  The characteristic information is preferably usage information related to the use of the in-vehicle device mounted on the vehicle. In particular, the usage information includes information on the usage frequency of the operator when changing the control content, information on the frequency of control content change guidance, information on the frequency of execution of the control content change, and information on the frequency of canceling the control content change. And at least one piece of information related to the operation frequency of the navigation system. In this case, it is possible to set an appropriate guidance method for changing the control content in accordance with the usage characteristics of the in-vehicle device (navigation system or the like) of the user, that is, the proficiency level of the in-vehicle device.

In this case, it is possible to set an appropriate guidance method for changing the control content according to the user's behavior characteristics, that is, the user's situation.

  The characteristic information is preferably driver operation information related to the user's driving operation. In this case, since the user's state (for example, being in a hurry or not in a good mood) can be estimated from the user's driving operation, an appropriate guidance for changing the control content in accordance with the user's state is provided. Can be set.

  The control means is an electronic control device, and the guidance method setting means can set and output a guidance method for changing the program of the electronic control device for the user based on the characteristic information acquired by the characteristic information acquisition means. preferable. According to such a configuration, it is possible to promote the change (update, addition, deletion) of the program of the electronic control unit (ECU) mounted on the vehicle.

It is a center that supports management and monitoring of programming (repro)), addition and deletion. The operator center 2 receives repro guidance data (reprogramming guidance method) transmitted from the vehicle 3 and performs reprogramming guidance according to the repro guidance data. The operator center 2 includes a communication unit 21 that performs data transmission / reception and voice call with the vehicle 3, and a customer information DB (database) 22.

  The customer information DB 22 stores customer information (age, sex, occupation, etc.) regarding the user who owns the vehicle 3. The customer information DB 22 extracts and outputs customer information associated with the vehicle information in response to a request from the vehicle 3.

  The vehicle 3 includes a sensor 31, an actuator 32, a navigation system (on-vehicle equipment) 33, an ECU 34, and a program update guide device (control device) 35.

  The sensor 31 is a part that acquires various state information of the vehicle 3 and information from the outside of the vehicle. Examples of the sensor 31 include a vehicle speed sensor, an accelerator opening sensor, a steering wheel sensor, and a sensor that receives information (congestion information, weather information, etc.) issued from an infrastructure device. The sensor 31 outputs the acquired information to the ECU 34. The actuator 32 is a throttle actuator, a brake actuator, a steering actuator, or the like. The actuator 32 outputs information indicating the control state to the ECU 34.

  The navigation system 33 measures the absolute position on the ground surface of the vehicle 3 by GPS (Global Positioning System), compares it with map information stored separately, identifies the position of the host vehicle on the map, and displays it on the display To do. In the navigation system 33, an input from the user is received and an operation corresponding to the input is performed. The navigation system 33 can perform data communication with the operator center 2 by a communication unit 40 described later. Also, a voice call with the operator center 2 is possible.

  The ECU 34 acquires various information acquired by the sensor 31 and the actuator 32 and acquires operation information of the navigation system 33. The ECU 34 controls the state of the actuator 32. Note that the electronic control unit having the software to be reprogrammed may be the ECU 34 or another ECU (not shown).

  The program update guide device 35 includes a communication unit 40, a learning unit 41, an invariant information DB 42, a variable information DB 43, a life log information DB 44, a characteristic information acquisition unit (characteristic information acquisition unit) 45, and a guidance method setting unit. (Guidance method setting means) 46. The communication unit 40 is a part that performs data transmission / reception and voice call connection with the operator center 2.

  The learning unit 41 is a part that acquires characteristic information and stores it in the DBs 42 to 44 as learning information. The learning unit 41 acquires various information acquired by the sensor 31, the actuator 32, and the navigation system 33, and information output from the communication unit 40, and the invariant information DB 42, the variable information DB 43, and life log information for each information type. Save in DB44. Specifically, the learning unit 41 specifies and selects a database (any one of the invariant information DB 42, the variable information DB 43, and the life log information DB 44) corresponding to the acquired information, and the storage stored in the selected database. The information is compared with the acquired acquired information to determine whether the stored information and the acquired information match, are similar, or are different. The learning unit 41 saves and updates (rewrites) the acquired information and the storage information stored in the database in association with each other based on the determination result.

  Here, a specific operation of the learning unit 41 will be described. FIG. 2 is a flowchart showing the operation of the learning unit. In FIG. 2, the life log information stored in the life log information DB 44 will be described. The details of the life log information will be described later. The life log information is, for example, information related to user life information, behavior history, and driving characteristics.

