Description

Technical Field

[0001] The present application relates to the field of vehicle intelligent technology, and in particular to a method and device for detecting external attachments, equipment, and a vehicle. Background Art

[0002] In recent years, with the rapid development of electronic technology, various electronic products with recording functions have emerged one after another. As people's awareness of security and privacy gradually increases, in the closed private environment of the car, people in the car expect a safe and private environment to exist to ensure that private conversations are not recorded by third parties. However, external attachments connected to the car hinder the construction of a safe and private environment.

[0003] There are three main types of external attachments connected to the vehicle: mechanically powered external attachments, external self-powered external attachments, and external attachments that use power from inside the vehicle. Figure 1 A specific example diagram of an external attachment that uses power from inside the vehicle, such as Figure 1 As shown, the external attachment that uses power supplied from within the vehicle can be connected to functional devices such as seat control, intelligent cockpit domain controller (CDC) or air supply, or can be connected to driving-related devices such as rear-drive motor, oil pump, suspension frame or headlights, or can be connected to the vehicle's external power supply port.

[0004] How to detect external attachments that use power from within the vehicle is a technical problem that needs to be solved urgently. Summary of the invention

[0005] The embodiments of the present application provide a method and device, equipment, and vehicle for detecting external attachments, which solve the current problem that it is impossible to effectively detect external attachments in a vehicle that use power from within the vehicle.

[0006] To achieve the above objectives, the embodiments of the present application adopt the following technical solutions:

[0007] In a first aspect, a method for detecting an external attachment is provided, the method comprising: obtaining state information of a target vehicle, and then obtaining current information of at least one port of the target vehicle when the target vehicle is in a first state. The first state includes a parking gear state and a dormant state. If the current information satisfies a preset condition, it indicates that the port is connected to an external attachment.

[0008] The external attachment detection method provided by the present application obtains the state information of the target vehicle, and then obtains the current information of at least one port of the target vehicle when the target vehicle is in the parking gear state or the dormant state. In this state, the current of the target vehicle is relatively stable, which can avoid the situation where the port current is unstable due to the floating vehicle voltage, and ensure that the result of the port connecting to the external attachment under the preset conditions indicated by the current information is more accurate, and can effectively detect the existence of external attachments in the vehicle that use the power supply in the vehicle.

[0009] In a possible implementation, when the target vehicle is in the first state, before obtaining the current information of at least one port of the target vehicle, the method further includes: receiving a first detection instruction sent by a controller of the target vehicle, wherein the first detection instruction includes port information of a first port of the target vehicle.

[0010] When the target vehicle is in a first state, current information of at least one port of the target vehicle is obtained, including: in response to a first detection instruction, when the target vehicle is in the first state, according to the port information of the first port, obtaining current information of the first port of the target vehicle.

[0011] In this possible implementation, the user can specify the port that needs to be tested, and then send a first detection instruction through the controller of the target vehicle, thereby ensuring the autonomy of the user's selection.

[0012] In a possible implementation, the parking gear state includes a parking gear standby state. In response to a first detection instruction, when the target vehicle is in the first state, current information of the first port of the target vehicle is obtained according to the port information of the first port, including: in response to the first detection instruction, when the target vehicle is in the parking gear standby state, current information of the first port of the target vehicle is obtained according to the port information of the first port.

[0013] In this possible implementation, a first detection instruction is generated according to the port to be detected specified by the user, and then the current information of the first port is obtained when the vehicle is in the parking gear standby state, which can achieve directional detection of the first port while ensuring more accurate detection results.

Receive a second detection instruction sent by the controller of the target vehicle. Wherein. The second detection instruction includes the port information of the second port of the target vehicle, the status information of the second port indicates that the current value is abnormal, and the second port is selected by the user based on the status information of each port displayed on the target vehicle. Then, in response to the second detection instruction, when the target vehicle is in the parking gear standby state, the current information of the second port of the target vehicle is obtained based on the port information of the second port.

