[0048] The following is a description of exemplary embodiments of the present application in conjunction with the accompanying drawings, including various details of the embodiments of the present application to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present application. Similarly, for the sake of clarity and conciseness, the description of well-known functions and structures is omitted in the following description.

[0049] Obviously, the described embodiments are only part of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0050] It should be noted that the terminal devices involved in the embodiments of the present application may include but are not limited to mobile phones, personal digital assistants (PDAs), wireless handheld devices, tablet computers and other smart devices; display devices may include but are not limited to personal computers, televisions and other devices with display functions.

[0051] In addition, the term "and / or" in this article is only a description of the association relationship between the associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0052] In view of the existing scheme, the vehicle can be started without inserting the smart key, as long as the smart key is in the car, so the position of the smart key is not fixed, so it is often the case that the smart key cannot be quickly located and found in the car or even lost in the car. To this end, the present application proposes a smart key positioning scheme based on a configurable atmosphere light, and its inventive concept is: the vehicle controller controls multiple first low-frequency antennas in the car to turn on based on the key positioning request generated by the user's first touch operation, and controls a second low-frequency antenna in the car to turn on at the same time, so that the smart key dropped in the car can receive the low-frequency signals sent by the multiple low-frequency antennas, and the smart key decides and turns on the buzzer set on the smart key based on the received multiple first low-frequency signals and / or second low-frequency signals, and the buzzer is used to prompt the user to locate and find the smart key through buzzing. Therefore, the buzzing prompt of the buzzer can assist the user to quickly, conveniently and accurately locate and find the smart key, thereby improving the user experience.

[0053] Reference Figure 1 , which is a schematic diagram of the steps of a smart key positioning method provided in an embodiment of the present application.

[0054] like Figure 1 As shown, the positioning method of the smart key may include the following steps:

[0055] Step 102: The vehicle controller generates a key location request in response to a first touch operation of the user.

[0056] When the user needs to locate and find the smart key, he can perform a first touch operation such as clicking, double-clicking, or pressing a physical button or a virtual button on the central control screen, whereby the vehicle controller generates a key location request in response to the first touch operation.

[0057] In the present application, the key location request may be a transmission signal within the vehicle control system, such as a request signal instruction transmitted via a CAN bus.

[0058] It should be understood that in the present application, the vehicle controller can be regarded as a control device that integrates multiple control modules such as a central control screen, a keyless start module, and a body control module. In an actual positioning scheme, different modules can be used to collaboratively implement the corresponding different functions of the vehicle controller.

[0059] Step 104: Based on the key positioning request, the vehicle controller controls a plurality of first low-frequency antennas arranged in different areas of the vehicle to be turned on, and at the same time, controls a second low-frequency antenna arranged in the middle position of the vehicle to be turned on.

[0060] In different areas inside the vehicle, multiple first low-frequency antennas are dispersedly arranged, and at the same time, a second low-frequency antenna is set in the middle position of the vehicle. After the vehicle controller generates a key positioning request, it can control the opening of multiple first low-frequency antennas in the vehicle based on the key positioning request, so that multiple first low-frequency antennas send first low-frequency signals, and the frequencies of these first low-frequency signals are the same. In order to facilitate distinction, the signal identifiers of each first low-frequency signal are different. At the same time, the vehicle controller also controls the opening of the second low-frequency antenna in the middle position of the vehicle according to the key positioning request. For example, a total of 8 first low-frequency antennas are respectively set in 8 different areas in the vehicle, first low-frequency antenna 1, first low-frequency antenna 2, first low-frequency antenna 3...first low-frequency antenna 6, first low-frequency antenna 7 and first low-frequency antenna 8; each first low-frequency antenna will send its own first low-frequency signal, and each first low-frequency signal uses the identifier of the first low-frequency antenna as a signal identifier, such as first low-frequency signal 1, first low-frequency signal 2, first low-frequency signal 3...first low-frequency signal 6, first low-frequency signal 7 and first low-frequency signal 8.

[0061] Step 106: The multiple first low-frequency antennas respectively send first low-frequency signals of the same frequency, and the second low-frequency antenna sends a second low-frequency signal; wherein the second low-frequency signal carries an antenna identifier for triggering the smart key opening buzzer.

