Description

FIELD OF THE INVENTION

The present invention relates to position detection devices that activate or deactivate a second apparatus based on the detected presence of a first apparatus, and methods thereof.

BACKGROUND

Modern vehicles include many electronic systems and features that provide an increased level of convenience to the driver and passengers. One such system is the wireless control of and communication between a mobile phone and a hands-free device used, for example, in a vehicle when the vehicle is moving. Bluetooth is a common example of such a wireless protocol. The wireless device can be integrated into a vehicle's audio environment and programmed to automatically connect to a mobile phone when the mobile phone is in or near the vehicle. As wireless devices increase in operating range, mobile phones may remain connected to the wireless device after exiting the vehicle. This decreases the perceived quality and convenience of the wireless device in the vehicle because the wireless device will continue to function as if the mobile phone is still in the vehicle. This can also create privacy issues as the conversation can continue to be heard by any within the vehicle.

For example, this may occur when the driver has started the vehicle and has received or placed a call while standing outside of the vehicle. If the driver stands too close the vehicle, the hands-free system can activate. The mobile phone user cannot communicate with the phone and must switch back to handset mode manually or enter the vehicle. The instances of this happening can be more frequent in urban areas where, for example, a vehicle is temporarily parked for a driver or passenger to enter a shop or convenience store while other passengers remain in the vehicle.

SUMMARY

Disclosed herein are embodiments of position detection devices for vehicles and methods of position detection. One embodiment of a detection device comprises a wireless device inside a vehicle, a mobile communication device paired to the wireless device, such that the wireless device automatically activates when it senses the mobile communication device within an operable range of the wireless device, a position sensing system configured to generate an output indicative of the mobile communication device's presence within the vehicle and a controller responsive to the output and configured to deactivate the wireless device when the output indicates that the mobile communication device's presence is not within the vehicle.

DETAILED DESCRIPTION

Referring to FIG. 1, an embodiment of a detection system 10 for detecting the presence of a device relative to a vehicle 15 is illustrated. The detection system 10 comprises a wireless device 20 located inside a vehicle 15. A mobile communication device 22 is paired to the wireless device 20, such that the wireless device 20 automatically activates when it senses the mobile communication device 22 within an operable range 32 of the wireless device 20. A position sensing system 24 is configured to generate an output indicative of the mobile communication device's presence 22 within the vehicle 15. A controller 26 is responsive to the output and is configured to deactivate the wireless device 20 when the output indicates that the mobile communication device's presence 22 is not within the vehicle 15.

The detection system 10 can be used with any type of vehicle 15. A sedan is shown in the figures for illustrative purposes only and is not meant to be limiting. The wireless device 20 is, for example, a Bluetooth device for use with a mobile communication device 22 such as a mobile phone. Wireless devices 20 such as those using the Bluetooth services generally require authentication, and as such require pairing with the mobile communication device 22 before they allow the mobile communication device 22 such as a mobile phone to use the Bluetooth service.

The wireless device 20 can be located in the vehicle 15 in any location desired or required by the manufacturer or installer. Typically, the wireless device 20 is located in the passenger compartment of the vehicle 15. As a non-limiting example, the wireless device 20 may be installed within the instrument panel of the vehicle 15, with a user interface mounted on the dashboard of the vehicle 15 within reach of the driver. The wireless device 20 can be integrated into the audio system of the vehicle 15, so that the person on the other end of the mobile communication device 22 is heard through the speakers of the vehicle 15 and the driver or passenger can speak into a vehicle mounted microphone.

The position sensing system 24 can comprise, for example, a mobile transmitter 28 and a receiver 30. The mobile transmitter 28 can be transported by the mobile communication device 22 user. For example, the mobile transmitter 28 may be a key fob also used to operate the vehicle 15. It is also contemplated that the mobile transmitter 28 be incorporated into the mobile communication device 22 itself, as shown in FIG. 2.

The receiver 30 can be located within the vehicle 15 in any location desired or required by the manufacturer or installer. The mobile transmitter 28 relays its position, which is indicative of the position of the mobile communication device 22, to the receiver 30. For example, the mobile transmitter 28 can transmit signals and the receiver 30 can employ a vehicle antenna to receive the signals and can triangulate its position based upon the signals. This can be reversed, with the receiver 30 employing the vehicle antenna to transmit the signals and a mobile “transmitter” 28 receiving the signals, triangulating the position based upon the signals, and transmitting a signal back to the receiver 30 indicative of the position. The position can be independently determined with, for example, a GPS portable navigation device and transmitted to either the receiver 30 or the mobile transmitter 28. Additionally, multiple receivers 30 may be installed in the vehicle to facilitate triangulation of the position of the mobile transmitter 28. Those with skill in the art will recognize that these are provided by way of example and not limitation, and other position sensing systems can be used as desired or required.

