Description

TECHNICAL FIELD

[0001] The present application relates to the field of vehicle safety, and more particularly, to a vehicle engine compartment safety control method and device, a vehicle and a storage medium. BACKGROUND

[0002] At present, in the vehicle industry, with the continuous upgrading and reform of vehicle production technology, the structure of the vehicle has also gradually changed.

[0003] In one possible implementation, the engine cover of the vehicle evolves from the original one-piece structure to a two-piece structure, i.e., the engine cover is divided into a left cover (referred to as "left cover") and a right cover (referred to as "right cover"). Among them, the left cover corresponds to the left side position of the engine compartment, and the right cover corresponds to the right side position of the engine compartment. The left cover and the right cover can be independently opened and closed without affecting each other.

[0004] Based on the structure of the engine cover described above, how to ensure the safety of the engine compartment of the vehicle and reasonably control the opening or closing of the engine cover has become a problem to be solved. SUMMARY

[0005] The present application provides a vehicle engine compartment safety control method, device, vehicle and storage medium. The method can accurately determine the target position of the engine compartment where the abnormality occurs based on the environmental parameters in the engine compartment of the vehicle when the engine cover of the vehicle is divided into a left cover and a right cover. And further intelligently and flexibly control the opening of the cover at the target position, thereby ensuring the safety of the vehicle.

[0006] In a first aspect, a vehicle engine compartment safety control method is provided. The method includes: in a case where the state of a vehicle is in a powered-on state, obtaining an environmental parameter of an engine compartment of the vehicle, the environmental parameter being used to indicate an in-cabin environmental state of the engine compartment; in a case where the environmental parameter meets a preset condition, determining a target position where an abnormality occurs in the engine compartment, the target position including a left side position and a right side position of the engine compartment; according to the target position and the environmental parameter, triggering a target prompt information, the target prompt information being used to prompt that an abnormality occurs at the target position of the engine compartment; in a case where the vehicle speed of the vehicle is less than or equal to a preset vehicle speed, controlling a target cover corresponding to the target position to open, the target cover including a left cover corresponding to the left side position and a right cover corresponding to the right side position.

[0007] In the above technical solution, when the vehicle is in a powered-on state, in order to ensure and monitor the safety of the vehicle, the application proposes a vehicle engine compartment safety control method. Specifically, the environmental parameters of the engine compartment can be obtained, wherein the environmental parameters can represent the cabin environmental state of the engine compartment. Further, by comparing the environmental parameters with the preset conditions, if the environmental parameters meet the preset conditions, it is determined that the vehicle engine compartment is abnormal, and the target position of the abnormality is confirmed. The target position can be the left position or the right position of the engine compartment. Then, by the target position and the environmental parameters, the target prompt information is triggered to remind the user of the abnormality of the target position. Finally, when the vehicle speed is less than or equal to the preset vehicle speed, the application can further control the target hood corresponding to the target position to open. The target hood includes a left hood corresponding to the left position and a right hood corresponding to the right position.

[0008] The above method for monitoring the safety of the engine compartment through environmental parameters is simple, accurate and efficient. When the vehicle is abnormal, the user can be reminded to timely alert and handle the abnormality of the target position, thereby ensuring the safety of the user when the user is riding the vehicle. Finally, based on the correspondence between the target hood and the target position, the application can flexibly control the target hood corresponding to the target position to open when the vehicle speed is low. On the one hand, the left hood and the right hood can be flexibly opened without interfering with each other. On the other hand, the target hood can be opened to achieve intelligent handling of the abnormality in the vehicle.

[0009] In combination with the first aspect, in some possible implementation manners, the environmental parameters include at least one of smoke concentration, temperature, and noise decibel. After obtaining the environmental parameters of the engine compartment of the vehicle, the method further includes: determining that the environmental parameters meet the preset conditions when the smoke concentration is greater than a preset concentration, and / or the temperature is greater than a preset temperature, and / or the noise decibel is greater than a preset decibel; determining that the environmental parameters do not meet the preset conditions when the smoke concentration is less than or equal to the preset concentration, and the temperature is less than or equal to the preset temperature, and the noise decibel is less than or equal to the preset decibel.

[0010] In the technical solution, according to the state of the engine compartment during operation, the environmental parameter includes at least one of smoke concentration, temperature and noise decibel. When the environmental parameter meets the preset condition, specifically, when the smoke concentration is greater than the preset concentration, and / or, the temperature is greater than the preset temperature, and / or, the noise decibel is greater than the preset decibel, it is determined that the environmental parameter meets the preset condition. On the contrary, when the smoke concentration is less than or equal to the preset concentration, and / or, the temperature is less than or equal to the preset temperature, and / or, the noise decibel is less than or equal to the preset decibel, it is determined that the environmental parameter does not meet the preset condition. Through the judgment of the smoke concentration, temperature and noise decibel, the problem of fire and abnormal operation of components in the engine compartment can be avoided, and the safety of the engine compartment can be effectively ensured.

[0011] In combination with the first aspect and the above implementation manners, in some possible implementation manners, the environmental parameter includes a first environmental parameter corresponding to the left side position and a second environmental parameter corresponding to the right side position, the first environmental parameter includes at least one of a first smoke concentration, a first temperature and a first noise decibel, the second environmental parameter includes at least one of a second smoke concentration, a second temperature and a second noise decibel, and in the case that the smoke concentration is greater than the preset concentration, and / or, the temperature is greater than the preset temperature, and / or, the noise decibel is greater than the preset decibel, it is determined that the environmental parameter meets the preset condition, including at least one of the following: in the case that the first smoke concentration is greater than the preset concentration, and / or, the first temperature is greater than the preset temperature, and / or, the first noise decibel is greater than the preset decibel, it is determined that the first environmental parameter meets the preset condition; in the case that the second smoke concentration is greater than the preset concentration, and / or, the second temperature is greater than the preset temperature, and / or, the second noise decibel is greater than the preset decibel, it is determined that the second environmental parameter meets the preset condition.

[0012] In the technical solution, the hood of the engine is divided into a left hood and a right hood, and the first environmental parameter of the left side position corresponding to the left hood and the second environmental parameter of the right side position corresponding to the right hood can be monitored separately. Based on the above process, when the environmental parameter meets the preset condition, there are two scenarios: in the case that the first smoke concentration is greater than the preset concentration, and / or, the first temperature is greater than the preset temperature, and / or, the first noise decibel is greater than the preset decibel, it is determined that the first environmental parameter meets the preset condition; in the case that the second smoke concentration is greater than the preset concentration, and / or, the second temperature is greater than the preset temperature, and / or, the second noise decibel is greater than the preset decibel, it is determined that the second environmental parameter meets the preset condition. The above monitoring of the environmental parameters of different sides of the engine compartment can realize the subsequent separate control of the left hood and the right hood.

