Abstract

PURPOSE:To reduce the operation of a drive for a safe driving by limiting the operable range by a driver while a traveling body is driving as compared with a case when it is stopped. CONSTITUTION:Even if either of a driver and a passenger 3 operates a control means 4 while a traveling body is stopped, a response means 12 responds according to the operation input. On the other hand, while the traveling body is traveling, the identification signal from an operator identification signal generation means 5 is added to the passenger 3, it is so controlled that the identification signal component is detected by an operator identification signal component detection means 7 when the passenger 3 operates the control means 4 and then an operation range control means 10 transfers the output of the operation means 4 to the response means 12 so that the response means 12 responds exactly as the operation of the passenger 3 and does not respond to the operation of the driver.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention can be used, for example, in an operating section of a vehicle-mounted navigation device, and by identifying the operator while the vehicle is traveling, such as limiting the range in which the driver can operate. The present invention relates to a moving body control device capable of setting an operation range according to an operator.

[0002]

2. Description of the Related Art For example, in a vehicle equipped with an in-vehicle navigation device, it is dangerous for the driver to perform complicated operation of this device while the vehicle is running, but there is no particular problem for the passenger to operate it.

Therefore, when a passenger other than the driver operates the above-mentioned device while a moving body such as an automobile is moving, the operation command is accepted, and when the driver operates it, the operation command is not accepted. Safety is improved.

In order to meet such a demand, a vehicle-mounted navigation system as shown in FIG. 12 has been proposed (see, for example, Japanese Utility Model Laid-Open No. 4-78514).

FIG. 12 is a block diagram showing a schematic structure thereof. In the figure, 111 is a vehicle speed sensor for generating a pulse signal each time a vehicle (not shown) travels a predetermined distance, 112.
Is a geomagnetic sensor that detects the absolute traveling direction of the vehicle based on the geomagnetism, 113 is a gyro sensor that detects the relative traveling direction of the vehicle, and 114 is C that displays the current position of the vehicle.
RT, 115 is an operation unit for displaying various information on the CRT 114, 116 is a buzzer for issuing a warning when the operation state of the operation unit 115 is not appropriate, and notifying the end of various processes,
117 is an operation switch provided at a position where it cannot be easily operated from the driver's seat (not shown) in the vehicle, 118 is a passenger seating detection sensor for detecting that the passenger is seated in the passenger's seat (not shown) in the vehicle, 119 is a CD-RO storing map information and the like
M and 110 are connected to the constituent elements indicated by the reference numerals 111 to 119, perform data processing according to a predetermined program, and CR
This is a controller for controlling the display of T114 and the like.

Next, the main part of the operation of the controller 110 will be described. The controller 110 calculates the current position of the vehicle based on the speed detection signal from the vehicle speed sensor 111 and each direction signal from the geomagnetic sensor 112 and the gyro sensor 113, and displays it on the CRT 114 together with the map data read from the CD-ROM 119. To do. Further, when the operation unit 115 is operated, a plurality of types of guidance information and the like related to the vicinity of the current position of the vehicle are displayed on the CRT 114, and at the same time the instruction information is displayed. According to this instruction information, the desired guidance information is displayed on the operation unit
Select by 115. At this time, if the operation switch 117 is operated or the passenger seating detection sensor 118 determines that there is a passenger in the passenger seat while traveling, the operator of the operation unit 115 is a person other than the driver. It is judged that there is, and the selected guide information is displayed on the CRT 114. On the contrary, when it is determined that the operation switch 117 is not operated or that no passenger is seated in the passenger seat, the operation command from the operation unit 115 is not accepted.

[0007]

Since the conventional control device for a moving body is configured as described above, the passenger seating detection sensor 118 judges that the luggage is not seated even if the passenger is not seated in the passenger seat. When the above is placed on the seat, it is determined that there is a seated person in the passenger seat, so that there is a problem that the controller 110 accepts an input from the operation unit 115 by the driver.