[0015] In this possible implementation, the present application performs an overall detection on each port of the target vehicle, obtains the current information of each port, determines the status information of each port, and then sends the status information of each port to the controller of the target vehicle, which can preliminarily remind the user that there are ports with abnormal current among the ports of the target vehicle. Furthermore, the user can generate a second detection instruction based on the status information of each port, and then obtain the current information of the target vehicle in the parking gear standby state based on the port information of the second port in the second detection instruction. The ports of the target vehicle can be detected by a combination of overall detection and directional detection to make the detection results more accurate. At the same time, the ports with external attachments can be located by directional detection of the ports.

[0016] In a possible implementation, the current information includes: a current value. The preset condition includes: a difference from a target standard current value in the prefabricated current information of the target vehicle is greater than a preset threshold value. The prefabricated current information includes standard current values ​​corresponding to multiple different temperatures and different electric quantities when the target vehicle is in the first state. The temperature corresponding to the target standard current value is the current temperature of the target vehicle, and the electric quantity corresponding to the target standard current value is the current electric quantity of the target vehicle.

[0017] In this possible implementation, the current value of the port is compared with the current value of the prefabricated current information of the port in the first state of the target vehicle, and then whether the port is connected to an external attachment is determined based on the comparison result, which can make the detection result more accurate.

[0057] The technical solutions in the embodiments of the present application will be described below in conjunction with the accompanying drawings in the embodiments of the present application. In order to facilitate the clear description of the technical solutions in the embodiments of the present application, in the embodiments of the present application, the words "first", "second" and the like are used to distinguish the same items or similar items with substantially the same functions and effects. It can be understood by those skilled in the art that the words "first", "second" and the like do not limit the quantity and execution order, and the words "first", "second" and the like do not limit necessarily different. At the same time, in the embodiments of the present application, the words "exemplary" or "for example" are used to indicate examples, illustrations or explanations. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or design solutions. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a concrete manner for ease of understanding.

[0058] In addition, the transportation tools and business scenarios described in the embodiments of the present application are intended to more clearly illustrate the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided in the embodiments of the present application. Ordinary technicians in this field can know that with the evolution of transportation tools and the emergence of new business scenarios, the technical solutions provided in the embodiments of the present application are also applicable to similar technical problems.

[0059] To facilitate understanding, the relevant technical terms involved in this application are first explained.

[0060] Parking gear state: The vehicle is in the parking gear, and a mechanical device is used to lock the rotating parts of the vehicle so that the vehicle cannot move.

[0061] Sleep state: refers to the whole controller in the car entering a low power state when the car is not in use, to avoid static high power consumption and cause the whole car to be powered off. When the vehicle is in sleep state, the controller in the car only maintains a simple monitoring function waiting to be awakened, and some power-intensive functions are turned off. For example, the keyless entry system (passive entry passivestart, PEPS) of the vehicle will work when it is in sleep state, and it scans the key at a certain frequency and waits to be awakened.

[0062] Parking gear non-standby state: refers to the state where the vehicle has been started but is temporarily not moving. At this time, the vehicle's engine is running, the vehicle's systems and equipment are also running, but the vehicle will not move. In the parking gear non-standby state, the vehicle can use certain functions of the vehicle, such as playing music, using air conditioning, etc. The parking gear non-standby state usually occurs when the vehicle needs to remain in operation but does not need to move, such as in traffic congestion, waiting for traffic lights, and picking up passengers.

[0063] Parking gear standby state: The way to wake up the car by unlocking or keyless entry and polling, such as long-distance 4G unlocking or Bluetooth unlocking. In this state, the vehicle engine does not start, but the vehicle's systems and devices can run.

[0064] People's awareness of security and privacy is gradually increasing. In the closed private environment of the car, people in the car expect a safe and private environment to ensure that private conversations are not recorded or photographed by third parties. However, the external attachments of the vehicle are often used by third parties to record or photograph private information as a secret means of recording or photographing. The existence of external attachments of the vehicle poses a great security risk to people's lives and privacy.