  As shown in FIG. 2, a storage request to the life log information DB 44 is first executed (step S01). Then, it is determined whether or not life log information is acquired from the sensor 31, the actuator 32, or the like (step S02). If it is determined that the life log information has been acquired, the process proceeds to step S03. On the other hand, if it is not determined that the life log information has been acquired, initial registration is performed (step S04). The initial registration is to make all information stored in the life log information DB 44 be in an initial value state.

  In step S03, it is determined whether or not the navigation system 33 is operated. If it is determined that there is an operation of the navigation system 33, the process proceeds to step S05. On the other hand, if it is not determined that there is an operation of the navigation system 33, the process proceeds to step S06.

  In step S05, it is determined whether or not there is an operation history operated in the past in the navigation system 33. If it is determined that there is an operation history of the navigation system 33, the number of operations is added to the operation history information, and the information is saved (stored) in the life log information DB 44 (step S07). On the other hand, when it is not determined that there is an operation history of the navigation system 33, the information is stored in the life log information DB 44 as a new operation (step S08).

  In step S06, it is determined whether or not there is a driving operation by the user. If it is determined that there is a driving operation, driving characteristic information and driving history information related to the user's driving are acquired and stored in the life log information DB 44 (step S09). On the other hand, if it is not determined that there is a driving operation, a state change standby is set (step S10). As described above, the learning unit 41 acquires life log information that is driving characteristic information and stores it in the life log information DB 44.

  Returning to FIG. 1, the invariant information DB 42 is a database that stores user invariant information. The invariant information DB 42 stores information that does not change in a short period of time, such as age, sex, occupation, and the like. The invariant information DB 42 stores invariant information acquired from the customer information DB 22 of the operator center 2 or input and acquired by an input means (for example, the navigation system 33) mounted on the vehicle 3.

  The variable information DB 43 is a database that stores user variable information. The variable information includes usage information of the navigation system 33, and frequently (in a short period of time) such as the usage frequency of the operator of the operator center 2, the number of repro implementations (rejection count), the number of repro guidance, the operation frequency of the navigation system 33, etc. ) Information to be changed is stored.

  The life log information DB 44 is a database that stores life log information such as behavior history that is user life information and behavior information, driving characteristics that are driver operation information, and the like. The life information is, for example, daily behavior patterns, the behavior history of the vehicle 3 that is behavior information is, for example, a destination (route information) in the vehicle, and the driving characteristics that are driver operation information are, for example, accelerator, brake , Handle operation and the like.

  The characteristic information acquisition unit 45 is a part for acquiring user characteristic information. The characteristic information acquisition unit 45 acquires various types of information stored in the invariant information DB 42, the variable information DB 43, and the life log information DB 44. The characteristic information acquisition unit 45 outputs the acquired characteristic information to the guidance method setting unit 46.

  The guidance method setting unit 46 is a part that sets a program update guidance method for the user based on the user characteristic information. Upon receiving the characteristic information (invariant information, variable information, life log information) output from the characteristic information acquisition unit 45, the guidance method setting unit 46 specifies the basic attribute of the guidance method based on the invariant information, The guidance method is corrected based on the life log information. The guidance method setting unit 46 outputs repro guidance data indicating the set guidance method to the communication unit 40. As a result, the repro guidance data is transmitted to the operator center 2 by the communication unit 40.

  Next, the operation of the program update guide device 35 will be described. FIG. 3 is a flowchart showing the operation of the program update guidance device.

  As shown in FIG. 3, when it is confirmed that the engine of the vehicle 3 is started (step S11), personal information acquisition processing is performed by the learning unit 41 (step S12). The personal information acquisition process will be described with reference to FIG. FIG. 4 is a flowchart showing personal information acquisition processing.

  As shown in FIG. 4, in the personal information acquisition process, first, a personal information request for requesting personal information (age, sex, occupation, etc.) from the invariant information DB 42 is performed (step S31). Next, it is determined whether or not personal information has been acquired from the invariant information DB 42 (step S32). If it is determined that personal information has been acquired, the process proceeds to step S33. On the other hand, if it is not determined that personal information has been acquired, the process proceeds to step S34.

  In step S33, it is determined whether or not an information shortage flag is set in the invariant information DB. If it is determined that the information shortage flag is set, the process proceeds to step S34. On the other hand, if it is not determined that the information shortage flag is set, the process ends as the personal information is acquired.

