Abstract

<P>PROBLEM TO BE SOLVED: To provide an instrument usage restriction system and an instrument usage restriction determination system for performing the suitable usage restriction of an instrument in a movement body such as a vehicle of an automobile. <P>SOLUTION: When a position of an engine key is determined (S101) and positioned at a position of "Acc" or more, the operation state of a side brake operated by an operation part of a fixed instrument is read by an operation part of a conveyable instrument through a communication part (S102). The operation part of the conveyable instrument determines that the side brake is turned on or off (S103). When the side brake is turned off, the operation part of the conveyable instrument reads signal intensity from a receiving part of the conveyable instrument (S104). It is determined from the signal intensity whether or not the conveyable instrument is positioned within a usage restriction range formed making a signal generator as a center (S105). When the conveyable instrument is positioned within a usage restriction range, the usage of the conveyable instrument is forbidden (S106). <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention relates to a device use restriction system and a display restriction system for restricting device use according to the situation in a vehicle, for example.

  For example, when a driver watches a screen of a mobile phone in a car and sends an e-mail, etc., the driver's reaction speed may be lower than usual, leading to a traffic accident. It is forbidden except when it is stopped.

  Here, recently, a reproduction device such as a car navigation device or a DVD player is installed or brought into an automobile. It is not preferable in terms of traffic safety that the driver operates the car navigation device or the playback device or views the display screen while driving, as in the case of the mobile phone.

  In order to prevent such a situation, various methods and systems have been conventionally proposed. For example, Patent Document 1 discloses a system for regulating wireless communication performed between a base station and a mobile station (mobile phone) as necessary. Specifically, a regulation device capable of regulating functions for mobile stations in a regulation area (for example, a library, a concert hall, a hospital, etc.) has been proposed. The restriction device is prepared in advance with a plurality of restriction contents, and the administrator of the restriction device can select the contents of the function restriction (for example, power-off of the mobile station) from among them.

JP 2001-69546 A (pages 7-8, FIG. 1)

However, in the system of Patent Document 1, functional regulation is uniformly performed in the regulation area. In this respect, it is inconvenient to use the system of Patent Document 1 for regulation in an automobile. That is, in an automobile, it is not preferable for traffic safety that a driver operates or views a display screen of a car navigation device or various playback devices while traveling, and should be regulated. On the other hand, there is no problem even if the driver sees the operation and display screen while the vehicle is stopped.
In addition, it is not preferable for passengers other than the driver to operate the car navigation device or various playback devices or view the display screen even when the vehicle is traveling, because there is no problem in terms of traffic safety.
Therefore, uniform function restriction within the restricted area may be an unnecessary restriction for the driver and the passenger. Such a problem is peculiar to not only automobiles but also moving bodies that carry passengers.

  The present invention has been made to solve the technical problems as described above, and an object of the present invention is to appropriately restrict the use of equipment in a moving body such as an automobile vehicle.

For this purpose, the present invention is applied to an equipment usage regulation system that regulates the use of portable equipment used by passengers in a passenger space of a moving body that moves with passengers. In this device usage system, the detection means detects that the device is located within a predetermined use restriction range that is a part of the passenger space of the moving body, and the use restriction means uses the device from the detection result by the detection means. To regulate.
In this detection means, a transmission source that emits a predetermined signal is installed in an occupant space of the moving body, and a receiving unit that receives the predetermined signal from the transmission source is attached to the device. And the acquisition means acquires information related to the position of the device in the passenger space of the moving body based on the signal received by the receiving unit, the determination means based on the information related to the position of the device acquired by the acquisition means, It is determined whether or not the device is located within a predetermined use regulation range that is a part of the passenger space of the moving body.
In such a configuration of the detection means, the transmission source is installed within a predetermined use regulation range, and the predetermined signal emitted from the transmission source is a radio signal having a constant intensity. The acquisition unit measures the signal strength as information regarding the position of the device for the signal received by the receiving unit. The determination means determines that the device is located within a predetermined use restriction range when the signal intensity measured by the acquisition means reaches a predetermined intensity.
Further, as another configuration of the detection means, the transmission source is installed outside a predetermined use regulation range, and the acquisition means relates to the position of the device whether or not the reception unit has received a signal emitted from the transmission source. It is acquired as information, and the determination unit determines that the device is located within a predetermined use restriction range when it is acquired by the acquisition unit that the reception unit has not received.