[0062] The second low-frequency antenna is similar in type to the first low-frequency antenna, and the low-frequency signal it sends has the same frequency. The difference is that the second low-frequency signal sent by the second low-frequency antenna carries an antenna identifier for triggering the smart key to turn on the buzzer. In other words, the second low-frequency signal has the function of triggering the smart key to turn on the buzzer, and can be triggered based on the antenna identifier it carries. In fact, it can also be triggered by other message content it carries. This application does not make any limitation, as long as the message content can trigger the buzzer to turn on.

[0063] Step 108: The smart key decides and turns on a buzzer provided on the smart key based on the received multiple first low-frequency signals and / or second low-frequency signals, and the buzzer is used to prompt the user to locate and find the smart key through buzzing.

[0064] Optionally, the smart key makes a decision and turns on the buzzer based on the received multiple first low-frequency signals and / or second low-frequency signals. Specifically, it can be determined whether the number of received first low-frequency signals exceeds a threshold and whether the second low-frequency signal is received; if it is determined that the number of received first low-frequency signals exceeds the threshold and the second low-frequency signal is received, the buzzer is turned on; otherwise, after turning off the signal receiving switch of the smart key for a preset period of time, it is turned on again and multiple first low-frequency signals and / or second low-frequency signals are received until it is determined that the number of received first low-frequency signals exceeds the threshold and the second low-frequency signal is received.

[0065] Considering that the second low-frequency signal is set in the middle position of the car, therefore, when the signal strength can be guaranteed, the second low-frequency signal it sends can almost evenly cover the entire car. Therefore, after receiving multiple first low-frequency signals, the smart key needs to determine whether the number of received first low-frequency signals reaches the threshold. Only when a sufficient number of first low-frequency signals are received can it be ensured that the smart key is dropped in the car and the first low-frequency antennas are effectively turned on. Furthermore, it is also necessary to determine whether the smart key receives the second low-frequency signal at the same time to further ensure that the second low-frequency antenna is effectively turned on. Only when these two conditions are met at the same time can the buzzer on the smart key be triggered to turn on. If only one of these two conditions is not met, it is necessary to repeatedly disconnect the signal receiving switch of the smart key, reopen and receive multiple first low-frequency signals and / or second low-frequency signals, until it is determined that the number of received first low-frequency signals exceeds the threshold and the second low-frequency signal is received, then the buzzer is triggered to turn on. In fact, after repeatedly disconnecting the signal receiving switch of the smart key, the first low-frequency antenna and the second low-frequency antenna in the car can be repeatedly turned on by turning off and restarting the button on the central control screen, until the number of first low-frequency signals received by the smart key exceeds the threshold and the second low-frequency signal is received. In this way, the validity of the low-frequency signal received by the smart key is guaranteed, and the smart key is in the car, improving the positioning accuracy. If the signal interface switch of the smart key is repeatedly disconnected, it is still impossible to ensure that the number of first low-frequency signals received exceeds the threshold and the second low-frequency signal is received, it can be determined that the smart key is not in the car and cannot trigger the buzzer to turn on.

[0066] Furthermore, in the present application, each first low-frequency signal carries a location identifier for characterizing the location of the first low-frequency antenna that sends the first low-frequency signal; when the user locates and searches for the smart key based on the buzzer prompt, the smart key can also convert the multiple first low-frequency signals into a high-frequency signal and send it to the vehicle controller; the vehicle controller parses the multiple first low-frequency signals based on the received high-frequency signals, and locates the smart key based on the location identifier carried by the first low-frequency signal with the largest field strength; the vehicle controller controls the corresponding light strip control areas of the atmosphere light to light up according to the positioning result, so as to assist the buzzer in prompting the user of the location area of ​​the smart key in the vehicle.

[0067] It should be noted that when the user is prompted to locate and search for the smart key in combination with the ambient light on the basis of the buzzer prompt, the high-frequency antenna in the car can be further turned off based on the key positioning request in step 104. The high-frequency antenna in the car here can be other antenna devices in the car that can transmit high-frequency signals, for example, a wireless charging device in the car, which can release high-frequency signals when wirelessly charging electronic products such as mobile phones. Since the subsequent steps require the vehicle controller to receive the high-frequency signal returned by the smart key for analysis and other processing, in order to avoid confusion with the high-frequency signal returned by the smart key, it is necessary to control the high-frequency antenna in the car to be turned off while the vehicle controller controls the low-frequency antenna to be turned on, so that it can be ensured that the received signal is the high-frequency signal converted from multiple low-frequency signals returned by the smart key, thereby improving processing efficiency.

