Description

Technical Field

[0001] The present application relates to the field of vehicles, and in particular to a method and device for controlling an engine hood, a vehicle and a storage medium. Background Art

[0002] At present, automobile engines on the market are usually equipped with engine hoods, which can usually prevent dust, static electricity, water, oil, and sound from entering the engine, thereby protecting the safe operation of the engine.

[0003] However, if an abnormal situation occurs during the closing process of the engine hood equipped with an electric suction lock, such as there is a large amount of sand and soil at the connection between the door leaf and the door frame of the engine hood, the electric suction lock will not be able to completely suck the door leaf and the door frame together when the engine hood is closed, causing the engine hood to be in a semi-locked state all the time. The self-priming motor continues to work, but it is still unable to suck the engine hood to a fully locked state, which may cause the self-priming motor to overheat and be damaged. Summary of the invention

[0004] The present application provides a method, device, vehicle and storage medium for controlling an engine hood. The method can timely control an engine hood that cannot be completely closed to open to a fully open state, thereby protecting a motor that controls the closing of the engine hood.

[0005] In a first aspect, a method for controlling an engine hood is provided, the method comprising: in response to an instruction to close the engine hood, controlling the engine hood to close; in the process of controlling the engine hood to close, if the engine hood is not detected to be completely closed within a preset time period, controlling the engine hood to open to a fully open state.

[0006] In the above technical solution, during the process of controlling the closing of the engine hood, if the engine hood is not detected to be completely closed within the preset time, it means that an abnormal situation may occur during the closing process of the engine hood, such as the presence of an obstacle blocking the normal closing of the engine hood. However, at this time, the motor that controls the closing of the engine hood will continue to work, and if the motor continues to work for too long, it may cause overheating and damage to the motor. Therefore, if the engine hood is not detected to be completely closed within the preset time, the engine hood is controlled to open to a fully open state, so that the motor that controls the closing of the engine hood stops working, thereby achieving the purpose of protecting the motor.

[0007] In combination with the first aspect, in certain implementations of the first aspect, the engine hood includes a left-side hood and a right-side hood, and the engine hood is controlled to be closed in response to an instruction to close the engine hood, including: in response to an instruction to close a target hood, controlling an electric suction lock installed on the target hood to perform a locking operation to control the target hood to be closed; wherein the target hood is the left-side hood and / or the right-side hood; the locking operation includes a process of closing the electric suction lock from a fully open position to a half-locked position, and from the half-locked position to a fully locked position.

[0008] In combination with the first aspect and the above-mentioned implementation methods, in certain implementation methods of the first aspect, in the process of controlling the engine hood to close, if the engine hood is not detected to be completely closed within a preset time length, the engine hood is controlled to be opened to a fully open state, including: in the process of the electric suction lock closing from the semi-locked position to the fully locked position, if the target engine hood is not detected to be completely closed within the preset time length, the target engine hood is controlled to be opened to a fully open state.

[0010] According to the above technical solution, when the hood on one side cannot be completely closed during the process of closing the hoods on both sides, the hood on that side is controlled to be fully opened, and the normal hood on the other side is controlled to be fully closed.

[0030] The technical solution in the present application will be described clearly and in detail below in conjunction with the accompanying drawings. In the description of the embodiments of the present application, unless otherwise specified, " / " means or, for example, A / B can mean A or B: "and / or" in the text is only a description of the association relationship of associated objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in the description of the embodiments of the present application, "multiple" means two or more than two.

