Description

Technical Field

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

[0002] Currently in the vehicle industry, with the continuous upgrading and reform of vehicle production technology, the structure of vehicles is gradually changing.

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

[0004] Based on the above-mentioned structure of the engine hood, how to ensure the safety of the engine compartment of the vehicle and reasonably control the opening or closing of the engine hood has become an urgent problem to be solved. Summary of the invention

[0005] The present application provides a vehicle engine compartment safety control method, device, vehicle and storage medium, which can accurately determine the target position where the engine compartment has abnormality based on the environmental parameters in the vehicle engine compartment when the vehicle engine compartment is divided into a left engine compartment and a right engine compartment, and further intelligently and flexibly control the opening of the engine compartment 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 comprising: when the vehicle is in a powered-on state, obtaining environmental parameters of the engine compartment of the vehicle, the environmental parameters being used to represent the cabin environmental state of the engine compartment; when the environmental parameters meet preset conditions, determining a target position where an abnormality occurs in the engine compartment, the target position including a left position and a right position of the engine compartment; based on the target position and the environmental parameters, triggering target prompt information, the target prompt information being used to prompt that an abnormality occurs at the target position of the engine compartment; when the vehicle speed is less than or equal to a preset speed, controlling a target hood corresponding to the target position to open, the target hood including a left hood corresponding to the left position, and a right hood corresponding to the right position.

[0007] In the above technical solution, when the vehicle is in the power-on state, in order to ensure and monitor the safety of the vehicle, the present 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 environment state of the engine compartment. Further, by comparing the environmental parameters with the preset conditions, when the environmental parameters meet the preset conditions, it is determined that an abnormality has occurred in the vehicle engine compartment, and the target position where the abnormality has occurred is confirmed. The target position can be the left position or 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 it is monitored that the vehicle speed is less than or equal to the preset speed, the present application can further control the target hood corresponding to the target position to open. Among them, the target hood includes a left hood corresponding to the left position, and a right hood corresponding to the right position.

[0008] The above-mentioned monitoring of the safety of the engine compartment through environmental parameters is simple, accurate and efficient. And when an abnormality occurs in the vehicle, it can humanely remind the user to be alert and deal with the abnormality of the target position in a timely manner, achieving the effect of ensuring the safety of the user in time when the user is riding in the vehicle. Finally, based on the correspondence between the target hood and the target position, the present application can also flexibly control the opening of the target hood corresponding to the target position when the vehicle speed is low. On the one hand, it achieves the flexible opening of the left hood and the right hood without interfering with each other; on the other hand, by opening the target hood, it can also achieve the effect of intelligently handling abnormalities in the vehicle.

[0009] In combination with the first aspect, in certain possible implementations, the environmental parameter includes at least one of smoke concentration, temperature and noise decibel. After obtaining the environmental parameter of the engine compartment of the vehicle, the method further includes: 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 parameter meets the preset condition; 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, determining that the environmental parameter does not meet the preset condition.

[0010] In the above technical solution, according to the state of the engine compartment during operation, the environmental parameters of the present application include at least one of smoke concentration, temperature and noise decibel. When judging that 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. 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 parameters do not meet the preset conditions. Through the above-mentioned judgment of smoke concentration, temperature and noise decibel, it is possible to avoid fire and abnormal operation of components in the engine compartment, and effectively ensure the safety of the engine compartment.

[0011] In combination with the first aspect and the above-mentioned implementation manner, in some possible implementation manners, the environmental parameter includes a first environmental parameter corresponding to the left position and a second environmental parameter corresponding to the right position, the first environmental parameter includes at least one of a first smoke concentration, a first temperature and a first noise decibel, and the second environmental parameter includes at least one of a second smoke concentration, a second temperature and a second noise decibel, and 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 parameter satisfies the preset condition includes at least one of the following: when 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, determining that the first environmental parameter satisfies the preset condition; when 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, determining that the second environmental parameter satisfies the preset condition.

[0012] In the above technical solution, based on the engine hood being divided into a left hood and a right hood, the present application can separately monitor the first environmental parameter of the left position corresponding to the left hood, and the second environmental parameter of the right position corresponding to the right hood. Based on the above process, when judging that the environmental parameters meet the preset conditions, it can also be divided into two scenarios: when 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 conditions; when 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 conditions. The above-mentioned monitoring of the environmental parameters on different sides of the engine compartment can achieve the effect of subsequently separately controlling the left hood and the right hood.

[0013] In combination with the first aspect and the above-mentioned implementation methods, in some possible implementation methods, the target position where the abnormality occurs in the engine compartment is determined when the environmental parameter satisfies the preset condition, including: when the first environmental parameter satisfies the preset condition, the left position is determined as the target position; when the second environmental parameter satisfies the preset condition, the right position is determined as the target position; when the first environmental parameter satisfies the preset condition and the second environmental parameter satisfies 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 above-mentioned separate monitoring process of the first environmental parameter and the second environmental parameter, there are also three corresponding scenarios when determining the target position. The first is to determine the left position as the target position when the first environmental parameter meets the preset conditions; the second is to determine the right position as the target position when the second environmental parameter meets the preset conditions; the third is to determine the left position and the right position as the target position at the same time when both the first environmental parameter and the second environmental parameter meet the preset conditions. The above process realizes the corresponding determination of different target positions according to the different types of environmental parameters, thereby ensuring the accuracy of the target position determination.

