Auto-immobilization based on tampering or jamming detection
Methods, systems, and computer programs are presented for immobilizing a vehicle based on the detection of threats, such as tampering or jamming. The method includes configuring a vehicle for tamper and jamming detection, installing a communication device and an engine immobilizer in the vehicle, and providing a user interface for configuring the communication device to activate the engine immobilizer. The method further includes parallel paths for tampering detection, which immobilizes the vehicle and notifies the server upon detection, and for jamming detection, which similarly immobilizes the vehicle and notifies the server, including the vehicle's GPS position. Optionally, image information from the vehicle may be included in the notification or to trigger immobilization upon detecting multiple occupants, indicating a potential carjacking. This solution enables fleet managers to react to thefts and maximize vehicle recovery rates quickly.
1. A computer-implemented method comprising:
detecting, by monitoring device at a vehicle, a jamming condition that indicates interference with satellite positioning signals;
after a predefined wait time in the jamming condition, disabling an accelerator in the vehicle;
after disabling the accelerator and detecting that the vehicle has stopped, disabling an ignition of the vehicle;
receiving, via a radiofrequency communication medium, a command to remobilize the vehicle; and
enabling, in response to the command to remobilize the vehicle, the accelerator and the ignition in the vehicle.
2. The method as recited in claim 1 , further comprising:
detecting, by the monitoring device at the vehicle, tampering in the vehicle based on a removal of a dashboard cover of a location where the monitoring device is installed; and
in response to detecting the tampering, disabling the accelerator and the ignition of the vehicle.

sending a request, from the monitoring device to an engine immobilizer, to activate a relay of the engine immobilizer that disables the accelerator of the vehicle.
6. The method as recited in claim 1 , wherein disabling the ignition in the vehicle further comprises:
sending a request, from the monitoring device to an engine immobilizer, to activate a relay of the engine immobilizer that disables the ignition in the vehicle.
7. The method as recited in claim 1 , further comprising:
providing a user interface (UI) with options to configure immobilization parameters for the vehicle, the options comprising an immobilization speed threshold, automatic vehicle immobilization enabled or disabled, and operation of relays on an engine immobilizer in the vehicle.
8. The method as recited in claim 7 , further comprising:
in response to receiving selections of the immobilization parameters in the UI, sending information on the immobilization parameters to the monitoring device at the vehicle.
9. The method as recited in claim 1 , further comprising:
sending, from the monitoring device to a server, a notification that the accelerator has been disabled.
10. The method as recited in claim 9 , wherein the notification includes video data of a cabin in the vehicle and the road in front of the vehicle.
11. A system comprising:
a memory comprising instructions; and
one or more computer processors, wherein the instructions, when executed by the one or more computer processors, cause the system to perform operations comprising:
detecting, by monitoring device at a vehicle, a jamming condition that indicates interference with satellite positioning signals;
after a predefined wait time in the jamming condition, disabling an accelerator in the vehicle;
after disabling the accelerator and detecting that the vehicle has stopped, disabling an ignition of the vehicle;
receiving, via a radiofrequency communication medium, a command to remobilize the vehicle; and
enabling, in response to the command to remobilize the vehicle, the accelerator and the ignition in the vehicle.
12. The system as recited in claim 11 , wherein the instructions further cause the one or more computer processors to perform operations comprising:
detecting, by the monitoring device at the vehicle, tampering in the vehicle based on a removal of a dashboard cover of a location where the monitoring device is installed; and
in response to detecting the tampering, disabling the accelerator and the ignition of the vehicle.
13. The system as recited in claim 12 , wherein the tampering is detected by an engine immobilizer with a connection to the dashboard cover.
14. The system as recited in claim 11 , wherein detecting the jamming condition further comprises:
obtaining a position quality parameter and an analog measurement from a GPS module;
calculating a difference between the analog measurement and a reference analog measurement obtained by the GPS module; and
determining the jamming condition based on the difference and the position quality parameter.
15. The system as recited in claim 11 , wherein disabling the accelerator further comprises:
sending a request, from the monitoring device to an engine immobilizer, to activate a relay of the engine immobilizer that disables the accelerator of the vehicle.
16. A non-transitory machine-readable storage medium including instructions that, when executed by a machine, cause the machine to perform operations comprising:
detecting, by monitoring device at a vehicle, a jamming condition that indicates interference with satellite positioning signals;
after a predefined wait time in the jamming condition, disabling an accelerator in the vehicle;
after disabling the accelerator and detecting that the vehicle has stopped, disabling an ignition of the vehicle;
receiving, via a radiofrequency communication medium, a command to remobilize the vehicle; and
enabling, in response to the command to remobilize the vehicle, the accelerator and the ignition in the vehicle.
17. The non-transitory machine-readable storage medium as recited in claim 16 , wherein the machine further performs operations comprising:
detecting, by the monitoring device at the vehicle, tampering in the vehicle based on a removal of a dashboard cover of a location where the monitoring device is installed; and
in response to detecting the tampering, disabling the accelerator and the ignition of the vehicle.
18. The non-transitory machine-readable storage medium as recited in claim 17 , wherein the tampering is detected by an engine immobilizer with a connection to the dashboard cover.
19. The non-transitory machine-readable storage medium as recited in claim 16 , wherein detecting the jamming condition further comprises:
obtaining a position quality parameter and an analog measurement from a GPS module;
calculating a difference between the analog measurement and a reference analog measurement obtained by the GPS module; and
