It is determined whether or not the current addition data obtained by the addition in step S17 is larger than the threshold value set as the addition data in advance. If the current addition data is larger than the threshold value, the process proceeds to step S19, and if it is not larger, the process proceeds to step S23. Here, the threshold value is set to a value for determining that it is necessary to present the presentation data based on the current addition data.

In step S19, the determination unit 13 determines that
Steps S12 to S18 for a plurality of conditional statements
As a result of performing the process of step S13, step S1
4, step S15, step S16 and step S1
It is determined whether or not there is another conditional statement that is determined to be “yes” in the determination process of No. 8, and when another conditional statement is detected, the process proceeds to step S20, and another conditional statement is not detected. If determined, the process proceeds to step S23.

In step S20, the determination section 13 determines that
The priority information of the conditional statement currently acquired as a target of processing in step S12 is compared with the priority information of the other conditional statements previously detected in step S19, and the condition currently processed is compared. If the priority of the sentence is higher than that of other conditional sentences, the process proceeds to step S21. If not, the process proceeds to step S23.

In step S21, the determination section 13 determines that
The conditional sentence number of the conditional sentence which is determined to have a high priority in step S20 and which is the current processing target is changed to the conditional sentence number of the conditional sentence to be presented, and the process proceeds to step S23.

In step S23, the determination section 13 determines that
As a result of performing the above-described processing for the conditional statement currently being processed, it is determined whether or not the conditional statement with the next conditional statement number exists, and if there is, the next conditional statement number is designated and step S12 is performed. Processing is returned to step S24, and if not present, the processing proceeds to step S24.

As a result, the determination unit 13 sequentially updates the conditional statement numbers to be processed and repeats the processing of step S12 and subsequent steps, thereby performing the processing of step S12 and subsequent steps for all conditional statements included in the information presentation database. By doing so, the conditional sentence number including the presentation data to be presented is acquired.

In step S24, the judgment section 13
It is determined whether or not to present information using the presentation data by determining whether or not the conditional sentence that is the conditional sentence number to be presented in step S21 exists. When the conditional sentence number for presenting information is present, the process proceeds to step S25, and when the conditional sentence number for presenting information is not present, the process is ended.

In step S25, the presentation data included in the conditional sentence determined to be presented by the determination unit 13 in step S24 is read from the database storage unit 3 and output to the presentation processing unit 14 as a determination result. In response to this, the presentation processing unit 14 causes the display unit 5 or the acoustic output unit 6 to perform information presentation using the input presentation data, and then the step S
The process proceeds to 26.

At step S26, the determination section 13 determines that
The system state information of the conditional sentence including the presentation data presented in step S25 is changed to the system state setting information corresponding to the conditional sentence number, and the process proceeds to step S27. That is, every time the presentation data is presented, the system state is changed to the numerical value of the system setting state information.

In step S27, the determination section 13 determines that
The next scenario number information and the next scene number information included in the conditional sentence presented in step S25 are referred to, the scenario number and the scene number to be presented next are set, and the process proceeds to step S28.

In step S28, the determination section 13 determines that
The current addition data included in the conditional statement presented in step S25 is initialized (= 0), and the process ends.

In such presentation data determination processing, the processing of steps S1 to S7 in FIG. 3 is repeatedly performed to repeatedly present or switch the information according to the determination result determined by the determination unit 13. You can

[Example of Information Presentation by Information Providing Device] Next, an example of presenting information to the vehicle driver by the information providing device performing the above-described processing will be described with reference to the contents of the information presenting database of FIGS. 5 and 2. Will be described with reference to. In the example shown in FIG. 5, the route is set in advance by the navigation system, and the vehicle travels in accordance with the route setting. Description will be made assuming that scenes change.

According to FIG. 5, first, at time t1, when the vehicle driver gets on and operates the start switch or the ignition switch of the information providing apparatus to start the system, the presentation data determination process (steps S5 and S1) is performed.
By performing steps 1 to S28) by the determination unit 13, the display unit 5 and the sound output unit 6 present the narrative of the conditional sentence number "1" immediately after boarding (Step S3).
1). Here, it is assumed that the condition statement number “1”, the scenario number “1”, and the scene number “1” are set as initial settings.

When the talking immediately after boarding is finished, the process of step S27 is performed, and the next scenario number "1" of the conditional sentence number "1" and the next scene number "2" are presented. Set to the scene number. Then, in step S12, the traffic information included in the conditional sentence of the conditional sentence number "2" of the scenario number "1" and the scene number "2" is presented (step S32).

Next, at time t2, the scene information indicating that the scene is normal driving is input from the calculating unit 12 to the determining unit 13, and the scene transitions from immediately after boarding to normal driving.
In response to this, the determination process of step S15 is performed by the determination unit 13
By doing so, the condition sentence number “3” set in the scene information of the normal traveling scene is detected. Then, the judgment unit 13 detects the condition sentence number “7” from the next scenario number “2” of the condition sentence number “3” and the next scene number “1” to present a normal narrative (step S3).
3). Next, from the next scenario number “2” and the next scene number “2” included in the conditional sentence number “7”, the determination unit 1
The condition sentence number "8" is detected by 3 and the normal song "1" is presented (step S34).

