Description

The present invention relates to a device, a program, and the like for sending a message to a user.

Systems for supporting safe driving by drivers of moving objects such as automobiles (hereinafter, simply referred to as "cars") are being researched daily.

For example, as an example of a system for safe driving, there is a safe driving support system (DSSS: Driving Safety Support Systems) using a vehicle information and communication system (VICS (registered trademark)).

DSSS is a system for preventing accidents caused by driver's carelessness and delay in judgment. For example, when it detects that a motorcycle is coming from behind the car when turning left, it sends information to the car from the optical beacon and sends a message to the driver of the car saying "There is a motorcycle, be careful when turning left!". Alternatively, give the driver a danger notice or caution in advance, such as "Pause!"

In addition, the safety performance of the vehicle itself has been improved by the technology of Advanced Safety Vehicle (ASV), which is a vehicle equipped with a system that supports the safe driving of the driver using advanced technology.

Further, an example of a technique for supporting safe driving is described in Patent Document 1. The technique described in Patent Document 1 monitors the behavior of the own vehicle and other vehicles by radar or the like, and notifies the driver of these facts when the inter-vehicle distance is too narrow or when sudden braking occurs. By using such a technique, the driver can grasp that the behavior state of the vehicle is not appropriate.

By using the various systems and vehicles described above, it is possible to support the safe driving of the driver.

However, after all, it is humans who use those systems and cars. And human error caused by humans does not disappear so easily.

For example, even if it does not lead to a serious accident such as a contact accident, the driver may be in a situation where the driver is "sick" based on the driving by a driver or the like with poor manners.

The driver is frustrated, impatient, or angry due to factors such as the inconvenience of other drivers, the time constraints that the driver himself receives, and the stress that he receives from traffic conditions such as traffic jams. Some have inappropriate feelings.

Then, if such feelings are temporarily held, the driver's driving becomes rough and there is a high possibility that an accident or the like will occur. Therefore, it is indispensable for safe driving to work on the emotions of the driver while driving.

In this regard, Patent Document 2 describes a system that acquires user biological characteristic information such as the mental state of the user during driving and performs a hospitality operation to entertain the user based on the acquired user biological characteristic information. Have been described.

However, in the technique described in Patent Document 2, in order to estimate the mental state of the driver, it is necessary to prepare a device such as a dedicated sensor for measuring the physical information of the driver.

For example, a measuring device such as an infrared sensor for discriminating the driver's complexion, a face camera for measuring the driver's facial expression, posture and pupil diameter, and a pulse sensor for measuring the driver's heartbeat will be prepared. There is a need. In addition, it is necessary to prepare a pressure-sensitive sensor in the seat, measure the weight distribution applied to the seat by the pressure-sensitive sensor, and detect a small weight shift during driving.

However, such a dedicated device for measuring the physical condition of the user is not installed in a general car. Therefore, in order to realize the technique described in Cited Document 2, it is necessary to additionally mount a dedicated measuring device, which increases the cost. In addition, it may be difficult to add a new measuring device to a normal car due to the design of the car.

Therefore, an object of the present invention is to provide an apparatus and a program capable of working on a user's psychological state during driving without adding a dedicated measuring device for measuring a user's physical condition or the like. To do.

(1) Observation means for observing the situation where a moving object operated by the user is placed,
Control to send a message to the user to switch the psychological state that the user will have when the observation result by the observation means satisfies a predetermined condition to another psychological state. Means and
A device characterized by comprising.

In this way, it is possible to control for sending a message based on the observation result of the observation means for observing the situation of the moving object, so that the physical condition of the user is measured in order to send the message. There is no need to add a dedicated measuring device to do this. Further, in this way, it is possible to work on the user's psychological state during driving by a message for switching the psychological state that the user may have to another psychological state.

More specifically, in general technology including Cited Document 2 and the like, an infrared sensor for discriminating the complexion of a driver in order to grasp the psychological state of the user, which is a prerequisite for entertaining the user. In addition, a face camera for measuring the driver's facial expression, posture, and pupil diameter, and a dedicated measuring device such as a pulse sensor for measuring the driver's heartbeat were required. However, according to (1) above, if there is an observation means for observing the situation where the moving object is placed without requiring a dedicated device for observing the state of such a user, It is good because it is possible to work on the psychological state of the user. Here, the observing means may be realized by, for example, various sensors for observing the behavior of a moving object such as an acceleration sensor, a gyro sensor, and an obstacle sensor.

The "moving body operated by the user" may be a device on which the user gets on and travels on a road or the like. For example, a four-wheeled vehicle or a two-wheeled motorcycle, which is widely used in general, is preferable. Further, it is preferable to make the content of the message to be sent to the user different depending on whether the moving body is a four-wheeled vehicle or a two-wheeled motorcycle.

The user's "operation" may be, for example, changing the direction of the moving body by the handle or adjusting the moving speed by the accelerator and the brake.

"Observing the situation where the moving body is placed" should be to observe the situation about the behavior of the moving body. For example, if the observing means observes the moving speed of the moving body, the acceleration of the moving body, the steering angle of the moving body, and the operation status of the turn signal, the accelerator, and the brake pedal, the specific behavior of the moving body can be observed. It is good because you can grasp the situation.

In addition, when observing the situation where the moving body is placed, it is advisable to observe the situation around the moving body. For example, it is preferable to observe the inter-vehicle distance to another moving body and the interruption from another moving body so that the specific surrounding situation of the moving body can be grasped.

Further, when observing the situation where the moving body is placed, it is preferable to observe the current position of the moving body. For example, the observing means observes the current position of the moving body. Then, by comparing the observed current position with the map information, it is possible to specifically grasp the type of road on which the moving object is currently traveling.

The "observation means" for making these observations may be realized by the above-mentioned device capable of observing the situation regarding the behavior of the moving body and the situation around the moving body. For example, it may be realized by various sensors such as an acceleration sensor, a gyro sensor, and an obstacle sensor.

Further, it is preferable that the control means acquires the information observed by these various sensors via, for example, OBD (On-board diagnostics) incorporated in the moving body. Further, as these observed information, it is preferable to acquire the operation information of the direction indicator, the accelerator and the brake pedal, the steering angle information, and the vehicle speed information obtained from the OBD.

Since these various sensors and OBDs are mounted on a general automobile or a general automobile navigation system, it is preferable that it is not necessary to add a new measuring device.

Further, the observation means may be realized by a camera that captures an image of the surroundings of the moving body, and the control unit may grasp the situation around the moving body by analyzing the image captured by the camera. Further, in this case, if the camera provided in the drive recorder is used, it is not necessary to prepare a new camera.

Furthermore, the observation means is realized by a GPS sensor (Global Positioning System), and the position information acquired from the GPS sensor by the control unit is compared with the map information to grasp the type of road on which the moving body is currently operating. You may try to do it. Further, in this case, if the GPS sensor provided in the car navigation device is used, it is not necessary to newly prepare a GPS sensor.

The "predetermined condition" in the "when the observation result by the observation means satisfies the predetermined condition" is the case where the moving body is placed in a situation where the user has an inappropriate psychological state for driving. The conditions should be satisfied.

For example, it is preferable that the observation result by the observation means is the same as the observation result observed in the situation where the moving object is in a dangerous situation. For example, it is preferable that the observation result by the observation means is the vehicle speed of the moving object, and the vehicle speed exceeds the legal speed. Further, for example, it is preferable that the distance between the vehicle and the other moving body is equal to or less than a predetermined distance.

Then, when the observation result by the observation means satisfies a predetermined condition, the "psychological state that the user will have" may be an inappropriate psychological state for driving the moving body. It can be said that such an inappropriate psychological state should be changed to another psychological state when driving is continued. For example, a psychological state such as frustration, impatience, and anger.

The "other psychological state" should be an appropriate psychological state for driving a moving body. For example, it is good to have a calm psychological state without being excited.

The "message for switching to another psychological state" should be a message for controlling the driver's frustration and anger so that the driver can change his / her viewpoint and return to a calm state. For example, the message may be a message that represents the user's thoughts. For example, a message such as "It's terrible to interrupt. I have to be careful." In addition, it is advisable to use a message that sympathizes with the user's thoughts, or, for example, a message such as "I was surprised at the moment!". In addition, the message may change the viewpoint of the user's thinking. For example, a message such as "Adults, let's give way to the car coming from behind! It's easier!"

The "control for sending a message to the user" may be a control for sending the message so that the user can perceive it. For example, it is preferable to control the device such as a speaker or a display that can send a message so that the user can perceive the message.

As a control method, for example, the voice data of the message may be stored in the storage means, and the voice data may be reproduced at the time of transmission and output from the speaker to send the voice, or the storage means may store the message. It may be stored as text data, and the voice corresponding to the text data may be generated by voice synthesis to output the voice from the speaker. Further, for example, it is preferable to store the message as text data in the storage means and display the text data on the display. By doing so, the user can perceive the contents of these messages.

Further, for example, at least a part of the control may be performed by a server or the like, and the electronic device in the vehicle may be controlled to send a voice based on the information acquired from the server by communication.

Further, this "device" may be realized by a device that can be mounted on a moving body. For example, it may be realized as one function of a PND (Portable Navigation Device), an RD (Radar detector), or a drive recorder. These devices are equipped with various sensors such as acceleration sensors for realizing observation means, and speakers and displays for realizing control means, and these devices should be used to realize this device. It is good because it can be done.

