As shown in fig. 1 to fig. 3, an embodiment of a first aspect of the present application provides an in-vehicle key 100, including: a display module 10, a control unit 20 and a key switch 30. Wherein the content of the first and second substances,

the display module 10 can emit different colors of indicating light, and the different colors correspond to the functions to be executed in the key function set one by one.

For example, the display module 10 may include a plurality of LEDs (Light Emitting diodes) with different Light colors, in one case, the first LED driving circuit may be arranged to individually control the LEDs with different Light colors to emit Light, so as to enable the display module 10 to emit indication lights with different colors; in another case, the operating states of the LEDs with different light colors may be adjusted by setting the second LED driving circuit to adjust the color of the indication light emitted by the display module 10, in which case, the indication light emitted by the display module 10 may satisfy more color requirements without being limited to the light colors of the single LED, so as to form a one-to-one correspondence relationship with more different functions to be executed.

The key function set may be understood to include a set of all functions to be executed in the vehicle, which may be controlled by the vehicle-mounted key 100, and in some embodiments, the vehicle-mounted key 100 may be a key provided on a steering wheel, a key provided on a center console, or a key provided in another location of the vehicle. For each function to be executed, an indication light color can be specified in advance to represent the function to be executed, and then a corresponding rule between the indication light color and the function to be executed is established. For example, red indicating light may be designated to indicate a "temperature up" function, blue indicating light may be designated to indicate a "temperature down" function, green indicating light may be designated to indicate a "circulation air exchange" function, and the like, and specifically, a correspondence rule between the color of the indicating light and the function to be executed may be reasonably established according to practical applications, where the correspondence rule may be set by the vehicle when the vehicle leaves the factory, or may be set or modified by a user in a customized manner according to the habit of the user.

The control unit 20 is connected with the display module 10 and the vehicle function management device 500; the control unit 20 is configured to: and receiving a function updating signal sent by the vehicle function management device 500, and controlling the display module to emit indicating light with a specified color based on the function updating signal, wherein the function updating signal carries associated information of a current function to be executed, and the specified color corresponds to the current function to be executed.

For example, the vehicle function management device 500 may determine, in response to detecting a target signal in the in-vehicle data, a function currently to be executed in the set of key functions based on the target signal; and generating a function updating signal carrying the associated information of the current function to be executed, and sending the function updating signal to the vehicle-mounted key 100.

Illustratively, the vehicle function management device 500 may be a HUT (head unit, terminal information display unit); the vehicle using data can be partially or completely acquired by information acquisition equipment configured on the vehicle, and include but are not limited to vehicle gear state information, brake pedal state information, vehicle-mounted multimedia state information, vehicle-mounted air conditioner state information, windscreen wiper state information, user voice information and the like; the information acquisition equipment can comprise a plurality of sensors, such as a reversing radar, a camera, a rainfall sensor and the like, and can also comprise other data detection modules in the vehicle, such as a voice recognition module and the like; the method for acquiring the vehicle data implemented by the information acquisition device is not limited in the present application, and for example, the vehicle data may be acquired once every first preset time (e.g., 100ms, 500ms, or 1 s), or the vehicle data may be acquired in real time.

Further, for example, in one case, the target signal may be a vehicle state switching signal, which may be understood as: the method includes the steps that a signal triggered when vehicle using state information (such as vehicle gear state information, vehicle-mounted multimedia state information, vehicle-mounted air conditioner state information, wiper state information and the like) in vehicle using data is detected to change is detected, current vehicle using state information after switching can be carried in the vehicle using state switching signal, for example, in the vehicle using state switching signal triggered when the vehicle gear state information in the vehicle using data is switched from forward gear using information to reverse gear using information, the current vehicle using state information carried correspondingly is reverse gear using information; when the vehicle-mounted multimedia state information in the vehicle using data is detected to be switched into the music playing information from the standby state information, the corresponding carried current vehicle using state information is the music playing information, and the like. In one embodiment, a vehicle-using state judgment model can be deployed in a T-BOX (Telematics BOX), the vehicle-using state judgment model sends a control message through a vehicle local area network bus and realizes vehicle control, and current vehicle-using state information shared by Ethernet in a vehicle is received within a second preset time; or the current state information of using the car can be transmitted through communication modes such as wireless wifi and Bluetooth, and the method for acquiring the current state information of using the car is not specifically limited.

