For the engine / drive motor anti-theft system, if the vehicle is unlocked or the door is illegally opened, it can also be towed away by using another vehicle. Therefore, the anti-theft system in the relevant technology can no longer meet people's security needs for vehicle anti-theft. Summary of the invention

DETAILED DESCRIPTION

[0036] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0037] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the present invention should be understood by people with ordinary skills in the field to which the present invention belongs. The "first", "second" and similar words used in the present invention do not indicate any order, quantity or importance, but are only used to distinguish different components. "Include" or "comprise" and similar words mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects. "Connect" or "connected" and similar words are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0038] As described in the background technology section, since the relevant anti-theft technology does not have the function of locking the vehicle wheels, criminals usually only need to pry open the mechanical lock of the car door to tow the car away or directly start the engine and drive away the vehicle. Even if the engine / drive motor is equipped with an anti-theft system, if the vehicle wheels can turn, criminals can also tow the stolen vehicle away by towing, and the vehicle cannot be completely protected from theft.

[0039] In the process of implementing the present invention, the applicant discovered that the anti-theft security of the vehicle can be upgraded by locking the wheels of the vehicle and ensuring that the request to unlock the vehicle is legal through a dual authentication method of security authentication and anti-theft authentication. Further, based on the legal unlocking request, the brakes on the vehicle's wheels and engine / drive motor are released, which can effectively improve the anti-theft security of the vehicle without increasing additional costs.

[0040] The technical solution of the present invention is further described in detail below through specific embodiments.

[0041] refer to Figure 1 , is a structural diagram of an EMB-based vehicle intelligent anti-theft system 100 provided in an embodiment of the present invention.

[0042] According to the EMB-based vehicle intelligent anti-theft system 100 provided in an embodiment of the present invention, the system includes a body controller 30 , a brake controller 60 , a brake mechanism 70 , an anti-theft controller 20 , a starting device 10 , a power controller 40 and a power mechanism 50 . Among them, the body controller 30 is used to perform anti-theft authentication with the brake controller 60 after receiving the authentication pass information sent by the anti-theft controller 20; the brake controller 60 is used to control the brake mechanism 70 to unlock after the anti-theft authentication with the body controller 30 is passed, so as to release the brake on the wheels of the target vehicle; the anti-theft controller 20 is used to receive the unlocking signal sent by the starting device 10, and perform security encryption authentication with the starting device 10 according to the unlocking signal, and after the security encryption authentication with the starting device 10 is passed, the authentication pass information is sent to the body controller 30; the starting device 10 is used to send an unlocking signal to the anti-theft controller 20; the body controller 30 is used to perform anti-theft authentication with the power controller 40 after receiving the authentication pass information sent by the anti-theft controller 20; the power controller 40 is used to control the power mechanism 50 to unlock after the anti-theft authentication with the body controller 30 is passed, so as to release the brake on the engine of the target vehicle.

[0043] Specifically, the starting device 10 can be a traditional ignition key. There is an embedded transceiver chip inside the starting device 10, and it is also equipped with a low-frequency antenna for low-frequency wireless communication with the anti-theft controller 20. The low-frequency wireless communication has strong anti-interference ability, low cost and strong penetration ability, so that the starting device 10 can smoothly send the unlocking signal to the anti-theft controller 20.

[0044] It should be noted that the starting device 10 can also be based on biometrics (such as fingerprint recognition, facial recognition, etc.), smart electronic devices (such as mobile phones and watches, etc.) and near-field communication (NFC), etc. According to the starting method of different starting devices 10, the setting method of the transceiver chip and the low-frequency antenna can be adjusted accordingly.

[0045] The anti-theft controller 20 is arranged inside the body of the target vehicle, and can detect and respond to illegal connection and other behaviors. It includes an anti-theft coil driver chip, which can drive the anti-theft coil to work. When a metal object (such as a theft tool or a metal part of the human body) approaches the anti-theft coil, the magnetic field in the coil will change, and this change can be converted into an electrical signal, thereby triggering an alarm. The anti-theft controller 20 also includes a transceiver chip. After receiving the unlocking signal sent by the starting device 10, the anti-theft controller 20 performs security encryption authentication with the starting device 10. Security encryption authentication is usually implemented using an encryption algorithm (such as a symmetric encryption algorithm or an asymmetric encryption algorithm) and a key management system. During the authentication process, the anti-theft controller 20 and the starting device 10 will share a set of keys (such as a symmetric key), and the key is used to encrypt and decrypt the unlocking signal. Further, the anti-theft controller 20 will verify whether the received unlocking signal is authentic and valid, which can be achieved by comparing the hash value or digital signature of the encrypted data. If the unlocking signal verification is successful, the anti-theft controller 20 can consider that the starting device 10 is legal, that is, the starting device 10 passes the encryption authentication, and further sends the authentication pass information to the body controller 30.

