A method for remotely locking a vehicle to prevent cracking

Abstract

The present invention discloses an anti-cracking remote vehicle locking method, comprising a vehicle locking platform module, a T-BOX module, a Bluetooth transmitting module, a combination meter, a Bluetooth receiving module and a VCU module. The vehicle locking platform module is connected to the T-BOX module via a mobile wireless network, and the T-BOX module is connected to the combination meter and the VCU module via a CAN bus. The present invention can crack the problem that the T-BOX module of a vehicle-mounted wireless terminal is artificially wrapped by a shielding layer, which prevents the vehicle locking platform module from sending a vehicle locking instruction to the T-BOX module, thereby preventing a malicious delay in vehicle use or an escape from the installment purchase payment operation by a car rental customer or a car purchase customer who has not repaid the installment by artificially wrapping the shielding layer outside the T-BOX module, thereby ensuring that the vehicle locking platform module can safely supervise the vehicle use restrictions of the car rental customer or the car purchase customer who has not repaid the installment and perform vehicle locking control, thereby effectively preventing a car sales company or an installment purchase operation platform from incurring large property losses.

Description

Technical Field

[0001] The present invention relates to the technical field of remote car locking, and in particular to an anti-cracking remote car locking method. Background Art

[0002] Remote vehicle locking is achieved by the platform sending a lock or unlock command to the on-board wireless mobile terminal (T-box) through wireless transmission. The T-box sends a lock / unlock command to the engine ECU or vehicle controller VCU based on the command to limit the vehicle's power performance or remove the vehicle's power performance restrictions. Since it is remote locking, the lock command must be issued through wireless transmission. Remote vehicle locking is an important technical guarantee for car companies or car rental operating platforms to constrain target customers or car rental customers who pay in installments to pay on time.

[0003] At present, the locking process and T-box anti-disassembly technology are relatively mature and reliable, but the platform's instructions must be sent to the T-box through wireless transmission. Since wireless transmission is restricted by terrain and region, it may not be able to connect to the vehicle terminal normally all the time. There is also the risk of artificial shielding of wireless transmission. It is difficult for the platform to distinguish whether it is geographical restrictions that make it impossible to connect to the platform or artificial shielding of the wireless signal to connect to the platform. In particular, the act of artificially shielding wireless transmission makes it impossible to lock the car according to the instructions, which can easily lead to the loss of the vehicle or the theft of items in the car. This will cause greater property losses to the car company platform or the car rental operation platform that remotely locks the car. For this reason, we propose a remote car locking method that is anti-cracking. Summary of the invention

[0004] The main purpose of the present invention is to provide an anti-cracking remote car locking method, by building a Bluetooth transmitting module into a T-BOX module and setting a Bluetooth receiving module inside a combination instrument. Since the display information of the combination instrument is important to the driver and its installation position is special and cannot be artificially wrapped by a shielding layer, after the T-BOX module fails to wirelessly connect to the platform, the internal Bluetooth transmitting module is turned on, and the combination instrument is required to connect its own Bluetooth signal through a request message. If the combination instrument can establish a connection with itself, it means that the T-BOX module is not artificially wrapped by a shielding layer. If the combination instrument cannot establish a connection with itself, it means that it is artificially wrapped by a shielding layer. The combination instrument sends Bluetooth connection information to the T-BOX module through a message. The T-BOX module determines whether the reason why it cannot connect to the platform is artificially shielded based on this information, and thus decides whether to issue a car locking instruction to the VCU, thereby realizing an anti-cracking remote car locking method, effectively ensuring the vehicle locking management of the car enterprise platform or the car rental operation platform, and effectively solving the problems in the background technology.

[0005] To achieve the above object, the technical solution adopted by the present invention is:

[0006] A method for remotely locking a vehicle against cracking comprises a vehicle locking platform module, a T-BOX module, a Bluetooth transmitting module, a combination meter, a Bluetooth receiving module and a VCU module. The vehicle locking platform module is connected to the T-BOX module via a mobile wireless network. The T-BOX module is connected to the combination meter and the VCU module via a CAN bus. The T-BOX module and the combination meter are respectively provided with a Bluetooth transmitting module and a Bluetooth receiving module. The T-BOX module and the combination meter perform handshake verification each time they are powered on. The T-BOX module and the VCU module perform handshake verification each time they are powered on. If any one of the combination meter or the T-BOX module is removed, the VCU module executes a vehicle locking instruction to restrict the start-up or power output of the entire vehicle.

[0007] Furthermore, the Bluetooth transmitter module is built-in and installed in the T-BOX module;

[0008] By adopting the above technical solution, the Bluetooth transmitter module is not easily discovered in the T-BOX module.

[0009] Furthermore, the Bluetooth receiver module is built-in and installed in the instrument cluster;

[0010] By adopting the above technical solution, the Bluetooth receiving module is not easily discovered in the instrument cluster.

[0011] Further, the workflow includes the following:

[0012] S1. N seconds after the vehicle is powered on, the VCU module first sends a seed message to the T-BOX module through the CAN bus for handshake verification. After receiving the seed message information, the T-BOX module needs to reply with a key message within the specified time according to the agreed encryption method. The VCU module verifies whether the key is correct. If it is correct, it proceeds to the next step. If it is incorrect, it executes the vehicle locking strategy. The VCU module can send the seed message N times according to the agreement. If it does not receive the key message from the T-BOX module after sending N times, it executes the vehicle locking strategy.