[0068] The smart key of the present application may be a remote control key with functions such as remote locking and unlocking of the vehicle and wireless starting of the vehicle.

[0069] The smart key is also provided with a signal transmitter; after the first low-frequency antenna in the car is turned on and sends the first low-frequency signal, the smart key receives the first low-frequency signal from different positions through the signal receiver. Each of these first low-frequency signals carries a position identifier for representing the position of the first low-frequency antenna that sends the first low-frequency signal. That is, each first low-frequency signal includes a signal identifier representing the first low-frequency antenna identifier and a position identifier of the first low-frequency antenna position in addition to the signal identifier representing the first low-frequency antenna identifier. For example, the first low-frequency signal 1-front left door, the first low-frequency signal 2-front right door, the first low-frequency signal 3-rear left door, the first low-frequency signal 4-rear right door, the first low-frequency signal 5-middle of the front seat, the first low-frequency signal 6-middle of the rear seat, the first low-frequency signal 7-below the central control, and the first low-frequency signal 8-trunk. It should be understood that this is only for the convenience of understanding the example statement, and the actual setting position and position identifier of the first low-frequency antenna can be flexibly set and adjusted according to the vehicle design, and it is not limited to this.

[0070] After receiving multiple first low-frequency signals, the smart key converts these first low-frequency signals into a high-frequency signal and sends it to the vehicle controller. Specifically, these first low-frequency signals can be converted into a high-frequency signal through a conversion module such as an amplifier circuit or a frequency converter. This application is not limited to this, and any feasible conversion scheme can be used to implement it.

[0071] In the present application, when converting multiple low-frequency signals into a high-frequency signal, the low-frequency signal can be converted into a high-frequency signal by a microprocessor unit, and the high-frequency signal is presented in the form of a message. Among them, different message segments in the message content of the high-frequency signal record different low-frequency signals, that is, each message segment records a low-frequency signal information, for example, the signal identification of the low-frequency signal, the field strength, etc. In this way, the signal content of multiple low-frequency signals can be fully covered by a high-frequency signal, reducing the delay and error rate of the transmission of multiple low-frequency signals.

[0072] Optionally, in the present application, when the vehicle controller controls the corresponding light strip control area of ​​the atmosphere light to be differentiated and lit according to the positioning result, the atmosphere light can be turned on according to the positioning result, and the atmosphere light can be switched to the positioning key mode; in the positioning key mode, the corresponding light strip control area can be controlled to be differentiated and lit. Specifically, after the vehicle controller determines the location identifier carried by the low-frequency signal with the largest field strength, it can turn on the vehicle's atmosphere light according to the positioning result, and switch the atmosphere light from the normal control mode to the positioning key mode, so as to avoid the atmosphere light affecting the positioning of the smart key in the normal lighting mode. When the atmosphere light is switched to the positioning key mode, the corresponding light strip control area can be controlled to be differentiated and lit to prompt the user of the location area of ​​the smart key in the vehicle, and the beeping of the auxiliary buzzer prompts the user to quickly and accurately locate and find the smart key.

[0073] Further, in the present application, after the vehicle controller switches the ambient light to the positioning key mode, according to the positioning result, that is, the position corresponding to the position identifier carried by the low-frequency signal with the largest field strength, the ambient light is divided into a main light strip control area close to the position area where the low-frequency antenna corresponding to the position identifier is located, and a secondary light strip control area away from the position area; the main light strip control area and the secondary light strip control area are controlled to be illuminated separately. Specifically, refer to Figure 2a The figure shows the schematic diagram of the low-frequency antenna distribution and the ambient light distribution in the vehicle provided by the embodiment of the present application. Figure 2a In the example, 8 low-frequency antennas are still used, which are distributed in different areas in the vehicle, such as low-frequency antenna 1 to low-frequency antenna 8. When the vehicle controller analyzes the high-frequency signal and finds that the low-frequency signal with the largest field strength is emitted by low-frequency antenna 3, it analyzes the location of the low-frequency signal 3 as [rear left door] from the location identifier carried by the low-frequency signal 3. Based on the positioning result, the ambient light close to the rear door can be divided into the main light control area. The proximity here can be set to a specific distance. For example, the ambient light units within the threshold distance from the center point of the rear door are defined as the main light control area. Figure 2aAs shown, the ambient light unit on the rear left door and part of the ambient light unit located behind the front left seat are divided into the main light control area, that is, the ambient light area circled by the dotted circle; and the rest of the ambient light is the auxiliary light control area.

