  However, in the technique of Patent Document 1, since priority is not set for a plurality of applications, an accident occurs when the application execution result is used in a driving context that is presented to a client device mounted on a vehicle. There is a problem that a plurality of applications may not be executed with an appropriate priority, such as music is played instead of an alarm in a dangerous situation with a high possibility.

  Further, in the technique of Patent Document 2, since the use order of the application is determined based on the priority order set in advance by the user, when the application is used in the context of driving, the driver prioritizes the application not related to driving. There is a problem that the priority of an application that may lead to danger may be increased by setting the rank higher.

  Moreover, in the technique of patent document 3, since operation | movement is interrupted when driving load is high, even if it is a service which promotes safe driving | operation, there exists a problem that operation | movement will be restrict | limited.

  Further, in the technique of Patent Document 4, the order of data to be presented to the driver is determined by giving “evaluation value reflecting the necessity for the driver” to the information. It is not described as to how to digitize. In addition, no specific method is described regarding the method of estimating the driving load.

  The present invention has been made to solve the above-mentioned problems, and even if a plurality of applications registered in the platform are individually developed, it is possible to ensure consistency in consideration of safety during driving. It is an object of the present invention to provide a platform device, a program, and a system that can give priorities to individual applications.

  In order to achieve the above object, the platform apparatus of the present invention is used when executing an application, and a plurality of functions each representing a predetermined different function and functions represented by each of the plurality of functions act. The storage means in which the five senses relevance levels corresponding to each other are stored in association with each other, and when there is a registration request for an application using the function, the storage corresponding to the function used by the application having the registration request Based on the five senses relevance stored in the means, the registration means for giving priority to the application for which the registration request has been made and registration, the application registered by the registration means is executed, and the execution result is mounted on the vehicle The output results of multiple applications use the same output device at the same time. Case, the execution result of the higher priority application is configured to include a control means for controlling so as to be outputted from the output device.

  According to the platform device of the present invention, a plurality of functions that are used when executing an application and each represent a different function, and functions expressed by each of the plurality of functions are applied to the storage unit according to the five senses. The five senses relevance levels are stored in association with each other. The five senses relevance can be a value that takes into account the distraction of the five senses. The application developer creates an application using the function stored in the storage means.

  Then, when there is a registration request for the application to the platform device, the registration unit issues a registration request based on the five senses relevance stored in the storage unit in correspondence with the function used by the application for which the registration request has been made. Give priority to the registered application and register. Then, the control means executes the application registered by the registration means, and controls so that the execution result is output by the output device mounted on the vehicle. When using simultaneously, it controls so that the execution result of an application with a high priority may be output from an output device.

  In this way, the function used in the application is stored in association with the five senses relevance corresponding to the five senses on which the function represented by the function acts, and based on the five sense relevance corresponding to the function used by the application. In order to give priority to applications, even if multiple applications registered on the platform are individually developed, each application is given a consistent priority in consideration of safety during driving. Can be granted.

  Further, the function is a function representing a plurality of different functions depending on the urgency level of information presented by execution of an application, and the five sense relevance levels corresponding to the urgency level are associated with the function and stored in the storage unit. can do. Thereby, the execution result of the application can be dynamically changed according to the degree of urgency.

  Moreover, the registration means can further give priority to the application according to the urgency level. Thereby, the priority of an application can be dynamically changed according to the urgency.

  Further, the registration unit can further give a priority to the application based on the relationship between execution of the application and driving of the vehicle. Thereby, the priority which considered the driving action of the driver can be given.

  Also, the platform device of the present invention is used in the priority given to the application and the application based on the execution state of the application when the application is executed and the driving state including the operation of the vehicle. It is possible to include a correcting means for correcting at least one of the five sense relevance levels corresponding to the function.

  In addition, the correction means, for an application or function for instructing operation of the vehicle, when the operation of the corresponding vehicle is performed by execution of the application or the function, For an application or function other than an application that corrects the five senses corresponding to the function to be high and instructs the operation of the vehicle, the driving state indicates dangerous behavior during the execution of the application or the function. In such a case, it is possible to correct the priority given to the application or the five sense relevance corresponding to the function to be low. Thereby, it can correct | amend automatically to the priority according to a more actual driving action.

  In addition, when the control means controls the output result of the application to be output by the output device mounted on the vehicle, the control means limits the output state of the execution result according to the priority or urgency of the application. can do. As a result, in situations where the driver needs attention for driving, the output state of the execution result of the application is limited, thereby ensuring driving safety.

