Description

Technical Field

[0001] The present application relates to the field of vehicle technology, and more specifically, to a vehicle anti-theft method, device, vehicle and computer-readable storage medium in the field of vehicle technology. Background Art

[0002] Current vehicles are equipped with anti-theft alarm systems. When items in the vehicle are stolen, the anti-theft alarm system can only send an alarm message to remind the owner that the items in the vehicle have been stolen, but cannot prevent the thief from stealing. Summary of the invention

[0003] The present application provides a vehicle anti-theft method, device, vehicle and computer-readable storage medium. The method can control the vehicle hood to always remain in a closed state if it is detected that the vehicle hood is abnormally opened when the owner is away from the vehicle, thereby preventing the vehicle from being stolen.

[0004] In a first aspect, a vehicle anti-theft method is provided, the vehicle anti-theft method comprising: obtaining a vehicle owner's position and a vehicle position; when a target distance between the vehicle owner's position and the vehicle position is greater than a preset distance, determining whether a current state of a vehicle hood is an open state; when the current state is an open state, executing a vehicle anti-theft strategy to control the vehicle hood to remain in a closed state.

[0005] In the above technical scheme, by obtaining the owner's position and the vehicle's position, when the target distance between the owner's position and the vehicle's position is greater than a preset distance, it is determined whether the current state of the vehicle hood is an open state. When the current state is an open state, a vehicle anti-theft strategy is executed to control the vehicle hood to remain in a closed state. This technical scheme can control the vehicle hood to always remain in a closed state if it is determined that the vehicle cannot be seen by the owner and the vehicle hood is abnormally opened when the owner turns off the engine, parks, and locks the vehicle, which can effectively prevent people outside the vehicle from opening the vehicle hood, thereby preventing the parts and items in the cabin from being stolen.

[0006] In combination with the first aspect, in some possible implementations, determining whether the current state of the vehicle hood is an open state includes: determining whether a locking module of the vehicle hood is unlocked to determine whether the current state of the vehicle hood is an open state.

[0007] In combination with the first aspect, in some possible implementations, determining whether the current state of the vehicle hood is an open state includes: determining whether the lifting mechanism of the vehicle hood is extended, and / or determining whether the angle between the lifting mechanism and the cabin frame is greater than a preset angle, so as to determine whether the current state of the vehicle hood is an open state.

[0008] In combination with the first aspect, in some possible implementations, determining whether the current state of the vehicle hood is an open state includes:

[0009] Obtaining the current rotation speed of the first drive motor, wherein the first drive motor is used to drive the extension and retraction of the lifting mechanism of the vehicle hood; determining whether the current rotation speed is greater than a preset rotation speed to determine whether the current state of the vehicle hood is an open state.

[0010] In the above technical solution, by determining whether the current state of the vehicle hood is an open state through the above multiple methods, it is possible to flexibly determine whether the vehicle hood is abnormally open, which is conducive to improving the accuracy of the determination.

[0011] In combination with the first aspect and the above-mentioned implementation methods, in some possible implementation methods, executing the vehicle anti-theft strategy includes: controlling the first drive motor to drive the lifting mechanism of the vehicle hood to shorten so as to restore it to a preset position; when the lifting mechanism is restored to the preset position, controlling the locking module of the vehicle hood to lock and prohibiting the output shaft of the first drive motor from rotating; sending an alarm message to the target terminal bound to the vehicle, the alarm message including vehicle theft abnormal information and / or vehicle positioning information.

[0012] In the above technical solution, by controlling the locking module of the vehicle hood to lock and prohibiting the output shaft of the first drive motor from rotating, the output shaft of the first drive motor can be prevented from rotating. If the output shaft of the first drive motor does not rotate, the lifting mechanism will not stand up or extend. The lifting mechanism will generate a pulling force on the inner edge of the vehicle hood, so that the vehicle hood is tightly closed, which effectively increases the difficulty for thieves to open the vehicle hood. People outside the vehicle cannot see into the cabin, let alone get the items in the cabin, which effectively prevents the parts and items in the cabin from being stolen. And by sending an alarm message to the target terminal bound to the vehicle, the owner can be reminded in time that his vehicle has been stolen, and the owner can be helped to indicate the location of the vehicle, so as to find the vehicle quickly and conveniently.