[0015] In combination with the first aspect and the above-mentioned implementation methods, in some possible implementation methods, the target prompt information is triggered according to the target position and the environmental parameters, including: generating the target prompt information according to the target position and the environmental parameters; controlling the display device of the vehicle to display the target prompt information, and the audio playback device of the vehicle to broadcast the target prompt information.

[0016] In the above technical solution, when it is determined that the vehicle has an abnormality, in order to promptly remind the user, this application provides a triggering process for target prompt information. Specifically, the vehicle can generate target prompt information based on the target position and environmental parameters. Then further control the display device to display the target prompt information, and the audio playback device to broadcast the target prompt information. Thus, when an abnormality occurs in the engine compartment, based on the dual reminder method of voice reminder and text reminder, the user can be quickly and diversely reminded, so that the user can pay attention to and handle the abnormality in time. Thereby ensuring the safety of the user's life and the safety of the vehicle.

[0017] In combination with the first aspect and the above-mentioned implementation methods, in some possible implementation methods, the environmental parameter includes at least one of temperature and noise decibels, and when the vehicle speed is less than or equal to a preset speed, the target hood corresponding to the target position is controlled to open, including any of the following: when the vehicle speed is less than or equal to the preset speed, in response to an opening instruction of the target hood, the target hood is controlled to open, and the triggering method of the opening instruction includes any one of voice control, click operation, and gesture adjustment operation; when the vehicle speed is less than or equal to the preset speed, the target hood is controlled to open.

[0018] In the above technical solution, when opening the target hood, the present application can provide two opening scenarios. The first 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 opening of the target hood through a variety of opening methods such as voice control (e.g., voice of "open the target hood"), click operation (e.g., selecting the "open" control of the target hood by clicking), gesture adjustment operation (e.g., making a gesture corresponding to opening the target hood), etc.

[0019] The second is the automatic opening scenario. In this scenario, no user participation is required. As long as the vehicle detects that the speed is less than or equal to the preset speed, the target hood will be automatically triggered to open.

[0020] The above two opening scenarios ensure that the opening methods of the target hood are flexible and diverse, and improve the opening efficiency of the target hood.

[0021] In combination with the first aspect and the above-mentioned implementation methods, in some possible implementation methods, the environmental parameter includes at least one of smoke concentration and temperature. After the target prompt information is triggered according to the target position and the environmental parameter, the method also includes at least one of the following: when the environmental parameter is the smoke concentration, controlling the fire extinguishing system in the engine compartment to turn on to reduce the smoke concentration corresponding to the target position; when the environmental parameter is the temperature, controlling the cooling system in the engine compartment to turn on to reduce the temperature corresponding to the target position.

[0022] In the above technical solution, the smoke concentration is usually an environmental parameter when a fire accident occurs in the vehicle. In order to deal with abnormalities in a timely manner, the present application can also intelligently turn on the fire extinguishing system in the engine compartment to extinguish the fire when the smoke concentration in the vehicle is high, thereby reducing the smoke concentration in the engine compartment; or, when the temperature in the engine compartment is high, turn on the cooling system in the engine compartment to cool down. The above process ensures that when an abnormality occurs in the vehicle, the abnormality of the vehicle is handled automatically and in a timely manner, avoiding further aggravation and spread of the abnormality, thereby ensuring the safety of the vehicle.

[0023] In summary, when the vehicle is powered on, in order to ensure and monitor the safety of the vehicle, the present 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 environment state of the engine compartment. Further, by comparing the environmental parameters with the preset conditions, when the environmental parameters meet the preset conditions, it is determined that an abnormality has occurred in the vehicle engine compartment, and the target position where the abnormality has occurred is confirmed. The target position can be the left position or 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 it is monitored that the vehicle speed is less than or equal to the preset speed, the present application can further control the target hood corresponding to the target position to open. Among them, the target hood includes a left hood corresponding to the left position, and a right hood corresponding to the right position.

[0024] The above-mentioned monitoring of the safety of the engine compartment through environmental parameters is simple, accurate and efficient. And when an abnormality occurs in the vehicle, it can humanely remind the user to be alert and deal with the abnormality of the target position in a timely manner, achieving the effect of ensuring the safety of the user in time when the user is riding in the vehicle. Finally, based on the correspondence between the target hood and the target position, the present application can also flexibly control the opening of the target hood corresponding to the target position when the vehicle speed is low. On the one hand, it achieves the flexible opening of the left hood and the right hood without interfering with each other; on the other hand, by opening the target hood, it can also achieve the effect of intelligently handling abnormalities in the vehicle.