The mobile transmitter 28 can communicate with the receiver 30 with electronic communication or with wireless communication. Examples of wireless communication are radio frequency broadcast transmission and infra red transmissions. These are provided by way of example and not limitation and other means of communication known to those skilled in the art can be used. As another example, the wireless device 20 signal strength might also be used to determine the location of the mobile communication device 22. A reference or baseline strength when the mobile communication device 22 is within the vehicle can be recorded by the system and signal strengths below this level could indicate the mobile communications device 22 is outside of the vehicle 15.

The output from the position sensing system 24 is transmitted to the controller 26, which is responsive to the output. The controller 26 can be, for example, a central processing unit. The controller 26 can be located in the vehicle 15 in any location desired or required by the manufacturer or installer. The position sensing system 24 can communicate with the controller 26 with electronic communication or with wireless communication, depending on the type of system used. For example, the controller 26 can be located within the vehicle 15 and hardwired to the controller 26 for electronic communication. The controller 26 can be located within the vehicle 15 and set up for wireless communication with the receiver 30. Other means of communication known to those skilled in the art can also be used. It is also contemplated that the controller 26 is a portable device that can be carried with the user of the mobile communication device 22.

The controller 26 is programmed and configured to deactivate the wireless device 20 if the output of the position sensing system 24 indicates that the mobile communication device 22 is no longer within the vehicle 15. If the output indicates that the mobile communication device 22 is within the vehicle, the wireless device 20 is allowed to activate as it normally would. Deactivate as used herein means to interrupt operation of the wireless device 20 with the mobile communication device 22. When this occurs, the mobile communication device 22 must be used without the wireless device 20. As non-limiting examples, interruption can be due to authentication interruption between the wireless device 20 and the mobile communication device 22, disabling the hands-free function, or can be interruption of power to the wireless device 20.

FIG. 3 illustrates the operating range 32 of the wireless device 20 with respect to the vehicle 15. When the receiver 30 detects from the mobile transmitter 28 that the mobile communication device 22 is within the vehicle 15, the output to the controller 26 indicates as such and the controller 26 does not deactivate the wireless device 20. Accordingly, the wireless device 20 and the mobile communication device 22 operate as configured.

FIG. 4 illustrates the same operating range 32 of the wireless device 20 with respect to the vehicle 15 as FIG. 3. However, as shown, the receiver 30 detects from the mobile transmitter 28 that the mobile communication device 22 is not in the vehicle 15. The receiver 30 outputs to the controller 26 an indication that the mobile communication device 22 is outside of the vehicle 15. In response, the controller 26 deactivates the wireless device 20 even though the mobile communication device remains in the operable range 32.

The controller 26 may be further configured to provide a warning to a user of the mobile communication device 22 that the wireless device 20 has been deactivated. The warning may be an audio signal, a visual signal, or both. For example, the warning may be a beep, or a recorded voice. The signal may be a light that turns on or flashes, or an indication on a display of the mobile communication device 22. These are provided by way of example and are not meant to be limiting. Other warning signals known to those skilled in the art may be used. The warning may be emitted directly from the controller 26, or may be provided by the mobile transmitter 28 or mobile communication device 22 after receiving an output from the controller 26.

The controller 26 can be further configured to reactivate the wireless device 20 if the controller 26 receives output from the position sensing system 24 that indicates the mobile communication device's presence 22 is within the vehicle 15. This would allow a user of the mobile communication device 22 to continue a conversation, for example when filling up with gas at a gas station, without any interruption.

In another embodiment of the position detection device, the position sensing system 24 may comprise more than one mobile transmitter. As shown in FIG. 5, the position sensing system 24 comprises mobile transmitter 28 and mobile transmitter 28′. The wireless device 20 can be paired with more than one mobile communication device 22, 22′, with each of the mobile communication devices 22, 22′ associated with a mobile transmitter 28, 28′. For example, a driver of the vehicle 15 may transport both mobile communication device 22 and a key fob having the mobile transmitter 28. Another potential driver of the same vehicle 15, such as another member of the driver's family, may transport mobile communication device 22′ and a key fob with mobile transmitter 28′.

