Background technique

Today's technology is advancing day by day. For example, the key of the traditional vehicle is to open the door or engine of the vehicle mechanically, but the key of the current vehicle is mostly an inductive key. When the user approaches the vehicle , if the vehicle senses the induction key, it can automatically open and lock the door or engine of the vehicle, so as to reduce the trouble of the user when using the vehicle.

Moreover, today's inductive keys mostly use radio frequency (Radio Frequency, RF) technology or radio frequency identification (Radio Frequency Identification, RFID) technology. Both of these two technologies have two corresponding tags and identifiers. When the identifier senses the tag, the vehicle can automatically open and lock the vehicle door or engine. However, both of these two technologies are line of sight (LOS) technologies, so they are more susceptible to interference and increase the inconvenience of users. In addition, if it is necessary to perform different connection relationships under different distance conditions, the current technology needs to use different connection devices to perform different connection relationships respectively, which will increase the use cost and use space.

Detailed ways

It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

Please refer to FIG. 1 . FIG. 1 is a flowchart of the steps of the bluetooth system of the present invention to measure the distance value to perform actions. As shown in FIG. 1 , in the present invention, step 100 can be performed first, that is, a preset distance value is set. Wherein, the preset distance value can be set, for example, when the bluetooth system is manufactured, or the user can set the preset distance value through an input device. Then, step 200 can be performed, that is, to measure the distance value between the vehicle and the handheld device. Among them, the vehicle can be, for example, a two-wheel vehicle, a four-wheel vehicle, or a vehicle with more than two wheels. ATV or utility vehicle. Also, the handheld device may be, for example, a mobile phone or a key.

In other words, the present invention measures and obtains the distance value between the vehicle and the handheld device through the Bluetooth system, and the Bluetooth system includes at least a first Bluetooth device and a second Bluetooth device, and the first Bluetooth device and the second Bluetooth device One of the Bluetooth devices is, for example, disposed on a vehicle, and the other is, for example, disposed on a handheld device. Moreover, the first bluetooth device and the second bluetooth device are paired with each other. Wherein, since any bluetooth device has its own address code, the two bluetooth devices can be paired with each other through mutual pairing of the two address codes. In addition, the first bluetooth device and the second bluetooth device can be connected to each other in a point-to-point manner, so that data transmission does not need to go through a third party, thereby increasing the security and convenience of transmission and pairing. In addition, the Bluetooth system can use frequency hopping technology and encryption by Advanced Encryption Standard-128 (AES-128) to further increase the security of transmission and pairing.

Please continue to refer to FIG. 2 . FIG. 2 is a flow chart of the steps for obtaining the distance value by the Bluetooth system of the present invention. As shown in FIG. 2 , the present invention first performs step 201 when obtaining the distance value, that is, the first bluetooth device transmits the ranging signal to the second bluetooth device, so that the second bluetooth device can know the signal strength of the ranging signal. Wherein, any one of the first bluetooth device and the second bluetooth device transmits a signal to the other at intervals, so this signal can be used as a distance measuring signal. Wherein, the interval time may be, for example, three seconds, five seconds, ten seconds or other suitable time. In addition, the ranging signal can also be, for example, a signal with other information, or a signal that is only used to measure the signal strength for ranging. If the ranging signal is a signal with other information, after receiving the ranging signal, the second Bluetooth device can not only know the signal strength of the ranging signal, but also transmit other information in the ranging signal to the The second bluetooth device is connected to each other or the processor of the second bluetooth device itself to further process this other information. In addition, the second Bluetooth device can obtain the signal strength of the ranging signal, for example, by using a signal strength measuring device.

Then, when the second bluetooth device receives the ranging signal and knows the signal strength of the ranging signal, it can proceed to step 202, that is, the second bluetooth device obtains or determines the first bluetooth signal according to the strength of the ranging signal. The distance value between the device and the second Bluetooth device. For example, the second bluetooth device may have a comparison table of signal strength and distance value. When the second bluetooth device knows the signal strength, it can obtain the corresponding distance value by looking up the table. Alternatively, the second bluetooth device can, for example, have a built-in linear or non-linear relationship function between signal strength and distance value. When the second bluetooth device knows the signal strength, it can substitute the signal strength into the relationship function, so as to The distance value between the first bluetooth device and the second bluetooth device is obtained through calculation. Wherein, because one of the first Bluetooth device and the second Bluetooth device is located on the vehicle, and the other is located on the handheld device, the distance between the first Bluetooth device and the second Bluetooth device is equal to the distance between the vehicle and the handheld device. The distance value of the device.