  From another point of view, in the device usage regulation system to which the present invention is applied, the acquisition unit acquires information on the stop state of the moving body. The detection means detects information related to the position of the device in the passenger space of the moving body. The determination unit determines whether or not the device is located within a predetermined use restriction range that is a part of the passenger space of the moving body, based on information on the position of the device detected by the detection unit. Then, the use restricting means restricts the use of the device based on the information regarding the stop state of the moving body acquired by the acquiring means and the determination result by the determining means. Specifically, the use restriction unit restricts the use of the device when the moving body is not in a stopped state and the device is located within a predetermined use restriction range.

Further, from another point of view of the present invention, in the display regulation system to which the present invention is applied, a portable device that can be carried in a vehicle that carries an occupant has a display unit and is used by the occupant. The fixed device fixed to the vehicle transmits visible information to be displayed on the display unit of the portable device to the portable device. An acquisition means acquires the information regarding the stop state of a vehicle from a vehicle. The determining means determines whether the portable device is located within a display restriction range set in advance in the vehicle, and the display restricting means is information relating to the vehicle stop state acquired by the acquiring means and the determining means. The display on the display unit of the portable device is regulated based on the determination result by. That is, the display restricting means restricts the display on the display unit of the portable device when the vehicle is not in a stopped state and the portable device is located within the display restriction range.
The information on the vehicle stop state acquired by the acquisition unit may be vehicle side brake operation information. The information on the vehicle stop state acquired by the acquisition unit includes the vehicle side brake operation information and vehicle speed. It may be information.

  ADVANTAGE OF THE INVENTION According to this invention, it becomes possible to perform appropriate use regulation of an apparatus in moving bodies, such as a motor vehicle.

Embodiments of the present invention will be described below in detail with reference to the accompanying drawings.
FIG. 1 is a schematic plan view showing an example of the case where the device usage regulation system according to the present embodiment is arranged in a vehicle 41.
As shown in FIG. 1, the device usage restriction system includes a portable device 10, a fixed device 20, and a signal generator 30. The device use restriction system is for restricting the use (operation / viewing) of the portable device 10 located in the inside 42 of the vehicle 41. More specifically, the device use restriction system indicates whether there is no problem in terms of traffic safety. It is for judging and permitting or prohibiting the use of the portable device 10.

The fixed device 20 is mounted in an instrument panel 43 (instrument panel). The fixed device 20 is configured so that information can be transferred to, for example, a 2.4 GHz wireless LAN (Local Area Network) with respect to the portable device 10 movable in the vehicle 42. That is, each of the portable device 10 and the fixed device 20 is provided with a communication unit to be described later, and various kinds of information can be transmitted to and received from the portable device 10 via each communication unit.
In addition, a parking signal for lighting a parking lamp (not shown) of the instrument panel 43 is supplied from the vehicle 41 to the fixed device 20. That is, the fixed device 20 detects a parking signal of 12V when a side brake (not shown) is applied, and detects 0V when the side brake is not applied.
Further, the fixed device 20 is connected to a ground (not shown), and accessory power is supplied from the vehicle 41. Instead of the accessory power supply, it may be configured to always supply the power supply + B. The accessory power supply is supplied only when the engine key is in a position of “Acc” or higher, and the constant power supply + B is always supplied with 12V regardless of the position of the engine key of the vehicle. It is.