[0025] According to the state of the engine compartment during operation, the environmental parameters of the present application include at least one of smoke concentration, temperature and noise decibel. When judging that 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. 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 parameters do not meet the preset conditions. Through the above-mentioned judgment of smoke concentration, temperature and noise decibel, it is possible to avoid fire and abnormal operation of components in the engine compartment, and effectively ensure the safety of the engine compartment.

[0026] Based on the fact that the engine hood is divided into a left hood and a right hood, the present application can separately monitor the first environmental parameter of the left position corresponding to the left hood, and the second environmental parameter of the right position corresponding to the right hood. Based on the above process, when judging that the environmental parameters meet the preset conditions, it can also be divided into two scenarios: when 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 conditions; when 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 conditions. The above-mentioned monitoring of the environmental parameters on different sides of the engine compartment can achieve the effect of subsequent separate control of the left hood and the right hood.

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

[0028] When it is determined that the vehicle has an abnormality, in order to promptly remind the user, the present application provides a triggering process for target prompt information. Specifically, the vehicle can generate target prompt information based on the target position and environmental parameters. Then the display device is further controlled to display the target prompt information, and the audio playback device is further controlled to broadcast the target prompt information. Thus, when an abnormality occurs in the engine compartment, the user can be quickly and diversely reminded based on a dual reminder method of voice reminder and text reminder, so that the user can pay attention to and handle the abnormality in time. Thus, the safety of the user's life and the safety of the vehicle are guaranteed.

[0029] When opening the target hood, the present application can provide two opening scenarios. The first 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 opening of the target hood through a variety of opening methods such as voice control (e.g., voice of "open the target hood"), click operation (e.g., selecting the "open" control of the target hood by clicking), gesture adjustment operation (e.g., making a gesture corresponding to opening the target hood), etc.

[0030] The second is the automatic opening scenario. In this scenario, no user participation is required. As long as the vehicle detects that the speed is less than or equal to the preset speed, the target hood will be automatically triggered to open.

[0031] The above two opening scenarios ensure that the opening methods of the target hood are flexible and diverse, and improve the opening efficiency of the target hood.

[0032] Smoke concentration is usually an environmental parameter when a fire accident occurs in a vehicle. In order to handle abnormalities in a timely manner, the present application can also intelligently turn on the fire extinguishing system in the engine compartment to extinguish the fire when the smoke concentration in the vehicle is high, thereby reducing the smoke concentration in the engine compartment; or, when the temperature in the engine compartment is high, turn on the cooling system in the engine compartment to cool down. The above process ensures that when an abnormality occurs in the vehicle, the abnormality of the vehicle is handled automatically and in a timely manner, avoiding further aggravation and spread of the abnormality, thereby ensuring the safety of the vehicle.

[0033] In a second aspect, a vehicle engine compartment safety control device is provided, the device comprising: an acquisition module, for acquiring environmental parameters of the engine compartment of the vehicle when the vehicle is in a powered-on state, the environmental parameters being used to represent the cabin environmental state of the engine compartment; a first determination module, for determining a target position where an abnormality occurs in the engine compartment when the environmental parameters meet preset conditions, the target position comprising a left position and a right position of the engine compartment; a trigger module, for triggering target prompt information according to the target position and the environmental parameters, the target prompt information being used to prompt that an abnormality occurs at the target position of the engine compartment; a control module, for controlling a target hood corresponding to the target position to open when the vehicle speed is less than or equal to a preset speed, the target hood comprising a left hood corresponding to the left position, and a right hood corresponding to the right position.

[0034] In combination with the second aspect, in some possible implementations, the environmental parameter includes at least one of smoke concentration, temperature and noise decibel. After obtaining the environmental parameter of the engine compartment of the vehicle, the device also includes: a second determination module, used to determine that the environmental parameter meets 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 meet 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.

[0039] In combination with the second aspect and the above-mentioned implementation methods, in some possible implementation methods, the environmental parameter includes at least one of smoke concentration and temperature.

[0048] 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.

[0049] 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.

[0050] Figure 1 It is a schematic structural diagram of a vehicle engine hood provided in an embodiment of the present application.

[0051] For example, Figure 1 As shown, an engine compartment is generally configured in the vehicle 101. The engine compartment generally includes an engine, a battery, a water tank refilling tank, a relay box, a brake booster pump, a fluid storage tank and other components related to the driving of the vehicle 101.

[0052] Correspondingly, the component used to cover the engine compartment is called an "engine hood" (also referred to as an engine cover, hereinafter referred to as "hood"). Different from a conventional integral engine hood, the engine hood provided in the embodiment of the present application can be divided into a left hood 102 and a right hood 103.

[0053] For example, the position of the user standing outside the vehicle 101 and facing the front windshield of the vehicle 101 is taken as the reference position, the hood corresponding to the left hand side of the user is called the "left hood 102", and the hood corresponding to the right hand side of the user is called the "right hood 103". Figure 1 As shown, correspondingly, the position of the engine compartment covered by the left hood 102 is called the "left side position of the engine compartment" (referred to as the "left side position"), and the position of the engine compartment covered by the right hood 103 is called the "right side position of the engine compartment" (referred to as the "right side position").

