[0029] In a first aspect, the present application provides a vehicle instrument device 10 , wherein the vehicle to which the vehicle instrument device 10 is applied is a new energy vehicle that can use electric energy as a driving energy source and be driven by a driving motor.

[0030] Figure 1 It is a structural block diagram of an embodiment of the vehicle instrument device 10 provided by the present application.

[0031] Combination Figure 1 The vehicle instrument device 10 includes a controller 11 and a sound processing module 12. The sound processing module 12 is connected to the controller 11. The sound processing module 12 is used to process sound data, and the sound data is used for external speakers to make sounds.

[0032] Specifically, the controller 11 can be a microcontroller unit (MCU), which is also called a single chip microcomputer (Single Chip Microcomputer) or a single chip microcomputer. The controller 11 controls the entire vehicle instrument device 10 so that the various components of the vehicle instrument device 10 work together to perform their functions. The sound processing module 12 processes the sound data, specifically, it can be to perform sound effect synthesis processing, amplification processing, etc. on the original sound data to obtain sound data that the speaker can directly use to output sound. The original sound data can be the sound data stored in the sound processing module 12, or it can be sound data input from the outside, without specific limitation. The speaker is connected to the sound processing module 12, and the speaker can receive the sound data processed by the sound processing module 12 to make sound based on the sound data.

[0033] It should be understood that the instrument device in the prior art does not have a sound processing module 12, because the existing instrument device does not have the need to process sound data. The present application integrates the sound processing module 12 in the instrument device, which can meet the need for sound data processing and lay the foundation for the generation of the speaker.

[0034] Continue to combine Figure 1 The vehicle instrument device 10 further includes an alarm switch 13, which is connected to the controller 11 and is used to input a user instruction to the controller 11. The alarm switch 13 may be a mechanical switch, in which case the user may mechanically press, rotate, or otherwise cause the alarm switch 13 to generate a user instruction. The alarm switch 13 may also be a virtual switch on the instrument display screen, in which case the user may touch or otherwise cause the alarm switch 13 to generate a user instruction. The user instruction generated by the alarm switch 13 will be further transmitted to the controller 11, so that the controller 11 can perform control based on the user instruction.

[0035] Among them, regarding the specific setting mode of the alarm switch 13, the alarm switch 13 can be set separately, and the alarm switch 13 is only related to the low speed alarm function of the vehicle. The alarm switch 13 can also be integrated with other switches in the vehicle instrument device 10, so that the alarm switch 13 can also realize other functions.

[0036] In combination with the above content, the controller 11 can obtain the current speed of the vehicle. When the controller 11 determines that the speed is less than the preset value, it controls the sound processing module 12 to work, and then makes the sound processing module 12 output the processed sound data, so that the speaker emits an alarm based on the sound data. In this setting mode, as long as the speed of the vehicle is lower than the preset value, the speaker will emit an alarm to alert the user.

[0037] In some application scenarios, the user does not want the speaker to emit an alarm sound. In this case, the user can input a user instruction through the alarm switch 13 and transmit it to the controller 11. The user instruction is actually a user instruction to turn off the alarm sound. When the controller 11 receives the user instruction through the alarm switch 13, the controller 11 can further control the sound processing module 12 to stop working. At this time, the sound processing module 12 will not output sound data to the speaker, so that the speaker stops emitting an alarm sound.

[0038] In summary, the vehicle instrument device 10 provided by the present application outputs sound data to the speaker through the sound processing module 12, realizes the speaker alarm in the low-speed state, and can integrate the low-speed alarm function into the vehicle instrument device 10, with high universality and low cost. In addition, the user can output a user instruction through the alarm switch 13 to stop the speaker from alarming.

[0039] Figure 2 It is a structural block diagram of another embodiment of the vehicle instrument device 10 provided by the present application.

[0040] Combination Figure 2 In some specific embodiments, the vehicle instrument device 10 further includes a signal acquisition module 14 , which is connected to the controller 11 and the alarm switch 13 . The signal acquisition module 14 is used to collect user instructions input by the alarm switch 13 and send a shutdown instruction to the controller 11 .