As shown in FIG. 1, the signal generator 30 always generates an omnidirectional radio signal with a constant intensity. The signal generator 30 is provided in the driver seat 44. Specifically, the seat 44a of the driver's seat 44 is embedded at a position in front of the vehicle. The radio signal transmitted from the signal generator 30 is used to control the availability of the portable device 10 that receives the radio signal.
Accessory power is supplied from the vehicle 41 to the signal generator 30. That is, it is configured to continuously transmit a radio signal when accessory power is supplied from the vehicle.
Here, the radio signal transmitted from the signal generator 30 uses a signal having a frequency different from the frequency of the wireless LAN (for example, 2.4 GHz) used for communication between the portable device 10 and the fixed device 20. Thereby, it is possible to prevent the wireless signal transmitted from the signal generator 30 from adversely affecting the wireless LAN, such as interference. As the frequency of the radio signal generated by the signal generator 30, a frequency employed in an immobilizer, for example, 100 to 200 MHz is used. The immobilizer refers to an anti-theft device that cannot start the engine unless the ID code of a transponder (transmitter) embedded in an engine key (not shown) matches the ID code of the vehicle body (ECU: Electronic Control Units). .

As described above, the portable device 10 can be connected to the fixed device 20 by a wireless LAN, and is operated by a built-in power source (not shown). For this reason, any of the passengers seated in the driver's seat 44, the passenger seat 45, the rear seat 46, or the like can use the portable device 10 at that position.
Examples of the portable device 10 here include a navigation device that is not fixedly installed on the vehicle 41. In this case, the fixed device 20 has a function as a cradle (station) on which the navigation device can be detachably installed.
In addition, examples of the portable device 10 include a display device having a function of displaying AV contents of DVD media reproduced by the fixed device 20 and a TV program received by the fixed device 20. In this case, the fixed device 20 has a DVD playback unit and a tuner unit (not shown). The portable device 10 may also include a display device that displays various Internet homepages connected via the fixed device 20.
As described above, the portable device 10 is configured to display content as visible information such as image information sent from the fixed device 20 to passengers in the vehicle regardless of the seating position. Yes. As will be described later, the portable device 10 is prohibited from being used when it is located within a use restriction area (a range where the use of the portable device 10 is prohibited) A in the vehicle 42.

FIG. 2 is a schematic configuration diagram illustrating each configuration of the portable device 10, the fixed device 20, and the signal generator 30.
As shown in FIG. 2, the fixed device 20 includes a voltage detection unit 21, a calculation unit 22, and a communication unit 23. The voltage detector 21 detects the voltage of the input parking signal and outputs the detection result to the calculator 22. The calculation unit 22 calculates the operation state of the side brake from the detection result, and outputs the calculation result to the communication unit 23. The communication unit 23 transmits the calculation result to the portable device 10.
The fixed device 20 includes a storage unit 24, a display unit 25, and an operation unit 26. The storage unit 24 is for temporarily storing video information that is played back by the DVD playback unit and transmitted to the portable device 10 via the communication unit 23, for example. The display unit 25 is a part where necessary display is performed, and the operation unit 26 is a part for giving an operation instruction to the fixed device 20.

