[0047] 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.

[0048] 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.

[0049] 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.

[0050] 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.

[0051] 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 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 low-frequency antennas in the car to turn on based on the key positioning request generated by the user's first touch operation, and at the same time turns off the high-frequency antenna that affects the judgment of the high-frequency signal, so that the smart key dropped in the car can receive multiple low-frequency signals sent by multiple low-frequency antennas, and convert these low-frequency signals into a high-frequency signal and send it to the vehicle controller, after which the vehicle controller can parse the high-frequency signal, analyze and find the low-frequency signal with the largest field strength, and based on the position identifier carried by the low-frequency signal, control the light strip control area corresponding to the position of the position identifier in the atmosphere light to light up, and distinguish it from other areas, so that the user can be prompted to the location area of ​​the smart key in the car by clearly distinguishing and lighting up, and on the premise of providing the user with necessary lighting, assist the user to quickly, conveniently and accurately locate the smart key, and improve the user experience.

[0052] Reference Figure 1 , which is a schematic diagram of the steps of a method for locating a smart key based on a configurable ambient light provided in an embodiment of the present application.

[0053] like Figure 1 As shown, the method for locating a smart key based on a configurable ambient light may include the following steps:

[0054] Step 102: The vehicle controller generates a key location request in response to a first touch operation of the user.

[0055] 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.

[0056] 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.

[0057] 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.

[0058] Step 104: The vehicle controller controls multiple low-frequency antennas arranged in different areas of the vehicle to turn on based on the key positioning request, so that the multiple low-frequency antennas respectively send low-frequency signals of the same frequency; at the same time, the high-frequency antenna in the vehicle is turned off based on the key positioning request.

[0059] Multiple low-frequency antennas are arranged in different areas inside the vehicle. After the vehicle controller generates a key positioning request, it can control the opening of multiple low-frequency antennas in the vehicle based on the key positioning request, so that multiple low-frequency antennas send low-frequency signals. The frequencies of these low-frequency signals are the same. In order to facilitate distinction, the signal identifier of each low-frequency signal is different. For example, a total of 8 low-frequency antennas are respectively arranged in 8 different areas in the vehicle, low-frequency antenna 1, low-frequency antenna 2, low-frequency antenna 3... low-frequency antenna 6, low-frequency antenna 7 and low-frequency antenna 8; each low-frequency antenna will send out its own low-frequency signal, and each low-frequency signal uses the identifier of the low-frequency antenna as a signal identifier, such as low-frequency signal 1, low-frequency signal 2, low-frequency signal 3... low-frequency signal 6, low-frequency signal 7 and low-frequency signal 8.

[0060] At the same time, the vehicle controller also controls the high-frequency antenna in the car to turn off according to the key positioning request. The high-frequency antenna in the car here can be other antenna devices in the car that can transmit high-frequency signals. For example, the wireless charging device in the car can release high-frequency signals when wirelessly charging mobile phones and other electronic products. 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 turn off while the vehicle controller controls the low-frequency antenna to turn on. In this way, 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.

[0061] Step 106: The smart key receives multiple low-frequency signals, converts the multiple low-frequency signals into a high-frequency signal and sends it to the vehicle controller; wherein each low-frequency signal carries a location identifier for representing the location of the low-frequency antenna that sends the low-frequency signal.

[0062] 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.

[0063] The smart key is provided with a signal receiver and a signal transmitter; after the low-frequency antennas in the vehicle are turned on and send low-frequency signals respectively, the smart key receives low-frequency signals from different positions through the signal receiver. Each of these low-frequency signals carries a position identifier for representing the position of the low-frequency antenna that sends the low-frequency signal. That is, each low-frequency signal contains not only a signal identifier representing the low-frequency antenna identifier, but also a position identifier of the low-frequency antenna position. For example, low-frequency signal 1-front left door, low-frequency signal 2-front right door, low-frequency signal 3-rear left door, low-frequency signal 4-rear right door, low-frequency signal 5-middle of the front seat, low-frequency signal 6-middle of the rear seat, low-frequency signal 7-below the central control, 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 low-frequency antenna can be flexibly set and adjusted according to the vehicle design, and it is not limited to this.

[0064] After receiving multiple low-frequency signals, the smart key converts these low-frequency signals into a high-frequency signal and sends it to the vehicle controller. Specifically, these low-frequency signals can be converted into a high-frequency signal through an amplifier circuit or a conversion module such as a frequency converter. This application is not limited to this, and any feasible conversion scheme can be used to implement it.

[0065] In the present application, when converting multiple low-frequency signals into a high-frequency signal, the low-frequency signals 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.

[0066] Step 108: The vehicle controller parses a plurality of low-frequency signals according to the received high-frequency signal, and locates the smart key based on the position identifier carried by the low-frequency signal with the largest field strength.