[0013] With reference to the first aspect and the above implementation manners, in some possible implementation manners, the target position where the engine compartment has the abnormality is determined in the case where the environment parameter meets the preset condition, including: in the case where the first environment parameter meets the preset condition, the left position is determined as the target position; in the case where the second environment parameter meets the preset condition, the right position is determined as the target position; and in the case where the first environment parameter meets the preset condition and the second environment parameter meets the preset condition, the left position and the right position are determined as the target position.

[0014] In the above technical solution, based on the separate monitoring processes of the first environment parameter and the second environment parameter, the target position is determined in three scenarios. In the first scenario, the left position is determined as the target position in the case where the first environment parameter meets the preset condition; in the second scenario, the right position is determined as the target position in the case where the second environment parameter meets the preset condition; and in the third scenario, the left position and the right position are determined as the target position in the case where the first environment parameter and the second environment parameter both meet the preset condition. The above process realizes the determination of different target positions according to the types of the environment parameters, and ensures the accuracy of the determination of the target position.

[0015] With reference to the first aspect and the above implementation manners, in some possible implementation manners, the target prompt information is triggered according to the target position and the environment parameter, including: the target prompt information is generated according to the target position and the environment parameter; the display device of the vehicle is controlled to display the target prompt information, and the audio playing device of the vehicle is controlled to play the target prompt information.

[0016] In the above technical solution, when the vehicle has an abnormality, in order to timely remind the user, the application provides a triggering process of the target prompt information. Specifically, the vehicle can generate the target prompt information according to the target position and the environment parameter. Then the display device is further controlled to display the target prompt information, and the audio playing device is further controlled to play the target prompt information. Thus, in the case where the engine compartment has an abnormality, the user is quickly and diversely reminded in a voice reminding and text reminding dual reminding manner, so that the user can timely pay attention to and handle the abnormality. Thus, the life safety of the user and the safety of the vehicle are ensured.

[0017] In some possible implementation manners, in combination with the first aspect and the foregoing implementation manners, the environment parameter includes at least one of a temperature and a noise decibel, and the control of the target hood opening in the case where the vehicle speed is less than or equal to the preset vehicle speed includes any of the following: in the case where the vehicle speed is less than or equal to the preset vehicle speed, the target hood is controlled to open in response to an opening instruction of the target hood, and the trigger manner of the opening instruction includes any of voice control, a click operation, and gesture adjustment operation; or in the case where the vehicle speed is less than or equal to the preset vehicle speed, the target hood is controlled to open.

[0018] In the foregoing technical solution, when the target hood is opened, the application can provide two opening scenarios. The first scenario is a manual opening scenario, in which the user needs to manually control the opening process of the target hood. Specifically, the user can control the target hood to open in multiple opening manners such as voice control (for example, a voice of "opening the target hood"), a click operation (for example, selecting an "opening" control of the target hood by a click operation), and gesture adjustment operation (for example, making a gesture corresponding to opening the target hood).

[0019] The second scenario is an automatic opening scenario, in which the user does not need to participate. As long as the vehicle detects that the vehicle speed is less than or equal to the preset vehicle speed, the target hood is automatically triggered to open.

[0020] The foregoing two opening scenarios ensure that the opening manner of the target hood is flexible and various, and improve the opening efficiency of the target hood.

[0021] In some possible implementation manners, in combination with the first aspect and the foregoing implementation manners, the environment parameter includes at least one of a smoke concentration and a temperature, and after the target prompt information is triggered according to the target position and the environment parameter, the method further includes at least one of the following: in the case where the environment parameter is the smoke concentration, the fire extinguishing system in the engine compartment is controlled to open to reduce the smoke concentration corresponding to the target position; or in the case where the environment parameter is the temperature, the cooling system in the engine compartment is controlled to open to reduce the temperature corresponding to the target position.

[0022] In the foregoing technical solution, the smoke concentration is usually an environment parameter when a fire accident occurs in the vehicle. In order to timely handle the exception, the application can also intelligently open the fire extinguishing system in the engine compartment to perform fire extinguishing processing when the smoke concentration in the vehicle is high, so as to reduce the smoke concentration in the engine compartment; or the cooling system in the engine compartment can also be opened to reduce the temperature when the temperature in the engine compartment is high. The foregoing process ensures that the exception of the vehicle is automatically handled in time when the exception occurs in the vehicle, avoids further aggravation and spread of the exception, and ensures the safety of the vehicle.

[0023] In summary, in order to ensure and monitor the safety of the vehicle when the vehicle is in the power-on state, the application provides a vehicle engine compartment safety control method. Specifically, the environmental parameters of the engine compartment can be obtained, wherein the environmental parameters can represent the cabin environmental state of the engine compartment. Further, by comparing the environmental parameters with the preset conditions, if the environmental parameters meet the preset conditions, it is determined that the vehicle engine compartment is abnormal, and the target position of the abnormality is confirmed. The target position can be the left position and the right position of the engine compartment. Then, through the target position and the environmental parameters, the target prompt information is triggered to remind the user of the abnormality of the target position. Finally, when the vehicle speed is less than or equal to the preset vehicle speed, the application can further control the target hood corresponding to the target position to open. The target hood includes a left hood corresponding to the left position and a right hood corresponding to the right position.

[0024] The above method for monitoring the safety of the engine compartment through environmental parameters is simple, accurate and efficient. When the vehicle is abnormal, the user can be reminded to timely alert and handle the abnormality of the target position, thereby ensuring the safety of the user when the user is riding the vehicle. Finally, based on the correspondence between the target hood and the target position, the application can flexibly control the target hood corresponding to the target position to open when the vehicle speed is low. On the one hand, the left hood and the right hood can be flexibly opened without interfering with each other. On the other hand, opening the target hood can also achieve the effect of intelligently handling the abnormality in the vehicle.

[0025] According to the state of the engine compartment during operation, the environmental parameters of the application include at least one of smoke concentration, temperature and noise decibel. When the environmental parameters meet the preset conditions, specifically when the smoke concentration is greater than the preset concentration, and / or the temperature is greater than the preset temperature, and / or the noise decibel is greater than the preset decibel, it is determined that the environmental parameters meet the preset conditions. Conversely, when the smoke concentration is less than or equal to the preset concentration, and / or the temperature is less than or equal to the preset temperature, and / or the noise decibel is less than or equal to the preset decibel, it is determined that the environmental parameters do not meet the preset conditions. By judging the smoke concentration, temperature and noise decibel, the problems of fire and abnormal operation of components in the engine compartment can be avoided, thereby effectively ensuring the safety of the engine compartment.

[0026] The engine-based engine cover is divided into a left engine cover and a right engine cover, and the application can separately monitor the first environmental parameter of the left side position corresponding to the left engine cover and the second environmental parameter of the right side position corresponding to the right engine cover. Based on the above process, when it is judged that the environmental parameter meets the preset condition, two scenarios can be divided: in the case that the first smoke concentration is greater than the preset concentration, and / or the first temperature is greater than the preset temperature, and / or the first noise decibel is greater than the preset decibel, it is determined that the first environmental parameter meets the preset condition; in the case that the second smoke concentration is greater than the preset concentration, and / or the second temperature is greater than the preset temperature, and / or the second noise decibel is greater than the preset decibel, it is determined that the second environmental parameter meets the preset condition. The above monitoring of the environmental parameters of different sides of the engine compartment can achieve the effect of separately controlling the left engine cover and the right engine cover.