[0065] The external attachments of the above-mentioned vehicles are mainly divided into three categories: mechanically powered external attachments, externally powered external attachments, and external attachments that use power from inside the vehicle. At present, the detection methods for external attachments that use power from inside the vehicle are mainly divided into: a method for detecting an external recorder and a method for detecting an external camera.

[0066] Among them, the method of detecting an external recorder is mainly to receive the radio signal of the vehicle, decode the radio signal to obtain the decoding information, and judge whether the vehicle has an external recorder based on the decoding information. The method of detecting an external camera is mainly to obtain the data flow in the detection vehicle space, identify the detected data flow, and after identifying the camera flow containing the light source, determine that the vehicle carries an external camera. However, these two methods only determine whether the vehicle is connected to an external recorder or an external camera through one signal detection or data flow detection, and cannot effectively guarantee the accuracy of the vehicle external device detection. At the same time, this method can only determine whether the vehicle is connected to an external recorder or an external camera, and it is difficult to accurately locate the access position of the external recorder and the external camera.

[0067] Based on this, the present application provides an external attachment detection method, an external attachment detection device, an external attachment detection equipment, a vehicle including the external attachment detection device or the external attachment detection equipment, and a storage medium, the basic principle of which is: obtaining the state information of the target vehicle, and when the target vehicle is in a first state, obtaining the current information of at least one port of the target vehicle, wherein the first state is that the target vehicle is in a parking gear state or a dormant state, which can ensure that the current of the vehicle is collected when the current of the vehicle is relatively stable. The current information indicates that the port corresponding to the current is connected to an external attachment under the preset conditions, which can effectively detect the external attachment in the vehicle that uses the power supply in the vehicle, thereby protecting the privacy information of the vehicle personnel.

[0068] It should be noted that the means of transport including the external attachment detection device or the external attachment detection equipment may be vehicles, trains, ships, airplanes, and other means of transport, and the present application does not limit the type of means of transport. The following takes the vehicle as an example to describe the external attachment detection method and device provided by the present application.

[0069] On the one hand, the external attachment detection method and device provided by the present application can be applied to Figure 2 In the illustrated vehicle 200, the vehicle 200 includes: at least one component 201, at least one port 202, and an external attachment detection device 203. The external attachment detection device 203 is deployed in the vehicle 200, one end of the external attachment detection device 203 is connected to the at least one port 202, and the other end of the external attachment detection device 203 is connected to the vehicle 200.

[0070] Exemplarily, the component 201 may be a battery, a motor, a speaker, an air conditioner, or other components of the vehicle 200. The present application does not limit the type and quantity of the component 201.

[0071] The port 202 may be a connection port for the component 201 to other devices. For example, it may be a connection port A for connecting to the vehicle's built-in camera A1 or the vehicle's built-in camera A2, or a connection port B for connecting to the vehicle's built-in recorder B, or a connection port C for connecting to other components C of the vehicle. The present application does not limit the type and number of the port 202.

[0072] The external attachment detection device 203 is used to execute the external attachment detection method provided by the present application, by obtaining the state of the vehicle 200, and then obtaining the current information of at least one port 202 of the vehicle 200 when the vehicle 200 is in the first state. At least one port is a port outside the whitelist in the port 202. The first state is that the vehicle is in the parking gear state or the dormant state, and the current of the vehicle in the first state is stable. The current information is used to indicate that at least one port 202 of the target vehicle 200 is connected to an external attachment under the preset conditions.

[0073] Figure 3 FIG. 2 is a specific example of a vehicle 200 provided in the present application. Figure 3 As shown, the vehicle 200 provided by the present application may also include: a controller 204, an input device 205, and an output device 206. Among them, the first end of the controller 204 is connected to the other end of the external attachment detection device 203. The second end of the controller 204 is connected to the input device 205. The third end of the controller 204 is connected to the output device 206.

[0074] The input device 205 is used to receive a detection instruction from a user, and the detection instruction includes port information of a port of the target vehicle. The port is selected by the user according to the status information of each port displayed by the output device 206. Exemplarily, the input device 205 can be a keyboard, a mouse, a camera, a scanner, a light pen, a handwriting input board, a joystick, a voice input device, etc., and the present application does not limit the type of the input device 205.