In addition, a message that allows the driver to change his / her viewpoint and return to a calm state in order to control the driver's frustration and anger caused by the emotional stress generated by the dangerous act received from outside the vehicle while driving. It may be a device whose purpose is to send out.

In this regard, people have countless self-talks (soliloquy) in their normal lives. Such self-talk includes what is actually spoken and what is not spoken but is recalled in the head.

And such self-talk is naturally performed even when driving. In addition, it is considered that the content of this self-talk is very related to the subsequent driving behavior.

Specifically, a person becomes aggressive from emotional self-talk that reflexively emerges from dangerous driving behavior. For example, if you are driving a car and suddenly get interrupted by another car, a self-talk like "Don't make fun of yourself when you suddenly interrupt!" Comes to your mind and you attack. Become a target.

Then, at such a time, this device sends a message such as "What an unreasonable driving. There are strange people in the world! I'm glad I didn't have an accident." As a result, if there is a self-talk such as "That's right. I'm glad I didn't have an accident.", It won't be aggressive.

This is because the driver is aware by the message sent that the accident did not occur, even though the accident could have occurred due to a dangerous act induced by the actions of others. ..

In this way, this device may be a device that supports the driver to change the viewpoint by sending a message so as not to make the driver think of an aggressive self-talk.

(2) A plurality of the predetermined conditions are provided, and the message to be transmitted is selected according to which of the plurality of predetermined conditions the predetermined condition satisfied by the observation result is, and the observation means. A device that executes the transmission of the selected message when the observation result by the above satisfies the conditions for transmission specified for each selected message.

In this way, the message can be sent at the timing when the conditions for sending are satisfied for each message according to the observation result.

For example, it is assumed that a predetermined condition is satisfied when a moving body driven by a user suddenly interrupts the lane in which another moving body is traveling. In this case, the interruption occurs. It is not desirable to send a message immediately when it is there. This is because, in such a case, an operation such as adjusting the inter-vehicle distance is urgently required, and the user should perform this operation promptly.

If the message is sent in such a dangerous state that requires urgency, the driver may be distracted by this message, which is even more dangerous. Therefore, in such a case, it is advisable to send the message after the dangerous state ends. For example, the observing means observes the velocity of the moving object. Then, it is preferable to send a message on the condition that the speed of the moving body is stable based on the observed speed of the moving body and it can be determined that the moving body is in a safe state. As a result, it is possible to prevent the occurrence of an accident.

On the other hand, for example, when approaching a restricted area, it is advisable to promptly send a message when approaching. This has the advantageous effect of being able to immediately convey the message that should be transmitted as soon as possible.

That is, depending on the content of the predetermined condition, the message is promptly sent when the predetermined condition is satisfied, or the message is sent when the condition for sending is satisfied after the predetermined condition is satisfied. It is good because it can be set as.

(3) A device characterized in that after sending a message for switching to the other psychological state to the user, a message indicating an instruction regarding the operation of the moving body is further sent to the user.
By doing so, the user can be made to perform the operation according to the instruction.

The "message indicating an instruction regarding the operation of the moving body" may be an instruction regarding the operation of the steering wheel, the accelerator or the brake. For example, it is advisable to give instructions such as "Please slow down slowly" or "Please take a long distance between vehicles".

Further, in this way, a message for switching the psychological state of the user may be sent first, and then an instruction regarding the operation may be sent. In this regard, even if the instruction regarding the operation is sent first without doing so, it is assumed that the excited user may not calmly listen to the instruction regarding the operation. However, with this device, a message for switching the psychological state of the user is first sent, and as a result, the psychological state of the user is first switched, for example, an instruction is sent after the user is in a calm psychological state. , The user can calmly listen to the operation instructions.

(4) When the occurrence of a traffic rule violation caused by the user's operation is detected based on the observation result, a message explaining to the user what kind of operation should be performed to prevent the violation has occurred. A device characterized in that it is sent out.

By doing so, it is sufficient that the user can know what kind of operation has been performed to prevent the violation of the traffic rules.

"Detection of occurrence of traffic rule violation due to user operation" is to detect when the observation result of the observation means is in a state where it would be in violation of the traffic rule if it is this observation result. It is good to set it to. For example, when it is observed that the moving speed of the moving body exceeds the legal speed, it is preferable to detect the occurrence of the legal speed violation.

In this case, the "message explaining what kind of operation did not cause the violation" is, for example, a message such as "the accelerator was pressed too much" or "the brake should have been applied early". Good. As a result, when a traffic rule violation occurs, the user knows not only the fact that the traffic rule violation has occurred, but also how to operate the vehicle so that the violation does not occur. Therefore, the user may not cause the same operation error in the future operation.

(5) When the occurrence of a violation of the traffic rule is detected, with a message explaining what kind of operation should be performed to prevent the violation, or in place of the message, which traffic rule is violated. A device characterized by sending a message explaining whether the traffic rules have such contents.

By doing so, the user can know what kind of traffic rule the contrary traffic rule is. As a result, the user knows not only the fact that the traffic rule has been violated, but also what kind of rule the violated traffic rule is. In this respect, the traffic rules are diverse, and it is possible that the user does not completely grasp all the traffic rules, but the message from this device allows the user to grasp the traffic rules that were not fully grasped. It is good because it becomes.

(6) An apparatus characterized in that the message is transmitted when it can be determined that the moving body is in a safe state based on the observation result.

In this way, the message is not sent when the mover is in a dangerous situation, but is sent when the mover is in a safe situation. Therefore, the user can calmly perceive the message when the moving object is in a safe situation. If this is not done, the message will be sent in a situation where the mobile is in a dangerous situation and you have to concentrate on the operation, and the user will not be able to listen to the message calmly. It is good because it can be prevented.

Further, for example, a message is sent even though the mobile body is in a dangerous state, and the user pays attention to the message, so that the user's concentration is deviated from the operation of the mobile body, which is a dangerous situation. It is good because it is possible to prevent it from being lost.

"The moving body is in a safe state" may be defined as a case where the vehicle is traveling stably, for example, not during sudden braking or sudden steering. Further, the "determination based on the observation result" may be determined based on, for example, the brake pedal operation information and the steering angle information acquired from the OBD.

(7) Set a threshold value for the numerical value of the observation result of the observation means.
An apparatus characterized in that it is determined that the moving body is in a safe state when the numerical value of the observation result of the observation means becomes equal to or more than the threshold value or becomes less than the threshold value.

In this way, it may be possible to determine whether or not the moving object is in a safe state by comparing the observation result with the threshold value. The "value obtained by quantifying the observation result of the observation means" may be, for example, an acceleration value or a steering angle value of the steering wheel.

Further, "when the numerical value of the observation result of the observation means is equal to or more than the threshold value or is less than the threshold value, it is determined that the moving body is in a safe state", for example. By comparing the acceleration and steering angle with the threshold value, it is possible to determine whether the vehicle is in the middle of a sudden start or a sudden steering wheel, and the moving object is in a safe situation when it is not in such a sudden start or a sudden steering situation. It is advisable to judge that. Further, for example, when the moving body is moving in a place where the moving body should slow down, it is preferable to determine that the moving body is in a safe state when the speed of the moving body is equal to or less than the threshold value. ..

(8) A device characterized in that the psychological state that the user will have when the observation result by the observation means satisfies a predetermined condition is a psychological state that can adversely affect the operation of the moving body.

In this way, it is possible to send a message for switching the psychological state that adversely affects the operation of the moving body to another psychological state.

For example, when the user is in a frustrated or impatient psychological state, the user switches between these psychological states and sends a message that suppresses the frustration or impatience. As a result, the user can drive safely in a calm psychological state.

(9) A device characterized in that a message having a content representing the user's idea is sent as a message for switching to the other psychological state.

In this way, the message represents the user's thoughts. As a result, for example, when the user thinks "Do not drive the current car dangerously!", The message "Do not drive the current car dangerously!" Is sent as a message representing the user's idea. .. As a result, the message speaks for the user's feelings, so that the user's feelings are cleared and the user's own thoughts "Don't drive dangerously now!" And the feelings related to this are calmed down.

(10) A device characterized in that a message having contents that sympathize with the user's idea is sent as a message for switching to the other psychological state.

In this way, the message sympathizes with the user's thoughts. As a result, the user feels that he / she has empathized with and understood his / her frustrated psychological state and impatient psychological state, and the user's emotions may be calmed down. The message that you sympathize with should be, for example, a message such as "I was surprised at the moment!".

(11) A device characterized in that a message having a content that changes the viewpoint of the user is sent as a message for switching to the other psychological state.

In this way, the message changes the viewpoint that the user thinks. When the user's psychological state is frustrated or impatient, the user's point of view tends to be inflexible and short-circuited. However, according to this device, since it gives an opportunity to think from another viewpoint, it is good that the user can grasp the current situation from a flexible viewpoint. The message that changes the viewpoint should be, for example, "You, an adult, let's give way to the car coming from behind! It's easier!"

(12) A device characterized in that the message for switching to the other psychological state is a message recorded directly or indirectly by the user.

