[0040] 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.

[0041] 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.

[0042] Figure 1 It is a schematic diagram of a scenario of vehicle protection provided in an embodiment of the present application.

[0043] For example, Figure 1 As shown, Figure 1 The vehicle 110 includes a hood 120 and an engine compartment 130, wherein the engine compartment 130 may include a fire extinguishing device 140, and the fire extinguishing device 140 may be used to spray a fire extinguishing medium, such as a flame retardant. Also, the fire extinguishing device 140 may be symmetrically arranged on both sides of the engine compartment 130 (e.g., Figure 1 As shown in the figure), it can also be arranged in other parts of the engine compartment 130, such as the front or middle of the engine compartment 130, which is not limited to the embodiment of the present application.

[0044] In order to clearly display the engine compartment 130 and the fire extinguishing equipment 140, the engine hood 120 is in an open state (such as Figure 1 In daily use of the vehicle, the engine hood 120 may also be in a closed state.

[0045] During the use of vehicle 110, a collision may occur due to improper driving of the driver. If the collision location is the engine compartment 130, a fire may occur in the engine compartment 130 due to fuel tank leakage or falling of high-voltage wires, causing damage to vehicle 110 and posing a threat to the safety of users in and around vehicle 110.

[0046] In the related art, when a collision occurs in the engine compartment 130, the fire extinguishing equipment 140 can be controlled to spray flame retardants to extinguish the fire. However, this fire extinguishing method cannot ensure the success of the fire extinguishing, nor can it prevent the fire, which may pose a threat to the safety of the vehicle and the users in and around the vehicle.

[0047] In order to solve the above problems, the present application proposes a vehicle protection method, which is specifically described in the following content.

[0048] Figure 2 It is a system schematic diagram of the vehicle protection method provided in an embodiment of the present application.

[0049] For example, Figure 2As shown, the system 200 may include a collision sensor 210 , a collision analysis unit 220 , a body control module 230 (Body Control Module, BCM), a fire extinguishing unit 240 , a state detection unit 250 , a voice unit 260 , a headlight 270 and a horn 280 .

[0050] The collision sensor 210 can be used to detect the current pressure at any position of the engine compartment and transmit the detected current pressure to the collision analysis unit 220. The transmission method can be controller area network (CAN) bus transmission, local interconnect15 network (LIN) bus transmission, Flex Ray bus transmission, media oriented systems transport (MOST) bus transmission, Ethernet transmission, etc.

[0051] The collision analysis unit 220 may be configured to receive the current pressure transmitted by the collision sensor 210 , determine whether a collision occurs in the engine compartment based on the current pressure, and transmit the collision analysis result to the BCM 230 .

[0052] BCM 230 can be used to receive the collision analysis result transmitted by the collision analysis unit 220, and when the collision analysis result is a collision, control the fire extinguishing unit 240 to be in the activated state. Also, BCM 230 can also be used to send a detection instruction to the state detection unit 250 to detect the current state of the engine compartment when the collision analysis result is a collision. Also, when the collision analysis result is no collision, BCM 230 can be used to continuously receive the collision analysis result transmitted by the collision analysis unit 220. In addition, BCM 230 can also be used to send control instructions to the voice unit 260, the headlight 270, and the horn 280 respectively when the collision analysis result is a collision.

[0053] The fire extinguishing unit 240 may be used to spray a fire extinguishing medium to put out a fire in the engine compartment.

[0054] The state detection unit 250 may be used to detect the fire state in the engine compartment and feed back the detection result to the BCM 230 so that the BCM 230 adjusts the fire extinguishing strength of the fire extinguishing unit 240 according to the detection result.

[0055] The voice unit 260 can be used to receive the control instructions sent by the BCM 230 and give voice reminders to the user according to the control instructions, for example, "the engine compartment has collided" and "please leave the vehicle".