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

[0055] Generally, the left hood 102 and the right hood 103 are both in a closed state. Figure 1 When the vehicle 101 needs maintenance, the hood can be opened.

[0056] For example, when opening the hood, only the left hood 102 or only the right hood 103 may be opened. Alternatively, both the left hood 102 and the right hood 103 may be fully opened. When both the left hood 102 and the right hood 103 are fully opened, the state of the hood is as follows: Figure 1 As shown, it is "butterfly-shaped".

[0057] Based on the above-mentioned structure of the hood, the embodiment of the present application also proposes an example of how to control the hood.

[0058] Figure 2 It is a schematic diagram of a scenario for controlling a hood provided in an embodiment of the present application.

[0059] For example, Figure 2 As shown, a vehicle is usually equipped with multiple electronic control units (ECUs, also called controllers), and multiple ECUs can transmit data to each other through communication connections.

[0060] Optionally, the connection methods between multiple ECUs of a vehicle include Controller Area Network (CAN) bus connection, Local Interconnect Network (LIN) bus connection, Flex Ray bus connection, Media Oriented Systems Transport (MOST) bus connection, and Ethernet connection. Correspondingly, the communication methods between ECUs include CAN bus communication, LIN bus communication, Flex Ray bus communication, MOST bus communication, and Ethernet communication. The embodiments of this application are described using CAN communication as an example.

[0061] It should be understood that when ECUs communicate with each other via CAN, all data is transmitted in the form of CAN signals via different CAN buses in the vehicle.

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

[0063] like Figure 2 As shown, the embodiment of the present application mainly implements the control of the hood through a hood controller (hood ECU) 203.

[0064] Specifically, the vehicle body CAN bus 201 is provided with a central electronic module (CEM, also called a "domain controller") 202 and a hood ECU 203. In addition, the vehicle body CAN bus 201 is generally provided with other ECUs such as an air conditioner controller and a body control module (BCM), and each ECU on each CAN bus can be regarded as a node.

[0065] The CEM 202 can be understood as the master 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 can transmit data with the hood ECU 203 to realize the opening and closing process of the hood.

[0066] In a possible implementation, when the hood is opened, the electric self-priming lock 209 is in an unlocked state, and the electric support rod 210 can rotate forward to the fully open position. When the hood is closed, the electric self-priming lock 209 self-primes to the fully locked position, and the electric support rod 210 reverses and moves to the fully closed position.

[0067] Optionally, the hood may be at least one of a left hood and a right hood, which is not limited in the embodiment of the present application.

[0068] Optionally, the left hood and the right hood can be all controlled by the hood ECU 203. Alternatively, the left hood is controlled by the left hood ECU, and the right hood is controlled by the right hood ECU. This embodiment of the present application does not limit this. The following embodiment of the present application takes the example that the left hood and the right hood are uniformly controlled by the hood ECU 203 to introduce the control process of the hood.

[0069] In a possible implementation, when controlling the opening and closing of the hood, the user may implement it based on an in-vehicle application (Application, App) on a terminal device.

[0070] Specifically, CEM 202 can establish a communication connection with the terminal device through the vehicle's telematics box (T-Box, also known as a vehicle-mounted terminal, remote communication module, etc.) 204 and the mobile communication module in the terminal device. Alternatively, CEM 202 can establish a communication connection with the terminal device through the vehicle's Bluetooth module 206 and the Bluetooth module in the terminal device. After the terminal device and the vehicle establish a communication connection, the user can use the vehicle-mounted App on the terminal device to control the hood.

[0071] Optionally, when the vehicle establishes a communication connection with the terminal device through T-Box 204 and the mobile communication module of the terminal device, the corresponding communication method is called "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 method is called "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 the 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 voice (for example, opening the hood or closing the hood).

[0073] After receiving the user's click operation or voice output in the display interface, the terminal device can generate an opening instruction or a closing instruction, and send it to CEM202 through the mobile communication module of the terminal device and the vehicle's T-Box204. Further, CEM202 sends the opening instruction or the closing instruction to the hood ECU203, so that the hood ECU203 controls the opening or closing of the hood.

[0074] In 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 the 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 voice (for example, opening the hood or closing the hood).

[0075] After receiving the user's click operation or voice output in the display interface, the terminal device can generate an opening instruction or a closing instruction, and send it to CEM202 through the Bluetooth module of the terminal device and the Bluetooth module 206 of the vehicle. Further, CEM202 sends the opening instruction or the closing instruction to the hood ECU203, so that the hood ECU203 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 may also be connected to a multimedia controller 205 in the vehicle, so that the user may control the opening and closing of the hood through voice control or click operation.

[0077] For example, the user can input a voice, such as "open the hood" or "close the hood". The multimedia controller 205 obtains 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 also send the opening instruction or the closing instruction to the CEM 202. The CEM 202 further sends the opening instruction and the closing instruction to the hood ECU 203, so that the hood ECU 203 controls the hood to be opened or closed.