[0031] In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as suggesting or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0032] At present, automobile engines on the market are usually equipped with engine hoods, which can usually prevent dust, static electricity, water, oil, and sound for the engine, and can protect the safe operation of the engine. Nowadays, some automobile manufacturers have replaced the traditional mechanical lock installed on the engine hood with a more convenient electric suction lock. There is a half-lock switch inside the electric suction lock. The function of this switch is that when the engine hood is closed to the half-lock position, the switch jumps to provide a signal. After the vehicle controller detects the half-lock switch signal jump, it energizes the self-priming motor of the electric suction lock, so that the self-priming motor performs a self-priming action and sucks the engine hood to a fully locked state. When the engine hood is closed, the electric suction lock can completely fasten the lock tongue and the lock buckle through the electric suction action, so that the door leaf and door frame of the engine hood can be completely sucked together, avoiding the embarrassment of the engine hood not being closed tightly, and can also reduce the noise caused by closing the engine hood vigorously.

[0033] In one possible scenario, an abnormal situation occurs during the closing process of the hood equipped with an electric suction lock. For example, there is a large amount of sand at the connection between the door leaf and the door frame of the hood, which causes the electric suction lock to be unable to completely close the door leaf and the door frame when the hood is closed, causing the hood to remain in a semi-locked state. The self-priming motor continues to work, but it is still unable to suck the hood to a fully locked state. At this time, if the self-priming motor is always powered on, it may cause overheating and damage to the self-priming motor.

[0034] In order to solve the above technical problems, an embodiment of the present application provides a method for controlling an engine hood, and the executor of the method is a vehicle, specifically a controller in the vehicle.

[0035] Figure 1 It is a schematic flow chart of a method for controlling an engine hood provided in an embodiment of the present application.

[0036] For example, Figure 1 The method 100 comprises:

[0037] S101, in response to an instruction to close the engine hood, controlling the engine hood to close.

[0038] S102, during the process of controlling the engine hood to close, if the engine hood is not detected to be completely closed within a preset time period, the engine hood is controlled to open to a fully open state.

[0039] An embodiment of the present application provides a method for controlling an engine hood. During the process of controlling the engine hood to close, if the engine hood is not detected to be completely closed within a preset time period, it means that an abnormal situation may occur during the engine hood closing process, such as an obstacle blocking the normal closing of the engine hood. However, at this time, the motor for controlling the closing of the engine hood will continue to work. If the motor continues to work for too long, it may cause overheating and damage to the motor. Therefore, if the engine hood is not detected to be completely closed within the preset time period, the engine hood is controlled to open to a fully open state, so that the motor for controlling the closing of the engine hood stops working, thereby achieving the purpose of protecting the motor.

[0040] Regarding the above S101, it can be understood that the above instruction to close the engine hood may be initiated by the user.

[0041] Optionally, the user can initiate a command to close the engine hood to the engine hood controller through the engine hood switch button or remote control key equipped in the vehicle, the user can also initiate a request to close the engine hood to the engine hood controller through a voice command, or initiate a request to close the engine hood to the engine hood controller through a user terminal bound to the vehicle, gesture recognition, etc. It should be understood that the method of closing the engine hood is not limited in the embodiments of the present application.

[0042] In addition, in order to enrich the car models and meet the user's demand for higher-end, personalized, and ultimate performance car models, the embodiment of the present application also provides a butterfly-opening engine hood, such as Figure 2 In this scenario, the vehicle body domain controller can control the left hood 202 and the right hood 204 to open and close separately, or control the left hood 202 and the right hood 204 to open and close simultaneously. The following will describe the schemes for triggering the instruction to close the engine hood in the above manner.

[0043] In a possible implementation, the center control panel of the vehicle may include multiple buttons for controlling the engine hood, and the user can control the closing or opening of the engine hood by pressing or clicking the multiple buttons for controlling the engine hood. After receiving the user's operation, the center control panel of the vehicle sends the user operation to the body domain controller, and the body domain controller receives the instruction to control the engine hood. Then, when the body domain controller determines that the environment of the vehicle meets the conditions for opening or closing the engine hood, it sends a control instruction to the engine hood controller to control the opening or closing of the engine hood.