In the case that the target signal is the car-using state switching signal, the vehicle function management device 500 may further determine the current car-using state after switching based on the car-using state switching signal; and determining at least one recommended to-be-executed function in the key function set as the current to-be-executed function according to a preset recommendation rule based on the current vehicle using state.

For example, the vehicle function management device 500 may determine the current vehicle using state based on the current vehicle using state information carried in the vehicle using state switching signal, for example, if the vehicle using state switching signal carries the reverse gear using information, the current vehicle using state may be determined as the reverse state; if the vehicle-using state switching signal carries forward gear using information, the current vehicle-using state can be judged to be a driving state.

In one embodiment, a plurality of historical events in each vehicle using state can be obtained in advance, the function to be executed with the highest user use frequency in the vehicle using state is screened out from the historical events to be used as a sample, a preset neural network model is trained, the trained neural network model can automatically match the function to be executed with the highest user use frequency in the vehicle using state in a key function set according to different vehicle using states to be used as the current function to be executed, and the trained neural network model can be used as a preset recommendation rule. In this embodiment, the vehicle function management device 500 may automatically match a function to be executed, which is currently more suitable for the user's use requirement, for the user as the current function to be executed according to the current vehicle use state by using the preset recommendation rule, so as to improve the user experience of the user.

In another embodiment, the corresponding relationship between the vehicle state and each function to be executed in the key function set may also be pre-established for different vehicle use states to form a function recommendation table as a preset recommendation rule. In this embodiment, based on the current vehicle using state, a to-be-executed function having a corresponding relationship as in the recommendation rule with the current vehicle using state may be searched in the key function set according to a preset recommendation rule as the current to-be-executed function. For example, the reverse state may correspond to a reverse image viewing angle adjusting function in the recommendation rule, the parking state may correspond to a video playback adjusting function in the recommendation rule, and the like, and the recommendation rule may be a function recommendation table set when the vehicle leaves the factory, or a function recommendation table set or modified by a user in a user-defined manner according to the usage habit of the user.

Alternatively, the target signal may be a voice command signal, which may be understood as: the signal triggered when the user voice information in the user data is detected to include the preset keyword, for example, the user voice information in the user data may be acquired by a microphone, and the microphone may be disposed on the voice recognition module, or may be disposed on a controller (such as the vehicle-mounted key 100) of the voice recognition module, which is not specifically limited in this application. The preset keywords may be determined according to each function type in the key function set, for example, the keywords corresponding to the function of adjusting the viewing angle of the reverse image may include "reverse", "viewing angle", "overlook", and the like; the keywords corresponding to the music playing adjusting function may include "volume", "previous song", "next song", and the like. For further example, a pre-trained acoustic model may be set in the speech recognition module, and when the user speech information is input into the acoustic model, the acoustic model may extract acoustic features of the user speech information; judging whether the user voice information contains at least one keyword according to the acoustic characteristics of the user voice information, and outputting a voice instruction signal carrying the at least one keyword when the user voice information is judged to contain the at least one keyword, wherein the acoustic characteristics can be MFCC (Mel-Frequency cepstral coefficients) characteristics, PLP (Linear Predictive Coding) characteristics or Filterbank (Filter bank) characteristics and the like.

In the case that the target signal is a voice instruction signal, the vehicle function management device 500 may further analyze the voice instruction signal, and match one to-be-executed function in the key function set as the current to-be-executed function according to the analysis result.

For example, the voice command signal carries at least one keyword, the vehicle function management device 500 may parse the voice command signal to extract a text of the at least one keyword as a parsing result, and match a function to be executed with a maximum degree of association with the at least one keyword in the key function set as a current function to be executed according to the parsing result. Therefore, the user can freely switch the current function to be executed in a voice mode, the operation is more convenient, and the user experience is more favorably improved.