[0074] Furthermore, the main light strip control area and the auxiliary light strip control area can be controlled to light up separately. Specifically, the main light strip control area can be controlled to light up a first color, and the auxiliary light strip control area can be controlled to light up a second color, the first color is different from the second color; and / or; the main light strip control area can be controlled to flash after lighting up, and the auxiliary light strip control area can be controlled not to flash after lighting up. Figure 2b As shown, it is a schematic diagram of different light strip control areas of the atmosphere light provided in the embodiment of the present application being illuminated separately. In the scheme of the present application, the lighting of the atmosphere light is not only for illumination, but also to prompt the user of the location area of ​​the smart key through different lighting effects. Therefore, when controlling different light strip control areas for differentiated lighting, the main light strip control area can be controlled to light up in a more eye-catching red, and the auxiliary light strip control area, that is, the rest of the atmosphere light, can be controlled to light up in yellow. Here, red and yellow are taken as examples, and other color combinations can also be used, which are not listed here one by one. In fact, in addition to distinguishing by the color of lighting, the main light strip control area can also be controlled to flash after lighting up, and the auxiliary light strip control area can be controlled not to flash after lighting up, that is, to distinguish by the rhythmic mode after lighting up. In addition, different rhythmic modes can be superimposed on the basis of lighting up different colors, that is, the lighting color and the rhythmic mode are superimposed to achieve differentiated lighting. Whether distinguishing by different colors, different rhythms, or by the dual superposition of different colors and different rhythms, the lighting effects can be clearly distinguished, providing effective prompts for users to locate and find the keys, narrowing the search range, and thus, combined with the beeping sound prompts, it is convenient to quickly and accurately locate and find the smart key, thereby improving the user experience.

[0075] Optionally, after the user locates the smart key based on the buzzer prompt, the vehicle controller responds to the user's second touch operation to turn off multiple first low-frequency antennas and the second low-frequency antenna in the vehicle.

[0076] The second touch operation here can correspond to the user's first touch operation. The operation types of the two are similar, and both can be touch operations such as pressing, clicking or rotating the physical or virtual buttons on the central control screen. The difference is the generated command content. The command generated in response to the second touch operation is used to turn off multiple first low-frequency antennas and second low-frequency antennas in the car to avoid wasting power in the car. At the same time, in order to ensure the normal use of the car's functions, such as the in-car wireless charging device, the high-frequency antenna in the car can be turned on in time.

[0077] Reference Figure 3, which is a schematic diagram of the steps of locating a smart key provided in another embodiment of the present application.

[0078] Step 302: The vehicle controller generates a key location request in response to a first touch operation of the user.

[0079] Step 304: The vehicle controller controls multiple first low-frequency antennas and one second low-frequency antenna arranged in different areas of the vehicle to turn on based on the key positioning request, and at the same time, turns off the high-frequency antenna in the vehicle based on the key positioning request.

[0080] Step 306: The smart key determines whether the number of received first low-frequency signals exceeds a threshold and whether a second low-frequency signal is received. If yes, step 308 is executed; otherwise, step 310 is executed.

[0081] Step 308: The smart key turns on the buzzer.

[0082] Step 310: After turning off the signal receiving switch of the smart key for a preset period of time, reopen it and receive multiple first low frequency signals and / or second low frequency signals until it is determined that the number of received first low frequency signals exceeds a threshold and a second low frequency signal is received, then jump to step 308.

[0083] Step 312: while the buzzer is turned on, the key smart key converts a plurality of first low-frequency signals into a high-frequency signal and sends it to the vehicle controller.

[0084] Step 314: The vehicle controller parses a plurality of first low-frequency signals according to the received high-frequency signal, and locates the smart key based on the position identifier carried by the first low-frequency signal with the largest field strength.

[0085] Step 316: The vehicle controller turns on the ambient light according to the positioning result, and switches the ambient light to the positioning key mode.

