[0027] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0028] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0029] According to an embodiment of the present invention, a collision protection method for vehicles is provided.

[0030] As an optional implementation, the above-described vehicle collision protection method can be applied, but is not limited to, the application scenario shown in Figure 1(a). Figure 1(a) is a schematic diagram of an application scenario of a vehicle collision protection method according to an embodiment of the present invention. As shown in Figure 1(a), in the application scenario, the mobile terminal 10 can communicate with the server 13 via the network 11, but is not limited to. The server 13 can perform operations on the database, such as writing data or reading data. The server can be used to perform: step S102, obtaining the scene where the vehicle is located at the current moment; step S104, detecting a collision signal in response to the scene being the target scene; step S106, in response to the detection of the collision signal, cutting off the high-voltage circuit of the vehicle through the vehicle's protection device, and sending a fault signal to the vehicle's second control device through the vehicle's first control device; and step S108, in response to the current state of the high-voltage circuit being cut off, outputting an abnormal prompt message using the collision signal and the fault signal.

[0031] The aforementioned mobile terminal 10 can be a terminal device, which may include, but is not limited to, a human-computer interaction screen, a processor, and a memory. The aforementioned human-computer interaction screen may, but is not limited to, display a virtual machine on the mobile terminal 10. The vehicle 12 may, but is not limited to, respond to the aforementioned human-computer interaction operations, execute corresponding operations, or generate corresponding instructions and send the generated instructions to the server 13. It should be noted that the steps shown in the flowcharts of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and although a logical order is shown in the flowcharts, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0032] For example, the vehicle collision protection method in this application can be used to provide collision protection functions for vehicles in different preset application scenarios. These preset application scenarios can include the following scenarios in the vehicle field: autonomous driving scenarios for commuting, artificial intelligence (AI) assisted driving scenarios for family cars, automatic parking assistance (APA) scenarios (such as memory parking for self-owned parking spaces in garages, intelligent parking for designated parking spaces in parking lots, etc.), and intelligent navigation assistance (NGP) scenarios in urban or highway areas. Furthermore, the above preset application scenarios may also include, but are not limited to: intelligent transportation scenarios for intelligent driving trucks or unmanned trucks in the logistics and transportation field, and intelligent farming scenarios for autonomous agricultural vehicles in the agricultural machinery field.

[0033] When the aforementioned preset application scenario is a scenario in a field other than the vehicle field, those skilled in the art should understand that the vehicle in the above-mentioned vehicle collision protection method can be replaced with other objects (e.g., agricultural machinery, drones, and robots), and correspondingly, the various devices and systems included in the vehicle can be replaced with devices and systems related to other objects. Based on this, this application embodiment takes the vehicle field as an example to illustrate the specific implementation of the above-mentioned vehicle collision protection method.

[0034] Figure 1(b) is a flowchart of a vehicle collision protection method according to an embodiment of the present invention. As shown in Figure 1(b), the method may include the following steps:

[0035] Step S112: Obtain the scene where the vehicle is located at the current moment.

[0036] In the technical solution provided by step S112 of the present invention, the scenario may include a target scenario and a non-target scenario. The target scenario can be a scenario where the probability of a vehicle colliding with another object is higher than or equal to a preset probability, and the non-target scenario can be a scenario where the probability of a vehicle colliding with another object is lower than the preset probability. The preset probability can be adjusted according to the type of vehicle. For example, the preset probability can be, but is not limited to, 75% and 80%.

[0037] In this embodiment, the scene in which the vehicle is located at the current moment is obtained. Optionally, this embodiment can obtain the scene in which the vehicle is located at the current moment by performing scene analysis on the scene image of the vehicle. The scene image can be acquired by a data acquisition device deployed outside the vehicle, and the data acquisition device can include infrared imagers and camera devices, etc.

[0038] Step S114: In response to the scenario being the target scenario, a collision signal is detected. The target scenario is a scenario where the probability of a vehicle colliding with other objects is higher than or equal to a preset probability. The collision signal is used to indicate that the vehicle has collided with other objects, and other objects are objects other than the vehicle.

[0039] In the technical solution provided by step S114 of the present invention, the target scenario can be a scenario in which the probability of a vehicle colliding with other objects is higher than or equal to a preset probability. For example, the target scenario can be a collision scenario.