  The platform program of the present invention is a program for causing a computer to function as each means constituting the platform device.

  The storage medium for storing the program of the present invention is not particularly limited, and may be a hard disk or a ROM.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  As shown in FIG. 1, the platform system 1 according to the present embodiment includes a platform device 10 and an in-vehicle client device 60.

  The in-vehicle client device 60 includes a CPU that controls the entire in-vehicle client device 60, a ROM as a storage medium that stores various programs, a RAM that temporarily stores data as a work area, and a computer that includes a bus that connects these. can do.

  The in-vehicle client device 60 includes an operation information acquisition unit 62 configured with an in-vehicle camera, an in-vehicle network (CAN), and the like, and an output device 64 such as a display device and a speaker. The driving information acquisition unit 62 acquires driving information indicating a driving state including operation of the vehicle necessary for executing the application, and transmits the driving information to the platform device 10.

  The platform device 10 includes a CPU that controls the entire platform device 10, a ROM as a storage medium that stores a program of a platform processing routine including a priority scoring process, an application execution process, and a priority correction process, which will be described later, The area can be configured by a computer including a RAM that temporarily stores data and a bus that connects these.

  This computer can be functionally represented by a configuration including an application management unit 20 and an application execution control unit 40, as shown in FIG.

  The application management unit 20 further includes a pre-registration application storage unit 22 that stores an application before registration in the platform, and a function storage that stores functions that are used when executing the applications and that represent different functions. The configuration includes a unit 24, a priority scoring unit 26 that gives priority to an application before registration, and an application registration unit 28 that registers an application to which priority is given on the platform. The priority scoring unit 26 and the application registration unit 28 are examples of the registration unit of the present invention.

  The application execution control unit 40 further includes an operation information storage unit 42 that stores the operation information received from the in-vehicle client device 60, an application execution unit 44 that controls the execution of the application, and the execution result of the application is the in-vehicle client. An output control unit 46 that performs control so as to be output by the output device 64 of the apparatus 60, and a priority correction unit 48 that corrects the priority based on the execution of the application or function and the driving information are used. be able to. The application execution unit 44 and the output control unit 46 are examples of the control unit of the present invention.

  The pre-registration application storage unit 22 stores an application using a function stored in a function storage unit 24 described later. In this embodiment, each application is developed by an individual developer, and when there is a registration request to the platform, the platform provider reviews each application and assigns priority, and registers it to the platform. The form to be assumed is assumed. Therefore, the application for which registration has been requested by each developer is stored in the pre-registration application storage unit 22.

  The function storage unit 24 stores a plurality of functions for realizing functions commonly used in each application. Moreover, the function of the function acts on the human senses of vision, hearing, taste, smell and touch. For example, as shown in FIG. 2, functions for realizing functions such as “sound a sound”, “image display”, “alarm presentation”, and “stream video” can be defined as functions.

  Furthermore, the function represented by each function can be determined in a plurality of stages according to the urgency of the information. For example, the function represented by the function “sound sound” can be used to sound a buzzer or other sound when the level of urgency is high. If the degree is low, it can be set to play music. In this embodiment, the urgency level of information is given as the time until an accident or problem occurs, and the shorter the time until an accident or problem occurs, the higher the urgency level.

  In addition, the five senses on which the functions represented by the function act are defined as the function senses. Even if the five senses are the same, for example, the function that acts on "hearing" is detailed as a function that sounds a simple sound such as an alarm or a function that sounds a complex sound such as music or human voice. To set the five functional senses. In addition, for each of the five functional actions, the five senses relevance used for calculating the priority indicating the priority when executing the application is determined. For example, as shown in FIG. 3, the five senses relevance level for the functional action senses can be determined. The five-sensory relevance level is set to a value that takes into account the distraction to driving based on the relationship between the driving operation and the functional five senses. Specifically, “sight”, which is deeply related to driving operations, is a high degree of distraction (low sense relevance (= priority)), and “hearing”, which is relatively unrelated to driving operations, is under distraction (five senses). “Taste”, “olfactory sense”, and “tactile sense” that are not related to driving operations can be set as low distraction (high sense related degree).

  In addition, for each function represented by each function, an information urgency level corresponding to the urgency level of information used for priority calculation is assigned. As the information urgency level, a value is set such that the higher the urgency level, the higher the priority.

