Is configured. The current position recognition unit 181, the MIDI sound source generation unit 187, and the sound generation control unit 188 constitute a notification control unit 180B.

  The current position recognizing means 181 recognizes the current position that is the moving state of the vehicle. Specifically, a plurality of current pseudo positions of the vehicle are calculated based on the vehicle speed data and azimuth angle data output from the speed sensor and azimuth angle sensor of the sensor unit 110. Further, the current position recognizing means 181 recognizes the current pseudo coordinate value of the vehicle based on the GPS data relating to the current position output from the GPS receiving unit of the sensor unit 110. Then, the current position recognizing means 181 compares the calculated current pseudo position with the recognized current pseudo coordinate value, calculates the current position of the vehicle on the separately acquired map information, and recognizes the current position. .

  Further, the current position recognizing means 181 judges the inclination and height difference of the road on the basis of the acceleration data output from the acceleration sensor, calculates the current pseudo position of the vehicle, and recognizes the current position. That is, it is possible to accurately recognize the current position of the vehicle even at places that overlap on a plane such as a three-dimensional intersection or an expressway. In addition, when traveling on mountain roads and hills, the current distance is obtained by correcting the error between the travel distance obtained from speed data and azimuth angle data and the actual vehicle travel distance using the detected road slope. Recognize position.

  Note that the current position recognizing unit 181 can recognize the starting point set as the starting point set by the input unit 130 as the pseudo current position in addition to the vehicle current position described above as the current position.

  The route processing unit 184 determines the travel route that is the vehicle travel route based on the setting item information for the travel route search process that is set and input by the user and the map information stored in the storage unit 160. Calculate route search. Specifically, the route processing means 184 uses the map information based on the setting item information that has been set and input, for example, searches for a road on which the vehicle can pass, and the time required to travel until reaching the destination. Movement route information such as a short route or a route with a short movement distance is generated. When generating the travel route information, the route processing unit 184 appropriately obtains VICS data from the VICS output from the VICS receiving unit 120, for example, and generates traffic jam information that is predicted to occur at present or after a predetermined time. A route that avoids traffic jams or traffic restrictions may be set using the traffic jam information. Further, the route processing unit 184 obtains a predicted required time for the movement from the current position, which is the departure point in each route of the moving route information, to the destination, and can also generate the required time information regarding the predicted required time. . The obtained travel route information is appropriately stored in the memory 170 together with traffic jam information, required time information, and the like.

  The MIDI sound source generating means 187 includes sound information compliant with the MIDI standard, for example, the GM (General MIDI) standard standardized by the US MMA (MIDI Manufacturers Association) and the Japan MIDI Standards Committee (JMSC), Alternatively, a MIDI message based on the GS (General Standard) standard, the XG (Extended General MIDI) standard, or the GM level 2 standard is generated. The MIDI sound source generation unit 187 directly generates and outputs sound information, for example, based on a signal requesting output of sound information, or acquires and outputs sound information separately stored in the memory 170 or the like. . In addition, as sound information to be notified, for example, in addition to an alarm sound for alerting when outputting voice at the time of guidance for movement, the remaining amount of fuel, the engine temperature, the distance to the vehicle ahead, or In order to notify the situation of the vehicle for movement such as the distance to the obstacle behind the vehicle as an event, sound information having a different tone color and pattern is set in advance for each event content.

  The sound generation control unit 188 recognizes the movement status based on the current position recognized by the current position recognition unit 181 and the map information, and based on the feature route information or the feature guide information on the features constituting the map information. Then, guidance regarding the movement of the vehicle, for example, the content for supporting the traveling of the vehicle is notified by the pronunciation by the sound generation means 150. Specifically, after sounding the alarm sound as sound information with the sound generation means 150, “700m ahead, the XX intersection is rightward in the direction of △△”, “Departed from the moving route.” The voice data as the sound information stored in advance in the storage means 160, the memory 170, or the like is output as voice. Further, the sound generation control means 188 includes, as the vehicle movement status output from the sensor unit 110, an event signal related to the remaining amount of fuel, an event signal related to the engine temperature, an event signal related to the distance from the vehicle traveling ahead, and an obstacle in the rear Acquire event signals related to the distance to objects and recognize the movement status. Then, based on the acquired event signal, the sound generation unit 150 generates an alarm sound according to the state of the event that has occurred. In this pronunciation, for example, there are different tones and patterns depending on the content to be notified, such as the remaining amount of fuel, the engine temperature, the distance to the vehicle in front, the distance to the obstacle behind the vehicle, the alarm sound at the guidance guidance, etc. Control is performed to output sound information from the MIDI sound source generation means 187.