[0040] In this embodiment, the collision signal can be used to indicate that the vehicle has collided with another object. For example, the collision signal can be of different types, including a first type of collision signal and a second type of collision signal. The first type of collision signal can represent a collision signal sent by a first control device to a protection device via a hardwired connection, and the second type of collision signal can represent a collision signal sent by the first control device to a second control device via a network, which can be a Controller Area Network (CAN).

[0041] In this embodiment, the aforementioned other objects can be objects other than vehicles. For example, the aforementioned other objects may include any one or a combination of the following objects: pedestrians, guardrails, falling rocks, motor vehicles and non-motor vehicles, etc., which are only illustrative examples and are not specifically limited.

[0042] In this embodiment, a collision signal is detected in response to the scenario being the target scenario. Optionally, this embodiment identifies the scenario in which the vehicle is located at the current moment, and obtains an identification result. This identification result can be used to represent the relationship between the aforementioned scenario and different types of scenarios, and different types of scenarios may include the target scenario. If the obtained identification result indicates that the aforementioned scenario is the target scenario, then the collision signal can be detected through the vehicle's third control device. For example, the aforementioned third control device can be an airbag controller based on a Supplemental Restraint System (SRS).

[0043] Optionally, if the identification result indicates that the scenario is another scenario, then the collision signal cannot be detected by the vehicle's third control device. The system continues to monitor the scenario in which the vehicle will be located at future moments, identifying the scenario in which the vehicle will be located at future moments until the identification result indicates that the scenario in which the vehicle will be located at future moments is the target scenario. Then, the collision signal can be detected using the third control device. Here, "future moments" can include any moment after the current moment, and "other scenarios" can be used to represent scenarios of different types other than the target scenario.

[0044] Step S116: In response to the detection of a collision signal, the high-voltage circuit of the vehicle is cut off by the vehicle's protection device, and a fault signal is sent to the vehicle's second control device by the vehicle's first control device. The connection between the protection device and the first control device on the high-voltage circuit is an electrical connection, and the connection between the first control device and the second control device is a wireless connection. The fault signal is obtained by converting the collision signal.

[0045] In the technical solution provided by step S116 of the present invention, the connection between the protection device and the first control device on the high-voltage circuit can be an electrical connection. For example, the protection device may include a smart fuse, the first control device may include a battery controller, and the electrical connection may include a hard-wired connection.

[0046] In this embodiment, the connection between the first control device and the second control device can be a wireless connection. For example, the second control device may include a vehicle controller, and the wireless connection may include a CAN communication connection.

[0047] In this embodiment, the aforementioned fault signal can be obtained by converting a collision signal. For example, the detected collision signal can be format-converted, and the format-converted collision signal can be combined with a collision severity signal to obtain the fault signal. The severity signal can be used to indicate the severity of a collision between the vehicle and other objects.

[0048] In this embodiment, after detecting a collision signal in response to the target scenario, the vehicle's high-voltage circuit is cut off via the vehicle's protection device, and a fault signal is sent from the vehicle's first control device to the vehicle's second control device. Optionally, in this embodiment, based on the detection of a collision signal, if a collision signal is detected, the vehicle's high-voltage circuit is cut off using the aforementioned protection device; the collision signal is converted using the aforementioned first control device to obtain a fault signal; and then, the converted fault signal is sent from the first control device to the aforementioned second control device.

[0049] In step S118, in response to the current state of the high-voltage circuit being disconnected, an abnormality warning message is output using the collision signal and the fault signal. The abnormality warning message is used to indicate that the vehicle has collided with other objects.

[0050] In the technical solution provided by step S118 of the present invention, the above-mentioned abnormality warning information can be used to indicate that the vehicle has collided with other objects. For example, if the other object is a motor vehicle, the above-mentioned abnormality warning information can be used to indicate that the vehicle has collided with another motor vehicle. This is only an example and is not specifically limited.

[0051] In this embodiment, after the vehicle's high-voltage circuit is disconnected via the vehicle's protection device in response to a detected collision signal, and a fault signal is sent from the vehicle's first control device to the vehicle's second control device, an abnormality alert is output based on the collision signal and the fault signal, assuming the current state of the high-voltage circuit is disconnected. Optionally, this embodiment detects the current state of the high-voltage circuit based on the disconnection operation and the sending of the fault signal to the second control device, obtaining a detection result. This detection result can be used to represent the relationship between the current state of the high-voltage circuit and the disconnected state. If the obtained detection result indicates that the current state of the high-voltage circuit is disconnected, an abnormality alert can be output using the collision signal and the fault signal.