In this way, the message to be sent becomes a message recorded directly or indirectly by the user. In this respect, since this device works on the psychological state, the effective message differs depending on each user. In other words, the effective content of self-talk varies from person to person, and it is necessary to find a message that suits that person. Therefore, for example, the user may directly send the voice of the user's lover or family (wife or child) using a recording device or indirectly by requesting the family or the like to send a pre-recorded message as a message. You should do it. As a result, it is possible to send a message suitable for the user who uses the present device.

(13) A device characterized in that the message for switching to the other psychological state is a message selected by the user from a plurality of messages.

In this way, the user can select a favorite message as the message to be sent. In this respect, since this device works on the psychological state, the effective message differs depending on each user. In other words, the effective content of self-talk varies from person to person, and it is necessary to find a message that suits that person. Therefore, for example, it is advisable to prepare some patterns of voice quality and message contents so that the user can select a pattern that suits the user's own taste. As a result, it is possible to send a message suitable for the user who uses the present device.

(14) An apparatus characterized in that when the observation result by the observation means satisfies the same predetermined condition a plurality of times, the message to be transmitted each time is different.

By doing so, even if the same predetermined condition is satisfied, the content of the message to be sent may be different each time this condition is satisfied. For example, if the exact same message is repeatedly transmitted, the user may become accustomed to the message and the effect of switching the psychological state may be diminished. So, for example, a message to be sent when there is a sudden interrupt action from another mobile body at one time, and a message to be sent when there is a sudden interrupt action from another mobile body at another time. Is a different message. As a result, the user feels freshness in each message and listens to the message each time, so that it is possible to prevent the effect of switching the psychological state from becoming less effective than when the same message is sent each time. So good.

(15) The situation in which the moving body observed by the observing means is placed is any one of the operation situation from the user accepted by the moving body, the operating state of the moving body, and the peripheral situation of the moving body. Alternatively, a device characterized by being a combination of two or more.

In this way, it is possible to select or select and combine the grounds for determining the situation when performing the processing according to the observation result. As a result, the situation of the moving body can be determined with high accuracy.

For example, the operation status from the user accepted by the mobile body may be used as the basis for determining the situation. It is good because it can detect situations such as sudden steering and sudden braking prohibition violations. Further, for example, the operating status of the moving body may be used as the basis for determining the situation. It is good because it can detect situations such as no-light violations.

Further, for example, the surrounding situation of the moving body may be used as the basis for determining the situation. It is good because it can detect situations such as being caught in a traffic jam. In addition, it is advisable to combine these conditions. It is good because the judgment can be made even in a situation where the judgment cannot be made accurately under one condition.

(16) A device characterized in that the peripheral situation of the moving body is a situation based on the relationship between the moving body and another moving body.

By doing so, it is sufficient that the message can be sent based on the relationship between the moving body and other moving bodies. For example, the distance between vehicles is increased due to unintentionally approaching another preceding vehicle based on the situation where the following vehicle is approaching more than necessary, which is a so-called fanning act, or due to the frustration caused by time constraints. It's good to be able to send a message when it's near.

(17) A device characterized in that the peripheral situation of the moving body is a situation based on the place where the moving body is moving.

In this way, the message can be sent based on the place where the moving body is moving. For example, it may be possible to send a message in a situation where the moving body is in an exclusion zone and has entered.

(18) A device characterized in that the message is sent so that the user can detect the moving body even while operating the moving body.

In this way, the user can reliably perceive the message. During the operation of the moving body, for example, the driver visually refers to the front or the rear-view mirror, the steering wheel is grasped by the sense of touch to rotate the steering wheel, and the accelerator or brake is depressed.

Therefore, it is conceivable to send a message so that the user can detect it by using abilities other than the abilities of the five senses of the user used for such an operation. For example, it is preferable to send a voice message so that it can be detected by the user's hearing, which is relatively unused for the operation. At the same time, it is also possible to display a message on the display device.

(19) A program characterized in that a computer functions as the device according to any one of 1 to 18 above.

By doing so, the configurations described as (1) to (18) above can be realized by a computer.

Further, although the configuration described in any one of the above (1) to (18) may be realized by a computer, a part or all of the configurations described in each of the above (1) to (18) may be realized. May be realized by a computer in combination. That is, it is preferable to realize a configuration in which each of the components described in (1) to (18) above is arbitrarily combined without changing the gist of the present invention.

According to the present invention, it is possible to work on the psychological state of the user during driving without adding a dedicated measuring device for measuring the emotion of the user.

Further, when the button 102c is pressed while the message sending device 100 is activated and operating, the message sending device 100 transitions to the power off state.

<Inside the message sending device>
Next, each device / component inside the case 150 shown in FIG. 2 will be described. It should be noted that duplicate description will be omitted for each device / component shown in FIG. In FIG. 2, the button 102a, the button 102b, and the button 102c are collectively shown as the button 102.

First, a speaker 104 for sending a message or sending a voice for operation guidance is provided inside the case 150. The message, voice, etc. transmitted by the speaker 104 are audibly transmitted by the user through the sound emitting hole provided in the case 150.

Further, a GPS sensor 109 that receives a GPS signal and obtains the current position of the message sending device 100 is provided inside the case 150.

Further, inside the case 150, a control unit 120 including a microcomputer 121 and a non-volatile memory connected to the microcomputer 121 is provided. A microcomputer is realized by a computer that performs arithmetic processing. Further, the non-volatile memory is realized by EEPROM (Electrically Erasable Programmable Read-Only Memory).

In addition to the function of sending a message, the message sending device 100 of the present embodiment also has a function of guiding the operation of the vehicle, and these functions are stored in the control unit 120 as a program executed by the microcomputer included in the control unit 120. It is stored above and is realized by executing this by a microcomputer having the control unit 120.

The process for this update can be performed, for example, by installing an SD memory card in which additional data is stored in the slot portion 105 for the SD memory card and transferring the additional data from the SD memory card to the database 112. is there. Further, this data update can be performed by using a personal computer or other external device connected via the USB terminal 108.

<Operation when sending a message>
Next, the operation at the time of sending a message will be described with reference to the flowchart of FIG. 3 and the message information table shown in FIGS. 4-1 to 4-5.

First, when the switch 24c is pressed, the microcomputer 121 in the control unit 120 that detects such pressing performs arithmetic processing based on the program stored in the non-volatile memory 122, and each hardware in the message sending device 100 performs arithmetic processing. By controlling the wear, the operation guidance function is activated. Then, the operation guidance is continued in parallel with each process in each of the following steps (step S11).

Next, when the control unit 120 activates the message sending function in the same manner as the operation guidance function, the control unit 120 first refers to the table stored in the database 112.

Here, as shown in FIGS. 4-1 to 4-5, in the message information table, a "situation" for sending a message, a "number" assigned to identify each situation, and each situation have occurred. It is a detection condition for detecting whether or not, and a "detection condition and transmission method" which is a specific method for determining whether or not the detection condition is satisfied, and a message to be transmitted when the detection condition is satisfied. The "sending message", the "message sending timing" indicating the timing of sending the message, and the "message type" indicating the type of the message are included.

In the present embodiment, a message is sent based on the information contained in such a table. Specifically, when it can be determined that the detection condition is satisfied based on the detection method included in the table, it is assumed that a situation corresponding to the detection condition has occurred, and the situation in which the situation has occurred has occurred. The appropriate message is sent at the timing corresponding to the situation in which it occurs.

In order to perform such processing, first, the control unit 120 contains information, map information, etc. input from the drive recorder connection unit 106, the OBD connection unit 107, the GPS sensor 109, the illuminance sensor 111, etc., and the message information table. Based on the "detection condition and detection method" of the above, it is determined at a predetermined cycle whether or not any of the detection conditions is satisfied (No in step S12 and step S12).

In this regard, in the present embodiment, as shown in FIGS. 4-1 to 4-5, a plurality of situations in which a message should be sent are assumed. The message information table includes a plurality of detection conditions and detection methods corresponding to these plurality of situations. However, since the purpose of the explanation here is exclusively to explain the flow of a series of processes performed by the control unit 120, the case where the situation No. 1 occurs is explained here as an example, and other situations are described. , The next item, <Message Information Table>, will be explained in detail.

Here, the detection conditions for the situation of No. 1 will be described. First, the detection condition and the detection method for the situation of No. 1 are "Circle 1-> Follow the preceding vehicle from the image of the drive recorder" as shown in FIG. 4-1. Therefore, the control unit 120 analyzes the video of the drive recorder input via the drive recorder connection unit 106, and detects the preceding vehicle from the video. Then, the detected preceding vehicle is followed.

Next, on the condition that it is detected that the foot brake has been stepped on from the OBD information that is regularly monitored in the latest detection of a new vehicle between the circle 2 and the following preceding vehicle. , Detects sudden and forcible interruptions. " Therefore, the control unit 120 continues to analyze the image of the drive recorder and determines whether or not a new vehicle is detected between the following vehicle and the preceding vehicle. Then, if a new vehicle is detected between the following vehicle and the preceding vehicle, whether or not the foot brake has been depressed in the immediate vicinity of the detection is input via the OBD connection portion 107. Judgment is made based on the information about the behavior of.

