Description

  The present disclosure relates to a vehicle inquiry system that acquires a user's feeling and vehicle data in association with each other.

  The vehicle data relating to the behavior of the running vehicle and the user's feeling about the behavior of the vehicle are important information that can be used for vehicle diagnosis and vehicle development. Therefore, a technique has been proposed in which a large amount of vehicle data is acquired while the vehicle is traveling, and the acquired data is analyzed and used. However, it is difficult to obtain the user's feeling about the behavior of the vehicle unless an inquiry by the mechanic is performed when entering the dealer.

  Therefore, the vehicle inquiry system described in Patent Document 1 detects the timing at which the user feels uncomfortable with the behavior of the vehicle based on the user's behavior, and associates the vehicle data before and after the detected timing with the user's uncomfortable feeling. To get and record.

Hereinafter, embodiments for carrying out the invention will be described with reference to the drawings.
<Configuration>
First, a configuration of a vehicle inquiry system 100 according to the present embodiment (hereinafter referred to as an inquiry system 100) will be described with reference to FIG. The inquiry system 100 includes a server 50, a developer terminal 70, a vehicle device 30, an inquiry module 34, a wireless communication device 35, and an HMI device 36. The inquiry system 100 is a system that, when an abnormality appears in the vehicle data, asks the user and obtains the vehicle data and the user's touch in association with each other. The user here assumes a driver or a passenger.

  The server 50 is mainly composed of a known microcomputer having a CPU, ROM, RAM, semiconductor memory, I / O, and the like, and is installed in an information center or the like. The server 50 includes an inquiry trigger management DB 51 and a customer vehicle management DB 52. DB is an abbreviation for database.

  The inquiry trigger management DB 51 is a storage device, and stores an inquiry management table as shown in FIG. In the inquiry management table, for each inquiry trigger, a priority, a collection condition, an inquiry scenario, collected data, a re-examination possible time, and a grant point are associated with each other. The priority is a priority at which the corresponding inquiry trigger is executed. The higher the value, the higher the priority, and the higher the important inquiry related to the traveling of the vehicle. The collection condition is a condition for collecting vehicle data and inquiry data. When the vehicle data satisfies the collection condition, the inquiry data and vehicle data are acquired. The vehicle data is data related to the behavior of the vehicle, and includes data indicating the driving environment, data indicating the operating state of the engine, driving time, and the like. The inquiry data is a user's answer to the inquiry. The collection condition is a condition for determining that an unusual sign appears in the vehicle data. That is, the inquiry data and the vehicle data are acquired when an unusual sign appears in the behavior of the vehicle.

  The inquiry scenario is the contents of an inquiry for the user when the vehicle data satisfies the collection conditions, and is related to the collection conditions. In other words, the inquiry scenario is a content for asking questions about the user's feelings regarding signs that are different from normal that appear in the vehicle data. The collected data is a data set to be collected when the vehicle data satisfies the collection condition, and is a set of vehicle data related to the collection condition. That is, the data set is vehicle data in which signs different from usual appear and vehicle data related to the vehicle data.

  The re-interrogation possible time is the time until the next inquiry of the same inquiry trigger can be executed after executing the inquiry of the predetermined inquiry trigger. If the same inquiry is repeated at a short time interval, the user may be uncomfortable. Therefore, the re-interrogation possible time is set so as not to repeat the same inquiry at a short time interval. Since the necessary collection frequency differs depending on the data set to be collected, the re-interrogation possible time is set according to the data set to be collected. Further, the grant point is a privilege given to the user who answered the inquiry, and the higher the acquisition request at that time, the higher the value. For example, the reward points can be exchanged for prizes or the like when a predetermined point or more is accumulated.

  The customer vehicle management DB 52 is a storage device, and records the vehicle data and inquiry data acquired when the vehicle data satisfies the collection conditions. In the customer vehicle management DB 52, vehicle data and inquiry data collected from a plurality of vehicles are recorded in association with each other. In that case, you may make it record in a customer vehicle management DB52 in association with vehicle data and inquiry data for every vehicle model.

