Description

Technical Field

[0001] The present application relates to the field of automobile technology, and in particular to a method, device, equipment and medium for controlling an automobile hood based on voice interaction. Background Art

[0002] In recent years, with the development of environmental protection and new energy technology, more and more cars have begun to use electricity as a power source. With the popularity of electric vehicles, the front cabin of the car is increasingly converted into storage space, and the frequency of opening and closing the hood will also increase.

[0003] However, due to safety requirements and restrictions, the car hood generally cannot be opened and closed automatically like an electric tailgate. In the relevant technology, the opening and closing process of most car hoods is: the user manually pulls the hood switch in the car to make the hood pop up, and then needs to manually open the hood hook in front of the car to unlock and open the hood. This way of opening the hood may cause the following troubles to the car owner: 1) Low opening and closing efficiency: It is time-consuming and labor-intensive to get off the car to manually open and close the hood; 2) There are many safety hazards: On the one hand, the user's hand needs to touch the hood. In the midsummer, the surface temperature of the hood can reach about 80°C, and there is a possibility of scalding the hand. On the other hand, the hands are easily scratched during the process of groping and opening the auxiliary hook. In the process of propping up or lowering the hood, the user's hands and shoulders are easily crushed due to the heavy hood.

[0055] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and are not to be construed as limitations on the present application. For the step numbers in the following embodiments, they are only provided for the convenience of explanation, and the order between the steps is not limited in any way, and the execution order of each step in the embodiment can be adaptively adjusted according to the understanding of those skilled in the art.

[0056] In recent years, with the development of environmental protection and new energy technology, more and more cars have begun to use electricity as a power source. With the popularity of electric vehicles, the front cabin of the car is increasingly converted into storage space, and the frequency of opening and closing the hood will also increase.

[0057] However, due to safety requirements and restrictions, the car hood generally cannot be opened and closed automatically like an electric tailgate. In the relevant technology, the opening and closing process of most car hoods is: the user manually pulls the hood switch in the car to make the hood pop up, and then needs to manually open the hood hook in front of the car to unlock and open the hood. This way of opening the hood may cause the following troubles to the car owner: 1) Low opening and closing efficiency: It is time-consuming and labor-intensive to get off the car to manually open and close the hood; 2) There are many safety hazards: On the one hand, the user's hand needs to touch the hood. In the midsummer, the surface temperature of the hood can reach about 80°C, and there is a possibility of scalding the hand. On the other hand, the hands are easily scratched during the process of groping and opening the auxiliary hook. In the process of propping up or lowering the hood, the user's hands and shoulders are easily crushed due to the heavy hood.

[0058] In view of this, a method for controlling a car hood based on voice interaction is provided in the embodiment of the present application. The method in the embodiment of the present application is mainly used in the field of automobile technology. The method can realize contactless opening of the car hood, which can greatly reduce the burden on users and improve the convenience of using the car; and the method eliminates the safety hazards when users fumble for the hook and prop up / lower the hood. In the process of opening the car hood, the user's instructions are confirmed multiple times through voice interaction, which can effectively improve the safety of hood control.

[0059] First, please refer to Figure 1 , Figure 1 Schematic diagram of the implementation environment of the vehicle hood control method based on voice interaction provided in the embodiment of the present application. Figure 1 The subject of the implementation environment mainly includes users and cars. Among them, the car hood control method based on voice interaction can be configured in a related controller in the car, and the embodiment of the present application does not specifically limit this.

[0060] Specifically, the car in the present application is equipped with a relevant voice interaction device, which can recognize the user's voice information on the one hand, and output preset voice information on the other hand to interact with the user. Figure 1 The implementation environment shown is used to introduce and illustrate the car hood control method based on voice interaction provided in the embodiment of the present application. Figure 2 , Figure 2 is a schematic diagram of a method for controlling a car hood based on voice interaction provided in an embodiment of the present application, and the method for controlling a car hood based on voice interaction includes but is not limited to:

[0061] Step 210: recognizing and verifying the user's first voice information through the voice interaction device;

[0062] In this step, when the user wants to open the hood of the car, a corresponding voice message can be sent to the car through the voice interaction device, and the message is recorded as the first voice message. Specifically, for example, the first voice message can be information such as "Please open the hood of the car", and this application does not impose specific restrictions on it. After receiving the first voice message, the voice interaction device can identify and verify it. Here, the semantics of the first voice message can be identified by a related artificial intelligence algorithm to detect whether the user wants to open the hood of the car.