I / O circuits 26a and 26b, CPU 26c,
It has a ROM 26d and a RAM 26e. Other parts are the same as in FIG.

Next, the operation of the embodiment constructed as described above will be described with reference to FIG.
It will be described based on. First, by turning on an ignition switch (not shown) of the automobile, the power of this device is turned on, and the microcomputer 26 is power-on reset to start the operation. Next, initialization (step S401)
Then, in steps S402 and S403, the CD-ROM player 13
The map data is input from, the data is processed, and then output to the display control circuit 23. The display control circuit 23 draws a map on the LCD 17 based on the input map data. FIG. 5 shows an example of the display, and 17a shows a road. A symbol 17b for touch switch input is also displayed. Next, in steps S404 to S407, the direction sensor 14 and the vehicle speed sensor 15
The traveling direction and the unit distance of the automobile are input respectively, and as is well known, the present position is calculated by integrating based on these inputs and output to the display control circuit 23. The display control circuit 23 receives this output and, as shown in FIG.
A mark 17c indicating the current position is drawn at D17. In addition, in FIG. 5, the locus 17d of the automobile traveled is also displayed.

Next, in step S408, it is determined whether or not the automobile is running. If a timer (not shown) built in the microcomputer 26 is used, the vehicle speed can be calculated from the unit distance signal input in step S405, so it can be determined whether or not the vehicle is traveling. If it is determined that the vehicle is running, step
S409 is selected and the operator identification signal generating means 5 is driven.
The operator identification signal generating means 5 generates an identification signal and supplies it to the operator identification signal applying means 6. As a result, the identification signal is applied to the passenger sitting on the passenger seat 2.

Next, in step S410, an operation signal indicating whether or not the driver or fellow passenger touches the symbol 17b shown in FIG. 5 with the finger is input from the touch switch control circuit 24. Next, in step S411, the signal from the transparent electrode 22 is amplified and input by the amplifier circuit 25, and in step S412, the identification signal applied from the operator identification signal applying means 6 to the passenger 3 is included in this input signal. It is determined whether or not the component is included, and if it is included, step S413 is selected, a predetermined operation is performed according to the operation signal input in step S410, and the process returns to step S404 again to repeat the same operation. . For example, if the symbol 17b is operated,
In response to this, the microcomputer 26 gives an output to the display control circuit 23 to display the touch switch input symbols 17e to 17h as shown in FIG. Symbol 17e is for scrolling the map vertically and horizontally, and symbol 17f is for changing to a small-scale wide area map, symbol
17g is for changing to a detailed map with a large scale, and symbol 17h is for displaying service information such as tourist information. When the passenger 3 is touching these symbols 17e to 17h with his / her finger, while the vehicle is traveling, steps S408 to S413 are executed in the same manner as described above, and a predetermined operation according to the operation signal is performed. If a person other than the passenger 3 touches the symbol 17b or the like while traveling, for example, the operator identification signal is not applied to the driver, and thus the identification signal component is not detected in step S412. Step S4
13 is not executed and the process returns to step S404.

If the vehicle is not traveling, step S414 is selected in step S408 to output a signal for stopping the operator identification signal generating means, and then step S415 is followed.
Similar to S410, an operation signal is input, step S413 is immediately executed, and the operation according to the operation signal is executed as described above.

Note that steps S408 and S412 correspond to the operation range control means 10 and operation range changing means 11 shown in FIG. 1, and step S413 also corresponds to the response means 12.

In this way, when the vehicle is running, the transparent electrode 22
Only when the operator identification signal component from is detected, that is, only when the passenger 3 operates, the operation according to the operation is executed, and when the operator identification signal component is not detected,
The operation input is ignored. When the vehicle is not traveling, the operation according to the operation input is executed regardless of whether or not the operator identification signal is present, that is, both the driver and the passenger.

