Description

The present invention relates to a device used in a mobile body and a program for operating the device used in the mobile body.

In recent years, drive recorders have been installed in moving bodies such as automobiles for the purpose of analyzing the situation when an accident occurs.

A drive recorder is, for example, a camera that captures images of the surroundings of a vehicle, an acceleration sensor that detects abnormalities such as sudden braking or sudden steering in order to avoid collisions and accidents, etc., and images captured by the camera. It is equipped with a storage medium that stores the image data.

The camera constantly captures video data of the surrounding area while the vehicle is running. In addition, the output from the acceleration sensor is monitored, and if the acceleration exceeds a predetermined threshold, it is assumed that an abnormality such as sudden braking or sudden steering has occurred in order to avoid a collision or accident. Image data for a predetermined period of time before and after is stored in a storage medium. Video data that is constantly captured is overwritten as time passes, but image data that is saved on a storage medium when acceleration exceeds a predetermined threshold is not overwritten and can be played back at a later date. Become.

This allows the user to check the surroundings of the vehicle when an abnormality such as sudden braking or sudden steering occurs in order to avoid a collision or an accident. An example of such a drive recorder is described in Patent Document 1, for example.

It is also conceivable to save not only image data but also points where the acceleration exceeds a predetermined threshold value in a storage medium. It is also conceivable to superimpose and display information representing a point where the acceleration exceeds a predetermined threshold value on a map displayed by a car navigation device that provides driving guidance to a user using a mobile object.

Here, as a premise for doing this, the basic functions of the car navigation device will be explained.

An example of a car navigation device is described in, for example, Patent Document 2. The car navigation device described in Patent Document 2 includes a position detection unit that detects the current position of the own vehicle by performing positioning using GPS (Global Positioning System), a storage unit that stores road type information, etc. and a display section that displays images.

The car navigation device described in Patent Document 1 creates operation guidance information based on the destination position, the current position of the host vehicle, road type information, etc., and uses the created operation guidance information. Displayed on the display overlapping the map information.

By displaying this operation guidance information on a map, including icons representing points where the acceleration described above exceeds a predetermined threshold, the user can identify points where acceleration exceeded a predetermined threshold in the past. It becomes possible to easily understand where it is.

Japanese Patent Application Publication No. 2013-235395 Japanese Patent Application Publication No. 2013-160679

As described above, by using the functions of the drive recorder, it is possible to store and reproduce video data when an accident or the like occurs, or to memorize the location where an accident or the like occurs. Furthermore, if the functions of a car navigation device are also utilized, icons or the like representing the location where an accident or the like has occurred can be displayed on the map.

However, the method of detecting the occurrence of an accident using measurement information such as acceleration cannot completely eliminate the possibility of erroneously detecting that an accident has occurred even though no accident has occurred. I can't. In other words, if acceleration exceeds a predetermined threshold, it can only be assumed that an accident has probably occurred, and even if acceleration exceeds a predetermined threshold, an accident has not actually occurred. It is also possible that it is not.

Here, a case in which such erroneous detection occurs will be explained using a specific example.

For example, suppose there is a point on the road where there is a step with a certain level of drop. Then, each time the moving body equipped with the drive recorder passes a step at the point, it receives a certain impact depending on the head of the step, and accordingly, the acceleration exceeds the threshold every time it passes. As a result, it is assumed that an accident has occurred at that point each time the point is passed.

However, the event of simply driving over a point with a step is not an event that should be detected in connection with the function of the drive recorder. Events that should normally be detected in connection with the drive recorder's functions include, for example, accidents caused by contact with other vehicles, and inappropriate dangers such as sudden braking or sharp turns to avoid accidents. This is an event in which driving was performed.

In other words, in light of the original purpose of recording video data using the drive recorder function, it is inappropriate to assume that an accident has occurred when driving over a point with a step. It can be said that it is false detection to assume that an accident or the like has occurred in this way.

Further, when such a false detection is made, many problems occur in connection with the false detection, and this point will be explained below.

Naturally, since the capacity of a storage medium is limited, there is also an upper limit to the number of video data that can be stored. Nevertheless, if unnecessary video data is saved due to erroneous detection, a problem arises in that the storage capacity of the storage medium is wasted. In addition, related to this, unnecessary video data can cause the storage medium to run out of free space, resulting in the problem of not being able to store the video data at the time of the accident even though an accident has actually occurred, and the problem of correct detection. There also arises a problem that the video data stored based on the data is overwritten and erased.

Furthermore, as described above, when displaying an icon or the like representing a point where an accident or the like has occurred on a map, an icon representing a point where an erroneous detection has occurred will also be displayed. This also causes a problem in that it becomes difficult to see the icons representing the actual locations of accidents and the like that should be displayed, as well as the map itself.

Therefore, it is an object of the present invention to provide a device and a program that can prevent the occurrence of an accident from being performed even though the occurrence of the accident has been erroneously detected. purpose.

(1) A device that performs control to store first information when a first condition is satisfied, wherein the first information is stored due to an event that does not require storage of the first information. An apparatus characterized in that, at a certified point where a condition is met, no control is performed to store the first information even if the first condition is met again.

In this way, at a certified point that is a point where the first condition is satisfied due to an event that does not require the storage of the first information, even if the first condition is met again, the first condition will not be saved. It is preferable to have a configuration in which no information is stored. This is good because the amount of data to be stored can be reduced. Particularly, when an event that does not require storing the first information occurs at the same point every time, it is possible to avoid having to store the first information every time. This is good because it can prevent the storage capacity of the storage medium that stores the first information from becoming full.

In particular, at a point other than the certified point, the first information may be stored when the first condition is satisfied. Thereby, the first information may be stored at a point where the first condition is satisfied due to an event that requires storage of the first information. For example, an event that does not require memorization of the first information does not occur at the same point every time, but at a point where an event that requires memorization of the first information occurs, it is not possible to memorize the first information. It's good because it can be done. This is good because the really necessary first information can be stored.

Further, it is preferable that the present device is realized by a device including the function of a drive recorder. By doing so, the present device can be realized by hardware for realizing the functions of a drive recorder. For example, it is preferable to operate software for realizing the functions of the present device by using an arithmetic processing device that performs arithmetic processing for realizing the functions of the drive recorder and a storage device. Further, for example, it is preferable to determine whether or not the first condition is satisfied by using a measurement result by a sensor for realizing the function of the drive recorder. In particular, it is preferable that the sensor is an acceleration sensor, and it is determined whether the first condition is satisfied based on the acceleration measured by the acceleration sensor. Furthermore, for example, the control target for the control for storing the first information may be the control for storing information by the function of the drive recorder.

Further, the "first condition" may be a predetermined pattern of predetermined information, and the predetermined information may be information that changes as the moving body moves. For example, it may be assumed that "information that changes as the moving body moves" has a predetermined pattern. The "predetermined pattern" may be a case in which a predetermined state continues or a state that has a predetermined correlation with a pre-stored pattern, but in particular, the following (2) It is better to do this. In addition, when the impact that occurs when a moving object is involved in a collision, or when an abnormality such as sudden braking or sudden steering occurs to avoid an accident, is detected, It is preferable to make the information that changes according to a predetermined pattern. By doing so, it is possible to store the first information when an abnormality such as sudden braking or sudden steering occurs in order to avoid a collision or an accident.

In addition, the "first information" may be information related to the event that caused the first condition to be satisfied, such as the inside of the moving body or the surrounding area of the moving body captured by an imaging device mounted on the moving body. It is preferable to use the image data of . By doing so, it is possible to confirm the situation inside the moving body and around the moving body when the first condition is satisfied. Furthermore, although the image data serving as the first information may be a still image, it is preferably a moving image recorded before and after the first condition is satisfied, including the time when the first condition is satisfied. By doing so, it is possible to check not only the time when the first condition is satisfied, but also the situation before and after the first condition is satisfied.

Furthermore, the "event that does not require storage of the first information" may be an event that is not intended as a target event that requires storage of the first information in light of the purpose of the device. By doing so, it is possible to prevent the first information from being stored even though an unintended event has occurred.

In particular, the use of this device may be to control information stored by a drive recorder. For example, it may be possible to control whether or not to store video data when the drive recorder detects an impact. In this case, for example, if it is erroneously detected that the impact is not caused by an accident but is caused by passing over a step, control may be performed so that the video data is not stored. On the other hand, if the impact is due to an accident or the like, control may be performed to store video data. By doing so, it is possible to prevent the storage capacity of the storage medium from becoming full. Furthermore, since it is possible to prevent the storage capacity of the storage medium from becoming full, it is possible to store and preserve images that are really necessary, such as images taken when an accident or the like occurs.

Furthermore, the "certified point" may be a point recognized as a point where the first condition is satisfied due to an event that does not require storage of the first information. For example, if the first condition is satisfied due to a moving object passing a certain point, but it is recognized that this is due to an event that does not require the storage of the first information. , this certain point may be designated as a certified point. The certified point may be certified, for example, in response to a user's operation. By doing so, it is possible to perform accurate certification based not only on the criterion of whether or not the first condition is satisfied, but also on the user's judgment.

(2) A device characterized in that the first condition is that measurement information that changes with movement of a mobile body equipped with the device changes to predetermined information.

In this way, it is preferable to adopt a configuration in which it is determined whether or not to store the first information based on the measurement information that changes with the movement of the mobile object equipped with the present device. By doing so, the first information can be stored depending on the movement status of the mobile object. Furthermore, it is preferable that the present device measures information that changes as the moving object moves. By doing so, the processing can be completed by this device.

Further, even if the first condition is satisfied depending on the movement status of the mobile object, the first information may not be stored at the certified point. This eliminates the need to store the first information based only on the movement status of the mobile object.

(3) when the first condition is met, storing second information that is information that specifies the location of the point where the first condition is met;
When the second condition is met, output the second information that specifies the location of a point other than the certified point, but do not output the second information that specifies the location of the certified point. A device featuring:

In this way, when the second condition is satisfied, it may be configured to output information specifying a point other than the authorized point where the first condition is satisfied. This makes it possible to specify a point at the output destination where the first condition is satisfied.

Further, in this way, it is preferable to adopt a configuration in which information specifying the location of the certified point is not output. As a result, both the information specifying the point other than the certified point where the first condition is satisfied and the information specifying the location of the certified point are output, resulting in an excessive amount of output information. This is good because it can prevent

"Output" may be performed, for example, by displaying it on a screen for reference by the user. In this case, the user can specify a point other than the certified point where the first condition is satisfied. Further, in this case, since the information specifying the certified point is not output on the screen that the user refers to, it is possible to prevent the screen from becoming difficult to see.

The "second information" may be, for example, an icon displayed on a map. In this case, it is preferable to vary the display mode of the icons depending on the degree to which the first condition is satisfied, the order in which the first condition is satisfied, and the like. For example, the display mode may be varied by changing the color of the icon, changing the shape, or adding numbers. By doing so, the user who refers to the map and the icon can recognize the extent to which the first condition is satisfied, the order in which the first condition is satisfied, and the like.

The "second condition" may be a condition that is satisfied when a situation arises in which it is desirable to refer to the second information at the output destination. For example, the second condition may be to display a map that the user refers to. In particular, it is better to do as described in (4) below.

(4) A device characterized in that the second condition is that the device approaches a point where the first condition is satisfied.

In this way, the second condition is that the device approaches a point where the first condition is met, and when the second condition is met, the point where the first condition is met is identified. It is preferable to have a configuration that outputs information. This allows the output destination to know that the first condition was satisfied in the past near the device.

The output may be performed, for example, on a screen that the user refers to. This allows the user to know that the first condition was satisfied in the past near the current location of the device.

(5) An apparatus characterized in that, when a third condition is satisfied, the second information specifying the position of the certified point is output.

In this way, the configuration may be such that when the third condition is met, the second information specifying the position of the certified point is output. This is good because the location of the certified point can be specified at the output destination. The output may be performed, for example, on a screen that the user refers to. In this way, the user can specify the location of the certified point. By doing this, for example, it is possible to know in advance that since the vehicle will pass through the certified point, an event in which the first condition is satisfied will occur again. Moreover, it is good because it is possible to understand why the first information is not stored even though the first condition should have been satisfied.

The "third condition" may be a condition that is satisfied when a situation arises in which it is desirable to refer to the location of the certified point at the output destination. For example, the third condition may be that an operation for confirming the location of the certified point has been received from the user.

(6) An apparatus characterized in that the second information about the certified point and the second information about points other than the certified point are displayed in different display modes.

In this way, the second information, which is the information for specifying the position of the point where the first condition is satisfied, may be configured to be output in different display modes for the certified point and other points. This allows the output destination to distinguish between the location of the certified point and the location of a point other than the certified point where the first condition is satisfied.

(7) An apparatus characterized in that the certified point is determined based on a user's operation with reference to stored information when the first condition is satisfied.

In this way, it is preferable to adopt a configuration in which the certified point is determined based on the user's operation. Thereby, the certified point can be determined more accurately than if the certified point is determined automatically by the device. Further, there is no need to set in the device what criteria to use for determining whether or not a point is a certified point.

Moreover, in this case, the user determines the certified point after referring to the stored information when the first condition is satisfied. This is advantageous because the authorized point can be determined more accurately than when no information is referred to.

It is preferable that the information stored when the first condition is satisfied be either the first information or the second information, but it is even better to use both because the user has more information to make a decision.

The first information may be, for example, image data captured when the first condition is satisfied. By doing so, the user can refer to the image data and determine whether or not it is a certified point.

The second information may be, for example, information that specifies the position of a point that satisfies the first condition. By doing so, the user can determine whether or not the point is an authorized point after grasping the position of the point that satisfies the first condition.

(8) The first condition includes the condition 1-1 and the condition 1-2, and the condition 1-1 is canceled due to an event that does not require the storage of the first information. At the certified point where it has been determined that the above-mentioned condition 1-1 is satisfied, the control for storing the first information is not performed if the above-mentioned condition 1-1 is satisfied again, but if the above-mentioned condition 1-2 is satisfied. An apparatus characterized in that the device performs control to store the first information when the condition is satisfied.

In this way, even if a point becomes a certified point after satisfying condition 1-1 due to an event that does not require memorization of the first information, even if condition 1-1 is met again. , it is preferable to adopt a configuration in which the first information is not stored. This is good because the amount of data to be stored can be reduced. Particularly when the same event occurs at the same point every time, it is advantageous because the first information does not have to be stored every time. For example, if there is a difference in level, the same degree of shock will occur each time the user passes through this point, but this is good because the first information will not be stored each time at such a point.

In addition, even if the point becomes a certified point after satisfying the condition 1-1, if the condition 1-2 is satisfied, the first information is stored. good. As a result, even if the point is once certified as a certified point, the first information can be stored if condition 1-2 is satisfied. In particular, even if the same event occurs at the same point every time, the first information can be stored if a different event occurs at the point instead of the same event. For example, if there is a difference in level, the same degree of impact will occur each time you pass this point, but if the impact is not the same degree but is greater than that, the first information may not be memorized. It's good because it can be done.

The "1-1st condition" and the "1-2nd condition" may be further differentiated from the first condition. For example, if the first condition is that the measured acceleration exceeds a threshold, multiple thresholds will be set, and if the first threshold is exceeded, condition 1-1 will be satisfied. , if the second threshold value, which is a larger value than the first threshold value, is also exceeded, it is preferable that condition 1-2 is satisfied. By doing this, if an accident or the like occurs at the certified point and a shock larger than the impact normally detected is caused by a step at the certified point, the first information can be stored. This is good because it allows you to

(9) The first condition includes a plurality of conditions in stages according to the size of the threshold value, and when the conditions are arranged in order from the smallest threshold value, the first condition 1-2 is , a plurality of conditions including a condition that is the next order after the 1-1 condition, or a condition that is after the 1-1 condition.

