Abstract
Description
Technical Field
[0001] This application relates to the field of automotive anti-theft technology, specifically to the field of a locator-based automotive anti-theft system. Background Technology
[0002] In the field of car anti-theft, traditional anti-theft systems mainly rely on mechanical locks, electronic alarm devices, and remote control units to protect vehicles from theft. These systems typically include sensors (such as vibration sensors and tilt sensors) installed inside or outside the vehicle, connected to alarms, and remote keys owned by the vehicle owner.
[0003] Traditional anti-theft systems focus on preventing theft in the first place, offering limited assistance once a vehicle is stolen. One significant problem is the difficulty in locating the vehicle: recovering a stolen vehicle can be extremely challenging. Furthermore, most anti-theft systems' remote keys only function within a short range, losing signal beyond that distance.
[0004] If the remote key is lost or damaged, regaining access to the vehicle can become complicated. In terms of security, despite the introduction of various encryption technologies and rolling code mechanisms to prevent copying attacks, the risk of cracking remains, especially when facing professional thieves. Utility Model Content
[0005] To address the aforementioned issues, this application proposes a locator-based car anti-theft system. By utilizing the technical features of AirTag, AirTag is embedded into the car anti-theft system, providing users with a more intelligent, secure, and convenient solution.
[0006] To achieve the above objectives, the present application adopts the following technical solution:
[0007] A locator-based car anti-theft system includes an anti-theft device equipped with a power supply circuit, the anti-theft device being built into the car;
[0008] A battery-powered remote control that can control the anti-theft device;
[0009] The first AirTag module is built into the anti-theft device and is powered by the power supply circuit.
[0010] This application simplifies the usage process by embedding a first AirTag module in the anti-theft device and powering it with its power circuit. Car owners do not need to carry additional tracking devices. By utilizing the precise positioning capabilities of AirTag and Apple's "Find My" network, the vehicle's location can be easily found even in the absence of GPS coverage.
[0011] Meanwhile, a wide-ranging private network ensures that any Bluetooth-enabled Apple device can anonymously help detect and report vehicle location, increasing the likelihood of recovering stolen vehicles.
[0012] In some possible implementations, a second AirTag module disposed within the remote controller is also included, the second AirTag module being powered by the battery.
[0013] By embedding a second AirTag module into the remote control, car owners can not only track the vehicle's location but also monitor the remote control's status in real time. If the remote control is lost or stolen, the owner can quickly locate and retrieve it through the "Find My" app. This not only protects important control devices but also prevents potential security risks, such as unauthorized vehicle access.
[0014] Furthermore, the second AirTag module enhances the redundancy and reliability of the overall system. Even if the first AirTag module of the anti-theft device malfunctions, the second AirTag module in the remote control can still provide location information, ensuring the vehicle remains trackable. This dual-protection mechanism significantly increases the likelihood of vehicle retrieval, especially in emergency situations.
[0015] In some preferred embodiments, the first AirTag module and the second AirTag module use Bluetooth Low Energy communication.
[0016] In some preferred embodiments, the Bluetooth Low Energy uses the 2.4 GHz band.
[0017] In some possible implementations, the anti-theft device may also include a host chip, an output drive circuit, an input conversion circuit, and wiring harness connection terminals.
[0018] In some possible implementations, the anti-theft device further includes an RF receiver module connected to the host chip, the RF receiver module being connected to an RF receiving antenna.
[0019] In some possible implementations, the remote controller may also include a remote control encoding chip.
[0020] In some possible implementations, the remote controller further includes an RF transmitting circuit connected to a remote control encoding chip, the RF transmitting circuit being connected to a PCB antenna. Attached Figure Description

[0026] Figure 6 This is the second application example of the car anti-theft system in this application. Detailed Implementation
[0027] The following examples further illustrate the features of this application and other related features in detail, so as to facilitate understanding by those skilled in the art:
[0028] First, a car alarm is an electronic device installed in a vehicle to prevent unauthorized personnel from starting or moving the vehicle. It is typically concealed inside the passenger compartment or engine compartment. These locations not only facilitate connection to the vehicle's electrical system but also make it difficult to detect or damage from the outside. In other words, the car alarm is built into the car.
[0029] In contrast, a remote control is a portable electronic device that controls an anti-theft system, allowing users to control certain functions of a car from a distance. It communicates with the car wirelessly, and its most common applications are unlocking and locking the doors. The remote control can also be used to make the vehicle honk and flash its turn signals to indicate its location and facilitate locating the vehicle.
[0030] The AirTag module is an accessory designed specifically for tracking personal items. It incorporates a U1 chip (UltraWideband technology) for accurate location detection and utilizes Bluetooth Low Energy technology to communicate with other devices. AirTag is designed with privacy and security in mind, employing anonymously encrypted broadcast messages to ensure secure transmission of location information.
[0031] Ultra-Wideband (U1) chip: On compatible Apple devices, such as iPhone 11 and later models, the U1 chip provides more precise spatial awareness, allowing users to find the exact location of their AirTag using the "Precise Find" feature.
[0032] Bluetooth Low Energy (BLE): AirTag uses BLE technology for short-range wireless communication. This connection method is low-power, low-cost, and widely used in various IoT devices. BLE devices can broadcast information and establish connections with other compatible devices without direct pairing or displaying in the Bluetooth device list.
[0033] 2.4GHz band: BLE operates on this band, which is also used for other wireless technologies such as Wi-Fi and Zigbee. This means that AirTag can communicate using ubiquitous infrastructure without interfering with other devices using the same frequency band.