[0027] Based on the above separate monitoring process of the first environmental parameter and the second environmental parameter, there are also three scenarios when determining the target position. The first scenario is to determine the left side position as the target position when the first environmental parameter meets the preset condition; the second scenario is to determine the right side position as the target position when the second environmental parameter meets the preset condition; and the third scenario is to determine the left side position and the right side position as the target position when both the first environmental parameter and the second environmental parameter meet the preset condition. The above process realizes the determination of different target positions according to the type of environmental parameters, ensuring the accuracy of target position determination.

[0028] When it is determined that the vehicle has an abnormality, in order to timely remind the user, the application provides a triggering process of target prompt information. Specifically, the vehicle can generate target prompt information according to the target position and the environmental parameter. Then further control the display device to display the target prompt information, and the audio playing device to broadcast the target prompt information. Thus, when the engine compartment has an abnormality, the application realizes the way of double reminding based on voice and text, quickly and diversely reminding the user, so that the user can timely pay attention to and handle the abnormality. Thus, the safety of the user and the vehicle is ensured.

[0029] When the target engine cover is opened, the application can provide two opening scenarios. The first scenario is a manual opening scenario, in which the user needs to manually control the opening process of the target engine cover. Specifically, the user can control the target engine cover to open through various opening methods such as voice control (for example, the voice of "opening the target engine cover"), click operation (for example, selecting the "open" control of the target engine cover through click operation), gesture adjustment operation (for example, making a gesture to open the target engine cover), etc.

[0030] The second scenario is an automatic opening scenario, in which the user does not need to participate. As long as the vehicle detects that the vehicle speed is less than or equal to the preset vehicle speed, the target engine cover is automatically triggered to open automatically.

[0031] The two opening scenarios ensure that the target hood can be opened in a flexible and diverse manner, and the opening efficiency of the target hood is improved.

[0032] The smoke concentration is usually an environmental parameter when a vehicle fire accident occurs. In order to handle the abnormality in time, the engine compartment fire extinguishing system can be opened to perform fire extinguishing treatment when the smoke concentration in the vehicle is high, so as to reduce the smoke concentration in the engine compartment. Alternatively, the cooling system in the engine compartment can be opened to reduce the temperature in the engine compartment when the temperature in the engine compartment is high. The above process ensures that the abnormality of the vehicle is automatically handled in time when the vehicle is abnormal, avoids further aggravation and spread of the abnormality, and ensures the safety of the vehicle.

[0033] In a second aspect, a vehicle engine compartment safety control apparatus is provided. The apparatus includes: an acquisition module configured to acquire an environmental parameter of an engine compartment of a vehicle when a state of the vehicle is in a powered-on state, the environmental parameter being used to indicate an in-cabin environmental state of the engine compartment; a first determination module configured to determine a target position where an abnormality occurs in the engine compartment when the environmental parameter satisfies a preset condition, the target position including a left side position and a right side position of the engine compartment; a triggering module configured to trigger a target prompt information according to the target position and the environmental parameter, the target prompt information being used to prompt that the target position of the engine compartment has an abnormality; and a control module configured to control a target hood to open when a vehicle speed of the vehicle is less than or equal to a preset vehicle speed, the target hood including a left hood corresponding to the left side position and a right hood corresponding to the right side position.

[0034] In combination with the second aspect, in some possible implementation manners, the environmental parameter includes at least one of a smoke concentration, a temperature, and a noise decibel. After the environmental parameter of the engine compartment of the vehicle is acquired, the apparatus further includes: a second determination module configured to determine that the environmental parameter satisfies the preset condition when the smoke concentration is greater than a preset concentration, and / or the temperature is greater than a preset temperature, and / or the noise decibel is greater than a preset decibel; and determine that the environmental parameter does not satisfy the preset condition when the smoke concentration is less than or equal to the preset concentration, the temperature is less than or equal to the preset temperature, and the noise decibel is less than or equal to the preset decibel.

[0048] The technical solutions in this application will be clearly and thoroughly described below with reference to the accompanying drawings. In the description of the embodiments of this application, unless otherwise stated, " / " means "or," for example, A / B can mean A or B. "And / or" in the text is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Furthermore, in the description of the embodiments of this application, "multiple" refers to two or more than two.

[0049] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as implying or suggesting 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 that feature.

[0050] Figure 1 This is a schematic diagram of the structure of a vehicle engine hood provided in an embodiment of this application.

[0051] For example, such as Figure 1 As shown, an engine compartment is typically found in vehicles 101. The engine compartment generally includes the engine, battery, coolant reservoir, relay box, brake booster pump, fluid reservoir, and other components related to the operation of the vehicle 101.

[0052] Correspondingly, the component used to cover the engine compartment is called an "engine hood" (also known as an engine cover, hereinafter referred to as "hood"). Unlike conventional one-piece engine hoods, the engine hood provided in this application embodiment can be divided into a left hood 102 and a right hood 103.

[0053] For example, taking the user's position outside vehicle 101 and facing the windshield of vehicle 101 as a reference position, the hood on the user's left is called "left hood 102", and the hood on the user's right is called "right hood 103". Figure 1 As shown, the position of the engine compartment covered by the left engine cover 102 is called the "left side position of the engine compartment" (abbreviated as "left side position"), and the position of the engine compartment covered by the right engine cover 103 is called the "right side position of the engine compartment" (abbreviated as "right side position").

[0054] The left engine cover 102 and the right engine cover 103 divide the engine cover of the vehicle 101 into two parts. Based on this mechanical mechanism, the left engine cover 102 and the right engine cover 103 can be opened and closed independently without affecting each other.

[0055] Normally, both the left engine cover 102 and the right engine cover 103 are closed. Figure 1 As shown. When vehicle 101 requires maintenance, the hood can be opened.

[0056] For example, when the hood is opened, only the left hood 102 or only the right hood 103 can be opened. The left hood 102 and the right hood 103 can also be opened together. When the left hood 102 and the right hood 103 are opened together, the state of the hoods is as shown in Figure 1 a "butterfly shape".

[0057] Based on the structure of the hoods described above, an example of how to control the hoods is also proposed in the embodiments of the present application.

[0058] Figure 2 is a scene schematic diagram for controlling the hoods provided by the embodiments of the present application.

[0059] For example, as shown in Figure 2 , a plurality of electronic control units (Electronic Control Unit, ECU, also referred to as controller) are generally configured in the vehicle, and the plurality of ECUs can realize mutual transmission of data through a communication connection mode.