  These functions, the functions they represent, the five functional senses for each function, the five-sensory relevance for each functional action five sense, and the information urgency for each function are determined by the platform provider when the function is newly created. Is stored in the function storage unit 24 as an initial value.

  When there is an application registration request from the application developer, the priority scoring unit 26 assigns an initial priority value to the application for which the registration request has been made. The priority is calculated based on the above five sense relevance, information urgency, and driving relevance described later.

  Specifically, the function used in the application for which the registration request has been made is determined, and the function of the function corresponding to the predetermined initial value of urgency is selected from the functions represented by the function. The five sense relevance level indicated by the functional action senses corresponding to the function to be expressed is acquired. When a plurality of functional action five senses are determined for the function of the selected function, the five sense relevance levels indicated by the respective function action five senses are totaled. For example, if there is a registration request for an application that uses the function “alert presentation”, the function function “human voice and video” is selected when the initial value of the urgency level is ∞ with reference to FIG. Is done. The functional action five senses corresponding to the function “human voice and video” are “hearing (human voice)” and “sight (video)”. With reference to FIG. Auditory (human voice) = 150 ”and“ visual (moving image) = 1 ”are acquired. Then, as shown in FIG. 4, the five-sense relevance level “151” is calculated for the function “alarm presentation” (“human voice and video”).

  In addition, information urgency corresponding to a predetermined initial value of urgency is acquired for a function used in an application for which a registration request has been made. In the case of the above example, the information urgency “1” is acquired with reference to FIG.

  Also, the degree of driving relevance is acquired based on the relationship between the execution of the application for which a registration request has been made and the driving of the vehicle. The degree of driving relevance is determined by the “operation” that instructs the driver to operate the vehicle by executing the application, the “recognition / determination” that affects the driver's recognition and determination by executing the application, Three types of “unrelated” that do not affect any of operation, recognition, and judgment can be defined. For example, as shown in FIG. 5, the degree of driving relevance with respect to the relevance to driving can be determined in advance. As the driving relevance level, a value of “not related” <“recognition / judgment” <“operation” is set in consideration of the relevance with driving. The priority scoring unit 26 determines the relevance to the driving based on the function used in the application for which the registration request has been made and the operation of the application, and refers to FIG. 5 for the relevance to the driving. Get driving relevance.

  Further, the priority scoring unit 26 calculates the priority to be given to the pre-registration application according to the following equation (1) based on the five sense relevance level, the information urgency level, and the driving relevance level acquired as described above. .

      Priority = (Total of five senses relevance + Driving relevance) x Information urgency (1)

  Note that equation (1) is an example of a priority calculation method, and the priority may be calculated based on the sum, product, weighted sum, etc. of the five sense relevance level, the information urgency level, and the driving relevance level.

  The application registration unit 28 registers the application to which the priority is given by the priority scoring unit 26 in the application execution unit 44.

  The application execution unit 44 executes a corresponding application when an application execution request is received from the in-vehicle client device 60. When multiple applications are executed, they are executed by parallel processing. However, when the execution result of the application is output using the same output device 64 of the in-vehicle client device 60 at the same time, the execution result of the application having a high priority assigned to each application is output with priority. To control.

  In addition, when the urgency level of the information changes due to the execution result of each application, the application execution unit 44 uses the information urgency level for the changed urgency level to recalculate the priority according to the equation (1), The execution of each application is controlled based on the priority after recalculation.

  The output control unit 46 performs control so that the execution result of the application by the application execution unit 44 is output by the output device 64 of the in-vehicle client device 60. Further, when the driver needs to pay attention to driving, the output state of the execution result is limited according to the information urgency or priority. Specifically, when the information urgency or priority is high, some of the GUI buttons displayed on the display device cannot be used, or the displayed content or the content output from the speaker is changed. can do. When changing the displayed contents, to reduce the amount of information displayed, display only items with high priority, reduce the number of displayed characters, collect items that represent the same meaning, You can change to an icon display or switch to a screen saver. When changing the output from the speaker, stop the output to the speaker, reduce the volume, if the output content is news, reduce the amount of information, such as headline and summary, to relax BGM Can be changed.

  The priority correction unit 48 accumulates the relationship between the application execution state and the driving information when the application is executed, and the priority given to the application when a certain number of specific driving actions are recorded. Correct the initial value of degree.

