Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a traffic information display system using a portable telephone capable of making a telephone call by wireless communication, and more particularly to various information such as parking lot information, traffic information (congestion information), a visible radio, and a weather forecast. The present invention relates to a traffic information display system capable of displaying on a mobile phone.

[0002]

2. Description of the Related Art In Japan, the first step of the next generation transportation system, which is a worldwide trend in recent years, is to transmit information managed by the Japan Road Traffic Information Center to each driver in almost real time and to use it effectively. 2. Description of the Related Art A road traffic information communication system (VICS) is used to reduce economic loss and traffic accidents caused by chronic traffic congestion. The VICS provides various kinds of information such as parking lot information, traffic congestion information, visible radio and weather forecasts to automobile drivers using an optical beacon or radio beacon wireless communication system and FM multiplex broadcasting. is there.

The VICS information is usually displayed on a display panel of a car navigation system. That is, as shown in FIG.
S receiver 1 is added, and VI
The signal received by the CS receiver 1 is given as digital data to the navigation control unit 3 of the car navigation system CN, and the navigation control unit 3 processes the signal and outputs it to the display panel 4 (monitor). This allows the driver to obtain various VICS information during driving. The display panel 4 is fixedly arranged in a front panel near a driver's seat in an automobile (conventional example 1).

[0004]

When the VICS information is displayed on the display panel 4 of the car navigation system CN as in the prior art example 1, the VICS information is almost always accompanied by character information. In order to ensure recognition, it is necessary to watch the display panel 4 for a certain period of time.

[0005] However, when driving a car, even a slight deviation of the driver may hinder the driver's decision to drive, especially when the driver should concentrate his attention on driving at a corner or a bad road with poor visibility. Attention to the display panel 4 is very dangerous. Conversely, despite the fact that important VICS information is displayed on the display panel 4, the driver may concentrate on driving and may overlook the displayed VICS information.

[0006] In consideration of the above, the driver is required to pay VIC
If the S information is confirmed while the vehicle is stopped, the danger caused by watching the display panel 4 during driving can be easily avoided.

However, there are times when there is no time to check the VICS information while staying in the car slowly after stopping the car, such as after arriving at the destination in a hurry. The pursuit of was desired.

On the other hand, as disclosed in, for example, JP-A-8-33003 (conventional example 2) and JP-A-8-84172 (conventional example 3), a receiver for FM multiplex broadcasting (text broadcasting) is provided in a mobile phone. A technology for displaying FM multiplex broadcasts on a monitor screen of a mobile phone by incorporating the same has been disclosed. In these examples, the FM multiplex information can be slowly confirmed anytime and anywhere in the service area of the FM multiplex broadcast, not only in the car, but also at the place of departure or arrival such as at home or office. Therefore, even when there is no time to spare and the staying time in the automobile must be shortened, the information can be slowly visually recognized later, which is relatively convenient.

However, when FM multiplex broadcasting is received by a mobile phone as in the conventional examples 2 and 3, since the receiver is built in the mobile phone, the size and weight of the mobile phone are reduced, that is, a factor that hinders portability. become. Furthermore, if it is desired to obtain information not only in FM multiplex broadcasting but also in a wireless communication system using an optical beacon or a radio beacon, a receiver to be built into a mobile phone becomes considerably large, and the practicality of the mobile phone decreases.

Therefore, an object of the present invention is to provide a VICS using a mobile phone without impairing the portability of the mobile phone.
It is an object of the present invention to provide a traffic information display system capable of slowly recognizing traffic information such as information inside and outside a vehicle.

[0011]

Means for Solving the Problems In order to solve the above problems,
The present invention provides a receiver which is installed in an automobile and receives traffic information, a first display means which is installed in the automobile and displays traffic information received by the receiver, and which is embedded in the automobile and A first control unit configured to image-process traffic information received by the receiver and display-controlled on the first display unit; and a mobile phone detachably connected to the first control unit. The first control unit further has a function of transmitting information data related to the traffic information received by the receiver to the mobile phone connected to the first control unit, and the mobile phone includes the first mobile phone. A built-in memory for storing the information data transmitted from the control unit, an operation unit for giving a display instruction for the information data, a second display unit, and the information from the built-in memory based on a display instruction from the operation unit. Read the data and And it has a second control unit for displaying on the second display means. Thereby, traffic information can be displayed on the mobile phone without having a built-in receiver or the like on the mobile phone side, and convenience can be improved without impairing portability.

