result is that "the factor is a variable factor," the parking feasibility determination unit 120 may determine whether or not a situation occurs in which a factor related to the factor data will occur in the parking lot identified by the parking lot data.

[0039] Here, the parking feasibility determination unit 120 may refer to supplementary information included in the factor data stored at the time of past parking, and determine whether or not the situation is such that a factor will occur based on whether or not the situation at the time of past parking represented by the supplementary information matches the current parking lot situation.

[0040] For example, the parking feasibility determination unit 120 may determine whether or not a situation in which a factor will occur in the parking lot is present based on the time of year or time of day when parking is performed, or may determine whether or not a situation in which a factor will occur in the parking lot is present based on the weather in the area in which the parking lot is located.

[0041] Furthermore, when the determination result is that "the factor is a fixed factor", the parking possibility determination unit 120 may determine that parking in the parking lot identified by the parking lot data is not recommended.

[0042] In addition, the parking feasibility determination unit 120 may calculate the percentage of successful parking in a parking lot based on the history data stored in the memory unit 25 (data indicating whether or not parking was successful in a parking lot identified by the parking lot data).

[0043] The transmission unit 130 transmits to the presentation unit 300 or the information terminal 400 the determination result by the parking possibility determination unit 120 regarding whether parking in the parking lot is recommended or not, and the rate of successful parking in the parking lot.

[0044] The presentation unit 300 is, for example, a terminal mounted on a vehicle or a user's terminal. The presentation unit 300 presents information such as the determination result by the parking feasibility determination unit 120 and the rate of successful parking in the parking lot to the user by light or sound via a display or a speaker.

[0045] For example, the presentation unit 300 may present a parking lot in association with a rate at which parking was successful at the parking lot. Furthermore, when presenting information about a plurality of parking lots, the presentation unit 300 may present a parking lot with a higher rate at which parking was successful with a higher priority.

[0046] The information terminal 400 is, for example, a terminal mounted on a vehicle or a user's terminal. The information terminal 400 transmits parking lot data to the information processing device 1 and receives a determination result indicating whether parking in a parking lot identified by the transmitted parking lot data is recommended or not. The information terminal 400 may include a notification unit that notifies the user of the received determination result. The configuration of the notification unit may be the same as that of the presentation unit 300 described above.

[0047] [Processing procedure of information processing device (registration process)] Next, a procedure related to the registration process among the processes of the information processing device 1 according to this embodiment will be described with reference to the flowchart of Fig. 2. The process of the information processing device 1 shown in Fig. 2 is started after the parking assistance device 12 attempts to park the vehicle and determines whether parking has been successful or unsuccessful.

[0048] First, in step S101, the parking lot data receiving unit 21 receives parking lot data, and the factor data receiving unit 22 receives factor data.

[0049] In step S103, the factor determining unit 110 determines whether parking of the vehicle in the parking lot has been successful or unsuccessful, based on the factor data.

[0050] If it is determined that parking has been successful (YES in step S103), in step S105, the factor determination unit 110 classifies the parking lot identified by the received parking lot data as a parking lot where parking is possible.

[0051] If it is determined that parking has failed (NO in step S103), in step S107, the factor determination unit 110 determines whether or not the factor of the failure is due to a fixed factor, based on the factor data.

[0052] If it is determined that the cause of the failure is due to a fixed cause (YES in step S107), in step S109, the cause determination unit 110 classifies the parking lot identified by the received parking lot data as a parking lot having a fixed cause.

[0053] If it is determined that the cause of failure is not due to a fixed factor (NO in step S107), in step S111, the factor determination unit 110 determines whether the cause of failure is due to a variable factor based on the factor data.

[0054] If it is determined that the cause of the failure is due to a variable factor (YES in step S111), in step S113, the factor determination unit 110 classifies the parking lot identified by the received parking lot data as a parking lot having a variable factor.

[0055] If it is determined that the failure is not due to a variable factor (NO in step S111), in step S115, the factor determination unit 110 classifies the cause of the parking failure as unknown. For example, the factor determination unit 110 classifies the case as a system failure occurring during automatic parking.

[0056] After the processes of steps S105, S109, S113, and S115, the registration process ends.