[0013] In combination with the first aspect and the above-mentioned implementation methods, in some possible implementation methods, a nut is provided on the edge of the inner frame of the vehicle hood, a through hole is opened on the surface of the cabin frame opposite to the edge of the inner frame, and a rotating mechanism is provided in the inner cavity of the cabin frame, and the rotating mechanism includes a second drive motor and a connecting rod, the connecting rod is rotatably connected to the cabin frame, the second drive motor is fixedly connected to the cabin frame, the second drive motor is used to drive the connecting rod to rotate, the connecting rod is vertically arranged, and the top end of the connecting rod is located in the through hole, the top end of the connecting rod has a thread, and when the vehicle hood is in a closed state, the nut is located in the through hole; after the locking module that controls the vehicle hood is locked, the vehicle anti-theft method also includes: controlling the second drive motor to drive the connecting rod to rotate so that the top end of the connecting rod is threadedly connected to the nut.

[0014] In the above technical solution, after the locking module of the vehicle hood is controlled to be locked, the second driving motor is controlled to drive the connecting rod to rotate. After the connecting rod rotates, the top of the connecting rod is threadedly connected to the nut of the vehicle hood, which is equivalent to a secondary locking when the vehicle hood is locked by the locking module. In addition, the lifting mechanism will not stand up and will not extend, which is equivalent to locking the vehicle hood in three different ways. Even if the locking module is damaged, the vehicle hood cannot be opened. In addition, the connecting rod, the nut and the through hole each include at least one. After the top of the connecting rod is threadedly connected to the nut, the connecting rod will generate a pulling force on the inner left and right edges of the vehicle hood, so that the vehicle hood is tightly closed, further increasing the difficulty for thieves to open the vehicle hood.

[0015] In combination with the first aspect and the above-mentioned implementation methods, in some possible implementation methods, the vehicle anti-theft method also includes: responding to a vehicle theft instruction sent by a target terminal bound to the vehicle, cutting off the power supply of the vehicle, controlling the braking system of the vehicle to perform a braking operation, and maintaining the braking operation; sending vehicle positioning information to the target terminal.

[0016] In the above technical solution, after the car owner finds that his vehicle has been stolen by a thief, he can remotely control the vehicle, that is, send a vehicle theft command to the body domain controller remotely through the target terminal bound to the vehicle. The body domain controller responds to the vehicle theft command, thereby cutting off the power supply of the vehicle, controlling the vehicle's brake system to perform the braking operation, and maintaining the braking operation. The thief cannot continue to drive the vehicle, preventing the vehicle from getting farther away from the owner. In order to ensure that the owner can accurately find the vehicle, the body domain controller sends the vehicle positioning information to the target terminal, so that the owner can find the vehicle in time and reduce losses.

[0042] 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.

[0043] 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.

[0044] Since most vehicles have an engine compartment and a trunk, the engine compartment of fuel vehicles is equipped with an engine and other components, while new energy electric vehicles do not have an engine. The engine compartment is used as a storage compartment for storing items. When the owner is away from the vehicle, in order to steal items in the engine compartment and / or trunk of the vehicle, the thief will forcibly pry open the engine compartment cover to steal the components or items in the engine compartment, or will forcibly pry open the trunk lid to steal the components or items in the trunk, causing economic losses to the owner. Among them, the engine compartment and the trunk are collectively referred to as the engine compartment in the following embodiments, and the engine compartment cover and the trunk lid are collectively referred to as the vehicle hood in the following embodiments.