[0041] In this embodiment, the alarm switch 13 is indirectly connected to the controller 11 through the signal acquisition module 14, and the user command generated by the alarm switch 13 will be collected by the signal acquisition module 14, and the signal acquisition module 14 further sends the user command to the controller 11. It should be understood that in this setting, the alarm switch 13 is independent of other switch settings of the vehicle instrument device 10, and the alarm switch 13 only has the command collection function under the low speed warning.

[0042] Figure 3 It is a structural block diagram of another embodiment of the vehicle instrument device 10 provided in the present application.

[0043] Combination Figure 2 as well as Figure 3 In some specific embodiments, the signal acquisition module 14 includes a transceiver module 141 and an acquisition module 142. The transceiver module 141 is used to receive the vehicle speed information and send it to the controller 11. The acquisition module 142 is used to collect user instructions from the alarm switch 13 and send it to the controller 11.

[0044] At this time, the controller 11 obtains the vehicle speed information through the transceiver module 141. The transceiver module 141 can not only obtain the vehicle speed information, but also receive the gear information of the vehicle, and then the controller 11 controls the operation of other devices or controls the display based on the information received by the transceiver module 141. The acquisition module 142 is used alone to collect user instructions. At this time, the acquisition module 142 can directly collect the user instructions formed by the alarm switch 13 and directly send the user instructions to the controller 11.

[0045] As for a more specific configuration of the transceiver module 141 and the acquisition module 142 , in some specific embodiments, the transceiver module 141 is a CAN transceiver chip, which is used to receive vehicle speed information from the vehicle's CAN bus, and the acquisition module 142 is a hard-wired component.

[0046] It should be understood that CAN is the abbreviation of Controller Area Network, which is an ISO internationally standardized serial communication protocol. Correspondingly, the CAN bus is a data transmission line used to transmit data between different devices. The CAN transceiver chip corresponds to the CAN bus, so it can receive vehicle speed information from the CAN bus. The hard line of the vehicle is a data transmission line on the vehicle, and the hard line component is a data transmission line that can collect user command information of the alarm switch.

[0047] Figure 4 It is a structural block diagram of another embodiment of the vehicle instrument device 10 provided in the present application.

[0048] Combination Figure 4 In some specific embodiments, the vehicle instrument device 10 further includes an indicator device 15, which is connected to the controller 11. The controller 11 is configured to control the indicator device 15 to emit light to indicate the low-speed driving state of the vehicle when receiving a user instruction.

[0049] In combination with the above content, when the controller 11 receives a user instruction, it will control the sound processing module 12 to stop working, thereby causing the sound processing module 12 to stop sending sound data to the speaker, and the speaker will stop sounding the alarm. In order to ensure that the user is reminded when driving at a low speed, the controller 11 will control the indicating device 15 to emit a light, thereby indicating the low-speed driving state of the vehicle through the light.

[0050] Therefore, in this embodiment, the light emitted by the indicating device 15 can replace the alarm sound emitted by the speaker, thereby meeting the user's indication needs in specific scenarios.

[0051] Figure 5 It is a structural block diagram of another embodiment of the vehicle instrument device 10 provided in the present application.

[0052] Combination Figure 5 Regarding the further setting method of the indicating device 15, in some specific embodiments, the indicating device 15 includes a driving member 151 and a light-emitting member 152. The driving member 151 is connected to the controller 11 and the light-emitting member 152 respectively. When the controller 11 receives a user instruction, it controls the driving member 151 to drive the light-emitting member 152 to emit light.

[0053] Specifically, the number of light-emitting elements 152 may be multiple, and the number of driving elements 151 may be one. In this case, multiple light-emitting elements 152 may be driven by one driving element 151, thereby making multiple light-emitting elements 152 emit light. In some application scenarios, the driving element 151 is an LED driver, and the light-emitting element 152 corresponds to an LED lamp. Of course, the specific arrangement of the driving element 151 and the light-emitting element 152 is not limited thereto.

[0054] Figure 6 It is a structural block diagram of another embodiment of the vehicle instrument device 10 provided in the present application.

[0055] Combination Figure 6 In some specific embodiments, the sound processing module 12 includes a voice processing chip 121 and a power amplifier 122. The voice processing chip 121 is used to process the sound data, and the power amplifier 122 is used to amplify the processed sound data and transmit it to the speaker.