In this way, if either the condition that is the next order after the condition 1-1 or the condition that is after the next order in order of decreasing threshold value is satisfied, the first information is stored. It is a good idea to control it. As a result, at a point that was designated as a certified point because condition 1-1 was met, even though condition 1-2, which is the next in order after condition 1-1, was met, This is good because it can prevent a situation in which the first information is not stored.

For example, when conditions are arranged in descending order of threshold value, it is assumed that n conditions are arranged, such as condition 1, condition 2, condition 3, . . . condition n. The first information is not stored even if Condition 1 is satisfied again at a point that is designated as a certified point because Condition 1 is satisfied. This is because Condition 1 is only satisfied every time due to the difference in level at the certified point, and no accidents have occurred. In addition to this, it is also conceivable to not store the first information even if Condition 2 or Condition 3 is satisfied, for example. However, if all of the conditions that are set in stages are set such that the first information is not memorized, it may happen that the first information is not memorized even though it is an event that should be memorized. It is possible that a situation may arise. For example, consider a case where, due to an accident or the like, condition 2, which has a higher threshold value, is satisfied instead of condition 1, which is satisfied every time due to a difference in level at the certified point. In this case, since an accident or the like has occurred, it is preferable to store the first information. Therefore, it is preferable to allow the first information to be stored if at least condition 2 is satisfied.

(10) The first condition includes a plurality of conditions in stages according to the size of the threshold, and if at least the condition with the highest threshold is satisfied, even at the certified point, the A device characterized in that it stores first information.

In this way, if the condition with the highest threshold value among the plurality of conditions according to the threshold values is satisfied, the first information may be stored without asking whether it is a certified point. This is good because it is possible to prevent a situation where the first information is not stored even though the condition with the highest threshold value is satisfied.

In the case where a plurality of threshold values are provided, even if an impact that exceeds the highest threshold occurs, it may be possible to not store the first information if that is the certified point. However, in this case, even if an extremely large impact occurs, the first information will not be stored. The occurrence of such a significantly large impact is considered to be caused by an accident or the like. Therefore, it is preferable to store the first information. Therefore, as described in (10), it is preferable to store the first information when the highest threshold value is exceeded.

(11) The device is characterized in that the certified point is defined by a distance range representing the certified point and a passing direction when passing through the certified point.

In this way, it is preferable to define the certified point not only by the distance range but also by the passing direction when passing through the certified point. By doing so, if the vehicle enters the distance range of the authorized point from a certain direction, it can be determined that the vehicle is within the defined authorized point. On the other hand, if the vehicle enters the distance range of the authorized point from another direction, it can be determined that it is not within the defined authorized point.

For example, if you enter the distance range of the certified point from a certain direction, the first condition will be satisfied every time, but if you enter the distance range of the certified point from another direction, the first condition will be satisfied every time. At a point where condition 1 is not satisfied, the configuration described in (11) may be used. This is because it is preferable that a point where the first condition is met every time is determined to be a certified point even if the first condition is met, and the first information is not recorded.

For example, assume that one lane of a two-lane road (temporarily assumed to be an up lane) has a level difference, and the other lane (tentatively assumed to be an outbound lane) has no level difference. In this case, when the vehicle enters the distance range of the certified point from the up lane, a certain amount of impact occurs due to passing over a step each time. Therefore, in this case, it is preferable not to store the first information as having passed through the certified point. On the other hand, if you enter the distance range of the certified point from the down lane, there is no step, so normally no impact will occur. If a shock were to occur, it would probably be caused by an accident or the like. Therefore, in this case, it is preferable to store the first information assuming that the vehicle has not passed through the certified point. Therefore, considering the case where it is necessary to make a difference in whether or not to memorize depending on the direction of passage, as in (11) above, it is necessary to pass through the certified point not only in the range of distance, but also in the range of distance. It is preferable to define the current passing direction and then determine whether or not the vehicle has passed through a certified point.

(12) If the first condition is met consecutively at multiple points at intervals less than a predetermined time interval, and all of the multiple points are certified points, the multiple points are certified. An apparatus characterized in that points are grouped into one group and outputs not information specifying the position of each of the plurality of certified points, but information specifying the position of this one group.

In this way, if there are consecutive points where the first condition is satisfied and each of these multiple points is a certified point, these multiple points are considered as one group, and the positions of one group are specified. It is recommended that the configuration outputs the information that Further, in this way, it is preferable to adopt a configuration in which a plurality of pieces of information specifying the respective positions of a plurality of points are not output.

By doing so, at the output destination, instead of outputting each piece of information that specifies a plurality of points, the information that specifies the position of one group is outputted. For example, the output destination may be set to a screen that the user refers to. By doing so, it is possible to prevent all of the information specifying the positions of a plurality of points from being displayed and the screen becoming difficult to view. Also, although information specifying the location of each of multiple points is not displayed, information specifying the location of one group is displayed, so the user can understand that multiple certified points exist at that location. good.

BACKGROUND OF THE INVENTION Some roads are constructed with a series of steps in order to reduce driving speed and alert drivers of moving vehicles by generating sound and vibrations. When passing through such a road, the first condition is continuously satisfied. However, if information for specifying each point is output for each point that satisfies the first condition, a large amount of information will be output. Therefore, by treating each of these points as one group and outputting information specifying the position of this one group, it is possible to prevent the amount of output information from increasing unnecessarily.

(13) A point that is certified as the above-mentioned certified point in either or both of the following cases: a predetermined period of time has passed since the point was certified as the above-mentioned certified point, and the number of certified points has reached the predetermined number. A device characterized in that part or all of the area is not treated as the certified point.

In this way, if a predetermined period of time has elapsed since the point was certified as a certified point, it may be configured such that the point is not treated as a certified point. By doing so, the number of certified points can always be kept below a predetermined number.

This is good because it can prevent the number of authorized points from becoming enormous. If the number of certified points becomes enormous, a large number of certified points will be output when outputting information that specifies the location of the certified points. It is preferable to prevent it from being put away.

In particular, if the device is used continuously for a long period of time, the number of certified points will increase as the period of use becomes longer, so it is preferable to reduce the number of certified points in this way.

(14) An apparatus characterized in that, if the first condition is not satisfied even though the vehicle has passed through the certified point, the certified point is not treated as the certified point.

In this way, if the first condition is not met even though the vehicle has been certified as a certified point, and the first condition is not met even though the vehicle has passed through the certified point, the certified point will not be treated as the certified point. good. This is good because a point that should no longer be a certified point is not treated as a certified point.

For example, suppose that there is a level difference at a certain point, so that an impact that satisfies the first condition occurs every time the object passes over it. In this case, this certain point is designated as a certified point. However, if the situation changes and, for example, the level difference disappears, an impact that satisfies the first condition will not occur even if the vehicle passes this certain point. In such a case, it is preferable not to treat this certain point as a certified point. This is because even though the point was certified as a certified point because it satisfies the first condition every time it is passed, due to changes in the situation, it has become a point where the first condition is not met even if the point is passed. .

(15) It is equipped with a drive recorder function and a car navigation function, and the first information is image data captured by the drive recorder function, and the first information is the image data captured by the drive recorder function due to an event that does not require storage of the image data captured by the drive recorder function. A point where the first condition is satisfied is defined as the certified point, and information specifying the location of a point other than the certified point that satisfies the first condition is displayed on the map displayed by the car navigation function. A device characterized by displaying.

In this way, it is preferable to adopt a configuration in which image data captured by the drive recorder function is stored when the first condition is satisfied. Thereby, even after the first condition is satisfied, the image data captured by the drive recorder function can be used. "Image data captured by the drive recorder function" refers to, for example, an image of the surroundings of a moving object that is captured when the moving object on which this device is installed receives a certain impact due to contact with another object. It is better to convert it into data.

In addition, at certified points where the first condition is satisfied due to an event that does not require storage of image data captured by the drive recorder function, the image data captured by the drive recorder function is not stored. It is better to configure it so that it is not memorized. This is good because it is possible to prevent image data resulting from an event that does not require storage of image data from being stored every time the authorized point is passed. The event that does not require storage of image data may be, for example, when a moving object on which the device is mounted passes a step. The first condition being satisfied due to an event that does not require storage of image data may be, for example, that an impact is detected as a result of a moving object on which the device is mounted passing a step. .

Furthermore, in this way, when information specifying the position of a point that satisfies the first condition is displayed on the map displayed by the car navigation function, information specifying the position of the certified point is not displayed. good. This is good because it can prevent more information than necessary from being displayed on the map. "Displaying information that specifies the location of a point that satisfies the first condition on a map displayed by the car navigation function" means, for example, specifying the location of a point that satisfies the first condition on the map. It is a good idea to display an icon.

(16) A program that causes a computer to function as the device described in any one of (1) to (15) above.

In this way, by providing a program that causes a computer to function as the device described in any one of (1) to (15) above, all or at least one of the functions of the device described in (1) to (15) above can be achieved. This is advantageous because it allows the parts to be realized by a computer.

According to the present invention, it is possible to prevent processing that should be performed when an accident or the like actually occurs even though the occurrence of an accident or the like is erroneously detected.

<Functional block>
First, the configuration of an integrated device 1000 according to this embodiment will be described with reference to FIG. FIG. 1 is a block diagram showing functional blocks included in an integrated device 1000.

Referring to FIG. 1, the integrated device 1000 includes a first control section 100, a touch panel 110, a speaker 120, a notification LED 130, a button 140, a TV tuner 150, a GPS sensor 160, an acceleration sensor 170, a first storage section 180. , a main storage section 190, a second control section 200, a camera 210, a microphone 220, a second storage section 230, a power supply section 310, and a USB terminal 320.

Here, the first control unit 100 is a control unit that exclusively functions as a car navigation device. On the other hand, the second control unit 200 is a control unit that exclusively functions as a drive recorder. The first control unit 100 and the second control unit 200 realize control of the integrated device 1000 by working together. In other words, the integrated device 1000 is a device that has both the functions of a car navigation device and a drive recorder. In the following description, it is assumed that the integrated device 1000 is installed and used on the dashboard of an automobile, which is a moving object.

Next, the functions of these parts will be explained in more detail.

The first control unit 100 includes, among other parts, a touch panel 110, a speaker 120, a notification LED (Light Emitting Diode) 130, a button 140, a television tuner 150, a GPS (Global Positioning System) sensor 160, and an acceleration sensor. 170, controls the first storage section 180 and the main storage section 190.

Specifically, the first control unit 100 inputs the details of the operation received by the touch panel 110. It also outputs image data to be displayed to the touch panel 110. Further, the first control unit 100 outputs sounds such as music and voice to be output to the speaker 120. Furthermore, the first control unit 100 notifies the user by lighting or blinking the notification LED 130.

Further, the first control unit 100 controls the television tuner 150 according to the operation received by the touch panel 110.

Furthermore, the first control unit 100 inputs position information determined by the GPS sensor 160. Furthermore, the first control unit 100 inputs the acceleration measured by the acceleration sensor 170.

Furthermore, the first control unit 100 writes information to the first storage unit 180. Furthermore, the first control section 100 reads information from the first storage section 180.

Furthermore, the first control unit 100 writes information to the main storage unit 190. Furthermore, the first control unit 100 reads information from the main storage unit 190.

Further, the first control section 100 is connected to a communication line mounted on the board, and communicates with the second control section 200.

Furthermore, the first control unit 100 communicates with an external device connected via the USB terminal 320.

The touch panel 110 receives an operation by pressing the screen from the user, and outputs the content of the received operation to the first control unit 100. Here, the content of the operation is information that specifies the position on the screen of the touch panel 110 at which the press is accepted. Furthermore, the touch panel 110 displays image data input from the first control unit 100 on the screen. Furthermore, the touch panel 110 displays image data input from the television tuner 150 on the screen.

The speaker 120 outputs sounds such as music and voice input from the first control unit 100.

The notification LED 130 lights up or blinks based on the control of the first control unit 100.

The button 140 is a physical button 140 provided on the casing of the integrated device 1000, and accepts user operations.

Here, when the integrated device 1000 is installed and used in a car as described above, the touch panel 110, the speaker 120, and the notification LED 130 are connected to each other by the user. Placed in a position where it can be detected. Further, the touch panel 110 and the buttons 140 are arranged at positions where the user can operate them.

The television tuner 150 receives a television signal, converts the received television signal into image data in a predetermined format, and outputs the image data to the touch panel 110. In the following description, the image data converted by the television tuner 150 will be referred to as "television video."

The GPS sensor 160 uses GPS to measure the current position of the integrated device 1000 and outputs the measured position information to the first control unit 100. Here, the position information is realized by, for example, coordinate information based on the GPS standard.

The acceleration sensor 170 measures acceleration and inputs the measured acceleration to the first control unit 100. Note that the acceleration sensor 170 is sometimes called a "G sensor".

The first storage unit 180 is a part into which a removable storage medium is inserted by the user. A storage medium storing, for example, a music file in the MP3 (MPEG-1 Audio Layer-3) format or a television video written by the first control unit 100 is inserted into the first storage unit 180. Under the control of the first control section 100, these music files and television images are read from a storage medium inserted into the first storage section 180 and output from the speaker 120 and the touch panel 110.

The main storage unit 190 stores information for car navigation. Specifically, map information, information regarding certain targets, information for specifying the type of road, information on facilities, address information, etc. are stored. Further, the main storage unit 190 stores software for realizing control by the first control unit 100.

Furthermore, the software in the main storage unit 190 can be updated using the latest software data, the latest data regarding the target, etc. that are updated after the integrated device 1000 is shipped. For example, a storage medium storing the latest data is inserted into the first storage unit 180, and the first storage unit 180 reads additional data from this storage medium to update the software in the main storage unit 190. Here, the main storage unit 190 is realized by, for example, a flash memory.

Furthermore, when the integrated device 1000 is installed and used in a car as described above, the current position measured by the GPS sensor 160 represents the current position of the car, and the acceleration measured by the acceleration sensor 170 represents the car's current position. It represents acceleration. Then, the first control unit 100 creates a map for driving guidance including the current position of the vehicle by comparing the current position measured by the GPS sensor 160 with the map information stored in the storage unit. , this map for operation guidance is displayed on the touch panel 110. Further, predetermined information, warnings, and messages are output using the touch panel 110, the speaker 120, and the notification LED 130. The first control unit 100 performs these processes to realize a car navigation function.

On the other hand, the second control unit 200 controls the camera 210, the microphone 220, and the second storage unit 230, among other units mentioned above.

The second control unit 200 inputs the video signal captured by the camera 210 and the audio signal collected by the microphone 220, converts the input video signal and audio signal into image data in a predetermined format, and converts the input video signal and audio signal into image data in a predetermined format. Store in. In the following description, the image data converted by the second control unit 200 will be referred to as "real-time video."

Further, the second control unit 200 outputs real-time video to the first control unit 100. The output real-time video is displayed on the touch panel 110.

Camera 210 includes an incident section 211.

The entrance part 211 is a part into which light enters. The light incident on the incidence section 211 is converted into a video signal and output to the second control section 200.

Furthermore, the microphone 220 collects sound. The sound collected by the microphone 220 is converted into an acoustic signal and output to the second control section 200.

Here, when the integrated device 1000 is installed and used in a car, the light incident on the incident part 211 and the sound collected by the microphone 220 become objects to be imaged by a drive recorder. Here, the objects to be imaged by the drive recorder are, for example, scenery in the direction of travel and surrounding sounds imaged from inside the car through the windshield. The second control unit 200 realizes the function as a drive recorder by storing the object to be imaged by the drive recorder in the second storage unit 230 in a predetermined video format.