[0045] Based on the above problems, the embodiments of the present application propose a vehicle anti-theft method, device, vehicle and computer-readable storage medium. When the vehicle is not within the owner's field of vision, if it is detected that the vehicle hood is abnormally open, the vehicle hood is controlled to always remain in a closed state to prevent items stored in the vehicle from being stolen.

[0046] The following is an embodiment of a vehicle anti-theft method provided in an embodiment of the present application.

[0047] Figure 1 FIG. 1 is a schematic flow chart of a vehicle anti-theft method provided in an embodiment of the present application. Figure 1 As shown, the vehicle anti-theft method provided in the embodiment of the present application is applied to the vehicle body domain controller, and the vehicle anti-theft method includes the following schemes:

[0048] S110: Obtain the vehicle owner's location and the vehicle's location.

[0049] In an example embodiment, after detecting that the car owner has turned off the engine, parked the car, and locked the car, the car owner's location and the vehicle's location are obtained. The car owner's location can be determined by the location of a mobile terminal carried by the car owner, and the vehicle's location can be obtained by a positioning module of the vehicle.

[0050] S120: When the target distance between the vehicle owner's position and the vehicle's position is greater than a preset distance, determining whether the current state of the vehicle hood is an open state.

[0051] After obtaining the position of the owner and the vehicle, the target distance between the position of the owner and the vehicle is calculated, and the size relationship between the target distance and the preset distance is determined. If the target distance is less than or equal to the preset distance, it means that the vehicle can be seen within the field of vision of the owner. If a thief steals, the owner can see it, and the anti-theft function can be activated. If the target distance is greater than the preset distance, it means that the vehicle can no longer be seen within the field of vision of the owner. If a thief steals, the owner cannot see it, and there is a risk that the things in the vehicle will be stolen and / or the vehicle will be stolen. In this case, the anti-theft function is activated, that is, when the owner turns off the engine, parks the vehicle, locks the vehicle, and it is determined that the vehicle cannot be seen by the owner, it is determined whether the current state of the vehicle hood is open.

[0052] In a possible implementation, the above-mentioned determination of whether the current state of the vehicle hood of the vehicle is an open state includes the following schemes:

[0053] It is determined whether the locking module of the vehicle hood is unlocked to determine whether the current state of the vehicle hood is an open state.

[0054] Figure 2 A vehicle hood control system block diagram of a vehicle is shown, such as Figure 2As shown, the locking module and the first drive motor of the vehicle hood are connected to the vehicle hood controller, the first drive motor is connected to the lifting mechanism of the vehicle hood, the vehicle hood controller is connected to the body domain controller, and the vehicle hood has the function of automatic opening. The control process of automatic opening is: the body domain controller responds to the command of automatic opening of the vehicle hood, the body domain controller sends the opening command to the vehicle hood controller, the vehicle hood controller controls the locking module to unlock, the vehicle hood opens, and controls the first drive motor to rotate. When the first drive motor rotates, the lifting mechanism is driven to extend, and the vehicle hood opens to a larger angle. The vehicle hood has the function of manual opening, and the control process of manual opening is: first let the locking module unlock, the vehicle hood opens, the user lifts the vehicle hood, and the vehicle hood opens to a larger angle. Among them, the locking module of the vehicle hood is unlocked, indicating that the vehicle hood has been opened, but the vehicle hood is currently in a closed state and the cabin cannot be seen.

[0055] The first way to determine whether the current state of the vehicle hood is open: Since the locking module is controlled by the body domain controller through the vehicle hood controller, after the locking module is unlocked or locked, the locking module will send its own unlocking signal or locking signal to the body domain controller through the vehicle hood controller. The body domain controller can determine whether the locking module has been unlocked or locked based on the received signal. Therefore, when the owner turns off the engine, parks the car, locks the car, and it is determined that the vehicle cannot be seen by the owner, it is determined whether the current state of the vehicle hood is open by determining whether the locking module of the vehicle hood is unlocked. If the locking module of the vehicle hood is locked, it means that the current state of the vehicle hood is closed; if the locking module of the vehicle hood is unlocked, it means that the current state of the vehicle hood is open, and it is determined that the vehicle hood is abnormally open.