[0063] Step 220: When the first voice information verification is passed, a first unlocking instruction is sent to the CAN system of the vehicle;

[0064] In this step, when the first voice message indicates that the user wants to open the hood of the car, it can be considered that the first voice message verification has passed. At this time, a start command will be triggered on the car, and this application records this command as the first unlocking command. The first unlocking command is used to start the automatic control process task of executing the car hood. After the command is generated, it will be automatically sent to the CAN system of the car for execution.

[0065] Step 230: The CAN system controls the hood to open and pop up in response to the first unlocking instruction, and outputs first inquiry information through the voice interaction device; the first inquiry information is used to inquire the user whether to perform secondary unlocking;

[0066] In this step, when the CAN system of the car receives the first unlocking instruction, the car hood will be unlocked at the first level according to the first unlocking instruction. Here, since the position of the hood after opening is important to the driving safety of the car, in order to prevent misoperation, it is generally necessary to set a two-level control logic to control the opening of the car hood. In the embodiment of the present application, the first unlocking instruction is used to achieve the first level unlocking. During the first level unlocking process, the car hood will change from a closed state to an open and pop-up state. Here, the pop-up hood is still restricted by the hook and cannot be opened directly, the purpose of which is to prevent misoperation from blocking the driver's sight.

[0067] Furthermore, in this step, the first inquiry information is also outputted through the voice interaction device, and the first inquiry information is used to inquire the user whether to perform the second-level unlocking. In this way, the unlocking process of the car hood can be confirmed with the user multiple times in an interactive manner to prevent the car hood from being accidentally opened, thereby improving the safety of car use. Specifically, in the embodiment of the present application, the content of the first inquiry information can be flexibly set as needed, for example, it can be "First-level unlocking is completed, are you sure to continue opening the hood?" This application does not impose specific restrictions on it.

[0068] Step 240: Identify and verify, through a voice interaction device, second voice information fed back by the user in response to the first inquiry information;

[0069] In this step, the voice information of the user's feedback to the first inquiry information is continuously recognized and verified through the voice interaction device, and recorded as the second voice information. The recognition and verification method of the second voice information is similar to that of the first voice information. For example, for the first inquiry information in the form of "Level 1 unlocking completed, are you sure you want to continue opening the hood?", when the second voice information is "yes / yes / right / right", etc., it can be considered that the second voice information has been verified.

[0070] Step 250: When the second voice information is verified, a second unlocking instruction is sent to the CAN system of the vehicle;

[0071] Step 260: In response to the second unlocking instruction, the CAN system controls the hook of the hood to open and drives the support rod of the hood to rise to a preset position.

[0072] In an embodiment of the present application, when the second voice information verification is passed, a second unlocking instruction can be sent to the CAN system of the car, and the CAN system of the car can perform the secondary unlocking task of the hood according to the second unlocking instruction. Here, the secondary unlocking refers to the opening of the hook of the car hood, so that the car can be in a state where the hood can be opened freely. Specifically, the action of opening the hook can be performed by a related motor, and this application does not limit this. When the hood becomes a state where it can be opened freely, the hood can be driven to open by a motor. Specifically, in an embodiment of the present application, the hood drive motor can be used to control the hood to lift a preset distance and then fix the support rod of the hood, thereby completing the hood opening operation.