In other words, after the second bluetooth device knows the distance value between the vehicle and the handheld device, it can optionally proceed to step 203, that is, the second bluetooth device transmits the distance value between the vehicle and the handheld device to the first bluetooth device, so as to Both the first bluetooth device and the second bluetooth device can know the distance value. In addition, the second bluetooth device and the first bluetooth device can also transmit signals to each other, so that both the first bluetooth device and the second bluetooth device can measure the signal strength of the signal, and then Know or determine the distance value between the vehicle and the handheld device respectively. Afterwards, for example, by transmitting the learned distance value to another bluetooth device, it is possible to further confirm whether the distance value is correct. For example, if the difference between the distance values obtained by the first bluetooth device and the second bluetooth device is too large, step 200 may be performed again. On the contrary, if the distance values obtained by the first bluetooth device and the second bluetooth device are similar or equal, then the average value of the two distance values can be taken as the distance value between the vehicle and the handheld device, or one of them can be chosen arbitrarily. A distance value is the distance value between the vehicle and the handheld device. Wherein, the judgment of whether the gap of the distance value mentioned here is too large can be defined separately according to the application purpose of the distance value.

After measuring the distance value between the vehicle and the handheld device, step 300 can be performed, that is, comparing the distance value. For example, in step 300, one or both of the first bluetooth device and the second bluetooth device may respectively compare the preset distance value and the distance value between the vehicle and the handheld device, or, for example, Compare the distance values between the vehicle and the handheld device at different times. Moreover, regardless of whether the step 300 is comparing the distance value with a preset distance value or comparing the distance values at different times, a comparison result can be obtained. Then, one or both of the first Bluetooth device and the second Bluetooth device can perform step 400 according to the comparison result, that is, perform actions. Wherein, the executed action may be, for example, establishing a connection relationship between the first Bluetooth device and the second Bluetooth device, or it may be, for example, alerting the user. In addition, the execution action can also be, for example, sending a message to the vehicle or the handheld device, so as to enable the vehicle or the handheld device to enable or disable its specific function.

Therefore, because the bluetooth device will send a signal to another bluetooth device paired with it at intervals, the bluetooth system can measure the distance between the two bluetooth devices by means of the constantly sent signal. In addition, the bluetooth device can also specially transmit a distance measurement signal to perform the action of measuring the distance value. Wherein, the interval time may be, for example, the time defined in the Bluetooth technology protocol (IEEE 802.15), or any time set by the user or the manufacturer. For example, the interval time may be three seconds, five seconds, ten seconds or other suitable time.

Please refer to FIG. 4 to FIG. 5 in succession. FIG. 4 is a system block diagram of the Bluetooth vehicle control system of the present invention, and FIG. 5 is a system block diagram of the handheld Bluetooth system for controlling the vehicle of the present invention. Wherein, the Bluetooth vehicle control system and the handheld Bluetooth system can be paired with each other, and one of them can be, for example, the aforementioned first Bluetooth device, and the other can, for example, be the aforementioned second Bluetooth device. As shown in FIGS. 4 to 5 , wherein the Bluetooth vehicle control system 500 can be located on the vehicle, for example, the Bluetooth vehicle control system 500 can be located on the vehicle rearview mirror, front dashboard, glove box or other devices on the carrier. In addition, the handheld Bluetooth system 600 can be, for example, a key or built into a handheld device such as a mobile phone. In addition, the present invention can provide power to the Bluetooth vehicle control system 500 and the handheld Bluetooth system 600, for example, through a power supply method, wherein the power supply methods can be, for example, solar power, hydroelectric power, thermal power, wind power Power supply, battery power supply, power supply or vibration generating power supply, wireless charging power supply or other methods that can generate power.

In other words, the Bluetooth vehicle control system 500 may, for example, have a vehicle Bluetooth device 510 and a vehicle control device 520 electrically connected to each other. Wherein, the vehicle-mounted Bluetooth device 510 may include, for example, a Bluetooth transceiver device 511 , a processor 512 , and a memory unit 513 and a warning device 514 electrically connected to the processor 512 . The vehicle control device 520 can be arranged on the vehicle, for example, and the vehicle control device 520 can, for example, include a vehicle control unit 521 and an input device 522, an output device 523 and an imaging device electrically connected to the vehicle control unit 521. 525. Wherein, the bluetooth transceiver device 511 can be wirelessly connected with an external device, for example, by bluetooth technology, to receive a signal transmitted by the external device. Moreover, the external device can be, for example, the handheld Bluetooth system 600 paired with the Bluetooth vehicle control system 500 . In addition, the vehicle control unit 521 is disposed on the vehicle and controls the vehicle.

