Hereinafter, the vehicle information retrieval method and the vehicle information retrieval apparatus according to the present invention will be described in detail with reference to the accompanying drawings, citing suitable embodiments.

[1. Vehicle information retrieval device 10]
The vehicle information retrieval device 10 shown in FIG. 1 is provided in the interior of the vehicle. The vehicle information retrieval device 10 includes an input unit 12, a calculation unit 14, a storage unit 16, and a notification unit 18.

The input unit 12 is an HMI (human machine interface) that can be operated by the user, and has an input device. The input device of this embodiment is a touch panel 20. The input unit 12 may be a keyboard or the like, or may be a voice input device having a microphone or the like. The input unit 12 accepts a keyword that the user wants to search. This keyword is referred to as a search keyword 22. The touch panel 20 inputs the search keyword 22 to the calculation unit 14.

The arithmetic unit 14 has a processor. The arithmetic unit 14 realizes various functions by executing a program stored in the storage unit 16. In the present embodiment, the calculation unit 14 functions as a search unit 24, a collation unit 26, an alternative keyword generation unit 28, and a display control unit 30. The search unit 24 searches the database stored in the storage unit 16 using the keyword (search keyword 22 or alternative keyword 32) as a search condition. The collation unit 26 collates the search keyword 22 with the specific keyword 44 stored in the storage unit 16. The alternative keyword generation unit 28 generates an alternative keyword 32 in place of the search keyword 22. The display control unit 30 controls the display device 46 of the notification unit 18.

The storage unit 16 has various storage devices (RAM, ROM, hard disk, etc.). The storage unit 16 stores a program or the like executed by the arithmetic unit 14. Further, the storage unit 16 stores a vehicle information database 34 (referred to as a vehicle information DB 34). The vehicle information DB 34 stores the word 36 related to the vehicle and the vehicle information 38 related to the word 36 in association with each other. The vehicle information 38 is a description of the word 36, or includes a description of the function and operation method of the vehicle using the word 36. The vehicle information 38 is given a title 40. Further, the storage unit 16 stores the keyword database 42 (referred to as the keyword DB 42). The keyword DB 42 stores keywords having similar meanings or names in association with each other. Further, the storage unit 16 stores one or more specific keywords 44.

The specific keyword 44 has a meaning similar to that of the word 36 in which the information is stored in the vehicle information DB 34, and means a keyword in which the information is not stored in the vehicle information DB 34. For example, "driving support" and "autonomous driving" are in agreement with each other in that the system controls the vehicle, but the contents of the vehicle control are different. Here, it is assumed that the information of "driving support" is accumulated in the vehicle information DB 34 and the information of "automatic driving" is not accumulated. When the user inputs the search keyword 22 "automatic driving" and the information of "driving support" is provided instead of the information of "automatic driving", the user changes the information of "driving support" to the information of "automatic driving". There is a risk of misunderstanding. In the present embodiment, a keyword that may give a misunderstanding to the user by providing the vehicle information 38 associated with the word 36 is stored in the storage unit 16 in advance as a specific keyword 44.

The notification unit 18 is an HMI that notifies the user of information, and has a display device 46. A touch panel 20 is attached to the display device 46. The display device 46 displays various information. The notification unit 18 may have an audio device such as a speaker in addition to the display device 46.

[3. Vehicle information search process]
[3.1. First Embodiment]
The first embodiment of the vehicle information search process executed by the vehicle information search device 10 will be described with reference to FIG. When the user inputs the search keyword 22 in the search window 56 of the input screen 48 shown in FIG. 2 and presses the search button 58, the vehicle information search process described below is started.

In step S1, the touch panel 20 inputs (transmits) the search keyword 22 to the calculation unit 14. When step S1 is completed, the process proceeds to step S2.

In step S2, the search unit 24 searches the vehicle information DB 34 using the keyword as a search condition. When the alternative keyword 32 has not been generated (when step S7 or step S9 has not been performed yet), the search unit 24 searches the vehicle information DB 34 using the input search keyword 22 as a search condition. On the other hand, when the alternative keyword 32 is generated (when step S7 or step S9 has already been performed), the search unit 24 searches the vehicle information DB 34 using the generated alternative keyword 32 as a search condition. The search unit 24 collates the keyword used as the search condition with the word 36, and searches for the word 36 corresponding to (matching) the keyword. When the step S2 is completed, the process proceeds to the step S3.

