Description

Technical Field

[0001] This application relates to the technical field of automobiles, and in particular to a gesture control method, device, equipment and medium for an automobile engine hood. Background Art

[0002] In recent years, with the development of environmental protection requirements and new energy technologies, more and more automobiles have started using electric energy as the power source. With the popularization of electric vehicles, the front cabin of automobiles has been converted into a storage space more and more frequently, and the frequency of opening and closing the engine hood will also be higher and higher.

[0003] However, limited by safety requirements and restrictions, the automobile engine hood generally cannot be automatically controlled to open and close like an electric tailgate. In related technologies, the opening and closing process of most automobile engine hoods is as follows: The user manually pulls the engine hood switch in the automobile to make the engine hood pop up, and then still needs to manually open the hook of the engine hood in front of the automobile to unlock and open the engine hood. This way of opening the engine hood may cause the following troubles to the car owner: 1) Low opening and closing efficiency: It is necessary to get out of the car and manually operate the opening and closing of the engine hood, which is time-consuming and laborious; 2) More potential safety hazards: On the one hand, the user's hand needs to touch the engine hood. In midsummer, the surface temperature of the engine hood can reach about 80°C, and there is a possibility of scalding the hand. On the other hand, during the process of groping and opening the auxiliary hook, the hand is easily scratched. During the process of lifting or lowering the engine hood, due to the heavy weight of the engine hood, the user's hand and shoulder are easily crushed.

[0055] The embodiments of the present application will be described in detail below. The examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present application, and should not be construed as a limitation to the present application. For the step numbers in the following embodiments, they are only set for the convenience of explanation and illustration, and no limitation is imposed on the order between the steps. The execution order of each step in the embodiments can be adaptively adjusted according to the understanding of those skilled in the art.

[0056] In recent years, with the development of environmental protection requirements and new energy technologies, more and more cars have started to use electric energy as the power source. With the popularization of electric vehicles, the front cabin of cars has been modified into a storage space more and more frequently, and the frequency of opening and closing the hood will also be higher and higher.

[0057] However, limited by safety requirements and restrictions, the car hood generally cannot be automatically controlled to open and close like an electric tailgate. In the related art, the opening and closing process of most car hoods is as follows: The user pulls the hood switch manually in the car to make the hood pop up, and then still needs to manually open the hook of the hood 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 necessary to get out of the car and manually operate the opening and closing of the hood, which is time-consuming and laborious; 2) More potential safety hazards: On the one hand, the user's hand needs to touch the hood. In 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, during the process of groping and opening the auxiliary hook, the hand is easily scratched. During the process of lifting or lowering the hood, due to the heavy weight of the hood, the user's hand and shoulder are easily crushed.

[0058] In view of this, an embodiment of the present application provides a gesture control method for a car hood. The method in the embodiment of the present application is mainly applied in the field of automotive technology. This method can support users to control the opening and closing of the car hood through gestures, so as to achieve contactless opening and closing of the car hood, which is beneficial to improving the convenience and safety of car use.

[0059] First, please refer to Figure 1 , Figure 1 which is a schematic diagram of the implementation environment of a gesture control method for a car hood provided by an embodiment of the present application. Referring to Figure 1 , the main body of this implementation environment mainly includes a user and a car. Among them, this gesture control method for a car hood can be configured in a relevant controller in the car, and the embodiment of the present application does not make specific limitations on this.

[0060] Next, in combination with Figure 1 the shown implementation environment, a gesture control method for a car hood provided by an embodiment of the present application will be introduced and described. Please refer to Figure 2 , Figure 2 which is a schematic diagram of a gesture control method for a car hood provided by an embodiment of the present application. This gesture control method for a car hood includes but is not limited to:

[0061] Step 210: Detect the user's gesture action through a gesture sensing unit;

[0062] In this step, when the user hopes to open the car hood, a gesture action can be made at a specified position of the car. Relevant devices and components in the car can collect and detect the user's gesture action, make corresponding analyses, and thus execute the opening task of the car hood. Specifically, in the embodiment of the present application, the gesture sensing unit is a relevant device that can sense and detect the user's gestures. For example, in some embodiments, it can be divided into an internal and an external gesture sensing unit. The internal gesture sensing unit can be multiple cameras, distributed at various positions inside the car (the purpose of using multiple cameras is to prevent system misjudgment); the external gesture sensing unit is shared with the hood sensing unit and belongs to a type of radar sensing, which can emit / receive radar waves.