In addition, the processor 512 is electrically connected to the Bluetooth transceiver device 511 and the vehicle control unit 521 . Wherein, if the Bluetooth vehicle control system 500 is the aforementioned second Bluetooth system, when the Bluetooth transceiver device 511 transmits the received signal to the processor 512, the processor 512 first measures the signal strength of the signal, and uses Based on the signal strength, the distance between the external device and the vehicle is determined. Next, the processor 512 compares the distance value with a preset distance value to obtain a comparison result. Wherein, the preset distance value can be stored, for example, in the memory unit 513 , and the memory unit 513 is electrically connected to the processor 512 to provide the preset distance value to the processor 512 . Alternatively, the vehicle control unit 521 can be electrically connected to the input device 522, so that the user can use the input device 522 to set a preset distance value, and the preset distance value is then transmitted to the processor 512 via the vehicle control unit 521 middle. In addition, the preset distance value may be approximately between 1 meter and 100 meters, for example.

After obtaining the comparison result of the distance value, the processor 512 can, for example, use the comparison result to send an action signal to the vehicle control unit 521 and the external device, so that the vehicle control unit 521 and the external device can communicate with each other through the action signal. Perform an action. For example, when the comparison result is that the preset distance value is greater than the distance value between the vehicle and the external device, the external device may, for example, establish a connection relationship with the vehicle control unit 521, so that the vehicle control unit 521 controls the vehicle selectivity Take an action. Wherein, this action may be, for example, to enable a function, and this function may be, for example, disabling the anti-theft system of the vehicle, transmitting the signal of the vehicle to an external device, opening the equipment inside the vehicle, unlocking the doors or the engine of the vehicle, or , to alert the user. In addition, when the vehicle activates this function, the vehicle can directly perform actions corresponding to this function, or open an external device to selectively perform actions corresponding to this function. For example, the vehicle control unit 521 can control the vehicle to unlock the equipment inside the vehicle, so that an external device can be connected to the vehicle control unit 521 to unlock the equipment inside the vehicle. In other words, if the vehicle control unit 521 does not activate the function of unlocking the internal equipment of the vehicle, the external device cannot command the vehicle control unit 521 to open the internal equipment of the vehicle.

In addition, if the vehicle enables the controllable function, the external device can establish a connection relationship with the vehicle control unit 521 . After the external device establishes a connection relationship with the vehicle control unit 521, the vehicle control unit 521 can, for example, control the camera device 525 to capture an image and send it back to the vehicle control unit 521, and then transmit the image via the processor 512 of the vehicle Bluetooth device 510. to the Bluetooth transceiver 511, so as to send the image to an external device via the Bluetooth transceiver 511. In addition, if the action is to warn the user, the processor 512 can, for example, send a warning signal to the built-in warning device 514 of the vehicle-mounted Bluetooth device 510, so as to make the warning device 514, which is a light-emitting component, emit light or flash to warn the user. Alternatively, the warning device 514 , such as a sound component, can make a sound to warn the user. In addition, the processor 512 may also send a warning signal to the vehicle control unit 521, and the vehicle control unit 521 sends the warning signal to the output device 523 after receiving the warning signal, so that the output device 523 outputs the warning signal. Wherein, the warning signal can be, for example, a sound signal, a light signal or displayed on the screen of the output device 523 .

In addition, the handheld Bluetooth system 600 may include, for example, a Bluetooth transceiver device 601 , a processor 602 , a memory unit 603 electrically connected to the processor 602 , an input device 604 and an output device 605 . Wherein, the bluetooth transceiver device 601 can be wirelessly connected to the vehicle via bluetooth technology for receiving a signal transmitted by the vehicle. Also, the vehicle may have, for example, a Bluetooth vehicle control system 500 paired with a handheld Bluetooth system 600 .

In addition, the processor 602 is electrically connected to the Bluetooth transceiver device 601. If the handheld Bluetooth system 600 is the aforementioned second Bluetooth device, then when the Bluetooth transceiver device 601 transmits the received signal to the processor 602, the processor 602 first Measure the signal strength of this signal, and use this signal strength to determine and obtain the distance value between the handheld device and the vehicle. Next, the processor 602 compares the distance value with a preset distance value to obtain a comparison result. Wherein, the preset distance value can be stored in the memory unit 603 , for example, when the processor 602 needs to compare the distance value with the preset distance value, the memory unit 603 provides the preset distance value to the processor 602 . Alternatively, let the user use the input device 604 to set a preset distance value, and the preset distance value is then transmitted to the processor 602 through the input device 604 . Wherein, the preset distance value may be approximately between 1 meter and 100 meters, for example.