The power supply section 310 supplies power to each functional block included in the integrated device 1000. Power is supplied to the power supply section 310 from an external device via the USB terminal 320. Note that in FIG. 1, illustration of wiring for the power supply section 310 to supply power to each functional block is omitted.

The USB terminal 320 is a terminal compliant with the USB standard. The USB terminal 320 is connected to an external device via a cable compliant with the USB standard. Power is then supplied from the external device via the cable. It is also possible for the first control unit 100 and an external device to communicate via a cable.

Here, when the integrated device 1000 is installed and used in a car, a cable connected to a car charger of the car is connected to the USB terminal 320. The integrated device 1000 is then supplied with power from the car charger of the automobile.

The functional blocks of this embodiment have been described above.

Note that the first control unit 100 and the second control unit 200 described above are each realized by an arithmetic device such as a CPU (Central Processing Unit), a RAM (Random Access Memory), a ROM (Read only memory), etc. Ru. The control by the first control section 100 and the second control section 200 is realized by the CPU reading the software stored in the ROM or the main storage section 190 and performing arithmetic processing while expanding it in the RAM.
<Processing of this embodiment>
Next, each of the processes performed by this embodiment will be described in detail with reference to the drawings.
<Real-time video recording>
First, real-time video recording performed under the control of the second control unit 200 will be described with reference to FIG. 2. In this embodiment, there are three recording methods: continuous recording, manual recording, and event recording.

First, as a premise, imaging is performed when the engine of the automobile in which the integrated device 1000 is installed is started, and real-time image acquisition is started. Imaging ends when the car engine is stopped, and real-time image acquisition ends accordingly.

Here, whether or not the engine of the automobile is operating may be determined depending on, for example, whether power is supplied from the automobile via the USB terminal 320. That is, if power supply is started, real-time video acquisition is started, and if power supply is terminated, real-time video acquisition is ended.

Next, constant recording will be explained. The real-time video is stored in the second storage unit 230 from the start of real-time video acquisition until the real-time video acquisition ends. In other words, recording is always performed while the car engine is running.

The recorded real-time video is divided into a plurality of files in units of predetermined length and stored in the second storage unit 230. Although the unit of the predetermined length is arbitrary, for example, one file may be set in units of 30 seconds. Note that in the following explanation, this file will be referred to as a "video file."

As shown in "From startup until the capacity of the second storage unit 230 is full" in the upper left of FIG. Saving of the video file continues. Although the capacity allocated for constant recording is arbitrary, it is preferable that the capacity be set such that a video file corresponding to a length of 20 minutes can be recorded, for example.

Further, even after the capacity of the second storage unit 230 allocated for continuous recording becomes full, storage of video files continues. However, as it is, there is not enough capacity to save new video files. Therefore, when saving a new video file, it is recommended to delete the oldest video file first.

Next, manual recording will be explained. When detecting that the user presses the button 140 or the touch panel 110, the second control unit 200 executes manual recording. Specifically, when the first control unit 100 detects that the user presses the button 140 or the touch panel 110, the first control unit 100 instructs the second control unit 200 to perform manual recording. Upon receiving this instruction, the second control unit 200 protects the video file including the point in time when the press of the button 140 or the press of the touch panel 110 is detected, and the video file immediately before the video file. In other words, two video files are protected in response to one press. Protecting here means excluding the protected video file from the deletion of the oldest video file due to constant recording.

Then, the two protected video files, the date and time of manual recording, and location information specifying the location where the two video files were captured are linked together and stored in the second storage unit 230 as a set. Also, in order to identify this current manual recording, it is necessary to further add an identifier to the set. For example, the date and time of manual recording may be used not only to confirm the date and time, but also as an identifier. Further, as the position information, it is preferable to request the first control unit 100 for coordinate information measured by the GPS sensor 160, and use the coordinate information transmitted from the first control unit 100 in response to the request. Alternatively, when the first control unit 100 instructs execution of manual recording, coordinate information may also be transmitted, and the second control unit may use the transmitted coordinate information.

Further, the second control unit 200 notifies the first control unit 100 that manual recording has been performed. Specifically, the fact that manual recording was performed, the date and time when manual recording was performed, and location information that specifies the location of the point where manual recording was performed are linked to form a pair, and this pair and this manual recording are identified. The identifier for the first control unit 100 is sent to the first control unit 100. Then, the first control unit 100 stores the received set of information and its identifier in the main storage unit 190.

The number of cases that can be protected may be arbitrarily determined depending on the capacity of the second storage unit 230, but for example, it is preferable to set the capacity to a maximum of 10 cases, that is, 20 video files. When 20 video files are protected and a user presses the button 140 and executes a new manual recording, or when newly executing an event recording described below, the oldest Two video files, which are the video files for one incident, are excluded from protection and deleted. This allows new video files to be protected.

Next, event recording will be explained. When the first control unit 100 determines that an event has occurred, the second control unit 200 executes event recording. Here, an event is an event for which real-time video should be recorded. In other words, when an event for which real-time video should be recorded occurs, it is determined that the event has occurred. In addition, events for which real-time video should be recorded include, for example, collisions that require video recording using the drive recorder function, and abnormalities such as sudden braking or sudden steering to avoid accidents. It is. However, events such as collisions and abnormalities such as sudden braking and sudden steering to avoid accidents are only examples of events, and these events may not be treated as events. Other phenomena may also be treated as events.

When the first control unit 100 determines that an event has occurred, the date and time when the event occurred and the location information that specifies the location of the point where the event occurred are linked, and this pair and this pair are linked. An identifier for specifying the event recording is stored in the main storage unit 190.

Further, when the first control unit 100 determines that an event has occurred, the event is linked and assembled with the fact that the event has occurred, the date and time of the event, and location information that specifies the location of the point where the event occurred. As a result, the first control unit 100 notifies the second control unit 200 of an identifier for identifying this group and the current event recording. The second control unit 200 that has received this notification executes event recording. Note that how the first control unit 100 determines that an event has occurred will be explained after the description of the event recording.

The second control unit 200 that executes event recording protects the video file including the time point at which the event occurred and the video file immediately before the video file. In other words, two video files are protected when a single event occurs.

Then, the two protected video files, the date and time when the event occurred, and the location information that specifies the location where the two video files were captured are linked together to form a set, and a link is created to identify this set and the current event recording. The identifier is stored in the second storage unit 230. Also, similar to manual recording, it is preferable to use the date and time when an event occurred as an identifier. Furthermore, it is preferable to use the coordinate information transmitted from the first control unit 100 for the position information, similarly to manual recording.

As with manual recording, the number of cases that can be protected may be arbitrarily determined depending on the capacity of the second storage unit 230. It is recommended to have a capacity for 20 pieces. As with manual recording, if you want to perform further recording with 20 video files protected, remove the two video files that are the video files for the oldest case from protection. It is recommended that you delete it.

The video file recorded in this way can be played back according to the user's operation. For example, as shown in FIG. 3, a list is displayed on the touch panel 110 using the date and time when a protected video file was captured as an identifier. Then, a selection by the user is accepted on the touch panel 110, and a video file corresponding to the selection is reproduced on the touch panel 110. Note that so that the user can distinguish between manual recording and event recording, manual recording is marked with an icon such as i1 in Figure 3, and event recording is marked with an icon such as i2 in Figure 3, which has a different shape from i1. I'm trying to add an icon like this.

<Determining the occurrence of an event>
In this embodiment, the first control unit 100 determines that an event has occurred.

In order to determine that this event has occurred, the acceleration measured by the acceleration sensor 170, which is measurement information that changes as the vehicle moves, and a predetermined threshold are used. Then, when the measured acceleration exceeds this predetermined threshold value, it is determined that an event has occurred. By doing this, it is possible to detect that an event has occurred, such as when a car collides with another moving object or installation, or when there is a sudden stop, sudden call, or sudden turn based on the driving of the user operating the car. can be determined.

Further, instead of only one threshold value, a plurality of threshold values are provided in stages. By determining which of the threshold values set in stages the measured value of the acceleration sensor 170 has exceeded, it is possible to determine not only whether the vehicle has collided with another moving object or an installed object, but also the impact of the collision. It is also possible to determine the extent of

For example, the threshold value at the most sensitive stage is set to 0.5G, and the sensitivity is gradually decreased from there. In other words, the threshold for the second most insensitive stage is 0.8G, the threshold for the middle stage is 1.1G, the threshold for the second most insensitive stage is 1.4G, the threshold for the most insensitive stage is 1.7G, and so on. For example, five steps are set.

If the measured value of the acceleration sensor 170 is, for example, less than 0.5G, it is not determined that an event has occurred. Further, if the measured value of the acceleration sensor 170 is, for example, 0.9 G, it is determined that a level 2 event has occurred since it exceeds the threshold value of the second insensitive stage. Further, if the measured value of the acceleration sensor 170 is, for example, 1.9G, it is determined that a level 5 event has occurred since it exceeds the threshold value of the least sensitive stage. In this way, the higher the measured value of the acceleration sensor 170, the more it is determined that a high-level event has occurred. In other words, the higher the level of the event, the greater the impact was detected.

When it is determined that an event has occurred, the first control unit 100 links the location information for specifying the location where the event occurred, the level of the event that occurred, and the date and time that the event occurred and creates a set. , this pair and an identifier for identifying the current event are stored in the main storage unit 190. Further, it is preferable that the second control unit 200 uses the date and time when an event occurs as an identification code to identify each event, in the same way as the second control unit 200 does when performing manual recording or event recording. .

Further, as described above, when the first control unit 100 determines that an event has occurred, the second control unit 200 executes event recording. Specifically, when the first control unit 100 determines that an event has occurred, the second control unit 200 is notified of this fact. The second control unit 200 that has received this notification executes event recording. Note that the method for executing event recording by the second control unit 200 is as described above in the section <Real-time video recording>.

Furthermore, when it is determined that an event has occurred, the first control unit 100 notifies the user of the occurrence of the event by lighting or blinking the notification LED 130. In addition, the first control unit 100 also pops up a message such as "An **** event has occurred" on the touch panel 110.

For example, if you are using the navigation function, a message will pop up on the map. A display example of this message is shown in FIG.

First, as shown in FIG. 4, a map for operation guidance is displayed on the entire touch panel 110. Further, i3 shown in FIG. 4 is a message that is displayed as a pop-up to indicate the occurrence of an event. For example, the level of the event that has occurred is displayed in "＊＊＊＊＊" of this message. For example, it is preferable to display something like "An event of level 3 has occurred." Furthermore, such a message is urgent and should be conveyed to the user immediately. In other words, it is highly important as information to be conveyed to the user. Therefore, when using a function other than the navigation function, for example, even when a TV video is being played, it is preferable to display a pop-up message on the TV video.

Further, in area i4 shown in FIG. 4, there is provided an area where various information used for operation guidance is displayed. In the example shown in FIG. 4, in this area, from the top, the current time obtained from the GPS satellite, the reception strength and direction of the GPS signal, a value representing the scale of the map, and a shortcut button are arranged.

Here, the shortcut button is a button for switching information displayed on the screen each time the button is pressed. Switching of the information displayed on the screen when the shortcut button is pressed, that is, the transition of the screen, will be described later, so a detailed explanation will be omitted here.

Further, in i5 shown in FIG. 4, the current traveling speed of the automobile in which the integrated device 1000 is installed is displayed as per hour.

Further, in i6 shown in FIG. 4, information related to the location where the car in which the integrated device 1000 is installed is currently traveling is displayed. Information related to the point where the vehicle is currently traveling includes, for example, the address, road name, latitude and longitude of the location where the vehicle is traveling. It is also good to display a menu screen when i6 shown in FIG. 4 is pressed.

<False detection certified point>
Next, the recognition of the false detection recognition point, which is a process unique to this embodiment, will be described.

As described above, the integrated device 1000 according to this embodiment includes both the function as a drive recorder and the function as a car navigation device. Then, it is determined whether an event has occurred by functioning as a drive recorder. Furthermore, if it is determined that an event has occurred, event recording is performed. Furthermore, an icon or the like for specifying the position of the point where it is determined that the event has occurred is displayed on the map displayed by the function as a car navigation device.

Here, as described in the above section <Determination of occurrence of event>, in this embodiment, it is determined that an event has occurred when the measured value of the acceleration sensor 170 exceeds a predetermined threshold value. In other words, the determination is made based on the premise that the fact that the measured value of the acceleration sensor 170 exceeds a predetermined threshold value means that an event has occurred.

However, a judgment based on such a premise is not necessarily correct, and even if the measured value of the acceleration sensor 170 exceeds a predetermined threshold value, there may be a case in which an event does not actually occur. In other words, there may be a case where it is falsely detected that an event has occurred even though the event has not occurred.

Various cases can be considered as causes for such erroneous detection. For example, there may be a difference in level on the road. When a certain point on a road has a step with a drop of more than a certain level, a certain amount of impact is generated every time a car passes that certain point. Therefore, each time the car passes through that certain point, the measured value of the acceleration sensor 170 exceeds a predetermined threshold, and the first control unit 100 detects the occurrence of an event.

Furthermore, even if there is no difference in level, for example, if the road has a sharp curve, the vehicle makes a sharp turn every time the vehicle passes through the curve. Therefore, it is conceivable that the measured value of the acceleration sensor 170 exceeds a predetermined threshold value, and the first control unit 100 detects the occurrence of an event.

However, it is considered undesirable to determine that an event has occurred and perform event recording simply because the vehicle passes over a step or makes a sharp turn due to the structure of the road.

This is because, in light of the drive recorder's functions, events that should be treated as events include, for example, a collision occurring, or abnormal operations such as sudden braking or sudden steering to avoid an accident. This is because this is a phenomenon.

On the other hand, simply passing over a step or making a sudden turn that is unavoidable due to the structure of the road are not events that should be treated as events in light of the drive recorder's function. Nevertheless, if it is erroneously detected that an event has occurred, unnecessary real-time video will be recorded when event recording is performed. As a result, the storage capacity of the storage medium inserted into the second storage unit 230 becomes full, and there is a possibility that the images of the collision, etc. that are really necessary will not be retained. Furthermore, an icon for specifying the location of the point where the false detection has occurred is displayed on the map, making the map difficult to see.

Therefore, in the present embodiment, this is a point where it is determined that an event that should be treated as an event has occurred based on the measurement result of the acceleration sensor 170, but this determination is incorrect, and in reality, an event that should be treated as an event has occurred. Points that do not occur are recognized as "false detection certified points." Then, information specifying the position of the erroneous detection authorized point is stored in, for example, the main storage unit 190. Even if the measured value of the acceleration sensor 170 exceeds a predetermined threshold value when the vehicle passes through the erroneous detection authorized point again, it is not treated as an event occurring. Since it is not treated as an event occurring, no event recording is performed.

This prevents the storage capacity of the storage medium inserted into the second storage unit 230 from becoming full. Therefore, it becomes possible to memorize and preserve images of collisions, etc. that are really necessary.

Further, since the event is not treated as having occurred, an icon for specifying the location of the point where the event has occurred is not displayed on the map. Therefore, a new icon for specifying the location of the point where an event has occurred will not be displayed every time the user passes through an erroneously detected point, and the map can be prevented from becoming difficult to see.

Next, a description will be given of how to certify a false detection accredited point.

In this embodiment, the user can determine whether the detection of an event was an appropriate detection caused by an event such as a collision, or an erroneous detection caused by an event such as passing over a step. This will be done based on the reception of

Here, the reason why the determination is made based on the reception of the user's operation is that it is necessary to avoid making a mistake in determining whether or not it is an authorized point for safety reasons. This is because, if a mistaken judgment is made and a point is designated as a false detection recognition point, if an accident occurs at that false detection recognition point, the event will not be detected and event recording will not be possible. It is from.

