Description

Technical Field

[0001] The present invention relates to the technical field of automotive safety, and particularly to an automotive anti-theft method, system and vehicle. Background Art

[0002] With the increasing demand for comfort, cars have become an essential means of transportation. Consequently, automotive engineers need to consider the anti-theft problems of cars.

[0003] Currently, the automotive anti-theft systems on the market usually have a moving object detection function, mainly used to detect whether there are living things such as children or pets in the vehicle. The automotive anti-theft system includes an ultrasonic sensor and a gravity sensor. Among them, the ultrasonic sensor emits ultrasonic waves and detects the reflected signals to determine whether there are moving objects in the vehicle; if a change in the reflected signal is detected, it indicates that there may be a moving object in the vehicle, thus triggering an alarm. The gravity sensor is installed on the seat and determines whether an object has moved by detecting the change in pressure on the seat; if a change in pressure is detected, an alarm will also be triggered.

[0004] There is also an automotive anti-theft system that realizes the anti-theft function through the communication and matching between an electronic control unit (ECU) and a smart key. When the vehicle owner starts the vehicle with a legitimate smart key, the smart key sends an encrypted signal to the ECU, and only when the signal matches successfully can the engine of the vehicle start. This authentication process based on radio frequency identification (RFID) technology ensures that only the legitimate key holder can start the vehicle, effectively preventing thieves from starting the vehicle with an illegal key, thereby protecting the property safety of the vehicle owner.

[0005] However, the existing automotive anti-theft systems do not consider the scenario where there is a legitimate key left in the vehicle, so they cannot avoid the risk of vehicle theft caused by a legitimate key left in the vehicle; the existing automotive anti-theft systems also do not consider how to disable the control switches in the vehicle to reduce the probability of theft of items in the vehicle.

[0006] Therefore, how to avoid the risk of vehicle theft caused by a legitimate key left in the vehicle and how to disable the control switches in the vehicle to reduce the probability of theft of items in the vehicle are technical problems that need to be solved urgently. Summary of the Invention

[0007] To solve the above technical problems, the present invention specifically provides the following technical solutions.

[0008] The present invention provides an automotive anti-theft method, including the following steps: S1, after the vehicle is locked by an external method, search for a left-behind key in the vehicle within a preset detection period and determine whether the vehicle meets a preset disabling condition; S2. If there is a left-behind key in the vehicle during the detection period and the vehicle meets a preset first disabling condition, then disable the left-behind key in the vehicle; S3. If the vehicle meets a preset second disabling condition during the detection period, then disable a preset control switch in the vehicle.

[0009] Optionally, the method further includes the following steps: S4. If the vehicle meets a preset unlocking condition, then perform an unlocking operation on the disabled left-behind key and control switch.

[0010] The step S4 includes: When the vehicle is started as a whole or externally unlocked as a whole, perform an unlocking operation on the disabled left-behind key and control switch.

[0011] Optionally, the step S2 includes: If there is a left-behind key in the vehicle during the detection period, and the vehicle does not meet any of the conditions of being unlocked as a whole, the vehicle mode is switched to a preset convenience mode or activation mode or driving mode, and a preset first in-vehicle switch is turned on, then disable the left-behind key in the vehicle.

[0012] Optionally, the step S2 further includes: If the left-behind key in the vehicle includes the key used to lock the vehicle in the step S1, then the key used to lock the vehicle in the step S1 is not disabled.

[0013] Optionally, the step S3 includes: If the vehicle meets a preset second disabling condition during the detection period, then disable the door switch, front hood switch, trunk switch, and glove box switch in the vehicle.

[0014] Optionally, the step S3 includes: If the vehicle does not meet any of the conditions of any door being opened and a preset second in-vehicle switch being operated during the detection period, then disable the door switch, front hood switch, trunk switch, and glove box switch in the vehicle.

[0015] In addition, the present invention further provides an automotive anti-theft system, including: A judgment module, configured to search for whether there is a left-behind key in the vehicle during a preset detection period after the vehicle is locked by an external method, and judge whether the vehicle meets a preset disabling condition; A left-behind key disabling module, configured to disable the left-behind key in the vehicle when there is a left-behind key in the vehicle during the detection period and the vehicle meets a preset first disabling condition; A control switch disabling module, configured to disable a preset control switch inside the vehicle when the vehicle meets a preset second disabling condition during the detection period.

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] The specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0022] Although each step in the schematic flowchart in the embodiment of the present invention is shown in sequence according to the indication of the arrow, these steps are not necessarily executed in the order indicated by the arrow. Unless there is a clear description in this article, the execution of these steps has no strict order limitation, and they can be executed in other orders. Moreover, at least a part of the steps in the figure may include multiple sub-steps or multiple stages. These sub-steps or stages are not necessarily executed at the same time, but can be executed at different times, and their execution order is not necessarily sequential, but can be executed alternately or alternately with at least a part of other steps or sub-steps or stages of other steps.

[0023] In the following description, suffixes such as "module" and "device" used to represent components are only for the convenience of explaining the present application, and they have no specific meaning in themselves. Therefore, "module" and "device" can be used interchangeably.