Preferably, the built-in memory is a writable read-only memory in which the information data remains even after the power of the mobile phone is turned off. As a result, the traffic information can be viewed at any time while the information data remains even after the power of the mobile phone is turned off.

[0013] More preferably, the apparatus further comprises a confirmation switch for instructing the first control unit to transmit the information data to the mobile phone, wherein the first control unit receives a transmission instruction by the confirmation switch. The information data is transmitted to the mobile phone only when given. Thereby, the transmission of the information data can be arbitrarily instructed only when the operator wants to see the traffic information on the mobile phone.

More preferably, the apparatus further comprises a detection circuit for detecting the presence or absence of the mobile phone at a predetermined position in the automobile, and the first control unit detects that the mobile phone is not present by the detection circuit. Sometimes, the first display means displays a predetermined message for prompting the user to install the mobile phone at a predetermined position and confirming whether to transmit the information data to the mobile phone. The information data is transmitted to the mobile phone when the presence of the mobile phone is confirmed and the transmission confirmation of the information data is obtained. By displaying the message in this manner, the operator can be prevented from forgetting to install the mobile phone, and the information data can be reliably transmitted to the mobile phone.

[0015] More preferably, the information data is image processing data expressed in pixel units. In a mobile phone that receives such image processing data expressed in pixel units, it is only necessary to display the data without performing any data processing work, so there is no need to provide the internal circuit with a data processing function. Mobile portability can be ensured.

Here, the information data is VICS information. In addition, as the first display means, a car navigation display panel that displays predetermined map information for performing virtual traveling in a car navigation system may be used, and further, as the first control unit,
The car navigation system may use a navigation control unit that recognizes the current position with respect to the map information and performs virtual traveling on a map according to actual traveling of the vehicle toward a traveling destination.

[0017] In this specification, the term "mobile phone" is not limited to a so-called "mobile phone" in a narrow sense, but includes a simple mobile phone (PHS).

When the push switch 53 does not come into contact with the mobile phone 40 (that is, when the mobile phone 40 does not exist on the receiving surface 51), the detection circuit 54 outputs a low signal as an “existence confirmation signal” to the navigation control. Telephone installation confirmation section 27 of section 22
Output to

The VICS receiver 10, the car navigation system 20, and the detection circuit 5 in the cradle 50
Reference numeral 4 denotes an accessory (ACC) switch when a normal four-stage switching ignition key cylinder is in the "accessory mode" or "on mode" among "off mode", "accessory mode", "on mode" and "start mode". It is activated when 60 is turned on.

The traffic information display system having the above configuration will be described with reference to the flowcharts of FIGS. It is assumed that the operation in the telephone installation confirmation unit 27 is performed in consideration of the “flag Fg” that indicates whether the driver or the like has an intention to write the VICS information to the mobile phone 40.

First, as in step S01 in FIG. 2, in the "off mode" of the ignition key cylinder, the flag Fg is initialized to "0" in advance. Then, as in step S02, when the driver or the like inserts the ignition key into the key cylinder and turns it to turn on the accessory switch 60, the VICS receiver 10, the car navigation system 20, and the cradle 50 are turned on. All electric devices such as are started.

Although the illustration of the car navigation operation is omitted in FIGS. 2 and 3, it is actually provided when the accessory switch 60 is turned on in step S02 or further provided separately. When the operation switch dedicated to the car navigation system 20 is turned on, the car navigation operation is performed. That is, when the car navigation system 20 is activated, the autonomous navigation control unit 25 in the navigation control unit 22 operates, and a vehicle speed pulse from a vehicle speed sensor (not shown) and a direction due to geomagnetism from a geomagnetic sensor (not shown). , The position of the vehicle on the map in the display panel 21 is controlled autonomously. At the same time, the GPS receiver 23 transmits the GP from the GPS satellite.
Start receiving the S signal through the antenna 23a, and
S control unit 24 receives GPS from GPS receiver 23
The position of the vehicle on the map is confirmed based on the signal information, and if there is a deviation from the position of the vehicle autonomously controlled by the autonomous navigation control unit 25, the position on the map is occasionally determined. Make corrections.