[0078] In another exemplary embodiment, 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 therein by clicking. The multimedia controller 205 generates an open instruction or a close instruction in response to the user's click operation. The multimedia controller 205 can also send the open instruction or the close instruction to the CEM 202. The CEM 202 further sends the open instruction and the close 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 may also be connected to a vehicle-mounted camera 207 in the vehicle, so that the user may control the opening and closing of the hood through gesture adjustment operations.

[0080] Optionally, the vehicle-mounted camera 207 in the embodiment of the present application may be an external camera or an internal camera.

[0081] Exemplarily, a vehicle camera 207 may be arranged around the hood of the vehicle. The CEM 202 may pre-store a preset gesture corresponding to opening the hood and a preset gesture corresponding to closing the hood. When the hood needs to be opened or closed, the user may make a preset gesture corresponding to opening the hood or a preset gesture corresponding to closing the hood based on the gesture adjustment operation. The vehicle camera 207 may obtain an image of the user's gesture adjustment operation by shooting, and send the image of the gesture adjustment operation to the CEM 202. If the CEM 202 determines through comparison that the gesture adjustment operation matches the preset gesture corresponding to opening the hood, an opening instruction is generated and sent to the hood ECU 203, so that the hood ECU 203 controls the hood to open. Alternatively, if the CEM 202 determines that the gesture adjustment operation matches the preset gesture corresponding to closing the hood, a closing instruction is generated and sent 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 may also be connected to the micro switch 208 of the hood, so that the user can change the state of the micro switch 208 by clicking to control the hood.

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

[0084] Through the above-mentioned methods, the embodiment of the present application can realize the process of flexibly opening and closing the hood.

[0085] After introducing the structure of the hood and the control process of the hood, a vehicle engine compartment safety control method provided by an embodiment of the present application is introduced below.

[0086] Figure 3 FIG. 1 is a schematic flow chart of a vehicle engine compartment safety control method provided in an embodiment of the present application. It should be understood that the method can be applied to Figure 2 The scenario shown can be applied to Figure 2 The CEM202, the hood ECU203 or any ECU in the vehicle, the following embodiment of the present application takes CEM202 as an example to introduce in detail a vehicle engine compartment safety control method provided by the embodiment of the present application.

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

[0088] 301. When the vehicle is powered on, obtain environmental parameters of the engine compartment of the vehicle, where the environmental parameters are used to represent the internal environmental state of the engine compartment.

[0089] It should be understood that the power-on state generally refers to the high-voltage system of the vehicle being activated, and when the high-voltage system of the vehicle is not activated, the vehicle cannot work. Corresponding to the power-on state is the power-off state of the vehicle, which generally refers to the high-voltage system of the vehicle being turned off.

[0090] When the vehicle is powered on, it indicates that the vehicle is in the startup state. When the vehicle is in the startup state, in order to avoid abnormalities in the engine compartment of the vehicle, which threaten the personal safety of the user, the embodiment of the present application can monitor the safety of the engine compartment by acquiring the environmental parameters of the engine compartment. Among them, the environmental parameters are used to indicate the cabin environment state of the engine compartment, such as the temperature and humidity of the engine compartment.

[0091] Optionally, the environmental parameters include at least one of smoke concentration, temperature and noise decibels in the engine compartment.

[0092] Optionally, the smoke concentration sensor includes a carbon monoxide concentration sensor, a carbon dioxide concentration sensor, a hydrogen sulfide concentration sensor, etc., which is not limited in the embodiments of the present application.

[0093] For example, when obtaining the smoke concentration in the engine compartment, CEM can collect and obtain it through the smoke concentration sensor in the engine compartment; when obtaining the temperature of the engine compartment, CEM can collect and obtain it through the temperature sensor in the engine compartment; when obtaining the noise decibels in the engine compartment, CEM can collect and obtain it through the noise sensor in the engine compartment.

[0094] Specifically, based on the structure of the engine hood in the embodiment of the present application, the first environmental parameter of the left side of the engine compartment corresponding to the left hood and the second environmental parameter of the right side of the engine compartment corresponding to the right hood can be obtained respectively. Correspondingly, the first environmental parameter includes at least one of the first smoke concentration, the first temperature and the first noise decibel, and the second environmental parameter includes at least one of the second smoke concentration, the second temperature and the second noise decibel.

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

[0096] Further, after acquiring the environmental parameters, the CEM may compare the environmental parameters with preset conditions to determine whether an abnormality occurs in the engine compartment.

[0097] In a possible implementation, when the CEM determines whether an abnormality occurs in the engine compartment according to environmental parameters, the following steps are specifically performed:

[0098] 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 meet the preset conditions;

[0099] 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, it is determined that the environmental parameters do not meet the preset conditions.