[0060] Optionally, the connection mode between the plurality of ECUs of the vehicle includes a Controller Area Network (CAN) bus connection, a Local Interconnect Network (LIN) bus connection, a Flex Ray bus connection, a Media Oriented Systems Transport (MOST) bus connection, and an Ethernet connection. Correspondingly, the communication mode between the ECUs includes CAN bus communication, LIN bus communication, Flex Ray bus communication, MOST bus communication, and Ethernet communication. The embodiments of the present application take the CAN communication as an example for description.

[0061] It should be understood that when the ECUs realize data transmission through CAN communication, all the data is in the form of CAN signals and is transmitted through different CAN buses in the vehicle.

[0062] Optionally, the types of the CAN buses of the vehicle include a Power Train (PT) CAN bus, a Chassis (CH) CAN bus, a Body CAN bus 201, an Infomercial (Info) CAN bus, and a Diagnose (Diag) CAN bus.

[0063] As shown in Figure 2 , when the embodiments of the present application realize control of the hoods, the control is mainly realized through a hood controller (hood ECU) 203.

[0064] Specifically, the vehicle body CAN bus 201 is arranged with a central electronic module (Central Electronic Module, CEM, also referred to as "domain controller") 202 and a hood ECU 203. In addition, the vehicle body CAN bus 201 is generally arranged with an air conditioner (Air Condition) controller, a body control module (Body Control Module, BCM), and other ECUs. Each ECU on each CAN bus can be regarded as a node.

[0065] The CEM 202 can be understood as a general controller of the vehicle body CAN bus 201, and can control all ECUs (such as the hood ECU 203) under the vehicle body CAN bus 201. The CEM 202 and the hood ECU 203 can transmit data to each other to realize the opening and closing process of the hood.

[0066] In a possible implementation, when the hood is opened, the electric self-inhaling lock 209 is in an unlocked state, and the electric support rod 210 can be positively rotated to a fully open position. When the hood is closed, the electric self-inhaling lock 209 is self-inhaled to a fully locked position, and the electric support rod 210 is reversely rotated to a fully closed position.

[0067] Optionally, the hood can be at least one of a left hood and a right hood, and embodiments of the present application do not limit this.

[0068] Optionally, the left hood and the right hood can be controlled by the hood ECU 203. Alternatively, the left hood is controlled by a left hood ECU, and the right hood is controlled by a right hood ECU. Embodiments of the present application do not limit this. The following embodiments of the present application take the left hood and the right hood being controlled by the hood ECU 203 as an example to introduce the control process of the hood.

[0069] In a possible implementation, when the opening and closing of the hood are controlled, the user can achieve this based on a vehicle-mounted application (Application, App) on a terminal device.

[0070] Specifically, the CEM 202 can establish a communication connection with the terminal device through a remote information processing box (Telematics Box, T-Box, also referred to as a vehicle-mounted terminal, a remote communication module, etc.) 204 of the vehicle and a mobile communication module in the terminal device. Alternatively, the CEM 202 can establish a communication connection with the terminal device through a Bluetooth module 206 of the vehicle and a Bluetooth module in the terminal device. After the terminal device and the vehicle establish the communication connection, the user can use the vehicle-mounted App on the terminal device to realize the control process of the hood.

[0071] Optionally, when the vehicle establishes a communication connection with the terminal device through the T-Box 204 and the mobile communication module of the terminal device, the corresponding communication mode is referred to as "mobile communication"; when the vehicle establishes a communication connection with the terminal device through the Bluetooth module 206 and the Bluetooth module of the terminal device, the corresponding communication mode is referred to as "Bluetooth communication".

[0072] For example, if the communication mode between the terminal device and the vehicle is mobile communication, when controlling the opening and closing of the hood, the user can open the vehicle-mounted App and control the terminal device to display a hood control interface in the display area. In the hood control interface, the user can select the "open" control or the "close" control by clicking or outputting a voice (for example, opening the hood or closing the hood).

[0073] After the terminal device receives the clicking operation or the output voice of the user in the display interface, the terminal device can generate an opening instruction or a closing instruction and send the opening instruction or the closing instruction to the CEM 202 through the mobile communication module of the terminal device and the T-Box 204 of the vehicle. Further, the CEM 202 sends the opening instruction or the closing instruction to the hood ECU 203, so that the hood ECU 203 controls the opening or closing of the hood.

[0074] For another example, if the communication mode between the terminal device and the vehicle is Bluetooth communication, when controlling the opening and closing of the hood, the user can open the vehicle-mounted App and control the terminal device to display a hood control interface in the display area. In the hood control interface, the user can select the "open" control or the "close" control by clicking or outputting a voice (for example, opening the hood or closing the hood).

[0075] After the terminal device receives the clicking operation or the output voice of the user in the display interface, the terminal device can generate an opening instruction or a closing instruction and send the opening instruction or the closing instruction to the CEM 202 through the Bluetooth module of the terminal device and the Bluetooth module 206 of the vehicle. Further, the CEM 202 sends the opening instruction or the closing instruction to the hood ECU 203, so that the hood ECU 203 controls the opening or closing of the hood.

[0076] In another possible implementation, when controlling the opening and closing of the hood, the CEM 202 can also be connected with the multimedia controller 205 in the vehicle, so that the user can control the opening and closing of the hood by voice control or clicking operation.

[0077] For example, the user can output a voice such as "open the hood" or "close the hood". The multimedia controller 205 acquires the voice output by the user through the microphone and generates an opening instruction or a closing instruction according to the voice. The multimedia controller 205 can further send the opening instruction or the closing instruction to the CEM 202. The CEM 202 further sends the opening instruction or the closing instruction to the hood ECU 203, so that the hood ECU 203 controls the hood to open or close.

[0078] For another example, when the multimedia host displays the hood control interface in the display area, the user can also click the "open" control or the "close" control through a click operation. The multimedia controller 205 generates an opening instruction or a closing instruction in response to the click operation of the user. The multimedia controller 205 can further send the opening instruction or the closing instruction to the CEM 202. The CEM 202 further sends the opening instruction or the closing instruction to the hood ECU 203, so that the hood ECU 203 controls the hood to open or close.

[0079] In another possible implementation, when controlling the opening and closing of the hood, the CEM 202 can also be connected with the vehicle-mounted camera 207 in the vehicle, so that the user can control the opening and closing of the hood through a gesture adjustment operation.

[0080] Optionally, the vehicle-mounted camera 207 in the embodiment of the application can be an outside camera or an inside camera.

[0081] For example, the vehicle-mounted camera 207 can be arranged around the hood of the vehicle. The CEM 202 can pre-store a preset gesture corresponding to the opening of the hood and a preset gesture corresponding to the closing of the hood. When the hood needs to be opened or closed, the user can make the preset gesture corresponding to the opening of the hood or the preset gesture corresponding to the closing of the hood based on a gesture adjustment operation. The vehicle-mounted camera 207 can acquire an image of the gesture adjustment operation of the user through shooting and send the image of the gesture adjustment operation to the CEM 202. The CEM 202 compares and determines that the gesture adjustment operation matches the preset gesture corresponding to the opening of the hood, and generates an opening instruction and sends the opening instruction to the hood ECU 203, so that the hood ECU 203 controls the hood to open. Alternatively, the CEM 202 determines that the gesture adjustment operation matches the preset gesture corresponding to the closing of the hood, and generates a closing instruction and sends the closing instruction to the hood ECU 203, so that the hood ECU 203 controls the hood to close.