In step S3, the search unit 24 determines whether or not the word 36 corresponding to the keyword exists in the vehicle information DB 34. If there is a word 36 corresponding to the keyword (step S3: yes), the process proceeds to step S4. On the other hand, when there is no word 36 corresponding to the keyword (step S3: none), the process proceeds to step S5.

In step S4, the display control unit 30 outputs (transmits) the display instruction of the search result screen 54 (FIG. 5) to the display device 46. At this time, the display control unit 30 outputs (transmits) the title 40 of the vehicle information 38 associated with the word 36 to the display device 46. Then, the display device 46 displays the search result screen 54. On the search result screen 54, one or more display instruction buttons 66 with the title 40 are displayed.

In this state, when the user presses any of the display instruction buttons 66, the display control unit 30 outputs (transmits) the display instruction of the vehicle information screen (not shown) to the display device 46. At this time, the display control unit 30 reads the vehicle information 38 corresponding to the title 40 from the vehicle information DB 34 and outputs (transmits) it to the display device 46. Then, the display device 46 displays the vehicle information 38 on the vehicle information screen and notifies the user of the vehicle information 38. When step S4 is completed, the vehicle information retrieval process is completed.

In step S5, the collation unit 26 collates the keyword (search keyword 22 or alternative keyword 32) with the specific keyword 44. When the step S5 is completed, the process proceeds to the step S6.

In step S6, the collation unit 26 determines whether or not the keyword (search keyword 22 or alternative keyword 32) matches the specific keyword 44. When the keyword matches the specific keyword 44 (step S6: YES), the process proceeds to step S7. On the other hand, when the keyword does not match the specific keyword 44 (step S6: NO), the process proceeds to step S9.

In step S7, the alternative keyword generation unit 28 generates the alternative keyword 32. Here, the alternative keyword generation unit 28 searches the keyword DB 42 using the keyword (search keyword 22 or alternative keyword 32) as a search condition. Then, the alternative keyword generation unit 28 reads another keyword associated with the keyword used as the search condition from the keyword DB 42, and sets it as the alternative keyword 32. When step S7 is completed, the process proceeds to step S8.

In step S8, the display control unit 30 outputs (transmits) the display instruction of the first word guidance screen 50 (FIG. 3) to the display device 46. At this time, the display control unit 30 outputs (transmits) the keyword (search keyword 22 or alternative keyword 32) and the alternative keyword 32 in place of the keyword to the display device 46. Then, the display device 46 displays the first word guidance screen 50 and notifies the user of the message 62 and the alternative keyword 32. When step S8 is completed, the process proceeds to step S11.

In step S9, the alternative keyword generation unit 28 generates the alternative keyword 32 in the same manner as in step S7. When the step S9 is completed, the process proceeds to the step S10.

In step S10, the display control unit 30 outputs (transmits) the display instruction of the second word guidance screen 52 (FIG. 4) to the display device 46. At this time, the display control unit 30 outputs (transmits) the keyword (search keyword 22 or alternative keyword 32) and the alternative keyword 32 in place of the keyword to the display device 46. Then, the display device 46 displays the second word guidance screen 52 and notifies the user of only the alternative keyword 32. When the step S10 is completed, the process proceeds to the step S11.

In step S11, the search unit 24 determines whether or not the user has executed the search, specifically, whether or not the re-search button 64 included in the first word guidance screen 50 or the second word guidance screen 52 is pressed. Is determined. When the operation signal transmitted from the touch panel 20 is input when the re-search button 64 is pressed (step S11: YES), the process returns to step S2. On the other hand, when the operation signal transmitted from the touch panel 20 is not input or the end process is performed (step S11: NO), the vehicle information search process ends.

[3.2. Second Embodiment]
A second embodiment of the vehicle information retrieval process executed by the vehicle information retrieval device 10 will be described with reference to FIG. 7. In the first embodiment, after the search unit 24 searches the vehicle information DB 34, the collation unit 26 performs keyword collation (step S2-step S5). On the other hand, in the second embodiment, after the collation unit 26 collates the keywords, the search unit 24 searches the vehicle information DB 34 (step S22-step S26). When the user inputs the search keyword 22 in the search window 56 of the input screen 48 shown in FIG. 2 and presses the search button 58, the vehicle information search process described below is started.

In step S21, the touch panel 20 inputs (transmits) the search keyword 22 to the calculation unit 14. When the step S21 is completed, the process proceeds to the step S22.