[0044] For example, the user can click on the display icon of "Close both hoods" on the center control panel of the vehicle, and the host module of the vehicle sends the user operation to the body domain controller, and the body domain controller receives the instruction to close both hoods. Then, when the body domain controller determines that the environment of the vehicle meets the hood closing conditions, it sends the instruction to close both hoods to the hood controller to control the hoods on both sides to close.

[0045] In a possible implementation, there is a hood logo on the remote control key. When the user wants to open or close the hood, the user can click the hood logo on the remote control key, and the remote control key generates an instruction to control the hood based on the user operation and sends the instruction to the hood controller.

[0046] It is understandable that the vehicle body domain controller can pre-set different user operations corresponding to different commands for controlling the engine hood. For example, if the user presses the engine hood logo on the remote control key once, it corresponds to the command to close the left engine hood; if the user presses the engine hood logo on the remote control key twice in succession, it corresponds to the command to close the left engine hood; if the user continues to press the engine hood logo on the remote control key for a preset time, it corresponds to the command to close the hoods on both sides. Among them, the preset time can be preset, for example, 2 seconds, and this embodiment of the application is not limited to this.

[0047] Exemplarily, when the user presses the hood mark on the remote control key once, the remote control key sends the pressing operation to the body domain controller, which determines that the user wants to control the left hood and determines the state of the left hood saved last time. If the left hood saved last time is in the open state, the body domain controller determines that the user wants to close the left hood at this time, and determines that the instruction to close the left hood is received. When the user presses the hood mark on the remote control key twice in a row, the subsequent body domain controller determines whether the environment in which the vehicle is located meets the conditions for opening or closing the right hood, and sends a control instruction to the hood controller to control the right hood to open or remain closed. The remote control key sends the pressing operation to the body domain controller, which determines that the user wants to control the right hood and determines the state of the right hood saved last time. If the right hood saved last time is in the open state, the body domain controller determines that the user wants to close the right hood at this time, and determines that the instruction to close the right hood is received. When the user continuously presses the hood logo on the remote control key for 2 seconds, the remote control key sends the pressing operation to the body domain controller, which determines that the user wants to control the hoods on both sides and determines the state of the hoods on both sides saved last time. If the hoods on both sides saved last time are in the open state, the body domain controller determines that the user wants to close the hoods on both sides at this time and determines that the instruction to close the hoods on both sides has been received.

[0048] In one possible implementation, after activating the vehicle voice function, the user can make a voice, and the voice collection device in the vehicle head unit (HUT) collects the user's voice to obtain voice data, and sends the voice data to the body domain controller. After receiving the voice data, the body domain controller parses the voice data to obtain a hood control instruction, which is a hood opening instruction or a hood closing instruction. The body domain controller then determines whether the vehicle's environment meets the hood opening or closing conditions, and sends a control instruction to the hood controller to control the hood to open or close. Among them, the voice data is the voice information of the user controlling the hood, and the voice collection device can be a microphone, for example.

[0049] For example, the user sends a voice message "close both hoods". After receiving the voice data, the body domain controller parses the voice data and obtains the instruction to close both hoods. Then the body domain controller sends the instruction to close both hoods to the hood controller to control the closing of both hoods.

[0050] In one possible implementation, the user can click on the control option of the engine hood on the application (APP) of the user terminal for controlling the engine hood, and the user terminal sends the user operation to the body domain controller through the vehicle's telematics box (TBOX), and the body domain controller receives the instruction to control the engine hood. Then the body domain controller determines whether the environment of the vehicle meets the conditions for opening or closing the engine hood, and sends a control instruction to the engine hood controller to control the opening or closing of the engine hood.

[0051] For example, the user can click on the control option of "Close the left hood" on the APP of the user terminal, and the user terminal sends the user operation to the body domain controller through the vehicle's T-BOX. The body domain controller receives the instruction to close the left hood, and then the body domain controller sends the instruction to close the left hood to the hood controller to control the closing of the left hood.