As shown in FIG. 2, the portable device 10 includes a receiving unit 11 and a calculation unit 12. The receiving unit 11 receives a radio signal transmitted from the signal generator 30 and measures its signal strength. The calculation unit 12 reads the measured signal strength from the reception unit 11 and determines the positional relationship with respect to the signal generator 30 based on the signal strength. That is, the calculation unit 12 determines whether or not the signal strength 30 has reached a predetermined threshold, and determines whether or not the portable device 10 is located within the use restriction range A based on the determination result.
Here, the signal strength of the non-directional radio signal transmitted from the signal generator 30 depends on the separation distance between the signal generator 30 and the portable device 10. Therefore, it is possible to estimate whether the portable device 10 is located within the use restriction range A or outside the use restriction range A by measuring the signal intensity and comparing the signal intensity with a predetermined threshold. it can.
The portable device 10 also includes a communication unit 13, a display unit 15, and an operation unit 16. The communication unit 13 of the portable device 10 is for performing communication with the fixed device 20. That is, as described above, the communication unit 13 of the portable device 10 receives the operation state of the side brake from the communication unit 23 of the fixed device 20 and should be displayed on the display unit 15 of the portable device 10. Receive. Various types of information are transmitted from the portable device 10 to the communication unit 23 of the fixed device 20. Various types of information received from the fixed device 20 by the communication unit 13 of the portable device 10 are output to the calculation unit 12.
As described above, the signal intensity measured by the receiving unit 11 of the portable device 10 is input to the calculation unit 12 of the portable device 10, and the operating state of the side brake detected by the voltage detection unit 21 of the fixed device 20. Is entered. Then, the computing unit 12 of the portable device 10 determines the position of the portable device 10 in the vehicle 42 based on the intensity signal, and determines the stop state of the vehicle 41 based on the operating state of the side brake. These two determination results Thus, as shown in the following table, control is performed as to whether the use of the portable device 10 should be permitted or prohibited.

That is, when the side brake is ON (the parking lamp is lit), the vehicle 41 is not traveling. Therefore, it is not necessary to prohibit the use of the portable device 10, and the use of the portable device 10 is allowed regardless of the reception intensity measured by the receiving unit 11 of the portable device 10.
On the other hand, when the side brake is OFF (the parking lamp is turned off), the driver is willing to travel even if the vehicle is traveling or not traveling. Therefore, the use of the portable device 10 by the driver should be prohibited for traffic safety, and the availability of the portable device 10 is controlled according to the reception intensity measured by the receiving unit 11 of the portable device 10. . Specifically, when the reception intensity reaches a predetermined threshold, it is determined that the portable device 10 is being used by the driver, and the use of the portable device 10 is prohibited. When the reception intensity does not reach the predetermined threshold value, it is determined that the portable device 10 is being used by an occupant other than the driver, and the use of the portable device 10 is permitted.

  Here, “use of the portable device 10 is prohibited” means that the operation from the operation unit 16 of the portable device 10 is invalidated, a warning screen is displayed on the display unit 15 of the portable device 10, and video It means to stop the renewal etc. When the use of the portable device 10 is prohibited, a signal indicating that the use of the portable device 10 is prohibited is transmitted from the communication unit 13 to the fixed device 20. The fixed device 20 that has received the signal via the communication unit 23 stops the data transfer if the data being transmitted to the portable device 10 exists in the storage unit 24. Further, the fixed device 20 displays on the display unit 25 of the fixed device 20 that the use of the portable device 10 is prohibited.

Thus, in the embodiment of the present invention, the driver cannot use the portable device 10 when the vehicle 41 is traveling. In addition, in other cases, that is, the use of the portable device 10 of an occupant other than the driver at the time of traveling and the use of the portable device 10 of all occupants including the driver at the time of stopping are permitted.
In other words, passengers other than the driver can use the portable device 10 regardless of whether the vehicle is stopped or traveling. For this reason, appropriate use regulation of the portable device 10 can be realized by determining whether the person using the portable device 10 in the vehicle 42 is a driver or a passenger. Further, by determining whether the vehicle is stopped or traveling, it is possible to allow the driver to use the vehicle at the time of stopping, so that it is possible to realize further appropriate use restrictions of the portable device 10.

The determination as to whether the use of the portable device 10 should be permitted or prohibited is made by the calculation unit 12 of the portable device 10, but the calculation unit 22 of the fixed device 20 determines the determination. Based on the result, it is also conceivable that the calculation unit 12 of the portable device 10 performs an invalidation process of the operation from the operation unit 16 and a warning display on the display unit 15.
Moreover, although the wireless LAN is used for the exchange between the portable device 10 and the fixed device 20, a wired system may be considered.