After obtaining the comparison result of the distance value, the processor 602 uses the comparison result to, for example, send an action signal to the vehicle and the output device 605, so that the vehicle performs an action through the action signal, or the output device 605 outputs a warning signal or other signals through this action signal. For example, when the comparison result is that the preset distance value is greater than the distance value between the handheld device and the vehicle, the handheld device can, for example, establish a link relationship with the vehicle to control the vehicle to perform an action, or to control the vehicle It has a function of opening. Wherein, this action or function may be, for example, disabling the anti-theft system of the vehicle, transmitting the signal of the vehicle to the handheld device, opening the equipment inside the vehicle, or unlocking the doors or the engine of the vehicle. In addition, the processor 602 can also, for example, send a warning signal to the output device 605, so as to make the output device 605 emit light, flash light, emit sound, display graphics, display text, display images or vibrate to warn the user. In addition, the output device 605 can also output a warning signal to warn or remind the user. Wherein, the output device 605 can be, for example, a light source, a speaker, a screen, a vibrating device, or a combination of the above components. Moreover, the screen can display graphics, text, images or other objects that can be displayed on the screen, for example.

Please continue to refer to FIG. 3 . FIG. 3 is a flow chart of the implementation steps of the method for managing the carrier using the Bluetooth system of the present invention. As shown in Figures 1 to 5, the method for managing vehicles using the Bluetooth system of the present invention is, for example, first setting a first preset distance value and a second preset distance value in step 100, wherein the first preset distance value less than the second preset distance value. Then, measure and obtain the distance value between the vehicle and the handheld device in step 200, and then compare the measured distance value with the first preset distance value and the second preset distance value in step 300 to obtain 1. Compare the results. Wherein, the comparison result is that the distance value is greater than the second preset distance value, the distance value is between the first preset distance value and the second preset distance value, or the distance value is smaller than the first preset distance value. Finally, different actions are performed in step 400 according to the different comparison results in step 300 . For example, when the comparison result is that the distance value is greater than the second preset distance value, then because the bluetooth device will send a message to another bluetooth device that is paired with it at an interval, the action performed It can be, for example, to put the vehicle in a waiting state. And when the comparison result is that the distance value is between the first preset distance value and the second preset distance value, the action to be executed may be, for example, that the vehicle activates the second function. In addition, when the comparison result is that the distance value is less than the first preset distance value, the action to be executed may be, for example, that the vehicle activates the first function.

Specifically, the method for managing a vehicle using the Bluetooth system of the present invention may, for example, firstly perform step 210, that is, obtain the first preset distance value, the second preset distance value, and the distance value between the vehicle and the handheld device. For example, step 210 may first perform step 100 to set a preset distance value, and the preset distance value may be, for example, a first preset distance value and a second preset distance value, and the second preset distance value is greater than the first preset distance value. Wherein, the first preset distance value and the second preset distance value can be pre-stored in the memory unit 513 of the vehicle-mounted Bluetooth device 510, or can be set by the user using the input device 522 of the vehicle control device 520. The first preset distance value and the second preset distance value are determined. In addition, one of the first preset distance value and the second preset distance value can also be pre-stored in the memory unit 513 of the vehicle-mounted Bluetooth device 510 , for example, and the other one can be set by the user using the input device 522 . In addition, the second preset distance value may be, for example, approximately between 50 meters and 60 meters, and the first predetermined distance value may be, for example, approximately between 2 meters and 3 meters.

After or simultaneously with step 100 , step 200 may be performed, for example, by utilizing the processor 512 of the vehicle-mounted Bluetooth device 510 to determine the distance between the vehicle and the handheld device. Wherein, the vehicle may be, for example, a two-wheel vehicle, a four-wheel vehicle or a vehicle with more than two wheels, and the handheld device may be, for example, a mobile phone or a key. Specifically, the handheld device may have a handheld Bluetooth system 600 , and the vehicle may have a Bluetooth vehicle control system 500 , and the Bluetooth vehicle control system 500 and the handheld Bluetooth system 600 are paired with each other. Therefore, the Bluetooth transceiver device 601 of the handheld Bluetooth system 600 can, for example, transmit a signal to the Bluetooth transceiver device 511 of the Bluetooth vehicle control system 500 , and after receiving the signal, the Bluetooth transceiver device 511 transmits the signal to the processor 512 . Wherein, the signal may be, for example, a signal transmitted by the Bluetooth system at intervals, or specifically a ranging signal or a connection request signal. Afterwards, the processor 512 obtains the distance value between the vehicle and the handheld device according to the signal strength of the signal. Then, the processor 512 can transmit the distance value to the Bluetooth transceiver device 601 of the handheld Bluetooth system 600 through the Bluetooth transceiver device 511 . If the Bluetooth transceiver device 601 receives the distance value, the Bluetooth transceiver device 601 transmits the distance value to the processor 602, so that the Bluetooth vehicle control system 500 and the handheld Bluetooth system 600 both know the distance value.