[0063] More specifically, the gesture sensing unit detects the user's gesture actions. For the internal gesture sensing unit, it can collect the user's gesture image data through the in-vehicle camera device, match the corresponding gesture commands in the image storage, and then convert the gesture commands into CAN signals to obtain the analysis result of the user's gesture actions. Of course, in some cases, the artificial intelligence image recognition algorithm can also be used to identify and classify the user's gesture image data to obtain the analysis result of the user's gesture actions. For the external gesture sensing unit, it can measure the distance by radar waves, capture the shape, movement time, and movement speed of the user's hand, and match the gesture-related parameters to judge the gesture actions.

[0064] Step 220: When the user's gesture action changes from the first action to the second action, send a first unlocking instruction to the CAN system of the vehicle;

[0065] In this step, the opening instruction of the vehicle hood is set as the switching between two actions. For example, referring to Figure 3 , when the user hopes to open the vehicle hood, their gesture action can change from the state of the arm being held horizontally to the state of the arm being held vertically. At this time, the state of the arm being held horizontally is the first action, and the state of the arm being held vertically is the second action. The gesture sensing unit recognizes that the user's gesture action changes from the first action to the second action and can send a start instruction to the CAN system of the vehicle. In this application, this instruction is recorded as the first unlocking instruction. The first unlocking instruction is used to start and execute the automated control process task of the vehicle hood, and this instruction will be automatically sent to the CAN system of the vehicle for execution after being generated.

[0066] Step 230: The CAN system responds to the first unlocking instruction, controls the hood to open and pop up, and outputs a first inquiry message; the first inquiry message is used to inquire whether the user performs secondary unlocking;

[0067] In this step, when the CAN system of the vehicle receives the first unlocking instruction, it will perform primary unlocking on the vehicle hood according to the first unlocking instruction. Here, since the position where the hood is opened is relatively important for the driving safety of the vehicle, in order to prevent misoperation, generally, a two-level control logic is required to control the opening of the vehicle hood. In the embodiment of this application, the first unlocking instruction is used to achieve primary unlocking. During the primary unlocking process, the vehicle hood will change from the closed state to the state of opening and popping up. Here, the popped-up hood is still restricted by the hook and cannot be directly opened, and the purpose is to prevent misoperation from blocking the driver's line of sight.

[0068] Moreover, in this step, a first inquiry message is also output, which is used to inquire whether the user wants to perform secondary unlocking. In this way, through an interactive method, the unlocking process of the car hood can be confirmed with the user multiple times to prevent the car hood from being accidentally opened, thereby improving the safety of car use. Specifically, in the embodiments of the present application, the content and implementation method of the first inquiry message can be flexibly set according to needs. For example, in some embodiments, the first inquiry message can be output through a display screen / or a voice assistant, and the content of the first inquiry message can be "Are you sure you want to open the hood?" The present application does not make specific restrictions on this.

[0069] Step 240: When the gesture sensing unit recognizes that the user's gesture action is the third action, send a second unlocking instruction to the CAN system of the car;

[0070] In this step, after outputting the first inquiry message, continue to recognize the user's gesture action through the gesture sensing unit. At this time, since the user needs to confirm again whether to open the car hood, the user needs to give an action of a confirmation instruction, which is recorded as the third action in the present application. That is, when the user makes the third action, it can be considered that the user confirms that they need to open the hood. At this time, a second unlocking instruction can be sent to the CAN system of the car to continue the task of opening the hood. In the embodiments of the present application, the form of the third action can be flexibly set according to needs. For example, in some embodiments, referring to Figure 4 , the third gesture can be the gesture of the user raising the thumb. When the gesture sensing unit recognizes this gesture, the second unlocking instruction is triggered.

[0071] It can be understood that in the embodiments of the present application, through multiple confirmation processes, it is possible to effectively avoid the user accidentally triggering the opening and closing process of the car hood and prevent interference with the normal driving of the car.

[0072] Step 250: The CAN system responds to the second unlocking instruction, controls the hook of the hood to open, and drives the strut of the hood to lift to a preset position.

[0073] In the embodiments of the present application, after sending the second unlocking instruction to the CAN system of the car, the CAN system of the car can perform the secondary unlocking task of the hood according to the second unlocking instruction. Here, secondary unlocking means that the hook of the car hood is opened, so that the car can be in a state where the hood can be freely opened. Specifically, the action of opening the hook can be performed by a related motor, and the present application does not limit this. When the hood becomes in a state where it can be freely opened, the hood can be driven to open by a motor. Specifically, in the embodiments of the present application, the driving motor of the hood can be used to control the hood to lift a preset distance and then fix the strut of the hood, thereby completing the opening operation of the hood.