Next, the flow of processing in the device usage regulation system will be described with reference to FIG.
FIG. 3 is a flowchart of processing performed by the device usage regulation system.
First, an ECU (Electronic Control Unit) (not shown) determines whether or not the engine key is at a position equal to or higher than “Acc” (S101). When it is determined that the engine key is at a position higher than “Acc”, the operating state of the side brake (parking brake) calculated by the calculation unit 22 of the fixed device 20 is portable via the communication units 23 and 13. The calculation unit 12 of the device 10 reads (S102). The computing unit 12 of the portable device 10 determines whether the side brake is ON or OFF (S103). When the side brake is OFF, the calculation unit 12 of the portable device 10 reads the signal strength (radio wave strength) from the reception unit 11 of the portable device 10 (S104). Based on the signal intensity, the computing unit 12 of the portable device 10 determines whether or not the portable device 10 is located within the use restriction range A formed around the signal generator 30 (S105). When it is determined that the portable device 10 is located within the use restriction range A, the calculation unit 12 of the portable device 10 prohibits the use of the portable device 10 (S106).

When the portable device 10 is not located within the use regulation range A, the use of the portable device 10 is not prohibited (S107). Moreover, use of the portable apparatus 10 is not prohibited when the side brake is ON (S107).
Such use permission control is repeated at a frequency of, for example, once per second when the engine key is at a position equal to or higher than “Acc”. If the engine key is not at the position “Acc” or higher, the process ends.
When the portable device has a power switch (not shown), the above processing is performed only when the power switch is ON.

As described above, in the present embodiment, the use of the portable device 10 is allowed unconditionally when the side brake is ON. On the other hand, when the side brake is OFF, whether or not the portable device 10 can be used is controlled according to the position of the portable device 10 in the vehicle 42. Specifically, the use of the portable device 10 is permitted or prohibited based on the relative positional relationship with the signal generator 30.
That is, when the portable device 10 is close to the signal generator 30 embedded in the driver's seat 44, it can be determined that the portable device 10 is used by the driver, and whether the side brake is ON or OFF. Accordingly, whether or not the portable device 10 can be used is controlled. When the side brake is ON, it is determined that there is no problem in traffic safety even if the driver uses the portable device 10, and the use of the portable device 10 is permitted. When the side brake is OFF, it is determined that there is a traffic safety problem when the driver uses the portable device 10, and the use of the portable device 10 is prohibited.

  In this way, the availability of the portable device 10 is controlled based on the relative positional relationship of the portable device 10 with respect to the signal generator 30. Here, the space that is the use restriction range A of the portable device 10 may be a range of about 20 to 50 cm in radius with the signal generator 30 as the center. If the range is excessively widened, use of the portable device 10 is prohibited even if an occupant in the front passenger seat 45 or an occupant seated in the rear seat 46 directly behind the driver's seat 44 tries to use the portable device 10. In addition, if the range is too narrow, the driver intentionally puts it on a position away from the signal generator 30, for example, on the dashboard, so that it is outside the use restriction range A, and the use of the portable device 10 is permitted. This is also not preferable. In order to prevent such a situation as much as possible, it is necessary to define the use regulation range A to be an appropriate region. As one of the measures, the position of the signal generator 30 embedded in the seat 44a of the driver's seat 44 can be set as far as possible in front of the vehicle 41 and on the opposite side of the passenger seat.

  In the present embodiment, it is possible to clearly distinguish the case where the driver is using and the case where the passenger is using it. Therefore, it is possible to allow the passenger to use the device while prohibiting the use (operation, viewing of video, etc.) of the portable device 10 during driving by the driver, and use of the portable device 10 in the interior 42 of the vehicle. It is possible to achieve both safety and convenience.