[0024] Although terms such as first, second, and third may be used herein to describe various information, such information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other.

[0025] Referring to Figure 1 , an embodiment of one aspect of the present application provides an anti-theft method for an automobile, including the following steps: S1. After the vehicle is locked by an external method, search for a remaining key in the vehicle within a preset detection period, and determine whether the vehicle meets a preset disabling condition.

[0026] S2. If there is a remaining key in the vehicle within the detection period and the vehicle meets a preset first disabling condition, disable the remaining key in the vehicle.

[0027] S3. If the vehicle meets a preset second disabling condition within the detection period, disable a preset control switch in the vehicle.

[0028] Among them, the preset detection period is preferably 30 seconds. After the vehicle is locked by an external method such as a mobile phone APP, a Bluetooth key, a remote control key, an NFC card, or face recognition, the data processing device can start timing for 30 seconds, and at the same time, send a request to search for a remaining key in the vehicle to the key management system of the vehicle through the data processing device, so that the key management system searches for the remaining key in the vehicle. If there is a remaining key in the vehicle, the key management system sends the ID of the remaining key to the data processing device. Within 30 seconds after the data processing device starts timing, if there is a remaining key in the vehicle and the data processing device determines that the vehicle meets a preset first disabling condition, the data processing device sends the ID of the remaining key and a key disabling request to the key management system, so that the key management system disables the remaining key in the vehicle and sends the enabling state of the remaining key to the data processing device, and the data processing device saves the enabling state of the remaining key to the non-volatile memory of the vehicle. If a request such as starting the vehicle, unlocking the whole vehicle, locking the whole vehicle, or opening the vehicle door is made using the remaining key, a determination of not responding to the request can be made through the data processing device according to the enabling state of the remaining key, thereby avoiding the vehicle from being stolen.

[0029] Within 30 seconds after the data processing device starts timing, the data processing device determines whether the vehicle meets a preset second disabling condition. If the vehicle meets the preset second disabling condition, the data processing device disables a preset control switch inside the vehicle. If the vehicle does not meet the preset second disabling condition, the preset control switch inside the vehicle is not disabled, and the timing of the data processing device is cleared and the timing function of the data processing device is turned off.

[0030] Among them, the key management system refers to the system in the vehicle for managing vehicle keys. The data processing device can be, for example, an in-vehicle computer or other data processing terminals capable of communicating with the vehicle, such as a smart phone. In this embodiment, the data processing device is preferably the body controller of the vehicle. The body control module (BCM), also known as the body computer, refers to the electronic control unit used to control the body electrical system in automotive engineering. By connecting with other in-vehicle ECUs, it coordinates various functions of the vehicle to ensure their normal operation. The body controller receives information input by sensors or other devices, converts this information into signals that can be received by the microprocessor, and stores, calculates, analyzes, and processes them. The body controller calculates the execution command data based on the input information parameters, outputs the execution command, and controls the corresponding vehicle electrical equipment.

[0031] The method may further include the following steps: S4, if the vehicle meets the preset unlocking condition, perform an unlocking operation on the disabled remaining key and control switch.

[0032] Among them, the unlocking operation may include: the data processing device determines whether the vehicle meets the preset unlocking condition. If the vehicle meets the preset unlocking condition, the data processing device sends the ID of the remaining key and a key unlocking request to the key management system, so that the key management system unlocks the remaining key inside the vehicle and sends the enabling state of the remaining key to the data processing device; at the same time, the data processing device unlocks the preset control switch inside the vehicle.

[0033] The step S4 may include: After the vehicle starts as a whole or is externally unlocked as a whole, perform an unlocking operation on the disabled remaining key and control switch.

[0034] The step S2 may include: If there is a remaining key inside the vehicle during the detection period, and the vehicle does not meet any of the conditions of vehicle unlocking, the vehicle mode is switched to a preset convenience mode or activation mode or driving mode, and a preset first in-vehicle switch is turned on, then the remaining key inside the vehicle is disabled.

[0035] In this embodiment, the convenience mode is preferably when the vehicle is not started, the in-vehicle large screen is clickable, and the air conditioner and windows of the vehicle can be controlled; the activation mode is preferably when the vehicle power system exits operation; the driving mode is preferably when the vehicle is in the started state.

[0036] In this embodiment, the preset first in-vehicle switch is preferably any one of the door switch, tailgate switch, central control unlocking switch, central control locking switch, tailgate switch, and glove box switch.

[0037] Step S2 may further include: If the key used to lock the vehicle in step S1 is included in the remaining keys in the vehicle, the key used to lock the vehicle in step S1 is not disabled.

[0038] The principle of this operation is that the key used to lock the vehicle in step S1 is not disabled, which facilitates the vehicle owner to unlock the vehicle with the key used to lock the vehicle in step S1.

[0039] Among them, the key used to lock the vehicle in step S1 can be a Bluetooth key or a remote control key.

[0040] Step S3 may include: If the vehicle meets the preset second disabling condition during the detection period, disable the door switch, front hood switch, tailgate switch, and glove box switch in the vehicle.