[0082] In another possible implementation, when controlling the opening and closing of the hood, the CEM 202 can also be connected with the micro switch 208 of the hood, so that the user can change the state of the micro switch 208 through a click operation to control the hood.

[0083] For example, when a user needs to open the hood, they can click the microswitch 208 on the hood to adjust its state. After the CEM 202 obtains the state of the microswitch 208, it generates an opening command and sends it to the hood ECU 203, so that the hood ECU 203 controls the hood to open. Similarly, when a user needs to close the hood, they can click the microswitch 208 on the hood to adjust its state. After the CEM 202 obtains the state of the microswitch 208, it generates a closing command and sends it to the hood ECU 203, so that the hood ECU 203 controls the hood to close.

[0084] Through the above methods, the embodiments of this application can realize the process of flexibly opening and closing the cover.

[0085] After introducing the structure and control process of the engine hood, the following section introduces a vehicle engine compartment safety control method provided by an embodiment of this application.

[0086] Figure 3 This is a schematic flowchart illustrating a vehicle engine compartment safety control method provided in an embodiment of this application. It should be understood that this method can be applied to, for example... Figure 2 The scenario shown can be specifically applied to Figure 2 The CEM202, hood ECU203, or any ECU in the vehicle are used as examples. The following embodiments of this application will use the CEM202 as an example to provide a detailed description of a vehicle engine compartment safety control method provided in this application.

[0087] For example, such as Figure 3 As shown, the method 300 includes:

[0088] 301. When the vehicle is powered on, acquire the environmental parameters of the engine compartment. The environmental parameters are used to represent the environmental conditions inside the engine compartment.

[0089] It should be understood that the "power-on" state typically refers to the vehicle's high-voltage system being activated; the vehicle cannot operate when the high-voltage system is not activated. The corresponding "power-off" state typically refers to the vehicle's high-voltage system being shut down.

[0090] When the vehicle is powered on, it indicates that the vehicle is in the starting state. To prevent abnormalities in the engine compartment that could threaten the user's safety while the vehicle is in the starting state, this application embodiment can monitor the safety of the engine compartment by acquiring environmental parameters. These environmental parameters represent the internal environmental conditions of the engine compartment, such as temperature and humidity.

[0091] Optionally, the environmental parameter comprises at least one of a smoke concentration, a temperature and a noise decibel of the engine compartment.

[0092] Optionally, the smoke concentration sensor comprises a carbon monoxide concentration sensor, a carbon dioxide concentration sensor, a hydrogen sulfide concentration sensor, etc., and the embodiments of the present application are not limited thereto.

[0093] For example, when the smoke concentration of the engine compartment is acquired, the CEM can acquire the smoke concentration through a smoke concentration sensor in the engine compartment; when the temperature of the engine compartment is acquired, the CEM can acquire the temperature through a temperature sensor in the engine compartment; and when the noise decibel of the engine compartment is acquired, the CEM can acquire the noise decibel through a noise sensor in the engine compartment.

[0094] Specifically, based on the structure of the engine cover in the embodiments of the present application, the first environmental parameter of the left side position of the engine compartment corresponding to the left cover and the second environmental parameter of the right side position of the engine compartment corresponding to the right cover can be acquired respectively. Correspondingly, the first environmental parameter comprises at least one of a first smoke concentration, a first temperature and a first noise decibel, and the second environmental parameter comprises at least one of a second smoke concentration, a second temperature and a second noise decibel.

[0095] The CEM can acquire the first smoke concentration through a smoke concentration sensor in the left side position, and acquire the second smoke concentration through a smoke concentration sensor in the right side position; similarly, the CEM can acquire the first temperature through a temperature sensor in the left side position, acquire the second temperature through a temperature sensor in the right side position, acquire the first noise decibel through a noise sensor in the left side position, and acquire the second noise decibel through a noise sensor in the right side position.

[0096] Further, after the environmental parameter is acquired, the CEM can compare the environmental parameter with a preset condition to determine whether the engine compartment is abnormal.

[0097] In a possible implementation manner, when the CEM determines whether the engine compartment is abnormal according to the environmental parameter, the CEM specifically comprises:

[0098] In a case where the smoke concentration is greater than a preset concentration, and / or the temperature is greater than a preset temperature, and / or the noise decibel is greater than a preset decibel, it is determined that the environmental parameter satisfies the preset condition.

[0099] In a case where the smoke concentration is less than or equal to the preset concentration, the temperature is less than or equal to the preset temperature, and the noise decibel is less than or equal to the preset decibel, it is determined that the environmental parameter does not satisfy the preset condition.

[0100] It should be understood that, generally, excessive smoke concentration in the engine compartment indicates that a fire can be occurring in the engine compartment; excessive temperature in the engine compartment is usually caused by: clogged air filter; excessive gap between cylinder gasket and cylinder liner; insufficient coolant; abnormal rotation of the fan; excessive noise in the engine compartment can be caused by: aged fuel, aged engine foot pad, loose parts in the engine compartment, clogged air intake system or exhaust system, etc.

[0101] Therefore, based on at least one of the above smoke concentration, temperature, and noise decibel, the CEM can determine whether the engine compartment of the vehicle is abnormal.

[0102] In the above technical solution, according to the state of the engine compartment during operation, the environmental parameter of the present application includes at least one of the smoke concentration, the temperature, and the noise decibel. When the environmental parameter meets the preset condition, specifically when the smoke concentration is greater than the preset concentration, and / or the temperature is greater than the preset temperature, and / or the noise decibel is greater than the preset decibel, it is determined that the environmental parameter meets the preset condition. On the contrary, when the smoke concentration is less than or equal to the preset concentration, and / or the temperature is less than or equal to the preset temperature, and / or the noise decibel is less than or equal to the preset decibel, it is determined that the environmental parameter does not meet the preset condition. Through the above judgment of smoke concentration, temperature, and noise decibel, the problems of fire and abnormal operation of components in the engine compartment can be avoided, effectively ensuring the safety of the engine compartment.

[0103] Specifically, based on the different positions, the environmental parameter is divided into a first environmental parameter and a second environmental parameter, and the present application embodiment determines that the environmental parameter meets the preset condition, specifically including at least one of the following:

[0104] In the case where the first smoke concentration is greater than the preset concentration, and / or the first temperature is greater than the preset temperature, and / or the first noise decibel is greater than the preset decibel, it is determined that the first environmental parameter meets the preset condition;

[0105] In the case where the second smoke concentration is greater than the preset concentration, and / or the second temperature is greater than the preset temperature, and / or the second noise decibel is greater than the preset decibel, it is determined that the second environmental parameter meets the preset condition.

