DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to the development of mobile communication technology, and in a social situation where many users use mobile communication anywhere, even in a running vehicle, safety and security can be improved. The present invention relates to an in-vehicle information distribution system capable of receiving necessary information while securing the information.

[0002]

2. Description of the Related Art In order to perform communication between a vehicle and the outside,
Conventionally, as shown in FIG. 6, a wireless technology such as a car phone or a mobile phone 91 is directly brought into a vehicle to realize communication. By preparing an adapter for the mobile phone 91 in the vehicle and connecting the hands-free microphone 92 and the speaker 93 to the adapter for driving safety, the driver does not need to hold the mobile phone 91 in the vehicle. Some devices have been devised to enable calls.

[0003] In addition, by setting an answering machine service in advance by operating a special number before driving a car, a guidance is given to a caller at the time of an incoming call that he cannot answer the call because he is "driving". Technology is also being considered.

[0004]

As described above, the prior art has focused on enabling a user to use a mobile phone in a vehicle. For this reason, communication is received from outside regardless of the situation inside the vehicle, for example, when the driver is changing lanes at high speed, when there is a curve or oncoming vehicle, or when there is a falling object on the road. In such a case, there is also a problem that communication may come in from outside, distracting the driver of the nervous driver and increasing the risk of an accident.

Further, in the case of the conventional answering machine service, since guidance is provided to the caller regardless of whether or not the user is actually driving, an important message which must be contacted urgently cannot be transmitted. However, there is a problem that the great feature of portableness of a mobile phone cannot be utilized.

Further, when a conversation is carried out using the speaker 93 in a hands-free manner, the contents of the conversation can be heard by all the occupants, and thus there is a problem in terms of privacy protection and confidentiality.

[0007] The present invention is to solve the above problems, in the vehicle, to provide information distribution system considering the status of the driver and other passengers, and purpose and Turkey improved safety I do.

[0008]

FIG. 1 shows an example of a block configuration for explaining the outline of the present invention. According to the first aspect of the present invention, for example, a communication unit 1 for performing communication with an external system and input / output devices corresponding to an appropriate medium such as a mobile phone, a screen, and a speaker transmit received information to a vehicle. A reception information notification unit 2 to be presented to the passenger, and a traveling state monitoring unit 3 having a function of monitoring the traveling speed of the vehicle
And a vehicle environment recognizing unit 4 having a function of recognizing an environment around the vehicle, a received information storing / converting unit 5 having a server function of storing / converting received information, and information according to the situation of the vehicle and the passenger. The main feature is that it has a control unit 6 that performs distribution control. The control unit 6 includes the running state monitoring unit 3
Or the state is detected by the state monitoring means by the vehicle environment recognition unit 4.
Information can be distributed according to the condition of the vehicle
Status and determine whether the current status is
Set to one of the states that information distribution is not possible. And information
If the distribution is possible, the
Information is delivered in real time, and
If necessary, extract information from the received information as to whether it is important
The urgency of the received information
Select the media format to output the received information
Media conversion and distributes the received information. On the other hand, urgent
If it is not necessary, wait until the information
Controls information distribution.

[0010] In particular, in the invention described in claim 2, the control unit 6 performs control to notify the information sender of the external system of the result of the information distribution control.

Further, according to the third aspect of the present invention, when the traveling state monitoring unit 3 detects that the vehicle is traveling at a certain speed or higher, the function of stopping the transmission from the driver is provided. The main feature is that it has a running call stopping unit 8 that is provided.

[0011]

The present invention is different from the prior art in that, when providing received information to a passenger, in consideration of the situation of the passenger and the vehicle, the notification is not given in real time in some cases. However, the difference is that notification is made using media (such as voice and screen information) suitable for the situation.

The present invention operates as follows. [Inventions of Claims 1 and 2] Generally, the running condition of an automobile can be determined by monitoring its speed and the situation around the vehicle. The running state monitoring unit 3
The traveling speed is measured from the data of the driving actuator of the vehicle. The vehicle environment recognizing unit 4 measures a road width, a distance to an adjacent vehicle, and the like using a non-contact type vehicle-mounted sensor such as a laser radar or a radio wave radar as a situation around the vehicle.

When the communication unit 1 receives a telephone call or mail from the outside, the reception information storage / conversion unit 5, which is a server placed in the vehicle, temporarily stores all information. The control unit 6 controls the vehicle at a constant speed when the traveling speed of the vehicle is equal to or less than the constant speed and the driver has enough time to concentrate on things other than driving, such as waiting for a traffic light or a long straight road. When the vehicle is traveling, the reception information notifying unit 2 notifies the reception information stored in the reception information storage / conversion unit 5.