[0034] Find My Network Protocol: This is a private network of hundreds of millions of Apple devices, all of which anonymously help locate lost items joined to the network. The network operates based on Bluetooth discovery and location sharing, but fully respects user privacy and does not disclose any personal information.
[0035] iCloud is a cloud service provided by Apple for data backup, synchronization, and support for features such as Find My. With iCloud, even if your device is not with you, you can log in to other Apple devices or visit icloud.com to locate lost items or devices.
[0036] AirTags themselves don't connect directly to the internet; instead, they rely on a global, private network of nearby Apple devices—the "Find My" network. Any Bluetooth-enabled Apple device can anonymously detect and report the location of nearby AirTags to iCloud without draining its own battery. This information is encrypted and location updates are only provided to the AirTag's owner.
[0037] Please refer to Figure 1 and Figure 2 This case discloses a car anti-theft system based on a locator, which includes an anti-theft device 1 equipped with a power circuit, as described above, the anti-theft device 1 being built into the car. A remote control 2 is paired with it, the remote control 2 being able to control the anti-theft device 1.
[0038] The anti-theft device 1 includes a main chip, an output drive circuit, an input conversion circuit, and wiring harness connection terminals. As a connection method with the remote control 2, it includes an RF receiver module connected to the main chip, and the RF receiver module is connected to an RF receiving antenna.
[0039] The remote control 2 includes a battery and a remote control encoding chip. As a connection method with the anti-theft device 1, it includes an RF transmitting circuit connected to the remote control encoding chip, and the RF transmitting circuit is connected to a PCB antenna.
[0040] Please refer to reference 3 for the anti-theft device 1 built into the car. The anti-theft device 1 has a built-in locator, which is a first AirTag module. The first AirTag module is powered by the power circuit.
[0041] This application simplifies the usage process by embedding a first AirTag module in the anti-theft device and powering it with its power circuit. Car owners do not need to carry additional tracking devices. They can simply use their mobile phones to locate the vehicle using the precise positioning capabilities of AirTag and Apple's "Find My" network, making it easy to find the vehicle's location even in the absence of GPS coverage.
[0042] Furthermore, a locator can also be built into the remote controller 2. The locator built into the remote controller 2 is a second AirTag module, which is powered by the battery.
[0043] Specifically, the first AirTag module and the second AirTag module use Bluetooth Low Energy communication. Preferably, the Bluetooth Low Energy communication uses the 2.4GHz frequency band.
[0044] Please refer to Figure 3 and Figure 4 At this point, the owner's iPhone 3 first uses the "Find My" app to connect via Bluetooth to the first AirTag module. When the car is locked and the owner leaves the Bluetooth Low Energy range of the first AirTag module (e.g., within 50 meters), a location will be marked. The owner's iPhone 3's own GPS generates the location information and saves it in the "Find My" app. At this point, the owner's iPhone 3 is in a pre-bound locator ID state.
[0045] If parking guidance is unavailable in a large shopping mall, when looking for a parking spot, you can first use the "Find My" app on your iPhone (phone 3) to locate the car within the Bluetooth Low Energy range of the first AirTag module. Then, use the remote control (phone 2) to sound the beep to locate the car.
[0046] Meanwhile, a wide-ranging private network ensures that any Bluetooth-enabled Apple device can anonymously help detect and report vehicle location, increasing the likelihood of recovering stolen vehicles.
[0047] Please refer to Figure 5 For example, once the first AirTag module is marked as lost (e.g., the user selects "Lost Mode" in the "FindMy" app), it begins sending encrypted Bluetooth signals. These signals contain unique but anonymous information that identifies the AirTag.
[0048] When a passerby's iPhone 5 or other Bluetooth-enabled Apple device, such as a watch, tablet, or laptop (even if they are not the owner of the AirTag), enters the Bluetooth range of the first AirTag module, these devices can detect the Bluetooth signal from the first AirTag module.
[0049] The device that detects the signal from the first AirTag module will transmit the ID and location information of the first AirTag module back to the iCloud cloud via end-to-end encryption. At this time, the location information may be determined by GPS, cell towers, or IP addresses.
[0050] During this process, all data is processed anonymously to ensure user privacy is not violated. Only the registered owner of the first AirTag module, i.e., the car owner's phone number 3 bound to the locator ID, can view this new location information in their "Find My" application. The "Find My" application is the query function app described above.
[0051] Once the location information is uploaded to iCloud and verified, the owner of the first AirTag module will receive a notification informing them that the lost first AirTag module has been found and providing the latest location information.
[0052] Please refer to Figure 6 Another application example is the use of a second AirTag module built into the remote control 2. This allows the owner to not only track the vehicle's location but also monitor the status of the remote control 2 in real time. If the remote control 2 is lost or stolen, the owner can quickly locate and retrieve it using the "Find My" app via a passerby's mobile phone 5 and its new location uploaded to the iCloud cloud 4. This not only protects important control devices but also prevents potential security risks, such as unauthorized vehicle access.
[0053] Furthermore, the second AirTag module enhances the redundancy and reliability of the overall system. Even if the first AirTag module of the anti-theft device 1 malfunctions, the second AirTag module in the remote control 2 can still provide location information, ensuring that the vehicle is always trackable. This dual-protection mechanism significantly increases the likelihood of recovering the vehicle, especially in emergency situations.
[0054] As stated above, this application protects a car anti-theft system based on a locator, and all technical solutions that are the same as or similar to this application should be considered to fall within the scope of protection of this application.
