[0002] The application of voice control technology brings many conveniences to drivers and passengers, while also eliminating the potential safety hazards caused by traditional button operations. The existing vehicle voice recognition circuit can only receive in-vehicle call voices and voice control vehicle operation commands, which requires the voice control function to meet two conditions, namely, the vehicle is powered on and the person who issues the voice command is in the vehicle, which greatly limits the user experience of the voice control function.

BRIEF DESCRIPTION OF THE DRAWINGS

[0009] The following is a brief description of the contents and symbols in the drawings of this specification:

[0010] Figure 1 It is a schematic diagram of the present invention. DETAILED DESCRIPTION

[0011] The specific implementation of the present invention is further described in detail below through description of embodiments in conjunction with the accompanying drawings.

[0012] As attached Figure 1 As shown, in order to realize voice control of the vehicle, a voice control component 30 is required. The body control module 10 is electrically connected to the voice control component 30 and other vehicle-mounted electrical appliances 20. After the body control module 10 receives the owner's control instructions uploaded by the voice control component 30, it issues instructions to drive other vehicle-mounted electrical appliances 20 to complete the control action.

[0013] In order to realize voice control of the vehicle by the driver and passengers inside and outside the vehicle cabin, the voice control component 30 includes a microphone 1 31 arranged on the outside of the vehicle body and a microphone 2 32 arranged in the vehicle cabin. The microphone 1 31 is used to collect voice information outside the vehicle cabin, and the microphone 2 32 is used to collect voice information inside the vehicle cabin. Specifically, the microphone 2 32 is arranged at the steering wheel, and the microphone 1 31 should be arranged at the front of the vehicle body. This requires that it is used to issue voice control commands at the front of the vehicle. On the one hand, this requires the user to observe and identify the vehicle. On the other hand, when the microphone 2 32 is damaged, the microphone 1 31 can also collect the vehicle control commands issued by the driver at the front of the vehicle. In this embodiment, a microphone 1 31 is arranged at the A-pillars on both sides of the vehicle body.

[0014] Furthermore, microphone 1 31 and microphone 2 32 are electrically connected to the voice receiving switching circuit 33, respectively. In this embodiment, the voice receiving switching circuit 33 controls microphone 1 31 or microphone 2 32 to collect voice signals, that is, microphone 1 31 and microphone 2 32 do not work at the same time, so as to avoid system errors caused by different users issuing voice control commands inside and outside the cabin at the same time. In other embodiments, the voice receiving switching circuit 33 can also control microphone 1 31 and microphone 2 32 to work at the same time, but in order to ensure the riding comfort and safety of the driver and passengers in the cabin, in this embodiment, the priority of the voice control command issued in the cabin is higher than the voice control command issued outside the cabin, that is, the priority of the voice information collected by microphone 2 32 is higher than the voice information collected by microphone 1 31.

[0015] Preferably, when the vehicle is in the parking state and the door is locked, the voice receiving switching circuit 33 is connected to the microphone 1 31, and the microphone 1 31 is started and collects voice signals, so that the user can unlock the vehicle and turn on the air conditioner outside the cabin. When the door is unlocked, the user can easily enter the cabin, so the voice receiving switching circuit 33 is connected to the microphone 2 32, and the microphone 2 32 is started and collects voice signals, so that the user can complete the functions of ignition, opening and closing the door, lifting and lowering the window, etc. through voice control commands in the cabin.

[0016] The voice signals collected by microphone 1 31 and microphone 2 32 are uploaded to the voice signal processing and recognition module 34 via the voice receiving switching circuit 33. The voice signal processing and recognition module 34 analyzes and recognizes the voice signals to obtain command information and uploads the command information to the body control module 10. The body control module 10 sends a command to the vehicle-mounted electrical appliance 20 to complete the vehicle control action of the specified information.

[0017] The body control module 10 is electrically connected to the voice control component 30 through the energy consumption management module 40, and the energy consumption management module 40 supplies power to the voice control component 30 when the vehicle is in a power-off state. In the prior art, the body control module 10 has the functions of unlocking the vehicle when it is parked and powered off, and realizing the lifting and lowering of the windows. The body control module 10 controls the energy consumption management module 40 to supply power to the voice control component 30 when the vehicle is powered off, and can realize voice control of the vehicle inside and outside the cabin at a low cost when the vehicle is powered off. In addition, existing vehicles usually have a body control module 10, and this embodiment realizes the voice control function based on the body control module 10. In this way, it is only necessary to add a microphone 1 31 to the body, a microphone 2 32 inside the vehicle, and update the control program of the body control module 10, so that existing vehicles can also conveniently realize the voice control function, greatly improving the scope of application of the voice control function.

[0018] Specifically, in order to reduce energy consumption while ensuring the effective realization of the voice control function when the vehicle is parked and powered off, when the vehicle is in the parking state and the door is locked, the energy consumption management module 40 is connected to the voice receiving switching circuit 33 to control the intermittent operation of the microphone 1 31, and the microphone 1 31 alternately enters the voice collection working state and the standby working state. Furthermore, a relatively short voice wake-up instruction should be used. In the intermittent working mode, the single voice collection working time t1 of the microphone 1 31 is less than the single standby time t2, which further reduces the energy consumption of the voice idle vehicle.

[0019] When the microphone 131 collects the voice signal and recognizes the wake-up sound, the energy consumption management module 40 is connected to the voice signal processing and recognition module 34, and the voice signal processing and recognition module 34 first compares whether the voice signal collected by the microphone 131 is consistent with the pre-stored user voice signal. If the voice signal collected by the microphone 131 is consistent with the pre-stored user voice signal, the body control module 10 is awakened, the valid instruction information in the voice signal is recognized and uploaded to the body control module 10 and the instruction is executed; if the voice signal collected by the microphone 131 is inconsistent with the pre-stored user voice signal, the microphone 131 resumes the intermittent working state.