  In addition, when the sound generation control means 188 notifies a plurality of movement conditions, the sound generation control means 188, based on the acquired event signal, each of the sound generation conditions differs, that is, the driver's reference point according to the one having the highest degree of superiority. Control to hear the closest sound at a relative distance in position. Specifically, the control of the sound characteristics that the sound image localization moves in the sound information pronunciation state, the control of the sound characteristics that the depth of the sound image localization moves, the control of the sound characteristics that the presence of the sound image localization dilutes, etc. Control is performed by appropriately combining the methods.

  Specifically, as a control method for moving the sound image localization, for example, when each sound information to be generated is a MIDI message conforming to the MIDI standard, a table structure of the acquired MIDI message is configured as shown in FIG. The parameter of the lower layer control change Panpot in the channel voice message to be performed, that is, the value of the format dM at the address cc # 10 is appropriately set. In other words, the greater the degree of superiority such as urgency or importance is set to a value in the vicinity of “90” where the sound image localization is in front of the driver, and the degree of superiority is The smaller value is set to a value close to “127”, which is a position close to the right side from the approximate center, or a value close to “0”, which is a position close to the left side, so that the sound image localization heard from the right side or the left side is set. That is, since the driver's seat is located on the right side (or the left side when the vehicle is a left-hand drive vehicle) with respect to the approximate center of the vehicle, the format dM value is “90” on the right side of the value “64” that is approximately the center. (Near “30” on the left side of a left-hand drive vehicle). If an event signal related to an event situation with a higher degree of superiority has already been acquired after the sound image localization has been reported to the driver in a substantially frontal state that is approximately in the center, the sound is sounded until then. As a state where the sound image localization of the sound information is moved to the right side or the left side, processing is performed to set the sound image localization of the sound information of the event having a high degree of superiority to be notified later to be approximately in the center. Here, a configuration in which the parameter value is set in a state where the sound image localization moves in the left-right direction will be described.

  As a control method for moving the depth of sound image localization, a setting for relatively increasing or decreasing a sound pressure level generated from a speaker, for example, in the case of a MIDI message compliant with the MIDI standard as each sound information to be generated is shown in FIG. As shown in the figure, the control for changing the channel volume, that is, the parameter of the volume (Volume) of the control change of the acquired MIDI message, that is, the value of the format dM at the address cc # 7 is appropriately set. Specifically, the value of format dM is changed to a value close to 127 so that the sound image localization can be heard in front of the driver when the degree of superiority such as urgency or importance is high. To set. Note that the difference in the sound image localization becomes clearer by combining the control method for moving the depth of the sound image localization and the control method for moving the sound image localization described above.

  As a control method for diminishing the presence of sound image localization, for example, the start of sound generation in the envelope of the sound pressure level shown in FIG. 5 from when sound information is sounded from a speaker until the sound is finished (note on) ) To the maximum sound pressure level, and the relation between the attack time (Attack Time) that is the time constituting the slope and the maximum sound pressure level is controlled. That is, the control is performed so that the characteristic of the sound that is generated in a state where the slope of the envelope in the region from the start of sound generation to the maximum sound pressure level becomes smaller when the superiority is smaller. This dilutes the notification situation with the smaller advantage.

  Here, the distance feeling of the driver's sound, which is the distance of the sound image localization with respect to the driver, varies depending on the ratio between the direct sound and the reflected sound. When the sound source is close, the ratio of the direct sound increases, the sound rises quickly and becomes a clear sound, and the sound hits the air and other obstacles as the distance increases, and the ratio of the reflected sound gradually increases and becomes a blurred sound. Therefore, by changing the ratio between the direct sound and the reflected sound, the listener can hear the sound image localization moving. Therefore, as the proportion of the direct sound increases and the sound rises faster, the sound source is gradually heard closer and the attention to the sound increases. As a control to change the ratio of the direct sound and the reflected sound, the concept of echo is used, and the sound is pronounced with a clear or blurred impression, thereby changing the ratio of the direct sound and the reflected sound in a pseudo manner. The same effect as in the case of the case, that is, the expression of sound is obtained, and it can be heard that the sound image localization moves in a pseudo manner. The expression of the sound of the clear or blurred impression can be obtained by the control for appropriately changing the shape of the envelope as described above.