[0056] The vehicle light unit 270 may be used to receive control instructions sent by the BCM 230 and control the vehicle lights to flash according to the control instructions to alert users around the vehicle.

[0057] The speaker unit 280 can be used to receive control instructions sent by the BCM 230, and sound the horn according to the control instructions to remind users in the vehicle and users around the vehicle.

[0058] Figure 3 is a flow chart of a vehicle protection method provided by an embodiment of the present application. The method can be Figure 1 The vehicle 110 performs, or Figure 2 The BCM 230 in the system is executed.

[0059] For example, Figure 3 As shown, the method 300 includes the following implementation process:

[0060] S310, obtaining the power status of the vehicle.

[0061] The power state may include a power-on state and a power-off state. The power-on state means that the vehicle is powered on, the power supply voltage of the vehicle may be 12V, and the CAN network in the vehicle is in an activated state, information transmission can be performed, and the engine in the vehicle is not started. The power-off state means that the vehicle is in a power-off state, and the CAN network is in a dormant state.

[0062] Exemplarily, the current power state of the vehicle, for example, a power-on state or a power-off state, may be acquired through a power control unit in the vehicle.

[0063] S320, if the power state of the vehicle is powered on, detect whether the engine compartment of the vehicle has collided. If so, execute S330; if not, execute S310.

[0064] For example, if the current power state of the vehicle is the power-on state, it is possible to detect whether the engine compartment of the vehicle has collided. For example, the current pressure at any position in the engine compartment of the vehicle can be detected by the collision detection module, and the detected current pressure can be sent to the collision analysis unit, so that the collision analysis unit analyzes the current pressure to determine whether the engine compartment has collided.

[0065] For example, if the collision analysis unit analyzes that the current pressure is greater than or equal to the preset pressure, or the change rate of the current pressure within a fixed time period (for example, 1S or 2S) is greater than or equal to the preset change rate, it can be determined that a collision has occurred in the engine compartment and the collision analysis result can be sent to the BCM.

[0066] Optionally, if the collision analysis unit analyzes that the current pressure is less than the preset pressure, or the change rate of the current pressure within a fixed time (for example, 1S or 2S) is less than the preset change rate, it can be determined that the engine compartment has not collided. This may be because the pressure generated by the engine operation itself or the pressure generated by the body vibration caused by poor road conditions during the vehicle's driving is not the pressure generated by the collision of the engine compartment, which can avoid the fire extinguishing equipment from performing fire extinguishing when the engine compartment has not collided, causing an impact on the normal operation of the vehicle.

[0067] It should be understood that the collision of the engine compartment occurs in a short period of time, so the time for detecting the pressure change rate is set to be low to ensure accurate judgment of the collision result.

[0068] Further, if it is detected that the engine compartment has not collided, S310 may be executed. It should be understood that the implementation details of S310 are introduced in the above steps and will not be repeated here.

[0069] Furthermore, if a collision of the engine compartment is detected, S330 may be executed.

[0070] S330: If a collision is detected in the engine compartment, control the fire extinguishing equipment in the vehicle to perform a first fire extinguishing process and detect the current state of the engine compartment.

[0071] Exemplarily, the first fire extinguishing process may include the fire extinguishing equipment spraying a fire extinguishing medium into the engine compartment. The fire extinguishing medium may include water, a flame retardant, an inert gas and / or nitrogen, etc.

[0072] For example, if it is determined that the engine compartment has collided, the BCM can send a fire extinguishing instruction to the fire extinguishing equipment in the vehicle, control the fire extinguishing equipment to perform the first fire extinguishing process, and control the fire extinguishing equipment to spray a fire extinguishing medium, such as water. By performing the first fire extinguishing process when the engine compartment collides, the effect of preventing the fire in the engine compartment can be achieved, thereby avoiding the fire in the engine compartment due to the collision.

[0073] For example, if it is determined that a collision has occurred in the engine compartment, a prompt message may be sent.