Here, the reason for determining whether or not the foot brake has been depressed in the immediate vicinity of the detection of a new vehicle will be described. Even if there is an interruption of a new vehicle, if this is foretold by a blinker etc., the user adjusts the inter-vehicle distance etc. in advance before the interruption, so the foot brake immediately before the interruption There is no need to step on. However, in the case of such a sudden and forcible interruption without notice, the user will rush to step on the foot brake immediately before the interruption.

In other words, if the footbrake is depressed in the immediate vicinity of the detection of a new vehicle, a sudden forcible interruption occurs, and the user is in a state of frustration or impatience that is inappropriate for driving. It is thought to have a psychological state.

Therefore, in this way, a message for working on the user's psychology and switching the user's psychological state to a calm psychological state suitable for driving, with the detection condition that the foot brake is depressed immediately before the detection of the new vehicle. Is sent.

In this way, if the foot brake is depressed immediately before the detection of the new vehicle, the detection condition is satisfied (Yes in step S12). In this case, the control unit 120 proceeds to the process of the next step S13.

In step S13, the control unit 120 selects a message to be sent. The message to be sent is selected from the sent messages corresponding to the detection conditions satisfied this time. Here, the sent messages corresponding to the detection conditions satisfied this time include "I was surprised! Calm down! Calm down" and "Dangerous driving! Something in a hurry" as shown in Fig. 4-1. There are multiple messages such as "I wonder if it was!" In this case, one of the plurality of messages is randomly selected. When a message is selected from a plurality of messages in this way, a different message is sent each time even if the same detection condition is satisfied, so that the user is less likely to get bored with the message.

Next, the selected message is sent, but if the detection condition is satisfied and the message is sent immediately, the driving of the user may be adversely affected. For example, when there is a sudden forcible interruption, the user must first adjust the vehicle speed promptly and secure a sufficient inter-vehicle distance to perform maneuvering to escape from a dangerous state. Nevertheless, if a message is sent immediately when there is a sudden forcible interrupt, the user may be distracted by the message and cannot concentrate on maneuvering.

In this way, if the user is informed while dealing with the danger or at the moment of dealing with the danger, it may be dangerous in return. Therefore, in the present embodiment, a message is sent after the danger is dealt with (when the driver calms down). Is sent.

However, depending on the situation, there may be no problem or preferable to send a message immediately when the detection condition is satisfied. For example, in the case of the situation of No. 6 shown in FIG. 4-2, "The distance between vehicles has been reduced due to time constraints", a message is immediately sent to secure the distance between vehicles promptly. It is preferable to encourage what to do.

In other words, different situations have different timings for sending messages. Therefore, a message sending timing item is provided in the message information table, and a message is sent when the message sending timing is reached.

In this regard, the message sending timing can be roughly divided into the one in which the user's feelings are sent when the user's feelings are "calm" and the other without considering whether or not the user's feelings are "calm". It can be divided into two types: sending based on conditions. Therefore, in step S14, it is determined which of the above two the message sending timing corresponding to the satisfied detection condition corresponds to.

Here, if the message transmission timing corresponding to the satisfied detection condition is not "when it is calm" (No in step S14), the process proceeds to step S15. For example, when the detection condition of the situation of No. 6 shown in FIG. 4-2, "The distance between vehicles has been reduced due to time constraints" is satisfied, the message transmission timing is "when detected". Immediate notification to. " In such a case, the process proceeds to step S15.

Then, in step S15, it is determined whether or not the message transmission timing has come (step S15). Here, for example, if the message sending timing is "immediate notification when detected", the message sending timing is reached at the time of detection, so the process proceeds to step S19 (Yes in step S15). On the other hand, for example, if the message transmission timing is "send after passing through the intersection", the vehicle can pass through the intersection based on the map information stored in the database 112 and the position information measured by the GPS sensor 109. Waiting for the determination (No in step S15), and when it is determined that the vehicle has passed the intersection (Yes in step S15), the process proceeds to step S19 (Yes in step S15).

In step S19, the control unit 120 controls to send the message selected in step S13, and sends a message from the speaker 104 or the touch panel 101 based on the control (step S19).

For example, the voice data of the message is stored in the database 112, and the voice data is reproduced at the time of transmission and output from the speaker 104 to transmit the voice. Alternatively, the message is stored in the database 112 as text data, the voice corresponding to the text data is generated by voice synthesis, and the voice is output from the speaker 104. Further, for example, since the message is stored as text data in the message information table in the database 112, the text data is displayed on the touch panel 101. By doing so, the user can perceive the contents of these messages.

Here, FIG. 5 shows a display example on the touch panel 101 when the text data is displayed on the touch panel 101. At the time of normal operation guidance, as shown in the upper part of FIG. 5 as "(a) normal time", a map for operation guidance and various information are displayed on the screen. The user operates while referring to such a display. Here, when some detection condition is satisfied and the message transmission timing is reached, the text corresponding to the message is displayed in the lower part of FIG. 5 as shown as "(b) normal time". The user can perceive the content of the message by referring to the message.

On the other hand, if the message transmission timing corresponding to the detection condition satisfied in step S12 is "when it is calm" (Yes in step S14), the process proceeds to step S16. For example, the message sending timing corresponding to the situation of No. 1 is "sending when calm" as shown in FIG. 4-1. Therefore, in this case, the process proceeds to step S16.

Then, in steps S16 to S18, it is determined whether or not the user who is operating the vehicle is in a calm state after escaping the danger, based on the behavior of the vehicle operated by the user.

Specifically, the control unit 120 first confirms whether or not the value of the deceleration acceleration of the vehicle input to the OBD connection unit 107 is equal to or less than a predetermined threshold value (step S16). Here, the predetermined threshold value is a threshold value measured when the vehicle is in a safe state. That is, a value other than the deceleration acceleration measured during sudden braking is set as a predetermined threshold value.

If the value of the deceleration acceleration of the vehicle input to the OBD connection unit 107 is equal to or less than a predetermined threshold value, the process proceeds to step S17 (Yes in step S16). On the other hand, if the value of the deceleration acceleration of the vehicle input to the OBD connection portion 107 exceeds a predetermined threshold value, it is considered that the vehicle is in a dangerous situation during sudden braking, so the determination in step S16 is repeated. (No in step S16).

Next, the control unit 120 determines whether or not the steering angle of the steering wheel is within a predetermined range based on the information representing the steering angle of the steering wheel input from the OBD connection unit 107 (step S17). Here, the predetermined range is a value representing a range measured when the vehicle is in a safe state. That is, the range of the steering angle that is not the steering angle measured when the steering wheel is suddenly turned is set as the predetermined range.

If the steering angle of the steering wheel is within a predetermined range based on the information representing the steering angle of the steering wheel input from the OBD connection unit 107, the process proceeds to step S18 (Yes in step S17). On the other hand, if the steering angle of the steering wheel is not within the predetermined range, the process returns to step S16 (No in step S17).

Next, the control unit 120 determines whether or not the brake and accelerator operations are calm based on the information regarding the brake and accelerator operations input from the OBD connection unit 107 (step S18). The control unit 120 determines that the accelerator operation is calm when the accelerator opening degree input from the OBD connection unit 107 is within a predetermined range. Further, when the brake pedal is not pressed continuously for a predetermined time, it is determined that the brake operation is calm.

If it can be determined that the brake and accelerator operations are calm based on the information regarding the brake and accelerator operations input from the OBD connection unit 107, the process proceeds to step S19 (Yes in step S18). On the other hand, if it cannot be determined that the brake and accelerator operations are calm based on the information regarding the brake and accelerator operations input from the OBD connection unit 107, the process returns to step S16 (No in step S18).

Here, the case where the process proceeds to step S19 in this way means that the deceleration acceleration is equal to or less than the predetermined value, so that the vehicle is not in sudden braking (Yes in step S16), and the steering angle of the steering wheel is also within the predetermined range. Therefore, the steering wheel is not suddenly turned (Yes in step S17), and both the brake operation and the accelerator operation are calm (Yes in step S18).

Therefore, it is considered that the behavior of the vehicle operated by the user is stable and the user's feelings are calm. In other words, it is the timing of sending a message, "when it is calm".

Therefore, the control unit 120 controls to send the message selected in step S13, and the speaker 104 or the like executes the message sending in response to the control. Since the more specific content of the process in step S19 is the same as the content of the process in step S19 performed in the case of Yes in step S15 described above, the description thereof will be omitted here.

As described above with reference to FIG. 3, in the present embodiment, when it is determined that the detection condition is satisfied based on the detection method included in the message information table, a situation corresponding to the detection condition occurs. Assuming that the situation has occurred, an appropriate message is sent at the timing corresponding to the situation in which the situation has occurred.

As a result, the sent message has the effect of being able to work on the psychological state of the user during driving. Further, in the present embodiment, the above processing can be realized by using the information input via the OBD connection unit 107 and the information measured by the GPS sensor 109 and the illuminance sensor 111. Therefore, in order to send a message, it is not necessary to add a dedicated measuring device for measuring the user's emotions.
<Message information table>
Next, each situation included in the message information table will be described in more detail.

First, the situation of No. 1 is a situation in which a "sudden forcible interrupting act" has occurred.