  Specifically, when the driving relevance level of an application is “operation”, the higher the probability that the driver actually performed the driving action (operation) instructed by the application, the higher the priority of the application. To increase. This is because the driving behavior of the driver may have changed depending on the driving behavior instructed by the application, leading to safe driving. For example, when an application gives an instruction to the driver to step on the brake and the driver actually steps on the brake, the priority of the application is increased. More specifically, the priority is raised when the probability that the application instructs the driving action and actually applies the brake exceeds a threshold (for example, 0.8), and the probability that the application actually applies the brake is less than the threshold. In case of, the priority can be lowered. In addition, every time there are five instances where the brake is actually depressed according to an instruction from the application, the priority can be corrected by an operation that adds +10 to the initial priority value of the application.

  In addition, when the driver actually steps on the brake, an application with multiple driving relevance levels of “Operation” is executed, and if both applications present the same driving operation, the operation is indicated. The earlier the time, the higher the priority of the application. For example, when “application A” and “application B” are operating, and “application A” instructs the driver to perform the same operation X after “application B” instructs the driver, the driver When the operation X is actually performed, the priority of “application A” is made higher than “application B”.

  On the other hand, if the driving relevance level of an application is “recognition / judgment” or “not related”, there is a risk that the driver will step on the brake or turn the steering wheel suddenly when using the application. The lower the priority, the lower the priority. This is because the operation of the application is a driving distraction for the driver, and it is considered that the driving behavior of the driver has changed. For example, when the probability that the driver stepped on the brake suddenly exceeds a threshold value (for example, 0.2) while executing an application for watching a movie, the priority is lowered, or there are two cases where the driver actually stepped on the brake suddenly. The priority is corrected by an operation such as -10.

  The priority correction unit 48 accumulates the relationship between the execution state of the function used at the time of executing the application and the driving information, and uses the function when a certain number of specific driving actions are recorded. The five senses relevance used to calculate the priority assigned to the application is corrected.

  Specifically, when the driving relevance of the original application using a function is “driving operation”, the higher the probability that the driver actually performed the driving action indicated by the function, Increase the five-sensory relevance used to calculate the priority assigned to the application that uses the function. This is because the driving behavior of the driver may change depending on the driving behavior indicated by the function, leading to safe driving. For example, in the application A in which the function of “alarm presentation” is used, when alarm presentation is executed, if the driver actually steps on the brake, the degree of relevance to the five senses is increased. More specifically, when the probability that the function instructs driving action and steps on the brake exceeds a threshold (for example, 0.8), the degree of relevance to the five senses is raised, and conversely, the probability that the brake is actually pressed is less than the threshold. In the case of, the five senses relevance is corrected by an operation that lowers the senses relevance or increments the five senses relevance every time there are five instances of stepping on the brake.

  Conversely, when the driving relevance of the original application that uses a certain function is “recognition / judgment” or “not related to driving”, when the function is used, The more dangerous driving occurs, such as turning the steering wheel, the lower the sense-related level is. This is because the operation of the function is a driving distraction for the driver, and the driving behavior of the driver is considered to have changed. For example, if the probability that the driver stepped on the brake suddenly exceeds a threshold value (for example, 0.2) while operating the function of “flowing video” in a movie watching application, Every time there are two cases of sudden braking, the calculation is performed such that the relevance level of the fifth sense is -10, and the relevance level of the fifth sense is corrected.

  In addition, the priority calculated using the five sense relevance is corrected by correcting the five sense relevance. Further, the correction of the priority and the five senses relevance may be performed using driving information of a plurality of drivers, or may be performed using driving information of individual drivers.

  Next, the operation of the platform system 1 according to the present embodiment will be described. Here, in the state where the “white line recognition application” and the “earthquake warning application” are already registered in the platform device 10, a “preceding vehicle approach warning application” is newly registered, and three applications are executed on the platform device 10. A case where control is performed as described above will be described as an example.

  First, when there is a registration request for the “preceding vehicle approach warning application” from the application developer, the priority scoring process shown in FIG.

  First, in step 100, the pre-registration application “preceding vehicle approach warning application” requested for registration is stored in the pre-registration application storage unit 22. Next, in step 102, a function used for the pre-registration application “preceding vehicle approach warning application” is determined. Here, it is assumed that the function “warning presentation” is used for the “preceding vehicle approach warning application”.