[0106] For example, assuming that the preset concentration is 1%, the preset temperature is 90°C, and the preset decibel is 80 decibels. If the first smoke concentration sensor in the left position obtains a first smoke concentration of 2%, the CEM determines that the first environmental parameter meets the preset condition. If the temperature sensor in the right position obtains a second temperature of 200°C, the CEM determines that the second environmental parameter meets the preset condition. If the first smoke concentration sensor in the left position obtains a first smoke concentration of 2% and the temperature sensor in the right position obtains a second temperature of 200°C, the CEM determines that the first environmental parameter and the second environmental parameter both meet the preset condition.

[0107] In the technical solution, the engine cover is divided into a left cover and a right cover, and the first environmental parameter of the left side position corresponding to the left cover and the second environmental parameter of the right side position corresponding to the right cover can be monitored separately. Based on the above process, when the environmental parameter meets the preset condition, two scenarios can be distinguished: in the case that the first smoke concentration is greater than the preset concentration, and / or the first temperature is greater than the preset temperature, and / or the first noise decibel is greater than the preset decibel, it is determined that the first environmental parameter meets the preset condition; in the case that the second smoke concentration is greater than the preset concentration, and / or the second temperature is greater than the preset temperature, and / or the second noise decibel is greater than the preset decibel, it is determined that the second environmental parameter meets the preset condition. The above monitoring of the environmental parameters of different sides of the engine compartment can achieve the effect of separately controlling the left cover and the right cover.

[0108] 302, in the case that the environmental parameter meets the preset condition, determining a target position where an abnormality occurs in the engine compartment, the target position including a left side position and a right side position of the engine compartment.

[0109] In step 301, if the CEM determines that the environmental parameter meets the preset condition, the target position can be further determined by the environmental parameter.

[0110] In a possible implementation, when the target position where an abnormality occurs in the engine compartment is determined, the method specifically includes:

[0111] In the case that the first environmental parameter meets the preset condition, the left side position is determined as the target position;

[0112] In the case that the second environmental parameter meets the preset condition, the right side position is determined as the target position;

[0113] In the case that the first environmental parameter meets the preset condition and the second environmental parameter meets the preset condition, the left side position and the right side position are determined as the target position.

[0114] For example, it is assumed that the preset concentration is 1%, the preset temperature is 90°C, and the preset decibel is 80 decibels. If the smoke concentration sensor in the left side position obtains a first smoke concentration of 2%, the CEM determines that the first environmental parameter meets the preset condition. Correspondingly, the CEM determines the left side position as the target position. If the temperature sensor in the right side position obtains a second temperature of 200°C, the CEM determines that the second environmental parameter meets the preset condition. Correspondingly, the CEM determines the right side position as the target position. If the smoke concentration sensor in the left side position obtains a first smoke concentration of 2% and the temperature sensor in the right side position obtains a second temperature of 200°C, the CEM determines that the first environmental parameter and the second environmental parameter meet the preset condition at the same time. Correspondingly, the CEM determines the left side position and the right side position as the target position.

[0115] In the technical solution, based on the separate monitoring of the first and second environment parameters, three scenarios are also determined when determining the target position. In the first scenario, the left position is determined as the target position when the first environment parameter meets the preset condition. In the second scenario, the right position is determined as the target position when the second environment parameter meets the preset condition. In the third scenario, the left and right positions are determined as the target positions when the first and second environment parameters meet the preset conditions. The above process realizes the determination of different target positions according to the types of the environment parameters, thereby ensuring the accuracy of the determination of the target position.

[0116] 303. Trigger a target prompt information according to the target position and the environment parameter, the target prompt information being used to prompt that the target position of the engine compartment is abnormal.

[0117] After the target position is determined, in order to timely remind the user, the embodiment of the present application can also trigger a target prompt information based on the target position and the environment parameter. Specifically, the target prompt information is generated according to the target position and the environment parameter, and the display device of the vehicle is controlled to display the target prompt information, and the audio playing device of the vehicle is controlled to broadcast the target prompt information.

[0118] According to the target position and the environment parameter, the target prompt information is generated;

[0119] The display device of the vehicle is controlled to display the target prompt information, and the audio playing device of the vehicle is controlled to broadcast the target prompt information.

[0120] It should be understood that when reminding the user, the user needs to know the general situation of the current abnormality, for example, the position (target position) where the abnormality occurs and the cause (environment parameter) of the abnormality, so that the user can formulate a corresponding processing scheme according to the abnormality.

[0121] Therefore, when the abnormality occurs in the engine compartment of the vehicle, the CEM can first generate a target prompt information according to the target position and the environment parameter. Further, the display device of the vehicle is controlled to display the target prompt information, and the audio playing device of the vehicle is controlled to broadcast the target prompt information.

[0122] Optionally, the display device includes a multimedia host, a rear liquid crystal display screen, a display screen of a head-up display (HUD) system, an instrument panel, etc., and the embodiment of the present application does not limit this. The embodiment of the present application takes the multimedia host as an example for illustration.

[0123] For example, Figure 2As shown, after the target prompt information is generated, the CEM 202 can control the multimedia host of the vehicle to display the target prompt information in the display area through the multimedia controller 205, such as a text pop-up window of "The first smoke concentration at the left position is 5%, please pay attention to the possible danger in the engine compartment". Further, the CEM 202 can also control the speaker in the vehicle to broadcast the target prompt information, such as a voice of "The first smoke concentration at the left position is 5%, please pay attention to the possible danger in the engine compartment".

[0124] In the above technical solution, when it is determined that the vehicle has an abnormality, in order to timely remind the user, the present application provides a triggering process of target prompt information. Specifically, the vehicle can generate target prompt information according to the target position and the environmental parameter. Then further control the display device to display the target prompt information, and the audio playback device to broadcast the target prompt information. Thus, a double reminding mode of voice reminding and text reminding is realized when the engine compartment has an abnormality, the user is quickly and diversely reminded, so that the user can timely pay attention to and handle the abnormality. Thus, the life safety of the user and the safety of the vehicle are ensured.

[0125] Further, when the engine compartment has an abnormality, in addition to reminding the user to pay attention to prevention, the present application embodiment also provides an automatic handling mode of the abnormality.

[0126] In a possible implementation manner, when the CEM automatically handles the abnormality of the target position, specifically includes:

[0127] In the case that the environmental parameter is smoke concentration, the extinguishing system in the engine compartment is controlled to be turned on to reduce the smoke concentration corresponding to the target position;

[0128] In the case that the environmental parameter is temperature, the cooling system in the engine compartment is controlled to be turned on to reduce the temperature corresponding to the target position.

[0129] For example, assuming that the smoke concentration is greater than a preset concentration 1%, the CEM can send an opening instruction to the extinguishing system controller in the engine compartment, so that the extinguishing system controller controls the extinguisher in the extinguishing system to be opened to reduce the smoke concentration.

[0130] Optionally, the type of the extinguisher includes an aerosol extinguisher, a dry powder extinguisher, an ultra-fine dry powder extinguisher, a carbon dioxide extinguisher, a water-based extinguisher, etc., and the present application embodiment does not limit this.