The receiver 30 can be configured to generate an output indicative of each mobile communication device's presence 22, 22′ within the vehicle 15 and communicate each output to the controller 26. The controller 26 can be configured to deactivate the wireless device 20 for each of the mobile communication devices 22, 22′ having an associated output indicative that the mobile communication device's 22, 22′ presence is not within the vehicle 15.

As a non-limiting example, a situation can arise where a driver and a passenger each have a key fob with a mobile transmitter 28, 28′ that operates a shared vehicle 15, and each have a mobile communication device 22, 22′ paired with the wireless device 20 of the vehicle 15. If both driver and passenger are in the vehicle, the wireless device 20 will typically only authenticate with one of the mobile communication devices 22, 22′ at a time, or prioritize one mobile communication device 22, 22′ over the others. Typically, the driver's mobile communication device 22 will take precedence over the passenger's mobile communication device 22′. This preference can be a function of the mobile communication devices 22, 22′. For example, one mobile communication device 22 or 22′ can be manually turned off. The preference may be a function of the wireless device 20, wherein the wireless device 20 is programmed with the preferences. These are provided as examples and are not meant to be limiting.

If the driver exits the vehicle with the mobile communication device 22, the position sensing system 24 will sense the absence of the driver's mobile communication device 22 from within the passenger compartment, and communicate an output indicative of the absence of the driver's mobile communication device 22 to the controller 26, which will deactivate the wireless device 20 from operating with the driver's mobile communication device 22. At that time, if the passenger remains in the vehicle with the passenger's mobile communication device 22′, the controller 26 can be programmed to activate the wireless device 20 to operate with the passenger's mobile communication device 22′. If the driver reenters the vehicle 15 while still using the driver's mobile communication device 22, it is contemplated that the controller 26 can be programmed to reactive the wireless device 20 with the driver's mobile communication device 22 and deactivate the wireless device 20 from the passenger's mobile communication device 22′. Alternatively, as desired or required, the controller 26 can be programmed to keep the wireless device 20 deactivated with the driver's mobile communication device 22 and maintain activation of the wireless device 20 with the passenger's mobile communication device 22′ if the passenger continues to use the passenger's mobile communication device 22′ in conjunction with the wireless device 20 at the time the driver reenters the vehicle 15.

Also disclosed herein are methods of detecting a presence of a device within a vehicle. One such method for detecting the presence of a device within a vehicle comprises the following steps. The reference numerals refer to FIGS. 1-4, while the steps are shown in FIG. 6. In step S1, a wireless device 20 located within the vehicle 15 is paired with a mobile communication device 22 such that the wireless device 20 is activated when the mobile communication device 22 is within an operable range 32 of the wireless device 20.

In step S2, the mobile communication device's 22 presence is detected with a position sensing system 24. An output is generated indicative of the mobile communication device's 22 presence in step S3. The output indicates whether the mobile communication device 22 is inside the vehicle or outside of the vehicle 15. The output is communicated to a controller 26 responsive to the output in step S4. In step S5, when the output indicates that the mobile communication device 22 is outside of the vehicle 15, the controller 26 deactivates the wireless device 20 so that the wireless device 20 no longer communicates with the mobile communication device 22.

As discussed above, the position sensing system 24 can comprise, for example, a mobile transmitter 28 and a receiver 30. The mobile transmitter 28 can be transported by the mobile communication device 22 user. For example, the mobile transmitter 28 may be a key fob also used to operate the vehicle 15. It is also contemplated that the mobile transmitter 28 be incorporated into the mobile communication device 22 itself, as shown in FIG. 2.

The receiver 30 can be located within the vehicle 15 in any location desired or required by the manufacturer or installer. The mobile transmitter 28 relays its position, which is indicative of the position of the mobile communication device 22, to the receiver 30. For example, the mobile transmitter 28 can transmit signals and the receiver 30 can employ a vehicle antenna to receive the signals and can triangulate its position based upon the signals. This can be reversed, with the receiver 30 employing the vehicle antenna to transmit the signals and a mobile “transmitter” 28 receiving the signals, triangulating the position based upon the signals, and transmitting a signal back to the receiver 30 indicative of the position. The position can be independently determined with, for example, a GPS portable navigation device and transmitted to either the receiver 30 or the mobile transmitter 28. Additionally, multiple receivers 30 may be installed in the vehicle to facilitate triangulation of the position of the mobile transmitter 28. Those with skill in the art will recognize that these are provided by way of example and not limitation, and other position sensing systems can be used as desired or required.