[0074] The reminder information is used to remind the user that the engine compartment has collided. The reminder information can be sent in one or more of a voice reminder, a flashing light reminder, and a whistle.

[0075] For example, if it is determined that a collision has occurred in the engine compartment, a reminder message such as "a collision has occurred in the engine compartment" or "please stop the vehicle and move away from it" may be sent to the user through the voice unit in the vehicle.

[0076] For another example, if it is determined that a collision has occurred in the engine compartment, the vehicle's lighting unit can be used to control the lights to flash, thereby sending a prompt message to users around the vehicle, so that they stay away from the vehicle and are in a safe environment, and providing timely rescue to users in the vehicle.

[0077] It should be understood that the flashing of the car lights can be performed at a preset frequency. In order to attract the attention of users around the vehicle, the car lights can flash at a high frequency, for example, flashing once in 1S, or flashing twice in 1S. This embodiment of the present application is not limited to this.

[0078] Alternatively, the vehicle lights may also project a preset pattern onto the ground, such as "HEIP", "SOS" or "Help", etc., to attract the attention of users around the vehicle, so that users in the vehicle can receive timely assistance.

[0079] For another example, if the vehicle's current power state is powered on and it is determined that a collision has occurred in the engine compartment, the horn unit in the vehicle can be used to sound a horn to alert users in the vehicle and users around the vehicle, so that the users in the vehicle and users around the vehicle can move away from the colliding vehicle as soon as possible and be in a safe environment.

[0080] It should be understood that the whistle can be blew in a long manner, that is, the whistle sound is uninterrupted; or, it can be blew in a short manner, that is, the whistle is blew at a preset frequency, for example, blew once every 2S, or blew once every 3S. The embodiments of the present application are not limited to this.

[0081] For example, if the vehicle is currently powered on and the engine compartment is determined to have collided, fault information can be displayed on the vehicle's dashboard to let the driver know the current status of the engine compartment in a timely manner. Alternatively, the fire department can be automatically dialed, including the vehicle's current location and the fire status of the engine compartment, to avoid the fire in the engine compartment being too large and the fire extinguishing medium stored in the vehicle being unable to completely extinguish it, which in turn causes the entire vehicle to burn or explode.

[0082] For example, if it is determined that the engine compartment has collided, the running state of the vehicle can be obtained. Specifically, the running state of the vehicle can include a driving state and a parking state. The driving state can include that the current speed of the vehicle is greater than 0 km / h, and the parking state can include that the current speed of the vehicle is equal to 0 km / h.

[0083] For example, if it is determined that a collision has occurred in the engine compartment, the current operating state of the vehicle (driving state or parking state) may be acquired.

[0084] Further, after the current running state of the vehicle is acquired, it is determined whether the running state of the vehicle is a parking state.

[0085] For example, if it is determined that the engine compartment has collided, and it is obtained that the vehicle is not currently in a parking state (i.e., driving state), a parking instruction message can be sent to the driver, so that the driver can control the vehicle to park according to the instruction message, and the vehicle's operating state changes from the driving state to the parking state. Alternatively, if the driver does not respond to the parking instruction message within a preset time (e.g., 30S), it may be due to the collision of the engine compartment causing the driver to faint or lose the ability to move. The parking instruction message can be sent to the BCM, so that the BCM controls the vehicle to automatically park, avoiding the occurrence of a secondary accident of the vehicle, thereby effectively ensuring the safety of the vehicle, and then protecting the safety of the users in the vehicle and the users around the vehicle.

[0086] For example, if it is determined that the engine compartment has collided and the vehicle is in a parked state, the current state of the door may be detected. The current state of the door may include a locked state and an unlocked state.

[0087] Optionally, if it is determined that a collision has occurred in the engine compartment and the vehicle is parked, and it is detected that the current state of any door in the vehicle is locked, the door can be controlled to be unlocked, even if the current state of the door changes from a locked state to an unlocked state, thereby providing an escape route for users in the vehicle and ensuring that users in the vehicle can be rescued smoothly.

