Description

Technical Field

[0001] The present application relates to the technical field of remote vehicle locking, and in particular to a remote vehicle locking system and method. Background Art

[0002] At present, the demand for remote monitoring and management of automobiles is becoming more and more common, especially for electric vehicles. In addition to national regulatory requirements, there is a need for remote monitoring and control of vehicles due to sales and operation needs. Remote locking of vehicles is an important technical guarantee for car companies or car rental operating platforms to constrain customers who make installment payments or car rental customers.

[0003] There are relatively mature solutions for TBOX (Telematics BOX, referred to as vehicle-mounted T-BOX, also known as vehicle-mounted network terminal, used to connect vehicles to external networks, usually including components such as GPS positioning system, wireless communication interface and microcontroller, which can monitor the operating status of the vehicle in real time and exchange data with other devices) anti-replacement. Each time TBOX authentication and heartbeat message detection are started, TBOX can be effectively prevented from being replaced. However, the premise of remote monitoring and control requires TBOX network access to TSP (Telematics Service Provider, automotive remote service provider, which occupies a core position in the Telematics industry chain, connected to automobiles, vehicle-mounted equipment manufacturers, network operators, and content providers) backend. Due to terrain or regional restrictions, it may not be possible to ensure real-time network smoothness. Network problems cannot be determined whether they are artificially blocked or geographically restricted. If the automatic locking function is not performed for network connection abnormalities, the TBOX will be artificially blocked from monitoring and control. If the automatic locking function is performed for network connection abnormalities, the network communication will be interrupted due to non-artificial blocking, and the automatic locking of the vehicle will make the vehicle unable to operate, which will cause customer complaints or property losses. Even if the vehicle is in a dangerous working condition, it may cause a safety accident. Summary of the invention

[0004] In view of this, the present invention provides a remote car locking system and method to solve the technical problem that when the TBOX network is lost, the prior art cannot further identify whether it is manually blocked, resulting in user complaints and property safety risks caused by wrongly locked cars.

[0006] Furthermore, the in-vehicle network terminal also includes: when the network is continuously lost for longer than a first preset time and the Bluetooth cannot communicate normally, sending a second status prompt instruction.

[0007] Furthermore, the system also includes: a central control human-computer interaction interface, which is used to receive a second prompt instruction issued by the vehicle terminal, prompting the driver that the vehicle has entered the locked mode and to use the mobile phone Bluetooth digital key to release it.

[0008] The present invention also provides a method for a remote vehicle locking system, the method comprising: step 1, the vehicle-mounted network terminal exchanges information with the remote service background system through the network, and exchanges information with the mobile phone Bluetooth digital key through Bluetooth; step 2, judging whether the network and Bluetooth are normal according to the information interaction result; step 3, when the network is continuously lost for more than a first preset time and the Bluetooth cannot communicate normally, sending a vehicle locking command to the vehicle control unit; when the network communication is normal, or the network is continuously lost for less than the first preset time, sending a normal command to the vehicle control unit; when the network is continuously lost for more than the first preset time and the Bluetooth communicates normally, sending a normal command to the vehicle control unit; when the network is continuously lost for more than the second preset time, sending a vehicle locking command to the vehicle control unit, and waiting for the network to communicate normally, going to step 2; step 4, the vehicle control unit sets the vehicle locking mode according to the vehicle locking command, and sets the normal mode according to the normal command.

[0009] Furthermore, the network is a 4G / 5G network.

[0010] Furthermore, the second preset time is greater than the first preset time.

DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] Embodiment 1: The present application provides a system and method for remotely locking a vehicle. Figure 1 As shown in FIG2 , the system includes an in-vehicle network terminal, a remote service background system, a mobile phone Bluetooth digital key and a vehicle control unit. As shown in FIG2 , the method steps are as follows.