[0067] After the vehicle controller receives the high-frequency signal, it can parse the high-frequency signal and restore multiple low-frequency signals. Since the low-frequency antennas that emit these low-frequency signals are distributed in different positions in the vehicle, the field strength of each low-frequency signal received by the smart key is also different: the low-frequency signal emitted by the low-frequency antenna that is closer to the smart key has a larger field strength; the low-frequency signal emitted by the low-frequency antenna that is farther away has a smaller field strength received by the smart key. In this way, the field strength carried by these low-frequency signals can be analyzed to determine that the low-frequency antenna corresponding to the low-frequency signal with the largest field strength is closest to the smart key. Therefore, the smart key can be located according to the position identifier carried by the low-frequency signal with the largest field strength.

[0068] Step 110: The vehicle controller controls the corresponding light strip control area of ​​the ambient light to light up according to the positioning result, so as to prompt the user of the location area of ​​the smart key in the vehicle.

[0069] Afterwards, the vehicle controller determines the location identifier carried by the low-frequency signal with the largest field strength as the positioning result of this time, and controls the corresponding light strip control area determined based on the position corresponding to the location identifier in the ambient light to be distinguished and lit up, and distinguished from other corresponding light strip control areas through different lighting effects to prompt the user of the location area of ​​the smart key in the car, helping the user to quickly and accurately locate and find the smart key.

[0070] Optionally, in the present application, when the vehicle controller controls the corresponding light strip control areas of the ambient light to be differentiated and lit up according to the positioning results, it can specifically turn on the ambient light according to the positioning results and switch the ambient light to the positioning key mode; in the positioning key mode, the corresponding light strip control areas are controlled to be differentiated and lit up.

[0071] 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 ambient light according to the positioning result, and switch the ambient light from the normal control mode to the positioning key mode, so as to avoid the ambient light affecting the positioning of the smart key in the normal lighting mode. When the ambient light is switched to the positioning key mode, the corresponding light strip control area can be controlled to light up separately to prompt the user the location area of ​​the smart key in the car, and assist the user to quickly and accurately locate and find the smart key.

[0072] 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 2a As 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.

[0073] 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 it is distinguished by different colors, different rhythms, or by the dual superposition of different colors and different rhythms, the lighting effect can be clearly distinguished, providing effective prompts for users to locate and find keys, narrowing the search range, facilitating quick and accurate positioning of smart keys, and improving user experience.

[0074] Optionally, after the user finds the smart key based on the prompt of the ambient light, the vehicle controller responds to the user's second touch operation, turns off the ambient light, and turns on the high-frequency antenna in the vehicle.

[0075] 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 content of the generated instructions. The instructions generated in response to the second touch operation are used to turn off the atmosphere lights and turn on the high-frequency antenna in the car. Considering that the atmosphere lights are turned on to prompt and assist users to find the smart key, then after finding the smart key, in order to avoid wasting power in the car, the atmosphere lights can be turned off as soon as possible. In order to ensure the use of normal functions in the car, such as the wireless charging device in the car, the high-frequency antenna in the car can be turned on in time.

[0076] Reference Figure 3 , which is a schematic diagram of the steps for locating a smart key based on a configurable ambient light provided in another embodiment of the present application.

[0077] Step 302: The vehicle controller generates a key location request in response to a first touch operation of the user.

[0078] Step 304: The vehicle controller controls multiple low-frequency antennas arranged in different areas in 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.

[0079] Step 306: The smart key receives a plurality of low-frequency signals, converts the plurality of low-frequency signals into a high-frequency signal and sends it to the vehicle controller.

[0080] Step 308: The vehicle controller parses multiple low-frequency signals according to the received high-frequency signal, and locates the smart key based on the position identifier carried by the low-frequency signal with the largest field strength.

[0081] Step 310: The vehicle controller turns on the ambient light according to the positioning result, and switches the ambient light to the positioning key mode.

[0082] Step 312: 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 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.

[0083] Step 314: 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 remind the user of the location of the smart key in the vehicle.

[0084] Step 316: After the user finds the smart key based on the prompt of the ambient light, the vehicle controller responds to the user's second touch operation, turns off the ambient light, and turns on the high-frequency antenna in the vehicle.

[0085] Through this technical solution, multiple low-frequency signals can be obtained based on the analysis of the high-frequency signal returned by the smart key to the vehicle controller, and the low-frequency antenna closest to the smart key can be determined based on the field strength of the low-frequency signal. The ambient light can be divided into a main light control area and a secondary light strip control area according to the location of the low-frequency antenna, and then the main light control area and the secondary light strip control area can be controlled to light up different colors. By distinguishing the lighting effects, the user can be prompted to the approximate location area of ​​the smart key in the car. On the premise of providing the user with necessary lighting, the user can be assisted to quickly, conveniently and accurately locate the smart key, thereby improving the user experience.

The smart key 402 receives multiple low-frequency signals, and converts the multiple low-frequency signals into a high-frequency signal and sends it to the vehicle controller 401; wherein each low-frequency signal carries a location identifier for representing the location of the low-frequency antenna that sends the low-frequency signal. The vehicle controller 401 parses multiple low-frequency signals based on the received high-frequency signal, and locates the smart key 402 based on the location identifier carried by the low-frequency signal with the largest field strength. The vehicle controller 402 controls the corresponding light strip control area of ​​the atmosphere light 404 to light up according to the positioning result, so as to remind the user of the location area of ​​the smart key 402 in the vehicle.