[0052] In one possible implementation, after the Bluetooth of the user terminal establishes a communication connection with the vehicle-mounted Bluetooth, the user operates the Bluetooth on the user terminal, and the user terminal sends the user operation to the body domain controller through the vehicle's low-power Bluetooth (Bluetooth lowenergy, BLE). Then the body domain controller determines whether the vehicle's environment meets the conditions for opening or closing the hood, and sends a control instruction to the hood controller to control the opening or closing of the hood.

[0053] For example, the user can initiate a "close the right side hood" command by operating Bluetooth on the user terminal. The user terminal sends the user operation to the body domain controller through the vehicle's BLE, and then the body domain controller sends the command to close the right side hood to the hood controller to control the closing of the right side hood.

[0054] In one possible implementation, cameras are arranged on the front and both sides of the engine hood. When the user is within a set range of the vehicle, the camera or radar can collect the user's gestures and send the collected user gestures to the body domain controller, so that the body domain controller can obtain instructions for controlling the engine hood based on the user gestures.

[0055] Specifically, the user can pre-set the gesture identifier for controlling the hood, that is, the gesture identifiers corresponding to opening the hood and closing the hood, respectively, and the body domain controller records the gesture identifier. When the user wants to open or close the hood, he can make a pre-set gesture within the reference distance around the vehicle. The camera or radar detects the user gesture and sends the user gesture to the body domain controller. After receiving the user gesture, the body domain controller compares it with the pre-set gesture identifier for controlling the hood. If it is determined that the user's gesture is the same as the gesture identifier corresponding to opening the hood or closing the hood, it is equivalent to the body domain controller receiving an instruction to close or open the hood. In the case where the hood includes a left hood and a right hood, the gesture identifier of the hood also includes a gesture identifier for closing or opening the left hood, a gesture identifier for closing or opening the right hood, and a gesture identifier for closing or opening the hoods on both sides.

[0056] For example, the gesture mark for closing or opening the left hood can be set as raising or lowering the left arm, the gesture mark for closing or opening the right hood can be set as raising or lowering the right arm, and the gesture mark for closing or opening both hoods can be set as raising or lowering both arms. The reference distance can also be preset, for example, it can be set to 5 meters, which is not limited in the embodiments of the present application.

[0057] For example, when the user lowers his left arm within 5 meters in front of the vehicle, the camera or radar detects the user's operation and sends the user gesture to the body domain controller. The body domain controller compares the user gesture with the preset hood control gesture identifier to determine that the instruction to close the left engine hood has been received. When the user lowers his right arm within 5 meters in front of the vehicle, the body domain controller determines that the instruction to close the right engine hood has been received. When the user lowers both arms within 5 meters in front of the vehicle, the body domain controller determines that the instruction to close the engine hoods on both sides has been received.

[0058] The above method initiates the command to control the closing of the engine hood in a variety of ways, making the vehicle use process more intelligent and improving the convenience of user use.

[0059] It should be understood that when the engine hood controller receives the instruction to close the engine hood, it can control the following Figure 2 The electric suction lock installed on the engine hood shown is used to control the closing of the engine hood. Specifically, the closing of the left hood can be controlled by controlling the left hood lock 201, the closing of the right hood can be controlled by controlling the right hood lock 203, and the closing of the left and right hoods can be controlled simultaneously by the left hood lock 201 and the right hood lock 203.

[0060] In one possible implementation, the engine hood includes a left-side hood and a right-side hood, and the engine hood is controlled to be closed in response to an instruction to close the engine hood, including: in response to an instruction to close a target hood, controlling an electric suction lock installed on the target hood to perform a locking operation to control the target hood to be closed; wherein the target hood is the left-side hood and / or the right-side hood; the locking operation includes a process of closing the electric suction lock from a fully open position to a half-locked position, and from the half-locked position to a fully locked position.