  In step S34, it is determined whether or not new input of personal information is possible by the user. If it is determined that a new input is possible, the personal information acquired by the input is stored in the invariant information DB 42 in association with the user identification information (user ID) (step S35). On the other hand, if it is not determined that a new input is possible, the process proceeds to step S36.

  In step S36, it is determined whether or not personal information can be acquired from the customer information DB 22 of the operator center 2. If it is determined that personal information can be acquired from the customer information DB 22, the process proceeds to step S35. On the other hand, if it is not determined that the personal information can be acquired from the customer information DB 22, the process proceeds to step S37.

  In step S37, it is determined whether or not personal information can be acquired from an ETC card inserted in an ETC (Electronic Toll Collection System) mounted on the vehicle 3. If it is determined that personal information can be acquired from the ETC card, the process proceeds to step S35. On the other hand, if it is not determined that the personal information can be acquired from the ETC card, the process proceeds to step S38.

  In step S38, it is determined whether there is any missing information (insufficient information) in the personal information. If it is determined that there is no shortage information, the process ends. On the other hand, if it is not determined that there is no shortage information, an information shortage flag is set in the variable information DB 43 (step S39). As described above, the personal information acquisition process is performed.

  Returning to FIG. 3, when the personal information acquisition process is executed, it is determined by the characteristic information acquisition unit 45 whether or not personal information has been acquired from the invariant information DB 42 (step S13). If it is determined that personal information has been acquired from the invariant information DB 42, the process proceeds to step S14. On the other hand, if it is not determined that personal information has been acquired from the invariant information DB 42, the process proceeds to step S15.

  In step S14, the guidance method setting unit 46 identifies the basic attributes of the reprogramming guidance method. Specifically, this will be described with reference to FIG. FIG. 5 is a diagram for explaining identification of basic attributes based on personal information. In the table shown in FIG. 5, “item”, “type”, and “weight” are stored in association with each other. “Item” includes “sex”, “age”, and “occupation”, which are personal information, and is associated with “type”. Specifically, “male” and “female” are associated with “sex”, and “age” is “20-30s”, “40-50s”, “60s” Are associated, and “occupation” is associated with “technical position” and “office work position”. “Type” is associated with, for example, “weight” which is a criterion for determining whether or not the operation of the navigation system 33 is good. The “weight” is assigned in three stages of 0 to 2.

  The guidance method setting unit 46 determines whether the user is good at the operation of the navigation system 33 based on the sum of the points of “weight”, and determines the basic policy (navigation guidance, operator guidance) of the reprogramming guidance method based on the determination result. Select and identify. When the “weight” exceeds a certain value (for example, “3”), the guidance method setting unit 46 determines that the user is good at the operation of the navigation system 33 and selects the navigation guidance. If the “weight” does not exceed a certain value, the user determines that the operation of the navigation system 33 is unfamiliar and selects operator guidance.

  Specifically, for example, when the personal information acquired by the characteristic information acquisition unit 45 indicates “30s”, “female”, and “technical position”, the guidance method setting unit 46 sets “weight”. Since the total is “4”, it is determined that the operation of the navigation system 33 is good, and the navigation system 33 selects a basic policy for guiding reprogramming. For example, when the personal information acquired by the characteristic information acquisition unit 45 indicates “60s”, “male”, and “office work”, the guidance method setting unit 46 sets the total “weight” to “1”. Therefore, it is determined that the operation of the navigation system 33 is unfamiliar, and a basic policy for guiding reprogramming is selected by operator guidance. As described above, the basic method attribute of the reprogramming guidance method is specified by the guidance method setting unit 46.

  Returning to FIG. 3, in step S <b> 15, the variable information acquisition process is performed by the characteristic information acquisition unit 45. The variable information acquisition process will be described with reference to FIG. FIG. 6 is a flowchart showing variable information acquisition processing.

  As shown in FIG. 6, in the variable information acquisition process, first, a variable information request is made to request variable information (operator use count, repro execution count, repro guidance count, etc.) from the variable information DB 43 (step S41). Next, it is determined whether or not variable information has been acquired from the variable information DB 43 (step S42). If it is determined that variable information has been acquired, the process proceeds to step S43. On the other hand, if it is not determined that variable information has been acquired, initial registration is performed (step S44). The initial registration is to make all information stored in the variable information DB 43 be in an initial value state.