  A dealer terminal 60 and a developer terminal 70 are wirelessly connected to the server 50. The dealer terminal 60 is a terminal handled by a mechanic in charge of repairing a vehicle at the dealer. The mechanic can access the customer vehicle management DB 52 from the dealer terminal 60 and refer to vehicle data and inquiry data regarding the vehicle to be repaired. The developer terminal 70 is a developer terminal handled by a vehicle developer. The developer can access the inquiry trigger management DB 51 from the developer terminal 70 and rewrite the contents of the inquiry trigger management DB 51, for example, the collection conditions and the inquiry scenario according to the needs of the market. Further, the developer terminal 70 can access the customer vehicle management DB 52 and refer to vehicle data and inquiry data collected from a plurality of vehicles, and can use them for vehicle diagnosis and development.

  The vehicle device 30 is mainly configured by a known microcomputer including a CPU, a ROM, a RAM, a semiconductor memory, an I / O, and the like, and includes a vehicle DB 33. The vehicle device 30 realizes the functions of the monitoring unit 31 and the recording control unit 32 by the CPU executing a program stored in a non-transitional physical recording medium. Furthermore, by executing this program, a method corresponding to the program is executed. Note that the number of microcomputers constituting the vehicle device 30 may be one or more. An inquiry module 34, a wireless communication device 35, an HMI device 36, and various ECUs 8 are connected to the vehicle device 30.

  The monitoring unit 31 receives vehicle data from various ECUs 8 via the vehicle LAN 9. The various ECUs 8 are an engine ECU that controls the engine, an air conditioner ECU that controls the air conditioner, a meter ECU that controls the meter, and the like. The various ECUs 8 are respectively connected to various sensors 10 and various drive units 11, and vehicle data including detection values detected by the various sensors 10, drive signals of the various drive units 11, and the like are transmitted via the vehicle LAN 9. Transmit to the monitoring unit 31. The monitoring unit 31 is connected to an HMI device 36 to be described later, and receives the user status from the HMI device 36. The user status is data relating to the user status such as whether the user is talking or listening to music / radio. The monitoring unit 31 monitors the vehicle data and the user situation, and determines the timing for performing an inquiry.

  The recording control unit 32 controls data recording in the vehicle DB 33 and the customer vehicle management DB 52. Specifically, the recording control unit 32 receives the vehicle data transmitted from the various ECUs 8 and periodically records the vehicle data that is regularly received in the vehicle DB 33 with a time stamp. The vehicle DB 33 is a storage device. Further, the recording control unit 32 records the vehicle data acquired when the collection condition is satisfied in the customer vehicle management DB 52 via the wireless communication device 35.

  The inquiry module 34 is a module that controls dialogue with the user via the microphone 36 b and the speaker 36 c of the HMI device 36. The inquiry module 34 collects user answers to the inquiry and records the collected user answers in the customer vehicle management DB 52 via the wireless communication device 35. In the present embodiment, the inquiry module 34 corresponds to an inquiry unit.

  The wireless communication device 35 is a device having a function of performing wireless communication with the server 50 via a wide area wireless communication network. An inquiry management table is transmitted from the inquiry trigger management DB 51 to the monitoring unit 31 via the wireless communication device 35 and vehicle data and inquiry data are transmitted from the recording control unit 32 to the customer vehicle management DB 52.

  The HMI device 36 is an interface with a user on board, which includes an operation device 36a, a microphone 36b, a speaker 36c, and a camera 36d. HMI is an abbreviation for Human Machine Interface. The operation device 36a is various buttons, various levers, a touch panel, etc. operated by the user. The operation device 36 a includes a button for setting rejection of automatic inquiry by the vehicle device 30. When the user wants to reject the automatic inquiry, the user may set the rejection of the automatic inquiry by operating the operation device 36a in advance. The microphone 36b is a device that inputs sound and sound in the vehicle interior, and is installed at a position where it is easy to collect sound emitted by the user. The speaker 36c is a device that outputs sound and sound into the vehicle interior. The camera 36d includes a CCD sensor, a CMOS sensor, and the like, and is a device that captures an image of a user in the vehicle interior.