When the driver is unable to respond immediately, the control unit 6 "transmits a message to the information sender, although the vehicle is running and it is difficult to make a real-time call," A reply to the effect is automatically transmitted on behalf of the driver.

[0016] Depending on the content of the received message, information that really needs urgency may be included. In this case, the reception information storage / conversion unit 5 can also select a medium that does not load the driver and notify the driver of the arrival of the message with high urgency. It is also possible to analyze the content of the received message by a method such as semantic analysis or language element analysis, and notify the driver only of the purpose of the message.

According to the third aspect of the present invention, even when the driver is talking while the vehicle is running, the result of monitoring by the running state monitor 3 indicates that the vehicle is running at a certain speed or higher. If it is detected that there is
Stops the transmission from the driver and temporarily suspends or terminates the call. At this time, a message to the effect that the communication is terminated (or interrupted) because the vehicle is running and real-time communication is difficult is automatically transmitted to the communication partner. If it is detected that the vehicle is traveling at a certain speed or higher, calling from the driver is prohibited.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below. Figure 2 [form state of the present invention] is a diagram showing an embodiment of the present invention.

The vehicle 100 is driven by an engine unit including a speed control processor 30, a servo mechanism 31, and an actuator 32 for controlling fuel according to the speed condition. At this time, the running speed is monitored from the actuator 32, and the speed information collecting unit 33 collects the speed information. For example, when the vehicle speed is extremely high and the driver's condition is expected to be nervous, the speed information collecting unit 33
Informs the server control unit 60 that it is dangerous to distribute information.

On the other hand, an on-board sensor 40 for monitoring the surroundings of the vehicle 100 constantly monitors the external situation of the vehicle 100. If a falling object or a sudden jump is detected, the speed control processor 30 informs the speed control processor 30 of an emergency brake or the like. Give instructions. In this case, the control information output by the speed control processor 30 is also collected in the speed information collecting unit 33, and is notified to the server control unit 60 as the expected speed together with the current vehicle speed.

The in-vehicle sensor 40 constantly informs the vehicle environment determining unit 41 of information about the distance to an adjacent vehicle, the number of vehicles, the width of the traveling lane, and the like. The vehicle environment determination unit 41 determines whether the vehicle is traveling in a traffic jam or a narrow place based on the obtained information, and sends the result to the server control unit 60.

Based on the above information, the server control section 60 determines whether or not communication from the outside to the occupants of the vehicle 100, particularly to the driver, is safe. Regarding the communication system in the vehicle 100, information from the outside is first received by the communication device 10 and then temporarily stored in the multimedia server unit 50.

At that time, the server control unit 60 determines that the vehicle 100 is in a relatively safe state, for example, in a signal waiting state or in an auto cruise state on a highway.
, Immediately notifies the multimedia server unit 50 of the received information, and
1 is instructed to convert the media into a media suitable for the user (driver or the like) and to notify the user of the media, and control so that communication with the outside is possible in real time.

On the other hand, if the server control unit 60 determines that it is not secure, the multimedia server unit 50 returns to the information transmitting side an e-mail stating "although the call is currently in progress but the message cannot be transmitted". For a person who wants to convey a message in the car, only the fact that the message is coming is conveyed through the screen 20, the speaker 21 or the like.

If the message has urgent contents, the server control unit 60 determines the urgency based on the rules defined between the sender and the receiver, and the multimedia server unit 50 displays the telop on the screen 20. It is also possible to send a message content or to notify only a contact.

FIG. 3 is a processing flowchart for determining whether or not information distribution is possible by recognizing the running state of the vehicle and the vehicle environment in the above embodiment.
The server control unit 60 monitors the driving speed collected by the speed information collecting unit 33 from the actuator 32 (S1), and monitors the vehicle environment determined by the vehicle environment determining unit 41 (S2). The server control unit 60 calculates the load on the driver from the information (S3) and determines whether or not the information can be delivered (S4). If information distribution is possible, the current state is set to "information distribution possible" (S5),
If information distribution is not possible, the current state is set to "information distribution impossible" (S6).

FIG. 4 is a processing flowchart relating to distribution of the received information. When an external message is received by the vehicle-mounted communication device 10 (S11), the received message is stored in the multimedia server unit 50 (S11).
12). The server control unit 60 determines whether the current state is “information delivery possible” or “information delivery impossible” (S
13). In the case of "information distribution possible", the driver directly notifies the information held by the multimedia server unit 50 in real time (S14).

If the current state is "information delivery impossible", information indicating whether the message is important is extracted from the received message (S15), and it is determined whether the received message requires urgency. (S16).