Since the detection condition and detection method of this situation are "Maru 1 → Follow the preceding vehicle from the image of the drive recorder", the control unit 120 analyzes the image input from the drive recorder connection unit 106. , Detects the preceding vehicle from the video and follows the detected preceding vehicle. Then, "Maru 2 → Detects a new vehicle between the following vehicle and the preceding vehicle, and detects that the foot brake has been stepped on and sudden deceleration acceleration from the OBD information that is regularly monitored. The control unit 120 continues to analyze the image of the drive recorder, and a new vehicle is detected between the vehicle and the preceding vehicle that is following. It is determined whether or not it is done. Then, if a new vehicle is detected between the following vehicle and the preceding vehicle, the foot brake is stepped on in the immediate vicinity of the detection based on the information on the behavior of the foot brake input to the OBD connection portion 107. When it can be determined that the vehicle has been driven and a sudden deceleration acceleration is detected, it is determined that the detection condition is satisfied, and a sudden forcible interruption action is detected.

The message sent in this case is "I was surprised! Calm down! Calm down". In this way, by sending a message that sympathizes with the user and encourages the user to calm down, the psychological state of the user is switched to a psychological state suitable for driving.

Also, the other messages I send are "You're driving dangerously! Did you hurry!" Or "Did you hurry for something? There are various people. Let's drive carefully and calmly! " In this way, the psychological state of the user is switched to a psychological state suitable for driving by sending a message that changes the viewpoint of the user by considering the circumstances of the other party who has interrupted.

Also, the other message to be sent is "I'm scared! There are strange people in the world! It's dangerous, so stay away from the car and keep a distance!" In this way, by sending a message that represents the user's thoughts, the user's psychological state is switched to a psychological state suitable for driving.

Immediately after receiving a sudden and forcible interrupt action, it is in a dangerous state, so the message sending timing is "sending when calm".

Next, the situation of No. 2 is a situation in which "a tilt from the following vehicle" has occurred.

Since the detection condition and detection method of this situation are "Maru 1 → Always monitor the approach of the vehicle behind from the image of the back monitor of the drive recorder", the control unit 120 is input from the drive recorder connection unit 106. By analyzing the image, it is monitored whether the vehicle behind is approaching. Then, since "Maru 2 → Detects the tilt from the following vehicle on the condition that the approach of the following vehicle is detected by monitoring", the control unit 120 determines the distance between the vehicle and the vehicle behind the vehicle being monitored. When the distance is less than or equal to the distance, it is determined that the detection condition is satisfied, and the tilt from the following vehicle is detected.

The message sent in this case is "A car that seems to be in a hurry is approaching. You, an adult, let's move on to an insane car coming from behind!" In this way, the psychology of the user can be switched by sending a message that sets up the user who drives the vehicle.

Since the state of being tilted is a dangerous state, the message sending timing is "sending when calm".

Next, the situation of No. 3 is a situation in which "when I was busy with time, I was caught in a traffic jam on a highway or the like."

Since the detection condition and detection method of this situation is "Maru 1 → Detecting the approach of a vehicle in front from the image from the drive recorder", the control unit 120 analyzes the image input from the drive recorder connection unit 106. , Monitor if the vehicle in front is approaching. Then, "the vehicle speed of the own vehicle is monitored from the circle 2 → OBD information, and it is detected that the vehicle is caught in a traffic jam on the condition that the slow speed is detected." Therefore, the control unit 120 controls the vehicle speed input from the OBD connection unit 107. When the vehicle speed becomes less than or equal to a predetermined speed, it is determined that the detection condition is satisfied, and the tilt from the following vehicle is detected.

The message sent in this case is "It looks like a traffic jam! It can't be helped! Let's go without rushing!" By sending a message that calmly explains the situation to the user who drives the vehicle in this way, The user's psychology can be switched.

The other message sent in this case is "Everyone seems to be going in the same direction! In this way, the psychology of the user can be switched by sending a message that sympathizes with the feeling of "I'm sorry" of the user who drives the vehicle.

The message sending timing is "immediately sent when detected" because it is stuck in a traffic jam and has already slowed down and is not in a dangerous state.

Next, the situation of No. 4 is a situation in which "cannot enter a road with heavy traffic" has occurred.

The detection condition and detection method of this situation is "Maru 1 → Check that the vehicle is stopped at a confluence such as an intersection from the map information and the measured position information. The flow of the vehicle in front is detected by the image from the drive recorder. Therefore, the control unit 120 confirms that the vehicle is stopped at a confluence such as an intersection from the map information stored in the database 112 and the position information measured by the GPS sensor 109. In addition, the flow of the vehicle in front is detected by analyzing the video input from the drive recorder connection unit 106. Then, when the vehicle is stopped at a confluence such as an intersection and there is a flow of vehicles in front, "Maru 2 → Detects that the blinker is blinking from the OBD information, and if it is an AT vehicle, the shift position is Confirm from the OBD information that it is not "P", "R" or "N". It also confirms that the driver is stepping on the foot brake, and detects that the vehicle is waiting to enter the road and cannot enter the road, provided that the vehicle does not move for several tens of seconds in this state. Therefore, the control unit 120 is in a state where the blinker is blinking, the shift position is "D", etc., and the foot brake is depressed based on the information input from the OBD connection unit 107. When the vehicle does not move for several tens of seconds, it is determined that the detection condition is satisfied, and the tilt from the following vehicle is detected.

The messages sent in this case are "calm down and enter the flow of the car!" And "do not rush! Do not rush!". In this way, the psychology of the user can be switched by sending a message for calming the user who drives the vehicle.

The other message sent in this case is "Take a deep breath and switch your mind!". In this way, the psychology of the user can be switched by sending a message prompting the user who drives the vehicle to take a deep breath.

Since it is stopped without entering the flow and is not in a dangerous state, the message transmission timing is "immediate transmission when detected".

Next, the situation of No. 5 is a situation in which "a pedestrian or a bicycle walking in front on a narrow road cannot easily pass through without noticing this car approaching from behind".

Since the detection condition and detection method of this situation is "Maru 1 → Check from the map information and the measured position information that the road is a narrow road that is not an expressway or a national road", the control unit 120 stores it in the database 112. From the map information provided and the position information measured by the GPS sensor 109, it is confirmed that the vehicle is not a highway or a national road but a narrow road. Then, "Maru 2 → Detects a person in front from the image of the drive recorder." Therefore, the control unit 120 detects that there is a person in front by analyzing the image input from the drive recorder connection unit 106. To do. Then, "Maru 3 → Monitor the vehicle speed from the OBD information. It is detected that it is difficult to pass on the condition that the vehicle continues to run at a slow speed for several tens of seconds." Therefore, the control unit 120 inputs from the OBD connection unit 107. Based on the vehicle speed, it is determined that the detection condition is satisfied when the vehicle continues to travel at a slow speed for several tens of seconds, and it is detected that the vehicle cannot pass easily.

The messages sent in this case are "I'm in trouble! I don't want to threaten you and you'll notice it soon!", "I don't want to surprise people because cars are stronger than people!" And "Don't be surprised." I hope you notice it soon! Look back, look back! " In this way, the psychology of the user can be switched by sending a message that sympathizes with the user who drives the vehicle.

The other message sent in this case is "You are a gentle driver! Let's be kindly aware!". In this way, the user's psychology can be switched by sending a message complimenting the user who drives the vehicle.

Since it is slowing down without being able to pass through and is not in a dangerous state, the message sending timing is "immediately sent when detected".

Next, the situation of No. 6 is a situation in which "the distance between vehicles has been reduced due to frustration and impatience due to time constraints" has occurred.

Since the detection condition and detection method of this situation is "Maru 1 → Monitor the inter-vehicle distance from the image of the drive recorder to the vehicle in front", the control unit 120 analyzes the image input from the drive recorder connection unit 106. By doing so, the inter-vehicle distance to the vehicle in front is monitored. Then, since "Maru 2 → Monitor the vehicle speed from the OBD information", the control unit 120 monitors the vehicle speed input from the OBD connection unit 107. In addition, the control unit 120 "detects that the inter-vehicle distance has been reduced on the condition that the required inter-vehicle distance cannot be secured with respect to the current vehicle speed from the circle 3" is the monitoring result of the circle 1 and the circle 2. When it can be determined that the required inter-vehicle distance cannot be secured with respect to the current vehicle speed, it is determined that the detection condition is satisfied, and it is detected that the inter-vehicle distance has been reduced.

The message sent in this case is "It seems that the distance between vehicles is a little closer! It may be better to secure a safer distance. Let's not rush!" And ・ "Close! Close! Dangerous. Let's add the distance between cars! " In this way, the psychology of the user can be switched by sending a message that cares about the safety of the user who drives the vehicle.

Since it is necessary to prompt the vehicle to quickly take the distance between vehicles, the message transmission timing is "immediate transmission when detected".

In each of the situations described above, the message type is "mental", and a message with content that represents the user's thought, a message with content that sympathizes with the user's thought, and a message with content that changes the viewpoint of the user is sent. As a result, the psychological state of the user is switched from a state unsuitable for driving to a state suitable for driving.

On the other hand, the message type described below is "violation", and when the user's driving violates the traffic rules stipulated by laws and regulations, a message to that effect is sent to the user. As a result, the psychological state of the user who committed the violation in a psychological state inappropriate for driving, such as being relaxed, is switched, and the psychological state appropriate for driving is achieved by driving with the traffic rules in mind. Switch. Further, when the user does not know or forgets the traffic rule itself, it is possible to make the user recognize that the traffic rule exists.