The mobile transmitter 28 can communicate with the receiver 30 with electronic communication or with wireless communication. Examples of wireless communication are radio frequency broadcast transmission and infra red transmissions. These are provided by way of example and not limitation and other means of communication known to those skilled in the art can be used.

The method may further comprise step S6, providing a warning to a user of the mobile communication device 22 that the wireless device 20 has been deactivated. The warning may be an audio signal, a visual signal, or both. For example, the warning may be a beep, or a recorded voice. The signal may be a light that turns on or flashes, or an indication on a display of the mobile communication device 22. These are provided by way of example and are not meant to be limiting. Other warning signals known to those skilled in the art may be used. The warning may be emitted directly from the controller 26, or may be provided by the mobile transmitter 28 or mobile communication device 22 after receiving an output from the controller 26.

Step S7 can be reactivating the wireless device 20 if the controller 26 receives output from the position sensing system 24 that indicates the mobile communication device's 22 presence is within the vehicle 15 when the mobile communication device 22 reenters the vehicle 15. This would allow a user of the mobile communication device 22 to continue a conversation, for example when filling up with gas at a gas station, without any interruption.

Another embodiment of a method of detecting a presence of a device, illustrated in FIG. 7, can further comprise a position sensing system 24 having more than one mobile transmitter 28, 28′, as discussed with reference to FIG. 5. Pairing S10 of the wireless device 20 can occur with more than one mobile communication device 22, 22′. In step S11, each mobile communication device 22, 22′ can be associated with a mobile transmitter 28, 28′. Association of the mobile communication devices 22, 22′ and mobile transmitters 28, 28′ can be accomplished, for example, by programming the wireless device 20 to associate mobile communication device 22 with mobile transmitter 28 and mobile communication device 22′ with mobile transmitter 28′. Alternatively, mobile communication device 22 can become associated with mobile transmitter 28 by being manufactured as an integral unit, and mobile communication device 22′ can become associated with mobile transmitter 28′ by being manufactured as an integral unit. In step S12, the presence or absence of each mobile communication device 22, 22′ is detected. Generating S13 the output includes generating output indicative of each mobile communication device's presence 22, 22′ within the vehicle 15. The output is communicated to a controller 26 responsive to the output in step S14.

In step S15, deactivating the wireless device 20 can include deactivating the wireless device 20 for each of the mobile communication devices 22, 22′ when the output is indicative of the mobile communication device's absence 22, 22′ from within the vehicle 15.

As a non-limiting example, a situation can arise where a driver and a passenger each have a key fob with a mobile transmitter 28, 28′ that operates a shared vehicle 15, and each have a mobile communication device 22, 22′ paired with the wireless device 20 of the vehicle 15. If both driver and passenger are in the vehicle, the wireless device 20 will typically only authenticate with one of the mobile communication devices22, 22′ at a time. Typically, the driver's mobile communication device 22 will take precedence over the passenger's mobile communication device 22′. This preference can be a function of the mobile communication devices 22, 22′. For example, one of the mobile communication devices 22 or 22′ can be manually turned off. The preference may be a function of the wireless device 20, wherein the wireless device 20 is programmed with the preferences. These are provided as examples and are not meant to be limiting.

If the driver exits the vehicle 15 with the driver's mobile communication device 22, the position sensing system 24 will communicate to the controller 26, which will deactivate the wireless device 20 from operating with the driver's mobile communication device 22. At that time, if the passenger remains in the vehicle, the controller 26 can be programmed to activate the wireless device 20 to operate with the passenger's mobile communication device 22′. If the driver reenters the vehicle 15 while still using mobile communication device 22, it is contemplated that the controller 26 can be programmed to reactive the wireless device 20 with the driver's mobile communication device 22 and deactivate the wireless device 20 from the passenger's mobile communication device 22′. Alternatively, as desired or required, the controller 26 can be programmed to keep the wireless device 20 deactivated with the driver's mobile communication device 22 and maintain activation of the wireless device 20 with the passenger's mobile communication device 22′ if the passenger is on the mobile communication device 22′ at the time the driver reenters the vehicle 15.