The following modifications can be considered for the above-described embodiment.
In the present embodiment, the stop state of the vehicle 41 is determined based on the parking signal, but a modified example in which vehicle speed pulses are used together is conceivable. That is, the state of the vehicle is determined by the parking signal and the vehicle speed pulse. With this configuration, the determination accuracy can be improved.
In the case where the portable device 10 is a navigation device, a vehicle speed pulse is naturally input to the fixed device 20. In the case of this modification, the vehicle state is determined by adding the input vehicle speed pulse to the parking signal.
Here, if the determination based on the parking signal (for example, the stopped state) matches the determination based on the vehicle speed pulse (for example, the stopped state), the availability of the movable device 10 may be controlled based on the result. On the other hand, if the determination results of both do not match, the following processing is performed.
That is, when it is determined that the parking brake is ON by the parking signal and the vehicle is traveling due to the vehicle speed pulse, the portable device is assumed to be not stopped (running) based on the input of the vehicle speed pulse. Whether or not the portable device 10 can be used is controlled according to the position 10. Further, when it is determined that the parking brake is OFF by the parking signal and the vehicle is stopped by the vehicle speed pulse, the use of the portable device 10 is used in the same manner as when the parking brake in the above-described embodiment is OFF. The availability is controlled.

In the present embodiment, the position of the portable device 10 in the vehicle 42 is estimated by measuring the signal strength (radio wave strength), but the specifics of the portable device 10 and the signal generator 30 are determined from the signal strength. It is also conceivable to calculate a typical separation distance.
As another modification, it is also conceivable to use a signal generator (not shown) that emits an infrared signal instead of the signal generator 30 that transmits a radio signal. In this case, the receiving unit 11 of the portable device 10 is configured as a light receiving unit (not shown) that detects the presence / absence of infrared light received from a signal generator (not shown). Such a signal generator 30 may be installed at a lower surface of a steering device (not shown) so that infrared light is emitted from the lower side of the handle 47 toward the seat 44a of the driver's seat 44. It is also conceivable that a plurality of signal generators (not shown) that emit light toward the driver's seat 44 are installed in the vehicle interior 42.
Furthermore, as another modification, it is conceivable to grasp the position of the portable device 10 in the vehicle 42 by using an ultrasonic distance measuring device for measuring the distance between two objects.

In the present embodiment, the signal intensity (radio wave intensity) transmitted from the signal generator 30 installed in the driver's seat 44 is measured, and the use of the portable device 10 is prohibited when a predetermined threshold is reached. However, it is also conceivable to configure the reverse. That is, the signal generator 30 is installed in the passenger seat 45 or the rear seat 46, the signal intensity (radio wave intensity) transmitted from the signal generator 30 is measured, and when the predetermined threshold value is reached, the portable device 10 Is allowed. On the other hand, when the predetermined threshold value is not reached, the use of the portable device 10 is prohibited.
In such a modification, when the signal generator (not shown) that emits the infrared signal described above is used, the light receiving surface (not shown) of the portable device 10 is difficult to receive due to dirt or the like due to long-term use. The situation that is unfavorable for traffic safety is considered. Therefore, if the portable device 10 is allowed to be used when a signal is received, the above situation can be prevented. That is, if the light receiving surface (not shown) of the portable device 10 becomes dirty, the use of the portable device 10 is likely to be prohibited. However, the initial use of the portable device 10 is appropriately performed by cleaning the light receiving surface (not shown). Return to regulation.

  It is also conceivable that the signal generator 30 is installed not only on the seat 44 a of the driver seat 44 but also on the seat 45 a of the passenger seat 45. It is possible to distinguish between a case where the driver intends to use the portable device 10 placed on the seat 45 a of the passenger seat 45 and a case where a passenger sitting on the passenger seat 45 intends to use the portable device 10. It becomes. In other words, the signal intensity of a signal generator (not shown) installed in the passenger seat 45 is focused on the phenomenon that the signal intensity increases in the former case but decreases in the latter case.

In the present embodiment, the signal generator 30 that emits a non-directional radio signal is used. However, the signal generator 30 may be provided in the fixed device 20 if appropriate directivity can be obtained. Conceivable.
Note that, as described above, in the case where the portable device 10 is a video device that displays various videos, the case where the selection of whether to permit or prohibit the use of the video device has been described. It can be considered that the same can be applied to the case where the function is limited so that only output is possible.