[0100] It should be understood that, generally speaking, excessive smoke concentration in the engine compartment indicates that there may be a fire in the engine compartment; excessive temperature in the engine compartment is usually caused by: a clogged air filter; excessive gap between the cylinder gasket and the cylinder liner; insufficient coolant; abnormal fan rotation, etc.; excessive noise in the engine compartment may be caused by: aging of the fuel, aging of the engine mounts, loose components in the engine compartment, clogged intake or exhaust systems, etc.

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

[0102] In the above technical solution, according to the state of the engine compartment during operation, the environmental parameters of the present application include at least one of smoke concentration, temperature and noise decibel. When judging that 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. 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 parameters do not meet the preset conditions. Through the above-mentioned judgment of smoke concentration, temperature and noise decibel, it is possible to avoid fire and abnormal operation of components in the engine compartment, and effectively ensure the safety of the engine compartment.

[0103] Specifically, based on different locations, the environmental parameters are divided into first environmental parameters and second environmental parameters. The embodiment of the present application determines that the environmental parameters meet the preset conditions, specifically including at least one of the following:

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

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

[0106] For example, assume 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 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 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 both the first environmental parameter and the second environmental parameter meet the preset condition.

[0107] In the above technical solution, based on the engine hood being divided into a left hood and a right hood, the present application can separately monitor the first environmental parameter of the left position corresponding to the left hood, and the second environmental parameter of the right position corresponding to the right hood. Based on the above process, when judging that the environmental parameters meet the preset conditions, it can also be divided into two scenarios: when 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 conditions; when 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 conditions. The above-mentioned monitoring of the environmental parameters on different sides of the engine compartment can achieve the effect of subsequently separately controlling the left hood and the right hood.

[0108] 302, when the environmental parameters meet the preset conditions, determine the target position where the abnormality occurs in the engine compartment, and the target position includes the left position and the right position of the engine compartment.

[0109] In step 301, if the CEM determines that the environmental parameters meet the preset conditions, the target position can be further determined by the environmental parameters.

[0110] In a possible implementation, when determining the target location where an abnormality occurs in the engine compartment, specifically including:

[0111] When the first environmental parameter meets the preset condition, the left position is determined as the target position;

[0112] When the second environmental parameter meets the preset condition, the right position is determined as the target position;

[0113] When the first environmental parameter meets the preset condition and the second environmental parameter meets the preset condition, the left position and the right position are determined as the target positions.

[0114] Exemplarily, assume 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 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 position as the target position. 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. Correspondingly, the CEM determines the right position as the target position. If the 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 meet the preset conditions at the same time. And the left position and the right position are correspondingly determined as the target position.

[0115] In the above technical solution, based on the above-mentioned separate monitoring process of the first environmental parameter and the second environmental parameter, there are also three corresponding scenarios when determining the target position. The first is to determine the left position as the target position when the first environmental parameter meets the preset conditions; the second is to determine the right position as the target position when the second environmental parameter meets the preset conditions; the third is to determine the left position and the right position as the target position at the same time when both the first environmental parameter and the second environmental parameter meet the preset conditions. The above process realizes the corresponding determination of different target positions according to the different types of environmental parameters, thereby ensuring the accuracy of the target position determination.

[0116] 303. According to the target position and the environmental parameters, a target prompt information is triggered, where the target prompt information is used to prompt that an abnormality occurs in the target position of the engine compartment.

[0117] After determining the target location, in order to remind the user in time, the embodiment of the present application can also trigger target prompt information based on the target location and environmental parameters. Specifically including:

[0118] Generate target prompt information according to target position and environmental parameters;

[0119] The display device of the vehicle is controlled to display the target prompt information, and the audio playback 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 be informed of the overview of the current abnormality, such as the location where the abnormality currently occurs (target location) and the cause of the abnormality (environmental parameters), so that the user can formulate a corresponding treatment plan according to the abnormality.

[0121] Therefore, when an abnormality occurs in the engine compartment of the vehicle, the CEM can first generate target prompt information according to the target position and environmental parameters, and further control the display device in the vehicle to display the target prompt information and the audio playback device to broadcast the target prompt information.

[0122] Optionally, the display device includes a multimedia host, a rear LCD screen, a display screen of a head-up display (HUD) system, an instrument panel, etc., which is not limited in the present embodiment. The present embodiment takes the multimedia host as an example for illustration.

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

[0124] In the above technical solution, when it is determined that the vehicle has an abnormality, in order to promptly remind the user, this application provides a triggering process for target prompt information. Specifically, the vehicle can generate target prompt information based on the target position and environmental parameters. Then further control the display device to display the target prompt information, and the audio playback device to broadcast the target prompt information. Thus, when an abnormality occurs in the engine compartment, based on the dual reminder method of voice reminder and text reminder, the user can be quickly and diversely reminded, so that the user can pay attention to and handle the abnormality in time. Thereby ensuring the safety of the user's life and the safety of the vehicle.

[0125] Furthermore, when an abnormality occurs in the engine compartment, in addition to reminding the user to take precautions, the embodiment of the present application also provides a method for automatically handling the abnormality.