In order to avoid such a misjudgment, in this embodiment, instead of automatically determining whether or not the integrated device 1000 is a false detection authorized point based on a predetermined standard, such automatic determination is performed. The false detection certification point is certified based on the user's judgment, which is considered to be more reliable than the above.

Next, the process when an erroneously detected authorized point is actually authorized will be described with reference to the flowchart of FIG. 6.

First, it is assumed that a car equipped with the integrated device 1000 passes through a point with a difference in level while the recognition operation for the false detection recognition point has not been accepted (No in step A1). Then, the first control unit 100 determines that an event has occurred because the measured value of the acceleration sensor 170 exceeds a predetermined threshold, as described above in the section <Determination of occurrence of event> (Yes in step A2). ). It is assumed that the point where this difference in level exists is not certified as a false detection certified point (No in step A3).

Then, processing associated with event detection is executed (step A4).

As a process associated with event detection, the first control section 100 first issues an instruction to the second control section 200 to perform event recording. In response to this instruction, the second control unit 200 executes event recording. Specifically, two video files related to this event, the date and time when the event occurred, and location information that specifies the location where the two video files were captured are linked, and this pair and this event are linked. An identifier for identification is stored in the second storage unit 230. Further, a message indicating that an event has occurred is displayed as a pop-up on the touch panel 110, such as i3 shown in FIG. Furthermore, the first control unit 100 associates location information for specifying the location where the event occurred, the level of the event that occurred, and the date and time that the event occurred to form a pair, and identifies this pair and the current event. The identifier is stored in the main storage unit 190.

In other words, even if a point has a step that should be a false detection recognition point, if it has not yet been recognized as a false detection recognition point, the recording process, which is the process associated with event detection, will be carried out as usual. , screen display processing and storage processing of position information, etc. are executed.

However, if a collision has not actually occurred and the user has not applied sudden braking or other operations to avoid an accident, the user can immediately determine that the detection of such an event is a false detection. .

Further, even if it is not possible to make a determination on the spot, the user can later determine that the detection of such an event is an erroneous detection by referring to real-time video recorded by event recording. Further, even if it cannot be determined by detecting an event once, the user can determine that the detection of an event at such a point is an erroneous detection because the event is detected every time the user passes through that point.

In this way, when the user determines that there is a false detection, the user performs an operation to certify that the point where the event was detected is a false detection authorized point. Then, the integrated device 1000 accepts this user's operation using the touch panel 110 or the buttons 140 (Yes in step A1).

When the operation is accepted, the content of the accepted operation is input to the first control unit 100. The first control unit 100, which has received the operation details, performs a process to identify the point where the event was detected as a point where false detection occurs, that is, a false detection authorized point (step A5). Specifically, the date and time when an event occurred at a certified false detection point and the location information that identifies the location of the certified false detection point are linked together to form a set, and an identifier for identifying this set and this certified false detection point is used as the main link. It is stored in the storage unit 190.

After that, the first control unit 100 determines that even if the measured value of the acceleration sensor 170 exceeds a predetermined threshold (Yes in step A2), if it is a certified false detection point (Yes in step A3). ), the event is treated as not occurring. Therefore, even if the measured value of the acceleration sensor 170 exceeds a predetermined threshold value, the process does not proceed to step A4. That is, processing associated with event detection, such as recording processing, screen display processing, and storage processing of position information, etc., is not executed.

Thereafter, monitoring of A1 and A2 is continued until an operation is performed to certify the erroneous detection authorized point for another point or a new event is detected (No in step A1 and No in step A2).

As described above, by performing the processing with reference to FIG. 6, it is possible to certify an erroneous detection accredited point.

At the false detection certified point, even if the acceleration value exceeds the threshold, the event is treated as not having occurred, and the processing associated with event detection is recording processing, screen display processing, and storage of position information, etc. No processing is performed.

This prevents the storage capacity of the storage medium inserted into the second storage unit 230 from becoming full. Therefore, it is possible to memorize and preserve images of collisions and the like that are really necessary.

Further, since the event is not treated as having occurred, an icon for specifying the location of the point where the event has occurred is not displayed on the map. As a result, a new icon to identify the location of the point where the event occurred will no longer be displayed each time you pass a false detection certified point, preventing the map from becoming difficult to read. be effective.

On the other hand, if the acceleration value exceeds the threshold at a point other than the false detection certified point, the event is treated as not having occurred, and the processing associated with event detection, such as recording processing and screen display processing, is performed. and performs storage processing of location information, etc.

Therefore, if an accident or the like actually occurs, event recording can be performed. In relation to this, as mentioned above, we are preventing event recording at the points recognized as false detections, so that when an accident actually occurs, the storage capacity of the storage medium is already full. This has the effect of making it possible to prevent such situations.

Additionally, if an accident actually occurs, an icon will be displayed to identify the location of the accident, making it possible to identify the location where the accident occurred. In connection with this, since the icon of the erroneous detection certified point is not displayed, it is possible to easily visually recognize the icon for specifying the position of the point where an accident or the like has occurred.

The basic contents of the certification of false detection certification points have been explained above. Below, a modification related to the erroneously detected authorized point will be described.

As explained in the <Determination of event occurrence> section above, in order to determine that an event has occurred, the acceleration measured by the acceleration sensor 170, which is measurement information that changes as the vehicle moves, and a predetermined However, instead of only one threshold value, a plurality of threshold values are provided in stages.

Therefore, it is conceivable to use these plurality of threshold values also for the recognition of false detection recognition points.

For example, it is assumed that a point exceeding a level 1 threshold, which is the most sensitive level threshold, is set as a false detection certified point. In this case, as explained in Step A3 above, from now on, even if the occurrence of an event is detected when passing through a false detection certified point, this is treated as a false detection and the event is treated as not occurring. (Yes in step A3).

However, it is possible to modify this. Specifically, if the level 1 threshold, which is the most sensitive stage threshold, is exceeded when passing through this false detection certification point, it is considered a false detection, but it is a stage less sensitive than level 1. If the threshold of level 2 or higher, which is the threshold of

The reason for doing this will be explained. If there is a step with a certain level of drop, a certain amount of impact will occur each time the vehicle passes over that level. Therefore, in this embodiment, that point is certified as a false detection certified point, and thereafter, it is treated as if no event has occurred at the false detection certified point.

However, if an impact larger than the impact that would have been caused by the drop of the step occurs when passing through the step, the impact is considered to have occurred regardless of the step. In other words, it is thought that the impact was caused by an accident that was not related to the difference in level. In such a case, even if the location is a recognized false detection point, event recording should be performed and video data before and after the occurrence of the accident should be stored.

Therefore, as mentioned above, if, for example, a point that exceeds the level 1 threshold is designated as a false detection point, if it exceeds the threshold of level 2 or higher, which is a less sensitive level, it is not a false detection, but an actual point. It is treated as if an event has occurred, and processing associated with event detection is executed (step A4).

By transforming in this way, if an accident, etc. actually occurs at the false detection certified point, it will be possible to record the event and store the video data before and after the accident, etc. This effect is achieved.

On the other hand, if only the same degree of impact occurs each time at the false detection certified point, processing such as storing video data before and after the occurrence of an accident will not be performed, so unnecessary video data will be stored. This has the effect of making it possible to prevent this.

In addition, in the above explanation, when a point that exceeds the threshold of level 1 is set as a false detection certified point, processing associated with event detection is executed when the threshold of level 2 or higher, which is a less sensitive level, is exceeded. This is just one example. In addition, if a point that exceeds the level 2 threshold is designated as a false detection certified point, processing associated with event detection will be executed when the point exceeds the threshold of level 3 or higher, which is a less sensitive level. Good too.

In addition, if a point that exceeds the level 1 threshold is designated as a false detection certified point, the process associated with event detection will not be executed not only when the level 1 threshold is exceeded but also when the level 2 threshold is exceeded. It is also conceivable to execute processing associated with event detection when a threshold value is exceeded. In other words, a configuration may be considered in which the processing associated with event detection is not executed unless the level is one level higher, but two or more levels apart. This is because even if the step is the same, if the passing speed is different, the magnitude of the impact will change, so the processing associated with event detection is not executed not only at the same level but also at one level higher. That is what it is. By doing so, in a case where the threshold value of the next higher level is also exceeded due to the same level difference, there is no need to perform the certification process of the erroneously detected certification point again.

However, in this case, if an accident occurs with an impact that exceeds the threshold of the next higher level, the processing associated with event detection will be executed even though the accident has occurred. It is also conceivable that video data from an accident or the like may not be stored. Therefore, in consideration of the need to reliably store video data in the event of an accident, etc., it is preferable not to have a configuration in which processing associated with event detection is not executed unless the levels are two or more apart. Then, after setting the point where the level 1 threshold is exceeded when passing a step as a false detection recognition point, if the next time the level 2 threshold is exceeded due to a difference in passing speed at that step, , it is preferable to accept the user's operation to certify the erroneously detected accredited point again.

Further, as another modification, if at least the condition of the highest threshold value is satisfied, it is preferable that the process associated with event detection is always executed even if it is an erroneous detection authorized point. For example, if there is a threshold up to level 5, if the threshold of level 5 is exceeded, the process associated with event detection will be executed without fail even if it is a false detection authorized point. This makes it possible to prevent a situation in which processing associated with event detection is not executed even though the condition with the highest threshold value is satisfied, and as a result, processed video data is not stored.

When multiple thresholds are set, even if an impact that exceeds the highest threshold occurs, if that is a false positive point, processing associated with event detection may not be executed. Conceivable. However, in this case, even if an extremely large impact occurs, processing associated with event detection will not be executed. The occurrence of such a significantly large impact is considered to be caused by an accident or the like. Therefore, it is preferable to perform processing associated with event detection. Therefore, as described above, if at least the condition with the highest threshold value is satisfied, it is preferable to always execute the process associated with event detection even at a false detection authorized point.

Furthermore, as another modification, it is conceivable that the size of the erroneously detected authorized point is defined by a certain distance range. For example, when an event is detected at a certain point, it is conceivable to define a radius of several meters around that point as a false detection authorized point. By doing this, even if the point at which an impact occurs is slightly shifted depending on the passing speed even if the step is the same, this shifted point can also be treated as an erroneously detected point.

It is also conceivable to define the false detection certified point not only by the distance range representing the false detection certified point but also by the passing direction when passing through the false detection certified point.

By doing so, when the vehicle enters the distance range of the erroneous detection authorized point from a certain direction, it can be determined that the user is located at the defined erroneous detection authorized point. On the other hand, if the vehicle enters the distance range of the erroneous detection authorized point from another direction, it can be determined that the defined erroneous detection authorized point is not within the range.

For example, if a person enters the distance range of an erroneous detection certified point from a certain direction, the same degree of impact will occur each time, but if a person enters the distance range of a erroneous detection certified point from another direction. is preferably defined by the passing direction when passing through the false detection authorized point in addition to the distance range representing the false detection authorized point as described above at a point where no impact occurs every time.

For example, assume that one lane of a two-lane road (temporarily assumed to be an up lane) has a level difference, and the other lane (tentatively assumed to be an outbound lane) has no level difference. In this case, when the vehicle enters the distance range of the erroneous detection recognition point from the up lane, a certain impact occurs due to passing over a step each time. Therefore, in this case, it is preferable not to perform processing associated with event detection, assuming that the erroneous detection authorization point has been passed. On the other hand, if the vehicle enters the distance range of the false detection recognition point from the down lane, there is no step, so normally no impact will occur. If a shock were to occur, it would probably be caused by an accident or the like. Therefore, in this case, it is preferable to perform processing associated with event detection, assuming that the erroneous detection authorized point has not been passed.

Therefore, in consideration of the case where it is necessary to determine whether to memorize or not depending on the passing direction, in addition to the distance range representing the false detection recognition point as described above, It is best to define it by the passing direction when doing so.

In addition, as another modification, it is preferable to perform processing to prevent the number of erroneously detected certified points from increasing too much. For example, if a predetermined period of time has elapsed since it was certified as a false detection certified point, or if the number of false detection certified points reaches a predetermined number, or in both cases, it is certified as a false detection certified point. It is conceivable to avoid treating some or all of the points where the detection has occurred as false detection authorized points.

In this way, if a predetermined period of time has elapsed since the point was certified as an erroneous detection authorized point, it may be configured such that it is not treated as an erroneous detection authorized point. By doing so, the number of erroneously detected authorized points can always be kept below a predetermined number. Moreover, this can prevent the number of erroneously detected authorized points from becoming enormous. If the number of erroneously detected points becomes enormous, a large number of erroneously detected points will be output when information for specifying the location of the erroneously detected points is output. It is preferable to prevent the number of points from becoming enormous.

In particular, if the integrated device 1000 is a device that is used continuously for a long period of time, the number of false detection certified points will increase as the period of use increases. It is better to suppress

In addition, as another modification, if no impact occurs even though the vehicle passes through an erroneous detection authorized point, it may be possible to no longer treat that point as the erroneous detection authorized point.

This makes it possible to prevent points that should no longer be treated as false detection authorized points from being treated as false detection authorized points.

For example, suppose that there is a level difference at a certain point, and an impact that exceeds a threshold value of some level occurs every time the object passes over it. In this case, as described above, this certain point is determined to be the erroneous detection authorized point. However, if the situation changes and, for example, the level difference disappears due to paving work, an impact that exceeds any level threshold will not occur even if the vehicle passes this certain point. In such a case, it is preferable not to treat this certain point as an erroneous detection authorized point. This is because even though the point was designated as a false detection certification point because it is a point where an impact that exceeds some threshold occurs every time you pass, due to changes in the situation, even if you pass, the impact that exceeds some threshold will not occur. This is because it was decided that it would not occur.

Furthermore, as another modification, it is also conceivable to determine whether the integrated device 1000, rather than the user, is the erroneous detection authorized point. However, as described above, for safety reasons, it is important to avoid mistakenly identifying a false detection authorization point when it should not be a false detection authorization point. Therefore, the explanation was given assuming that the user, not the integrated device 1000, certifies the false detection accredited point. However, if the integrated device 1000 can identify the false detection authorized point with an accuracy equal to or higher than that determined by the user, the integrated device 1000 may recognize the false detection authorized point.

As described above, the following three examples can be considered as methods for the integrated device 1000 to certify a false detection accredited point.

The first example is an example in which the acceleration of each axis of the acceleration sensor 170 is considered instead of simply using the acceleration value measured by the acceleration sensor 170. Assume that the acceleration sensor 170 can measure acceleration in three axes: the X-axis, the Y-axis, and the Z-axis. In this case, if a large impact is detected only on the Z axis (for example, the axis corresponding to the vertical direction) among the three axes, it is determined that there is a step at that point, and the point is incorrectly located. It will be certified as a detection certification point.

Next, the second example is an example in which if the same degree of impact is detected every time the vehicle passes a certain point, it is determined that there is a step, etc. there and an accident has not occurred. . It is normally unthinkable that an accident will occur every time a vehicle passes a certain point. Therefore, if the same degree of impact is detected every time the vehicle passes a certain point, it is determined that there is a step at that point, and that point is certified as a false detection certified point.

Finally, the third example is an example of pattern matching. First, a pattern of changes in acceleration of each axis of the acceleration sensor 170 when actually passing through a step is prepared in advance as test data. Then, pattern matching is performed between the pattern of changes in acceleration of each axis measured when passing a certain point and the prepared pattern. If the patterns of these changes are similar, it is determined that there is a step at that point, and that point is certified as an erroneous detection certified point.
<Display method>
Next, a display method in this embodiment will be explained. In this embodiment, the location where event recording was performed when an event occurred or the location where manual recording was performed in response to a user's operation are displayed as, for example, an icon on a map for driving guidance displayed by the car navigation system function. . Note that in the following explanation, these icons will be referred to as "event icons."