[0041] Step S3 may include: If the vehicle does not meet any of the conditions that any door is opened and any of the preset second in-vehicle switches is operated during the detection period, disable the door switch, front hood switch, tailgate switch, and glove box switch in the vehicle.

[0042] Among them, the door can be an electrically released door or an electric door, and the vehicle doors can include the driver's door, co-driver's door, second-row door, and third-row door.

[0043] In this embodiment, the preset second in-vehicle switch is preferably any one of the door switch, tailgate switch, human-machine interface (HMI) large screen unlocking switch, HMI voice unlocking switch, glove box switch, and front hood switch. In other embodiments, the preset second in-vehicle switch can also be any switch related to vehicle safety or privacy.

[0044] Through the above technical solution, it is possible to achieve the function of automatically disabling the remaining keys in the vehicle and the preset control switches in the vehicle after the vehicle is locked by an external method, solving the problem of vehicle theft caused by the existence of remaining legal keys in the vehicle and the problem of theft of items in the vehicle caused by the failure to disable the control switches in the vehicle, thereby achieving the purpose of protecting the property safety of the vehicle owner.

[0045] In addition, the vehicle owner can also bind the vehicle key on the preset remote key management APP. If the vehicle owner accidentally loses the key, the lost key can be disabled on the remote key management APP, thus avoiding vehicle theft.

[0046] Among them, the specific operations for binding the vehicle key on the remote key management APP may include: receiving the VIN code of the vehicle input by the vehicle owner through the remote key management APP, and retrieving and displaying all the physical key information of the vehicle from the background according to the VIN code of the vehicle. The physical keys may include Bluetooth keys, remote control keys, NFC cards, etc. The operation of customizing the name of the displayed physical key can be received through the remote key management APP, and then the operation of binding a single physical key or all physical keys can be received. If the information of the bound physical key changes, for example, the ID of the physical key changes, the changed physical key can be rebound through the remote key management APP.

[0047] The specific operations for disabling the vehicle key on the remote key management APP may include: receiving the operation of disabling the vehicle key through the remote key management APP, then sending the ID of the key and the key disabling request to the data processing device through the remote key management APP, and then sending the ID of the key and the key disabling request to the key management system through the data processing device, so that the key management system executes the operation of disabling the vehicle key and sends the enabling state of the disabled key to the data processing device. The enabling state of the disabled key and the disabling trigger method are saved to the non-volatile memory of the vehicle through the data processing device. At the same time, the enabling state of the disabled key is sent to the remote key management APP through the data processing device, and the enabling state of the disabled key is displayed in the remote key management APP. If a request such as starting the vehicle, unlocking the whole vehicle, locking the whole vehicle, or opening the vehicle door is made using the disabled key, a judgment of not responding to the request can be made through the data processing device according to the enabling state of the disabled key, thus avoiding vehicle theft.

[0048] Among them, the disabling trigger methods include two types: remote disabling and local disabling. Remote disabling means disabling the lost key on the remote key management APP, and local disabling means automatically disabling the remaining key in the vehicle after the vehicle is locked through an external method. After the vehicle key is locally disabled, the enabling status of the disabled key will be sent to the remote key management APP through the data processing device, and the enabling status of the disabled key will be displayed in the remote key management APP.

[0049] When the disabling trigger method of the disabled key is remote disabling, the vehicle key can be unlocked on the remote key management APP. The specific operations can include: receiving the operation to unlock the vehicle key through the remote key management APP, then sending the ID of the key and the key unlocking request to the data processing device through the remote key management APP, and then sending the ID of the key and the key unlocking request to the key management system through the data processing device, so that the key management system performs the operation of unlocking the vehicle key and sends the enabling status of the unlocked key to the data processing device. The enabling status of the unlocked key is saved to the non-volatile memory of the vehicle through the data processing device. At the same time, the enabling status of the unlocked key is sent to the remote key management APP through the data processing device, and the enabling status of the unlocked key is displayed in the remote key management APP.

[0050] When the disabling trigger method of the disabled key is local disabling, if the vehicle meets the preset unlocking conditions, the ID of the disabled key and the key unlocking request are sent to the key management system through the data processing device, so that the key management system performs the operation of unlocking the vehicle key and sends the enabling status of the unlocked key to the data processing device. The enabling status of the unlocked key is saved to the non-volatile memory of the vehicle through the data processing device. At the same time, the enabling status of the unlocked key is sent to the remote key management APP through the data processing device, and the enabling status of the unlocked key is displayed in the remote key management APP.

[0054] The system may further include: An unlocking module, configured to perform an unlocking operation on the disabled legacy key and control switch when the vehicle meets a preset unlocking condition. The legacy key disabling module 2 may include the following sub-modules: A key disabling sub-module, configured to disable the legacy key in the vehicle when there is a legacy key in the vehicle during the detection period and the vehicle does not meet any of the conditions of vehicle unlocking, the vehicle mode is switched to a preset convenience mode, activation mode, or driving mode, and a preset first in-vehicle switch is turned on.

[0055] The control switch disabling module 3 may include the following sub-modules: A switch disabling sub-module, configured to disable the door switch, front hood switch, trunk switch, and glove box switch in the vehicle when the vehicle meets a preset second disabling condition during the detection period.