[0075] The output device 206 is used to provide an interactive interface for the user, and after receiving the port information sent by the controller 204, the port information is displayed to the user. Exemplarily, the output device 206 can be a display, a printer, a plotter, an image output system, a voice output system, a magnetic recording device, etc. This application does not limit the type of the output device 206.

[0076] In a possible implementation, the external attachment detection device 203 is further used to send the port information of the port 202 connected to the external attachment to the controller 204. After receiving the port information of the port of the target vehicle, the controller 204 is used to send the port information to the output device 206. The controller 204 is also used to receive the detection instruction sent by the input device 205.

[0077] In another possible implementation, the external attachment detection device 203 is further used to send the current information of the port of the target vehicle to the controller 204. The controller 204 is used to determine that at least one port of the target vehicle 200 is connected to the external attachment under a preset condition according to the current information of the port of the target vehicle. The controller 204 is also used to send the port information of the port connected to the external attachment to the output device 206. The controller 204 is also used to receive the detection instruction sent by the input device 205.

[0078] Among them, the controller 204 can be a smart cockpit domain controller (CDC) or a central control screen of the vehicle. This application does not limit the type of the controller 204.

[0079] It should be noted that the above Figure 2 or Figure 3 The illustrated vehicle 200 further illustrates an example of the application scenario of the present application solution and limits the application scenario of the present application solution.

[0080] On the other hand, the structure of the external attachment detection device provided in the embodiment of the present application can be as follows: Figure 4 The external attachment detection device 203 shown in the figure includes: a port current acquisition module 401 and a detection module 402. When the external attachment detection device 203 is applied to a vehicle, one end of the port current acquisition module 401 is connected to at least one port of the vehicle. The other end of the port current acquisition module 401 is connected to the detection module 402. The detection module 402 is connected to the controller 204 of the vehicle.

[0081] The port current acquisition module 401 is used to obtain current information of at least one port of the vehicle 200 when the vehicle 200 is in the first state, and send the current information to the detection module 402. Exemplarily, the port current acquisition module 401 can be an intelligent distribution box, and the accuracy of the port current acquisition module 401 is 10mA.

[0082] The detection module 402 is used to, after receiving the current information sent by the port current acquisition module 401, determine based on the current information that an external attachment is connected to the port under a preset condition, and send the port information of the port connected to the external attachment to the controller 204 of the vehicle 200, so that the vehicle 200 displays the port information to the user. Alternatively, the detection module 402 is used to, after receiving the current information sent by the port current acquisition module 401, send the current information to the controller 204 of the vehicle 200, and the controller 204 of the vehicle 200 determines that an external attachment is connected to the port under a preset condition.

[0083] In one possible implementation, Figure 5 As shown, the detection module 402 may include: an overall detection module 4021 and a directional detection module 4022 .

[0084] One end of the overall detection module 4021 is connected to the port current collection module 401, and the other end of the overall detection module 4021 is connected to the vehicle controller 204. One end of the directional detection module 4022 is connected to the port current collection module 401, and the other end of the directional detection module 4022 is connected to the port vehicle controller 204.

[0085] The overall detection module 4021 is used to obtain current information of at least one port of the vehicle 200 when the vehicle 200 is in the first state, determine the status information of each port according to the current information of each port, and send the status information to the vehicle 200 so that the status information of the vehicle 200 is displayed to the user.

[0086] The directional detection module 4022 is used to receive a detection instruction sent by the vehicle 200, and the detection instruction includes port information of one or more specific ports of the vehicle 200. Exemplarily, the specific port can be a port whose current is abnormal as indicated by the status information detected by the overall detection module 4021, or it can be a port specified by the user. The directional detection module 4022 is also used to respond to the detection instruction, and according to the port information of the specific port, when the vehicle 200 is in the parking gear standby state, obtain the current information of the specific port of the vehicle 200, and then determine that the port is connected to an external attachment when the current information of the specific port meets the preset conditions. In addition, the directional detection module 3022 can also send the port information of the port connected to the external attachment to the controller 204 of the vehicle 200, so that the controller 204 of the vehicle 200 displays the port information to the user.

