Description

Technical Field

[0001] This utility model relates to the field of user vehicle control technology, and in particular to a voice control system for an electric two-wheeled vehicle. Background Technology

[0002] Currently, there are many ways for users to control electric bicycles and electric motorcycles, such as Bluetooth control, key control, remote control, password power-on / off, and voice control. While voice control is relatively simple to operate, current voice control systems still have the following problems: a mismatch between the voice recorded on the mobile device and the voice recognized by the user during voice control, making voice recognition highly susceptible to environmental parameters and unable to meet control needs in special scenarios. For example, when waking up the vehicle from a distance, it is easily affected by distance and angle, leading to control difficulties. Furthermore, because the instrument panel does not display when powered off, waking up the vehicle from a distance, especially in dark environments, can only be done through the audio system, easily causing noise pollution. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this utility model provides a voice control system for electric two-wheeled vehicles, aiming to solve the problems of poor sensitivity and difficulty in recognition caused by the significant influence of environmental factors and operating habits on voice control.

[0004] The technical solution adopted in this utility model is as follows:

[0005] A voice control system for an electric two-wheeled vehicle, comprising:

[0006] A microphone is used for recording voiceprint information and receiving voice input for control purposes.

[0007] The voiceprint module includes a voiceprint acquisition and recognition module and a first MCU module; the voiceprint acquisition and recognition module is connected to the microphone and is used to acquire and recognize voiceprints; the first MCU module is connected to the voiceprint acquisition and recognition module and is used to convert different voiceprint information into corresponding control codes.

[0008] A Bluetooth alarm module includes a second MCU module, a Bluetooth module, a driver module, and an electrical switch, all connected to the second MCU module; the second MCU module is connected to the first MCU module; the driver module is connected to the end to be driven.

[0009] The vehicle controller is connected to the second MCU module;

[0010] An instrument used to monitor communication data between the second MCU module and the first MCU module;

[0011] The APP unit, which connects to the Bluetooth alarm module via the Bluetooth module, is used to send recording commands and save the control codes replied by the voiceprint module.

[0012] The further technical solution is as follows:

[0013] The second MCU module is connected to the first MCU module via a single cable.

[0014] The instrument is connected to a single wire that connects the second MCU module and the first MCU module for monitoring.

[0015] The electrical switch is electrically connected to the instrument panel and the vehicle controller; the instrument panel is electrically connected to the vehicle lights.

[0016] The instrument panel is always powered. When the soundprint module sends the corresponding code to the Bluetooth alarm module, the instrument panel drives the headlights to display the corresponding information through the vehicle controller.

[0017] The second MCU module is connected to the vehicle controller via a single wire.

[0018] The first MCU module uses the STM32F407 chip.

[0019] The microphone is integrated into the handlebars or dashboard.

[0020] The Bluetooth alarm module also includes an alarm module, which includes a vibration sensor, a GPS module, and a distance sensor.

[0021] The end to be driven includes a saddle lock and a horn.

[0022] The beneficial effects of this utility model are as follows:

[0023] This utility model features a reasonable structural design and convenient operation. After the user's voiceprint has been learned, the vehicle can be powered on / off, the door locks unlocked, and other vehicle functions configured without the need for any additional equipment. Specifically, the voiceprint can be directly recorded via the vehicle's microphone, ensuring consistency between the voiceprint recorded for the same user and the voiceprint obtained from the input voice recognition during voice control. This avoids the limitations imposed by distance and angle when recording with mobile devices such as smartphones, improving the sensitivity and accuracy of long-distance voice control.

[0024] This invention also improves the flexibility of long-distance control, especially long-distance voice-activated activation in dark environments. The instrument panel can monitor communication messages and control the vehicle lights to illuminate based on voice input commands while the instrument is powered off, thus activating the vehicle and allowing users to quickly locate it while minimizing noise.

[0028] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0029] like Figure 1 As shown, the voice control system for the electric two-wheeled vehicle in this embodiment includes:

[0030] Microphone 1 is used for recording voiceprint information and receiving voice input for control.

[0031] The voiceprint module 2 includes a voiceprint acquisition and recognition module 21 and a first MCU module 22; the voiceprint acquisition and recognition module 21 is connected to a microphone 1 and is used to acquire and recognize voiceprints; the first MCU module 22 is connected to the voiceprint acquisition and recognition module 21 and is used to convert different voiceprint information into corresponding control codes.

[0032] Bluetooth alarm module 3 includes a second MCU module 31, a Bluetooth module 32, a driver module 33, and an electric switch 34, all connected to the second MCU module 31; the second MCU module 31 is connected to the first MCU module 22; and the driver module 33 is connected to the end to be driven.

[0033] The vehicle controller 6 is connected to the second MCU module 31;

[0034] Instrument 5 is used to monitor the communication data between the second MCU module 31 and the first MCU module 22;

[0035] The APP unit 4 is connected to the Bluetooth alarm module 3 via the Bluetooth module 32. It is used to send recording commands and save the control codes replied by the voiceprint module 2.