[0088] Optionally, if it is determined that a collision has occurred in the engine compartment and the vehicle is in a parked state, and it is detected that the current states of the doors in the vehicle are all unlocked, the current states of the doors are not controlled, so that the doors remain unlocked.

[0089] Optionally, if it is determined that a collision occurs in the engine compartment, the current state of the engine compartment may be detected simultaneously so as to adjust the fire extinguishing intensity of the fire extinguishing treatment according to the current state of the engine compartment.

[0090] Exemplarily, it is detected whether there is smoke in the engine compartment, and / or it is detected whether the current temperature of the engine compartment is greater than a preset temperature threshold.

[0091] Among them, since the temperature in the engine compartment is generally between 70°C and 90°C, in order to avoid the temperature in the engine compartment rising during a fire and errors caused by detection, the preset temperature threshold can be set to 95°C or 98°C. It should be understood that the setting of the preset temperature threshold is also related to the vehicle's driving time, driving distance, driving speed and current weather temperature. The preset temperature threshold can be adaptively adjusted by the BCM according to the vehicle's driving time, driving distance, driving speed and current weather temperature, and the embodiments of the present application do not limit this.

[0092] Optionally, a smoke sensor arranged in the engine compartment can be used to detect whether smoke currently exists in the engine compartment, and / or a temperature sensor arranged in the engine compartment can be used to detect whether the current temperature of the engine compartment is greater than a preset temperature threshold, for example, 98°C.

[0093] In an embodiment of the present application, by detecting whether there is smoke in the engine compartment and / or detecting whether the current temperature of the engine compartment is greater than a preset temperature threshold, it is possible to accurately determine whether the engine compartment is currently in a fire state.

[0094] Further, if the smoke sensor detects smoke in the engine compartment, it means that the engine compartment may be on fire. And / or, if the temperature sensor detects that the current temperature in the engine compartment is 105° C., which is greater than 98° C., it means that the engine compartment may be on fire.

[0095] Optionally, the current state of the engine compartment can be detected by an image acquisition unit (e.g., a camera) in the engine compartment. When a collision occurs in the engine compartment, the engine compartment can be photographed by the camera in the engine compartment to acquire a current image of the engine compartment, and the current image can be transmitted to an image processing unit in the vehicle. The image processing unit can perform intelligent recognition on the acquired current image to determine whether the engine compartment is on fire. If the features of flames are identified in the current image, it can be determined that the engine compartment is on fire; if the features of flames are not identified in the current image, it can be determined that the engine compartment is not on fire.

[0096] It should be understood that the current image of the engine compartment may be collected periodically, so as to monitor the status of the engine compartment in real time and avoid accidental fire.

[0097] S340: If it is detected that the current state of the engine compartment is a fire state, control the fire extinguishing equipment to perform a second fire extinguishing process.

[0098] Among them, the fire extinguishing intensity of the second fire extinguishing treatment is greater than the fire extinguishing intensity of the first fire extinguishing treatment. It should be understood that the fire extinguishing intensity can refer to the length of time required for the fire extinguishing equipment to extinguish the fire source by spraying the fire extinguishing medium for the same fire source; the fire extinguishing intensity of the second fire extinguishing treatment is greater than the fire extinguishing intensity of the first fire extinguishing treatment, which can mean that the time required for the second fire extinguishing treatment to extinguish the fire source is less than the time required for the first fire extinguishing treatment to extinguish the same fire source; that is, it can be understood that the fire extinguishing intensity (or, fire extinguishing efficiency) of the second fire extinguishing treatment is greater than the fire extinguishing intensity (or, fire extinguishing efficiency) of the first fire extinguishing treatment. In other words, the fire extinguishing intensity of the second fire extinguishing treatment is greater than the fire extinguishing intensity of the first fire extinguishing treatment, that is, the fire extinguishing effect of the second fire extinguishing treatment is better than the fire extinguishing effect of the first fire extinguishing treatment.