[0086] Step 318: In the positioning key mode, the vehicle controller divides the ambient light into a main light strip control area close to the location area of ​​the first low-frequency antenna corresponding to the location identifier, and a secondary light strip control area away from the location area according to the positioning result.

[0087] Step 320: Control the main light strip control area to light up a first color, and control the auxiliary light strip control area to light up a second color, wherein the first color is different from the second color, so as to assist the buzzer in reminding the user of the location of the smart key in the vehicle.

[0088] Step 322: After the user finds the smart key based on the prompts of the ambient light and the buzzer, the vehicle controller responds to the user's second touch operation, turns off the ambient light and the first low-frequency antenna and the second low-frequency antenna, and turns on the high-frequency antenna in the vehicle.

[0089] Through this technical solution, the sound prompts of the smart key buzzer and the lighting prompts of the ambient light can help users quickly, conveniently and accurately locate the smart key, thereby improving the user experience.

The plurality of first low-frequency antennas 403 respectively send first low-frequency signals of the same frequency, and the second low-frequency antenna 404 sends a second low-frequency signal; wherein, the second low-frequency signal carries an antenna identifier for triggering the smart key 402 to turn on the buzzer 405. The smart key 402 decides and turns on a buzzer 405 disposed on the smart key 402 based on the received multiple first low-frequency signals and / or second low-frequency signals, so as to prompt the user to locate and find the smart key 402 through the buzzer. Figure 4 The buzzer 405 is disposed inside the smart key 402 , and therefore is not shown and is only referred to as the smart key.

[0093] Optionally, in a possible implementation of the present embodiment, when the smart key 402 makes a decision and turns on the buzzer based on the received multiple first low-frequency signals and / or second low-frequency signals, it is specifically used to determine whether the number of received first low-frequency signals exceeds a threshold and whether a second low-frequency signal is received; if it is determined that the number of received first low-frequency signals exceeds the threshold and the second low-frequency signal is received, the buzzer is turned on; otherwise, after turning off the signal receiving switch of the smart key for a preset period of time, it is reopened and multiple first low-frequency signals and / or second low-frequency signals are received until it is determined that the number of received first low-frequency signals exceeds the threshold and the second low-frequency signal is received.

[0094] Optionally, in a possible implementation of the present embodiment, each first low-frequency signal carries a location identifier for characterizing the location of the first low-frequency antenna that sends the first low-frequency signal; when the user locates and searches for the smart key based on the buzzer prompt, the smart key 402 is also used to convert the multiple first low-frequency signals into a high-frequency signal and send it to the vehicle controller; the vehicle controller 401 parses multiple first low-frequency signals based on the received high-frequency signals, and locates the smart key based on the location identifier carried by the first low-frequency signal with the largest field strength; and based on the positioning result, controls the corresponding light strip control areas of the atmosphere light to be differentiated and lit, so as to assist the buzzer 405 in prompting the user of the location area of ​​the smart key 402 in the vehicle.

[0095] Optionally, in a possible implementation of this embodiment, when the vehicle controller 401 controls the corresponding light strip control areas of the atmosphere light to be differentiated and lit up according to the positioning result, it is specifically used to turn on the atmosphere light according to the positioning result and switch the atmosphere light to the positioning key mode; in the positioning key mode, the atmosphere light is divided into a main light strip control area close to the position area of ​​the smart key in the vehicle, and a secondary light strip control area far from the position area according to the positioning result; the main light strip control area and the secondary light strip control area are controlled to be differentiated and lit up.

[0096] Optionally, in a possible implementation of this embodiment, after the user locates the smart key based on the beep prompt, the vehicle controller 401 is also used to respond to the user's second touch operation to turn off multiple first low-frequency antennas 403 and the second low-frequency antenna 404 in the vehicle.

[0097] In this embodiment, the vehicle controller can control the opening of multiple first low-frequency antennas in the vehicle based on the key positioning request generated by the user's first touch operation, and control the opening of a second low-frequency antenna in the vehicle at the same time, so that the smart key dropped in the vehicle can receive the low-frequency signals sent by the multiple low-frequency antennas, and the smart key makes a decision and turns on the buzzer set on the smart key based on the received multiple first low-frequency signals and / or second low-frequency signals, and the buzzer is used to prompt the user to locate and find the smart key through the buzzer. Therefore, the buzzer prompt can help the user to quickly, conveniently and accurately locate and find the smart key, thereby improving the user experience.