Next, the situation of No. 7 is a situation in which a "traffic classification violation (traffic classification violation if going straight from the right turn lane or turning left)" has occurred.

The detection condition and detection method of this situation is "Circle 1-> Detects the driving lane from the map information and the measured position information, and detects the violation on the condition that the intersection did not run in the specified direction of travel." The control unit 120 detects a traveling lane from the map information and traffic rule database stored in the database 112 and the position information measured by the GPS sensor 109, and the control unit 120 detects an intersection in a designated traveling direction. If the vehicle does not run to, it is determined that the detection conditions are satisfied, and a traffic classification violation is detected.

The messages sent in this case are the message "The traffic lane is wrong." And the message "Ah, the traffic lane seems to be wrong. I'm glad I didn't have an accident. Let's be careful this time!" .. In this way, by sending a message notifying the user who drives the vehicle that the traffic rules have been violated, the user's psychological state is changed to a psychological state suitable for driving by keeping the traffic rules in mind. Switch. Further, in the latter message, since it is a message that cares for the user, it is possible to calm the psychological state of the user.

While passing through an intersection, the driver should concentrate on driving, so the message transmission timing is "send after passing through the intersection".

Next, the situation of No. 8 is a situation in which a "traffic closure / entry violation" has occurred.

The detection conditions and detection method for this situation are as follows: "Maru 1 → Map information contains information on road closures and entry prohibitions in a database, and the measured location information detects violations on the condition that the vehicle enters a no entry path. Therefore, the control unit 120 could detect that the vehicle has entered the prohibited road based on the map information and the traffic rule database stored in the database 112 and the position information measured by the GPS sensor 109. In this case, it is determined that the detection conditions are satisfied, and a road closure / entry violation is detected.

The messages sent in this case are "This road is prohibited from entering" and "This road is prohibited from entering, so let's change the route!". In this way, by sending a message notifying the user who drives the vehicle that the traffic rules have been violated, the user's psychological state is changed to a psychological state suitable for driving by keeping the traffic rules in mind. Switch. In addition, since the latter message is a message notifying the user of specific means for avoiding the violation, the user can be relieved and the user can know how to avoid the violation. Can be notified to.

In the case of a road closure / entry violation, it is necessary to change the route promptly, so the message transmission timing is "immediate notification when detected".

Next, the situation of number 9 is a situation in which a "passing violation" has occurred. The detection condition and detection method of this situation is "Maru 1-> Map information has overtaking prohibited road section information in a database", but as described above with reference to FIG. 2, the database 112 contains A traffic rules database containing such information is stored. Then, "Maru 2 → The violation is made on the condition that the measured position information and OBD information of the vehicle steering angle information and the image from the drive recorder detect the change to the lane that is prohibited from overtaking by recognizing the lane. Therefore, the control unit 120 has the information included in the traffic rule database, the position information measured by the GPS sensor 109, the steering angle information input from the OBD connection unit 107, and the image input from the drive recorder connection unit 106. When a change to a lane prohibited from overtaking is detected based on the above, it is determined that the detection conditions are satisfied, and an overtaking violation is detected.

The message sent in this case is "Overtaking is prohibited at the moment". In this way, by sending a message notifying the user who drives the vehicle that the traffic rules have been violated, the user's psychological state is changed to a psychological state suitable for driving by keeping the traffic rules in mind. Switch.

Immediately after overtaking, it is necessary to adjust the vehicle speed, etc., so the message transmission timing is "send when calm".

Next, the situation of No. 10 is a situation in which a "violation such as non-stop of railroad crossing" has occurred.

Since the detection condition and detection method of this situation is "Maru 1-> Detects passing the railroad crossing from the map information and the measured position information", the control unit 120 controls the map information and traffic rules stored in the database 112. Based on the database and the position information measured by the GPS sensor 109, it detects that the vehicle passes the railroad crossing. Then, "Maru 2 → Detects that the vehicle speed and foot brake are stepped on by OBD information and monitors the pause. A violation is detected on condition that it can be confirmed that the pause is not made." The unit 120 monitors the vehicle speed and the operation status of the foot brake input from the OBD connection unit 107, and if it can be confirmed that the vehicle is not temporarily stopped, it determines that the detection condition is satisfied and violates the railroad crossing non-stop, etc. Is detected.

The message sent in this case is "Let's pause before the railroad crossing!". In this way, by sending a message notifying the user who drives the vehicle that the traffic rules have been violated, the user's psychological state is changed to a psychological state suitable for driving by keeping the traffic rules in mind. Switch.

Since it is necessary to concentrate on driving while passing the railroad crossing, the message sending timing is "railroad crossing passing soil sending".

Next, the situation of number 11 is a situation in which a "pause violation" has occurred.

Since the detection condition and detection method of this situation is "Maru 1-> Confirm that the stop point is passed from the map information, the traffic rule database information, and the measured position information", the control unit 120 stores it in the database 112. It is confirmed that the vehicle passes the suspension point based on the map information and the information in the traffic rule database and the position information measured by the GPS sensor 109. Then, "Maru 2 → Detects that the vehicle speed and foot brake are stepped on by OBD information and monitors the pause. A violation is detected on condition that it can be confirmed that the pause is not made." The control unit 120 monitors the vehicle speed and the operation status of the foot brake input from the OBD connection unit 107, and determines that the detection condition is satisfied when it can be confirmed that the vehicle is not paused. Detect violations such as railroad crossing non-stop.

The message sent in this case is "Did not pause." In this way, by sending a message notifying the user who drives the vehicle that the traffic rules have been violated, the user's psychological state is changed to a psychological state suitable for driving by keeping the traffic rules in mind. Switch.

Since it is necessary to concentrate on driving in the vicinity of the point where the suspension is required, the message sending timing is "sending when calm".

Next, the situation number 12 is "Violation of intersection safety progress obligation (obligation to pay attention to cars and pedestrians when entering or passing an intersection and proceed at the safest speed and method possible)". It is a situation that has occurred.

Since the detection condition and detection method of this situation is "Maru 1-> Detects that a vehicle is about to enter an intersection from map information and position information", the control unit 120 controls the map information stored in the database 112. Then, based on the position information measured by the GPS sensor 109, it is detected that the vehicle is about to enter the intersection. Then, "Round 2 → Handle operation when entering an intersection, brake, accelerator, direction instruction, speed are monitored from OBD information, and violation is detected on condition that it is detected that care was not taken", so control When the unit 120 detects that the user has neglected to pay attention to the steering based on various information input from the OBD connection unit 107, it determines that the detection condition is satisfied and detects the violation of the intersection safety progress obligation. For example, when it is detected that the steering wheel is suddenly turned, the brake is suddenly stepped on, the vehicle enters an intersection at a vehicle speed higher than the specified vehicle speed without releasing the accelerator, or the direction is not indicated. It is determined that the detection conditions are satisfied.

The message to be sent in this case is different depending on the cause that satisfies the detection condition. For example, if the detection condition is satisfied because the vehicle entered the intersection at a vehicle speed higher than the predetermined vehicle speed without loosening the accelerator, the message "Let's drive at a slightly slower speed before and after the intersection" is sent. In addition, if the detection condition is satisfied because the direction instruction is neglected, the message "The direction instruction was not given when turning the intersection" is sent.

In this way, by sending a message notifying the user who drives the vehicle that the traffic rules have been violated, the user's psychological state is changed to a psychological state suitable for driving by keeping the traffic rules in mind. Switch.

While passing through an intersection, the driver should concentrate on driving, so the message transmission timing is "send after passing through the intersection".

Next, the situation number 13 said, "Sudden braking is prohibited even though sudden braking prohibition violation (sudden stop or sudden slowdown for no reason is prohibited except to prevent danger). If you do) ”is a situation that has occurred.

Since the detection condition and detection method of this situation are "monitor the brake operation information of circle 1 → OBD and measure the strength of deceleration acceleration at that time when the brake is stepped on", the control unit 120 controls the OBD. When the brake is stepped on, the strength of the deceleration acceleration at that time is measured based on the operation information of the brake and the deceleration acceleration input from the connection portion 107. Then, "Circle 2 → When the deceleration acceleration exceeds the threshold value, a violation is detected on condition that it can be detected from the image of the drive recorder that there is no obstacle in front." Therefore, the control unit 120 Is when the deceleration acceleration exceeds the threshold value, that is, when the image input from the drive recorder connection 106 is analyzed even when sudden braking is performed, and there is no obstacle in front of the vehicle. , It is determined that the detection condition is satisfied, and a sudden braking prohibition violation is detected.

The messages sent in this case are "Be careful of sudden braking!" And "There seems to be no obstacle in front." In this way, by sending a message notifying the user who drives the vehicle that he / she has driven in violation of the traffic rules, the user's psychological state is appropriate for driving with the traffic rules in mind. Switch to a psychological state.

Immediately after the sudden braking is applied, it is in a dangerous state, so the message sending timing is "sending when calm".

Next, the situation of No. 14 is "when passing through a place to be slowed down, such as a road to be slowed down specified by a road sign, an intersection where left and right cannot be seen, etc." ) ”Has occurred.