Then, when the user presses the event icon on the touch panel 110, the corresponding image data is played back. Here, the corresponding image data is captured by the function of the drive recorder. That is, in this embodiment, the car navigation function and the drive recorder function are linked.

The event icon may be of a single color, but may be of a different color depending on the level of the event, for example. By doing so, the user who refers to the event icon can not only know the location where the event occurred, but also the "level" of the event.

Furthermore, it is preferable to be able to distinguish between a position where event recording was performed because an event occurred, and a position where manual recording was performed in response to a user's operation. Therefore, the color of the event icon representing the position where manual recording was performed is set to be a different color from the color of the event icon representing the position where event recording was performed. Further, colors may be assigned, for example, according to traffic lights so that the user can intuitively recognize them.

For example, the event icon for a level 1 event, which is an event based on a slight impact, is green. Furthermore, the event icon of a level 1 event, which is an event based on an intermediate level impact, is yellow. Furthermore, the event icon of a level 5 event, which is an event based on a large impact, is red. Also, the event icon corresponding to manual recording is colored indigo.

An example of this color assignment is shown in [Table 1] below. The following explanation will be based on this assignment.

Then, the event icons assigned colors in this manner are displayed on the touch panel 110, superimposed on the map for operation guidance, as shown in FIG.

Furthermore, as described above with reference to FIG. 2, in this embodiment, the upper limit of the number of records that can be recorded for each of manual recording and event recording is determined. For example, the upper limit is 20 video files in total for manual recording and event recording, that is, 10 video files in total. When a new recording is made, the oldest one is deleted even if the user has not viewed it yet. Therefore, it is preferable to let the user know which old items are about to be deleted. Preferably, the user is encouraged to view the video before deleting it.

In addition, the user can also know which event icon corresponds to the event recording that just happened, which event icon corresponds to the manual recording that was performed, for example, three times ago. It is preferable to keep it.

Therefore, instead of simply displaying each event icon in different colors, for example, the event icons are displayed as circled numbers that include numbers in chronological order. This makes it possible for the user to know which event icons are new, which ones are old, and how many times ago the event icons are.

In order to display these event icons, the first control unit 100 uses map information stored in the main storage unit 190. In addition, when manual recording occurs, the information received from the second control unit 200 and stored in the main storage unit 190 includes information indicating that manual recording has occurred, the date and time that manual recording was performed, and the information that manual recording was performed. A combination of location information that specifies the location where the user is located is used. Furthermore, information stored in the main memory unit 190 when an event occurs, such as "location information for specifying the location where the event occurred, the level of the event that occurred, and the date and time that the event occurred, are linked and grouped." ``Things'' are used.

A specific example of displaying an event icon with these contents is shown in FIG.

Referring to FIG. 6, first, a map for operation guidance is displayed on the touch panel 110. It can be seen that i8 on the map is blue in color and is an event icon representing the position where manual recording was performed. Also, since the number is 1, it can be seen that it represents the position where manual recording was most recently performed.

Further, it can be seen that i9 on the map is yellow and is an event icon representing the position where level 3 event recording was performed. Also, since the number is 2, it can be seen that it represents the position of the event recording that was performed immediately before the manual event that was performed on the i8 on the map.

Furthermore, it can be seen that i10 on the map is an event icon that is red and represents the position where level 5 event recording was performed. Also, since the number is 3, it can be seen that it represents the position of the event recording that was performed immediately before the event recording corresponding to i9 on the map.

Furthermore, it can be seen that i11 on the map is an event icon that is green and represents the position where level 1 event recording was performed. Furthermore, since the number is 4, it can be seen that it represents the position of the event recording that was performed immediately before the event recording corresponding to i10 on the map.

Furthermore, i12 on the map is an event icon representing the current position and traveling direction of the car in which the integrated device 1000 is installed.

Referring to the information displayed in FIG. 6, the user may say, for example, ``We are approaching a location where a level 5 event occurred previously, so this time we should avoid driving in a manner that would cause an event to occur.'' It is possible to make a judgment such as, ``If you continue as is, you will not pass through the place where manual recording was previously performed.'' In other words, it becomes possible to present information useful to the user.

Further, when the user presses an event icon, the video file corresponding to the event icon is played back.

Specifically, when any event icon is pressed, a list of event icons including that event icon is displayed on, for example, the right half of the touch panel 110, as shown in i13 of FIG. For this purpose, the map is displayed on the left half, for example, as shown in i14 of FIG.

Then, the first control unit 100 determines which event icon in the event list was pressed by the user based on where on the touch panel 110 was pressed. Then, the date and time when the event recording of the event corresponding to the pressed event icon was performed, or the date and time when the manual recording corresponding to the pressed event icon was performed, is read from the main storage unit 190. Then, the read date and time is transmitted to the second control unit 200.

The second control unit 200 searches the second storage unit 230 using the received date and time as a search key. Then, the video file corresponding to the date and time is read out. Here, since two video files form a set for each manual recording and each event recording, the two video files forming this set are read out. Then, the second control unit 200 decodes these two read video files and converts them into image data. Then, the image data is transmitted to the first control section 100.

The first control unit 100 reproduces the received image data by outputting it to the touch panel 110. By referring to the reproduced image data, the user can check the state of manual recording or event recording.

Next, the history icon, which is an icon separate from the event icon, will be explained. As mentioned above, there is an upper limit to the number of video files that can be protected for manual recording and event recording, so if the number exceeds 10, for example, the video files are deleted in order from the oldest. Therefore, the event icon corresponding to the deleted video file will also be deleted.

Here, the reason for deleting the video file is to take into account the capacity of the second storage unit 230, and if possible, information about manual recordings and event recordings older than 10 will be displayed on the map. It is preferable.

In this respect, the data size of information such as occurrence position information for manual recording and event recording stored in the main storage unit 190 is small compared to the data size of the video file.

Therefore, these pieces of information are left stored in the main storage unit 190 without being deleted. Then, using this information, icons representing the occurrence positions of manual recording and event recording and the level of event recording are displayed on the map. In the following description, such icons will be referred to as "history icons" to distinguish them from event icons.

Note that the amount of data required to display the history icon is small as described above. On the other hand, if history icons are displayed for too many past manual recordings and event recordings, too many icons will be displayed on the screen, which will interfere with operation guidance.

Therefore, an upper limit is set on the number of icons to be displayed. For example, assume that there are 10 event icons and 490 history icons, for a total of 500 items.

It is also necessary to distinguish between history icons and event icons. To this end, display modes such as the shape of the history icon and the shape and size of the event icon are made to differ, for example. For example, the shapes may be different, such as round and rectangular. Alternatively, although both have the same round shape, the event icon is larger and the history icon is smaller, so that the sizes are different. In any case, each history icon is shaped and sized so that its color can be distinguished. In the following explanation, it is assumed that the history icon is displayed in a diamond shape.

Note that the information used to display the history icon is specifically information received from the second control unit 200 when manual recording occurs and stored in the main storage unit 190. A combination of the occurrence of the manual recording, the date and time when the manual recording was performed, and location information specifying the location where the manual recording was performed is used. Furthermore, information stored in the main memory unit 190 when an event occurs, such as "location information for specifying the location where the event occurred, the level of the event that occurred, and the date and time that the event occurred, are linked and grouped." ``Things'' are used.

A specific example of displaying an event icon with these contents is shown in FIG. In the specific example of FIG. 8, the video file corresponding to the event icon shown in the specific example of FIG. 6 has become outdated and has been deleted, and has been replaced with a history icon.

Referring to FIG. 8, first, a map for operation guidance is displayed on the touch panel 110. Further, i15 on the map is a history icon that is blue in color and represents the position where manual recording was performed.

Further, i16 on the map is a history icon that is yellow and represents the position where level 3 event recording was performed.

Furthermore, i17 on the map is a history icon that is red and represents the position where level 5 event recording was performed.

Furthermore, i18 on the map is a history icon that is green and represents the position where level 1 event recording was performed.

Furthermore, i19 on the map is an icon representing the current position and traveling direction of the car in which the integrated device 1000 is installed.

In this way, by displaying not only event icons but also history icons, the user can grasp locations where events frequently occur.

Normally, the event icons and history icons mentioned above are displayed on the map for operation guidance, but when an operation is received from a user to confirm the location of a certified point, for example, an erroneously detected certified point may be displayed. An icon representing the location may be displayed on the map for operation guidance. The icon representing the position of the false detection certified point is called a "false detection certified icon."

By displaying the false detection certification icon on the map in this way, it can be known in advance that a predetermined impact will occur because the vehicle will pass through the false detection certification point. Furthermore, it is good to know why video data is not stored, which is a process associated with the occurrence of an event, even though an impact has occurred.

The erroneous detection certification icon may be a single color, but may have different colors, for example, depending on the level of the threshold value that triggered the certification of the erroneous detection certification point. For example, if a point where an event occurred beyond a level 1 impact was determined to be a false detection authorized point, or if a point where an event occurred beyond a level 2 impact was determined to be a false detection authorized point. It is a good idea to make the certification icon a different color. By doing this, a user who refers to the false detection recognition icon can not only know the location of the false detection recognition point, but also the "level" threshold after which it became a false detection recognition point. This is because you can understand everything.

Further, in order to distinguish the false detection certified icon from the event icon and the history icon, it is preferable that the false detection certified icon and the event icon and the history icon have different display modes such as the shape and color of the icon.

In addition, if the occurrence of an impact that exceeds the threshold occurs at multiple points consecutively at an interval less than a predetermined time interval, and all of the multiple points are certified points, the multiple points It is preferable to set the certified points as one group, and instead of displaying a large number of icons specifying the positions of each of the plurality of certified points, icons having a shape that specifies the position of one group may be displayed.

By doing so, it is possible to prevent a large number of icons specifying the positions of a plurality of points from being displayed and making the screen difficult to view. In addition, although icons that specify the location of each of multiple points are not displayed, icons that specify the location of one group are displayed, so the user can understand that there are multiple false positive certified points at that location. It's good because it can be done.

BACKGROUND OF THE INVENTION Some roads are constructed with a series of steps in order to reduce driving speed and alert drivers of moving vehicles by generating sound and vibrations. When passing through such a road, impacts that exceed the threshold value occur continuously. However, if information for specifying each point is output for each point where an impact exceeding these thresholds has occurred, a large amount of information will be output. Therefore, by treating each of these points as one group and outputting an icon that specifies the position of one group, it is possible to prevent an unnecessary increase in the number of icons to be output. In this case, it is troublesome for the user to perform an operation to certify each of these points as a erroneous detection certifying point. Therefore, it is preferable to combine the points included in one group so that they can be certified as false detection certified points with a single operation.
<Screen transition>
Next, how the screen changes depending on the situation of the car and the user's operations will be explained with reference to the transition diagrams of FIGS. 9 to 11.

First, refer to FIG. 9. When the first control unit 100 is activated, a main menu is displayed as shown in screen S1. On the main menu screen, you can select various functions such as navigation, TV, music, pictures, and drive recorder. Among these, the functions of the navigation and drive recorder, which are the features of this embodiment, will be explained.

When the [Navi] button is selected on screen S1, the navigation function is activated and the screen changes to screen S2.

On the screen S2, as described with reference to FIGS. 6 and 8, event icons and history icons are displayed on the map for operation guidance, and operation guidance is executed with audio output. The content of this display is the content explained in the <Display method> section above. Further, the method of determining the occurrence of an event by the first control unit 100, the operation when an event occurs, etc. are the same as described in the section <Event Occurrence> described above. Here, assume that the user presses the [Shortcut] button. Here, it is assumed that "camera video" is associated with the "shortcut" button. In this case, the screen changes to S3, and real-time video, which is the video currently being captured by camera 210, is displayed on the screen. In this state, when the user presses the [End] button, the screen changes to S2 and the operation guidance is executed again.

Furthermore, when any [icon] button is pressed in the state of screen S2, processing for reproducing the video file corresponding to the pressed event icon or history icon is started. Specifically, the screen changes to S4, where a message indicating that continuous recording will be temporarily interrupted is output, and the user's selection of either the "Yes" or "No" button is accepted.

Here, the reason for temporarily suspending continuous recording is to prevent the situation where the image data being played back is overwritten if it is determined that a new event has occurred while playing the image data. This is because it becomes possible.

In addition, in cases where each image data is managed by assigning a number and making a list, and when it is determined that a new event has occurred during image data playback, the number assigned to the new image data may be changed. It is also possible to prevent a situation in which the numbers assigned to the image data being reproduced overlap. For example, if the recorded data currently being played is managed as the latest image data, and new image data is generated, after playback ends, the data will be managed as the latest data. This is because it is possible to prevent a situation in which the user is unable to do so.

Here, if the user presses the "No" button, the screen transitions to screen S2 and the operation guidance continues.

On the other hand, if the user presses the "Yes" button, the screen transitions to S5, and the event list is displayed on the right half of the screen as described with reference to FIG. Here, this time, the user desires not to play the video file corresponding to the icon selected from the event list on screen S5, but to play the video file corresponding to the icon selected on screen S2.

Therefore, the entire event list is treated as an [event item] button, and when this [event item] button is pressed for the first time, the map is moved to the coordinate value of the icon selected on screen S2. Then, when the [Event Item] button is pressed a second time, the screen changes to S6 and video playback starts.

On the screen S6, a message "Video will be played back" is displayed while processing for generating a video is performed. If the message "Video will be played back" is displayed for a length longer than the predetermined time required to perform the processing for generating the video, it is determined that the timeout has occurred and the screen transitions to screen S7. Then, on the screen S7, the video file corresponding to the icon selected on the screen S2 is played back.

Then, when the user presses the "back" button during or after shooting, the screen changes to screen S5. When the press of the [Back] button is accepted on the screen S5, the screen changes to the screen S2 and the operation guidance continues. Further, continuous recording is resumed without requiring any user operation.

Next, as described above, when any [icon] button is pressed in the state of screen S2, instead of playing the video file corresponding to the pressed icon, the user selects an icon from the event list. The following describes the operation when playing the video file corresponding to the icon selected from this event list.

When the press of the [MENU] button located at the bottom of the screen is accepted in the state of screen S2, the screen changes to screen S8, which is the menu screen of the navigation function.

After that, when the press of the [registration/edit] button is accepted in the state of screen S8, the screen changes to screen S9, which is a registration/edit menu screen.

Then, when the press of the [Event] button is accepted in the state of screen S9, the screen changes to screen S10 in FIG. 10.

On screen S10, similar to screen S4, a message indicating that continuous recording will be temporarily interrupted is output, and the user's selection of either the "Yes" or "No" button is accepted. The reason why constant recording is temporarily interrupted is as described in the explanation of screen S4.

Here, if the user presses the "No" button, the screen transitions to screen S9 in FIG. 9, which is a registration/edit menu screen.

On the other hand, if the user presses the "Yes" button, the screen transitions to S11, and the event list is displayed on the right half of the screen as described with reference to FIG. Unlike the case of screen S5, since the user has not selected an icon on screen S2, the user's selection of an icon from the event list on screen S5 is accepted.

Then, playback of the video file corresponding to the icon selected by the user is started. The subsequent processing on screen S6 and screen S7 is the same as the processing when transitioning from screen S5 to screen S6, so a detailed explanation will be omitted. In addition, in FIG. 10, when the return button is pressed on screen S7, the screen returns to screen S5, but it is also possible to return to screen S11 instead of screen S7.