Then, after obtaining the distance value, the first preset distance value and the second preset distance value, the processor 512 proceeds to step 311, that is, judges whether the learned distance value is less than the first preset distance value, and if so, proceeds Step 411, that is, make the vehicle turn on the first function; if not, proceed to step 412, that is, make the vehicle turn on the second function, and when the vehicle is in the state of turning on the first function, turn off the first function again. Function. For example, in step 411, the processor 511 may send a notification signal to the handheld Bluetooth system 600 and the vehicle control unit 521, so that the vehicle control unit 521 controls the vehicle to activate the first function, so that the user can use The handheld bluetooth system 600 controls the vehicle to perform the actions of the opened functions. At this time, the handheld Bluetooth system 600 can, for example, send a connection request signal, and the processor 511 sends the connection request signal to the vehicle control unit 521, and replies a confirmation connection signal to the handheld Bluetooth system 600, so that the handheld device on the handheld The Bluetooth system 600 establishes a first connection relationship with the vehicle control unit 521 on the vehicle, so that the user can control the vehicle through the handheld device. Wherein, the first function may be, for example, unlocking the vehicle door, unlocking the engine of the vehicle, opening the equipment inside the vehicle, or other actions that the vehicle can perform. For example, when the distance between the vehicle and the handheld device is less than the first preset distance value, the vehicle control unit 521 can unlock the engine of the vehicle, and then start the engine or turn on the equipment in the vehicle. In addition, the vehicle control unit 521 may not perform any actions until the user uses the handheld device to control the vehicle control unit 521 to unlock the engine of the vehicle, start the engine or turn on the equipment in the vehicle.

In addition, when the user uses the handheld device to command the vehicle control unit 521 to perform actions, the control command can be first input, for example, through the input device 604 , and the control command can be, for example, an option displayed on the output device 605 . Then, the input device 604 sends the control command to the processor 602, and the processor 602 sends the control command to the processor 512 through the Bluetooth transceiver device 601 and the Bluetooth transceiver device 511 after receiving the control command. Afterwards, the processor 512 transmits the control command to the vehicle control unit 521 to control the vehicle.

In addition, if the processor 512 of the Bluetooth system 510 determines that the measured distance value is greater than the first preset distance value, the processor 512 can directly enable the vehicle to activate the second function through the vehicle control unit 521 (step 412), or Go to step 312 first, that is, determine whether the distance value is smaller than the second preset distance, and then decide whether to go to step 412 . Specifically, if the distance value is less than the second preset distance value, the vehicle is enabled to activate the second function through the vehicle control unit 521 (step 412); if the distance value is greater than the second preset distance value, then return to step 210, that is, obtain the distance value, the first preset distance value, and the second preset distance value again. Wherein, the second function may be, for example, disabling the anti-theft system of the vehicle, transmitting the signal of the vehicle to the handheld device, opening the equipment inside the vehicle, or other actions that the vehicle can perform. For example, the processor can establish a connection relationship between the vehicle and the handheld device, so that the vehicle can selectively perform actions. Wherein, this action may be, for example, disabling the anti-theft system of the vehicle, transmitting a signal of the vehicle to the handheld device, opening the equipment inside the vehicle, or other actions that the vehicle can perform.

In addition, the user can, for example, command the vehicle control device 521 to turn on the camera device 525 on the vehicle through the handheld device, and send the image captured by the camera device 525 back to the handheld device. After the processor 602 of the handheld device receives the image, it can send the image to the output device 605 of the handheld device, so that the user can watch the image captured by the camera device 525 of the vehicle in real time.

In addition, if in step 311, the processor 512 determines that the distance value is greater than the first preset distance value, and the vehicle is in the state of enabling the first function, the processor 512 can, for example, first pass the vehicle control unit 521 The vehicle is controlled to turn off the first function (step 413 ), and the processor 512 then determines whether the distance value is less than a second preset distance (step 312 ). Similarly, if in step 312, the processor 512 determines that the distance value is greater than the second preset distance value, and the vehicle is in the state of enabling the second function, the processor 512 can, for example, first control the vehicle through the vehicle control unit 521. After disabling the second function (step 414 ), the processor 512 additionally obtains a new distance value, a first preset distance value, and a second preset distance value (step 210 ). Wherein, one or both of the first preset distance value and the second preset distance value can maintain the original first preset distance value or the second preset distance value.