[0052] Optionally, if the above detection results indicate that the current state of the high-voltage circuit is not disconnected, the high-voltage circuit of the vehicle is disconnected again using the redundant protection device so that the current state of the high-voltage circuit is disconnected. In this case, the above collision signal and the above fault signal can be used to output abnormal prompt information, thereby achieving the purpose of prompting the vehicle to collide with other objects.

[0053] For example, the aforementioned abnormality warning information can be displayed in the following forms: text, sound, and light. For instance, the abnormality warning information can be displayed in both text and light forms on the vehicle's central control screen; the abnormality warning information can be played as sound on the vehicle's playback device; and the abnormality warning information can be displayed as light and played as sound on the exterior of the vehicle.

[0054] It should be noted that the above-described method for outputting abnormal prompt information is merely an example and is not intended to impose specific limitations. Any process or method that can output abnormal prompt information using collision signals and fault signals, based on the detection of a collision signal, the vehicle's protection device cutting off the vehicle's high-voltage circuit, and the vehicle's first control device sending a fault signal to the vehicle's second control device, is within the protection scope of this application's embodiments, and will not be described in detail here.

[0055] The vehicle collision protection method in this application embodiment can also be applied to at least the following scenarios: autonomous driving scenario, assisted driving scenario, and passive driving scenario (which can be simply referred to as human-driven scenario). Specifically, the autonomous driving scenario can be used to describe a scenario where the vehicle's control system controls the vehicle's driving during driving, and the driver does not need to maintain control or supervision of the driving; the assisted driving scenario can be used to describe a scenario where the vehicle's control system provides auxiliary functions during driving, but the driver still needs to maintain control and supervision of the driving; and the passive driving scenario can be used to describe a scenario where the driver controls the vehicle to complete driving operations.

[0056] In AI-powered assisted driving systems for autonomous vehicles, the commuter mode typically refers to a driving mode designed specifically for commuting to and from get off work or daily commutes. The AI-powered assisted driver collects data by learning the user's driving routes and behaviors. Once the learning process is complete, the collected data is filtered and checked, and then automatically uploaded to a cloud server to construct a cloud-based map. The next time the user chooses the same route, the AI-powered assisted driver is activated, and the vehicle is driven to its destination according to the constructed cloud map. Matching and complementing offline maps with the constructed cloud map improves the accuracy of the cloud map.

[0057] In steps S112 to S118 of this application, when performing collision protection on a vehicle, a collision signal can be detected based on the target scenario where the vehicle is currently located. Upon detecting the collision signal, the vehicle's high-voltage circuit is cut off via the vehicle's protection device, and a fault signal is sent from the vehicle's first control device to its second control device. If the current state of the high-voltage circuit is cut off, an abnormality alert is output using the collision signal and the fault signal. In this embodiment, upon detecting a collision signal, the high-voltage circuit is cut off via the protection device, and a fault signal is sent from the first control device to the second control device. Furthermore, if the current state of the high-voltage circuit is cut off, an abnormality alert can be output using the collision signal and the fault signal. This achieves the goal of timely protection for vehicles involved in collisions, thus solving the technical problem of low safety in vehicle collision protection and ultimately improving the safety of vehicle collision protection.

[0058] The method described in this embodiment will be further described below.

[0059] As an optional embodiment, step S116, in response to detecting a collision signal, involves cutting off the high-voltage circuit of the vehicle through the vehicle's protection device, including: cutting off the high-voltage circuit through the protection device when the collision signal is a first type collision signal, wherein the first type collision signal is used to represent a collision signal sent by the first control device to the protection device via a hard wire.

[0060] In this embodiment, the aforementioned first type of collision signal can be used to represent a collision signal sent by the first control device to the protection device via a hardwire. For example, the aforementioned first type of collision signal can be a collision signal sent by the battery controller to the smart fuse via a hardwire, and the type of this collision signal is a hardwire signal.