[0131] For another example, assuming that the temperature is greater than a preset temperature 90℃, the CEM can send an opening instruction to the cooling system controller in the engine compartment, so that the cooling system controller controls the cooling system to run to dissipate the heat in the engine compartment to the air to achieve the purpose of cooling.

[0132] In the technical solution, the smoke concentration is usually an environmental parameter when a fire accident occurs in the vehicle. In order to handle the abnormality in time, the application can also intelligently start the fire extinguishing system in the engine compartment to extinguish the fire when the smoke concentration in the vehicle is high, so as to reduce the smoke concentration in the engine compartment; or the cooling system in the engine compartment can be started to reduce the temperature when the temperature in the engine compartment is high. The above process ensures that the abnormality of the vehicle is automatically handled in time when the vehicle is abnormal, avoids further aggravation and spread of the abnormality, and ensures the safety of the vehicle.

[0133] 304, in the case where the vehicle speed is less than or equal to the preset vehicle speed, the target hood corresponding to the target position is controlled to be opened, and the target hood includes a left hood corresponding to a left position and a right hood corresponding to a right position.

[0134] It should be understood that the hood in the embodiment of the application includes a left hood and a right hood. After prompting the user in the form of target prompt information, the target hood corresponding to the target position can also be opened in time when the vehicle speed is in a low range in the embodiment of the application.

[0135] Specifically, when the target hood is opened, the CEM can first determine the target hood corresponding to the target position from the left hood and the right hood of the vehicle according to the target position.

[0136] It should also be understood that in the case where the smoke concentration is high, it indicates that the engine compartment of the vehicle may be on fire. In this case, if the engine hood is opened, it may cause air to fully contact the burning material and increase the fire, and in serious cases, it may cause the vehicle to explode, threatening the personal safety and property safety of people around the vehicle. Therefore, the opening of the target hood in the embodiment of the application is mainly aimed at the scene where the temperature is too high and the noise is too loud.

[0137] Further, when the target hood is opened, the embodiment of the application can provide two ways, namely manual opening and automatic opening. Among them, manual opening refers to the need for user participation, and the opening of the target hood is triggered by various operations of the user; automatic opening refers to the need for user participation, and the CEM directly controls the opening of the target hood. The following embodiment of the application takes the target hood as the left hood, and illustrates the opening process of the target hood.

[0138] In one possible implementation, the automatic opening of the target hood specifically includes:

[0139] In the case where the vehicle speed is less than or equal to the preset vehicle speed, the target hood is controlled to be opened.

[0140] Optionally, the preset vehicle speed is 0 km / h.

[0141] For example, when the CEM obtains the current vehicle speed of 0 km / h through the instrument controller, or obtains the vehicle speed of 0 km / h through the controller of the Anti-Lock Brake System (ABS) directly connected with the vehicle speed sensor, the CEM sends a left hood opening instruction to the hood ECU to control the left hood of the vehicle to be automatically opened by the hood ECU.

[0142] In another possible implementation, the manner of manually opening the target hood specifically includes:

[0143] In the case that the vehicle speed is less than or equal to the preset vehicle speed, the target hood is controlled to be opened in response to the opening instruction of the target hood, and the triggering manner of the opening instruction includes any one of voice control, click operation, and gesture adjustment operation.

[0144] Based on the voice control, click operation, and gesture adjustment operation, each control manner under the manual opening of the target hood will be introduced in detail below in combination with the description in Figure 2

[0145] Firstly, voice control

[0146] For example, when the communication manner between the vehicle and the terminal device is mobile communication, the user can open the vehicle-mounted App installed on the terminal device, and control the terminal device to display a hood control interface in the display area. In the hood control interface, the user can select the "open" control corresponding to the left hood by outputting a voice, for example, the voice of "opening the left hood".

[0147] The terminal device receives the voice of the user, generates a left hood opening instruction, and sends the left hood opening instruction to the CEM 202 through the mobile communication module of the terminal device and the T-Box 204 of the vehicle. Further, the CEM 202 sends the left hood opening instruction to the hood ECU 203, so that the hood ECU 203 controls the left hood to be opened according to the left hood opening instruction.

[0148] For another example, when the communication manner between the vehicle and the terminal device is Bluetooth communication, the user can open the vehicle-mounted App installed on the terminal device, and control the terminal device to display a hood control interface in the display area. In the hood control interface, the user can select the "open" control corresponding to the left hood by outputting a voice, for example, the voice of "opening the left hood".

[0149] The terminal device receives the voice of the user, generates a left hood opening instruction, and sends the left hood opening instruction to the CEM 202 through the Bluetooth module of the terminal device and the Bluetooth module 206 of the vehicle. The CEM 202 sends the left hood opening instruction to the hood ECU 203, so that the hood ECU 203 controls the left hood to be opened according to the left hood opening instruction.​

[0150] Further exemplary, the user can also control the multimedia host to display the hood control interface in the display area. In the hood control interface, the user can select the "on" control corresponding to the left hood by outputting a voice, such as a voice of "open the left hood".

[0151] The multimedia controller 205 receives the voice of the user, generates a left hood opening instruction and sends it to the CEM 202. Further, the CEM 202 sends the left hood opening instruction to the hood ECU 203, so that the hood ECU 203 controls the left hood to open according to the left hood opening instruction.

[0152] Second: click operation

[0153] Exemplary, when the communication mode between the vehicle and the terminal device is mobile communication, the user can open the vehicle-mounted App installed in the terminal device, and control the terminal device to display the hood control interface in the display area. In the hood control interface, the user can select the "on" control corresponding to the left hood by clicking operation.

[0154] The terminal device receives the click operation of the user, generates a left hood opening instruction, and sends it to the CEM 202 through the mobile communication module of the terminal device and the T-Box 204 of the vehicle. Further, the CEM 202 sends the left hood opening instruction to the hood ECU 203, so that the hood ECU 203 controls the left hood to open according to the left hood opening instruction.

[0155] Further exemplary, when the communication mode between the vehicle and the terminal device is Bluetooth communication, the user can open the vehicle-mounted App installed in the terminal device, and control the terminal device to display the hood control interface in the display area. In the hood control interface, the user can select the "on" control corresponding to the left hood by clicking operation.

[0156] The terminal device receives the voice of the user, generates a left hood opening instruction, and sends it to the CEM 202 through the Bluetooth module of the terminal device and the Bluetooth module 206 of the vehicle. Further, the CEM 202 sends the left hood opening instruction to the hood ECU 203, so that the hood ECU 203 controls the left hood to open according to the left hood opening instruction.

[0157] Further exemplary, the user can also control the multimedia host to display the hood control interface in the display area. In the hood control interface, the user can select the "on" control corresponding to the left hood by clicking operation.

[0158] The multimedia controller 205 receives the click operation of the user, generates a left hood opening instruction and sends it to the CEM 202. Further, the CEM 202 sends the left hood opening instruction to the hood ECU 203, so that the hood ECU 203 controls the left hood to open according to the left hood opening instruction.

