Background
Vehicle theft has been a concern. The anti-theft technology can be divided into two aspects, one is to prevent theft, such as the functions of vehicle door lock and engine theft prevention which are continuously upgraded, the other is to locate and track after the theft occurs, and the GPS tracker and other commodities are sold at present. With the development of automobile electromotion and networking, the T-BOX also has a certain security function, and the automobile and component industries also continuously research and develop the tracking and positioning functions of automobile theft prevention and stolen automobile.
The invention patent with Chinese patent application publication No. CN 108340880A discloses a global stolen vehicle tracking scheme, which comprises a vehicle remote information processing control unit, a mobile device, a vehicle theft system and a vehicle information server, wherein a user proposes an application after discovering that a vehicle is stolen, and the vehicle information server identifies through a vehicle network identifier after receiving the application and carries out positioning and tracking through a specific communication network. The existing positioning and tracking scheme has the following defects:
1. the prior art is triggered by applying after a user finds that a vehicle is stolen, and belongs to subjective judgment that the vehicle is stolen, namely, the time from the vehicle is stolen to the time when the vehicle is found to be stolen is uncontrollable, and the vehicle can be transferred, shielded and changed in the time, so that the positioning and tracking are invalid.
2. In the prior art, in order to seek for the maximization of economic benefit, vehicles are not distinguished and responded, and the specialty is weak. Actually, passenger cars and commercial vehicles, fuel oil vehicles and electric vehicles are different in vehicle characteristics, use purposes and driving areas, theft may occur in cities, underground garages, remote mountain areas, road conditions, city monitoring and other public facility matching conditions, and tracking difficulty is different.
3. The prior art location and tracking relies heavily on the service provider network, and once the network is uncovered or maliciously shielded, the vehicle will fail to locate and the tracking will fail.
4. The prior art excessively depends on the wireless transceiver at the vehicle end, but is limited in the protection degree of the wireless transceiver, and once the wireless transceiver is maliciously disassembled, the vehicle cannot be positioned.

when the vehicle is normal, the vehicle-mounted T-BOX 4 periodically communicates with the fleet management background 10 through the GPRS network 9 to send out information such as positioning, vehicle speed and the like, and at the moment, the vehicle-mounted T-BOX 4 sends out two paths of periodic signals T-BOX working signals and T-BOX communication signals to the anti-theft controller 5.
The anti-theft controller 5 firstly judges the T-BOX working signal, further judges the T-BOX communication signal when the T-BOX working signal is normal, and outputs safety information to the VECU when the T-BOX communication signal is normal, the vehicle is not limited, and the vehicle-mounted T-BOX continuously sends out periodic signals.
When the T-BOX working signal is abnormal, the communication judgment module 52 in the anti-theft controller 5 is activated to receive the GPS signal from the GPS module and the GPRS signal from the GPRS module, and outputs a safety signal to the control module 56 after judging that the GPS signal and the GPRS signal are normal, the safety judgment module 58 in the control module 56 outputs alarm information and positioning information to the fleet management background 10, the fleet management background 10 notifies the user 11 of a prompt, and the safety judgment module 58 outputs safety information to the VECU, and the vehicle is not limited.
If the communication judgment module 52 judges that the GPS signal and the GPRS signal are abnormal, the timing control module 57 starts to perform abnormal state timing, if the abnormal state is less than or equal to 5min, and the vehicle speed judgment module 51 outputs the vehicle speed signal, the timing control module 57 outputs the safety signal safety judgment module 58, the safety judgment module 58 outputs alarm information and positioning information to the fleet management background 10, the fleet management background 10 informs the user 11 of prompting, and meanwhile, the safety judgment module 58 outputs safety information to the VECU, and the vehicle is not limited. If the abnormal state is more than 5min, the timing control module 57 sends an authentication signal to the ownership authentication module 55, the ownership authentication module 55 is activated, timing and counting are started, and when the touch screen signal fed back by the touch screen 7 is the same as the preset value within 3 minutes and within 5 times, the ownership authentication module 55 judges and outputs safety information to the VECU, and the vehicle is not limited; otherwise, the authority authentication module 55 judges and outputs a fault signal to the safety judgment module, the safety judgment module 58 outputs a theft signal to the VECU, and the VECU limits the torque and extinguishes the fire within 2 minutes.
When the T-BOX working signal is normal but the T-BOS communication signal is abnormal, the timing control module 57 judges that the abnormal state is less than or equal to 5min, safety information is output to the VECU, and the vehicle is not limited; if the abnormal state is more than 5min, the timing control module 57 sends an authentication signal to the ownership authentication module 55, the ownership authentication module 55 is activated, timing and counting are started, and when the touch screen signal fed back by the touch screen 7 is the same as the preset value within 3 minutes and within 5 times, the ownership authentication module 55 judges and outputs safety information to the VECU, and the vehicle is not limited; otherwise, the authority authentication module 55 judges and outputs a fault signal to the safety judgment module 58, the safety judgment module 58 outputs a theft signal to the VECU, and the VECU can limit the torque and extinguish the fire within 2 minutes.