[0099] Optionally, the first fire extinguishing process may include the fire extinguishing equipment spraying a fire extinguishing medium into the engine compartment, and the second fire extinguishing process may also include the fire extinguishing equipment spraying a fire extinguishing medium into the engine compartment. The fire extinguishing medium sprayed into the engine compartment by the fire extinguishing equipment in the first fire extinguishing process and the second fire extinguishing process may be the same or different.

[0100] Exemplarily, the fire extinguishing strength of the second fire extinguishing process is greater than the fire extinguishing strength of the first fire extinguishing process, including the following implementations:

[0101] The first method: the injection amount of the fire extinguishing medium injected in the second fire extinguishing treatment is greater than the injection amount of the fire extinguishing medium injected in the first fire extinguishing treatment.

[0102] For example, the amount of water sprayed by the fire extinguishing equipment in the second fire extinguishing process (eg, 1 kg sprayed in 2S) is greater than the amount of water sprayed by the fire extinguishing equipment in the first fire extinguishing process (eg, 1 kg sprayed in 2S).

[0103] The second method: the spraying frequency of the fire extinguishing medium in the second fire extinguishing treatment is greater than the spraying frequency of the fire extinguishing medium in the first fire extinguishing treatment.

[0104] For example, the spraying frequency of the fire extinguishing equipment spraying water in the second fire extinguishing process (eg, 0.5 kg spraying in 1S) is greater than the spraying frequency of the fire extinguishing equipment spraying water in the first fire extinguishing process (eg, 0.5 kg spraying in 2S).

[0105] The third method: the first fire extinguishing treatment sprays the first fire extinguishing medium in the fire extinguishing medium, and the second fire extinguishing treatment sprays the second fire extinguishing medium in the fire extinguishing medium, wherein the fire extinguishing strength of the second fire extinguishing medium is greater than the fire extinguishing strength of the first fire extinguishing medium.

[0106] For example, the first fire extinguishing medium is carbon dioxide, and the second fire extinguishing medium is water; the first fire extinguishing treatment sprays the fire extinguishing medium carbon dioxide, and the second fire extinguishing treatment sprays the fire extinguishing medium water. Since carbon dioxide is easy to diffuse in the air, it may not be able to accumulate enough to cover the fire source, resulting in a reduced fire extinguishing effect, that is, the fire extinguishing power of carbon dioxide is less than that of water, and the fire extinguishing effect of water is better than that of nitrogen. However, since carbon dioxide will not damage the parts in the engine compartment when extinguishing a fire, carbon dioxide can be used in the fire prevention stage to prevent the engine compartment from catching fire. It should be understood that the first fire extinguishing medium and the second fire extinguishing medium can both be used as media for fire extinguishing treatment, and the fire extinguishing power of the second fire extinguishing medium is greater than the fire extinguishing power of the first fire extinguishing medium; and the injection amount and injection frequency of the fire extinguishing medium can be set according to the vehicle model and temperature, and the embodiments of the present application are not limited to this.

[0107] Optionally, when the fire extinguishing media are different, for example, the first fire extinguishing medium is carbon dioxide and the second fire extinguishing medium is water, the fire extinguishing strength of the second fire extinguishing treatment can be further improved by increasing the injection amount and injection frequency of the second fire extinguishing medium.

[0108] For example, the amount of water sprayed by the fire extinguishing equipment in the second fire extinguishing process (e.g., 1 kg sprayed in 2S) is greater than the amount of carbon dioxide sprayed by the fire extinguishing equipment in the first fire extinguishing process (e.g., 254.5 L sprayed in 2S). It should be understood that under standard conditions, the volume of 0.5 kg of carbon dioxide is approximately: 500×22.4 / 44=254.5 L.