[0074] It should be noted that in the embodiments of the present application, the preset distance for controlling the hood to lift can be flexibly set according to needs, and the present application does not limit this. For example, in some embodiments, during the process of controlling the hood to lift, the user can issue a voice command or other gesture command at any time to inform the vehicle to complete the task of opening the hood. At this time, the hood will stop lifting and hover at the current position due to the action of the strut. Specifically, for example, in some embodiments, the user can issue the command "HOLD" to the voice interaction device, and the hood will default to open to this height. Moreover, in the embodiments of the present application, the system can automatically remember this height and automatically lift to this height and stop during the next or subsequent opening process, that is, use this height as the preset distance for lifting, so as to facilitate users of different heights to use.

[0075] In some embodiments, the CAN system, in response to the first unlocking instruction, controls the hood to open and pop up, including:

[0076] The CAN system, in response to the first unlocking instruction, detects whether the vehicle is in a parked state;

[0077] When the CAN system determines that the vehicle is in a parked state, according to the first unlocking instruction, it controls the hood to open and pop up.

[0078] In the embodiments of the present application, when the CAN system receives the first unlocking instruction, it can detect whether the vehicle is in a parked state. Specifically, since the opening of the vehicle hood may block the driver's line of sight. Therefore, for safety reasons, in the embodiments of the present application, when controlling the automatic opening of the vehicle hood, it is necessary to detect whether the vehicle is in a parked state. Here, the parked state means that the vehicle is currently in a stationary state. In some embodiments, the speed of the vehicle can be detected. When the vehicle speed is 0 or close to 0, it can be considered that the vehicle is in a parked state. Specifically, a comparison threshold for the speed can be set. When the driving speed of the vehicle is less than this comparison threshold, it is considered that the vehicle is in a parked state. In other embodiments, the position information of the vehicle can also be detected. When the position of the vehicle remains unchanged within a certain time interval, it can be considered that the vehicle is in a parked state. It should be noted that the above embodiments are only used for exemplary illustration of detecting whether the vehicle is in a parked state and do not limit the specific implementation of the present application.

[0079] When the CAN system determines that the vehicle is in a parked state, it means that the current opening of the vehicle hood will not affect normal driving, and it can control the hood to open and pop up according to the first unlocking instruction.

[0080] It can be understood that in the embodiments of the present application, during the secondary unlocking process, it is also possible to detect whether the vehicle is in a parked state, so as to determine whether to execute the corresponding instruction. In this way, the safety of vehicle use can be greatly improved.

[0081] In the embodiments of the present application, if the CAN system receives the first unlocking instruction or the second unlocking instruction and the vehicle is not in a parked state, an error message can be displayed on the vehicle's display. The error message can be a text message such as "The vehicle is not currently stopped", and the specific content thereof is not limited in the present application.

[0082] In some embodiments, the method further includes:

[0083] When the user's gesture action changes from the second action to the first action, send a hood closing instruction to the vehicle's CAN system;

[0084] The CAN system responds to the hood closing instruction and controls the hood and the vehicle body to be completely closed.

[0085] The gesture control method for a vehicle hood provided in the embodiments of the present application further includes a scheme for automatically controlling the closing of the hood. Specifically, when the user wishes to close the vehicle hood, an action opposite to opening the hood can be used, that is, changing from the second action to the first action, so as to send a hood closing instruction to the vehicle's CAN system, enabling the CAN system to respond to the hood closing instruction and control the hood and the vehicle body to be completely closed.

[0086] It can be understood that in the embodiments of the present application, the opening and closing instructions for the vehicle hood are exactly opposite, which can effectively reduce the complexity of the instructions and help the user more conveniently achieve intelligent control of the vehicle hood.

[0087] Specifically, in the embodiments of the present application, after the CAN system receives the hood closing instruction, it can detect whether the vehicle is in a parked state. When the vehicle is in a parked state, according to the hood closing instruction, the hood can be controlled to close to a predetermined position, and then after the hood closes to the predetermined position, the hook of the hood can be controlled to act to latch the hood, and at the same time, a primary locking instruction is triggered; this process is the secondary locking process. Then, according to the primary locking instruction, the hood can be controlled to continue closing until it is completely closed with the vehicle body. In this way, the automatic closing control of the vehicle hood is completed.

[0088] Next, a gesture control device for a vehicle hood according to an embodiment of the present application will be described with reference to the accompanying drawings.