[0087] It should be noted that the above Figure 4 or Figure 5 The illustrated external attachment detection device 203 is only an example of the application scenario of the solution of the present application, and does not limit the application scenario of the solution of the present application.

[0088] The present application embodiment provides a method for detecting external attachments. Figure 4 or Figure 5 The external attachment detection device 203 is as follows Figure 2 or Figure 3 The vehicle 200 shown performs the following steps. Figure 6 As shown, the method may include the following steps:

[0089] S601, obtaining status information of a target vehicle.

[0090] In one possible implementation, the process of obtaining the status information of the target vehicle may be that the external attachment detection device sends a vehicle status information acquisition signal to the target vehicle at a preset time, and after receiving the vehicle status information acquisition signal, the target vehicle sends the status information of the target vehicle to the external attachment detection device.

[0091] In another possible implementation, the process of obtaining the state information of the target vehicle may be to directly send the state information of the target vehicle to the external attachment detection device when the state of the target vehicle changes.

[0092] In another possible implementation, the status information of the target vehicle may include a first state and a second state, the first state including: parking gear non-standby state, parking gear standby state, dormant state, and the second state including: states of the target vehicle other than the first state, such as driving gear state or reverse gear state.

[0093] S602, when the target vehicle is in a first state, obtaining current information of at least one port of the target vehicle in the first state, wherein the current information indicates that the port is connected to an external attachment when a preset condition is met.

[0094] In a possible implementation, when the target vehicle is in a first state, the port current acquisition module of the external attachment detection device acquires current information of all ports outside the port whitelist in the first state of the target vehicle.

[0095] Exemplarily, the ports of the target vehicle include port A, port B, port C, port X, port Y and port Z. Among them, port X, port Y and port Z are ports in the port whitelist. When the target vehicle is in a parking gear state or a dormant state, the overall detection module of the external attachment detection device instructs the port current acquisition module to obtain the current information of port A, port B and port C of the target vehicle outside the whitelist.

[0096] The port whitelist refers to the port trust list of the target vehicle, that is, the ports that do not need to be detected for external attachments. Exemplarily, the port whitelist can be as shown in Table 1, wherein the port whitelist includes port X, port Y, and port Z, that is, it is not necessary to obtain the current information of port X, port Y, and port Z. The user can modify the port whitelist through the input device and output device of the target vehicle, such as adding a port or deleting a port.

[0097] Table 1 Port whitelist of target vehicles

[0098]

[0099] In this possible implementation, when the vehicle is in the parking gear state or the dormant state, the overall detection module of the target vehicle obtains the current information of all ports of the target vehicle that are not in the port whitelist through the port current acquisition module. The device port voltage of the target vehicle in the parking gear state or the dormant state is stable, thereby ensuring the current stability. Using stable current information to perform overall detection of the target vehicle can ensure more accurate detection results.

[0100] Further, such as Figure 7 As shown, the method provided in the embodiment of the present application may further include: S603.

[0101] S603: When the current information of a port of the target vehicle meets a preset condition, determine whether the port is connected to an external attachment.

[0102] Among them, the current information may include the current value of the port. The preset condition includes that the difference between the current value in the current information of a port of the target vehicle and the target standard current value in the prefabricated current information of the target vehicle is greater than the preset threshold value. The prefabricated current information includes standard current values ​​corresponding to multiple different temperatures and different electrical quantities when the target vehicle is in the first state. The temperature corresponding to the target standard current value is the current temperature of the target vehicle, and the electrical quantity corresponding to the target standard current value is the current electrical quantity of the target vehicle. The target standard current value is the standard current value of the target vehicle at the current temperature and current electrical quantity.

[0103] It should be noted that the temperature of the target vehicle can be characterized by the temperature of the cooling water of the target vehicle, and the present application does not limit the type of temperature. The power of the target vehicle can be characterized by the power of the battery of the target vehicle, and the present application does not limit the type of power.