[0109] For another example, the spraying frequency of water sprayed by the fire extinguishing equipment in the second fire extinguishing process (eg, 0.5 kg sprayed in 1S) is greater than the spraying frequency of carbon dioxide sprayed by the fire extinguishing equipment in the first fire extinguishing process (eg, 254.5 L sprayed in 2S).

[0110] It should be understood that the first method, the second method and the third method are in an and / or relationship; that is, the injection frequency of the fire extinguishing medium sprayed by the second fire extinguishing treatment is greater than the injection frequency of the fire extinguishing medium sprayed by the first fire extinguishing treatment; and / or, the injection frequency of the fire extinguishing medium sprayed by the second fire extinguishing treatment is greater than the injection frequency of the fire extinguishing medium sprayed by the first fire extinguishing treatment; and / or, the first fire extinguishing treatment sprays the first fire extinguishing medium in the fire extinguishing medium, and the second fire extinguishing treatment sprays the second fire extinguishing medium in the fire extinguishing medium, wherein the fire extinguishing intensity of the second fire extinguishing medium is greater than the fire extinguishing intensity of the first fire extinguishing medium.

[0111] For example, when a collision occurs in the engine compartment and it is detected that the current state of the engine compartment is a fire state, the fire extinguishing equipment can be controlled to perform a second fire extinguishing treatment, i.e., increasing the injection amount and / or injection frequency of the fire extinguishing medium, and / or replacing the fire extinguishing medium with a stronger fire extinguishing force, thereby improving the fire extinguishing effect on the engine compartment and protecting users in and around the vehicle.

[0112] Optionally, when a collision occurs in the engine compartment, if it is detected that there is smoke in the engine compartment and / or the current temperature of the engine compartment is greater than a preset temperature threshold, the fire extinguishing equipment can be controlled to perform a second fire extinguishing process to improve the fire extinguishing effect on the engine compartment.

[0113] exist Figure 3In the method 300 shown, when the vehicle power supply is in the power-on state and a collision is detected in the engine compartment, two fire extinguishing strategies are provided; on the one hand, if a collision is detected in the engine compartment, the fire extinguishing equipment in the vehicle is controlled to perform a first fire extinguishing process, and the current state of the engine compartment is detected; that is, when the engine compartment collides, the fire extinguishing process is directly performed, which can avoid the engine compartment from catching fire due to the collision, thereby preventing the engine compartment from catching fire when the engine compartment collides; on the other hand, if the current state of the engine compartment is detected to be a fire state, the fire extinguishing equipment is controlled to perform a second fire extinguishing process, wherein the fire extinguishing force of the second fire extinguishing process is greater than the fire extinguishing force of the first fire extinguishing process; that is, when the engine compartment collides, the current state of the engine compartment is detected, and when the engine is detected to be on fire, the fire extinguishing force of the fire extinguishing process is increased, thereby improving the fire extinguishing efficiency and extinguishing the fire source in the engine compartment as soon as possible. Through the two-sided fire extinguishing strategies, the vehicle can be protected, and then the users in the vehicle and the users around the vehicle can be protected, and the loss caused to the vehicle by the engine compartment fire can also be reduced.

[0114] In one implementation, the above-mentioned method for protecting a vehicle may also be applied to a butterfly hood; for example, Figure 4 As shown; Figure 4 It is a schematic diagram of a butterfly-opening hood provided in an embodiment of the present application.

[0115] For example, Figure 4 As shown, the vehicle 110 may include a first hood 420, a first cabin 430, a second hood 440, a second cabin 450 and a crossbeam 460. The crossbeam 460 is between the first hood 420 and the second hood 440, and the cabin portion corresponding to the crossbeam 460 may be used as a third cabin.

[0116] Exemplarily, if a collision is detected in the first cabin, the fire extinguishing equipment may be controlled to perform a first fire extinguishing process on the first cabin, but not on the second cabin; and the current state of the first cabin may be detected.