  In step S43, it is determined whether there is a record of use of the operator of the operator center 2 in the invariant information. If it is determined that the operator is used, the number of times the operator is registered in the variable information DB 43 is changed, and the changed information is stored in the variable information DB 43 (step S45). On the other hand, if it is not determined that the operator is using, the process proceeds to step S46.

  In step S46, it is determined whether or not there is a reprogramming guidance record in the invariant information. If it is determined that there is reprogramming guidance, the number of reprogramming guidances registered in the variable information DB 43 is changed, and the changed information is stored in the variable information DB 43 (step S47). On the other hand, if it is not determined that there is reprogramming guidance, the process proceeds to step S48.

  In step S48, it is determined whether or not reprogramming has a track record in the invariant information. If it is determined that reprogramming has been performed, the number of reprogramming cancellations registered in the variable information DB 43 is changed, and the changed information is stored in the variable information DB 43 (step S49). . On the other hand, if it is not determined that reprogramming has been performed, the process proceeds to step S50.

  In step S50, it is determined whether or not the reprogramming is performed under the guidance of the operator. If it is determined that the operation is based on the guidance of the operator, the number of reprogramming operations performed by using the operator is changed, and the changed information is stored in the variable information DB 43 (step S51). On the other hand, if it is not determined that the execution is based on the guidance of the operator, the number of reprogramming executions without using the operator is changed, and the changed information is stored in the variable information DB 43 (step S52). As described above, the variable information acquisition process is performed.

  Returning to FIG. 3, when the variable information acquisition process is executed, it is determined by the characteristic information acquisition unit 45 whether or not variable information has been acquired from the variable information DB 43 (step S16). If it is determined that variable information has been acquired from the variable information DB 43, the process proceeds to step S17. On the other hand, if it is not determined that variable information has been acquired from the variable information DB 43, the process proceeds to step S18.

  In step S <b> 17, guidance method correction processing is performed by the guidance method setting unit 46. FIG. 7 is a flowchart showing guidance method correction processing, and FIG. 8 is a diagram illustrating guidance method correction processing.

  As shown in FIG. 7, in the guidance method correction process, it is first determined based on the variable information whether or not the reprogramming guidance is the first time (step S61). If it is determined that the reprogramming guidance is the first time, the process proceeds to step S62. On the other hand, if it is not determined that the reprogramming guidance is the first time, correction based on past results is performed (step S63).

  In step S62, whether or not there is a usage history of the operator is determined based on the variable information. If it is determined that there is a usage history of the operator, guidance from the operator is selected (step S64). On the other hand, when it is not determined that there is a usage history of the operator, initial guidance according to the basic policy is selected (step S65). As shown in FIG. 8, the guidance method setting unit 46 corrects the guidance method according to the number of reprogramming operations. Specifically, the guidance method setting unit 46 selects and corrects the attribute of the guidance method based on the number of reprogramming executions and the number of reprogramming guidances.

  Returning to FIG. 3, in step S <b> 18, life log information acquisition processing is performed by the learning unit 41. The life log information acquisition process will be described with reference to FIGS. 9 and 10 are flowcharts showing the life log information acquisition process.

  As shown in FIG. 9, in the life log information acquisition process, first, a life log information request is made to request life log information (life information, driving characteristic information, travel history information, etc.) from the life log information DB 44 (step S71). ). Next, it is determined whether or not life log information has been acquired from the life log information DB 44 (step S72). If it is determined that the life log information has been acquired, the process proceeds to step S73. On the other hand, if it is not determined that the life log information has been acquired, initial registration is performed (step S74). The initial registration is to make all information stored in the life log information DB 44 be in an initial value state.

  In step S <b> 73, it is determined whether there is navigation operation information related to the operation of the navigation system 33. If it is determined that there is navigation operation information, the process proceeds to step S75. On the other hand, if it is not determined that there is navigation operation information, the process proceeds to step S76.

  In step S75, the total number of operations of the past navigation system 33 is acquired. Then, the total number of operations is compared with the type of operation of the navigation system 33 (step S77), and it is determined whether or not only a specific operation (for example, setting of a destination) is performed (step S78). . If it is determined that only a specific operation is being performed, the operation support level of the navigation system 33 is determined to be “low” (step S79), and information indicating that is stored. On the other hand, if it is not determined that only a specific operation is being performed, the operation support level of the navigation system 33 is determined to be “high” (step S80), and information indicating that is stored.

  In step S76, it is determined whether or not there is driving characteristic information related to the user's driving operation. If it is determined that there is driving characteristic information, the process proceeds to step S81. On the other hand, if it is not determined that there is driving characteristic information, the process proceeds to step S82.