In step S22, the collation unit 26 collates the keyword (search keyword 22 or alternative keyword 32) with the specific keyword 44. When the alternative keyword 32 is not generated (when steps S24 and S29 have not been performed yet), the collation unit 26 collates the search keyword 22 with the specific keyword 44. On the other hand, when the alternative keyword 32 is generated (when steps S24 and S29 have already been performed), the collation unit 26 collates the alternative keyword 32 with the specific keyword 44. When the step S22 is completed, the process proceeds to the step S23.

In step S23, the collation unit 26 determines whether or not the keyword (search keyword 22 or alternative keyword 32) matches the specific keyword 44. If the keyword matches the specific keyword 44 (step S23: YES), the process proceeds to step S24. On the other hand, when the keyword does not match the specific keyword 44 (step S23: NO), the process proceeds to step S26.

In step S24, the alternative keyword generation unit 28 generates the alternative keyword 32. Here, the alternative keyword generation unit 28 searches the keyword DB 42 using the keyword (search keyword 22 or alternative keyword 32) as a search condition. Then, the alternative keyword generation unit 28 reads another keyword associated with the keyword used as the search condition from the keyword DB 42, and sets it as the alternative keyword 32. When step S24 is completed, the process proceeds to step S25.

In step S25, the display control unit 30 outputs (transmits) the display instruction of the first word guidance screen 50 (FIG. 3) to the display device 46. At this time, the display control unit 30 outputs (transmits) the keyword (search keyword 22 or alternative keyword 32) and the alternative keyword 32 in place of the keyword to the display device 46. Then, the display device 46 displays the first word guidance screen 50 and notifies the user of the message 62 and the alternative keyword 32. When step S25 is completed, the process proceeds to step S31.

In step S26, the search unit 24 searches the vehicle information DB 34 using the keyword as a search condition. When the alternative keyword 32 is not generated (when step S24 or step S29 has not been performed yet), the search unit 24 searches the vehicle information DB 34 using the input search keyword 22 as a search condition. On the other hand, when the alternative keyword 32 is generated (when step S24 or step S29 has already been performed), the search unit 24 searches the vehicle information DB 34 using the alternative keyword 32 as a search condition. The search unit 24 collates the keyword used as the search condition with the word 36, and searches for the word 36 corresponding to (matching) the keyword. When step S26 is completed, the process proceeds to step S27.

In step S27, the search unit 24 determines whether or not the word 36 corresponding to the keyword exists in the vehicle information DB 34. If there is a word 36 corresponding to the keyword (step S27: yes), the process proceeds to step S28. On the other hand, when there is no word 36 corresponding to the keyword (step S27: none), the process proceeds to step S29.

In step S28, the display control unit 30 outputs (transmits) the display instruction of the search result screen 54 (FIG. 5) to the display device 46. At this time, the display control unit 30 outputs (transmits) the title 40 of the vehicle information 38 associated with the word 36 to the display device 46. Then, the display device 46 displays the search result screen 54. On the search result screen 54, one or more display instruction buttons 66 with the title 40 are displayed.

In this state, when the user presses any of the display instruction buttons 66, the display control unit 30 outputs (transmits) the display instruction of the vehicle information screen (not shown) to the display device 46. At this time, the display control unit 30 reads the vehicle information 38 corresponding to the title 40 from the vehicle information DB 34 and outputs (transmits) it to the display device 46. Then, the display device 46 displays the vehicle information 38 on the vehicle information screen and notifies the user of the vehicle information 38. When the step S28 is completed, the vehicle information search process is completed.

In step S29, the alternative keyword generation unit 28 generates the alternative keyword 32 in the same manner as in step S24. When step S29 is completed, the process proceeds to step S30.

In step S30, the display control unit 30 outputs (transmits) the display instruction of the second word guidance screen 52 (FIG. 4) to the display device 46. At this time, the display control unit 30 outputs (transmits) the keyword (search keyword 22 or alternative keyword 32) and the alternative keyword 32 in place of the keyword to the display device 46. Then, the display device 46 displays the second word guidance screen 52 and notifies the user of only the alternative keyword 32. When the step S30 is completed, the process proceeds to the step S31.

In step S31, the search unit 24 determines whether or not the user has executed the search, specifically, whether or not the re-search button 64 included in the first word guidance screen 50 or the second word guidance screen 52 is pressed. Is determined. When the operation signal transmitted from the touch panel 20 is input when the re-search button 64 is pressed (step S31: YES), the process returns to step S22. On the other hand, when the operation signal transmitted from the touch panel 20 is not input or the end process is performed (step S31: NO), the vehicle information search process ends.