The screen transitions when using the car navigation function have been explained above. Next, screen transitions when using the drive recorder function will be explained.

First, when the [Drive Recorder] button is pressed on screen S1, the screen changes to screen S12 or screen S13 shown in FIG. 11. Here, the condition for which screen to transition to is that the integrated device 1000 is not installed in a car, and the integrated device 1000 receives power from a secondary battery included in the power supply unit 310. Then, the screen changes to S12. On the other hand, if the integrated device 1000 is installed in a car and is receiving power from the car, the screen transitions to screen S13.

First, a case will be described in which the former integrated device 1000 is not installed in a car and the integrated device 1000 is receiving power from a secondary battery included in the power supply unit 310, so that the screen changes to screen S12. In this case, since there is an upper limit to the battery capacity of the secondary battery, it is necessary to suppress power consumption. Further, in this case, the user is carrying and using the integrated device 1000, and since the camera 210 is not fixed, it is difficult to effectively utilize the functions of the drive recorder. Therefore, in this embodiment, the function of the drive recorder is not operated when power is being supplied from the secondary battery. Then, in order to inform the user of this, when the screen changes to S12, a message such as "The recording/playback function of the drive recorder will not operate while the device is being driven by the built-in battery" is displayed. Then, when a predetermined period of time during which the user is considered to be able to recognize this message has elapsed, it is determined that the timeout has occurred and the screen transitions to screen S1.

Next, a case will be described in which the integrated device 1000 is installed in a car and the screen changes to S13 because the integrated device 1000 is receiving power from the car.

On the screen S13, real-time video captured by the camera 210 is played back in full-screen display. In this state, if the user presses the touch panel 110, that is, if any part of the screen is touched, the screen changes to S14.

Then, on the screen S14, an [End Application] button is displayed. When the user presses the [End Application] button, the operation of the application that implements the drive recorder function is ended, and the screen changes to screen S1. On the other hand, if a press on the screen is accepted in screen S14, the screen returns to screen S13 again, and real-time video is played back in full-screen display. In addition, on the screen S14, for example, it is preferable to display a button for changing settings, and when the button for changing settings is pressed, for example, the screen is further changed to a screen for making various settings related to the drive recorder function. .

Further, when a user operation is received while the screen S13 and the screen S14 are being displayed, this is used as an opportunity to start manual recording as described with reference to the middle part of FIG. That is, the real-time video played on screen S13 and screen S14 is used as a preview image for manual recording.

Next, with reference to FIG. 12, a description will be given of how the screen changes in response to the user's operations when certifying and canceling the certification of the erroneously detected certified point.

Here, the screen transition when a false detection recognition point is recognized is basically as explained with reference to the transition diagrams in FIGS. 9 to 11. Therefore, please refer to the transition diagrams in FIGS. 9 to 11. Descriptions of contents that overlap with those already explained will be omitted, and only contents that are different will be explained.

In screen S2, it is assumed that "display false detection certification icon" is associated with the "shortcut" button. When the [Shortcut] button is pressed, the screen S2 remains as it is without transitioning to the screen S3, but an erroneous detection certification icon is displayed on the map instead of the event icon and history icon. This allows the user to refer to the false detection certification icon. If the [Shortcut] button is pressed again in this state, the screen S2 remains, but an event icon and a history icon are displayed on the map instead of the false detection certification icon.

If any [icon] button is pressed while the false detection certification icon is displayed on the map on the screen S2, the screen will be displayed instead of the screen S4 as shown in the upper row of FIG. 12. The process moves to S21. Then, on screen S21, the user presses either the "Yes" or "No" button to confirm whether the point specified by the pressed false detection certification icon can remain as the false detection certification point. Accepts selections.

Here, if the "Yes" button is pressed, the point specified by the pressed erroneous detection authorization icon remains as the erroneous detection authorization point and the screen returns to screen S2.

On the other hand, if the [No] button is pressed, it is assumed that the point specified by the pressed false detection recognition icon is not a false detection recognition point. Specifically, the date and time when an event occurred at the false detection certified point corresponding to the point specified by the pressed false detection certified icon and the position of the false detection certified point are stored in the main storage unit 190. The set of information linking the specified location information and the identifier for specifying this false detection authorized point are deleted. Then, the screen returns to S2.

When any [icon] button is pressed while the event icon and history icon are displayed on the map on the screen S2, the screen S4 and the screen S21 are displayed as shown in the lower part of FIG. Instead, the screen transitions to screen S22. Then, on screen S22, the user presses either the "Yes" or "No" button to confirm whether or not the point specified by the pressed false detection authorization icon is to be newly designated as a false detection authorization point. Accepts selections.

Here, if the [Yes] button is pressed, the point specified by the pressed event icon or the pressed history icon is recognized as a false detection certified point. Then, the date and time when the event occurred at the false detection certified point and the position for specifying the position of the false detection certified point corresponding to the point specified by the pressed event icon or the pressed history icon are stored in the main storage unit 190. A set of linked information and an identifier for specifying this false detection authorized point are stored. Then, the screen returns to S2.

On the other hand, if the [No] button is pressed, the screen transitions to screen S4 without performing any process for recognizing the erroneously detected authorized point.

By doing so, it becomes possible to certify and cancel the erroneously detected accredited point.
<Battery control>
Next, battery control in this embodiment will be explained.

The power supply section 310 of the integrated device 1000 of this embodiment receives power from an external device via the USB terminal 320, as described with reference to FIG. Here, the external device is, for example, a car in which the integrated device 1000 is installed.

Specifically, insert one end of the cigarette plug cord into the car's cigarette lighter socket. Then, connect the other end of the cigarette plug cord to the USB terminal 320. Also, use a cigar plug cord with a converter. It is assumed that the cigar plug cord and the converter have a rated voltage of 5V and a rated current of 2A, for example.

After that, when the car engine starts, power supply from the cigarette lighter socket starts in conjunction with this. When the car engine stops, the power supply from the cigarette lighter socket also stops.

Next, with reference to FIG. 13, a detailed configuration of the power supply unit 310 will be described. Referring to FIG. 13, the power supply section 310 includes a power supply control section 311, a lithium ion battery 312, and a supercapacitor 313 (registered trademark). Further, the power supply section 310 is connected to the first control section 100 and the second control section 200. Note that among the functional blocks shown in FIG. 1, functional blocks that are not directly related to the explanation of battery control are omitted from illustration in FIG.

Note that the supercapacitor 313 corresponds to the "accumulator" of the present invention. Furthermore, the lithium ion battery 312 corresponds to the "secondary battery" of the present invention. Furthermore, a power source supplied from a car's cigarette lighter socket corresponds to the "external power source" of the present invention.

Here, the power supply control unit 311 has a function of controlling which device a voltage is applied to. The power control unit 311 is realized by, for example, a power management IC. Further, the first control section 100 may control part or all of the power supply control section 311. In FIG. 13, the signal lines through which the first control unit 100 transmits and receives signals for controlling the power supply control unit 311 are indicated by broken lines. On the other hand, lines for applying voltage are shown in solid lines in FIG.

The lithium ion battery 312 is a secondary battery that stores electricity by charging and can then be used as a battery. The lithium ion battery 312 is charged under the control of the power supply control section 311. When the integrated device 1000 is receiving power from an external device, the first control unit 100 is driven by the power supplied from the external device.

On the other hand, the first control unit 100 is driven by the power supplied by the lithium ion battery 312 when the integrated device 1000 is not receiving power from an external device. Furthermore, as mentioned above in the explanation section of <Screen Transition>, when the integrated device 1000 is not receiving power from an external device and is being driven by the power supplied by the lithium ion battery 312, the drive recorder stop the function. Since the purpose of this is to reduce power consumption, it is not only necessary to shut down the software running on the second control section 200, but also to stop the application of voltage to the second control section 200 itself. do.

The supercapacitor 313 is a power storage device, and stores power when the integrated device 1000 is receiving power from an external device.

In this regard, in this embodiment, when the integrated device 1000 is removed from the vehicle, the second control section 200 stores the information cached by itself in the second storage section 230, which is a non-volatile memory. Prevent data corruption by performing shutdown processing.

However, as described above, when the integrated device 1000 is removed from the vehicle, the application of voltage to the second control unit 200 is stopped. Therefore, the second control unit 200 uses the charge stored in the supercapacitor 313 to perform this shutdown process. Therefore, the supercapacitor 313 used has a capacity that can guarantee that the shutdown process can be performed in this manner.

Note that the information cached by the second control unit 200 is, for example, real-time video that has already been cached and has not yet been converted into a video file.

The first control unit 100 also controls the power supply. For example, the first control unit 100 includes, among other parts shown in FIG. 180 and the main storage unit 190. Further, it is also preferable that the first control unit 100 performs part or all of the control of the power supply control unit 311.

On the other hand, the second control unit 200 controls the power of the camera 210, the microphone 220, and the second storage unit 230, among other units shown in FIG.

Next, the basic idea of battery control in this embodiment will be explained. In this embodiment, the activation of the first control unit 100 and the second control unit 200 and the charging of the supercapacitor 313 and the lithium ion battery 312 are not all performed in parallel, but by controlling the timing of the activation, Do it in stages. This is to start the first control section 100 and the second control section 200 and charge the supercapacitor 313 and the lithium ion battery 312 without exceeding the rated current of the cigar plug cord.

Here, the rated current of the cigar plug cord is, for example, 2A. In this regard, it is conceivable to use a cigarette plug cord with a rated current exceeding 2A. However, as the rated current increases, it becomes necessary to make the cigarette plug cord thicker. This is because conductors such as electric wires that form the cord also have a small resistance, and there is a risk that the insulation coating will melt due to the heat generated, so as the current increases, the cord also needs to be thicker.

However, if the cord is made thicker, it becomes difficult to manage the cord, which is very inconvenient for the user who uses the integrated device 1000 in a limited space such as inside a car. Another problem is that the use of thick cords increases manufacturing costs.

Therefore, in this embodiment, as described above, instead of starting the first control unit 100 and the second control unit 200 and charging the supercapacitor 313 and the lithium ion battery 312, Perform the process in stages by controlling the timing. As a result, in this embodiment, the maximum value of the current when the integrated device 1000 is started is suppressed.

Next, with reference to the flowchart of FIG. 14 and the flowchart of FIG. 15, the power supply control process of this embodiment will be described in detail.

First, when the integrated device 1000 is in the shutdown state and connected to the car charger, the engine of the automobile is started. Along with this, supply of power to the integrated device 1000 is started (Yes in step A11).

Then, the power supply control section 311 starts applying voltage to the first control section 100. As a result, the first control unit 100 starts the startup process (step A12). Such activation processing includes, for example, processing for activating the touch panel 110 and the GPS sensor 160.

The first control unit 100 that has performed the startup process displays information on the touch panel 110. What is displayed at this time is the screen S1 shown in FIG. Then, in response to pressing the [Navi] button 140, the navigation function is executed (step A13). Further, even if the [drive recorder] button 140 is pressed, the drive recorder function is not yet executed. Therefore, a message such as "Starting the drive recorder. Please wait for a while" is displayed on the screen as shown in screen S14 shown in FIG. 16. Then, when a predetermined period of time during which the user is considered to be able to recognize this message has elapsed, it is determined that the timeout has occurred and the screen transitions to screen S1. In this manner, by first activating the first control unit 100 and displaying the information on the touch panel 110, it is possible to notify the user that the activation process is being performed.

Further, the power supply control unit 311 starts applying voltage to the supercapacitor 313. Along with this, the supercapacitor 313 starts storing electricity, and the voltage of the supercapacitor 313 increases (step A14).

Next, it is determined whether the current voltage of the supercapacitor 313 has become higher than a predetermined first voltage (step A15). Then, when the current voltage of the supercapacitor 313 becomes higher than the predetermined first voltage (Yes in step A15), the power supply control section 311 starts applying voltage to the second control section 200. Thereby, the second control unit 200 starts the startup process. This activation processing also includes processing for activating the camera 210 and microphone 220.

However, if the drive recorder function is executed, the maximum value of the current may exceed the rated current of the cigarette plug cord. Therefore, the second control unit 200 performs startup processing, but does not execute the drive recorder function yet. Therefore, even if the [drive recorder] button 140 is pressed at this point, a message like the screen S14 shown in FIG. 16 is displayed, similar to step A13, and the drive recorder function is not executed.

Next, it is determined whether the current voltage of the supercapacitor 313 has become higher than a predetermined second voltage (step A17). Here, the predetermined second voltage has a larger value than the predetermined first voltage.

Then, when the current voltage of the supercapacitor 313 becomes higher than the predetermined second voltage (Yes in step A17), it means that the supercapacitor 313 has sufficiently stored electricity, and a large amount of current is required to store the electricity in the supercapacitor 313. is no longer necessary. Therefore, when the answer is Yes in step A17, the process moves to step A18, and the second control unit 200 executes the drive recorder function (step A18). Further, the power supply control unit 311 starts applying voltage to the lithium ion battery 312. As a result, charging of the lithium ion battery 312 is started (step A19).

As described above, in this embodiment, the timing of applying voltage to each part included in the integrated device 1000 is controlled. This has the effect that the maximum value of current when the integrated device 1000 is started can be suppressed, and there is no need to make the cigar plug cord unnecessarily thick.

This point will be explained using specific values. For example, assume that 1.3 A is used when applying the voltage to the first control unit 100 in step A12. Furthermore, with the application of voltage to the supercapacitor 313 in step A14, it is assumed that, for example, 0.5 A is used at least until YES in step A15. Furthermore, it is assumed that, for example, 0.2 to 0.3 A is used when applying the voltage to the second control unit 200 in step A16. Furthermore, it is assumed that, for example, 0.35 A is used in applying the voltage to the lithium ion battery 312 in step A19.

When these currents are totaled, a total of 2.35 to 2.36 A is required, which exceeds the rated current of 2 A of the above-mentioned cigar plug cord. However, in this embodiment, by controlling the timing of applying voltage to each part included in the integrated device 1000, it becomes possible to start the integrated device 1000 without exceeding the rated current of 2A.

Next, battery control after starting up the integrated device 1000 will be described with reference to FIG. 15.

The integrated device 1000 that performs the navigation function and the drive recorder function continues to monitor whether or not the power supply from the car charger has been interrupted due to the stoppage of the automobile engine. Furthermore, monitoring is continued to determine whether the integrated device 1000 is removed from the car charger by removing the cigarette plug cord from the USB terminal 320 or by removing the cigarette plug cord from the car charger (in step A20). No and No in step A22).

Then, when the power supply from the car charger is interrupted due to the engine of the automobile being stopped (Yes in step A20), a shutdown process of the first control section 100 and the second control section 200 is performed. At this time, the shutdown processing of the first control section 100 is performed by power supply from the lithium ion battery 312, and the shutdown processing of the second control section 200 is performed by power supply from the supercapacitor 313. Then, the process returns to step A2 and waits until power is supplied again.

On the other hand, if the integrated device 1000 is removed from the car charger by removing the cigarette plug cord from the USB terminal 320 or by removing the cigarette plug cord from the car charger (Yes in step A22), the second The control unit 200 starts the shutdown process by supplying power through the supercapacitor 313. By doing so, the user cannot use the drive recorder function, but since the first control unit 100 does not specifically shut down, the user can continue to use the navigation function. In other words, the integrated device 1000 can be used as a portable navigation system. Note that the first control unit 100 continues to operate by being supplied with power from the lithium ion battery 312. In this way, since only one of the two control units can be shut down, the other control unit can continue to operate without having to perform any particular shutdown processing and restart.