[0061] It is understandable that the engine hood may include a left hood and a right hood, and the engine hood controller may control the left hood to be closed through the electric suction lock installed on the left hood, and may also control the right hood to be closed through the electric suction lock installed on the right hood, and may also control the left hood to be closed and the right hood to be closed at the same time through the electric suction lock installed on the left hood and the electric suction lock installed on the right hood. Therefore, the target hood in the embodiment of the present application may be the left hood, the right hood, or both the left hood and the right hood.

[0062] Exemplarily, when the target hood is the left hood, in response to the instruction to close the left hood, the electric suction lock installed on the left hood is controlled to perform a locking operation to control the left hood to be closed. When the target hood is the right hood, in response to the instruction to close the right hood, the electric suction lock installed on the right hood is controlled to perform a locking operation to control the right hood to be closed. When the target hoods are the left hood and the right hood, in response to the instruction to close the left hood and the right hood, the electric suction locks installed on the left hood and the right hood are controlled to perform a locking operation to control the left hood and the right hood to be closed.

[0063] It should be understood that the process of closing an engine hood equipped with an electric suction lock is usually to control the electric suction lock on the engine hood to close from the fully open position to the half-locked position when the command to close the engine hood is received, and then control the self-priming motor to close the electric suction lock from the half-locked position to the fully locked position, so that the engine hood is completely closed.

[0064] Specifically, the process of closing the hood is as follows: after the hood controller receives the instruction to close the hood, when it determines that the current vehicle state meets the closing conditions, it drives the buzzer of the electric suction lock on both sides of the hood or the left side of the hood or the right side of the hood to sound once, and after a delay of 0.5 seconds, drives the electric support rods of the hoods on both sides or the left side of the hood or the right side of the hood to reverse, and stops driving the electric support rods of the hoods on both sides or the left side of the hood or the right side of the hood after the electric suction locks of the hoods on both sides or the left side of the hood or the right side of the hood reach the half-locked position, and then drives the electric suction locks of the hoods on both sides or the left side of the hood or the right side of the hood to self-suck to the full-locked position, so that the hood is in a completely closed state.

[0065] Regarding the above S102, it can be understood that when the hood is in a fully closed state, the electric suction lock on the hood is in a fully locked position. When the hood is in a fully opened state, the electric suction lock on the hood is in a fully open position. If the hood controller does not detect that the hood is fully closed within a preset time, the electric suction lock on the hood may be in a half-locked position.

[0066] It is also understandable that, in the process of controlling the closing of the engine hood, an obstacle may block the normal closing of the engine hood, which may cause the engine hood controller to be unable to detect that the engine hood is completely closed within a preset time.

[0067] For example, for a hood equipped with an electric suction lock, if there is a large amount of sand at the connection between the door leaf and the door frame of the hood, it will usually cause the electric suction lock to be unable to close from the half-locked position to the fully locked position, which will cause the hood to be unable to be completely closed. At this time, if the self-priming motor continues to work, it may cause overheating and damage to the self-priming motor. Therefore, in the embodiment of the present application, when it is determined that the hood cannot be completely closed, the hood is controlled to open to the fully open state, which can stop the self-priming motor from working, thereby protecting the self-priming motor.

[0068] In one possible implementation, during the process of controlling the engine hood to close, if the engine hood is not detected to be completely closed within a preset time period, the engine hood is controlled to open to a fully open state, including: during the process of the electric suction lock closing from the half-lock position to the full-lock position, if the target engine hood is not detected to be completely closed within the preset time period, the target engine hood is controlled to open to a fully open state.

[0069] Specifically, during the closing process, the electric suction lock will send a signal to the engine hood controller each time it reaches a closed position, so that the engine hood controller can timely understand the working status of the electric suction lock. Exemplarily, after the electric suction lock reaches the half-locked position, the electric suction lock will send a half-locked signal to the engine hood controller; after the electric suction lock reaches the full-locked position, the electric suction lock will also send a full-locked signal to the engine hood controller to indicate that the engine hood is completely closed. The time taken for the electric suction lock to go from the half-locked position to the full-locked position, that is, the motor self-priming, is relatively short, about 2 seconds. Therefore, if during the process of the electric suction lock closing from the half-locked position to the full-locked position, the engine hood controller determines that it has not received a full-locked signal within a preset time after receiving the half-locked signal, it controls the engine hood to open to the fully open state.