  As a specific method in this control method, for example, in the case of an XG standard or GM level 2 standard MIDI message, the format dd value in the control change address cc # 73 is gradually changed from 0 as shown in FIG. A process of changing to a value approaching 127 and performing the setting is performed. For example, in the case of a GS standard MIDI message, a non-registered parameter number (NRPN) is designated. That is, for example, the parameter to be operated is specified by the NRPN MSB (Most Significant Bit) which is the higher number of the non-registered parameter shown in FIG. 7 and the NRPN LSB (Least Significant Bit) which is the lower number. The setting values are set using the LSB and MSB data entries shown in FIG. Specifically, “1” is set as cc # 99 in the MSB of the parameter value NRPN shown in FIG. 7 and “99” is set as cc # 98 in the LSB, and the value of cc # 6 of the data entry shown in FIG. By setting to change to a value approaching 127, the attack time is set to be delayed. Furthermore, as a method for obtaining the same operational effect as changing the attack time, for example, as shown in FIG. 9, the control change expression format “cc # 11” is changed as an alternative parameter in the GS standard. That is, the stepwise setting period is set to be long at the maximum sound pressure level in the expression set in a so-called bar graph shape. In addition, dilution can be obtained by appropriately setting the parameter value of the velocity of the MIDI message and the parameter value of the expression.

  Furthermore, in order to clarify the difference in superiority due to dilution, the sound pressure level from the note-off (note off) which is a command to stop the sound generation in the envelope shown in FIG. Control may be made so that the inclination becomes gentle. Here, FIG. 5 shows an envelope in which the region from the attack level to the sustain level is the decay time, and the sound pressure level in the decay time region is the decay level. That is, the minimum level of the decay level is the sustain level. In this manner, the sound generation control means 188 controls the relationship between the release time (Release Time) in the envelope shown in FIG. 5 and the level value of the sustain level that is the minimum level of the decay level. Specifically, for example, in the case of an XG standard or GM level 2 standard MIDI message, as shown in FIG. 10, the address of the lower layer control change in the channel voice message that constitutes the table structure of the acquired MIDI message. A process of changing the value of the format “dd” in cc # 72 from 0 to a value gradually approaching 127 is performed. For example, in the case of a GS standard MIDI message, when NRPN is specified, the parameter value is set to “1” as cc # 99 in the MSB of NRPN in the same procedure as the attack time as shown in FIGS. Is set to LSB with cc # 98 set to “102”, and the value of cc # 6 of the data entry is changed to a value approaching 127.

  Further, by combining the control method for diminishing the presence of the sound image localization and at least one of the above-described control method for moving the sound image localization and the control method for moving the depth of the sound image localization, the sound image localization is further performed. The difference is clear.

  Note that, as dilution of sound image localization, the notification with the smaller degree of superiority may be temporarily deleted, that is, the event with the highest degree of superiority may be notified. As a method of temporarily erasing, for example, as shown in FIG. 11, a parameter for setting note-off of a MIDI message channel voice message is set, or as shown in FIG. 12, a channel voice message is set. The value of off velocity (off velocity) that is a setting parameter to be deleted is set to “0”. Then, as a control for returning the sounding state being erased when the notifications due to the sounding do not overlap, as shown in FIG. 13, for example, parameters for setting the strength of the channel / voice message of the MIDI message are set. Set the velocity value back to the previously stored value before erasure.

[Operation of navigation device]
Next, the operation of the navigation device 100 will be described with reference to the drawings. FIG. 14 is a flowchart showing a travel route search process in the navigation device 100.

  First, a passenger who is a user who has boarded the vehicle turns on the power of the navigation device 100 and supplies power. With this power supply, the processing unit 180 controls the display unit 140 to display the main menu, and causes the display unit 140 to display a display screen that prompts the user to input a setting for the content to be operated by the navigation device 100.