[0046] It should be noted that the vehicle body controller 30 and the anti-theft controller 20 may be connected by hard wires, which can also effectively avoid external interference and ensure that signals can be accurately transmitted between the vehicle body controller 30 and the anti-theft controller 20 .

[0047] After receiving the authentication pass information sent by the anti-theft controller 20, the body controller 30 performs anti-theft authentication on the brake controller 60 through CAN communication, wherein the anti-theft authentication includes key authentication and security code authentication. When the anti-theft authentication of the brake controller 60 and the body controller 30 is passed, the brake controller 60 controls the brake mechanism 70 to release the brakes on the wheels of the target vehicle so that the target vehicle can start normally.

[0048] The brake controller 60 may be an EMB (Electromechanical Brake), which can control the brake mechanism 70 of the target vehicle to brake the wheels through electrical signals. The EMB may be composed of an electronic control unit and an electric actuator, etc., wherein the electronic control unit is responsible for receiving various data or signals, and sending corresponding instructions to the electric actuator according to the data or signals, so that the electric actuator brakes or releases the brakes.

[0049] It should be noted that key authentication can ensure that only devices or personnel holding legal keys can access the system. One or more preset keys are stored in the body controller 30 and the brake controller 60. When anti-theft authentication is required, the body controller 30 will send a request containing a key to the brake controller 60. After receiving the request, the brake controller 60 will use its own stored key for matching and authentication. If the key match is successful, the body authentication is passed. If the key match fails, the body authentication fails. The combination of security code authentication and key authentication can provide higher security for authentication. During the security code authentication process, one or more security codes will be exchanged between the body controller 30 and the brake controller 60 to verify each other's identity and authorization status. Among them, the security code can be a dynamic code generated based on a specific algorithm or a preset static code. If the security code matches successfully, the anti-theft authentication is passed. If the security code matches fail, the anti-theft authentication fails. When both the key authentication and the security code authentication are passed, the brake controller 60 allows the body controller 30 to perform subsequent operations. When at least one of the key authentication and the security code authentication fails, the brake controller 60 will reject the access request of the body controller 30.

[0050] refer to Figure 2 , is a schematic structural diagram of a brake mechanism 70 provided in an embodiment of the present invention.

[0051] As an optional embodiment, the braking mechanism 70 includes: a wheel-end motor 710, which is arranged corresponding to the tire of the target vehicle; a brake disc 730, which is arranged on the wheel hub of the target vehicle; a brake caliper 720, which is connected to the wheel-end motor 710; the wheel-end motor 710 is connected to the brake controller 60, and is used to control the brake caliper 720 and the brake disc 730 to release the pressure contact after the anti-theft authentication of the brake controller 60 and the body controller 30 is passed, so as to release the brake on the wheel of the target vehicle.

[0052] Specifically, at least one tire of the target vehicle is provided with a brake mechanism 70. When the wheels of the target vehicle are in a locked state, the wheels will be locked and cannot rotate.

[0053] The brake mechanism 70 includes a wheel-end motor 710, a brake caliper 720 and a brake disc 730. The wheel-end motor 710 is also called a wheel hub motor or a wheel-side motor. It is a driving device that directly transmits power to the wheel. In addition to driving the wheel forward, the wheel-end motor 710 can also produce a braking effect on the wheel. The brake caliper 720 contains components such as a piston, a friction plate, and related oil circuits and return mechanisms. The oil circuit ensures that the brake oil can smoothly transmit hydraulic pressure to the piston so that the piston can push the friction plate to contact the brake disc. The brake disc 730 is a disc-shaped component that rotates with the wheel and is usually made of high-strength alloy. When the brake pads of the brake caliper 720 clamp the brake disc 730, the friction between the two will slow down the rotation speed of the wheel, thereby achieving a braking effect.