[0117] Furthermore, if it is detected that the current state of the first cabin is a fire state, the fire extinguishing equipment may be controlled to perform a second fire extinguishing process on the first cabin.

[0118] Optionally, if a collision or fire is detected in the third cabin, the location where the collision or fire occurred in the third cabin can be detected to determine whether the location of the collision or fire is close to the first cabin or the second cabin; for example, if the location of the collision or fire is close to the first cabin, the fire extinguishing equipment can be controlled to perform the first fire extinguishing treatment on the first cabin, and not perform the first fire extinguishing treatment on the second cabin; or, if the location of the collision or fire is close to the second cabin, the fire extinguishing equipment can be controlled to perform the first fire extinguishing treatment on the second cabin, and not perform the first fire extinguishing treatment on the first cabin; or, if the location of the collision or fire is the same distance from the first cabin and the second cabin, the fire extinguishing equipment can be controlled to perform the first fire extinguishing treatment on the first cabin and the second cabin at the same time.

[0119] Optionally, while performing the first fire extinguishing treatment or the second fire extinguishing treatment on the first cabin, the current status of the second cabin can also be monitored to prevent a fire in the second cabin caused by a fire in the first cabin; if a fire in the first cabin causes a fire in the second cabin, the fire extinguishing equipment can be controlled to perform the second fire extinguishing treatment on the second cabin as well.

[0120] By detecting the position where the first engine compartment and the second engine compartment collide, and accurately spraying the fire extinguishing medium to the collision area (for example, the first engine compartment) according to the detection result, the accuracy of the fire extinguishing equipment in extinguishing the engine compartment fire is improved.

[0121] Figure 5 is a flow chart of another vehicle protection method provided by an embodiment of the present application. The method can be Figure 1 The vehicle 110 performs, or Figure 2 The BCM 230 in the system is executed.

[0122] For example, Figure 5 As shown, the method 500 includes the following implementation process:

[0123] S501, obtaining the power status of the vehicle.

[0124] S502, if the power state of the vehicle is powered on, detect whether the engine compartment of the vehicle has collided. If so, execute S503; if not, execute S501.

[0125] Exemplarily, if the power state of the vehicle is powered on and it is detected that the engine compartment of the vehicle has not collided, S501 may be executed.

[0126] For example, if the power state of the vehicle is in the power-on state and a collision is detected in the engine compartment of the vehicle, S503 may be executed.

[0127] S503, controlling the fire extinguishing equipment in the engine compartment to perform a first fire extinguishing process.

[0128] Exemplarily, if the power state of the vehicle is in the power-on state and a collision is detected in the engine compartment of the vehicle, the fire extinguishing equipment in the engine compartment can be controlled to perform a first fire extinguishing process.

[0129] It should be understood that S501 corresponds to Figure 3 S310, S502 correspond to Figure 3 S320 in, and S503 corresponding Figure 3 Part of S330, S501, S502, and S503 are already in Figure 3 The corresponding steps are introduced and will not be repeated here.

[0130] S504, obtaining the current smoke status and / or temperature status of the engine compartment.

[0131] For example, if a collision is detected in the engine compartment of the vehicle, the current smoke state and / or temperature state of the engine compartment may be acquired.

[0132] S505, detecting whether there is smoke in the engine compartment. And / or, S506, detecting whether the current temperature of the engine compartment is greater than a preset temperature threshold. If so, executing S507; if not, executing S504.

[0133] Exemplarily, if it is detected that there is no smoke in the engine compartment currently, and / or if it is detected whether the current temperature of the engine compartment is less than or equal to a preset temperature threshold, S504 may be executed.

[0134] For example, if it is detected that there is smoke in the engine compartment, and / or if it is detected whether the current temperature of the engine compartment is greater than a preset temperature threshold, S507 may be executed.

[0135] S507, controlling the fire extinguishing equipment in the vehicle to perform a second fire extinguishing process.

