[0052] Please refer to Figure 1 , which shows a flow chart of a method for locating a remote control key provided by an embodiment of the present application. The method for locating a remote control key may specifically include:

[0053] Step 101: Obtain positioning request information of a remote control key.

[0054] Step 102: based on the positioning request information of the remote control key, obtain the signal values ​​and field strength values ​​of multiple low-frequency antennas; the signal values ​​and field strength values ​​of the multiple low-frequency antennas are collected from the remote control key by using the keyless entry and start PEPS module.

[0055] Step 103: Based on the signal values ​​and field strength values ​​of the multiple low-frequency antennas, positioning processing is performed on the remote control key to obtain the position information of the remote control key.

[0056] Step 104: Based on a preset first distance condition, the position information of the remote control key is matched with the position information of at least one in-vehicle speaker to determine a first in-vehicle speaker that matches the remote control key.

[0057] Step 105: Control the first in-vehicle speaker to output a positioning prompt tone of the remote control key.

[0058] It should be noted that the remote control key may be a smart key for controlling the vehicle. The remote control key may control the vehicle to power on through the PEPS module.

[0059] It should be noted that the position information of the remote control key may include coordinate information of the remote control key. For example, the coordinate information may be (x, y) in the vehicle coordinate system.

[0060] It should be noted that the signal values ​​and field strength values ​​of the multiple low-frequency antennas may be low-frequency signal values ​​and field strength values ​​corresponding to the low-frequency signal values.

[0061] In this way, by acquiring the positioning request information of the remote control key, the signal values ​​and field strength values ​​of multiple low-frequency antennas can be obtained based on the positioning request information of the remote control key; the signal values ​​and field strength values ​​of the multiple low-frequency antennas are collected from the remote control key by using the PEPS module, and the remote control key is positioned based on the signal values ​​and field strength values ​​of the multiple low-frequency antennas to obtain the position information of the remote control key, and based on a preset first distance condition, the position information of the remote control key is matched with the position information of at least one in-vehicle speaker to determine a first in-vehicle speaker that matches the remote control key, and the first in-vehicle speaker is controlled to output a positioning prompt sound of the remote control key. Since the remote control key in the car can be intuitively positioned by combining the prompt sound of the speaker of the car audio system, the accuracy of positioning the remote control key in the car can be improved, which can help the driver quickly find the key, thereby optimizing the user experience.

[0062] Optionally, in a possible implementation of this embodiment, in step 101, in response to the driver's triggering operation of the key search control of the central control module, a key search mode is started, and then based on the key search mode, the positioning request information of the remote control key can be obtained.

[0063] In this implementation, the central control interface of the vehicle's central control module can output and display a key finder control so that the driver can trigger the key finder control when he needs to find the key and control the vehicle to enter a key finder mode.

[0064] Here, the trigger operation may include but is not limited to a click operation, a slide operation, and a gesture operation.

[0065] In this way, the flexibility and convenience of the driver starting the key search can be improved through the interactive method of the central control interface of the vehicle's central control module.

[0066] Optionally, in a possible implementation of this embodiment, in step 103, first, the position information of each low-frequency antenna can be obtained based on the signal values ​​of the multiple low-frequency antennas. Secondly, the position information of the remote control key can be calculated based on the position information and field strength value of each low-frequency antenna using a preset positioning algorithm.

[0067] In this implementation, the signal value of the low-frequency antenna may include a signal identifier and location information.

[0068] In this implementation, the preset positioning algorithm may be a triangulation positioning algorithm or a multi-point positioning algorithm.

[0069] In a specific implementation process of this implementation method, based on the signal identification, position information and field strength value of each low-frequency antenna, the position information of the low-frequency antenna with the largest field strength value is determined, and then based on the position information of the low-frequency antenna with the largest field strength value, the position information of the remote control key can be calculated using a preset positioning algorithm.

[0070] In this way, more accurate remote control key location information can be obtained by using a preset positioning algorithm based on the location information and field strength value of each low-frequency antenna, thereby further improving the accuracy of remote control key positioning.

[0071] It should be noted that the specific implementation process provided in this implementation can be combined with the various specific implementation processes provided in the aforementioned implementation to implement the remote control key positioning method of this embodiment. For detailed description, please refer to the relevant content in the aforementioned implementation, which will not be repeated here.

[0072] Optionally, in a possible implementation of this embodiment, in step 104, first, the position information of at least one in-car speaker is obtained. Secondly, based on the position information of the remote control key and the position information of each in-car speaker, the distance between the remote control key and each in-car speaker can be calculated respectively. Thirdly, based on the preset first distance condition and the distance between the remote control key and each in-car speaker, the remote control key and each in-car speaker are matched. Thirdly, the in-car speaker whose result of the matching process is that the distance between the remote control key and the in-car speaker meets the preset first distance condition is used as the first in-car speaker.

[0073] In this implementation, the preset first distance condition can be that the distance between the remote control key and the in-car speaker is the minimum value of the distance between the remote control key and each in-car speaker, that is, the distance between the in-car speaker and the remote control key is the minimum value of the distance between all in-car speakers and the remote control key.