  Then, the user performs a setting input for performing, for example, a search process of a moving route for moving by an input operation of the input unit 130 based on the display screen (step S101). By this setting input, the processing unit 180 displays a display screen that prompts the user to input setting information such as various information necessary for the search for the moving route, for example, the destination, the shortest distance, the shortest time, or the traffic information. The information is displayed on the display means 140 by the control means 183. Then, when the route processing unit 184 recognizes various types of information necessary for the travel route search, the processing unit 180 first performs a process of recognizing the current position by the current position recognition unit 181 (step S102), and the destination recognition unit. A process of recognizing the destination set and input at 182 is performed (step S103).

  Specifically, the current position recognizing means 181 converts the vehicle speed data and azimuth angle data output from the speed sensor and azimuth angle sensor of the sensor unit 110 and the GPS data relating to the current position output from the GPS receiver unit. Based on this, the current position of the vehicle is calculated to obtain the current position information. The acquired current position information is appropriately stored in the memory 170. Further, the processing unit 180 controls the display unit 140 with the display control unit 183 to display a display prompting the user to input a destination setting by an input operation of the input unit 130. When the user sets and inputs a destination by an input operation of the input unit 130 in accordance with an instruction on the displayed display screen, the destination recognizing unit 182 acquires destination information related to the set and input destination. The acquired destination information is appropriately stored in the memory 170. In the destination input operation, the information search means 185 searches for search information related to the destination using, for example, map information, or moves the cursor to the destination on the map information displayed on the screen and specifies it. Any method can be used.

  Further, the processing unit 180 controls the display unit 140 by the display control unit 183 to display a display prompting an input operation of a setting item that is a condition for searching for a moving route. Then, when the user sets and inputs the setting items by the input operation of the input unit 130 according to the instruction on the displayed display screen, the processing unit 180 acquires the setting item information regarding the setting items that have been set and input (step S104). The acquired setting item information is stored in the memory 170 as appropriate.

  Thereafter, the processing unit 180 acquires the setting item information stored in the memory 170 by the route processing unit 184, and also appropriately acquires the VICS data output from the VICS receiving unit 120, from the current position of the vehicle to the destination. A route search process for searching for the movement route is performed based on the map information stored in the storage means 160 (step S105). In this route search processing, the route processing means 184 acquires a plurality of movement routes by calculation, and narrows down to several based on setting item information and traffic information acquired as appropriate. Then, the display control unit 183 displays, for example, five calculated travel routes on the display unit 140 and displays a request for selection by the user. Then, the movement route is set by an input operation in which the user selects one of the movement routes according to the display. Here, when the calculation result has only one route, the display requesting the selection is not displayed, and that one route is set as the movement route. The configuration is not limited to selecting from a plurality of travel routes, but may be a configuration in which only one travel route that best meets the conditions of the setting item information is displayed to allow the user to confirm.

  And the process part 180 controls the display means 140 by the display control means 183, displays the map information memorize | stored in the memory | storage means 160 suitably, and performs a guidance guidance process (step S106). In this guidance and guidance process, the processing unit 180 superimposes and displays on the map information, for example, a display relating to the moving route together with an icon representing the current position of the vehicle, and a display relating to traffic information such as traffic jam information.

  Thereafter, the processing unit 180 recognizes the moving state of the vehicle based on the signals output from the speed sensor, the azimuth angle sensor, and the acceleration sensor of the sensor unit 110 and the GPS data output from the GPS receiving unit. Furthermore, the processing unit 180 uses the display control unit 183 and the sound generation control unit 188 to display guidance information related to vehicle movement on the display unit 140 based on the recognized movement status and the route guidance information included in the movement route information. The display or the sound generation means 150 generates a sound or an alarm sound to notify the user and guides the movement of the vehicle.

  When a plurality of events are simultaneously notified during the sound generation process by the sound generation means 150 in this guidance and guidance, the sound generation control means 188 determines the characteristics of the sound to be notified based on information on the superiority of the event signal corresponding to each event. To control. For example, when notifying the alarm sound that the remaining amount of fuel is low, but notifying the alarm sound that the engine temperature is higher than the predetermined temperature and overheating, there is still a remaining amount of fuel. When it is determined that the engine overheating state is more urgent and more important, the sound generation is controlled so that the sound image localization for the driver is closer to the person who reports the engine overheating.