[0056] In a possible implementation, the above-mentioned determination of whether the current state of the vehicle hood of the vehicle is an open state includes the following schemes:

[0057] Determine whether the lifting mechanism of the vehicle hood is extended, and / or determine whether the angle between the lifting mechanism and the cabin frame is greater than a preset angle, so as to determine whether the current state of the vehicle hood is an open state.

[0058] The second method for determining whether the current state of the vehicle hood is the open state is: Figure 3 As shown, Figure 3An exemplary schematic diagram of a vehicle hood opening at a certain angle is shown, 201 represents the vehicle hood, 202 represents the cabin frame of the cabin, a represents the angle between the lifting mechanism and the cabin frame, 203 represents the lifting mechanism, the lifting mechanism is used to control the opening angle of the vehicle hood, for example, the lifting mechanism is a telescopic rod, the telescopic rod is gradually erected and gradually extended, and the opening angle of the vehicle hood gradually increases. When the vehicle hood is closed, that is, the inner side of the vehicle hood contacts the cabin frame, a is 0, and the lifting mechanism is completely retracted. Among them, a is 0 and will not be extended.

[0059] Therefore, when the owner turns off the engine, parks the vehicle, locks the vehicle, and has determined that the vehicle cannot be seen by the owner, it is possible to determine whether the current state of the vehicle hood is an open state by determining whether the lifting mechanism of the vehicle hood is extended, and / or by determining whether the angle between the lifting mechanism and the cabin frame is greater than a preset angle. If the lifting mechanism is extended and / or a is greater than the preset angle, it means that the current state of the vehicle hood is an open state, and it is determined that the vehicle hood is abnormally open.

[0060] In a possible implementation, the above-mentioned determination of whether the current state of the vehicle hood of the vehicle is an open state includes the following schemes:

[0061] Acquire the current rotation speed of the first drive motor; wherein the first drive motor is used to drive the lifting mechanism of the vehicle hood to extend and retract;

[0062] It is determined whether the current rotation speed is greater than a preset rotation speed to determine whether the current state of the vehicle hood is an open state.

[0063] The third way to determine whether the current state of the vehicle hood is the open state: Since the first drive motor is connected to the lifting mechanism by transmission, and is used to drive the lifting mechanism to extend and retract, the automatic opening of the vehicle hood is that the first drive motor drives the lifting mechanism to extend when it rotates, and the vehicle hood opens to a larger angle. When the vehicle hood is closed, the first drive motor is not working, that is, the output shaft of the first drive motor has no rotation speed. If there is a rotation speed, the lifting mechanism will be driven to extend, and the angle between the vehicle hood and the cabin frame will increase, that is, the opening angle of the vehicle hood will increase. When the vehicle hood is manually lifted, the angle between the lifting mechanism and the cabin frame increases, and the lifting mechanism is driven to extend. Because the first drive motor and the lifting mechanism are in a transmission connection relationship, the output shaft of the first drive motor will rotate, and the output shaft will have a rotation speed.

[0064] Therefore, when the owner turns off the engine, parks, locks the vehicle, and has determined that the vehicle cannot be seen by the owner, it can be determined whether the current state of the vehicle hood is open by determining whether the current speed of the first drive motor is greater than the preset speed. If the current speed is greater than the preset speed, it means that the current state of the vehicle hood is open, and it is determined that the vehicle hood is abnormally open. The preset speed is generally 0.

[0065] When the vehicle owner turns off the engine, parks, locks the vehicle, and has determined that the vehicle cannot be seen by the owner, the above-mentioned multiple methods can be used to determine whether the current state of the vehicle hood is open, which can flexibly determine whether the vehicle hood is abnormally open, thereby helping to improve the accuracy of the judgment.

[0066] S130: When the current state is the open state, executing a vehicle anti-theft strategy to control the vehicle hood to remain in the closed state.