[0054] The wheel-end motor 710 is arranged corresponding to the tire provided on the brake mechanism 70 of the target vehicle. When the wheel of the target vehicle is in a locked state, the locking clutch of the wheel-end motor 710 is in a locked state, and the wheel-end motor 710 pushes forward to make the locking clutch contact with the brake caliper 720, and sufficient friction is generated through the friction material on the locking clutch and the brake caliper 720, so that the locking clutch and the brake caliper 720 are tightly connected together; further, after the brake caliper 720 is pushed by the wheel-end motor 710, the friction plate on the brake caliper 720 contacts with the brake disc 730, and a locking braking force is generated on the brake disc 730.

[0055] It should be noted that the connection between the brake controller 60 and the wheel-end motor 710 can be controlled by a hard-wired connection, which can effectively avoid external interference. When the anti-theft authentication of the brake controller 60 and the body controller 30 is passed, the brake controller 60 controls the release of the wheel lock by the locking clutch, that is, the wheel-end motor 710 withdraws the forward-moving locking clutch, and further realizes the release of the pressure contact between the brake caliper 720 and the brake disc 730 to release the brakes on the wheels of the target vehicle. At this time, the brake controller 60 is in normal parking mode, and the target vehicle can operate the electronic parking brake system (i.e., electronic handbrake) after ignition to release the parking mode, so that the target vehicle can drive normally.

[0056] After receiving the authentication pass information sent by the anti-theft controller 20, the body controller 30 also performs anti-theft authentication on the power controller 40 through CAN communication, wherein the anti-theft authentication also includes key authentication and security code authentication. When the anti-theft authentication of the power controller 40 and the body controller 30 is passed, the power controller 40 controls the power mechanism 50 to release the brakes on the engine of the target vehicle so that the target vehicle can start normally.

[0057] The power controller 40 is a key component for controlling the driving of the vehicle. The power controller 40 collects the working status data of the engine in real time by integrating various sensors, and converts it into electrical signals to further control the vehicle. When the anti-theft authentication of the power controller 40 and the body controller 30 is passed, the power controller 40 can control the triggering of the electronic switch to unlock the engine, and further adjust the engine's ignition and injection parameters to enable the engine to work normally.

[0058] It should be noted that when both the key authentication and the security code authentication are passed, the power controller 40 allows the body controller 30 to perform subsequent operations. When at least one of the key authentication and the security code authentication fails, the power controller 40 will reject the access request of the body controller 30.

[0059] It should be noted that the body controller 30 performs anti-theft authentication on the brake controller 60 and the power controller 40 simultaneously through CAN communication. If at least one of the brake controller 60 or the power controller 40 fails the anti-theft authentication, the body controller 30 is prohibited from controlling the normal start of the target vehicle.

[0060] As an optional embodiment, the power controller 40 is further configured to respond to a start instruction for the target vehicle when the brakes on the wheels of the target vehicle and the brakes on the engine of the target vehicle are released.

[0061] Specifically, when the wheel brakes of the target vehicle and the engine brakes of the target vehicle are released, the power controller 40 responds to the start command to control the operation of the engine or drive motor and the transmission system, including but not limited to adjusting the engine speed, engine output power and transmission ratio parameters of the transmission system, so that the target vehicle can start and accelerate smoothly and safely to adapt to different driving conditions and requirements.

[0062] As an optional embodiment, the power controller 40 is also used to refuse to respond to the start-up instruction for the target vehicle when the security encryption authentication and / or the anti-theft authentication fails.

[0063] Specifically, when the security encryption authentication and / or anti-theft authentication fails, the power controller 40 executes a refusal to respond to the start instruction, that is, it does not control the operation of the engine or the drive motor and the transmission system. When the security encryption authentication fails, the anti-theft controller 20 will refuse to transmit the unlocking signal to the body controller 30. Furthermore, if an interference signal appears at this time to cause the body controller 30 to perform anti-theft authentication on the power controller 40, at this time, even if the anti-theft authentication of the power controller 40 and the body controller 30 can be passed, the power controller 40 will also refuse to respond to the start instruction; the situation where the anti-theft authentication fails includes the anti-theft authentication of the power controller 40 and the body controller 30 fails and the anti-theft authentication of the brake controller 60 and the body controller 30 fails. When any one of the above two anti-theft authentications fails, the power controller 40 executes a refusal to respond to the start instruction.