[0070] It is understandable that the above preset time can be set according to the actual situation, and is generally set according to the time required for the electric suction lock to close from the half-locked position to the fully locked position. For example, if the time required for a certain self-priming lock to close from the half-locked position to the fully locked position is 2 seconds, the preset time is set to 4 seconds. If the engine hood is still not completely closed within 4 seconds, it means that the electric suction lock is abnormal at this time, and the engine hood is controlled to open to the fully open state.

[0071] For example, as shown in FIG3(a), the preset time is set to 4 seconds. When the target hood is the left hood, during the process of the electric suction lock installed on the left hood closing from the half-locked position to the fully locked position, if the hood controller does not detect that the left hood is completely closed within 4 seconds, the left hood is controlled to open to the fully open state.

[0072] When the target hood is the right hood, during the process of the electric lock installed on the right hood closing from the half-locked position to the fully locked position, if the engine hood controller does not detect that the right hood is completely closed within 4 seconds, the right hood is controlled to open to the fully open state.

[0073] It is understandable that the engine hood controller can also control the closing of the left and right hoods at the same time.

[0074] For example, as shown in FIG3(b), when the target hoods are the left hood and the right hood, during the process of the electric suction lock installed on the left hood and the right hood closing from the half-lock position to the full-lock position, if the hood controller does not detect that the left hood is completely closed within the preset time, and does not detect that the right hood is completely closed, then the left hood and the right hood are controlled to open to the fully open state. Conversely, if the hood controller detects that the left hood is completely closed within the preset time, and detects that the right hood is completely closed, then the left hood and the right hood are controlled to be in the fully closed state.

[0075] When the target hoods are the left hood and the right hood, the method also includes: in the process of closing the electric suction locks installed on the left hood and the right hood from the semi-locked position to the fully locked position, if the left hood is not detected to be completely closed within the preset time length, and the right hood is detected to be completely closed, then the left hood is controlled to be opened to a fully open state, and the right hood is controlled to be in a fully closed state; in the process of closing the electric suction locks installed on the left hood and the right hood from the semi-locked position to the fully locked position, if the right hood is not detected to be completely closed within the preset time length, and the left hood is detected to be completely closed, then the right hood is controlled to be opened to a fully open state, and the left hood is controlled to be in a fully closed state.

[0076] In the above method, when the hood on one side cannot be completely closed during the process of closing the hoods on both sides, the hood on that side is controlled to be fully opened, and the normal hood on the other side is controlled to be fully closed. Different operations are performed according to the different states of the hoods on both sides, so that the user can more intuitively see which hood on which side has a fault, so that the user can promptly identify the faulty hood.

[0077] It is understandable that during the process of the electric suction lock installed on the hood closing from the half-locked position to the fully locked position, if the hood controller does not detect that the hood is completely closed within the preset time, it may be because there is an obstacle at the connection between the door leaf and the door frame of the hood, and the user can generally manually clear the obstacle. Therefore, if the hood controller does not detect that the hood is completely closed within the preset time, it can control the hood to open in the reverse direction to the fully open state and remind the user to check the status of the hood.

[0078] In a possible implementation, the method further includes: if the engine hood is not detected to be completely closed within the preset time period, reminding the user in a preset reminder manner.

[0079] It is understandable that when the hood controller does not detect that the hood is completely closed within a preset time, the hood controller can first determine the reason why the hood cannot be completely closed, and then determine a solution based on the reason, and can also notify the user of the solution when reminding the user.

[0080] For example, if the hood controller does not detect that the hood is completely closed within a preset time, it may be because there is an obstacle at the connection between the door leaf and the door frame of the hood. Therefore, the user can be reminded to clear the obstacle in time in a preset reminder manner.