Next, it is determined whether or not it will be connected to the car charger of the car again, and whether it will be connected to an external device other than the car. Here, the external device is, for example, a personal computer connected to the USB terminal 320 via a USB cable. Whether the connected device is a car charger or a personal computer can be determined based on, for example, a signal output from a USB cable. For example, a USB connector has five wires (VBus/D-/D+/ID/GND). If this ID line is short-circuited to the GND line, it can be determined that the ID line is connected to the personal computer. On the other hand, if the ID line is open (no connection), it can be determined that it is connected to the car charger.

If it is connected to a car (Yes in step A24: car), the process returns to step A2 and waits until power is supplied again.

On the other hand, if it is connected to an external device (Yes in step A24: external device), the process proceeds to step A25 and the first control unit 100 is shut down. This is because when the integrated device 1000 is connected to a personal computer, there is no need to perform navigation functions any more. Further, the output of the USB terminal 320 of the personal computer may not be able to cover the current required to drive the integrated device 1000.

After shutting down the first control unit 100, charging of the lithium ion battery 312 is started in preparation for using the integrated device 1000 as a portable navigation system again (step A26).

Thereafter, it is monitored whether it has been removed from the external device (step A27). If it is removed from the external device (Yes in step A27), the first control unit 100 starts a startup process by supplying power from the lithium-ion battery 312 in order to realize the function of the portable navigation (step A27). A28).

The first control unit 100 displays information on the touch panel 110 and executes a navigation function.

As described above with reference to FIG. 15, in this embodiment, when the car engine stops and the power supply from the car charger is interrupted, when the car is removed from the car charger, and when it is connected to an external device, In each case, it is possible to drive or shut down the first control section 100 and the second control section 200 as appropriate.
<Car navigation>
Next, the car navigation function by the first control unit 100 will be explained in detail.The first control unit 100 uses the current position detected by the GPS sensor 160 and the traffic monitoring points stored in the main storage unit A predetermined alarm is output when the positions of the target objects such as the above are in a predetermined positional relationship. Therefore, the main memory unit 190 stores information regarding targets to be detected (target location information including longitude and latitude, target type information, etc.), information on areas where accidents occur frequently, traffic enforcement information, etc. There is traffic safety information to help you drive safely, as well as landmarks and various other useful information for driving. Each piece of information is registered by associating the specific type of information (type of target, type of traffic control, accident-prone area, name of landmark, etc.) with location information.

The distance to the target when issuing the alarm can be changed depending on the type of target. Similar to the above, examples of the warning include an audio warning using the speaker 120, a warning using the touch panel 110, and the like. In this embodiment, the integrated device 1000 realizes a car navigation function, so it has map data.

Therefore, as a basic screen, the first control unit 100 has a function of reading road network information around the current location and displaying a map around the current location on the touch panel 110. Then, a warning screen is displayed on the touch panel 110 over the currently displayed screen. While displaying a map, if the distance between the current location and the LH system, which is a type of speed measuring device that is one of the traffic monitoring points, becomes, for example, 500 meters, a warning screen is displayed. Furthermore, the first control unit 100 performs a process of outputting from the speaker 120 a warning voice indicating the type of warning and distance, such as "LH system 500 meters ahead."

On the other hand, the first control unit 100 for realizing the navigation function also operates as follows. First, the main storage unit 190 stores road network information for navigation.

The first control unit 100 has a function of reading road network information around the current location from the main storage unit 190 and displaying a map around the current location on the touch panel 110. The first control unit 100 can search for a route from one location to another using this road network information. In addition, the main storage unit 190 stores a telephone number database in which telephone numbers are associated with location information and names of residences, businesses, facilities, etc. associated with the telephone numbers, and addresses are associated with location information of the addresses. A database of stored addresses is provided. The main storage unit 190 also stores location information of traffic monitoring points such as speed measuring devices and their types.

Further, the first control unit 100 has a function of performing processing of a general navigation device. That is, a map around the current location is displayed on the touch panel 110 at any time, and a destination setting button 140 is displayed. When the first control unit 100 detects a touch on the touch panel 110 at a position corresponding to the display position of the destination setting button 140, the first control unit 100 performs a destination setting process. In the destination setting process, a destination setting menu is displayed on the touch panel 110 to prompt the user to select a destination setting method. The destination setting menu includes a telephone number search button 140 and an address search button 140 that prompt the user to select a destination setting method. If it is detected that the phone number search button 140 has been touched, a phone number input screen is displayed and the location information corresponding to the input phone number is acquired from the main storage unit 190. If it is detected that the address search button 140 has been touched, an address selection input screen is displayed, and location information corresponding to the input address is acquired from the main storage unit 190. The acquired location information is then set as destination location information, and a recommended route from the current location to the destination is determined based on the road network information stored in the main storage unit 190. As a method for calculating this recommended route, a known method such as Dijkstra's method can be used, for example.

The first control unit 100 then displays the calculated recommended route together with a surrounding map. For example, as shown in FIG. 17, a route i23 from the current position i21 to the destination i22 is displayed in a predetermined color (for example, red) as the recommended route. This is similar to a general navigation system. In the present embodiment, the first control unit 100 compares the positional information on the route i23 with the positional information of a target such as a traffic monitoring point stored in the main storage unit 190, and determines whether the target object is located on the route i23. Displays the location of traffic monitoring points, etc.

As a result, for example, as shown in FIG. 17, a balloon is displayed from a position on the road, and the type of traffic monitoring point at that position stored in the main storage unit 190 is displayed in the balloon. For example, FIG. 17A is a display example of the warning point search screen, and shows an example in which traffic monitoring points i25a to i25f are displayed. The traffic monitoring point i25a displays the letter "N" indicating the N system in a speech bubble. Traffic monitoring points i25b, i25c, and i25e display the letters "LH" indicating the LH system in a speech bubble. The traffic monitoring point i25d displays the word "loop" indicating a loop coil in a speech bubble. The traffic monitoring point i25f displays the letter "H" indicating the H system in a speech bubble. In this way, when the touch panel 1108 detects a touch on the balloon position in the simplified display state where characters are displayed in the balloon, the simple display is switched to the detailed display as shown in FIG. 4(b).

Furthermore, as shown in FIG. 4A, a traffic monitoring point type designation section i26 is displayed on the lower right side of the touch panel 110. The traffic monitoring point type designation section i26 is a section that displays a button 140 listing the types of traffic monitoring points existing on the route i23. In the example of FIG. 4(a), the "N" type button 140i27a indicating the N system of the traffic monitoring point i25a, the "LH" type button 140i27b indicating the LH system of the traffic monitoring points i25b, i25c, and i25e, and A "loop" type button 140i27c indicating the loop coil at the monitoring point i25d and an "H" type button 140i27d indicating the H system at the traffic monitoring point i25f are displayed. When the first control unit 100 detects a touch on the display unit of the type button 140 from the touch panel 1108, the first control unit 100 displays the touched type button 140 in reverse video and displays the traffic monitoring point corresponding to the touched type button 140. If the display mode is in simple display, it is switched to detailed display, and if it is in detailed display, it is switched to simple display.

The integrated device 1000 of this embodiment includes a surrounding search function as a method for setting destinations (hereinafter, also including transit points). When this nearby search function is selected and activated, the first control unit 100 extracts facilities that meet the specified conditions and are close to the current location, and draws the extraction results on the touch panel 110. do. The user can then select one of the candidates drawn on the touch panel 110 and designate it as a destination (including a stopover) by confirming it.

That is, in order to realize such a function, the main storage unit 190 of this embodiment stores information about each facility in association with its location information and information about the classification of the facility. The information regarding the classification of facilities is a plurality of types of items organized by the name of the genre that each facility matches.

In this embodiment, when any item is specified, the first control unit 100 extracts a facility that matches the specified item and is close to the current location, and transfers the extraction result to the destination. is drawn on the touch panel 110 as a candidate. The user can designate one as a destination by selecting one of the candidates drawn on the touch panel 110.

When any of the items is selected, the first control unit 100 accesses the main storage unit 190 and selects a designated facility that exists within a reference distance (for example, 10 km) from the current location. Extract items that match the item classification. Then, a predetermined number (for example, 10) of the closest facilities are drawn at corresponding locations on the map drawn on the touch panel 110, with icons (marks) indicating the facilities being superimposed. As facility information stored in the main storage unit 190, respective icons are associated and registered for each facility, and when drawing, the associated icons are read out and drawn at a predetermined position on the touch panel 110.

Note that, if the current location exists on the map drawn on the touch panel 110, the own vehicle icon representing the own vehicle is drawn superimposed on the position corresponding to the current location. Furthermore, when drawing icons of such facilities, numbers are added and displayed in order of distance from the vehicle. The number will be updated from time to time as the vehicle moves.

Then, when the user selects a desired facility, the first control unit 100 recognizes this and determines a recommended route with the facility as the destination, and draws the result superimposed on the map on the touch panel 110.

Furthermore, the first control unit 100 has a function of providing route guidance to a set destination. In other words, in response to the user's selection to start guidance, the first control unit 100 sequentially detects the own vehicle position using GPS or autonomous navigation, draws map information representing roads etc. on the touch panel 110, and navigates to the destination. Provides directions using images and audio.

The above-mentioned instruction input such as designation or selection by the user is triggered by the first control unit 100 detecting that the button 140 on which the name of an item or function is displayed or the facility icon is touched on the touch panel 110. It can be done as follows.
<Implementation example>
The integrated device 1000 described above can be implemented in electronic equipment, for example, as follows.

FIG. 18 is a six-sided view showing an example of the external appearance of an electronic device in which the integrated device 1000 is mounted. In FIG. 18, the front view is shown in the second row of the center row. Here, FIG. 18 shows a front view of the surface directly facing the touch panel 110 when the integrated device 1000 is installed. A touch panel 110 is arranged on the front of the integrated device 1000. Moreover, the buttons 140 and the like are not arranged on the bezel surrounding the touch panel 110, so that visual viewing of the touch panel 110 is not obstructed.

A left side view is shown to the left of the front view. A first storage section 180, a notification LED 130b, and a USB terminal 320 are arranged on the left side of the integrated device 1000. The first storage unit 180 is realized by an SD slot, and an SD card, which is a storage medium, is inserted into the SD slot. The notification LED 130b is an LED that indicates whether or not power is being supplied, and lights up in green, for example, while power is being supplied. A cigarette plug cord 504 is connected to the USB terminal 320, and as described in the section <Battery Control>, the integrated device 1000 receives power from the car charger via the cigarette plug cord 504. In order to clearly show the shape of the integrated device 1000, the cord portion extending from the socket of the cigarette plug cord is not shown in FIG. 17.

A right side view is shown to the right of the front view. A second storage unit 230 is arranged on the right side of the integrated device 1000. The second storage unit 230 is realized by an SD slot, and an SD card, which is a storage medium, is inserted into the SD slot.

A top view is shown above the front view. Further, on the upper surface of the integrated device 1000, a notification LED 130a, a button 140a, a button 140b, and a button 140c are arranged. The notification LED 130a is used to indicate whether or not constant recording is being performed by the integrated device 1000, and lights up in red when, for example, constant recording is not being performed. The button 140a is a button 140 for starting manual recording, and event recording is started when the button 140a is pressed. The button 140b is a button 140 for stopping or restarting continuous recording, and the continuous recording is stopped or restarted each time the button 140b is pressed. The button 140c is a button 140 for turning on or off the integrated device 1000. If the button 140c is pressed when the power is on, the integrated device 1000 is turned off. The body shape device 1000 is powered on.

The third row of the center row shows the rear view. A camera 210 and a joint section 502 are arranged on the back side of the integrated device 1000. Furthermore, an edge 501a, an edge 501b, an edge 501c, and an edge 501d are formed on the back surface of the integrated device 1000. The camera 210 unit is incorporated into the integrated device 1000 by a ball joint, and the camera 210 is movable. It is assumed that the range of motion of the camera 210 is, for example, 15 degrees in each direction. That is, if the camera 210 is located at the center, it can move upward by 15 degrees and downward by 15 degrees, for example. The joint part is a part for attaching the integrated device 1000 to a cradle for fixing the integrated device 1000. Moreover, edge 501a, edge 501b, edge 501c, and edge 501d are ridgelines formed on the back surface. Edge 501a, edge 501b, edge 501c, and edge 501d are curved so that they do not get caught in the hand of a user who carries integrated device 1000.

The bottom view is shown in the third row of the center column. A speaker slit 503 is provided on the bottom surface of the integrated device 1000. The speaker slit 503 is a slit through which the sound output from the speaker 120 of the integrated device 1000 is output. Details of the speaker slit 503 and the speaker 120 will be described later.

Here, the integrated device 1000 has four surfaces on the back surface by providing four ridge lines, edge 501a, edge 501b, edge 501c, and edge 501d, on the back surface as described above. Further, as can be seen from, for example, the bottom view, top view, left side view, and right side view, the shape has a downward slope with respect to each end of the back surface with the camera 210 as the apex.

In this regard, it is conceivable to realize the housing of the integrated device 1000 in a flat rectangular shape by making the thickness of each end portion and the camera 210 portion the same without providing such an inclination. However, if such a shape is adopted, the entire integrated device 1000 becomes large and lacks portability.

Further, the reason why the camera 210 portion is thick and the camera 210 portion becomes the apex is due to the size of the camera 210 unit that forms the camera 210. Therefore, the camera 210 portion cannot be made thinner. On the other hand, other circuits can be made thinner than the camera 210 portion. Therefore, even if the thickness of each end portion and the camera 210 portion are made equal, only wasted space will be created within the housing of the integrated device 1000. From this point of view as well, it is not necessary to make the housing of the integrated device 1000 into a flat rectangular shape.

Therefore, in this implementation example, by providing a downward slope to each end of the back surface with the camera 210 as the apex, the thickness of the back surface can be reduced. This has the effect of preventing the device from becoming unnecessarily thick and lacking in portability, and from creating wasted space within the casing.

Other features of this implementation example will also be described with reference to FIG. 19. FIG. 19(a) shows the left side of the integrated device 1000. As described with reference to FIG. 18, the USB terminal 320 for connecting the cigarette plug cord 504 is arranged on the left side of the integrated device 1000. A notch 505 is formed in the right half of the periphery of the USB terminal 320 when viewed from the left side. Here, the notch 505 when viewed from the left side is approximately vertical from top to bottom up to the height where the USB terminal 320 is provided, but it is higher than the height where the USB terminal 320 is provided. The lower part curves to the left in an arc.

Further, FIG. 19(b) shows the back side of the integrated device 1000. When viewed from the back, the notch 505 has different lengths on the left and right sides of the upper part (for example, approximately two-thirds of the whole) and the left and right lengths of the lower part (for example, approximately one-third of the whole). ing. Specifically, the left and right lengths of the lower portion are shorter.

The reason why the cutout 505 has such a shape will be explained with reference to FIG. 19(c). FIG. 19(c) is a left side view showing a state in which the cigar plug cord 504 is attached to the USB terminal 320. Referring to FIG. 19(c), a cigar plug cord 504 and a cord portion 504-1 extending from the cigar plug cord 504 are shown.

First, as explained with reference to FIG. 19(b), when viewed from the back, the notch 505 has a shorter left and right length at the bottom, which corresponds to the thickness of the cable. ing. Therefore, when viewed from the back, the cord portion 504-1 does not shift left or right and follows the shape of the notch 505. When viewed from the left side of the notch 505, the cord portion 504-1 hangs down along a shape curved to the left in an arc. In other words, when viewed from the left side of the notch 505, the curved shape to the left in an arc guides the cord portion 504-1 of the cigar plug cord 504 in a desired direction rather than causing it to hang down.