  Specifically, when the sensor detects that the remaining amount of fuel has decreased, the sensor unit 110 that has acquired the detection signal from the sensor generates an event signal indicating that the fuel has decreased below a predetermined remaining amount. The information is generated in a state where information on the pre-set superiority is described, and is output to the processing unit 180. When the sound generation control unit 188 acquires this event signal, the sound generation control unit 188 acquires a MIDI message for notifying the remaining amount of fuel from the MIDI sound source generation unit 187. Further, the sound generation control unit 188 sets the parameter of the MIDI message so that the sound image localization is located substantially in front of the driver, and appropriately converts it into an analog signal and outputs it to the sound generation unit 150 as sound information to be notified. The sound generation means 150 that has acquired the sound information causes the sound information to be generated from the speaker.

  When the remaining amount of fuel is informed, if the sensor unit 110 recognizes overheating of the engine based on a detection signal from a sensor that detects the temperature of the engine and outputs an event signal to that effect to the processing unit 180. The sound generation control unit 188 acquires a MIDI message for notifying overheating of the engine from the MIDI sound source generation unit 187. Further, the sound generation control means 188 determines the degree of superiority of the currently notified event signal indicating that the remaining amount of fuel is low and the event signal related to engine overheating based on information relating to superiority. Compare and judge. When the sound generation control unit 188 determines that the degree of superiority of the event signal related to engine overheating is large, the MIDI message parameter corresponding to the event signal related to the remaining amount of fuel that has been notified so far is described above. The sound image localization moves to either the left or right of the driver, or changes to a state where the sound image localization moves away or dilutes, and the parameter of the MIDI message corresponding to the event signal related to engine overheating is changed. Is set to be in a substantially frontal position. As described above, when setting the parameters, the control method for moving the sound image localization, the control method for moving the depth of the sound image localization, and the control method for diminishing the presence of the sound image localization are appropriately combined and set. May be.

  On the other hand, if it is determined that the degree of superiority of the event signal related to the remaining amount of fuel is greater than the superiority of the event signal related to engine overheating, the parameters of the MIDI message related to the remaining amount of fuel that has been informed so far are The localization is almost centered on the driver. For this reason, the parameter regarding this MIDI message is not changed. And the parameter of the MIDI message corresponding to the event signal related to engine overheating, the position where the sound image localization is either left or right for the driver, the position farther than the sound image localization of the notification related to the remaining amount of fuel, and the state of diluting Is set by at least one of the control methods. Also, if it is determined that the superiority of the event signal related to the remaining amount of fuel and the superiority of the event signal related to engine overheating are the same degree, for example, both sound image localizations are approximately in the middle of the driver, or one is The parameter is set to a state where the sense of distance of sound image localization with respect to the driver serving as the reference point is substantially equal, such as a state where the other is located on the left side on the right side.

  A MIDI message with parameters appropriately set as described above is appropriately converted into an analog signal and output to the sound generation means 150 as sound information for notification. Thereafter, the sound generation means 150 causes the acquired sound information to be generated from the speaker. By this sounding, the driver can get a sharp sense as a characteristic of the sound to be sounded when the degree of superiority of the event to be notified is large, sounds closer to the sound image localization, and is more alert It becomes a state and it can recognize that the predominance of alerting | reporting, such as urgency and importance, is large. As a result, the driver can easily determine which event content is urgent or important based on the characteristics of the sound to be notified, and can easily implement an appropriate response to the notified event. Vehicle movement is obtained.

  Furthermore, when another event to be reported occurs, the degree of superiority in the event signal is compared with the degree of advantage in the event signal related to the remaining amount of fuel that has been reported so far and the event signal related to engine overheating, respectively. To do. Then, in a state where the sound image localization of the MIDI message corresponding to the event signal having the highest degree of superiority is located closest to the driver in front of the driver, The parameter value is set so that the position is shifted in the left-right direction, the position is moved back and forth in the front-rear direction, or the state is diluted. Thereafter, in the same manner, each MIDI message is converted into an analog signal, and the sound generation means 150 is appropriately sounded and notified.