At the same time as the car navigation operation is performed, in step S03, the push switch 53
The detection circuit 54 detects whether the mobile phone 40 is installed on the receiving surface 51 of the cradle 50 (whether the mobile phone 40 is on or off) depending on the on / off state of the mobile phone 40. When the mobile phone 40 is not installed on the receiving surface 51, the detection circuit 54 outputs a low signal to the phone installation confirmation unit 27 of the navigation control unit 22 as an “existence confirmation signal”. In response to this, the telephone setting confirmation unit 27 gives an instruction to the image processing unit 28 to confirm writing of information to the mobile phone 40. As a result, in step S04, for example, as shown in FIG. 4, the display panel 21 prompts the user to install the mobile phone 40 and performs a confirmation display of information writing. The operator responds “Yes” to the message at this time by using the touch panel function of the display panel 21.
By selecting 61 or “No” 62 and instructing a point, it is determined in the subsequent operation whether or not there is writing to the mobile phone 40. That is, if "Yes" 61 is selected in step S04, the process proceeds to step S05, in which "1" is substituted for the flag Fg, and the fact that VICS information is not written to the mobile phone 40 is stored. On the other hand, if “No” 62 is selected in step S04, the installation of the mobile phone 40 on the receiving surface 51 of the cradle 50 is a prerequisite, and the processes in steps S03 and S04 are performed until the installation of the mobile phone 40 is performed. Is repeated.

If it is determined in step S03 that a mobile phone has been installed, or if "1" is substituted for the flag Fg in step S05, the flow advances to step S06 to manually select FM multiplex broadcasting or Automatic frequency setting (auto tuning) is performed as previously set. here,
As shown in FIG. 5, a frequency display column 63,
Automatic setting instruction column 64, manual frequency change icon 65a,
65b, and for storing the frequency displayed in the frequency display column 63 for automatic setting (AUTO) (SET)
Is displayed, and an operator gives a point instruction to each of the columns 63 to 66 with a finger or the like to select a channel. Alternatively, the above-described channel selection may be selectively performed by a method of selecting a menu screen as shown in FIG. 6 according to the content of information to be obtained.

After manual tuning or automatic frequency setting is performed in this way, in step S07, the VICS receiver 10 installed in the car receives FM multiplex broadcasting (VICS information) through the antenna 11, and The transmitted information is transmitted to the VICS information processing unit 26 of the car navigation system 20 (Step S08). The VICS information processing unit 26 performs a process according to a predetermined method such as IF detection or descrambling on the information provided from the VICS receiver 10, and edits an image in the image processing unit 28 accordingly. Then, an image is displayed on the display panel 21 like the parking lot information shown in FIG. 7 (step S0).
9). FIG. 7 shows the V of the map information level (level 3).
FIG. 7 is a diagram illustrating a state where ICS information is displayed.

At this point, the flag Fg is checked as in step S10 in FIG. That is, the flag F
If g is “1” (see step S05 in FIG. 2),
The driver or the like stores the VICS information in the internal memory 4 of the mobile phone 40.
Since the user does not have the intention to write to 1, the process ends.

On the other hand, in step S10, the flag Fg
Is "0", the flow advances to step S11 to wait for the confirmation switch 30 to be pressed and turned on.

If the driver or the like presses the confirmation switch 30 to indicate that the VICS information is to be transmitted to the mobile phone 40, in step S12, just in case, the detection circuit 5
4 detects whether the mobile phone 40 is installed in the cradle 50 (presence or absence). When the mobile phone 40 is not installed in the cradle 50, a low signal is output from the detection circuit 54 as a “presence / absence confirmation signal” to the telephone installation confirmation unit 27 of the navigation control unit 22. Gives an instruction to the image processing unit 28 to ensure that information is written to the mobile phone 40. As a result, in step S13, for example, an error message as shown in FIG.
The process of S12 is repeated. If the mobile phone 40 can be detected on the receiving surface 51 of the cradle 50 in step S12, the process proceeds to step S14.
, The image information in the bitmap format of the VICS information is written in the internal memory 41 of the mobile phone 40.