[0036] In this embodiment, microphone 1 serves as both a device for voiceprint recording and a device for voice input during voice control, ensuring consistency between the voiceprint recorded for the same object and the voiceprint obtained from the corresponding voice input during voice control. Furthermore, recording directly through microphone 1 avoids the limitations imposed by distance and angle that occur when using the APP unit 4 on a mobile phone, making operation convenient and highly stable. Preferably, microphone 1 is integrated into the handlebars or dashboard.

[0037] As a preferred embodiment, the second MCU module 31 and the first MCU module 22 are connected via a single wire.

[0038] As a preferred method, the instrument 5 is connected to the first MCU module 22 via a single-wire connection between the second MCU module 31 and the first MCU module 22 for monitoring.

[0039] As a preferred method, the second MCU module 31 is connected to the vehicle controller 6 via a single wire.

[0040] Specifically, the electric switch 34 is electrically connected to the instrument 5 and to the vehicle controller 6.

[0041] As a preferred method, the instrument cluster 5 is electrically connected to the vehicle lights.

[0042] As a preferred approach, both the first MCU module 22 and the second MCU module 31 use the STM32F407 chip.

[0043] Specifically, Bluetooth module 32 is mainly responsible for the connection and function configuration of APP unit 4, while driver module 33 is mainly responsible for speaker driving, saddle lock driving, and other tasks.

[0044] The working principle of this embodiment is as follows:

[0045] The APP unit 4 sends a recording command to the Bluetooth alarm module 3, which in turn sends the command to the voiceprint module 2. The voiceprint module 2 turns on the microphone 1, and the user records the voiceprint through the microphone 1. The voiceprint acquisition and recognition module 21 in the voiceprint module 2 saves the recorded voice according to the recording command, generates corresponding control code through the first MCU module 22, and sends the control code to the Bluetooth alarm module 3. The Bluetooth alarm module 3 executes the corresponding functions according to the control code, including controlling the operation of the power switch 34, the drive module 33, and the Bluetooth module 32 through the second MCU module 31.

[0046] Taking a specific application scenario as an example: The APP unit 4 sends a recorded power-on command to the Bluetooth alarm module 3, which in turn sends a request to the voiceprint module 2. The voiceprint acquisition and recognition module 21 begins to collect and save the voice corresponding to the power-on command. The first MCU module 22 generates the corresponding control code and sends it to the Bluetooth alarm module 3 for storage. During use, the user speaks the corresponding voice, the voiceprint module 2 detects the corresponding voiceprint, and sends the corresponding control code to the second MCU module 31 via the first MCU module 22. The second MCU module 31 matches the received control code with the stored control code. If a match is successful, it drives the power switch and unlocks the ignition lock according to the control code. The same method is used to unlock the saddle lock or implement other vehicle controls.

[0047] Specifically, the electric switch 34 controls the operation of the vehicle controller 6 and the instrument cluster 5. As an improvement, the instrument cluster 5 is constantly powered. When the voiceprint module 2 sends the corresponding code to the Bluetooth alarm module 3, the instrument cluster 5 drives the headlights to display the corresponding information via the vehicle controller 6. This allows for detection of voice recognition through light indicators; it also enables nighttime vehicle location via light indicators. For example, after recognizing a user's voice requesting the vehicle, the instrument cluster 5 drives the headlights to flash, indicating a vehicle response and meeting the needs of various scenarios.

[0048] Specifically, the instrument 5 displays information after being activated by the power switch 34 under normal conditions. After power-off, the display can be determined by detecting the one-wire communication message between the first MCU module 22 and the second MCU module 31.

[0049] Specifically, voiceprint module 2 can identify the voiceprints of different users. Only when information matching the recorded voiceprint and voice data is identified will control commands be sent. In practice, voiceprints of different users can be recorded to meet the needs of multiple family members.

[0050] Specifically, APP unit 4 can save the parameter combinations during different users' vehicle use, saving them as driving habit configurations. When different users' voices are detected, the control system automatically switches to the corresponding driving habit configuration, which includes average vehicle speed, gear, etc.

[0051] Specifically, APP unit 4 saves the code sent from the first MCU module 22 to the second MCU module 31. APP unit 4 can also request the deletion of the saved code by sending a deletion command to voiceprint module 2. Voiceprint module 2 then locates the corresponding voice information based on the code to be deleted and performs the deletion.

[0052] As a preferred method, the voiceprint module 2 has a factory-written independent code. The Bluetooth alarm module 3 first needs to identify the code corresponding to the voiceprint module 2, and then identify the corresponding control code to prevent cracking and control errors, and improve the security of use.

[0053] As an independent unit, the voiceprint module 2 is easy to replace. As long as the APP unit 4 deletes the original corresponding encoding and code, it can learn the new module by resending the learning command.

[0054] Specifically, the Bluetooth alarm module 3 also includes an alarm module, which includes a vibration sensor, a GPS module, and a distance sensor. When the vehicle experiences abnormal vibration or movement, a buzzer alarm can be triggered and a notification can be sent to the mobile APP unit; when the owner approaches the vehicle, the Bluetooth module automatically connects, the motor unlocks, and the vehicle can be started; when the owner leaves the vehicle, Bluetooth disconnects, the motor locks, and the vehicle enters armed mode.

[0055] It will be understood by those skilled in the art that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