By doing so, it is possible to prevent the code portion 504-1 from moving in an unintended direction. Also, since the cord is shaped like an arc, it is possible to prevent the cord from bending at an acute angle. This makes it possible to extend the life of the cord.

Furthermore, the left and right width of the notch 505 when viewed from the back of the integrated device 1000 is such that the cigar plug cord 504 and the cord portion 504-1 are not visible to the user when the integrated device 1000 is viewed from the front. It's good to do that. This allows the user to see only the rectangular shape of the front surface of the integrated device 1000, creating a sense of unity.

Furthermore, the left and right width of the notch 505 when viewed from the back of the integrated device 1000 is such that the cigar plug cord 504 and the cord portion 504-1 are visible to the user when the integrated device 1000 is viewed from the front. good. This allows the user to confirm that the cigarette plug cord 504 is connected to the USB terminal 320.

Other features of this implementation example will also be described with reference to FIG. 20. FIG. 20 is a rear view of the integrated device 1000, and shows the shape of the integrated device 1000 with the back portion of the cover realizing the casing removed.

FIG. 20 shows a speaker unit 506, a speaker holding portion 507, and a speaker slit corresponding position 508 representing a position corresponding to the position of the speaker slit 503.

The speaker unit 506 corresponds to the speaker 120 in FIG. 1, and uses a diaphragm to generate sounds for driving guidance, warning sounds, music, and the like. Generally, a sound emitting hole is provided in a portion corresponding to the speaker unit 506 on the back side of the cover that realizes the casing of the integrated device 1000, for guiding the sound generated by the diaphragm to the outside of the cover.

However, in this implementation example, it is assumed that the integrated device 1000 is carried around, and it is conceivable that the user will see the back side. In such a case, if a sound emitting hole is provided, the aesthetic appearance of the device will be spoiled.

Therefore, in this implementation example, the speaker holding section 507 not only holds the speaker unit 506 but also surrounds the speaker unit 506. However, the lower part of the speaker unit 506 does not surround the speaker unit 506. As a result, the sound generated by the diaphragm is guided from the lower part of the speaker unit 506 to the speaker slit corresponding position 508, and finally from the speaker slit 503. This makes it possible to output sound to the outside without providing a sound emitting hole in the portion corresponding to the speaker unit 506 on the back surface of the cover that realizes the casing of the integrated device 1000. Thereby, it is possible to prevent the sound emitting hole from spoiling the aesthetic appearance.

Next, referring to FIG. 21, a diagram will be described in which the integrated device 1000 is mounted on the cradle 2000 and the pedestal 3000 in order to fix the integrated device 1000 to a dashboard or the like. In this implementation example, the cradle 2000 can be attached to and detached from the joint part 502 shown in FIG. Use it as a.

Cradle 2000 is further connected to pedestal section 3000. The pedestal part 3000 is
Support the cradle 2000 in any position. The pedestal portion 3000 is suctioned and fixed onto a dashboard or the like using a suction cup or a suction sheet provided on the bottom surface. The pedestal portion 3000 and the cradle 2000 are rotatably connected within a predetermined angular range via a connection mechanism such as a ball joint. Since it is a ball joint, the pedestal part 3000 and the cradle main body 2000 rotate relative to each other within an arbitrary angular range in three-dimensional directions, and remain at an arbitrary angular position due to frictional resistance at the joint portion. Therefore, the integrated device 1000 attached to the cradle 2000 can also be placed in any position on the dashboard.
<Modified example>
Although the embodiments and implementation examples described above are preferred embodiments of the present invention, the scope of the present invention is not limited to the above embodiments, and various changes can be made without departing from the gist of the present invention. It may also be implemented in a similar manner.

For example, in the embodiment described above, the shape of the icon displayed on the map was changed depending on the presence or absence of a video file. Additionally, the color of the icon displayed on the map was changed depending on the level of the event. Furthermore, numbers were assigned to events according to chronological order, and the order was displayed numerically. In other words, the display mode of each icon is changed depending on such conditions. Here, varying the display mode includes, for example, varying the color, shape, size, number display, etc. of the icons.

In this regard, the correspondence between how the display modes are made different and the conditions for making the display modes different is not necessarily limited to the above-described embodiment. For example, the color of the icon displayed on the map may be changed depending on the presence or absence of a video file. Further, it is preferable to make both the color and the shape different. For example, the number of icons displayed on the map may be changed depending on the level of the event. Furthermore, if there is a first condition such as the presence or absence of a video file, and a second condition such as the level of an event, the display mode may be varied depending on the condition.

For example, it is a good idea not to delete the oldest file when performing continuous recording. Although new real-time video cannot be saved, this prevents old real-time video from being deleted.

Further, it is preferable to start and stop recording at all times in conjunction with the supply of power. This makes it possible to perform constant recording without requiring any user operations.

Furthermore, in manual recording and event recording, the oldest file may not be deleted even if a new event occurs or there is a user operation. Although this will not protect new files, it will prevent previously protected files from being deleted.

Furthermore, even files that are protected by manual recording or event recording may be deleted in accordance with user operations and settings. This makes it possible to check the contents and delete files that are considered unnecessary, thereby increasing the free space in the storage unit.

Furthermore, in the list of icons such as i13, it is also possible to arrange the event icon or history icon pressed on the map at the top of the list. Furthermore, it is also possible to rearrange each event in chronological order based on the date and time when the event occurred.

Furthermore, if the first storage unit and the second storage unit 230 can use the same type of storage medium, and for example, the capacity of the storage medium used in the second storage unit 230 has reached its maximum capacity. Additionally, it may be preferable to use the storage medium in place of the storage medium used in the first storage unit 180. This makes it possible to selectively use the two storage media depending on the situation. Further, by inserting a storage medium storing a video file into the first storage unit 180 by the second control unit 200, the video file can be played back by the first control unit 100.

Furthermore, when it is determined that an event has occurred, control may be performed to prevent the execution of a function that would impede real-time video imaging. An example of a function that obstructs real-time video imaging is the audio output function of a television. By doing so, when capturing image data, the sound of the television is stopped at least after it is determined that an event has occurred, and it is possible to prevent the sound of the television from being mixed into the data to be imaged.

Furthermore, when determining that an event has occurred, event recording may not be performed even if the measured value of the acceleration sensor 170 exceeds any one of a plurality of threshold values. With this, for example, if it is frequently determined that an event has occurred based on a slight impact, the video file will not be stored even if it is determined that an event has occurred based on the slight impact. Therefore, it is possible to prevent a situation where the number of video files increases too much and the capacity of the storage medium is quickly used up. For example, depending on the type of car, road conditions, driving habits, etc., if an event is often determined to have occurred at the most sensitive threshold, if you record every time, the important recorded data will be quickly overwritten. . Therefore, in such a case, it is preferable not to store the video file even if it is determined that an event at the most sensitive threshold has occurred, for example.

Furthermore, since the camera 210 is movable, it is preferable that either or both of the incident position and direction of the incident section 211 of the camera 210 can be moved so as to be adjustable. By doing so, it becomes possible to adjust the incident position even after the vehicle-integrated device 1000 is installed. Thereby, the range to be imaged can be adjusted to correspond to the shape and installation position of the vehicle, and image data in a desired range can be captured.

Furthermore, the threshold for determining that an event has occurred can be set to a different value for each measurement axis, so that the threshold for the measurement axis corresponding to the direction of travel of the car is higher than the thresholds for other measurement axes. Good too. By doing so, it is possible to use a threshold value depending on the usage status of the integrated device 1000, and it is possible to prevent erroneously determining that an event has occurred when no event has occurred. becomes.

In this regard, depending on the usage status of the integrated device 1000, the value measured by the acceleration sensor 170 may increase in a predetermined direction regardless of the occurrence of an event. For example, when the front surface of the integrated device 1000 is the touch panel 110, when the touch panel 110 is pressed by the user, the acceleration sensor 170 measures the measurement axis corresponding to the direction from the front surface to the rear surface of the integrated device 1000. The value goes up. Since this is not related to the occurrence of an event, it is preferable not to determine that an event has occurred in such a case.

Therefore, for example, the threshold value may be set high in the measurement axis corresponding to the direction from the front surface to the rear surface of the integrated device 1000. For example, when installing the integrated device 1000 in a car, the front surface of the integrated device 1000 provided with the touch panel 110 faces the front of the user, and the rear surface of the integrated device 1000 faces the direction of travel of the vehicle. Therefore, for example, when the direction of travel of the car is the front, the measurement axis corresponding to the direction of travel of the car is the X direction (front and back), and when the direction of travel of the car is the front, the measurement axis corresponding to the left and right of the car is the Y direction (left and right). ), the measurement axis corresponding to the top and bottom of the car is the Z direction (left and right) when the car travel direction is the front, and the threshold value for the measurement axis in the X direction (front and rear) is set to be high.

This makes it possible to not determine that an event has occurred even if some impact is detected.

Furthermore, even if the measured value of the acceleration sensor 170 exceeds the threshold value, if the threshold value is exceeded during a predetermined period including the time when an operation is accepted by the touch panel 110, it is not considered that an event has occurred. It is better to do this. As described above, for example, the measurement value by the acceleration sensor 170 increases along the measurement axis corresponding to the direction from the front surface to the rear surface of the integrated device 1000. Since this is not related to the occurrence of an event, it is preferable not to determine that an event has occurred in such a case. Therefore, if the event occurs during a predetermined period including the time when the operation is accepted, it is not assumed that the event has occurred. Thereby, even if the acceleration sensor 170 measures the impact associated with the operation, it is possible to prevent an erroneous determination that an event has occurred based on this measurement. Furthermore, in such a case, it is determined that an event has occurred and the event is recorded, but for example, it may be preferable not to display a pop-up display or output a warning sound indicating that an event has occurred. This makes it possible to prevent a situation in which a warning is output even though the acceleration sensor 170 measures the impact caused by the operation and makes an erroneous determination that an event has occurred.

When a car is located near a place where an event has occurred, it is preferable to restrict at least some of the functions executed by the integrated device 1000 that is controlled by the integrated device 1000. By doing so, the user can concentrate on driving the car at the location where the previous event occurred. It is often desirable to drive with caution in areas where events have occurred in the past. For example, suppose there is a place where it is determined that an event has occurred because the driver applied the brakes suddenly to avoid a previous accident. In this case, the functions of the integrated device 1000 to be controlled are partially restricted in the vicinity of this location. For example, it is recommended to limit the audio output function of the television. By doing this, it is possible to cancel the output of TV audio that would otherwise be a nuisance to driving near a place where the user had previously applied sudden braking to avoid an accident, allowing the user to concentrate on driving the car. becomes.

Furthermore, it is preferable to output the moving speed of the car, for example, as measurement information other than the acceleration measured at the time of event occurrence. By doing this, the user will be able to prove, for example, that the speed limit was below the legal limit or that the user was driving slowly at the time the event occurred. Note that the moving speed of the automobile can be calculated, for example, by using GPS position information. It is also good to obtain the moving speed of the vehicle by using, for example, OBD (On-board diagnostics).

In the above description, it has been explained that event icons and history icons are displayed on a map that includes the current location of the car in which the integrated device 1000 is installed. In other words, it was explained that a map around the car is displayed. In addition, when performing a route search or destination search, it is preferable to display event icons and history icons for manual recordings and event recordings that occurred around the route or around the destination. This allows the user to refer to icons even for locations that do not include the current location of the vehicle.

Furthermore, it is also possible to provide travel guidance to the location of the event icon or history icon in response to the depression of the event icon or history icon. By doing this, it becomes possible to easily revisit places where accidents have occurred in the past, places where events frequently occur, or places where the user has manually recorded.

Further, the navigation information stored in the main storage unit 190 may include all information regarding the entire country at the time of shipment. Furthermore, map data etc. are provided stored in a storage medium for each region, and the user prepares a storage medium storing the necessary map data etc. and attaches it to the first storage unit 180. It may also be used. Note that the map data and the like stored in the storage medium may be transferred to the main storage unit 190 and stored therein. Alternatively, the first control unit 100 may access a storage medium and read and use it from there.

In the embodiment described above, three storage units are provided, such as the main storage unit 190, the first storage unit 180, and the second storage unit 230, but it is not necessary to provide three storage units. For example, the first control section 100 may not be provided.

In the embodiment described above, it has been explained that the software for realizing the control by the first control unit 100 is stored in the main storage unit 190, but some or all of the software is stored not in the main storage unit 190 but in the first storage unit 190. The information may also be stored in a ROM included in the control unit 100.

The threshold value may be adjustable by the user, but in view of the fact that the user generally does not know how much to adjust the threshold value, the threshold value may be fixed. This makes it possible to prevent the user from setting an inappropriate threshold.

In the above description, the icons are not only displayed in different colors, but also as circled numbers that include numbers in chronological order. At this time, the numbers may be assigned in descending order or in ascending order along the time series. In other words, the newest icon may be numbered 1, and the oldest icon may be numbered 10. Alternatively, the number of the newest icon may be 10 and the number of the oldest icon may be 1.

In the above description, the video file is played back via the first control unit 100, but it may also be output directly from the second control unit 200 to the touch panel 110. Further, the process of decoding two video files into image data may be performed by the first control unit 100 instead of the second control unit 200.

In the above description, instead of associating "camera video" with the "shortcut" button 140, it may also be possible to associate "television video" with it. The user refers to the "camera image" when installing the integrated device 1000, but it is considered that the user refers to the "TV image" after installation, so it is possible to improve usability for the user.

Further, it is preferable that the audio operation guidance continues even when the [Shortcut] button 140 is pressed and the screen changes to S3. This can prevent the inconvenience of interruption of service guidance.

Further, a button 140 for accepting an operation that triggers manual recording may be displayed on the screen, that is, on the touch panel 110. Further, it is preferable that the button 140, which is a hard key, is used instead of the button 140 displayed on the touch panel 110 to accept an operation that triggers manual recording. This eliminates the need to provide the button 140 on the touch panel 110, making it possible to prevent, for example, the real-time video displayed in full screen on the screen S13 from being partially obscured by the button 140. .

In the explanation of FIG. 14, step A4 is performed after step A3, but steps A3 and A4 may be performed simultaneously as long as the current falls within the rated current of the cigar plug cord. This makes it possible to shorten the time it takes for the second control unit 200 to start up.

Furthermore, the acceleration detected by the acceleration sensor 170 differs depending on factors such as the individual's driving style, the type of vehicle, and the roads on which the vehicle is usually driven. Therefore, in some cases, the threshold value used as a criterion for determining that an event has occurred may be too low. In this case, it may be falsely detected that an event has occurred even though no event has occurred. On the other hand, in some cases, the threshold value used as a criterion for determining that an event has occurred may be too high. In this case, there is a possibility that an erroneous detection may be made that no event has occurred even though the event has occurred.

Therefore, it is good to allow the user to modify the threshold value set at the time of shipment. Further, in this embodiment, a plurality of threshold values are provided, and the color of the icon displayed on the map is changed depending on which threshold value the acceleration detected by the acceleration sensor 170 exceeds. By doing so, the user can use the icons in different colors as a guide when individually setting the individual differences in threshold values depending on the individual's driving style, vehicle type, roads on which the user usually drives, and the like.

Furthermore, if it is considered difficult for the user to set the threshold value, it may be possible to disable the user from modifying the threshold value set at the time of shipment.

Furthermore, when inserting an SD card or the like as a storage medium into the second storage unit 230, the number of saved video data is limited depending on the storage capacity of the SD card, so all the icons displayed on the map are I can't watch the video. However, it is preferable to distinguish between the latest file in which video data is stored and older files in which video data is not stored. Distinction may be achieved by, for example, changing the shape or color of the icon. For example, the latest files may be 10.