At this time, when the VICS information is stored in the built-in memory 41, the VICS information is immediately displayed on the monitor screen 42 as shown in FIG. Here, the built-in memory 41 of the mobile phone 40 is EEPR
Since a writable read-only memory (ROM) such as an OM is used, for example, the power switch of the mobile phone 40 is temporarily turned off, or the monitor screen 42 is displayed for normal use as the mobile phone 40. Even after switching, the VICS information in the built-in memory 41 can be called up and displayed on the monitor screen 42 at any time by operating the predetermined push button 44.

As described above, the information displayed on the display panel 21 of the car navigation system 20 installed in the car can also be displayed on the monitor screen 42 of the mobile phone 40. Even if there is not enough time to stay in the car after stopping and check the VICS information, there is no time to carry the mobile phone 40 at the time of getting off.
The VICS information can be slowly viewed on the monitor screen 42 of the mobile phone 40, and the convenience is improved as compared with the first conventional example.

Further, the VICS receiver 10 and the navigation control unit 22 (VICS information processing unit 26) installed in the automobile are used to display the VICS on the monitor screen 42 of the mobile phone 40.
Since the ICS information is displayed, the number of circuit components inside the mobile phone 40 can be significantly reduced as compared with the case where a receiver is built in the mobile phone as in the conventional examples 2 and 3, and The size and weight (portability) can be maintained. Also, in particular, optical beacons and radio beacons can not obtain information unless they pass through that place,
In this regard, while having portability, VI
The traffic information display system for receiving CS information can receive information on an optical beacon or a radio beacon more reliably than in a case where a receiver is simply built in a mobile phone as in conventional examples 2 and 3.

In the description along the flowcharts of FIGS. 2 and 3, the receiving operation of the FM multiplex broadcast is described as an example. However, the same operation is performed for the optical beacon signal and the radio wave beacon signal as the monitor screen of the portable telephone 40. Needless to say, VICS information can be displayed at 42.

Further, the information to be displayed is not limited to the VICS information. For example, ATIS information implemented by the Tokyo Metropolitan Government and the National Police Agency, or FM multiplex broadcasting only, optical beacon information only, or radio wave beacon only Needless to say, the present invention can be applied to any system related to the traffic information display system, such as the simple system described above.

The received traffic information is image-processed by the first control unit also incorporated in the car and is displayed on the second display means of the mobile phone. Later, the traffic information can be slowly viewed on the second display means of the mobile phone, and the convenience is improved as compared with the conventional example 1 in which the traffic information must be viewed in the car. Further, the traffic information can be displayed on the mobile phone without incorporating a receiver or the like in the mobile phone as in the conventional examples 2 and 3, and the convenience can be improved without impairing the portability.

According to the fourth aspect of the present invention, there is further provided a detection circuit for detecting the presence or absence of the mobile phone at a predetermined position in the automobile, and the first control unit detects that the mobile phone is not present in the detection circuit. When a message is detected, a predetermined message for confirming whether to transmit information data to the mobile phone is sent to the first message.
The operator can be prevented from forgetting to install the mobile phone, and the information data can be reliably transmitted to the mobile phone.

According to the fifth aspect of the invention, the image processing data expressed in pixel units is used as the information data transmitted from the first control unit to the mobile phone.
The mobile phone that receives the image processing data only needs to display the data without performing any data processing work. Therefore, it is not necessary to provide the internal circuit with a data processing function, and the portability of the mobile phone can be secured. .

According to the present invention, an existing car navigation display panel is used as the first display means and an existing navigation control section is used as the first control section. Thus, there is an effect that the traffic information reception processing element installed in the vehicle can be used as it is, and a large increase in the number of circuit components inside the vehicle can be avoided.