  Similar to the vehicle diagnosis system disclosed in Japanese Patent Application Laid-Open No. 2014-201085, the vehicle device 30 may include a function of an abnormal input determination unit, and the server 50 may include a function of a diagnosis unit and a diagnosis DB. The HMI device 36 may be configured to transmit an abnormal input signal to the abnormal input determination unit when it is determined that the user's behavior matches an abnormal behavior registered in advance.

  In this case, when an abnormal input signal is input from the HMI device 36, the abnormal input determination unit determines that an abnormal input based on the user's behavior has occurred, and sends the abnormality detection signal to the recording control unit 32 and the inquiry module 34. Send. Further, when the recording control unit 32 receives the abnormality detection signal, the recording control unit 32 reads out the vehicle data from the time point received from the time point received to the time point received from the vehicle DB 33, and the read vehicle data is transmitted via the wireless communication device 35. To the customer vehicle management DB. Further, the diagnosis unit of the server 50 diagnoses the vehicle data in the customer vehicle management DB using the diagnosis scenario of the diagnosis DB.

<Interview processing>
Next, a processing procedure for interrogating the user will be described with reference to the flowchart of FIG.

  First, in S10, the monitoring unit 31 receives an inquiry management table from the inquiry trigger management DB 51 via the wireless communication device 35, and monitors whether the vehicle data satisfies any collection condition of the inquiry management table. And when vehicle data satisfy | fills any collection conditions, it progresses to S20. Here, the inquiry trigger in which the vehicle data satisfies the collection condition is referred to as a target trigger.

  In S20, the monitoring unit 31 determines whether or not the retrievable time of the target trigger has elapsed since the completion of the previous target trigger inquiry. Specifically, it is determined whether or not the time counter reset when the previous inquiry of the target trigger is completed exceeds the re-interrogation possible time of the target trigger. If the re-interrogation available time has not elapsed, the process returns to S10.

  On the other hand, if the re-interrogation available time has elapsed, the process proceeds to S30. In S <b> 30, the monitoring unit 31 checks whether the user situation is a situation where an inquiry is possible. In situations where the driving load of the vehicle is high and the user has to concentrate on driving, it should not be questioned for safety. Also, in situations where the user is enjoying conversation or the like and is likely to make the user uncomfortable by interrogating the user, it is better to refrain from low-priority interrogation. Therefore, the user situation is checked. Details of the user status check will be described later.

  Subsequently, in S40, the monitoring unit 31 determines whether or not an inquiry is possible from the situation of the user determined in S30. If an inquiry is possible, the monitoring unit 31 instructs the inquiry module 34 to make an inquiry, and the process proceeds to S50.

  In S <b> 50, the inquiry module 34 makes an inquiry to the user in accordance with the inquiry scenario of the target trigger received from the monitoring unit 31. Specifically, the inquiry module 34 outputs an inquiry scenario to the HMI device 36, and outputs the inquiry scenario from the speaker 36c by voice. The interview scenario is, for example, a content such as “Is the engine blown up bad?” If the collection conditions are conditions related to the engine, and “Odor” if the collection conditions are conditions related to the air conditioner. , Would you make an unusual noise? "

  Subsequently, in S60, the recording control unit 32 receives the user's answer to the target trigger inquiry input to the HMI device 36 from the HMI device 36 and corresponds to the target trigger data set from the monitoring unit 31. Receive vehicle data. Then, the recording control unit 32 records the received user response and vehicle data in the customer vehicle management DB 52 via the wireless communication device 35.

  Subsequently, in S70, the monitoring unit 31 resets the time counter of the target trigger for which the inquiry has been completed. As a result, the time counter of the target trigger restarts counting from zero. Thereafter, the process returns to S10.