[0067] The vehicle anti-theft strategy refers to a strategy to prevent the theft of items in the vehicle. After determining that the vehicle hood is abnormally opened, the vehicle anti-theft strategy is executed to control the vehicle hood to always remain closed. People outside the vehicle cannot open the vehicle hood with just their hands or simple tools, which can effectively prevent the theft of parts and items in the cabin. When the owner is detected approaching the vehicle, the anti-theft function is automatically turned off, and the owner can open the vehicle hood normally.

[0068] In a possible implementation, the above-mentioned vehicle anti-theft strategy includes the following solutions:

[0069] Controlling the first drive motor to drive the lifting mechanism of the vehicle hood to shorten so as to restore to a preset position;

[0070] When the lifting mechanism returns to the preset position, controlling the locking module of the vehicle hood to lock and prohibiting the output shaft of the first drive motor from rotating;

[0071] Sending an alarm message to a target terminal bound to the vehicle, wherein the alarm message includes vehicle theft abnormality information and / or vehicle positioning information.

[0072] After determining that the vehicle hood is abnormally opened, the first drive motor is controlled to rotate so that the lifting mechanism is shortened, thereby restoring the lifting mechanism to a preset position. After the lifting mechanism is restored to the preset position, the angle between the lifting mechanism and the cabin frame is 0, that is, Figure 3a in is 0. In order to ensure whether a is indeed 0, an additional angle sensor is also provided. If the angle detected by the angle sensor is 0, the locking module of the vehicle hood is controlled to be locked, and the output shaft of the first drive motor is prohibited from rotating. That is, while the vehicle hood is locked, the output shaft of the first drive motor is stuck and the output shaft of the first drive motor is not allowed to rotate. If the output shaft of the first drive motor does not rotate, the lifting mechanism will not stand up or extend. Even if the locking module is unlocked, the lifting mechanism cannot be opened to a larger angle, and the cabin cannot be seen, let alone the items in the cabin, which effectively prevents the parts and items in the cabin from being stolen.

[0073] When the output shaft of the first drive motor does not rotate, the lifting mechanism does not stand up, and does not extend, since the cabin frame is connected to the vehicle hood through the lifting mechanism, the lifting mechanism will generate a pulling force on the inner edge of the vehicle hood. Usually, the lifting mechanism includes two, which are symmetrically arranged on the left and right sides of the cabin frame, that is, the left and right lifting mechanisms will generate a pulling force on the inner left and right edges of the vehicle hood, thereby making the vehicle hood tightly closed, effectively increasing the difficulty for thieves to open the vehicle hood.

[0074] like Figure 2 As shown, the vehicle domain control is also connected to the vehicle networking module, which communicates with the target terminal bound to the vehicle; wherein the target terminal is the owner's mobile terminal, such as a mobile phone. After determining that the vehicle hood is abnormally opened, an alarm message is sent to the target terminal in a timely manner, and the alarm message includes vehicle theft abnormal information and / or vehicle positioning information. The vehicle theft abnormal information is used to remind the owner that his vehicle has been stolen.

[0075] In one possible implementation, in order to further keep the vehicle hood tightly closed and increase the difficulty of prying the vehicle hood open by external force, additional components are provided on the vehicle hood and the cabin frame. Figure 4 As shown, Figure 4 The internal structure diagram of the cabin frame and the top view of the cabin are shown. Figure 4 A in the figure represents the internal structure of the cabin frame. Figure 4B in the figure represents a top view of the cabin. A nut 204 is provided on the edge of the inner frame of the vehicle hood 201, a through hole 210 is provided on the surface of the cabin frame 202 opposite to the edge of the inner frame, a rotating mechanism is provided in the inner cavity of the cabin frame 202, the rotating mechanism includes a second drive motor 205 and a connecting rod 206, the connecting rod 206 is rotatably connected to the cabin frame 202, the second drive motor 205 is fixedly connected to the cabin frame 202, the second drive motor 205 is used to drive the connecting rod 206 to rotate, the connecting rod 206 is vertically arranged, and the top end of the connecting rod 206 is located in the through hole 210, the top end of the connecting rod 206 has a thread, and when the vehicle hood 201 is in a closed state, the nut 204 is located in the through hole 210.