  Next, in step 104, referring to the correspondence between the function stored in the function storage unit 24 and the five sense relevance levels (for example, FIG. 2 and FIG. 3), the initial value of the urgency level is set to ∞, The functional sense five senses “auditory (human voice)” and “visual (video)” corresponding to the function “human voice and video” of “” are the five sense related degrees “auditory (human voice) = 150” and “visual ( Movie) = 1 ”. Then, the five senses relevance levels are summed, and an initial value of the five sense relevance levels of “151” is set.

  Next, in step 106, the function “alarm presentation” determined in step 102 is referred to the correspondence between the function stored in the function storage unit 24 and the information urgency level (for example, FIG. 2). Is set to ∞, information urgency is acquired, and an initial value of information urgency of “1” is set.

  Next, in step 108, the relevance with the driving of the application is determined based on the function used in the pre-registration application “preceding vehicle approach warning application” and the operation of the application. For example, it is possible to create a table in advance that associates the operation of a function or application being used with the relevance of driving, and refers to this table to determine the relevance with driving. If the "preceding vehicle approach warning application" is an application that detects the approach of the preceding vehicle, sounds an alarm, and instructs the driver to step on the brake, the relevance to the driving of the "preceding vehicle approach warning application" is , “Operation” is determined. Then, referring to the correspondence between the relevance with the predetermined driving and the driving relevance (for example, FIG. 5), the driving relevance for the relevance “operation” with the driving is acquired, and the driving relevance “1000” is obtained. Set the initial value of degrees.

  Next, in step 110, the initial value “151” of the five senses relevance set in step 104, the initial value of information urgency “1” set in step 106, and the initial driving relevance set in step 108 Based on the value “1000”, an initial value of priority is calculated according to the equation (1). Here, the initial value of the priority = (151 + 1000) × 1 = 11151. Then, the initial value of the calculated priority is assigned to the “preceding vehicle approach warning application”, and the process ends.

  It should be noted that the already registered “white line recognition application” and “earthquake warning application” are also given initial priority values by the same process as described above at the time of registration. Specifically, for the “white line recognition application”, when the function used is “image display” and the driving relevance is “recognition / judgment”, the initial value of the five sense relevance of the “white line recognition application” is 310. The initial value of information urgency is 1, the initial value of driving relevance is 300, and an initial value 610 of priority is given. For the “earthquake alarm application”, when the function used is “alarm presentation” and the driving relevance level is “unrelated”, the initial value of the five senses relevance level of the “earthquake alarm application” is 151, the information urgency level The initial value of 1 is 1, the initial value of driving relevance is 0, and an initial value 151 of priority is given.

  Next, execution of three applications will be described. When an application execution request is received from the in-vehicle client device 60 side, the platform device 10 executes an application execution process shown in FIG.

  First, in step 200, the driving information transmitted from the in-vehicle client device 60 is acquired and stored in the driving information storage unit 42.

  Next, in step 202, each application requested to be executed is executed. Here, the preceding vehicle approach warning application process shown in FIG. 8A, the white line recognition application process shown in FIG. 8B, and the earthquake warning application process shown in FIG. 8C are executed in parallel.

  In the preceding vehicle approach warning application process, in step 2020a, the preceding vehicle is recognized based on the captured image obtained by capturing the periphery of the vehicle included in the driving information, and the distance to the preceding vehicle is calculated. As the preceding vehicle recognition method, a conventionally known method can be used, and thus detailed description thereof is omitted. Next, in step 2022a, a time t until the vehicle collides with the preceding vehicle is calculated based on the speed of the host vehicle included in the driving information and the distance to the preceding vehicle calculated in step 2020a. When the time t is equal to or longer than the predetermined time, ∞ is set, and this time t is the information urgency. Next, in step 2024a, the function (F) “alarm presentation” stored in the function storage unit 24 is called. Then, based on the function “alarm presentation” when the information urgency level (time t) is given as an argument of the function, the execution result (presentation sound, presentation image) of the application is output and the process returns.

  In the white line recognition application process, in step 2020b, a white line is recognized based on the captured image included in the driving information. As the white line recognition method, a conventionally known method can be used, and thus detailed description thereof is omitted. In the white line recognition process, since the time until an accident or problem occurs is not calculated, the urgency of the information is set to ∞. Next, in step 2024b, the function (F) “image display” stored in the function storage unit 24 is called. Based on the function “image display” function (“still image”) when information urgency (∞) is given as the function argument, the application execution result (presentation position, presentation image) is output. And return.