[0104] Specifically, taking port A of the target vehicle as an example, after obtaining the current value of port A, the overall detection module of the external attachment detection device determines the standard current value of port A in the prefabricated current information of the target vehicle according to the current temperature and power of the target vehicle, and compares the current value of port A with the standard current value of port A. If the difference between the two is greater than the threshold value, it is considered that the current information of port A meets the preset condition. At this time, it can be determined that the current of port A is in an abnormal state, or that port A is connected to an external attachment. The prefabricated current information of the target vehicle includes: when the target vehicle is in the first state, the standard current values ​​corresponding to multiple different temperature and different power conditions.

[0105] In a possible implementation, the prefabricated current information of the target vehicle may specifically include first prefabricated current information, second prefabricated current information, and third prefabricated current information. Among them, the first prefabricated current information includes the standard current value corresponding to multiple different temperatures and different power conditions when the target vehicle is in a parking gear non-standby state. The second prefabricated current information includes the standard current value corresponding to multiple different temperatures and different power conditions when the target vehicle is in a parking gear standby state. The third prefabricated current information includes the standard current value corresponding to multiple different temperatures and different power conditions when the target vehicle is in a dormant state. The prefabricated current information can be prefabricated for the target vehicle to leave the scene. At the same time, the port prefabricated current information can be updated through cloud diagnosis or diagnostic instrument when the target vehicle is in a trusted diagnosis state.

[0106] Exemplarily, the first prefabricated current information, the second prefabricated current information, and the third prefabricated current information may be shown in Table 2, Table 3, and Table 4, respectively. Table 2 shows the currents at multiple temperatures when the target vehicle is in a parking gear non-standby state and multiple power levels of the target vehicle. Table 3 shows the currents at multiple temperatures when the target vehicle is in a parking gear standby state and multiple power levels of the target vehicle. Table 4 shows the currents at multiple temperatures when the target vehicle is in a dormant state and multiple power levels of the target vehicle.

[0111] Table 4 Current at multiple temperatures of the target vehicle in a dormant state and multiple power levels of the target vehicle

[0112]

[0113] Exemplarily, after the overall detection module obtains the current information of all ports outside the white list when the target vehicle is in the parking gear and non-standby state, the temperature of the target vehicle is temperature 1, the power of the target vehicle is power 1, and the standard current value under temperature 1 and power 1 in lookup table 2 is current 1, and then the current value of each port is compared with current 1. If the difference between the current value and current 1 is greater than the threshold value, it is determined that the port is connected to an external attachment.

[0114] Another possible implementation is Figure 8As shown, the method provided in the embodiment of the present application may also include S801-S803.

[0115] S801, the external attachment detection device receives a first detection instruction sent by a controller of a target vehicle.

[0116] The first detection instruction includes port information of the first port.

[0117] S802, the external attachment detection device responds to the first detection instruction, and when the target vehicle is in a parking gear standby state, the directional detection module of the external attachment detection device instructs the port current acquisition module to obtain the current information of the first port of the target vehicle according to the port information of the first port.

[0118] Exemplarily, the external attachment detection device first receives a first detection instruction sent by a controller of the target vehicle, where the first detection instruction includes port X of the target vehicle. If port X is in the whitelist of the target vehicle, port X is deleted from the whitelist, and the user places the target vehicle in a parking gear standby state. At this time, port X is in the standby state, and the port current acquisition module of the external attachment detection device obtains current information of port X.

[0119] In this possible implementation, the target vehicle generates a first detection instruction according to the port to be detected specified by the user, and sends it to the external attachment detection device. Then, when the vehicle is in the parking gear standby state, the external attachment detection device obtains the current information of the first port, which can achieve directional detection of the first port while ensuring a more accurate detection result.

[0120] S803: When the current information of the first port meets a preset condition, determine that the first port is connected to an external attachment.

[0121] Specifically, the directional detection module of the external attachment detection device compares the current value of the first port with the corresponding standard current value in the second prefabricated current information. If the difference between the current value of the first port and the corresponding standard current value in the second prefabricated current information is greater than the threshold value, it is determined that the first port is connected to the external attachment.