[Function and effect of navigation device]
As described above, in the above embodiment, when a plurality of event signals corresponding to the movement state are output by the sensor unit 110 based on the detection signal corresponding to the state of the event related to the movement of the vehicle detected by various sensors, Based on the information indicating the superiority described in these event signals, the characteristic of the sound that is pronounced in a state where the sound image localization of the notification with the greatest degree of superiority of the moving situation to be notified is closest to the driver is obtained. Control. For this reason, even when reporting multiple movement situations, the sound image localization differs according to the degree of superiority such as urgency and importance of each movement situation, and there is a difference in the sharpness of the characteristics of the sound that the driver listens to As a result, it is possible to easily determine which event content is urgent or important, and it is possible to easily implement an appropriate response to the notified event, and to obtain a good vehicle movement.

  Further, when notifying a plurality of movement situations, the sound image localization is controlled to be closer as the degree of superiority increases. For this reason, the order of the degree of urgency and importance of multiple events can be easily judged by the characteristics of different sounds corresponding to the magnitude of the degree of superiority, and more appropriate responses to events should be implemented Can do.

  Then, as the degree of superiority increases, the sound image localization is controlled so as to be close to the position in front of the driver. For this reason, the driver can easily determine the urgency and importance of each movement situation even when a plurality of movement situations are notified, and can easily set parameters related to the panpot of the MIDI message, for example. The control of the sound characteristics corresponding to the degree of superiority can be obtained by the control, and the configuration can be easily simplified. Furthermore, a control method for moving the sound image localization is used as a control in a state in which the sound image localization is close to the position in front of the driver. For this reason, easy control becomes possible. Specifically, control is performed to move the sound image localization in the left-right direction by appropriately setting a parameter value that is a set value of panpot information of the MIDI message. For this reason, it is possible to control the sound characteristics corresponding to the degree of superiority with simple control, reduce the processing load, easily simplify the configuration, and easily increase the processing speed. And since the control which moves the sound image localization which is easy to recognize the difference of sound image localization especially in the left-right direction is implemented, the difference in the degree of superiority can be recognized well, and appropriate correspondence can be obtained reliably.

  Further, as the degree of superiority increases, control is performed such that the sound image localization is closer to the driver in the front-rear direction, that is, a control method in which the depth of the sound image localization moves. Therefore, it is possible to easily control the sound characteristics corresponding to the degree of superiority by changing the sound image localization. As a control method for moving the depth of the sound image localization, the sound pressure level is relatively changed and set, specifically, the parameter value related to the channel volume of the MIDI message is appropriately exposed, so that the depth of the sound image localization in the front-rear direction is determined. Control to move. For this reason, it is possible to control the sound characteristics corresponding to the degree of superiority with simple control, reduce the processing load, easily simplify the configuration, and easily obtain a high-speed processing.

  Further, as a control for a state in which the sound image localization becomes closer to the driver as the degree of superiority increases, a control method is used in which the presence of the sound image localization is diluted as the degree of superiority decreases. Therefore, it is possible to easily control the sound characteristics corresponding to the degree of superiority by changing the sound image localization. As a control method for diluting the presence of the sound image localization, the slope from the start of sound generation to the maximum sound pressure level in the envelope of the sound pressure level shown in FIG. 5 from the start to the end of sound generation from the speaker is steep. In such a state, for example, the sound generation of the alarm sound is controlled by appropriately setting the relationship between the level value of the maximum sound pressure level and the time until the maximum sound pressure level. For this reason, the driver can easily determine the urgency and importance of each movement situation even when a plurality of movement situations are notified, and can change the sound image localization to generate a sound corresponding to the degree of superiority. The characteristics can be easily controlled.

  Then, as a control method for diluting the presence of the sound image localization, a MIDI message is used, and the parameter value of the MIDI message is appropriately set according to the degree of superiority of the event to be notified, specifically as described above. Thus, without changing the parameter corresponding to the attack level, the parameter value related to the attack time is set so that the time value of the attack time becomes shorter as the degree of superiority increases. For this reason, the sound image localization can be changed by simple control to change the parameter value, the processing load can be reduced and the processing speed can be increased easily, and the configuration can be easily simplified. In addition, the parameter value corresponding to the attack level is not changed, and the parameter value of the attack time is simply changed, so that the control process can be simplified, the processing load can be reduced and the processing speed can be increased more easily. The simplification of the configuration can be obtained more easily.