[0064] From the above description, it can be seen that the vehicle intelligent anti-theft system based on EMB provided by the present invention, when the vehicle is in a locked state, needs to pass the security authentication of the ignition device and the anti-theft controller, and further pass the anti-theft authentication of the body controller, the brake controller and the power controller before the wheel brakes of the target vehicle can be released. Through a simple authentication mechanism, it can ensure that the vehicle only responds to legitimate unlocking requests, which effectively improves the anti-theft security of the vehicle without increasing additional costs and is not easily interfered with.

[0065] Based on the same inventive concept, corresponding to the vehicle intelligent anti-theft system based on EMB provided in any of the above embodiments, the present invention further provides a vehicle intelligent anti-theft method based on EMB.

[0066] refer to Figure 3 , which is a flow chart of the vehicle intelligent anti-theft method based on EMB provided in an embodiment of the present invention.

[0067] Step S301, after receiving the authentication pass information sent by the anti-theft controller, perform anti-theft authentication with the brake controller;

[0068] Step S302, after the anti-theft authentication with the brake controller is passed, the brake controller controls the brake mechanism to unlock, so as to release the brakes on the wheels of the target vehicle;

[0069] Step S303, after receiving the authentication pass information sent by the anti-theft controller, perform anti-theft authentication with the power controller;

[0070] Step S304, after the anti-theft authentication with the power controller is passed, the power mechanism is controlled to be unlocked by the power controller to release the brake on the engine of the target vehicle.

[0071] Specifically, the starting device sends an unlocking signal to the anti-theft controller through low-frequency wireless communication. After receiving the unlocking signal, the anti-theft controller performs security encryption authentication with the starting device according to the unlocking signal. When the anti-theft controller and the starting device pass the security encryption authentication, the authentication pass information is sent to the body controller through a hard line; after receiving the authentication pass information, the body controller simultaneously sends an anti-theft authentication to the brake controller and the power controller through CAN communication, wherein the anti-theft authentication includes a key authentication and a security code authentication. When both the brake controller and the power controller pass the anti-theft authentication, the brake controller controls the brake mechanism to unlock and release the brakes on the target vehicle wheels, and the power controller controls the power mechanism to unlock and release the brakes on the target vehicle engine. Furthermore, the body controller switches from the locking mode to the parking mode, so that the vehicle can normally operate the electronic parking brake system to release the parking after ignition, so that the target vehicle can drive normally.

[0072] From the above description, it can be seen that the vehicle intelligent anti-theft method based on EMB provided by the present invention, when the vehicle is in a locked state, needs to pass the security authentication of the ignition device and the anti-theft controller, and further pass the anti-theft authentication of the body controller, the brake controller and the power controller before the wheel brakes of the target vehicle can be released. Through a simple authentication mechanism, it can ensure that the vehicle only responds to legitimate unlocking requests, which effectively improves the anti-theft security of the vehicle without increasing additional costs and is not easily interfered with.

[0073] It should be noted that the vehicle intelligent anti-theft method based on EMB in the embodiment of the present invention can be executed by a single device, such as a computer or server. The vehicle intelligent anti-theft method based on EMB in this embodiment can also be applied to a distributed scenario and completed by multiple devices cooperating with each other. In the case of such a distributed scenario, one of the multiple devices can only execute one or more steps in the vehicle intelligent anti-theft method based on EMB in the embodiment of the present invention, and the multiple devices will interact with each other to complete the above-mentioned vehicle intelligent anti-theft method based on EMB.

[0074] It should be noted that some embodiments of the present invention are described above. Other embodiments are within the scope of the appended claims. In some cases, the actions or steps recorded in the claims can be performed in an order different from that in the above embodiments and still achieve the desired results. In addition, the processes depicted in the accompanying drawings do not necessarily require the specific order or continuous order shown to achieve the desired results. In some embodiments, multitasking and parallel processing are also possible or may be advantageous.

[0075] Based on the same inventive concept, corresponding to the vehicle intelligent anti-theft system based on EMB provided in any of the above embodiments, the present invention further provides a vehicle intelligent anti-theft device based on EMB.

[0076] refer to Figure 4 , is a schematic diagram of an EMB-based vehicle intelligent anti-theft device provided in an embodiment of the present invention.