In one case, the associated information of the current function to be executed may be information of a designated color corresponding to the current function to be executed. For example, after determining the current function to be executed in the set of key functions based on the target signal, the vehicle function management device 500 may match information of a specified color corresponding to the current function to be executed as the associated information of the current function to be executed according to the rule of correspondence between the color of the indicating light and the function to be executed. In this way, after the control unit 20 receives the function update signal, the designated color corresponding to the current to-be-executed function can be determined directly according to the associated information of the current to-be-executed function carried in the function update signal, and the control unit 20 does not need to prestore the corresponding rule between the color of the indication light and the to-be-executed function, so that the storage space and the operation process of the control unit 20 can be saved, so that the control unit 20 can respond more quickly after receiving the function update signal, and the color of the indication light emitted by the display module 10 is switched to the designated color, thereby improving the timeliness of showing the current to-be-executed function correspondingly controlled by the vehicle-mounted key 100 to a user.

The key switch 30 includes a control terminal 31 and a sensing terminal 32, the control terminal 31 is connected to the control unit 20, and the control terminal 31 is configured to: when the sensing terminal 32 triggers the first key event, the control unit 20 sends a first function starting instruction to the vehicle function management device 500, so that the vehicle function management device 500 starts an execution process of a current function to be executed.

For example, a control rule may be preset, where the control rule includes an association relationship between a key event triggered by the sensing terminal 32 and a control signal transmitted by the control terminal 31 to the control unit 20, and the key switch 30 is configured according to the control rule, so that when the sensing terminal 32 of the key switch 30 triggers a key event, the control terminal 31 transmits the control signal associated with the key event to the control unit 20. In one case, the different key events may be events triggered by different operation modes of the sensing terminal 32. Illustratively, the different operation modes may include touch, press, slide and other operation modes, and may also include various combination operation modes combining touch, press and slide; the touch may include short touch, long touch, n times of continuous short touch (n is an integer and is greater than or equal to 2) and other operation modes, and the pressing may include short press, long press, n times of continuous short press and other operation modes.

For example, the sensing terminal 32 may be configured to trigger a first key event through a short-press operation mode, and correspondingly, when the sensing terminal 32 triggers the first key event, the control signal transmitted by the control terminal 31 to the control unit 20 is a signal for prompting the control unit 20 to send a first function starting instruction for starting an execution flow of a current function to be executed to the vehicle function management device 500; the sensing terminal 32 is set to trigger other key events through other operation modes, and correspondingly, when the sensing terminal 32 triggers other key events, the control signal transmitted by the control terminal 31 to the control unit 20 is a signal for prompting the control unit 20 to send an other function starting instruction for starting an execution flow of other specific functions to be executed to the vehicle function management device 500. Thus, the first key event triggered by the sensing terminal 32 is distinguished from other key events: the control of the current to-be-executed function and the control of the specific to-be-executed function can enable the vehicle-mounted key 100 to control the current to-be-executed function corresponding to the current indication light color, and meanwhile, the control of at least one specific to-be-executed function can be fixedly realized, so that the arrangement of the vehicle-mounted key 100 for controlling different to-be-executed functions is further reduced, the number of the vehicle-mounted keys 100 is reduced, and the use experience of a user is better improved.

In an embodiment of the present application, taking the voice recognition function as a specific function to be executed of any vehicle-mounted key 100, the key switch 30 of the vehicle-mounted key 100 may further be configured to: when the sensing terminal 32 triggers the second key event, the control unit 20 sends a voice function starting instruction to the vehicle function management device 500, so that the vehicle function management device 500 starts an execution process of the voice recognition function. The second key event may be triggered by the sensing terminal 32 by a long-press operation, for example. In this embodiment, the vehicle-mounted key 100 can also fixedly realize the control of the voice recognition function while controlling the current to-be-executed function corresponding to the current color of the indicating light, so that the user can start the voice recognition function at any time by operating the vehicle-mounted key 100, the voice recognition module is utilized to collect voice information of the user, and then the current to-be-executed function is switched at will in a voice mode, thereby better improving the user experience.