[0126] In a possible implementation, when CEM automatically handles anomalies at a target location, specifically:

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

[0128] When the environmental parameter is temperature, the cooling system in the engine compartment is controlled to start so as to reduce the temperature corresponding to the target position.

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

[0130] Optionally, the types of fire extinguishers include aerosol fire extinguishers, dry powder fire extinguishers, ultrafine dry powder fire extinguishers, carbon dioxide fire extinguishers, water-based fire extinguishers, etc., which are not limited in the embodiments of the present application.

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

[0132] In the above technical solution, the smoke concentration is usually an environmental parameter when a fire accident occurs in the vehicle. In order to deal with abnormalities in a timely manner, the present application can also intelligently turn on the fire extinguishing system in the engine compartment to extinguish the fire when the smoke concentration in the vehicle is high, thereby reducing the smoke concentration in the engine compartment; or, when the temperature in the engine compartment is high, turn on the cooling system in the engine compartment to cool down. The above process ensures that when an abnormality occurs in the vehicle, the abnormality of the vehicle is handled automatically and in a timely manner, avoiding further aggravation and spread of the abnormality, thereby ensuring the safety of the vehicle.

[0133] 304 , when the vehicle speed is less than or equal to a preset speed, control the target hood corresponding to the target position to open, the target hood including a left hood corresponding to the left position and a right hood corresponding to the right position.

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

[0135] Specifically, when opening the target hood, the CEM may 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 of a high smoke concentration, it means that the engine compartment of the vehicle may be on fire. In this case, if the engine hood is opened, the air may fully contact the burning material to increase the fire, and in serious cases, the vehicle may explode, threatening the personal safety and property safety of people around the vehicle. Therefore, the opening of the target engine hood in the embodiment of the present application is mainly aimed at the scene of excessive temperature and excessive noise.

[0137] Furthermore, when opening the target hood, the embodiment of the present application can provide two methods, namely manual opening and automatic opening. Among them, manual opening means that the user's participation is required, and the opening of the target hood is triggered by various operations of the user; automatic opening means that the CEM directly controls the opening of the target hood without the participation of the user. The following embodiment of the present application takes the target hood as the left hood and illustrates the opening process of the target hood.

[0138] In a possible implementation, the method of automatically opening the target hood specifically includes:

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

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

[0141] For example, when CEM obtains that the current vehicle speed is 0 km / h through the instrument controller; or, CEM obtains that the vehicle speed is 0 km / h through the controller of the Anti-Lock Brake System (ABS) directly connected to the vehicle speed sensor, CEM sends a left hood opening command to the hood ECU, so that the hood ECU controls the left hood of the vehicle to open automatically.

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

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

[0144] Based on the different control methods of voice control, click operation and gesture adjustment operation, the following Figure 2 The description in , respectively, introduces in detail each control method of manually opening the target engine hood.

[0145] The first one: Voice control

[0146] For example, when the communication mode 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 the 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, such as the voice of "open the left hood".

[0147] The terminal device receives the user's voice and generates a left hood opening instruction. The instruction is sent to CEM202 through the mobile communication module of the terminal device and the vehicle's T-Box204. CEM202 further sends the left hood opening instruction to the hood ECU203, so that the hood ECU203 controls the left hood to open according to the left hood opening instruction.

[0148] In another example, when the communication mode 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 the 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, such as the voice of "open the left hood".

[0149] The terminal device receives the user's voice and generates a left hood opening instruction, and sends it to CEM202 through the Bluetooth module of the terminal device and the Bluetooth module 206 of the vehicle. CEM202 then sends the left hood opening instruction to the hood ECU203, so that the hood ECU203 controls the left hood to open according to the left hood opening instruction.

[0150] In another exemplary embodiment, the user can also control the multimedia host 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, such as the voice of "open the left hood".

[0151] The multimedia controller 205 receives the user's voice, generates a left hood opening instruction and sends it to the CEM 202. The CEM 202 further 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] For example, when the communication mode 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 the 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 clicking.

[0154] The terminal device receives the user's click operation and generates a left hood opening instruction. The instruction is sent to CEM202 through the mobile communication module of the terminal device and the vehicle's T-Box204. CEM202 further sends the left hood opening instruction to the hood ECU203, so that the hood ECU203 controls the left hood to open according to the left hood opening instruction.

[0155] In another example, when the communication mode 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 the 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 clicking.

[0156] The terminal device receives the user's voice, generates a left hood opening instruction, and sends it to CEM202 through the Bluetooth module of the terminal device and the vehicle's Bluetooth module 206. Further, CEM202 sends the left hood opening instruction to the hood ECU203, so that the hood ECU203 controls the left hood to open according to the left hood opening instruction.

[0157] In another exemplary embodiment, the user can also control the multimedia host 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 clicking.

[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. The CEM 202 further 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] In another exemplary embodiment, the user may also click the micro switch 208 of the left hood by 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. 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.