[0136] For example, if it is detected that there is currently smoke in the engine compartment, and / or if it is detected that the current temperature of the engine compartment is greater than a preset temperature threshold, the fire extinguishing equipment in the vehicle can be controlled to perform a second fire extinguishing process.

[0137] It should be understood that S505 and S506 are Figure 3 The various implementations of some of the contents in S330 have been Figure 3 The corresponding steps are introduced, and S507 corresponds to Figure 3 The S340 in the Figure 3 The corresponding steps are introduced and will not be repeated here.

[0138] It should also be understood that the execution order of S505 and S506 is an and / or relationship, that is, S505 and S506 can be as follows: Figure 5 The steps may be performed simultaneously or separately, which is not limited in the embodiments of the present application.

[0139] For example, if it can be determined through S502 that the engine compartment has collided, S508 and S509 can also be executed.

[0140] S508, sending reminder information.

[0141] For example, if it is determined that the engine compartment has collided, a reminder message of "engine compartment has collided" or "please stop the vehicle and move away" can be sent to the user through the voice unit in the vehicle. Alternatively, the vehicle light unit can be used to control the vehicle lights to flash to send reminder information to users around the vehicle; or the horn unit in the vehicle can be used to honk to remind users in the vehicle and users around the vehicle; or the fault information can be displayed on the vehicle dashboard to enable the driver to know the current status of the engine compartment in a timely manner.

[0142] S509, obtaining the running status of the vehicle.

[0143] For example, if it is determined that a collision occurs in the engine compartment, the current operating state of the vehicle may be acquired, for example, a driving state or a parking state.

[0144] Further, after the current operating status of the vehicle is acquired, S510 may be executed.

[0145] S510, determining whether the vehicle is in a parking state. If so, executing S512; if not, executing S511.

[0146] For example, if it is determined that a collision occurs in the engine compartment and it is obtained that the operating state of the vehicle is not a parking state (ie, a driving state), S511 may be executed.

[0147] S511, control the vehicle to stop.

[0148] For example, if it is determined that the engine compartment has collided, and the vehicle's operating state is not a parking state, that is, the vehicle's operating state is a driving state, a parking instruction message may be sent to the driver, so that the driver controls the vehicle to park according to the instruction message, and the vehicle's operating state changes from a driving state to a parking state. Alternatively, if the driver does not respond to the parking instruction message within a preset time (for example, 30 seconds), the parking instruction message may be sent to the BCM, so that the BCM controls the vehicle to automatically park.

[0149] For example, if it is determined that a collision occurs in the engine compartment and the operating state of the vehicle is obtained to be a parking state, S512 may be executed.

[0150] S512, detecting the current state of the vehicle door.

[0151] For example, if it is determined that a collision occurs in the engine compartment and the vehicle is parked, the current state of the vehicle door may be detected.

[0152] S513, determine whether the current state of the door is locked. If yes, execute S514.

[0153] For example, if it is determined that a collision occurs in the engine compartment and the vehicle is in a parked state, and it is detected that the current state of any door in the vehicle is a locked state, S514 may be executed.

[0154] For example, if it is determined that a collision occurs in the engine compartment and the vehicle is in a parked state, and it is detected that each door in the vehicle is in an unlocked state, the current state of the door is not controlled, so that the door remains unlocked.

[0155] S514, controlling the vehicle door to unlock.

[0156] For example, if it is determined that a collision has occurred in the engine compartment and the vehicle is parked, and it is detected that the current state of any door in the vehicle is locked, the door can be controlled to be unlocked, even if the current state of the door changes from a locked state to an unlocked state.

[0157] It should be understood that the execution order of S503, S504, S508 and S509 is an and / or relationship, that is, S503, S504, S508 and S509 can be as follows: Figure 5 The steps S503, S504, S508 and S509 may be executed simultaneously as shown, or they may be executed separately in the order of S503, S504, S508 and S509, which is not limited in the embodiment of the present application.