[0076] A fixing seat 209 is fixedly provided in the cabin frame 202, and the connecting rod 206 is arranged through the fixing seat 209, and the part of the connecting rod 206 that passes through the fixing seat 209 is rotatably connected with the fixing seat 209, that is, the connecting rod 206 can rotate in the fixing seat 209, and the fixing seat 209 can keep the connecting rod 206 vertically arranged, and the position where the connecting rod 206 passes through the top and the bottom of the fixing seat 209 is fixed with a limit stopper 211, and the limit stopper 211 can prevent the connecting rod 206 from being separated from the fixing seat 209. A worm 208 is provided on the output shaft of the second drive motor 205, and a worm wheel 207 is fixedly provided at the bottom end of the connecting rod 206, and the worm 208 and the worm wheel 207 are meshed, and when the second drive motor 205 rotates, the connecting rod 206 also rotates. The connecting rod 206 is separately arranged from the second drive motor 205, which can ensure the stability of the threaded connection between the top of the connecting rod and the nut. Of course, the connecting rod 206 can also be replaced by the output shaft of the second drive motor 205. It is only necessary to ensure that the second drive motor 205 is fixed, the output shaft of the second drive motor 205 is vertically arranged, and the output shaft of the second drive motor 205 is located in the through hole 210. The top end of the output shaft of the second drive motor 205 has a thread. The worm 208, the worm wheel 207, the fixed seat 209, and the limit block 211 are not required, thereby reducing the complexity of installation.

[0077] After the locking module controlling the vehicle hood to be locked, the vehicle anti-theft method further includes:

[0078] The second driving motor is controlled to drive the connecting rod to rotate, so that the top end of the connecting rod is threadedly connected with the nut.

[0079] When it is determined that the vehicle hood is abnormally opened, after the locking module of the vehicle hood is controlled to be locked, the second drive motor is also controlled to drive the connecting rod to rotate. After the connecting rod rotates, the top of the connecting rod is threadedly connected to the nut of the vehicle hood, which is equivalent to a secondary locking when the vehicle hood is locked by the locking module. In addition, the lifting mechanism will not stand up and will not extend, which is equivalent to locking the vehicle hood in three different ways. Even if the locking module is damaged, the vehicle hood cannot be opened. In addition, the connecting rod, nut and through hole each include at least one. After the top of the connecting rod is threadedly connected to the nut, the connecting rod will generate a pulling force on the inner left and right edges of the vehicle hood, so that the vehicle hood is tightly closed, further increasing the difficulty for thieves to open the vehicle hood.

[0080] In a possible implementation, the above vehicle anti-theft method also includes the following solutions:

[0081] In response to a vehicle theft instruction sent by a target terminal bound to the vehicle, cutting off the power supply of the vehicle, controlling the brake system of the vehicle to perform a braking operation, and maintaining the braking operation;

[0082] The vehicle positioning information is sent to the target terminal.

[0083] If the owner finds that his vehicle has been stolen, he can remotely control the vehicle and execute the protection strategy after the vehicle is stolen through the target terminal. That is, the target terminal bound to the vehicle sends the vehicle theft command. After the vehicle networking module receives the vehicle theft command, it sends the vehicle theft command to the body domain controller. The body domain controller responds to the vehicle theft command, thereby cutting off the power supply of the vehicle, controlling the vehicle's brake system to perform the brake operation, and maintaining the brake operation. The thief cannot continue to drive the vehicle, preventing the vehicle from getting farther away from the owner. In order to ensure that the owner can accurately find the vehicle, the body domain controller sends the vehicle positioning information to the target terminal, so that the owner can retrieve the vehicle in time and reduce losses.