[0073] It should be noted that, in the embodiments of the present application, the preset distance for controlling the lifting of the hood can be flexibly set as needed, and the present application does not impose any restrictions on this. For example, in some embodiments, during the process of controlling the lifting of the hood, the user can issue a voice command at any time to inform the car to complete the task of opening the hood. At this time, the hood will stop lifting and hover in the current position due to the action of the support rod. Specifically, for example, in some embodiments, the user can issue the command "HOLD" to the voice interaction device, and the hood will open to this height by default. In addition, in the embodiments of the present application, the system can automatically memorize the height, and during the next or subsequent opening process, it will automatically lift to this height and then stop, that is, use this height as the preset distance for lifting, so as to facilitate use by users of different heights.

[0074] In some embodiments, the CAN system controls the hood to open and pop up in response to the first unlocking instruction, including:

[0075] The CAN system detects whether the vehicle is in a parking state in response to the first unlocking instruction;

[0076] When the CAN system determines that the vehicle is in a parking state, the hood is controlled to open and pop up according to the first unlocking instruction.

[0077] In the embodiment of the present application, after the CAN system receives the first unlocking instruction, it can detect whether the car is in the parking state. Specifically, because the opening of the car hood may block the driver's line of sight. Therefore, for safety reasons, in the embodiment of the present application, when controlling the automatic opening of the car hood, it is necessary to detect whether the car is in the parking state. Here, the parking state refers to the state in which the car is currently stationary. In some embodiments, the speed of the car can be detected. When the speed of the car is 0 or close to 0, the car can be considered to be in the parking state. Specifically, a speed comparison threshold can be set. When the driving speed of the car is less than the comparison threshold, the car is considered to be in the parking state. In other embodiments, the position information of the car can also be detected. When the position of the car does not change within a period of time, the car can be considered to be in the parking state. It should be noted that the above embodiments are only used for exemplary descriptions of detecting whether the car is in the parking state, and do not limit the specific implementation of the present application.

[0078] When the CAN system determines that the vehicle is in a parking state, it means that opening the hood of the vehicle currently will not affect normal driving, and the hood can be controlled to open and pop up according to the first unlocking instruction.

[0079] In some embodiments, the CAN system controls the hook of the hood to open in response to the second unlocking instruction, including:

[0080] The CAN system detects whether the vehicle is in a parking state in response to the second unlocking instruction;

[0081] When the CAN system determines that the automobile is in a parking state, the hook of the hood is controlled to open according to the second unlocking instruction.

[0082] In the embodiment of the present application, as mentioned above, in order to prevent misoperation, it is necessary to set a two-level control logic to control the opening of the car hood. Therefore, when the CAN system receives the second unlocking instruction, it can respond to the second unlocking instruction to detect whether the car is in a parked state. Similarly, in some embodiments, the speed of the car can be detected. When the speed of the car is 0 or close to 0, it can be considered that the car is in a parked state. Specifically, a speed comparison threshold can be set. When the driving speed of the car is less than the comparison threshold, the car is considered to be in a parked state. In other embodiments, the position information of the car can also be detected. When the position of the car does not change within a period of time, it can be considered that the car is in a parked state.

[0083] When it is determined that the vehicle is in the parking state, the secondary unlocking task of the hood can be executed according to the second unlocking instruction.

[0084] In the embodiment of the present application, if the car is not in the parking state when the CAN system receives the first unlocking command or the second unlocking command, an error message can be displayed on the display of the car. The error message can be text information such as "the car is not currently stopped", and the specific content is not limited in the present application.

[0085] In some embodiments, the method further comprises:

[0086] Recognize and verify the user's third voice information through the voice interaction device;

[0087] When the third voice message is verified, a hood closing instruction is sent to the CAN system of the vehicle;

[0088] The CAN system controls the hood and the vehicle body to be completely closed in response to the hood closing instruction.

[0089] The car hood control method based on voice interaction provided in the embodiment of the present application also includes a solution for automatically controlling the hood closing. Specifically, when the user wants the car hood to be closed, a voice message of closing can be sent through voice interaction. In the embodiment of the present application, the voice message is recorded as the third voice message, and the voice interaction device can recognize and verify the user's third voice message. Similarly, when the third voice message is verified, a hood closing command can be sent to the car's CAN system, so that the CAN system responds to the hood closing command and controls the hood and the car body to be completely closed.