While the normal music "1" of the scene included in the normal running scenario is being presented, the vehicle speed is 120 [k] according to the speed information from the calculation unit 12 at time t3.
m / h] or more, the determination unit 13 detects the conditional sentence number “26” by the determination processing in step S16. Then, the condition sentence number “8” currently presented
It is determined in the determination processing of step S20 that the priority "A" of the conditional sentence number "26" is set higher than the priority "C" of step S20, and the speed warning is switched and presented (step S3).
5). Here, when the speed alarm is presented while the normal song “1” is presented, the determination unit 13 frequently presents the normal song as compared with other scenes, The system state setting information is set to the numerical value "1", assuming that the presented normal song "1" has already been presented.

When the speed alarm is presented, the scene information from the arithmetic unit 12 is in the normal state, and the system state setting information included in the conditional sentence number “7” and the conditional sentence number “8” becomes the numerical value “1”. Since it has been set, the normal song "2" included in the conditional sentence number "9" is presented (step S36).

At the next time t4, the scene information indicating that the vehicle is traveling on the seaside is generated by the calculation unit 12 and input by the determination unit 13, and at time t4, the scene is seaside traveling from the calculation unit 12. The scene information indicating that is input by the determination unit 13, and the scene transitions from normal running to seaside running. In response to this, the determination unit 13 detects the conditional sentence number “4”. Next, from the next scenario number “3” of the condition sentence number “4” and the next scene number “1”, the judgment unit 13 presents the narrative of the seaside of the condition sentence number “11” (step S37). Then, the conditional sentence number "1
The song "1" on the beach of "2" is presented (step S38).
Here, the determination unit 13 sets the numerical value of the system state setting information of each conditional sentence included in the information presentation database to “0” in response to the scene transitioning from normal traveling to seaside traveling.

While the song "1" on the seaside of the scene included in the seaside traveling scenario is being presented, the vehicle speed is 120 [k] according to the speed information from the calculation unit 12 at time t5.
m / h] or more, when the determination unit 13 detects the conditional sentence number “26” in the determination processing of step S16, a speed warning is presented (step S39).
Here, in the determination unit 13, when the speed warning is presented while presenting the seaside song "1", the frequency of presenting the seaside song "1" is higher than that in the normal driving scene. Since the value is low, the system state setting information is held as the numerical value “0” because the seaside song “1” presented when the scene is traveling by the sea is not presented yet.

As a result, after the speed alarm is presented,
After the warning of the condition sentence number "13", the seaside song "1" is presented (step S40), and subsequently the seaside song "2" of the condition sentence number "14" is presented (step S41).

At time t6, the scene information indicating that the scene is traveling at high speed is input from the calculating unit 12 to the determining unit 13, and the scene transits from seaside traveling to high speed traveling. In response to this, the determination unit 13 detects the high-speed traveling scene of the conditional sentence number “5” and then presents the high-speed narrative of the conditional sentence number “17” (step S42). Then, the seaside song “1” of the conditional sentence number “18” (step S43),
The seaside song "2" of the condition sentence number "19" is presented (step S44).

At time t7, the scene information indicating that the scene is normal running is input from the calculating unit 12 to the determining unit 13, and the scene transitions from high speed running to normal running. In response to this, the determination unit 13 presents a normal narrative (step S45), and then presents a normal song "1" (step S46).

At time t8 when the normal music "1" is being presented, the vehicle speed is 30 [based on the speed information, the addition data (threshold value) and the current addition data generated by the arithmetic unit 12. It is determined by the determination process in step S18 that the state of not more than km / h] has continued for 200 seconds or more.
If it is detected in step 1, the determination unit 13 detects the conditional sentence number “28”. Then, the condition sentence number “1 currently presented”
It is determined in step S20 that the priority "A" of the conditional sentence number "28" is set higher than the priority "C" of 2 ", and the congestion warning is switched and presented. Thereby, the presentation processing unit 14 acquires and presents traffic information from the outside (not shown) (step S47).

Here, in a state where the vehicle speed is 30 [km / h] or less, the vehicle speed is 40 [km before reaching 200 seconds.
/ H] or more, the determination unit 13 initializes addition of the current addition data.

When the presentation of the traffic information is completed, the usual song "2" is presented (step S48). And time t
When the vehicle enters the intersection at 9, the calculation unit 12 generates scene information indicating that the vehicle is traveling at the intersection, and the determination unit 1
Enter with 3. In response to this, the determination unit 13 performs the determination process of step S15, and the conditional statement number “2
7 ”is detected and the determination result is output to the presentation processing unit 14.
In response to this, the presentation processing unit 14 controls the sound output unit 6 that executes the mute for the presented normal music piece "2" (step S49).

Then, when the vehicle exits the intersection, the scene information indicating that the vehicle is traveling normally is generated by the calculation unit 12 and input by the determination unit 13. Accordingly, the determination unit 1
3, the conditional sentence number “9” is detected again, and the determination result is output to the presentation processing unit 14, and the presentation processing unit 14 releases the mute and presents the normal music “2”. Is controlled (step S50).

At the next time t10, scene information based on the fact that the vehicle has determined that the vehicle has not arrived at the destination is generated by the calculation unit 12 from the current position information and the route setting information by the navigation system (not shown). Enter with 13. In response to this, the determination unit 13 detects the scene before the arrival of the conditional sentence number "6", and then presents the pre-arrival narrative "1" of the conditional sentence number "23" (step S51). Then, the musical piece “1” before arrival of the conditional sentence number “24” is presented (step S52). When the presentation of the piece of music “1” before arrival is completed, the determination unit 13 then detects the conditional sentence number “25” and outputs the determination result to the presentation processing unit 14. In response to this, the presentation processing unit 14 presents the narration "2" before arrival (step S53).