[0081] It is understandable that the prerequisite for reminding the user through the above reminder method may be that the vehicle's power mode is turned on and the vehicle is powered on.

[0082] Optionally, the preset reminder method can be an alarm sound from a buzzer installed on the electric suction lock, or a voice reminder, or flashing of vehicle lights, or display of fault reminder information through the vehicle's dashboard or vehicle display screen or a user terminal display screen bound to the vehicle, etc. The embodiments of the present application do not limit the possible reminder methods.

[0083] It is understandable that if the hood controller does not detect that the hood is completely closed within the preset time, it can send reminder information to the user in the above preset reminder mode at the same time, or send reminder information to the user in sequence according to the priority order of the preset reminder modes until the hood controller detects that the hood is completely closed. Among them, the priority order of the reminder mode can be that the priority of the buzzer emitting an alarm is higher than the priority of the voice reminder, the priority of the voice reminder is higher than the priority of the display screen displaying the reminder information, and the priority of the display screen displaying the reminder information is higher than the priority of the flashing lights.

[0084] In a possible implementation, if the hood controller does not detect that the hood is completely closed within a preset time period, a reminder message may be sent to the user in the above-mentioned preset reminder manner.

[0085] Exemplarily, when the above-mentioned preset reminder method is that the buzzer sounds an alarm, if the hood controller does not detect that the hood is completely closed within the preset time, the buzzer installed on the electric suction lock can be controlled to continue to sound an alarm to remind the user to check the status of the hood until the hood controller detects that the hood is completely closed.

[0086] In another possible implementation, if the hood controller does not detect that the hood is completely closed within a preset time period, reminder messages may be sent to the user in sequence according to the priority order of the preset reminder methods.

[0087] For example, if the hood controller does not detect that the hood is completely closed within a preset time, it can first control the buzzer installed on the electric suction lock to continuously sound an alarm to remind the user to check the status of the hood.

[0088] If the duration of the alarm sounded by the buzzer installed on the electric suction lock exceeds the preset first reminder duration, and the hood controller still has not detected that the hood is completely closed, the hood controller can initiate a first request message to the body domain controller, requesting the body domain controller to control the speaker to issue a voice reminder message until the hood controller detects that the hood is completely closed.

[0089] If the duration of the speaker sending out the voice reminder message exceeds the preset second reminder duration, and the hood controller still has not detected that the hood is completely closed, the hood controller initiates a second request message to the body domain controller, requesting the body domain controller to display the reminder message of the hood failure on the central control screen, and at the same time synchronously send the reminder message to the user terminal bound to the vehicle.

[0090] If the reminder message is displayed on the display screen for longer than the preset third reminder time, and the hood controller still has not detected that the hood is completely closed, the hood controller initiates a third request message to the body domain controller, requesting the body domain controller to control the vehicle's headlights to flash alternately to remind the user to check the status of the hood until the hood controller detects that the hood is completely closed.

[0091] It is understandable that the first reminder duration, the second reminder duration and the third reminder duration can be set to the same duration, or corresponding durations can be set according to the first request information, the second request information and the third request information. The first request information is used to request the body domain controller to control the speaker to issue a voice reminder message, the second request information is used to request the body domain controller to display the reminder message of the engine hood failure on the central control screen, and simultaneously send the reminder message to the user terminal bound to the vehicle, and the third request information is used to request the body domain controller to control the vehicle's headlights to flash alternately to remind the user to check the status of the engine hood.

[0092] In the above method, if the hood controller fails to detect that the hood is completely closed within the preset time, it will send a reminder message to the user in a preset reminder manner, which can facilitate the user to timely troubleshoot the hood failure. If the duration of the buzzer installed on the electric suction lock to emit an alarm exceeds the preset reminder duration, and the hood controller still fails to detect that the hood is completely closed, the hood controller will send a reminder message to the user in other reminder methods, which can prevent the buzzer from continuously sounding an alarm and causing discomfort to other people around the vehicle. Reminding the user in other reminder methods can also let the user know as soon as possible that the hood cannot be closed.