  On the other hand, if it is determined in S40 that the inquiry is impossible, the process proceeds to S80. In S <b> 80, the recording control unit 32 receives vehicle data corresponding to the target trigger data set from the monitoring unit 31. The recording control unit 32 records only the vehicle data in the vehicle DB 33 and also records it in the customer vehicle management DB 52 via the wireless communication device 35. The collection amount and collection time of vehicle data are defined for each inquiry trigger.

Subsequently, in S90, the process waits for a waiting time W and returns to S10. The waiting time W is a value set in S30 described later, and a different value is set according to the user situation.
<User status check processing>
Next, a processing procedure for checking a user's situation will be described with reference to a flowchart of FIG. This processing procedure is executed by the monitoring unit 31.

  First, in S300, the inquiry difficulty level D is set to zero. The question difficulty D is an index indicating the difficulty of questioning the user, and a higher value is set as the user situation is more likely to make the user uncomfortable when the user is interviewed. For example, if the priority is set in four stages according to the priority level, the inquiry difficulty level D may be set in four stages.

  Subsequently, in S310, based on the user situation received via the HMI device 36, it is determined whether or not automatic inquiry is permitted. If automatic inquiry is not permitted, the process proceeds to S320. In S320, it is determined that the user situation is an inquisition impossible situation, and the process proceeds to S40.

  On the other hand, if automatic inquiry is permitted in S310, the process proceeds to S330. In S330, based on the user situation received via the HMI device 36, it is determined whether music or radio is playing in the passenger compartment. If music or radio is on, the process proceeds to S340, and if music or radio is not on, the process proceeds to S350.

In S340, the inquiry difficulty level D is set to 1, and the process proceeds to S350.
In S350, it is determined whether there is an occupant other than the driver based on the received user situation. If there is no occupant other than the driver in S350, the process proceeds to S380. On the other hand, if there is an occupant other than the driver in S350, the process proceeds to S360.

  In S360, based on the received user situation, it is determined whether the driver and another occupant are in conversation. If it is not in conversation in S360, the process proceeds to S380. In S360, if a conversation is in progress, the process proceeds to S370. In S370, the monitoring unit 31 sets the inquiry difficulty level D to 2, and the process proceeds to S380. In general, drivers are less likely to be disturbed during conversations with other passengers than when listening to music or radio, so they are listening to music or radio during conversations with other passengers. The inquiry difficulty level D is set higher than the case.

  In S380, based on the received vehicle data, it is determined whether the user situation is a situation where an emergency driving operation such as a sudden brake or a sudden steering wheel is being executed, or a situation immediately after the emergency driving operation is executed. That is, it is determined whether or not the user situation requires special attention to the driving operation and the user's attention should not be warped by an inquiry. In S380, if the user situation is a situation where an emergency driving operation is being performed or a situation immediately after that, the process proceeds to S320, and the process of S320 is performed.

  On the other hand, in S380, if the user situation is neither an emergency driving operation situation nor a situation immediately after that, the process proceeds to S390. In S390, it is determined whether or not there is a target trigger having a higher priority than the set question difficulty D in the target trigger. In S390, if there is no target trigger that has a higher priority than the inquiry difficulty level D, when the user is asked, only the less important question is given to the user who does not want to be disturbed, making the user uncomfortable. I will let you. Therefore, in this case, it is determined that the situation makes the user uncomfortable when the inquiry is performed, and the process proceeds to S320, and the process of S320 is executed.

  On the other hand, in S390, when there is a target trigger having a higher priority than the inquiry difficulty level D, the process proceeds to S400. At this time, not only the target trigger whose priority is higher than the question difficulty D, but also the target trigger whose priority is the question difficulty D or less is directly set as the question target. This is because it is expected that the user will not feel much burden even if a relatively low priority subject trigger inquiry is performed together when performing a relatively high priority subject trigger inquiry. However, when conducting an inquiry, taking into account the case where the user gets tired on the way and stops answering, the interview is performed in order from the highest priority. In S400, the inquiry module 34 is instructed to obtain user approval. Details of the user approval process will be described later.

