[0024] Embodiment
[0025] As Figure 1 shown, the present application provides an automotive anti-theft control unit, and the automotive anti-theft control unit includes a VIN reading module.
[0026] The VIN reading module is connected to a key identification and authentication unit through a CAN bus. The key identification and authentication unit is also connected to a central control unit through the CAN bus, and the central control unit is integrated into the vehicle control system. A rolling code encryption unit is provided at the series connection of the central control unit and the key identification and authentication unit to achieve multiple communication encryption protections between the key and the vehicle.

The central control unit is connected to a sensor unit through the CAN bus.
[0027] Further, in a preferred embodiment of the present utility model, a door control sensor, a window sensor, a vibration sensor, and an inclination sensor are integrated inside the sensor unit.
[0028] Further, in a preferred embodiment of the present utility model, the sensor unit is connected to an alarm module, and the alarm module is used to issue an alarm signal in response to abnormal behaviors of the vehicle.
[0029] Further, in a preferred embodiment of the present utility model, the alarm module is connected to a remote communication module, and the remote communication module is used to feedback an alarm prompt to the vehicle owner user.
[0030] Further, in a preferred embodiment of the present utility model, the central control unit is connected to an engine control unit through the CAN bus to control the release and locking of engine startup.
[0031] Further, in a preferred embodiment of the present utility model, the engine control unit is connected to an Internet of Things module.
[0032] Furthermore, in a preferred embodiment of the utility model, the Internet of Things module is connected to an anti-theft monitoring module via a CAN bus, and the anti-theft monitoring module is used to monitor the anti-theft behavior of the vehicle in real time.
[0033] Furthermore, in a preferred embodiment of the present invention, the anti-theft monitoring module is integrated with a vehicle tailgating sensing module, which can sense the potential tailgating risk of the vehicle.
[0034] Furthermore, in a preferred embodiment of the present invention, the vehicle tailgating sensing module is synchronously connected to the Internet of Things module, and the vehicle tailgating sensing module and the anti-theft monitoring module are connected to the remote communication module via a CAN bus.
[0035] Furthermore, in a preferred embodiment of the present invention, the vehicle tailgating sensing module and the anti-theft monitoring module are synchronously connected to the remote communication module to realize the feedback of vehicle tailgating information and anti-theft monitoring data to the mobile terminal of the vehicle owner.
[0036] The working process of the utility model is as follows:
[0037] First, the control power module powers on the central control module, and the power adapter delivers current to synchronously activate, check and initialize the status of the sensor unit, VIN reading module and vehicle networking module. The VIN reading module waits to read the unique VIN identification information of the vehicle key, and then the system starts to execute key verification tasks, engine control tasks, sensor anti-theft alarm tasks and vehicle networking monitoring feedback tasks.
[0038] The key verification task mainly uses RFID radio frequency identification technology to perform identification and verification on the unique VIN key information in the vehicle key. At this time, when the key chip in the vehicle key is close to the VIN reading module, the VIN reading module will read and identify the VIN identification information in the key chip. The key identification and authentication unit can detect the encrypted information in the authentication VIN identification information, and the rolling code encryption unit uses the rolling code encryption technology to perform rolling decoding on the encrypted information. If the rolling code data decoded from the encrypted information of the key matches the preset rolling code data stored in the system, it means that the vehicle key belongs to this vehicle and is determined to be authenticated successfully. At this time, the central control unit generates an authentication success instruction; if the decoded rolling code data matches the preset rolling code data stored in the system, it means that the vehicle key does not belong to this vehicle and is determined to be authenticated failed. The central control unit generates an authentication failure instruction. Finally, the central control unit transmits the authentication success instruction or the authentication failure instruction to the engine control module.