[0057] [Processing procedure of information processing device (determination process)] Next, a procedure related to the determination process among the processes of the information processing device 1 according to this embodiment will be described with reference to the flowchart of Fig. 3. When there are multiple candidates for parking lots where the parking assistance device 12 can park the vehicle, the process of the information processing device 1 shown in Fig. 3 is executed sequentially for each candidate.

[0058] First, in step S201, the parking lot data acceptance unit 21 accepts parking lot data.

[0059] In step S203, the parking possibility determination unit 120 refers to the storage unit 25, acquires factor data associated with the parking lot data, and acquires information on factors that may affect parking in the parking lot identified by the parking lot data.

[0060] In step S205, it is determined whether there are any factors that may affect parking in the parking lot identified by the parking lot data.

[0061] If it is determined that there is no factor (NO in step S205), in step S213, the parking possibility determination unit 120 determines that parking in the parking lot specified by the parking lot data is recommended.

[0062] If it is determined that there is a factor (YES in step S205), in step S207, the parking possibility determination unit 120 determines whether or not the acquired factor is a fixed factor.

[0063] If it is determined that the cause is a fixed cause (YES in step S207), in step S215, the parking possibility determination unit 120 determines that parking in the parking lot identified by the parking lot data is not recommended.

[0064] If it is determined that the factor is not a fixed factor (NO in step S207), in step S209, the parking possibility determination unit 120 estimates the situation of the parking lot specified by the parking lot data. For example, the situation of the parking lot is estimated based on the time or time zone when parking is performed, weather information in the area where the parking lot is located, and the like.

[0065] In step S211, the parking possibility determination unit 120 determines whether or not a situation in which a variable factor will occur occurs in the parking lot identified by the parking lot data.

[0066] If it is determined that the situation is one in which a variable factor will occur (YES in step S211), then in step S215, the parking feasibility determination unit 120 determines that parking in the parking lot identified by the parking lot data is not recommended.

[0067] If it is determined that the situation does not involve a variable factor (NO in step S211), in step S213, the parking possibility determination unit 120 determines that parking in the parking lot identified by the parking lot data is recommended.

[0068] After the processes of steps S213 and S215, the registration process ends.

[0069] [Effects of the embodiment] As described in detail above, the information processing device and information processing method of this embodiment accept parking lot data identifying a parking lot and factor data indicating the factors that caused a vehicle to fail to park in the parking lot, and determine whether the factors are variable factors based on the factor data.If it is determined that the factors are not variable factors, it determines that parking in the parking lot is not recommended.

[0070] This allows the parking availability to be determined taking into account various factors that may affect parking, and allows for a more accurate determination of whether parking is possible. In addition, since the parking lot can be set as the destination based on a more accurate determination of whether parking is possible, the possibility of failing to park after the vehicle arrives at the parking lot is reduced, and the parking assistance device can be used effectively.

[0071] In addition, the information processing device and the information processing method according to the present embodiment may determine whether the parking lot is in a situation where the factor is a variable factor, and if it is determined that the factor is in a situation where the factor is in a variable factor, determine that parking in the parking lot is not recommended. This makes it possible to perform a more accurate determination of whether parking is possible for parking lots where the parking possibility changes depending on the parking lot situation.

[0072] As a result, parking spaces where parking is possible are less likely to be determined as impossible, improving parking space utilization efficiency.Furthermore, parking spaces where parking is impossible are less likely to be determined as possible, reducing the possibility of parking failure after the vehicle arrives at the parking space, allowing the parking assistance device to be used effectively.

[0073] Furthermore, the information processing device and the information processing method according to the present embodiment may determine whether or not a factor will occur in a parking lot based on the time or time zone when parking will be performed in the parking lot. This allows for a more accurate determination of whether or not parking is possible based on the parking lot conditions, such as the time or time zone when parking will be performed in the parking lot.

[0074] Furthermore, the information processing device and the information processing method according to the present embodiment may determine whether or not a factor is likely to occur in the parking lot based on the weather in the area in which the parking lot is located. This allows for a more accurate determination of whether or not parking is possible based on the conditions of the parking lot, such as the weather in the area in which the parking lot is located.