The detection condition and detection method of this situation is "Maru 1-> Map information, traffic rule database information, and measured position information. When passing a road that should be slowed down, OBD vehicle speed information is monitored and slowed down. A violation is detected on condition that the vehicle is not traveling at a speed. ”Therefore, the control unit 120 slows down based on the map information and traffic rule database stored in the database 112 and the position information measured by the GPS sensor 109. Detects that the vehicle is passing the road to be used, and nevertheless, if the vehicle speed input from the OBD connection unit 107 is not the slow speed, it is determined that the detection condition is satisfied and the slow speed violation is detected. ..

The message sent in this case is "Let's slow down at intersections and slow-moving signs that are not visible!". In this way, by sending a message notifying the user who drives the vehicle that he / she has driven in violation of the traffic rules, the user's psychological state is appropriate for driving with the traffic rules in mind. Switch to a psychological state.

Since the road to be slowed down is a place where one should concentrate on driving, the message sending timing is "sending when calm".

Next, the situation of number 15 is a situation in which a "no-light violation" has occurred.

Since the detection condition and detection method of this situation is "round 1-> detection that it is necessary to turn on the illumination from the brightness level of the sunshine sensor", the control unit 120 controls the brightness measured by the sunshine sensor 111. If the level is a predetermined threshold value, it is detected that it is necessary to turn on the lighting such as the headlight, the small light and the tail light. Then, "Maru 2 → Detects the ON / OFF of the lighting from the OBD information, and despite the brightness that it is necessary to turn on the lighting, it is a violation on condition that the vehicle has been running for a while with the lighting turned off. Therefore, the control unit 120 has been running for a while with the lighting turned off, despite the brightness that requires the lighting to be turned on, based on the lighting condition input from the OBD connection unit 107. If so, it is determined that the detection conditions are satisfied, and a no-light violation is detected.

The message sent in this case is "It's getting dark. Let's turn on the light!" Or "Can you see ahead now?". In this way, by sending a message notifying the user who drives the vehicle that he / she is acting in violation of the traffic rules, the user's psychological state is appropriate for driving with the traffic rules in mind. Switch to a psychological state. Further, in the former message, the user can be notified of a specific response method. Furthermore, the latter message can be caring for the user.

Since it is not appropriate to operate the lighting switch when the running state is not calm, the message sending timing is "sending when calm". In addition, since it is possible that the situation is calm now, the expression "sending" is used when it is calm, not when it is calm. In the case of the transmission timing of transmitting when calm as in this message, it is determined that Yes in step S14.

Next, the situation of No. 16 is a situation in which "a signal default violation (when the timing of issuing the turn signal when turning right or left is late, or when the course is changed without issuing the turn signal)" has occurred. ..

Since the detection condition and detection method of this situation are "Circle 1-> Confirm that the intersection is passed from the map information and the measured position information", the control unit 120 uses the map information stored in the database 112 and the map information. Based on the position information measured by the GPS sensor 109, it detects that the vehicle passes through the intersection. Then, "Round 2 → The steering angle from the OBD information and the information on the left and right blinkers are regularly monitored, and a violation is detected on condition that the direction indicator is not operated properly." Based on the steering angle input from the OBD connection unit 107 and the information of the left and right blinkers, the unit 120 determines that the detection condition is satisfied when the direction indicator is not properly operated, and subsequently determines that the detection condition is satisfied. Detects tilting from the car.

Specifically, the right blinker was blinked, but when it was found that the turn signal was turned left from the steering angle of the steering wheel, it was determined that the detection condition was satisfied because the turn signal was not properly operated. The message sent in this case is "Bent in the opposite direction to the turn signal."

In addition, although the right blinker is not blinking, it is determined that the turn signal has not been properly operated even when it is found that the turn signal has been turned right from the steering angle of the steering wheel.
The message to be sent in this case is "No direction instruction was given."

In addition, the blinker on the right was blinked, but it is determined that the turn signal was not properly operated even after the right turn was completed.
The message to be sent in this case is "It seems that the timing to issue the direction instruction was late."

In any case, by sending a message notifying the user who drives the vehicle that he / she has acted to violate the traffic rules, the user's psychological state is said to be driven with the traffic rules in mind. Switch to a psychological state suitable for driving.

Immediately after making a right or left turn, you should concentrate on driving, so the message transmission timing is "send when calm".

Next, the situation number 17 states, "If you violate the signal restriction (when you do not follow the timing and method of signaling specified by Cabinet Order, or when you have finished an act that requires a signal such as a left turn, a right turn, or a turn". , Even though the signal must be stopped, it continues, etc.) ”has occurred.

The detection conditions and the detection method of this situation are the same as those of the situation of No. 16 described above. That is, when the detection condition of No. 16 is satisfied, the detection condition of this situation is also satisfied at the same time. That is, when one detection condition is satisfied, two violations occur at the same time. However, the user only needs to know one point that it is necessary to properly instruct the direction of the right turn and the left turn. Therefore, in such a case, one message is sent. Therefore, the message to be sent and the message sending timing are the same as in the situation of number 17. In this way, if the same message is sent once in a row instead of being sent twice in a row, the user may not be asked to hear the same content a plurality of times in a row.

Next, the situation of No. 18 is a situation in which a "minimum speed violation (when traveling at a low speed on a highway or the like)" has occurred.

Since the detection condition and detection method of this situation are "Maru 1-> It is determined from the map information, the traffic rule database, and the measured position information that the road on which the vehicle is traveling is an expressway or the like." Determines that the vehicle is currently traveling but is on an expressway based on the map information and traffic rule database stored in the database 112 and the position information measured by the GPS sensor 109. If it can be determined, "A violation is detected on the condition that the minimum speed is less than the court speed (50 km in the case of a highway with two or more lanes) from the vehicle speed acquired from Maru 2 → OBD at regular intervals. Therefore, the control unit 120 monitors the vehicle speed input from the OBD connection unit 107, determines that the detection condition is satisfied when the vehicle speed becomes equal to or less than the legal speed predetermined speed, and tilts from the following vehicle. Is detected.

The message sent in this case is "The speed is slowing down. Watch out for cars coming from behind." In this way, by sending a message notifying the user who drives the vehicle that he / she has violated the traffic rules, the psychological state of the user is changed to the psychology appropriate for driving with the traffic rules in mind. Switch to the state. In addition, the message "Be careful of cars coming from behind" teaches the user specific points to keep in mind and makes it possible to care for the user.
Since it is necessary to increase the speed promptly, the message transmission timing is "immediate transmission when detected".

Next, the situation of number 19 is a situation in which "excessive speed" has occurred.

Since the detection condition and detection method of this situation is "Maru 1 → Determine the speed limit of the road on which the vehicle is traveling from the map information, the traffic rule database, and the measured position information", the control unit 120 has the database 112. Based on the map information and the traffic rule database stored in the vehicle and the position information measured by the GPS sensor 109, the speed limit of the road on which the vehicle is currently traveling is determined. Then, "the vehicle speed acquired from the circle 2 → OBD at regular intervals is monitored, and the violation is detected on condition that the speed limit is exceeded." Therefore, the control unit 120 determines the vehicle speed input from the OBD connection unit 107. When the vehicle speed exceeds the speed limit, it is determined that the detection condition is satisfied, and the tilt from the following vehicle is detected.

The message sent in this case is "Too fast. Please be careful." In this way, by sending a message notifying the user who drives the vehicle that he / she has violated the traffic rules, the psychological state of the user is changed to the psychology appropriate for driving with the traffic rules in mind. Switch to the state. In addition, the message "Please be careful" makes it possible to care for the user.
Since it is necessary to increase the speed promptly, the message transmission timing is "immediate transmission when detected".
Next, the situation of number 20 is a situation in which a "sudden steering wheel" has occurred.

The detection condition and detection method of this situation are as follows: "The steering angle information and acceleration information of the steering wheel acquired from the OBD at regular intervals are monitored, the steering angle exceeds the steering angle threshold angle, and the acceleration determines the steep steering threshold. A violation is detected on condition that the steering angle is exceeded. ”Therefore, the control unit 120 monitors the steering angle information and acceleration information of the steering wheel input from the OBD connection unit 107, and the steering wheel steering angle exceeds the steering angle threshold angle. When the acceleration exceeds the steep steering wheel threshold, it is determined that the detection condition is satisfied, and the steep steering wheel is detected.

The message sent in this case is "It is dangerous to turn the steering wheel suddenly. Let's slow down and then operate the steering wheel!". In this way, by sending a message notifying the user who drives the vehicle that he / she has acted in violation of the traffic rules, the user's psychological state is appropriate for driving with the traffic rules in mind. Switch to a psychological state. In addition, the message "It is dangerous to turn the steering wheel suddenly" makes it possible to care for the user.
Since it is in a dangerous state after a sudden steering wheel, the message sending timing is "sending when calm".

<Add message>
The sent message included in the above-mentioned message information table is stored in the database 112 or the non-volatile memory 122 at the time of shipment of the message sending device 100. In this respect, the message sending device 100 can newly add a message after the message sending device 100 is shipped according to the user's preference and the like.