[0093] In another possible implementation, when the hood controller fails to detect that the hood is completely closed within a preset time, it can first control the buzzer installed on the electric suction lock to continuously sound an alarm to remind the user to check the status of the hood until the hood controller detects that the hood is completely closed. If the duration of the buzzer installed on the electric suction lock sounding the alarm exceeds the preset reminder time, such as 30 seconds, and the hood controller still fails to detect that the hood is completely closed, the hood controller can also remind the user simultaneously by voice reminder, displaying reminder information on the display screen, and flashing the lights, until the hood controller detects that the hood is completely closed.

[0094] For example, if the hood controller does not detect that the hood is completely closed within a preset time, it can first control the buzzer installed on the electric suction lock to continuously sound an alarm to remind the user to check the status of the hood. If the duration of the alarm sounded by the buzzer installed on the electric suction lock exceeds the preset first reminder time, and the hood controller still does not detect that the hood is completely closed, the hood controller can simultaneously initiate a request message to the body domain controller, requesting the body domain controller to control the speaker to issue a voice reminder message, requesting the body domain controller to display a reminder message of the hood failure on the central control screen, and simultaneously sending the reminder message to the user terminal bound to the vehicle, requesting the body domain controller to control the vehicle's headlights to flash alternately to remind the user to check the status of the hood.

[0095] In one possible implementation, the engine hood includes a left-side hood and a right-side hood. If the engine hood is not detected to be completely closed within the preset time, the user is reminded in a preset reminder manner, including: if the left-side hood is not detected to be completely closed within the preset time, the user is reminded by flashing the left-side headlight of the vehicle; if the right-side hood is not detected to be completely closed within the preset time, the user is reminded by flashing the right-side headlight of the vehicle; if the left-side hood and the right-side hood are not detected to be completely closed within the preset time, the user is reminded by flashing the left-side headlight and the right-side headlight of the vehicle.

[0096] For example, when the hood controller receives an instruction to close the left hood, it controls the left hood to close. If the hood controller does not detect that the left hood is completely closed within a preset time, it reminds the user by flashing the lights in a preset manner. The hood controller sends a request message to the body domain controller, requesting the body domain controller to control the left headlights of the vehicle to flash alternately to remind the user to check the status of the hood, until the hood controller detects that the left hood is completely closed.

[0097] When the hood controller receives an instruction to close the right hood, it controls the right hood to close. If the hood controller does not detect that the right hood is completely closed within the preset time, it reminds the user by flashing the lights in a preset manner. The hood controller sends a request message to the body domain controller, requesting the body domain controller to control the right headlights of the vehicle to flash alternately to remind the user to check the status of the hood, until the hood controller detects that the right hood is completely closed.

[0098] When the hood controller receives an instruction to close the left and right hoods at the same time, it controls the left and right hoods to close. If the hood controller does not detect that the left and right hoods are completely closed within the preset time, it reminds the user by flashing the lights in a preset manner. The hood controller sends a request message to the body domain controller, requesting the body domain controller to control the left and right headlights of the vehicle to flash alternately at the same time to remind the user to check the status of the hood, until the hood controller detects that the left and right hoods are completely closed.

[0099] It is understandable that even if the user is not at the location of the vehicle, the flashing of the vehicle lights can allow other people around the vehicle to notice the abnormality of the vehicle.

[0100] The above method, when it is determined that the engine hood cannot be completely closed, reminds the user in a preset reminder mode, which can facilitate the user to timely troubleshoot the engine hood failure. Different operations are performed according to the different states of the hoods on both sides, and the lights on the side where the hood fails are flashed, which can not only remind the user that the hood is faulty, but also allow the user to more intuitively identify the faulty hood.