  In step S81, it is determined whether or not the difference in information is large when the acquired driving characteristic information is compared with the driving characteristic information of the history information. When it is determined that the deviation of the driving characteristic information is large, it is determined that the state of the user is “abnormal state” such as “emergency” or “physical condition” (step S82), and this is indicated. Information is stored. On the other hand, when it is not determined that the deviation of the driving characteristic information is large, the user's state is determined to be “normal state” (step S83), and information indicating that is stored.

  As shown in FIG. 10, in step S82, it is determined whether or not there is driving history information related to the driving history of the user. If it is determined that there is driving history information, the process proceeds to step S84. On the other hand, if it is not determined that there is driving history information, the process proceeds to step S85. In step S84, it is determined whether or not the vehicle 3 is regularly used based on the driving history information. For regular use, weekday and holiday hours are also taken into account. If it is determined that the vehicle 3 is regularly used, information regarding the distance to the destination is stored (step S86). On the other hand, if it is not determined that the vehicle 3 is regularly used, the process proceeds to step S87.

  In step S87, it is determined whether or not the destination is set in the navigation system 33. If it is determined that there is a destination setting, information regarding the distance to the destination is stored (step S88). On the other hand, if it is not determined that there is a destination setting, it is determined that the distance is not necessary for setting the destination (for example, a short distance), and the process ends.

  In step 85, it is determined whether there is weather information. If it is determined that there is weather information, the weather information is stored in the life log information DB 44 (step S89). If it is not determined that there is weather information, the process ends. Life log information acquisition processing is performed.

  Returning to FIG. 3, when the life log information acquisition process is executed, the characteristic information acquisition unit 45 determines whether or not the life log information is acquired from the life log information DB 44 (step S19). When it is determined that the life log information is acquired from the life log information DB 44, the process proceeds to step S20. On the other hand, if it is not determined that the life log information is acquired from the life log information DB 44, the process proceeds to step S21.

  In step S <b> 20, a guidance technique correction process is performed by the guidance technique setting unit 46. FIG. 11 is a flowchart illustrating the guidance method correction process.

  As shown in FIG. 11, in the guidance method correction process, it is first determined whether or not weather information has been acquired (step S90). If it is determined that the weather information has been acquired, the process proceeds to step S91. On the other hand, if it is not determined that the weather information has been acquired, the process proceeds to step S92. In step S91, it is determined whether the weather information indicates bad weather (for example, rain, snow). If it is determined that the weather is bad, the reprogramming guidance is canceled (step S93). On the other hand, if it is not determined that the weather is bad, the process proceeds to step S92.

  In step S92, it is determined whether or not the difference between the acquired operation characteristic and the characteristic during normal operation is large. If it is determined that the deviation is large, the process proceeds to step S93. On the other hand, when it is not determined that the deviation is large, it is determined whether or not the behavior pattern is a daily life (step S94). When it is determined that the behavior pattern is a daily life pattern, a reprogramming guidance method setting process is performed (step S95). On the other hand, when it is determined that the action pattern is a daily life, it is determined whether or not the driving is a long distance (long time) (step S96). If it is determined that the operation is a long distance, the process proceeds to step S95. On the other hand, if it is not determined that the driving is a long distance, the process proceeds to step S93. As described above, the correction process for the guidance method is performed.

  Returning to FIG. 3, in step S21, a guidance method for a reprogramming user is set based on the guidance policy determined in each process. Thus, the reprogramming guidance method is set.

  As described above, in the program update guidance device 35, the characteristic information of the user of the vehicle 3 is acquired by the characteristic information acquisition unit 45, and the guidance method of the program update for the user based on this characteristic information is provided by the guidance method setting unit 46. Set. For example, in the program update guidance device 35, when the user is elderly based on personal information (invariant information) that is characteristic information, it is considered that the user is not used to the operation of the navigation system 33. Set the method to be implemented. Further, when the user is a woman, the operation of the navigation system 33 is accustomed, but there is a possibility that the user feels anxiety and confusion about the guidance. Therefore, a method of performing guidance only for the first time is set. Further, when the user is a male, it is considered that he is relatively used to operating the device. Therefore, the implementation of the guidance method is set based on information such as the operation history of the navigation system 33.

  Further, the program update guidance device 35 further corrects the guidance method set in the personal information based on the variable information that is the characteristic information. Specifically, in the program update guidance device 35, a method for directly performing guidance is set for a user who frequently uses an operator.