  In the earthquake warning application process, in step 2020c, the time T until the earthquake occurs is recognized based on the vehicle position included in the driving information and the earthquake information. If the time T is equal to or longer than the predetermined time, ∞ is set, and this time T is the urgency of the information. Next, in step 2024 c, the function (F) “alarm presentation” stored in the function storage unit 24 is called. Then, based on the function “alarm presentation” when the information urgency (time T) is given as an argument of the function, the execution result (presentation sound, presentation image) of the application is output, and the process returns.

  Next, the process proceeds to step 204, where it is determined whether or not the urgency level of the information obtained in the process of step 202 has changed since the previous process. If the urgency has changed, the process proceeds to step 206, and if not, the process proceeds to step 208. Here, it is assumed that the urgency level (time T) of the information obtained by the earthquake warning application processing has changed from ∞ at the time of the previous processing to “15 seconds”, and the information obtained by the preceding vehicle approach warning application and the white line recognition application Assume that the urgency has not changed.

  In that case, the process proceeds to step 206 to recalculate the priority of each application. As for the preceding vehicle approach warning application and the white line recognition application, since the urgency of the information has not changed, the priority does not change. For the earthquake warning application, referring to FIG. 2, the five-sense relevance level is 160, the information urgency level is 10, the driving relevance level is 0 without change, and the priority = (160 + 0) × 10 = 1600 is recalculated. . Therefore, the priority of the earthquake warning application is the highest among the preceding vehicle approach warning application, the white line recognition application, and the earthquake warning application. Until the pre-processing, as shown in FIG. 9A, when the execution result of the preceding vehicle approach warning application having the highest priority is displayed on the display device, if the priority changes as described above, As shown in the figure (b), the earthquake warning is displayed on the display device from the display of the recognition result of the preceding vehicle. In addition, presentation by sound from the speaker also prioritizes presentation of the execution result of the earthquake warning application, for example, presenting an alarm such as “An earthquake occurred after 15 seconds. Please park your car immediately on the shoulder.” Can do.

  Next, in step 208, it is determined whether or not to execute an output control process for limiting the output state according to the information urgency level or priority level, depending on whether or not the driver is in a situation that requires attention. For example, based on the driving information, when the vehicle speed is equal to or higher than a predetermined value, or when traveling in an urban area, it can be determined that the driver is in a situation that requires attention. If the output control process is to be executed, the process proceeds to step 210; otherwise, the process proceeds to step 212.

  In step 210, the output control process shown in FIG. 10 is executed.

First, in step 2100, it determines granted priority in the application that output the execution result whether or not a predetermined threshold value th ₁ smaller. If the priority <th _1, the process proceeds to step 2102, and stops output of the execution result speaker. If priority ≧ th _1, the process proceeds to step 2104.

In step 2104, the priority is determined whether or not a predetermined threshold value th ₂ smaller. The threshold th ₂ is a value larger than the threshold th ₁ . If priority <th _2, the process proceeds to step 2106, it lowers the volume when outputting the execution result from the speaker. If priority ≧ th _2, the process proceeds to step 2108.

In step 2108, the priority is determined whether or not a predetermined threshold value th ₃ smaller. The threshold th ₃ is larger than the threshold th ₂ . If the priority <th _3, the process proceeds to step 2110, it determines whether the contents of the content to be outputted by the execution result voice. In the case of voice content, the process proceeds to step 2112 and the presentation sound (voice) output from the speaker is changed to a relaxing BGM. If the priority is greater than or equal to th ₂ , or if the content is not a voice content, the process proceeds to step 2114.

In step 2114, the priority is determined whether or not a predetermined threshold value th ₄ smaller. The threshold th ₄ is larger than the threshold th ₃ . If priority <th _4, the process proceeds to step 2116 to determine whether or not the content to be output is news based on the execution result. In the case of news, the process proceeds to step 2118, and the content of the news to be output is changed to only the headline or summary. If priority ≧ th _4, or if not the news, then proceeds to step 2120, and directly outputs the execution result by the application.

  Next, a priority correction processing (priority) routine executed in the platform device 10 will be described with reference to FIG. This routine is executed in parallel with the application execution processing routine.