If the received message is urgent, a media format for outputting the received information is selected (S17), and media conversion such as converting character data into voice data is performed (S18). , Driver 20
The received information is distributed to 0 (S19).

If the received message is not urgent, the received message is stored again in the multimedia server unit 50 (S20), and the information sender is asked, for example, , A message is always transmitted "(S21). Then, it waits for "information distribution possible" (S22). If it becomes "information distribution possible", it is determined whether or not the information can be redistributed (S23). If the information can be redistributed, the process from S17 is performed. Judgment of whether or not information can be redistributed is based on the existence of externally received information, because if a new message happens to be received from the outside, the distribution of the received information may collide. After re-distribution.

Further, when the driver is talking while traveling assuming that the driver is in a relatively stable traveling state, the server control unit 60 determines that the traveling speed is equal to or higher than a certain speed based on the monitoring result of the speed information collecting unit 33. When it is determined that the call is dangerous, the transmission of the driver is stopped, and a message is automatically sent from the multimedia server unit 50 to the other party to the effect that the call is stopped due to the dangerous driving condition. I do.

[ Embodiment of Related Invention ] An embodiment of the invention related to the present invention will be described.
In this embodiment, information on the inside of the vehicle 100, that is, information on the number of passengers and their own recognition, or information on a person who can read mail is also used as information for controlling the distribution of the received information. I do.

First, the personal authentication setting section 70 performs personal authentication of all the occupants of the vehicle at the time of boarding by inputting from an ID card or other input means, and registers the ID information of each individual.

The distribution level control unit 71 determines the distribution destination of the received message based on the information registered in the personal authentication setting unit 70, and notifies the server control unit 60 of the distribution level. The server control unit 60 controls the multimedia server unit 50 based on the received distribution level.

Depending on the distribution level, for example, "notify only to the driver", "notify only to specific passengers", and "notify to all passengers" determine who can be received in the vehicle.
Alternatively, the received information is displayed on the screen 20 according to the distribution level.
May be determined, output from the speaker 21, or output to the mobile phone 90 or other mobile terminal.

For example, when a certain sender sends a message to the passenger A of the vehicle 100 and the content is not to be transmitted to the passengers other than the passenger A, only a person having a specific name or ID is required. (Here, the passenger A) is transmitted to the vehicle with a message with a comment notifying it.

In the vehicle 100, when a communication message is input from the outside to the occupant A, the distribution level is specified by comparing the personal authentication information of the occupant registered in advance with the comment in the received message. Notify only the passenger (A) of the vehicle. " In accordance with this distribution level, the multimedia server unit 50 notifies only the passenger A of the fact that the message has been received via the screen 20 or the like, regardless of the traveling state of the vehicle 100. Passenger A who has received the message on screen 20 obtains the information of the message without being known to other passengers, for example, by directly connecting his or her portable terminal to multimedia server unit 50. It becomes possible.

If the received message does not include a comment for identifying the recipient, the distribution level is set to “notify all passengers”, and the screen 20 and the speaker 21 are set via the multimedia server unit 50. Vehicle 100
Notify all passengers.

In addition, other services such as setting the distribution level to “notify only the driver” in a specific case are conceivable, but taking into account the safety of the vehicle environment,
In the sense of providing information stored on the server,
Considered as the same kind of service.

FIG. 5 is a processing flowchart of the embodiment of the related invention . When the passenger gets into the vehicle,
An input device such as an ID card or a touch panel
Information such as the D number and whether or not the driver is registered in the distribution level control table (S31).

When an external message is received (S3)
2), the received message is sent to the multimedia server unit 5
0 is stored (S33). It is determined whether or not the received message has a comment specifying the recipient (S3).
4) If there is a comment, authentication information is extracted from the comment and a distribution level is set (S35). If there is no comment, the distribution level is set to "general (notify all passengers)" (S36).

The received message is converted into an appropriate media format according to the distribution level (S37), and the received information is output based on the distribution level (S38). For example, if the information is for a specific passenger, the notified passenger will:
Connect its own cellular phone in the multimedia server 50, a call with an external caller via the in-vehicle communications device 10.

[0044] Incidentally, a combination of embodiments of the described embodiment form state Contact <br/> spare related aspect of the present invention above, it is also possible to implement the present invention.

[0045]

As described above, according to the present invention,
Since the communication control is performed according to the vehicle condition, the safety is improved, and the information security level of the user can be improved by using the same mechanism.

Further, when the driver has a conversation while traveling, safety can be improved by stopping the transmission from the driver side at a certain speed or higher.