[0090] Specifically, in the embodiment of the present application, when the CAN system receives the hood closing command, it can detect whether the car is in the parking state. When the car is in the parking state, the hood can be controlled to close to a predetermined position according to the hood closing command, and then after the hood is closed to the predetermined position, the hood hook can be controlled to hook the hood and trigger the first-level locking command at the same time; this process is the second-level locking process. Then, according to the first-level locking command, the hood can be controlled to continue to close until it is completely closed with the car body. In this way, the automatic closing control of the car hood is completed.

[0091] In some embodiments, the method further comprises the following steps:

[0092] When the support rod of the hood is lifted to a preset position or the hood and the vehicle body are completely closed, a hood action prompt sound is output.

[0093] In the embodiment of the present application, when the car completes the task of opening and closing the hood, the corresponding hood action prompt sound can be output. For example, information such as "the car hood is opened / closed" can be output to remind the user. Of course, in some embodiments, during the process of raising or closing the car hood, a hood action prompt sound can also be output, such as information such as "the car hood is opening / closed", to remind relevant personnel to avoid and prevent unnecessary collisions and accidents such as pinching.

[0094] Below, in conjunction with specific embodiments, possible implementation methods of the present application are introduced and explained in detail.

[0095] When the car is opening its hood, the user can start the vehicle power supply, and at the same time, the car-side smart device with a human-machine voice interaction system starts up to wake up the voice assistant. At this time, the user can issue a voice command to the car-side smart device, "Hello XX, open the hood"; the voice assistant recognizes the command and confirms the command content again, "Are you sure you want to open the hood?"; the user replies to the command: yes / yes / right / right; the voice assistant confirms the reply command, answers "OK, I'll open the hood for you now," and sends the first unlock command to the CAN system; the CAN system performs a parking check, and if it is in the parking state, it sends an opening command to the hood lock electronic control unit; the electronic control unit of the hood lock electronic control unit accepts the command, the lock opens, and the result is fed back to the CAN system; after the CAN system recognizes that the hood lock is open, it sends the voice assistant's startup command to the smart device, and outputs the voice "Level 1 unlocking completed, are you sure you want to continue opening the hood?" At this time, the seat or steering wheel can vibrate for 1s, the ambient light lights up, and the display shows "Level 1 unlocking completed" to prompt the user to confirm; the user replies to the command: yes / yes / Yes / Yes; the voice assistant confirms the reply command and answers "OK, now open the hood for you", and sends the second unlocking command to the CAN system; the CAN system performs a parking check, and if the vehicle is in the parking state, it sends an opening command to the hood hook electronic control unit; the hood hook electronic control unit receives the command, opens the hood hook, and feeds back the opening result to the CAN system, at which time the seat or steering wheel vibrates for 1s, the brightness / color of the ambient light changes, and the display screen displays "Secondary unlocking completed"; after the CAN system recognizes that the hook is open, it performs a parking check, and if the vehicle is in the parking state, it sends an opening command to the electronic control unit of the hood hydraulic telescopic support rod; the electronic control unit of the hood hydraulic telescopic support rod receives the command, automatically pulls up the hood, and feeds back the opening result to the CAN system; during the hood lifting process, the buzzer emits a "beep-beep-beep" sound; if the command "HOLD" is issued in the middle, the hood is opened to this height by default. After the CAN system recognizes that the support rod is in the pulled-up state, the system executes feedback: the voice assistant sends a confirmation voice "The hood is open", the seat or steering wheel vibrates for 1 second, the ambient light goes out, and the display shows "The hood is open".

[0096] It can be understood that in the embodiments of the present application, through voice interaction, the user can conveniently open or close the car hood, which can improve the convenience of using the car; during the process of opening the car hood, multiple confirmations of user instructions can effectively improve the safety of hood control.