[0061] In this embodiment, in response to the vehicle's current location as the target scenario, after detecting a collision signal, if the collision signal is a first-type collision signal, the high-voltage circuit is disconnected via a protection device. Optionally, based on the detected collision signal, this embodiment further determines the type of the detected collision signal. If the detected collision signal is determined to be a first-type collision signal, the high-voltage circuit is disconnected via a protection device; for example, a smart fuse can be used to disconnect the high-voltage circuit, thereby achieving the goal of disconnecting the high-voltage circuit and improving the efficiency of high-voltage power outage.

[0062] The method for outputting abnormal prompt information using collision signals and fault signals described in this embodiment will be further explained below.

[0063] As an optional embodiment, step S118, using the collision signal and the fault signal, outputs abnormal prompt information, including: when the collision signal is a second type of collision signal, using the second type of collision signal and the fault signal, outputting a first abnormal prompt information and a second abnormal prompt information, wherein the second type of collision signal is used to represent a collision signal sent by the first control device to the second control device via the network, the first abnormal prompt information is used to prompt the vehicle to collide with other objects inside the vehicle, and the second abnormal prompt information is used to prompt the vehicle to collide with other objects outside the vehicle.

[0064] In this embodiment, the aforementioned second type of collision signal can be used to represent a collision signal sent by the first control device to the second control device via a network. For example, the aforementioned second type of collision signal can be used to represent a collision signal sent by the battery controller to the vehicle controller via a CAN network, and the type of this collision signal is a CAN communication signal.

[0065] In this embodiment, the aforementioned first abnormality warning information can be used inside the vehicle to indicate that the vehicle has collided with another object. For example, if the other object is a motor vehicle, the aforementioned first abnormality warning information can be used inside the vehicle to indicate that the vehicle has collided with a motor vehicle. This is only an example and is not a specific limitation.

[0066] In this embodiment, the aforementioned second abnormality warning information can be used externally to indicate that the vehicle has collided with another object. For example, if the other object is a non-motorized vehicle, the aforementioned second abnormality warning information can be used internally to indicate that the vehicle has collided with a non-motorized vehicle. This is merely an example and is not intended to be specific.

[0067] In this embodiment, in response to a detected collision signal, after the vehicle's protection device cuts off the vehicle's high-voltage circuit and the vehicle's first control device sends a fault signal to the vehicle's second control device, if the collision signal is a second-type collision signal, a first abnormality warning message and a second abnormality warning message are output using the second-type collision signal and the fault signal. Optionally, this embodiment, based on cutting off the vehicle's high-voltage circuit and sending a fault signal to the second control device, detects the current state of the high-voltage circuit; if the detection result indicates that the current state of the high-voltage circuit is cut off, the detected collision signal is type-determined; if the detected collision signal is determined to be a second-type collision signal, the first abnormality warning message and the second abnormality warning message can be output using the second-type collision signal and the fault signal, thereby achieving the purpose of alerting the vehicle to a collision with other objects, and thus achieving the technical effect of improving the safety of vehicle collision protection.

[0068] Optionally, collision analysis of the second type of collision signal can obtain the location and time of the collision between the vehicle and other objects; fault analysis of the fault signal can obtain the severity of the collision between the vehicle and other objects; according to the location and time of the collision and the severity of the collision, a first abnormality warning message and a second abnormality warning message can be output, thereby achieving the purpose of prompting the vehicle to collide with other objects, and thus realizing the technical effect of improving the safety of vehicle collision protection.

[0069] The method described above for outputting a first abnormality message and a second abnormality message using a second type of collision signal and a fault signal in this embodiment will be further explained below.

[0070] As an optional embodiment, the first and second abnormality prompts are output using a second type of collision signal and a fault signal, including: when the fault signal is a first type of fault signal, the first and second abnormality prompts are output using the second type of collision signal and the first type of fault signal, wherein the first type of fault signal is used to represent a fault signal sent by the first control device to the second control device via a network; or, when the fault signal is a second type of fault signal, the first and second abnormality prompts are output using the second type of collision signal and the second type of fault signal, wherein the second type of fault signal is used to represent a fault signal obtained by the second control device by converting the collision signal.

[0071] In this embodiment, the aforementioned first type of fault signal can be used to represent a fault signal sent by the first control device to the second control device via a network. For example, the aforementioned first type of fault signal can be used to represent a fault signal sent by the battery controller to the vehicle controller via a CAN network.