[0056] Among them, the voice processing chip 121 is the main module for realizing the voice processing function in the sound processing module 12. At this time, the voice processing module can perform sound effect synthesis processing on the original sound data. The power amplifier 122 can further process the voice data processed by the voice processing module, and the specific processing can be to amplify the voice data. Of course, the sound processing module 12 can also include some other processing modules, which can be set according to the specific application scenario, and no specific limitation is made here.

[0057] It should be understood that the vehicle instrument device 10 may not include a speaker, in which case the speaker is an external device independent of the vehicle instrument device 10. However, in some specific embodiments, the vehicle instrument device 10 includes a speaker, which is connected to the sound processing module 12, and the speaker is used to receive the sound data sent by the sound processing module 12 and to make sounds based on the sound processing module 12. In this case, the speaker is integrated in the vehicle instrument device 10, and after the sound processing module 12 generates voice data, the speaker further receives the voice data and plays an alarm sound based on the voice data.

[0058] In order to ensure the normal operation of the vehicle instrument device 10, in some specific embodiments, the vehicle instrument device 10 further includes a power supply, which is respectively connected to the controller 11 and the sound processing module 12, and is used to supply power to the controller 11 and the sound processing module 12. It should be understood that the signal acquisition module 14, the alarm switch 13, etc. can all be directly powered from the controller 11.

[0059] The second aspect of the present application provides a vehicle, comprising any of the above-mentioned vehicle instrument devices 10. For the specific description of the vehicle instrument device 10, reference can be made to the contents of the above-mentioned embodiments, which will not be repeated here.

[0060] In summary, for the vehicle provided in the above embodiments, the specific application methods in some application scenarios are as follows:

[0061] Each time the vehicle meter device 10 is switched to the ON position, the low speed alarm function of the vehicle meter device 10 is initialized. At this time, the low speed alarm function is turned on, the alarm switch 13 is turned off, and the indicator device 15 does not work.

[0062] Further, the alarm switch 13 is detected to see if it has received a user command. If it has received a user command, it indicates that the user does not want the loudspeaker to emit an alarm sound. In this state, if the vehicle is in a low-speed driving state, the controller 11 drives the indicating device 15 to work to indicate the low-speed driving state of the vehicle.

[0063] If the alarm switch 13 does not receive a user command, then the mode of the vehicle is detected. When the vehicle is in the READY mode, the speed of the vehicle is detected. When the speed of the vehicle is less than a preset value, the sound processing module 12 is controlled to work, thereby making the speaker sound. In this application scenario, if it is detected that the alarm switch 13 receives a user command at this time, the sound processing module 12 is further controlled to stop working, and the indication module is controlled to start working.

[0064] In the embodiment of issuing an alarm sound through a speaker, assuming the preset value is 30km / h, then:

[0065] When the vehicle speed is between 0-20km / h, if it is in the forward gear, the volume of the alarm sound increases as the vehicle speed increases, and decreases as the vehicle speed decreases. At this time, the sound has a frequency shift. If it is in the reverse gear, the volume of the alarm sound is fixed.

[0066] When the vehicle speed is between 20km / h and 30km / h, if it is in the forward gear, the volume of the alarm sound decreases as the vehicle speed increases, and increases as the vehicle speed decreases. At this time, there is no frequency shift in the sound. If it is in the reverse gear, the volume of the alarm sound is fixed.

[0067] In summary, the vehicle instrument device 10 provided based on the present application includes: a controller 11; a sound processing module 12, connected to the controller 11, the sound processing module 12 is used to process sound data, and the sound data is used for an external speaker to make sound; an alarm switch 13, connected to the controller 11, the alarm switch 13 is used to input user instructions to the controller 11; wherein, when the controller 11 determines that the vehicle speed is less than a preset value, the sound processing module 12 is controlled to work so that the speaker emits an alarm sound, and when the controller 11 receives a user instruction through the alarm switch 13, the sound processing module 12 is controlled to stop working so that the speaker stops emitting an alarm sound.

[0068] Through the above configuration, in any of the above embodiments, the sound data processed by the sound processing module 12 is used by the speaker to make sound, so that the low-speed alarm function can be integrated into the vehicle instrument device 10, with a high degree of commonality and low cost.

[0069] The above description is only an optional embodiment of the present application, and does not limit the patent scope of the present application.