[0075] Furthermore, in the information processing device and the information processing method according to the present embodiment, the variation factor may be that the camera mounted on the vehicle cannot capture a part of the surroundings of the vehicle due to backlighting. This makes it possible to determine whether the factor of the parking failure is a variation factor based on the state of the camera mounted on the vehicle, and to more accurately determine whether parking is possible.

[0076] In the information processing device and the information processing method according to the present embodiment, the variable factor may be that the camera mounted on the vehicle cannot capture an image of a part of the surroundings of the vehicle due to bad weather. This makes it possible to determine whether the factor of the parking failure is a variable factor based on the state of the camera mounted on the vehicle, and to more accurately determine whether parking is possible.

[0077] Furthermore, the information processing device and the information processing method according to the present embodiment may determine whether or not a factor is a fixed factor based on the factor data, and if the factor is determined to be a fixed factor, determine that parking in the parking lot is not recommended. This allows the determination of whether parking is possible to be made taking into account various factors that may affect parking, and allows for a more accurate determination of whether parking is possible.

[0078] In the information processing device and the information processing method according to the present embodiment, the fixed factor may be the presence of an object that interferes with the traveling of the vehicle in the parking lot or on the traveling route of the vehicle to the parking lot. This makes it possible to determine whether the factor of the parking failure is a fixed factor or not based on the presence or absence of an object that interferes with the traveling of the vehicle, and to make a more accurate judgment on whether parking is possible.

[0079] Furthermore, in the information processing device and the information processing method according to the present embodiment, the fixed factor may be that the road surface shape of the parking lot or the vehicle's driving route to the parking lot interferes with the vehicle's driving. This makes it possible to determine whether the factor that caused the parking failure is a fixed factor based on whether the road surface shape interferes with the vehicle's driving, and to more accurately determine whether parking is possible.

[0080] Furthermore, the information processing device and information processing method according to the present embodiment may store parking lot data that identifies a parking lot and history data that indicates whether parking at the parking lot was successful in association with each other, and calculate the rate at which parking at the parking lot was successful based on the stored history data. This makes it possible to compare multiple parking lots based on the rate at which parking was successful, and to determine which parking lot is recommended.

[0081] Furthermore, the information processing device and information processing method according to the present embodiment may present parking lots and ratios in association with each other. Furthermore, the information processing device and information processing method according to the present embodiment may present parking lots with higher ratios with higher priority. Furthermore, the information processing device and information processing method according to the present embodiment may present parking lots and ratios in association with each other by a terminal mounted on the vehicle or a user's terminal. This allows a user who receives the information to compare multiple parking lots, and the user can decide which parking lot to park in based on the presented ratios.

[0082] In the information processing device and the information processing method according to the present embodiment, the vehicle may be a vehicle capable of performing automatic parking. This allows the parking possibility to be determined based on the information obtained by the parking assistance device as to whether the automatic parking has been successful or not, while taking into consideration various factors that may affect the automatic parking, and allows for a more accurate determination of whether the parking possibility is possible.

[0083] Furthermore, the information terminal according to the present embodiment may transmit parking lot data to the above-mentioned information processing device and receive a determination result indicating whether parking in the parking lot is recommended or not from the information processing device. This makes it possible to obtain the result of whether parking is possible or not for the parking lot of interest. Furthermore, when the information terminal is a navigation system or a parking assistance device, it is possible to select a parking lot where parking is possible based on a more accurate determination result of whether parking is possible or not, thereby improving the operating efficiency of the entire system.

[0084] In addition, the information terminal according to the present embodiment may notify the user of the determination result via the notification unit, thereby enabling the user to select a parking lot where parking is possible based on a more accurate determination result of whether parking is possible or not.

[0085] Each of the functions described in the above embodiments may be implemented by one or more processing circuits, including a programmed processor, an electrical circuit, or a device such as an application specific integrated circuit (ASIC), or a circuit component arranged to perform the described functions.

[0086] Although the contents of the present invention have been described above in accordance with the embodiments, the present invention is not limited to these descriptions, and various modifications and improvements are possible, which will be obvious to those skilled in the art.