[0159] Further, the user can also click the micro switch 208 of the left hood through a click operation to adjust the state of the micro switch 208. The CEM 202 generates a left hood opening instruction based on the state of the micro switch 208. And sends the left hood opening instruction to the hood ECU 203, so that the hood ECU 203 controls the left hood to open according to the left hood opening instruction.

[0160] Third: gesture adjustment operation

[0161] Exemplarily, assuming that the preset gesture for opening the left hood stored in the CEM 202 is "right hand victory gesture". Then when the user needs to open the left hood, he can make the preset gesture. The vehicle-mounted camera 207 can capture the image of the user's gesture adjustment operation and send it to the CEM 202. The CEM 202 determines the left hood opening instruction according to the image. Then sends the left hood opening instruction to the hood ECU 203, so that the hood ECU 203 controls the left hood to open.

[0162] In the above technical solution, when opening the target hood, the present application can provide two opening scenes. The first is a manual opening scene, in which the user manually controls the opening process of the target hood. Specifically, the user can control the target hood to open through various opening methods such as voice control (for example, "open the target hood" voice), click operation (for example, by selecting the "open" control of the target hood through a click operation), gesture adjustment operation (for example, making a gesture corresponding to opening the target hood) and the like.

[0163] The second is an automatic opening scene, in which the user does not need to participate. As long as the vehicle detects that the vehicle speed is less than or equal to the preset vehicle speed, the target hood is automatically triggered to open automatically.

[0164] The above two opening scenes ensure that the opening method of the target hood is flexible and various, and improve the opening efficiency of the target hood.

[0165] In summary, in order to ensure and monitor the safety of the vehicle when the vehicle is in the power-on state, the application provides a vehicle engine compartment safety control method. Specifically, the environmental parameters of the engine compartment can be obtained, wherein the environmental parameters can represent the cabin environmental state of the engine compartment. Further, by comparing the environmental parameters with the preset conditions, if the environmental parameters meet the preset conditions, it is determined that the vehicle engine compartment is abnormal, and the target position of the abnormality is confirmed. The target position can be the left position and the right position of the engine compartment. Then, through the target position and the environmental parameters, the target prompt information is triggered to remind the user of the abnormality of the target position. Finally, when the vehicle speed is less than or equal to the preset vehicle speed, the application can further control the target hood corresponding to the target position to open. The target hood includes a left hood corresponding to the left position and a right hood corresponding to the right position.

[0166] The above method for monitoring the safety of the engine compartment through environmental parameters is simple, accurate and efficient. When the vehicle is abnormal, the user can be reminded to timely alert and handle the abnormality of the target position, thereby ensuring the safety of the user when the user is riding the vehicle. Finally, based on the correspondence between the target hood and the target position, the application can flexibly control the target hood corresponding to the target position to open when the vehicle speed is low. On the one hand, the left hood and the right hood can be flexibly opened without interfering with each other. On the other hand, opening the target hood can also achieve the effect of intelligently handling the abnormality in the vehicle.

[0167] According to the state of the engine compartment during operation, the environmental parameters of the application include at least one of smoke concentration, temperature and noise decibel. When the environmental parameters meet the preset conditions, specifically when the smoke concentration is greater than the preset concentration, and / or the temperature is greater than the preset temperature, and / or the noise decibel is greater than the preset decibel, it is determined that the environmental parameters meet the preset conditions. Conversely, when the smoke concentration is less than or equal to the preset concentration, and / or the temperature is less than or equal to the preset temperature, and / or the noise decibel is less than or equal to the preset decibel, it is determined that the environmental parameters do not meet the preset conditions. By judging the smoke concentration, temperature and noise decibel, the problems of fire and abnormal operation of components in the engine compartment can be avoided, thereby effectively ensuring the safety of the engine compartment.

[0168] The engine-based engine hood is divided into a left engine hood and a right engine hood, and the application can separately monitor a first environmental parameter of a left side position corresponding to the left engine hood and a second environmental parameter of a right side position corresponding to the right engine hood. Based on the above process, when it is determined that the environmental parameter meets the preset condition, two scenarios can be divided: in the case that the first smoke concentration is greater than the preset concentration, and / or the first temperature is greater than the preset temperature, and / or the first noise decibel is greater than the preset decibel, it is determined that the first environmental parameter meets the preset condition; in the case that the second smoke concentration is greater than the preset concentration, and / or the second temperature is greater than the preset temperature, and / or the second noise decibel is greater than the preset decibel, it is determined that the second environmental parameter meets the preset condition. The above monitoring of the environmental parameters of different sides of the engine compartment can achieve the effect of separately controlling the left engine hood and the right engine hood.

[0169] Based on the above separate monitoring process of the first environmental parameter and the second environmental parameter, there are also three scenarios when determining the target position. The first scenario is to determine the left side position as the target position when the first environmental parameter meets the preset condition; the second scenario is to determine the right side position as the target position when the second environmental parameter meets the preset condition; and the third scenario is to determine the left side position and the right side position as the target position when both the first environmental parameter and the second environmental parameter meet the preset condition. The above process realizes the determination of different target positions according to the types of environmental parameters, ensuring the accuracy of target position determination.

[0170] When it is determined that the vehicle has an abnormality, in order to timely remind the user, the application provides a triggering process of target prompt information. Specifically, the vehicle can generate target prompt information according to the target position and the environmental parameter. Then further control the display device to display the target prompt information, and the audio playing device to broadcast the target prompt information. Thus, when the engine compartment has an abnormality, the application realizes a double reminding method based on voice and text, quickly and diversely reminding the user, so that the user can timely pay attention to and handle the abnormality. Thus, the safety of the user and the vehicle is ensured.

[0171] When the target engine hood is opened, the application can provide two opening scenarios. The first scenario is a manual opening scenario, in which the user needs to manually control the opening process of the target engine hood. Specifically, the user can control the target engine hood to open through various opening methods such as voice control (for example, the voice of "opening the target engine hood"), click operation (for example, selecting the "open" control of the target engine hood through click operation), gesture adjustment operation (for example, making a gesture corresponding to opening the target engine hood), etc.

[0172] The second scenario is an automatic opening scenario, in which the user does not need to participate. As long as the vehicle detects that the vehicle speed is less than or equal to the preset vehicle speed, the target engine hood is automatically triggered to open automatically.

[0173] The two opening scenarios described above ensure that the target hood can be opened in a flexible and diverse manner, thereby improving the opening efficiency of the target hood.

[0174] Smoke concentration is a typical environmental parameter during a vehicle fire. To address this anomaly promptly, this application can also intelligently activate the fire suppression system in the engine compartment when the smoke concentration inside the vehicle is high, thereby reducing the smoke concentration. Alternatively, it can activate the cooling system in the engine compartment when the temperature is high. These processes ensure timely and automatic handling of vehicle anomalies, preventing further escalation and spread of the anomaly, and guaranteeing vehicle safety.