Therefore, since the driver's operation input is not accepted during traveling, the driver does not operate during traveling and operates only while the vehicle is stopped, so that driving is safe.

Further, since the operating means 4 and the operator identification signal component detecting means 7 are integrally structured, the operator need only perform the conventional operation without performing any extra operation, which is very convenient. .

Example 2. FIG. 7 shows another embodiment, 27 is a steering wheel (hereinafter referred to as steering) which is one of driver's control devices, and 28 is an operator identification signal applying means having the same function as in the first embodiment. The operator identification signal from the operator identification signal generating means 5 is applied to the driver who holds the steering wheel 27, and 29 is a dashboard. FIG. 8 shows a front view of the steering 27,
FIG. 9 is a sectional view taken along line IX-IX in FIG. 8, in which the operator identification signal applying means 28 made of a tubular conductor is embedded inside the steering wheel 27. Other configurations are the same as those of the first embodiment except that the operation of the microcomputer 26 is partially different.

In the second embodiment, a steering wheel 27 is used instead of the passenger seat 2 of the first embodiment, and a steering wheel 28 is used instead of the operator identification signal applying means 6 in the same manner as in the first embodiment. Instead of detecting the operation, in the present embodiment, the operation of the driver is detected so that the operation by the driver cannot be performed during traveling.

The operation will be described with reference to FIG. 10 showing the flowchart of the microcomputer 26. The operation of each step of steps S401 to S411 and S413 to S415 is the same as that of FIG. 4, and only the operation of step S1001 is different. That is, in step S1001, if it is determined that there is the operator identification signal component input in step S411, it is determined that the driver holding the steering wheel 27 has operated, and even if the operation signal is input in step S410. , And returns to step S404 without responding to this. On the other hand, if it is determined in step S1001 that there is no operator identification signal component, it is determined that a passenger other than the driver has operated, and the operation signal input in step S410 is responded to in step S413.

Therefore, the driver operates the steering wheel 27 while traveling.
As long as the driver is holding, the driver's operation input is not accepted, the driver does not operate while traveling, and operates only while the vehicle is stopped, so driving is safe.

Example 3. FIG. 11 shows still another embodiment, and shows a part of the interior of the automobile. In this example, instead of the operator identification signal applying means 6 of FIG. 1 showing the first embodiment, an operator identification signal applying means 30 is provided on the passenger seat side of the dashboard 29, and other configurations are implemented. Same as Example 1. Regarding the operation, the passenger 31 in the passenger seat touches the operator identification signal applying means 30 with one hand while touching the touch switch symbols 17b, 17e to 17h displayed on the display unit 16 with the other hand 31b. Thus, it is determined that the passenger has operated the vehicle even while the vehicle is running, and the predetermined operation is executed based on the operation signal.

Therefore, also in this embodiment, the first embodiment
The same effect as can be obtained.

Example 4. In the second embodiment, the operator identification signal applying means 28 is provided on the steering wheel 27, but the same effect can be obtained by providing it on the driver's seat (not shown).

Example 5. In the first to fourth embodiments, when the driver operates the operation means 4 during traveling, it is decided that the operation is not responded to at all, but some operations that do not hinder safe driving, for example, by symbols 17f and 17g. You may make it respond to an operation.

Example 6. In the first to fifth embodiments, the operating means 4 and the operator identification signal component detecting means 7 are integrally formed, but it goes without saying that they may be provided separately if there is no problem in operation.

Example 7. Although the example applied to the navigation device has been described in the first to sixth embodiments, the present invention is not limited to this and can be applied to various devices that need to operate complicated functions such as a preset memory operation of a car radio and a setting operation of the same graphic equalizer. Needless to say, it can be applied.

Example 8. In the first embodiment, while the microcomputer is operating, it is determined in step S408 whether or not the vehicle is running, and the operator identification signal generating means 5 is driven / stopped. There is no problem if the entire device is kept in a driving state during operation.