[0013] S2. After the T-BOX module feeds back the seed message from the VCU module, it sends a seed message to the instrument cluster through the CAN bus for handshake verification. After receiving the seed message information, the instrument cluster needs to reply with a key message within the specified time according to the agreed encryption method. The T-BOX module verifies whether the key is correct. If it is correct, it proceeds to the next step. If it is incorrect, it sends a car lock command to the VCU module, and the VCU module executes the car lock strategy. According to the agreement, the T-BOX module sends the seed message N times. If it does not receive the key message from the instrument cluster after sending N times, it sends a car lock command to the VCU module, and the VCU module executes the car lock strategy.

[0014] S3. After the T-BOX module successfully handshakes with the VCU module and the instrument cluster, it starts to connect to the vehicle locking platform module. If it can connect to the vehicle locking platform module, it checks whether there is a vehicle locking / unlocking instruction from the vehicle locking platform module. If so, it sends a vehicle locking / unlocking instruction to the VCU module. The VCU module executes the vehicle locking / unlocking strategy. If the connection with the platform fails, it proceeds to the next step.

[0015] S4. After the T-BOX module fails to connect to the vehicle locking platform module, it turns on the Bluetooth transmitter in its own device and sends a request message to the instrument cluster through the CAN bus at the same time, requesting the instrument cluster to turn on its own Bluetooth receiving module and connect according to the set matching password. After trying N times, it sends a Bluetooth connection status information message to the T-BOX module through the CAN bus. The T-BOX module determines whether it is artificially wrapped in a shielding layer based on the message information;

[0016] S5. If the message information shows that the Bluetooth connection is successful, it means that the T-BOX module itself is not shielded and does not send a car lock command to the VCU module. After waiting for N hours, repeat step S4. If the message information shows that the Bluetooth connection is unsuccessful, it means that the T-BOX module itself is wrapped in a shielding layer and the wireless transmission is artificially destroyed. The T-BOX module sends a car lock execution to the VCU module, and the VCU module executes the car lock strategy.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The present invention can crack the problem that the T-BOX module of the on-board wireless terminal is artificially wrapped in a shielding layer, which hinders the car locking platform module from sending a car locking instruction to the T-BOX module, thereby preventing car rental customers or customers who have not repaid their installment purchases from maliciously delaying the use of the vehicle or escaping from the installment purchase payment operation by artificially wrapping the shielding layer outside the T-BOX module, ensuring that the car locking platform module can safely monitor the vehicle use restrictions of car rental customers or customers who have not repaid their installment purchases and perform car locking control, effectively avoiding large property losses incurred by car sales companies or installment purchase operation platforms.

[0026] By adopting the above technical solution, the Bluetooth receiving module is not easily discovered in the instrument cluster.

[0027] The present invention is a method for remotely locking a vehicle to prevent cracking, and the specific working process is as follows:

[0028] S1. N seconds after the vehicle is powered on, the VCU module first sends a seed message to the T-BOX module through the CAN bus for handshake verification. After receiving the seed message information, the T-BOX module needs to reply with a key message within the specified time according to the agreed encryption method. The VCU module verifies whether the key is correct. If it is correct, it proceeds to the next step. If it is incorrect, it executes the vehicle locking strategy. The VCU module can send the seed message N times according to the agreement. If it does not receive the key message from the T-BOX module after sending N times, it executes the vehicle locking strategy.

[0029] S2. After the T-BOX module feeds back the seed message from the VCU module, it sends a seed message to the instrument cluster through the CAN bus for handshake verification. After receiving the seed message information, the instrument cluster needs to reply with a key message within the specified time according to the agreed encryption method. The T-BOX module verifies whether the key is correct. If it is correct, it proceeds to the next step. If it is incorrect, it sends a car lock command to the VCU module, and the VCU module executes the car lock strategy. According to the agreement, the T-BOX module sends the seed message N times. If it does not receive the key message from the instrument cluster after sending N times, it sends a car lock command to the VCU module, and the VCU module executes the car lock strategy.

[0030] S3. After the T-BOX module successfully handshakes with the VCU module and the instrument cluster, it starts to connect to the vehicle locking platform module. If it can connect to the vehicle locking platform module, it checks whether there is a vehicle locking / unlocking instruction from the vehicle locking platform module. If so, it sends a vehicle locking / unlocking instruction to the VCU module. The VCU module executes the vehicle locking / unlocking strategy. If the connection with the platform fails, it proceeds to the next step.

[0031] S4. After the T-BOX module fails to connect to the vehicle locking platform module, it turns on the Bluetooth transmitter in its own device and sends a request message to the instrument cluster through the CAN bus at the same time, requesting the instrument cluster to turn on its own Bluetooth receiving module and connect according to the set matching password. After trying N times, it sends a Bluetooth connection status information message to the T-BOX module through the CAN bus. The T-BOX module determines whether it is artificially wrapped in a shielding layer based on the message information;

[0032] S5. If the message information shows that the Bluetooth connection is successful, it means that the T-BOX module itself is not shielded and does not send a car lock command to the VCU module. After waiting for N hours, repeat step S4. If the message information shows that the Bluetooth connection is unsuccessful, it means that the T-BOX module itself is wrapped in a shielding layer and the wireless transmission is artificially destroyed. The T-BOX module sends a car lock execution to the VCU module, and the VCU module executes the car lock strategy.