<User approval process>
Next, a processing procedure for obtaining user approval will be described with reference to the flowchart of FIG. The inquiry module 34 executes this processing procedure.

  First, in S410, the user is asked whether or not an inquiry can be performed via the HMI device 36. That is, a question “Is it OK to make an inquiry now?” Is output to the HMI device 36, and the question is output from the speaker 36c by voice. At this time, along with the above question, it is presented to the user that a privilege is given to the answer to the interview. For example, together with the above question, the content “X points can be obtained if you answer” is output to the HMI device 36 and output from the speaker 36 c by voice.

  Subsequently, in S420, it is determined whether or not the user's answer input via the HMI device 36 is positive with respect to the question in S410. If the user's answer is affirmative in S420, it is determined in S430 that the user situation is an interrogation-possible situation, and the process proceeds to S40.

  On the other hand, if the user's answer is negative in S420, the degree of rejection of the user is determined in the following S440 to S490, and the higher the degree of rejection so that an answer can be obtained in the next interview, The waiting time W until the next inquiry is set longer.

  First, in S420, when a user's answer is negative, it progresses to S440. In S440, the wavelength or strength of the user's voice input via the HMI device 36 is analyzed to determine whether or not the user's voice is grumpy.

  In S440, if the user's voice is not displeased, the process proceeds to S450, and the waiting time W is set to 10 minutes, which is the shortest among those rejected by the user. Thereafter, the process proceeds to S460, where it is determined that the user situation is an inquisition impossible situation, and the process proceeds to S40.

  On the other hand, in S440, when a user's voice is unpleasant, it progresses to S470 and a user's voice is analyzed and it is determined whether it contains anger. If the user's voice does not include anger in S470, the process proceeds to S480, and the waiting time W is set to an intermediate one hour while being rejected by the user. Thereafter, the process of S460 is executed.

  On the other hand, if the user's voice includes anger in S470, the process proceeds to S490, and the waiting time W is set to the longest day among the rejections by the user. Thereafter, the process of S460 is executed.

<System operation>
Next, the operation of the inquiry system 100 will be described with reference to the sequence diagrams of FIGS.

  First, in A1, the developer records the inquiry management table including the collection conditions and the inquiry scenario shown in FIG. 3 in the inquiry trigger management DB 51 of the server 50 from the developer terminal 70. Subsequently, in A <b> 2, the server 50 transmits an inquiry management table to the monitoring unit 31 via the wireless communication device 35. Subsequently, in A3, the monitoring unit 31 starts monitoring the vehicle data received from the ECU 8 whether or not the collection condition is satisfied. In A3 and A4, the vehicle data and the collection conditions do not match for any inquiry trigger, and in A5, the vehicle data and the collection conditions match for inquiry triggers 1, 2, and 4. That is, the inquiry triggers 1, 2, and 4 are subject triggers. Subsequently, in A6, the monitoring unit 31 starts monitoring the user status received from the HMI device 36 to determine whether the question difficulty D for the user is less than the priority of the question triggers 1, 2, and 4. In A6, the inquiry difficulty level D is equal to or higher than the priority of the inquiry triggers 1, 2, and 4. In A7, the vehicle data and the collection conditions for the inquiry triggers 1, 2, and 4 continue to match. In A8, the inquiry difficulty level D is less than the priority of the inquiry triggers 1 and 4, and the inquiry condition is cleared.

  Therefore, in A9, the monitoring unit 31 notifies the inquiry module 34 that the inquiry condition has been cleared, and transmits the inquiry scenarios A, B, and D of the inquiry triggers 1, 2, and 4. At this time, regarding the interview trigger 2, the interview difficulty level D is not less than the priority, but since the interview trigger 2 is also interviewed together with the interview triggers 1 and 4, the interview scenario B is combined with the interview scenarios A and D. Also send.