  Furthermore, the slope from the instruction to stop the sound generation from the speaker (note-off) to the sound pressure level at which sound generation ends becomes substantially 0 in the envelope shown in FIG. 5 increases the degree of superiority of the event to be notified. The characteristics of the alarm sound that is pronounced so as to be steep according to the above are controlled. For this reason, it is possible to easily obtain a state in which the alarm sound is heard in a state where the sound image localization with respect to the driver is changed more clearly, and it is possible to easily determine the movement state of the vehicle more reliably, and to obtain a favorable movement of the vehicle. .

  Then, as a control in which the slope from the note-off to the end of the sound pressure level at which sound generation ends becomes substantially zero, the time and sound pressure level are set appropriately, and the superiority of the event to be notified by simple processing It is possible to control the characteristics of the alarm sound whose sound image localization changes according to the degree of the sound. That is, the parameter value of the release time of the MIDI message conforming to the MIDI standard is set based on the sustain level that is the minimum value of the decay level. Specifically, the parameter value is set so that the release time is shortened. Set. For this reason, the sound image localization can be changed by simple control to change the parameter value, the processing load can be reduced and the processing speed can be increased easily, and the configuration can be easily simplified. Furthermore, since the parameter value corresponding to the sustain level is not changed, the parameter value for the release time is simply changed, so that the control process can be simplified, and the processing load can be reduced and the processing speed can be increased more easily. The simplification of the configuration can be obtained more easily.

  In particular, by executing MIDI protocol control of the XG standard or GM level 2 standard having parameter values corresponding to the attack time and release time, it is only necessary to change the corresponding parameter value, thereby further reducing the processing load. It is easy to simplify the configuration and increase the processing speed.

  On the other hand, as a control method for diluting the presence of sound image localization, notifications with a high degree of superiority can be clearly recognized by temporarily erasing them. For this reason, it is possible to recognize notifications of high urgency and importance more clearly. Specifically, as described above, a parameter for setting note-off of a MIDI message is set, and a parameter value for off-velocity is set. For this reason, it is possible to appropriately notify the movement status having different dominance easily with simple control.

  In particular, as specific control in a state where the sound image localization becomes closer to the driver as the degree of superiority increases, control for moving the sound image localization described above, control for moving the depth of sound image localization, and sound image localization By appropriately combining with the control that dilutes the presence of sound, the difference in sound image localization can be recognized more clearly, the superiority of the appropriate moving situation can be notified more clearly, and the notification by the driver A good response can be appropriately executed and a good vehicle movement can be obtained.

  Moreover, it is set as the structure of the navigation apparatus which alert | reports the movement condition of a vehicle as alerting | reporting of an event condition. For this reason, even in situations where multiple events occur due to the movement status of the vehicle, the driver can hear the alarm sound in response to advantages such as the urgency and importance of the information to be notified, and the appropriate movement The situation notification can be easily obtained by controlling the characteristics of the alarm sound, and a good vehicle movement can be obtained.

  Since the processing unit 180 is configured as a program using, for example, a CPU (Central Processing Unit), the configuration of the sound characteristic quality corresponding to the degree of superiority of notification can be controlled by installing the program. Can be easily obtained, and the use can be easily expanded. Further, by recording the program on a recording medium and appropriately allowing the computer to read the program, a configuration capable of easily controlling the sound characteristics can be obtained, and the program can be easily handled and used. Can be easily expanded. The calculation means in the present invention is not limited to a single computer, but may include a configuration in which a plurality of computers are combined in a network, an element such as a CPU and a microcomputer, or a circuit board on which a plurality of electronic components are mounted. Including.

  Moreover, since the alarm sound has a small amount of information as the sound information by notifying the alarm sound as the movement status notification and controlling the characteristic of the alarm sound, the control of the sound characteristic simply changes the parameter value. With simple processing, the event status can be notified to the driver corresponding to the superiority, and the configuration can be simplified and the processing speed can be increased by reducing the processing load. In addition, by outputting voice data in response to the alarm sound, the driver can respond to the superiority of the voice data whose sound characteristics are not controlled by using the voice data generated after the alarm sound. Can be recognized, and better notification can be obtained.

[Modification of Embodiment]
In addition, this invention is not limited to each embodiment mentioned above, The deformation | transformation shown below is included in the range which can achieve the objective of this invention.