In some embodiments of the present application, as shown in fig. 2, the control unit 20 may also be configured to: updating and storing the color information of the current indicator light prestored by the device as the information of the specified color corresponding to the current function to be executed based on the associated information of the current function to be executed carried in the function updating signal; when the sensing terminal 32 triggers the first key event, a first function starting instruction carrying the color information of the current indicator light is sent to the vehicle function management device 500. So that the vehicle function management device 500 may match the blending instruction of the current function to be executed corresponding to the specified color according to the corresponding relationship between the color of the indicator light and the function blending instruction based on the current color information of the indicator light in the first function starting instruction, and send the blending instruction to the external device 600, so as to start the execution flow of the current function to be executed by the external device 600.

According to different functions to be executed, the external device 600 may include different target devices such as a voice recognition module, a music player, a vehicle-mounted air conditioner, a seat adjustment module, and a sunroof control module, and a receiving end of the deployment instruction of the current function to be executed is a target device corresponding to the current function to be executed in the external device 600. Taking the case that the current function to be executed is temperature-increased as an example, the target device corresponding to the current function to be executed should be a vehicle-mounted air conditioner, and by sending a preset allocation instruction of the current function to be executed to the external device 600, the vehicle-mounted air conditioner in the external device 600 receives and responds to the preset allocation instruction, so as to start the execution process of temperature increase.

The vehicle function management device 500 matches the deployment instruction with the first function starting instruction carrying the color information of the current indicator light fed back by the control unit 20 to correspondingly start the execution flow of the external device 600 on the current to-be-executed function, and then, after responding to the detected target signal to determine the current to-be-executed function, the vehicle function management device 500 does not need to keep the memory of the current to-be-executed function, and only after the induction end 32 of the key switch 30 triggers the first key event, the vehicle function management device responds and starts the execution flow of the current to-be-executed function, so that the operation burden of the vehicle function management device 500 can be reduced, the accuracy of the vehicle-mounted key 100 in controlling each to-be-executed function is improved, and the use experience of a user is improved.

In some embodiments of the present application, the control unit 20 may be further configured to: when the first function starting instruction is successfully sent, the display module 10 is controlled to emit the indication light which flickers at the specified frequency. Therefore, the user is reminded of successfully operating the control on the current function to be executed, the possibility of misoperation caused by repeated operation of the user is reduced, and the use experience of the user is better.

According to the vehicle-mounted key 100 provided by the embodiment of the first aspect of the present application, the display module 10 may emit the indication lights with the colors corresponding to different functions to be executed, and the control unit 20 controls the display module 10 to emit the indication light with the specified color corresponding to the current function to be executed based on the function update signal sent by the vehicle function management device 500; when the sensing end 32 of the key switch 30 triggers the first key event, a first function starting instruction for starting an execution process of a current function to be executed is sent to the vehicle function management device 500, so that the aim of controlling different functions to be executed by applying the vehicle-mounted key 100 can be fulfilled, the arrangement of the vehicle-mounted keys is simplified, and the number of the vehicle-mounted keys is reduced; moreover, the current function to be executed controlled corresponding to the vehicle-mounted key 100 can be more clearly indicated to the user by using the color of the indicating light of the display module 10, so as to reduce the possibility of misoperation of the user, thereby improving the use experience of the user.

For example, the key switch 30 of the vehicle-mounted key 100 may be a micro switch, the action reed of the micro switch is used as the sensing terminal 32, one end of the micro switch including the fixed contact is used as the control terminal 31, and the action reed and the fixed contact are quickly connected or disconnected through an external force, so as to implement a key event triggered by the sensing terminal 32. In one case, the user presses the key panel 82 on the steering wheel 800, so that the key panel 82 moves towards the side close to the control end 31 of the key switch 30 along the depth direction of the opening, and the sensing end 32 of the key switch 30 can be driven to trigger a key event, so that the operation is more convenient; moreover, the light emitting surface of the display module 10 faces the display area 802 of the key panel 82, and a user can know the color of the indicating light currently emitted by the display module 10 by observing the display area 802.