[0074] Here, the first in-vehicle speaker may be the in-vehicle speaker closest to the remote control key.

[0075] In this way, the in-vehicle speaker closest to the remote control key can be accurately determined by utilizing the preset first distance condition.

[0076] It should be noted that the specific implementation process provided in this implementation can be combined with the various specific implementation processes provided in the aforementioned implementation to implement the remote control key positioning method of this embodiment. For detailed description, please refer to the relevant content in the aforementioned implementation, which will not be repeated here.

[0077] Optionally, in a possible implementation of this embodiment, the positioning prompt sound of the remote control key may include a buzzer, a beep, a voice prompt sound, etc.

[0078] Optionally, in a possible implementation of the present embodiment, after step 103, further, the location information of at least one in-vehicle lighting device can be obtained, and then based on a preset second distance condition, the location information of the remote control key can be matched with the location information of each in-vehicle lighting device respectively to determine the first in-vehicle lighting device that matches the remote control key, and control the first in-vehicle lighting device to output the positioning prompt light of the remote control key.

[0079] In this implementation, the preset second distance condition can be that the distance between the remote control key and the lighting device is the minimum value of the distance between the remote control key and each lighting device, that is, the distance between the lighting device and the remote control key is the minimum value of the distance between all lighting devices and the remote control key.

[0080] It can be understood that the first in-vehicle lighting device may be the lighting device that is closest to the remote control key among all the lighting devices.

[0081] In a specific implementation process of this implementation mode, first, the distance between the remote control key and each in-vehicle lighting device can be calculated based on the location information of the remote control key and the location information of each in-vehicle lighting device. Secondly, the remote control key and each in-vehicle lighting device can be matched based on the preset second distance condition and the distance between the remote control key and each in-vehicle lighting device. Thirdly, the in-vehicle speaker whose matching result is that the distance between the remote control key and the in-vehicle lighting device meets the preset second distance condition is used as the first in-vehicle lighting device.

[0082] Here, when the distance between the remote control key and any one of the in-vehicle lighting devices meets a preset second distance condition, the any one of the in-vehicle speakers can be used as the first in-vehicle lighting device.

[0083] In this implementation, the in-vehicle lighting equipment may include in-vehicle lighting lamps and atmosphere lights, etc.

[0084] In this implementation, the positioning prompt light may include a lighting light of a preset light color and / or an atmosphere light. The preset light color may include any one of green, red, and orange.

[0085] In another specific implementation process of this implementation method, the first in-vehicle lighting lamp is controlled to output the positioning prompt light of the remote control key according to a preset light color, or the first in-vehicle atmosphere lamp is controlled to output the positioning prompt light of the remote control key according to a preset light color.

[0086] In this way, the in-vehicle lighting device closest to the remote control key can be determined to better help the driver find the remote control key, thereby improving the driver's user experience.

[0087] It should be noted that the specific implementation process provided in this implementation can be combined with the various specific implementation processes provided in the aforementioned implementation to implement the remote control key positioning method of this embodiment. For detailed description, please refer to the relevant content in the aforementioned implementation, which will not be repeated here.

[0088] Figure 2 FIG. 1 is a schematic diagram of the architecture of a remote control key positioning system provided by another embodiment of the present application. Figure 2 In this embodiment, the remote control key positioning system may include a vehicle control module, a central control module, a PEPS module, a plurality of low-frequency antennas, and at least one speaker.

[0089] In this embodiment, Figure 2 As shown, the vehicle control module can be used to execute the remote control key positioning method in the aforementioned embodiment. The PEPS module can be used to send the remote control key scanning instruction to the multiple low-frequency antennas based on the received remote control key positioning request information, and collect high-frequency signal values ​​and field strength values ​​of the multiple low-frequency antennas from the remote control key. The multiple low-frequency antennas can be used to scan the remote control key based on the remote control key scanning instruction, so that the remote control key generates high-frequency signal values ​​and field strength values ​​of multiple low-frequency antennas. The at least one speaker can be used to output the positioning prompt tone of the remote control key in response to the control of the vehicle control module.

[0090] Optionally, in a possible implementation of this embodiment, the remote control key positioning system may further include a central control module. The central control module may be configured to start a key search mode in response to a driver's triggering operation of a key search control of the central control module, so as to obtain the remote control key positioning request information based on the key search mode.

[0091] Optionally, in a possible implementation of this embodiment, the multiple low-frequency antennas can be used to scan and process the remote control key based on the remote control key scanning instruction, and send low-frequency signal data to the remote control key, so that the remote control key generates high-frequency signal values ​​and field strength values ​​of multiple low-frequency antennas based on the received low-frequency signal data.

[0092] Here, the remote control key converts the low-frequency signal data received from each low-frequency antenna to obtain corresponding high-frequency signal data, namely the high-frequency signal values ​​and field strength values ​​of multiple low-frequency antennas, and sends the high-frequency signal data to the high-frequency receiver of the PEPS module.