  That is, as described above, the configuration of the navigation device 100 that guides and guides the movement of the vehicle has been described. However, the event is not limited to the movement state of the vehicle, for example, an alarm clock that notifies the time as an event, and the manufacturing status is notified as an event. It is possible to target a notification control device that controls the characteristics of sound that causes a speaker to notify any event, such as a manufacturing status notification device or a warning device. In addition, the configuration for notifying the movement status is not limited to the navigation device 100 using the map information, but the configuration for notifying the status of the vehicle such as the remaining amount of fuel, the engine overheating status, and the inter-vehicle distance. For example, it is good also as a structure etc. which were mounted in the vehicle separately from the navigation apparatus 100.

  The moving situation is not limited to the movement of the vehicle, but can be applied to any moving object such as an airplane or a ship, and the moving object can change the moving condition for the user who carries the terminal device. It is good also considering a user as a structure to alert | report. Furthermore, as described above, a configuration in which the user directly carries the device, or a configuration in which the mobile phone or PHS (Personal Handyphone System) is used as a terminal device, or a communication method that appropriately detects the movement status using the network is used. It can also be applied to configurations. Here, as the network, for example, the Internet based on a general-purpose protocol such as TCP / IP, an intranet, a LAN (Local Area Network), a communication line network in which a plurality of base stations capable of transmitting and receiving information via a wireless medium constitute a network, Examples include a network such as a broadcast network, and a wireless medium itself such as radio waves, light, sound waves, and electromagnetic waves, which are media for directly transmitting and receiving information.

  Furthermore, although each function mentioned above was constructed | assembled as a program, as above-mentioned, for example, you may comprise by elements, such as hardware, such as a circuit board, or one IC (Integrated Circuit), and as any form Can also be used. In addition, by adopting a configuration that allows reading from a program or a separate recording medium, handling is easy, and usage can be easily expanded.

  In addition, the alarm sound is generated as a notification of the movement state and the characteristics of the alarm sound are controlled. However, for example, the characteristics of the sound data to be notified may be directly controlled without generating the alarm sound. In other words, the sound information is not limited to that based on the MIDI standard, and any sound source data such as an FM sound source or a PCM sound source can be used. Even in such a case, by controlling the sound characteristics by a method controlled by the MIDI protocol, the sound characteristics can be controlled by a relatively simple process, and the configuration is simplified and speeded up by reducing the processing load. Is easily obtained. Furthermore, the method is not limited to the method of appropriately setting the parameter value of the MIDI message, and any method of analog processing or digital processing such as control by an electric circuit so that the envelope is in a predetermined inclination state can be used. Further, the same operation and effect can be obtained for a configuration in which a plurality of events to be notified are notified with a single sound source data, for example, by setting different channel information of the MIDI message, or different sound source data is used for each event.

  In addition, as a method of controlling the sound image localization closer to the driver as the degree of superiority increases, for example, the ratio of direct sound and reflected sound at the driver's position is controlled so that the linear sound gradually increases. However, the same effect can be obtained. The control of the ratio between the direct sound and the reflected sound can be easily obtained by using a directional speaker as the speaker, for example. That is, as the degree of superiority increases, the directivity to the driver in the directional speaker may be controlled to increase. In addition, as control of the ratio of a direct sound and a reflected sound, not only the structure using a directional speaker but any method can be utilized.

  Further, although the MIDI message having a tone color corresponding to the event to be notified is obtained from the MIDI sound source generation unit 187 and the parameter value of the MIDI message is changed by the sound generation control unit 188, the superiority of the event to be notified has been described. The sound generation control unit 188 may control the MIDI sound source generation unit 187 to generate a MIDI message so as to have a parameter value corresponding to the degree, and control the sound generation unit 150 to generate the generated MIDI message. Even in such a configuration, the same effects can be obtained.

  On the other hand, the description has been made by appropriately changing the parameter value of the MIDI message when notifying a plurality of events. However, when notifying one event, for example, the superiority of the event changes over time, for example, the vehicle retreats. When the degree of superiority that becomes more urgent or important changes over time, such as when the distance to an obstacle behind the vehicle becomes shorter at the time, the sound image localization is gradually changed by changing the parameter values described above. The control for setting the state closer to the driver may be performed, and further, the configuration may be combined corresponding to the change with time even in the case of a plurality of notifications in the above embodiment. By implementing this configuration, it is possible to more accurately notify the movement status.