[0039] The engine control task is responsible for performing control analysis, anti-theft unlocking control, and anti-theft locking control on the engine according to the authentication instructions output in the key verification task. When the engine control unit receives an authentication success instruction, the engine control unit will unlock the engine based on the authentication success instruction and allow the user to start the engine to drive the vehicle to start. If the engine control unit receives an authentication failure instruction, the engine control unit will immediately cut off the engine startup circuit to prevent the engine from running. At the same time, the engine control unit can evaluate the anti-theft risk level based on the authentication failure instruction and set the locking time according to the anti-theft risk level to temporarily lock the vehicle for a period of time to prevent repeated cracking attempts.
[0040] The sensor anti-theft alarm task mainly controls the alarm unit to respond to abnormal illegal intrusion behaviors based on the sensing data detected by the sensing unit. The door control sensor is responsible for collecting the opening state data of each door when the vehicle is not allowed to be unlocked. The window sensor globally detects the abnormal opening and breaking state data of each glass on the vehicle door. The vibration sensor detects abnormal vibrations or movements of the vehicle on the vehicle. The tilt sensor regularly collects the state data of abnormal angle tilts of the vehicle, such as when the vehicle is tried to be towed away or lifted forcibly, etc. When any one of the above door control sensors, window sensors, vibration sensors, or tilt sensors detects abnormal activity behaviors or intrusion behaviors of the vehicle, the alarm module will be triggered to send an alarm signal, and the alarm signal includes a horn sound and headlight flashing to achieve a fast anti-theft alarm effect.
[0041] The vehicle networking monitoring feedback task mainly monitors and timely feedbacks the anti-theft information of the vehicle after starting and after the vehicle is locked through vehicle networking technology. When the vehicle engine starts or the vehicle is locked, the vehicle networking module will be self-activated at this time. The vehicle networking module will then mobilize the anti-theft monitoring module to control the on-vehicle camera to monitor its external driving state and internal operation scenarios in real time to obtain the real-time itinerary information and real-time vehicle operation information during the use of the vehicle engine, and transmit the real-time itinerary information and real-time vehicle operation information to the remote communication module, and the remote communication module will then feedback it to the user's mobile terminal so that the user can timely receive the current use state of the vehicle inside and outside through the mobile terminal. When the vehicle owner enters or leaves the vehicle, the vehicle following perception module will be synchronously activated to perceive the vehicle following state of the vehicle's tail. If the vehicle following perception module detects that the vehicle is being followed by other vehicles for a long time, the system will automatically lock the door or issue an alarm to notify the vehicle owner to be vigilant.
[0042] In summary, the VIN reading module and the key identification and authentication unit carried by an automotive anti-theft control unit in this solution can perform secure encryption verification on the use of the vehicle, and the rolling code encryption unit can use a rolling code encryption protocol with a certain degree of complexity to prevent hackers or relay attacks from stealing the vehicle, ensuring the uniqueness and security of the communication between the vehicle key and the vehicle, and improving the anti-theft coefficient. The various sensors integrated inside the sensor unit can continuously obtain the overall usage situation of the vehicle when it is in a stationary or active state, detect potential theft behaviors of the vehicle, thereby effectively preventing the risk of vehicle theft, reducing the risk index of vehicle theft when the vehicle is unattended, and enhancing the reliability of vehicle anti-theft. At the same time, it can avoid misdetection and missed detection of theft behaviors caused by certain non-human factors, ensuring the accuracy and rationality of vehicle anti-theft. Moreover, this method is also equipped with a vehicle networking module and a remote communication module, which can capture the face of the thief entering the vehicle or suspicious activities around the vehicle in real time, and at the same time can obtain whether there is a risk of suspicious vehicles trailing the current vehicle, and remotely notify the vehicle owner to raise vigilance, thereby reducing the risks of vehicle trailing and theft, improving the overall safety of the vehicle. Compared with traditional automotive anti-theft control units, it can greatly enhance the safety factor during the vehicle use process and in the remote unattended state, improve the anti-theft threat of existing known vehicle theft methods to vehicles, optimize the vehicle anti-theft performance, and eliminate the probability of vehicle theft.
[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the present technical solution, and they should all be covered within the scope of the claims of the present invention.