[0093] Optionally, in a possible implementation of this embodiment, the remote control key positioning system may further include a lighting device. The central control module may be configured to output a positioning prompt light of the remote control key in response to the control of the vehicle control module.

[0094] Optionally, in a possible implementation of this embodiment, the remote control key positioning system may further include multiple controller area network (CAN) buses and gateways (GW). The CAN bus includes a CAN1 bus and a CAN2 bus. The vehicle control module, the central control module, and the PEPS module may communicate with each other via the CAN1 bus, the CAN2 bus, and the gateway GW.

[0095] Optionally, in a possible implementation of this embodiment, the vehicle control module may include an onboard control module (Electronic Control Unit, ECU). The central control module may include a central control multi-function display controller (Multi-function Control System, MCS), that is, a central control screen. CAN1 may include an entertainment information bus. CAN2 may include a body information bus.

[0096] In this embodiment, Figure 3 It is a schematic diagram of the architecture of a system for locating a remote control key in an application scenario provided by another embodiment of the present application.

[0097] For example, Figure 3As shown, the application scenario of the remote control key positioning system may include the vehicle control module ECU, the central control screen, the PEPS module, 6 low-frequency antennas, the remote control key and multiple speakers. Among them, the remote control key positioning system may include the vehicle control module ECU, the central control screen MCS, the PEPS module, 6 low-frequency antennas and multiple speakers. CAN1 is the entertainment information CAN, and CAN1 can be used to control the communication between the gateway GW, the central control screen, and the vehicle control module ECU. CAN2 is the body information CAN. CAN2 can be used to control the communication between the gateway GW, the vehicle control module ECU, the PEPS module, and the low-frequency antenna.

[0098] Here, if Figure 3 As shown, first, the central control screen can select and operate the soft switch to turn on the key-finding function through the driver, and use CAN1 to send the key-finding function turn-on signal, that is, the positioning request information of the remote control key, to the gateway GW. Secondly, the gateway GW sends the key-finding function turn-on signal to the PEPS module through CAN2. Thirdly, after receiving the key-finding function turn-on signal, the PEPS module drives the low-frequency antenna to send a low-frequency signal. Thirdly, after the remote control key in the car receives the low-frequency signal sent by different low-frequency antennas, the low-frequency signal and the corresponding field strength value of each low-frequency antenna can be obtained. Thirdly, the remote control key in the car processes the low-frequency signal value and the corresponding field strength value of each low-frequency antenna to obtain the corresponding high-frequency signal data, that is, the high-frequency signal value and the corresponding field strength value, and sends the high-frequency signal data to the high-frequency receiver of the PEPS module. Thirdly, the high-frequency receiver of the PEPS receives the high-frequency signal data sent by the remote control key, sends it to CAN1 through GW, and then sends the high-frequency signal data to the vehicle control module ECU through CAN1. Again, the vehicle control unit ECU converts and processes the high-frequency signal data to obtain the low-frequency signal value and field strength value corresponding to the high-frequency signal data, and then analyzes and processes multiple low-frequency signal values ​​and field strength values ​​to obtain the relative position information of the remote control key in the car. Again, based on the relative position information of the remote control key in the car, the vehicle control unit ECU drives different speakers in the car to work and determines the speaker closest to the remote control key. Finally, the volume output of the speaker close to the key position can be enhanced according to the key position. Play specific prompt sound effects, such as beeps, voice prompts, or music clips. Here, the prompt sound effect can be in a loop or gradual increase mode to ensure that the driver can quickly lock the key position.

[0099] Here, it can be understood that after the remote control key receives multiple low-frequency signals, these low-frequency signals can be converted into a high-frequency signal and sent to the vehicle controller ECU. Specifically, these low-frequency signals can be converted into a high-frequency signal through a conversion module such as an amplifier circuit or a frequency converter. 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 in the remote control key, 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 include different low-frequency signals, that is, each message segment includes a low-frequency signal information, for example, including 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. After the vehicle controller ECU receives the high-frequency signal, the high-frequency signal can be parsed to restore multiple low-frequency signals. Since the low-frequency antennas that emit these low-frequency signals are distributed in different positions in the car, the field strength of each low-frequency signal received by the remote control key is also different. Among them, the low-frequency signal emitted by the low-frequency antenna that is closer to the remote control key has a larger field strength, while the low-frequency signal emitted by the low-frequency antenna that is farther away has a smaller field strength. 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 remote control key, and then the remote control key can be located according to the position identifier carried by the low-frequency signal with the largest field strength.

[0100] The solution in this embodiment can realize an intuitive sound prompt of the key position in the car by combining the sound field adjustment function of the car audio system, thereby solving the problem of difficulty for users to find the key.

[0101] In addition, by adopting the solution in this embodiment, by combining the sound field adjustment function of the vehicle audio system and the light color prompt function of the lighting equipment, it is possible to further achieve an intuitive sound prompt of the key position in the car, thereby solving the problem of users having difficulty finding the key.