[0072] In this embodiment, when the fault signal is a first type of fault signal, a first abnormality warning message and a second abnormality warning message are output using the second type of collision signal and the first type of fault signal. Optionally, if the detected collision signal is determined to be a second type of collision signal, the fault signal is type-determined; if the fault signal is determined to be a first type of fault signal, the first abnormality warning message and the second abnormality warning message can be output using the second type of collision signal and the first type of fault signal. This achieves the purpose of alerting the vehicle to a collision with other objects, thereby improving the vehicle's collision protection safety.

[0073] In this embodiment, the aforementioned second type of fault signal can be used to represent a fault signal obtained by converting a collision signal using a second control device. For example, the aforementioned second type of fault signal can be used to represent a fault signal obtained by converting a collision signal using a vehicle controller.

[0074] In this embodiment, when the fault signal is a second type of fault signal, a first abnormality warning message and a second abnormality warning message are output using the second type of collision signal and the second type of fault signal. Optionally, if this embodiment determines that the detected collision signal is a second type of collision signal, it performs a type determination on the fault signal; if it determines that the fault signal is a second type of fault signal, it can output the first abnormality warning message and the second abnormality warning message using the second type of collision signal and the second type of fault signal, thereby achieving the purpose of indicating that the vehicle has collided with other objects, and thus achieving the technical effect of improving the safety of vehicle collision protection.

[0075] Optionally, collision analysis of the second type of collision signal can yield the location and time of the collision between the vehicle and other objects; fault analysis of the first type of fault signal can yield the severity of the collision between the vehicle and other objects, or fault analysis of the second type of fault signal can yield the severity of the collision between the vehicle and other objects; based on the location and time of the collision and the severity of the collision, a first abnormality warning message and a second abnormality warning message can be output, thereby achieving the purpose of alerting the vehicle to a collision with other objects, and thus realizing the technical effect of improving the safety of vehicle collision protection.

[0077] As an optional embodiment, the method further includes: obtaining the current acceleration of the vehicle at the current moment; and determining the scene in which the vehicle is located at the current moment as the target scene in response to the current acceleration being greater than or equal to a preset acceleration, wherein the preset acceleration is used to represent an acceleration threshold for determining whether the scene is the target scene.

[0078] In this embodiment, the preset acceleration can be used to represent the acceleration threshold for determining whether a scene is the target scene.

[0079] In this embodiment, the current acceleration of the vehicle at the current moment is obtained; in response to the current acceleration being greater than or equal to a preset acceleration, the scene in which the vehicle is located at the current moment is determined as the target scene.

This achieves the goal of determining the scene in which the vehicle is located at the current moment, and realizes the technical effect of improving the recognition accuracy of collision scenes.

[0080] In this embodiment of the invention, when performing collision protection on a vehicle, a collision signal can be detected based on the current scenario in which the vehicle is located. Upon detecting the collision signal, the vehicle's high-voltage circuit is disconnected via the vehicle's protection device, and a fault signal is sent from the vehicle's first control device to its second control device. If the current state of the high-voltage circuit is disconnected, an abnormality alert is output using the collision signal and the fault signal. Because in this embodiment, upon detecting a collision signal, the high-voltage circuit is disconnected via the protection device, a fault signal is sent from the first control device to the second control device, and if the current state of the high-voltage circuit is disconnected, an abnormality alert can be output using the collision signal and the fault signal.

[0090] In the vehicle collision protection system 200 of this application, when performing collision protection on the vehicle, a third control device can detect a collision signal in response to the current scenario where the vehicle is located. A protection device, in response to the detection of the collision signal, cuts off the vehicle's high-voltage circuit. A first control device, in response to the detection of the collision signal, sends a fault signal to a second control device. The second control device, in response to the current state of the high-voltage circuit being cut off, outputs an abnormality warning message using the collision signal and the fault signal. Because in this embodiment, upon detecting a collision signal, the protection device cuts off the high-voltage circuit, the first control device sends a fault signal to the second control device, and the high-voltage circuit is currently cut off, and an abnormality warning message is output using the collision signal and the fault signal, the system achieves the goal of timely protection for vehicles involved in collisions.

If the detected collision signal is determined to be a first type of collision signal, the high-voltage circuit is cut off, thereby achieving the purpose of cutting off the high-voltage circuit and thus realizing the technical effect of improving the efficiency of high-voltage power outage.

This achieves the goal of determining the scene in which the vehicle is located at the current moment and realizes the technical effect of improving the recognition accuracy of collision scenes.