  In step 300, the execution state of the application when the application is executed and driving information are stored in association with each other. Next, in step 302, based on the accumulated driving information, it is determined whether or not a predetermined number or more of predetermined driving actions such as sudden braking are accumulated. If a predetermined number or more of predetermined driving behaviors are accumulated, the process proceeds to step 304. If the predetermined number is not reached, the process returns to step 300 to continue accumulation of driving information and application execution state.

  In step 304, it is determined whether or not the driving relevance determined in step 106 of the priority scoring process (FIG. 6) is “operation” for the application to be processed. If the driving relevance is an operation, the process proceeds to step 306, and the probability that the driver actually performed the operation instructed by the application is calculated. Then, the process proceeds to step 310, and when the probability calculated in step 306 exceeds a predetermined threshold (for example, 0.8), correction is performed so as to increase the priority assigned to the application. Conversely, if the probability calculated in step 306 is equal to or less than a predetermined threshold value, the priority given to the application is corrected to be lowered.

  On the other hand, if it is determined in step 304 that the driving relevance level of the application to be processed is not an operation, that is, the driving relevance level is “recognition / judgment” or “not related”, the process proceeds to step 308. . In step 308, the probability that the driver took a dangerous action such as stepping on a sudden brake while the application is being executed is calculated. Then, the process proceeds to step 310, and when the probability calculated in step 308 exceeds a predetermined threshold value (for example, 0.2), the priority given to the application is corrected to be lowered. The process is terminated.

  Next, with reference to FIG. 12, a priority correction processing (five sense relevance) routine executed in the platform device 10 will be described. This routine is executed in parallel with the application execution processing routine.

  In step 320, the execution state of the function used when executing the application and the driving information are stored in association with each other. Next, in step 322, based on the accumulated driving information, for example, it is determined whether or not a predetermined number or more of predetermined driving actions such as sudden braking are accumulated. If a predetermined number or more of the predetermined driving behaviors are accumulated, the process proceeds to step 324, and if the predetermined number is not reached, the process returns to step 320 to continue accumulation of the driving information and the function execution state.

  In step 324, it is determined whether or not the driving relevance determined in step 106 of the priority scoring process (FIG. 6) is “operation” for the original application using the function to be processed. If the driving relevance is an operation, the process proceeds to step 326, and the probability that the driver actually performed the operation indicated by the function is calculated. Then, the process proceeds to step 330, and when the probability calculated in the above step 326 exceeds a predetermined threshold (for example, 0.8), the priority given to the original application using the function is calculated. The five senses relevance (the five sense relevance set in step 104 of the priority scoring process (FIG. 6)) used for the correction is corrected. Conversely, if the probability calculated in step 326 is less than or equal to a predetermined threshold, correction is made so that the degree of relevance to the five senses is lowered.

  On the other hand, if it is determined in step 324 that the driving relevance of the original application using the function to be processed is not an operation, that is, the driving relevance is “recognition / judgment” or “not related”. The process proceeds to step 328. In step 328, the probability that the driver took a dangerous action such as stepping on the brake suddenly during the execution of the function is calculated. Then, the process proceeds to step 330, and when the probability calculated in the above step 328 exceeds a predetermined threshold (for example, 0.2), the priority given to the original application using the function is calculated. The correction is made so as to reduce the degree of relevance of the five senses used at the time, and the process is terminated.

  As described above, according to the platform system of the present embodiment, the senses related to the senses driving are considered in accordance with the senses that the function represented by the function acts on the function used in the application. The degrees are stored in association with each other. When giving priority to each application, even if multiple applications registered on the platform are individually developed by using the five-sense relevance level corresponding to the function used in each application. In consideration of safety during operation, consistent priority can be given to each application.

  Further, when the priority is calculated, the information urgency is used, so that the priority can be dynamically changed when the urgency is changed by executing the application.

  Further, when calculating the priority, the priority in consideration of the driving behavior of the driver can be calculated by using the driving relevance corresponding to the relevance with the driving of the application.

  Further, since the priority or the five senses relevance is corrected based on the relationship between the execution state of the application or function and the driving behavior, it is possible to correct the priority according to the actual driving behavior.

  In the above-described embodiment, the case where the output state of the execution result is limited by the output control process has been described. However, the access from the in-vehicle client device side to the platform device side may be prohibited.

  In the above embodiment, the case where three types of “operation”, “recognition / judgment”, and “operation” are used as the relationship with the driving of the application has been described. Alternatively, four or more types classified in more detail according to the degree of association may be used.