[0018] Step 1: The vehicle network terminal exchanges information with the remote service background system through the network and exchanges information with the mobile phone Bluetooth digital key through Bluetooth; The remote service backend system is connected to the vehicle network terminal and is used to exchange information with the network communication module through the network; The mobile phone Bluetooth digital key is connected to the vehicle network terminal and is used to exchange information with the Bluetooth key control module via Bluetooth; Step 2: Determine whether the network and Bluetooth are normal based on the information interaction results; The network is typically a 4G / 5G network.

[0019] Step 3: When the network is continuously lost for more than the first preset time and the Bluetooth cannot communicate normally, a lock command is sent to the vehicle control unit; when the network communication is normal, or the network is continuously lost for less than the first preset time, a normal command is sent to the vehicle control unit; when the network is continuously lost for more than the first preset time and the Bluetooth communicates normally, a normal command is sent to the vehicle control unit; when the network is continuously lost for more than the second preset time, a lock command is sent to the vehicle control unit, and when the network communicates normally, go to step 2; The vehicle network terminal is connected to the central control human-machine interface, and is used to integrate the network communication module and the Bluetooth key control module, and respectively interact with the remote service background system and the mobile phone Bluetooth digital key to determine whether the network and Bluetooth are normal. The second preset time is greater than the first preset time.

[0020] Step 4: The vehicle control unit sets the vehicle lock mode according to the vehicle lock instruction and sets the vehicle normal mode according to the normal instruction.

[0021] The vehicle control unit is connected to the vehicle network terminal and is used to set the lock mode according to the lock command and the normal mode according to the normal command. After the VCU sets the lock mode, it prohibits starting in the next driving cycle, or limits the speed after the next start (the speed limit can be set to 5Km / h to meet emergency needs such as moving the car), avoiding safety risks in the current unknown vehicle condition.

[0022] The present invention provides a remote car locking system and method, and the technical solution includes a TSP background, a mobile phone Bluetooth digital key, a vehicle TBOX, a central control HMI (human-machine interface), and a VCU (vehicle controller). The Bluetooth control module is integrated in the vehicle TBOX. The TBOX has both 4G / 5G network communication and local Bluetooth communication, and is connected to the TSP background and the mobile phone Bluetooth digital key respectively. Only when there are problems with both communication links will the car locking mode be triggered. The Bluetooth link of the TBOX reuses the Bluetooth digital key system, and no separate hardware device is added, and it also has a sufficient network security level. The present application provides a system solution that does not add an additional detection system, but directly combines the original car's existing Bluetooth digital key system to determine whether to lock the car. The car can continue to be locked for the network loss of the artificially wrapped shielding layer, and the car locking restriction can be lifted for the non-artificial network loss, reducing user complaints and property safety risks caused by the wrongly locked car.

[0023] Embodiment 2: The present application provides a system and method for remotely locking a vehicle. Figure 1 As shown in FIG2 , the system includes an in-vehicle network terminal, a remote service background system, a mobile phone Bluetooth digital key, a vehicle control unit and a central control human-machine interface. As shown in FIG2 , the method steps are as follows.

[0024] Step 1: The vehicle network terminal exchanges information with the remote service background system through the network and exchanges information with the mobile phone Bluetooth digital key through Bluetooth; Step 2: Determine whether the network and Bluetooth are normal based on the information interaction results; Step 3: When the network is continuously lost for more than the first preset time and the Bluetooth cannot communicate normally, a lock command is sent to the vehicle control unit, and a second status prompt command is sent to the central control human-machine interface; when the network communication is normal, or the network is continuously lost for less than the first preset time, a normal command is sent to the vehicle control unit; when the network is continuously lost for more than the first preset time and the Bluetooth communicates normally, a normal command is sent to the vehicle control unit, and a first status prompt command is sent to the central control human-machine interface; when the network is continuously lost for more than the second preset time, a lock command is sent to the vehicle control unit, and a third status prompt command is sent to the central control human-machine interface, and when the network communicates normally, go to step 2; like Figure 3As shown, the technical solution provided by the present invention may have four states: State 0, TBOX's 4G / 5G network communication is normal or the continuous duration of communication loss is less than the first preset time, TBOX is set to state 0 (network normal) and sends normal to VCU. At this time, the central control HMI has no prompt, and VCU is set to normal mode.