[0122] Exemplarily, after the directional detection module obtains the current information of port X in the parking gear standby state of the target vehicle, the temperature of the target vehicle is temperature 1 and the power of the target vehicle is power 1. The standard current value of port X at temperature 1 and power 1 in the lookup table 3 is current 1. The current value of port X is then compared with current 1. If the difference between the current value and current 1 is greater than the threshold value, it is determined that an external attachment is connected to port X.

[0123] Another possible implementation is Fig. 9As shown, the method provided in the embodiment of the present application may also include S901-S906.

[0124] S901: When a target vehicle is in a first state, the overall detection module of the external attachment detection device instructs the port current acquisition module to acquire current information of at least one port of the target vehicle.

[0125] S902, the overall detection module determines the status information of each port according to the current information of each port of the target vehicle.

[0126] S903, the external attachment detection device sends the status information of each port to the controller of the target vehicle, so that the target vehicle displays the status information to the user.

[0127] S904: The user determines a second detection instruction according to the status information of each port, and submits the second detection instruction to the external attachment detection device through the controller.

[0128] S905 , the external attachment detection device responds to the second detection instruction and instructs the port current acquisition module to obtain current information of the second port of the target vehicle according to the port information of the second port when the target vehicle is in a parking gear standby state.

[0129] S906: When the current information of the second port meets a preset condition, the directional detection module determines that the second port is connected to an external attachment.

[0130] Among them, the process of the overall detection module determining the status information of each port according to the current information of each port of the target vehicle can be that the overall detection module compares the current information of each port with the current value of the prefabricated current information of the port; if the difference between the current value of the port and the current value of the prefabricated current information is greater than a threshold value, it is determined that the current value of the port is in an abnormal state; if the difference between the current value of the port and the current value of the prefabricated current information is less than or equal to the threshold value, it is determined that the current value of the port is in a normal state.

[0131] It should be noted that in the process of comparing the current information of each port with the current value of the pre-fabricated current information of the port, if the difference between the current value of the port and the current value of the pre-fabricated current information is greater than the threshold value, it can be determined that the current state of the port is abnormal, or it can be determined that the port is connected to an external attachment. This application is not limited to this.

[0132] In this possible implementation, the present application performs an overall detection on each port of the target vehicle, obtains the current information of each port, determines the status information of each port, and then sends the status information of each port to the controller of the target vehicle, which can preliminarily remind the user that there are ports with abnormal current among the ports of the target vehicle. Furthermore, the user can generate a second detection instruction based on the status information of each port, and then obtain the current information of the target vehicle in the parking gear standby state based on the port information of the second port in the second detection instruction. The ports of the target vehicle can be detected by a combination of overall detection and directional detection to make the detection results more accurate. At the same time, the ports with external attachments can be located by directional detection of the ports.

[0133] Exemplarily, after the overall detection module obtains the current information of all ports in the parking gear non-standby state of the target vehicle, the temperature of the target vehicle is temperature 1, and the power of the target vehicle is power 1. Look up the standard current value at temperature 1 and power 1 in Table 2. Then compare the current value of each port with the standard current value, and determine that the difference between the current value of port A and the standard current value of port A is greater than the threshold value. At this time, the current value of port A is abnormal. The difference between the current value of other ports and the current value of the ports in Table 2 is less than or equal to the threshold value, which is a normal state.

[0134] Then, the status information of each port is sent to the controller of the target vehicle, and the controller displays the status information to the user when the target vehicle stops. The user generates a detection instruction of port A by selecting the directional detection port A, and submits the detection instruction to the external attachment detection device. The external attachment detection device responds to the detection instruction, and when the vehicle is in the parking gear standby state, instructs the port current acquisition module to obtain the current value of port A, and then compares the current value with the standard current value of Table 3 under the temperature and power of the vehicle at this time, and determines that the difference between the current value of port A and the standard current value of port A is greater than the threshold value, and determines that port A is connected to an external attachment at this time.