[0160] The third type: gesture adjustment operation

[0161] For example, assume that the preset gesture for opening the left hood pre-stored in CEM202 is "making a victory gesture with the right hand". Then when the user needs to open the left hood, the user can make the preset gesture. The vehicle-mounted camera 207 can capture an image of the user's gesture adjustment operation and send it to CEM202. CEM202 determines the left hood opening instruction based on the image. Then the left hood opening instruction is sent to the hood ECU203, so that the hood ECU203 controls the left hood to open.

[0162] In the above technical solution, when opening the target hood, the present application can provide two opening scenarios. The first 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 opening of the target hood through a variety of opening methods such as voice control (e.g., voice of "open the target hood"), click operation (e.g., selecting the "open" control of the target hood by clicking), gesture adjustment operation (e.g., making a gesture corresponding to opening the target hood), etc.

[0163] The second is the automatic opening scenario. In this scenario, no user participation is required. As long as the vehicle detects that the speed is less than or equal to the preset speed, the target hood will be automatically triggered to open.

[0164] The above two opening scenarios ensure that the opening methods of the target hood are flexible and diverse, and improve the opening efficiency of the target hood.

[0165] In summary, when the vehicle is powered on, in order to ensure and monitor the safety of the vehicle, the present 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 environment state of the engine compartment. Further, by comparing the environmental parameters with the preset conditions, when the environmental parameters meet the preset conditions, it is determined that an abnormality has occurred in the vehicle engine compartment, and the target position where the abnormality has occurred is confirmed. The target position can be the left position or 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 it is monitored that the vehicle speed is less than or equal to the preset speed, the present application can further control the target hood corresponding to the target position to open. Among them, the target hood includes a left hood corresponding to the left position, and a right hood corresponding to the right position.

[0166] The above-mentioned monitoring of the safety of the engine compartment through environmental parameters is simple, accurate and efficient. And when an abnormality occurs in the vehicle, it can humanely remind the user to be alert and deal with the abnormality of the target position in a timely manner, achieving the effect of ensuring the safety of the user in time when the user is riding in the vehicle. Finally, based on the correspondence between the target hood and the target position, the present application can also flexibly control the opening of the target hood corresponding to the target position when the vehicle speed is low. On the one hand, it achieves the flexible opening of the left hood and the right hood without interfering with each other; on the other hand, by opening the target hood, it can also achieve the effect of intelligently handling abnormalities in the vehicle.

[0167] According to the state of the engine compartment during operation, the environmental parameters of the present application include at least one of smoke concentration, temperature and noise decibel. When judging that 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. 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 parameters do not meet the preset conditions. Through the above-mentioned judgment of smoke concentration, temperature and noise decibel, it is possible to avoid fire and abnormal operation of components in the engine compartment, and effectively ensure the safety of the engine compartment.

[0168] Based on the fact that the engine hood is divided into a left hood and a right hood, the present application can separately monitor the first environmental parameter of the left position corresponding to the left hood, and the second environmental parameter of the right position corresponding to the right hood. Based on the above process, when judging that the environmental parameters meet the preset conditions, it can also be divided into two scenarios: when 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 conditions; when 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 conditions. The above-mentioned monitoring of the environmental parameters on different sides of the engine compartment can achieve the effect of subsequent separate control of the left hood and the right hood.

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

[0170] When it is determined that the vehicle has an abnormality, in order to promptly remind the user, the present application provides a triggering process for target prompt information. Specifically, the vehicle can generate target prompt information based on the target position and environmental parameters. Then the display device is further controlled to display the target prompt information, and the audio playback device is further controlled to broadcast the target prompt information. Thus, when an abnormality occurs in the engine compartment, the user can be quickly and diversely reminded based on a dual reminder method of voice reminder and text reminder, so that the user can pay attention to and handle the abnormality in time. Thus, the safety of the user's life and the safety of the vehicle are guaranteed.

[0171] When opening the target hood, the present application can provide two opening scenarios. The first 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 opening of the target hood through a variety of opening methods such as voice control (e.g., voice of "open the target hood"), click operation (e.g., selecting the "open" control of the target hood by clicking), gesture adjustment operation (e.g., making a gesture corresponding to opening the target hood), etc.

[0172] The second is the automatic opening scenario. In this scenario, no user participation is required. As long as the vehicle detects that the speed is less than or equal to the preset speed, the target hood will be automatically triggered to open.

[0173] The above two opening scenarios ensure that the opening methods of the target hood are flexible and diverse, and improve the opening efficiency of the target hood.

[0174] Smoke concentration is usually an environmental parameter when a fire accident occurs in a vehicle. In order to handle abnormalities in a timely manner, the present application can also intelligently turn on the fire extinguishing system in the engine compartment to extinguish the fire when the smoke concentration in the vehicle is high, thereby reducing the smoke concentration in the engine compartment; or, when the temperature in the engine compartment is high, turn on the cooling system in the engine compartment to cool down. The above process ensures that when an abnormality occurs in the vehicle, the abnormality of the vehicle is handled automatically and in a timely manner, avoiding further aggravation and spread of the abnormality, thereby ensuring the safety of the vehicle.