  Subsequently, in A10, the inquiry module 34 receives the notification of clearing the inquiry condition and asks the user whether or not the inquiry can be performed now. Subsequently, in A11, the inquiry module 34 obtains an OK answer from the user. In A12, the inquiry module 34 notifies the monitoring unit 31 that the inquiry is started in response to obtaining an OK answer from the user.

  In A13 to A19, the inquiry module 34 sequentially inquires in the order of high-priority inquiry scenarios A → D → B and obtains an answer from the user. Finally, the inquiry module 34 notifies the user of thanks for cooperating with the inquiry. In A20 to A26, in parallel with A13 to A19, data sets a, d, b of the inquiry triggers 1, 4, 2 are collected. First, the monitoring unit 31 instructs the recording control unit 32 to record the data sets a, d, and b. In response to an instruction from the monitoring unit 31, the recording control unit 32 records the vehicle data of the data sets a, d, and b transmitted from the various ECUs 8 in the customer vehicle management DB.

  Subsequently, in A27, the inquiry module 34 notifies the monitoring unit 31 of the end of the inquiry. In A28, the monitoring unit 31 receives the notification of the completion of the inquiry and resets the counter for the re-interrogation possible time of the inquiry triggers 1, 2, and 4. In A29, the monitoring unit 31 notifies the recording control unit 32 of the end of the inquiry and instructs the recording end of the vehicle data. Subsequently, in A30, the recording control unit 32 receives the notification of the completion of the inquiry and transmits the collected vehicle data to the customer vehicle management DB 52 of the server 50 via the wireless communication device 35. Subsequently, in A31, the inquiry module 34 transmits the inquiry data, which is the user's answer, to the customer vehicle management DB 52 of the server 50 via the wireless communication device 35. In A32 and A33, the developer accesses the customer vehicle management DB 52 of the server 50 from the developer terminal 70, and acquires the vehicle data and the inquiry data recorded in the customer vehicle management DB 52.

<Effect>
According to the embodiment described above in detail, the following effects can be obtained.
(1) At the timing determined by the inquiry system 100 itself, an inquiry is made to the user, vehicle data is collected, and the answers to the inquiry and the vehicle data at the time of the inquiry are associated with the customer vehicle management DB 52. To be recorded. Therefore, regardless of the user's behavior, the user's feeling and the vehicle data can be obtained in association with each other.

  (2) At least one of the collection conditions and the contents of the inquiry can be changed as appropriate by the developer using the developer terminal 70. Therefore, it is possible to acquire appropriate information according to market needs and the like.

  (3) It is monitored whether or not the user's situation is an interrogative situation, and the interview is executed on the condition that the user's situation is determined to be an interrogative situation. Thereby, the safety of the user can be ensured and the user's answer can be easily obtained.

  (4) By stopping the execution of the interview when the user is performing an emergency operation or immediately after that, it is possible to suppress the user's attention from being warped by the interview, especially when the user needs to concentrate on driving operation. can do. As a result, the safety of the user can be ensured.

  (5) When it is determined that the user situation makes the user uncomfortable by conducting an inquiry, the execution of the inquiry is stopped. Thereby, making a user unpleasant is suppressed and it can make it easy to obtain a user's answer at the time of conducting a next inquiry.

  (6) As the possibility of making the user uncomfortable is higher, a higher degree of difficulty D is set, and the question is not conducted unless there is a priority question that exceeds the difficulty level D. Thereby, it is possible to perform an important inquiry while suppressing the user from being uncomfortable.

(7) Since the user is interrogated only when the user's approval is obtained, it is possible to suppress bothering the user.
(8) By increasing the waiting time until the next inquiry as the degree of rejection of the user's inquiry increases, the user's answer can be easily obtained when the next inquiry is performed.

  (9) By giving a privilege to an answer, the user can be actively prompted to answer. Furthermore, the inquiry system 100 can be used for marketing other than vehicle diagnosis and vehicle development.