To add a message, an SD memory card storing voice data or text data corresponding to the message is inserted into the SD memory card slot unit 105, the control unit 120 reads the data from the SD memory card, and the database 112 is added. Make a copy. Alternatively, a personal computer or the like is connected to the USB terminal 108 so that the voice data or text data corresponding to the message is copied from the personal computer to the database 112.

In addition, the number of the corresponding situation is also included in these voice data and text data. Then, when the detection condition is satisfied, the control unit 120 sends a message by using the voice data or the text data corresponding to the number of the situation in which the detection condition is satisfied.

Since the method of sending a message using the voice data or text data copied to the database 112 is the same as the sending method described above as the description of step S19, detailed description thereof will be omitted here.

In determining whether or not the detection conditions in each of the situations described above are satisfied, the information acquired from the OBD, the information measured by the GPS sensor 109, and the information measured by the illuminance sensor 111 are used. In this regard, the OBD is a system generally provided by the vehicle, the GPS sensor 109 is a sensor generally provided by the car navigation device for operation guidance, and the illuminance sensor 111 is an automatic dimming of the touch panel 101 or the like. Therefore, it is a sensor generally provided in a car navigation device. That is, the present embodiment can be realized by diverting the measured information of the car navigation device and the equipment generally provided in the vehicle for the present embodiment.

<Operation guidance function>
Next, the operation guidance function performed by the control unit 120 will be described.
The control unit 120 performs the following processing in order to realize the operation guidance function.

The control unit 120 displays a map around the current position on the touch panel 101 at any time based on the map information registered in the database 112, and displays a destination setting button. Further, when the touch panel 101 detects that the touch panel 101 presses the position corresponding to the display position of the destination setting button, the control unit 120 performs the destination setting process. In the destination setting process, the destination setting menu is displayed on the touch panel 101, and the user is prompted to select the destination setting method. The destination setting menu has a telephone number search button and an address search button that prompt the user to select a destination setting method. When it is detected that the telephone number search button is pressed, the telephone number input screen is displayed, and the location information corresponding to the input telephone number is acquired from the database 112. When it is detected that the address search button is pressed, the address selection input screen is displayed, and the location information corresponding to the input address is acquired from the database 112. Then, the acquired position information is set as the position information of the destination, and the recommended route from the current position to the destination is obtained based on the road network information stored in the database 112. As a method for calculating this recommended route, a known method such as Dijkstra's algorithm can be used.

Then, the control unit 120 displays the calculated recommended route together with the map of the surrounding area. For example, the route from the current position to the destination is displayed as a recommended route in a predetermined color (for example, red). These processes are the same as those of a general navigation system.

<Modification example>
Although the above-described embodiment is a preferred embodiment of the present invention, the scope of the present invention is not limited to the above-described embodiment, and various modifications are made without departing from the gist of the present invention. Can be implemented. For example, the above embodiment can be modified as described below.

First, in the above-mentioned <Add message> item, it was explained that voice data or text data corresponding to the message can be added.

The data to be added may be voice data recorded directly or indirectly by the user. For example, the voice data obtained by recording the voice of the user himself or the voice data recorded by the voice of the user's family may be converted into a format that can be used by the message sending device 100 and added.

The reason will be explained. Since the message sending device 100 works on the psychological state, the voice of the effective message and the content of the effective message differ depending on each user. In other words, the content of the message to work effectively on self-talk is different for each person, and it is necessary to find a message that suits that person. Therefore, for example, the user may directly send the voice of the user's lover or family (wife or child) using a recording device or indirectly by requesting the family or the like to send a pre-recorded message as a message. You should do it. As a result, it is possible to send a message suitable for the user who uses the message sending device 100.
In addition, it is advisable to add text data created by the user.

Further, the data to be added may be provided by the manufacturer of the message sending device 100 for a fee or free of charge.

For example, it is preferable to provide the voice of the voice actor of the character affiliated with the manufacturer as voice data. In this case, it is preferable to provide voice data in which the character's habits and the like are added to the message. In addition, it is preferable to provide text data in which the character's habits and the like are added to the message. In this way, a character message according to the user's taste is sent, and the user becomes more interested in the message, so that the message can be listened to or viewed in a concentrated manner. Further, since the message sending device 100 works on the psychology of the user, it may be easier for the user to accept the content of the message.

Further, it is preferable that the data to be added is not created by the manufacturer itself, but the data to be added is created by each user who has purchased the message sending device 100. By doing so, it is possible to add unexpected message data that the manufacturer does not anticipate.

For example, it is preferable to convert the additional data created by each user into a format that can be used by the message sending device 100 so that the additional data can be exchanged between the users on the Internet. In order to facilitate the exchange, for example, the manufacturer may create a site such as a bulletin board that can be viewed by each user so that the exchange can be performed on this site.

In addition, instead of exchanging one-on-one with each other, the manufacturer prepares a site for uploading additional data and a server for uploading, and each user accesses the site and creates additional data by himself / herself. Should be able to be uploaded on the server. Then, it is preferable to download and use the additional data uploaded by other users. In this way, the additional data created by one user can be used by a plurality of other users. Further, for example, the number of times each additional data has been downloaded may be displayed on the site, or the ranking may be displayed so that the additional data having a large number of downloads is ranked higher. By doing this, it is good to know which additional data is popular additional data.

Also, in order to promote the upload of additional data, it is advisable to give some incentive to the uploading user according to the number of uploads and the number of uploaded additional data downloaded to other users. For example, it is advisable to set a setting that requires a predetermined point for downloading, and to give such a predetermined point to the user who uploaded the file. In this case, if the points to be given are increased according to the number of additional data uploaded to other users, it may be an incentive to create better additional data such as a large number of downloads. In addition, cash may be used instead of the predetermined points. That is, it is preferable that the maker collects cash from the users who download it and pays the collected cash to the user who uploaded it. Further, as described above, the ranking format may provide an incentive for users aiming for higher rankings.

Further, as another modification, in the above description, when there are a plurality of messages to be sent in one situation, it has been described that which message is to be sent is randomly determined. Instead of doing this, multiple messages may be selected in sequence. In addition, the message may be selected in advance by the user. Further, the message may be selected based on the measured value related to the detection condition. For example, taking the situation of No. 1 as an example, the degree of emotional stress of the driver is estimated according to the value of the deceleration acceleration at the time when the foot brake is stepped on, and the message to be sent is sent according to the estimated degree of emotional stress. You may choose. Further, after sending the message, it is preferable to notify the user which situation has occurred depending on the detection condition.

Further, as another modification, in the above description, a series of messages are sent when the message sending timing is reached, but it is preferable to divide the message and send it, for example, by dividing it into two times. For example, after sending a message for switching the user's psychological state to another psychological state to the user, it is preferable to further send a message indicating an instruction regarding the operation of the moving body to the user. .. For example, when it is time to send a message, first send a message that calms the user's psychological state, such as "I was surprised! Calm down! Calm down". After that, instructions regarding the operation of the steering wheel and the operation of the accelerator and brake are given. For example, it sends a message such as "Please slow down slowly" or "Please keep a long distance between vehicles".

In this way, a message for switching the psychological state of the user may be sent first, and after the psychological state of the user is switched, an instruction regarding the operation may be sent. In this regard, even if the instruction regarding the operation is sent first without doing so, it is assumed that the excited user may not calmly listen to the instruction regarding the operation. However, with this device, a message for switching the psychological state of the user is first sent, and as a result, the psychological state of the user is first switched, for example, an instruction is sent after the user is in a calm psychological state. , The user can calmly listen to the operation instructions.

In addition, as another variation example, when it is detected that a situation corresponding to a violation of traffic rules has occurred due to the satisfaction of the detection condition, what kind of operation should be performed to prevent the violation? It is advisable to send a message to explain to the user. In this way, it is sufficient for the user to know what kind of operation was performed to prevent the violation of the traffic rules.

In this case, the "message explaining what kind of operation did not cause the violation" is, for example, a message such as "the accelerator was pressed too much" or "the brake should have been applied early". Good. As a result, when a traffic rule violation occurs, the user knows not only the fact that the traffic rule violation has occurred, but also how to operate the vehicle so that the violation does not occur. Therefore, the user may not cause the same operation error in the future operation.

In addition, a message may be sent explaining what kind of traffic rule the violating traffic rule is. By doing so, the user can know what kind of traffic rule the contrary traffic rule is. As a result, the user knows not only the fact that the traffic rule has been violated, but also what kind of rule the violated traffic rule is. In this respect, the traffic rules are diverse, and it is possible that the user does not completely grasp all the traffic rules, but the message from this device allows the user to grasp the traffic rules that were not fully grasped. It is good because it becomes.

Further, it is preferable to send each of the above-mentioned messages so that the user can detect the message even while the vehicle is being operated. In this way, the user can reliably perceive the message. During the operation of the moving body, for example, the driver visually refers to the front or the rear-view mirror, the steering wheel is grasped by the sense of touch to rotate the steering wheel, and the accelerator or brake is depressed. Therefore, it is conceivable to send a message so that the user can detect it by using abilities other than the abilities of the five senses of the user used for such an operation. For example, it is preferable to send a voice message so that it can be detected by the user's hearing, which is relatively unused for the operation. At the same time, it is also possible to display a message on the display device.

Further, as another modification, the message sending device 100 may be realized by a device having a function of a drive recorder or a device having a function of a radar detector.