[0102] The technical solutions of the embodiments of the present invention will be illustrated below with reference to preferred embodiments.

[0103] Currently, if a vehicle collides with other objects while in motion, it can cause battery leakage, and the vehicle's protection system may not be able to respond in time, resulting in low safety due to collision protection.

[0104] However, this invention proposes a vehicle collision protection method. When a collision signal is detected, a protection device cuts off the high-voltage circuit, and a first control device sends a fault signal to a second control device. When the current state of the high-voltage circuit is cut off, an abnormality warning message can be output using the collision signal and the fault signal. This achieves the purpose of timely protection for vehicles involved in collisions, thereby solving the technical problem of low safety in vehicle collision protection and achieving the technical effect of improving the safety of vehicle collision protection.

[0105] In this embodiment, by executing the high-voltage cutoff system disconnection method when a vehicle is in distress, the high-voltage circuit can be disconnected, and a fault signal can be sent from the first control device to the second control device. Furthermore, if the current state of the high-voltage circuit is disconnected, an abnormality warning message can be output using the aforementioned collision signal and fault signal. For example, Figure 3(a) is a flowchart of a high-voltage cutoff system disconnection method according to an embodiment of the present invention. As shown in Figure 3(a), the method may include the following steps:

[0106] In step S301, the SRS airbag controller identifies the collision scenario and sends a collision signal.

[0107] After the SRS airbag controller identifies the collision scenario and sends a collision signal, the process proceeds to step S302, where the battery controller receives the collision hardwire signal from the airbag controller, executes the smart safety cut-off action, and disconnects the high-voltage circuit.

[0108] After executing the intelligent insurance cut-off action and disconnecting the high-voltage circuit, the system proceeds to step S303, where the vehicle controller latches the fault and executes audio-visual signal interaction between the vehicle and the outside world.

[0109] In the technical solution provided by step S303 of the present invention, the vehicle controller records and latches faults based on the collision hardwire signal from the airbag controller and the fault signal from the battery controller, and performs audio-visual signal interaction between the vehicle and the interior and exterior.

[0110] If the vehicle controller latches a fault, after executing the interaction of the vehicle's internal and external audio and visual signals, the process proceeds to step S304, where the vehicle's internal and external lights are used to indicate that the vehicle has collided with other objects.

[0111] In the technical solution provided by step S304 of the present invention, emergency sound and light warning information is displayed on the vehicle's in-vehicle screen, and the external warning lights and microphone are turned on, thereby providing sound and light prompts outside the vehicle.

The battery controller 3111 may be deployed in the power battery 311.

[0113] In this embodiment, the battery controller 3111 can be electrically connected to the airbag controller 312 via a hard wire (shown as a solid black arrow in the figure), and the battery controller 3111 can also be electrically connected to the smart insurance 314 via a hard wire.

[0115] In this embodiment, the high-voltage accessory 315 can be electrically connected to the smart fuse 314 via a hard wire.

[0116] In this embodiment, when the airbag controller 312 detects a collision signal, it sends the collision signal to the battery controller 3111 and the vehicle controller 313. The battery controller 3111 can, based on the received collision signal, perform a cut-off operation on the smart fuse 314, thereby disconnecting the high-voltage circuit. The vehicle controller 313 can, based on the received collision signal and the fault signal from the battery controller 3111, record and latch the fault; the vehicle controller 313 can also send the received collision signal and fault signal to the large-screen control system 316. The large-screen control system 316 can, based on the received collision signal and fault signal, perform audio-visual signal interaction within the vehicle.

[0117] Figure 3(c) is a schematic diagram of data interaction between a vehicle and a server according to an embodiment of the present invention. As shown in Figure 3(c), the vehicle 320 can upload the output abnormal prompt information to the server 321. The server 321 can update the type of the abnormal prompt information and send the updated type to the vehicle 320 so that the abnormal prompt information under the updated type can be output using the collision signal and the fault signal.

[0118] In this embodiment, upon detecting a collision signal, the high-voltage circuit is disconnected by the protection device, and a fault signal is sent from the first control device to the second control device. Furthermore, if the high-voltage circuit is currently disconnected, an abnormality warning message can be output using the collision signal and the fault signal. This achieves the goal of timely protection for vehicles involved in collisions, thus solving the technical problem of low safety in vehicle collision protection and ultimately improving the safety of vehicle collision protection.