[0025] State 1: After TBOX experiences 4G / 5G network communication loss and the loss continues for more than the first preset time, if the vehicle's mobile phone digital key and the Bluetooth key control module of TBOX have completed authentication and are in a connected state, TBOX sets state 1 (network abnormality, Bluetooth normal) and sends the first state prompt command to the central control HMI. The central control HMI prompts the user "Please leave the area with poor network as soon as possible or perform network maintenance and inspection. The vehicle will be restricted after X time"; at the same time, TBOX also sends normal commands to the vehicle controller VCU, and the VCU sets to normal mode.

[0026] State 2: After TBOX loses 4G / 5G network communication and the loss continues for more than the first preset time, if TBOX is not connected to the Bluetooth key at this time, TBOX sets state 2 (network abnormality, Bluetooth abnormality) and sends the second state prompt command to the central control HMI. The central control HMI prompts the user that "TBOX network is abnormal, the vehicle enters the lock mode, and the next start is restricted. Please hold the digital key of this vehicle and connect to the vehicle to temporarily release the lock mode"; at the same time, the lock command is sent to the VCU, and the VCU sets the lock mode.

[0027] State 3: When TBOX loses 4G / 5G network communication and the loss lasts for more than the first preset time (in state 1 or state 2), it determines whether the second preset time has been exceeded. If the network communication is still not restored after the second preset time has expired, TBOX will set state 3 (network abnormality timeout) and send the third state prompt command to the central control HMI. The central control HMI prompts the user that "TBOX network is abnormal, the vehicle enters the lock mode, and the next start is restricted". At the same time, it sends a lock command to the vehicle controller VCU, and the VCU sets the lock mode. Figure 4 As shown, after the TBOX enters state 3, it cannot jump to state 1 or state 2 and must go through state 0. After the second preset time is reset, it switches from state 0 to state 1 or state 2.

[0028] Step 4: The vehicle control unit sets the vehicle lock mode according to the vehicle lock instruction and sets the vehicle normal mode according to the normal instruction.

[0029] Step 5: According to the first status prompt, the central control human-machine interface prompts the driver to leave the current area and check the network, and the vehicle will be restricted after T1 time; according to the second status prompt, the driver is prompted that the vehicle enters the locked mode and please use the mobile phone Bluetooth digital key to release it; according to the third status prompt, the driver is prompted that the on-board network terminal is abnormal, the vehicle enters the locked mode, and the next start is restricted.

[0030] The present invention provides a remote car locking system and method, and the technical solution includes a TSP background, a mobile phone Bluetooth digital key, a vehicle TBOX, a central control HMI (human-machine interface), and a VCU (vehicle controller). The Bluetooth control module is integrated in the vehicle TBOX. The TBOX has both 4G / 5G network communication and local Bluetooth communication, and is connected to the TSP background and the mobile phone Bluetooth digital key respectively. Only when there are problems with both communication links will the car locking mode be triggered. The Bluetooth link of the TBOX reuses the Bluetooth digital key system, and no separate hardware device is added, and it also has a sufficient network security level. The present application provides a system solution that does not add an additional detection system, but directly combines the original car's existing Bluetooth digital key system to determine whether to lock the car. The car can continue to be locked for the network loss of the artificially wrapped shielding layer, and the car locking restriction can be lifted for the non-artificial network loss, reducing user complaints and property safety risks caused by the wrongly locked car.

[0031] In summary, an embodiment of the present invention provides a remote vehicle locking system and method. This technical solution uses the digital key connection verification function of the vehicle itself to double confirm whether the TBOX is blocked, thereby reducing customer complaints and safety risks caused by accidentally locking the vehicle.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