[0135] Further, such as Fig.10 As shown, the method provided in the embodiment of the present application may further include: S604.

[0136] S604, sending the current information to a controller of the target vehicle, so that the controller determines that the port is connected to the external attachment when the current information meets a preset condition.

[0137] Specifically, after obtaining the current information of at least one port of the target vehicle in the first state, the external attachment detection device can directly send the current information to the controller of the target vehicle. After receiving the current information, the controller compares the current value of the port with the current value of the pre-set current information of the port. If the difference between the current value of the port and the current value of the pre-set current information of the port is greater than the threshold value, it is determined that the port is connected to an external attachment.

[0138] The present application obtains the current information of at least one port of the target vehicle by obtaining the state information of the target vehicle, and then obtains the current information of at least one port of the target vehicle when the target vehicle is in the parking gear state or the dormant state. In this state, the current of the target vehicle is relatively stable, which can ensure that the result of the port access to the external attachment under the preset conditions indicated by the current information is more accurate, and can effectively detect the existence of external attachments in the vehicle that use the power supply in the vehicle.

[0139] The following will use specific examples to Figure 6-Figure 10 The schematic scheme is described in detail.

[0140] Example 1

[0141] like Fig.11 As shown, the external attachment detection device first obtains the state information of the target vehicle, and when the target vehicle is in the parking gear state or the dormant state, the port current acquisition module is instructed to obtain the current information of ports A, B, C and D outside the port whitelist. Then, the current values ​​of ports A, B, C and D are compared with the current values ​​of the prefabricated current information in the parking gear state or the dormant state through the overall detection module, and it is determined that the difference between the current value of port A and the current value of the prefabricated current information of port A is greater than the threshold value, and the current of port A is abnormal at this time. The difference between the current value of port B and the current value of the prefabricated current information of port B is less than the threshold value, and the current of port B is normal at this time. The difference between the current value of port C and the current value of the prefabricated current information of port C is less than the threshold value, and the current of port C is normal at this time. The difference between the current value of port D and the current value of the prefabricated current information of port D is less than the threshold value, and the current of port D is normal at this time.

[0142] The external attachment detection device sends the status information of port A, port B, port C and port D to the controller of the target vehicle, so that the controller displays the status information of port A, port B, port C and port D to the user when the vehicle is in a safe state, and the user decides whether to detect port A and determines the detection time of port A. When the user puts the vehicle in the parking gear standby state, port A is in the standby state at this time, and the user manually triggers the directional detection strategy for port A, that is, the user issues a detection instruction for port A to the directional detection module of the external attachment detection device through the controller. After receiving the detection instruction for port A, the directional detection module of the external attachment detection device obtains the current information of port A through the port current acquisition module, and then compares the current information of port A with the current value of the prefabricated current information of port A in the parking gear standby state through the directional detection module, and determines that the current value of port A at this time and the current value of the prefabricated current information of port A are greater than the threshold value, and at this time, an external attachment is connected to port A. The external attachment detection device sends the information that the port A is connected to the external attachment to the controller of the target vehicle, so that the controller displays the information that the port A is connected to the external attachment to the user.

[0143] Example 2

[0144] like Fig.12 As shown, the user first issues a detection instruction for port X through the controller of the vehicle, and the controller sends the detection instruction to the port current acquisition module of the external attachment detection device. After the external attachment detection device receives the detection instruction, the directional detection module of the external attachment detection device first checks the port whitelist. At this time, port X is in the port whitelist, and port X is deleted from the port whitelist. Then, when the user puts the vehicle in the parking gear standby state, he manually triggers the directional detection strategy for port X. At this time, the components of port X are in the standby state, and the port current detection module of the external attachment detection device obtains the current information of port X. The directional detection module compares the current value of port X with the pre-set current value of port X, and determines that the difference between the current value of port X and the current value of the pre-set current information of port X is greater than the threshold value. At this time, port X is connected to an external attachment. The external attachment detection device sends the information that port X is connected to an external attachment to the controller of the target vehicle, so that the controller displays the information that port X is connected to an external attachment to the user.
