DETAILED DESCRIPTION

(10) Reference will now be made in detail to the presently preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings. Throughout the following detailed description, the same reference numerals refer to the same elements in all figures.

(11) Referring to FIG. 1, a view of the vehicle tracking device installed on a vehicle is shown.

(12) The motion detection and notification device 1 is shown installed on a vehicle 2, here a motorcycle.

(13) The vehicle 2 includes an engine 4 that creates mechanical energy, a portion of which charges the vehicle battery 6 (hidden beneath the seat of the vehicle 2). The vehicle battery in turn sends power to the motion detection and notification device 1.

(14) An ignition 8 controls the on/off state of the vehicle 2, and is an optional additional input to the motion detection and notification device 1.

(15) Referring to FIG. 2, a close-up view of the vehicle tracking device installed on a vehicle is shown.

(16) The components of the motion detection and notification device 1 are largely surrounded by a protective case 10.

(17) Visible through the case 10 are the cell signal light 12 and GNSS is (Global Navigation Satellite System) signal light 14. These lights 12/14 are used during the installation process to indicate a successful connection to their respective data sources.

(18) Power wire 16 and ground wire 18 connect the motion detection and notification device 1 to the vehicle battery 6 (see FIG. 1).

(19) Referring to FIG. 3, a schematic view of the distance tracking feature of the vehicle tracking system is shown.

(20) During operation, the motion detection and notification device 1 mounted on vehicle 2 tracks the position of the portable device 100 with respect to the vehicle 2.

(21) When the portable device 100 is too far from the vehicle 2, defined as outside the activation distance 110, the motion detection and notification device 1 switches to an armed state.

(22) If the portable device 100 returns to a position within the activation distance 110, the motion detection and notification device 1 switches to a disarmed state.

(23) Note that the above assumes that the portable device 100 is an authorized device. An unarmed device that moves within the activation distance 110 will not cause the motion detection and notification device 1 to switch to a disarmed state.

(24) The distance of the portable device 100 from the vehicle 2 is determined using one of multiple methods: signal strength measurement, differential GNSS position of the motion detection and notification device 1 and portable device 100, Bluetooth proximity detection, Bluetooth real-time locating systems (RTLS), Bluetooth indoor positioning systems (IPS), or similar methodologies.

(25) Referring to FIG. 4, an overview of the system components and their methodology of operation is shown.

(26) The motion detection and notification device 1 includes a case 10 that surrounds one or more circuit boards 20.

(27) Mounted on the circuit board(s) 20 is a processor 24, connected to an accelerometer 22, cellular modem 26 with cellular antenna 28, Bluetooth module 30 with Bluetooth antenna 32, and GNSS receiver 34 with GNSS antenna 36.

(28) The antennas 28/32/36 are mounted on the circuit board 20, exist as separate components within the case 10, or protrude outside the case 10 if needed for superior signal acquisition.

(29) The processor 24 and other components are powered via a voltage regulator 38. The voltage regulator is preferably supplied by both the vehicle battery 6 and a backup battery 40.

(30) The cellular modem 26 communicates with a cellular tower 42 to send and receive data. Data is then transmitted over the Internet 52 to the cloud 50, ultimately being stored in the SMC database 56, accessible from the Secure Monitoring Center 54 via the Internet 52.

(31) The Bluetooth module communicates with one or more portable devices 100.

(32) The GNSS receiver receives signals from positioning satellites 44, such as those that are part of the GPS, GLONASS, and Galileo systems.

(33) Referring to FIG. 5, an overview of how data flows within the system is shown.

(34) The cellular modem 26 communicates with a cellular tower 42 to send is and receive data. Data is then transmitted over the Internet 52 to the cloud 50, where the data is accessible by the SMC (Secure Monitoring Center) 54.

(35) Referring to FIG. 6, a flowchart of system operation for arming is shown.

(36) The system first determines whether the vehicle 2 (See FIG. 1) is parked 200. This is done by monitoring the status of the ignition 8 (See FIG. 1) or waiting a pre-determined amount of time where position remains unchanged and the accelerator records no movement, or movement only associated with a user positioning the vehicle 2.

(37) If the vehicle 2 is not parked, the system waits 202.

(38) If the vehicle 2 is parked, the system next monitors the position of the portable device 100 (See FIG. 3). If the portable device 100 has not exceeded the activation distance 110 (See FIG. 3), then the system waits 206.

(39) If the portable device 100 has exceeded the activation distance 204, the system state is changed to Armed 208. The subroutine of monitoring for motion is shown in FIG. 7, reference 209.

(40) With the system in an Armed state, it continues to monitor 210 for return of the portable device 100. If no portable device 100 is in range, the system waits 212, then checks again.

(41) If a portable device 100 is in range, the system compares the identification (ID) of the portable device 100 to its database of authorized IDs 214.

(42) If the ID is not authorized, the system records the ID 216 in case the information becomes useful as part of recovery. The recorded ID is sent to the SMC 218 for recordation in the database. The system then waits 220.

(43) If the ID is authorized as a known ID, the system state is changed to Disarmed 222.

(44) Referring to FIG. 7, a flowchart of system operation for position tracking and reporting is shown.

(45) The theft detection subroutine first checks for a system state of Armed 230. If the system is not Armed, it waits 232.

(46) If the system state is Armed, the system watches for any data from the accelerometer reporting motion 234. If no motion is reported, the system waits 236, then checks again.

(47) The system simultaneously watches for the GNSS receiver to report any change in position 238. If no position change is detected, the system waits 240.

(48) When the system state is Armed, most commonly the vehicle will be in a fixed position, waiting for the user to return. Thus, the accelerometer and GNSS receiver will generally report no motion, and the system will continue to wait.

(49) But, if the accelerometer or GNSS receiver report motion, the vehicle is potentially being moved by a malicious third-party. This triggers the system to begin motion tracking and reporting.

(50) The system first sends an alert message to the portable device, using either Bluetooth or data via the cellular modem and Internet, and send an alert message to the SMC (Secure Monitoring Center) 242.

(51) The system stores the alerts in internal memory 244.

(52) The system continues to read both accelerator and GNSS data 246, and to store the data internally 248.

(53) If a cellular connection exists 250, the accelerometer data and GNSS data are sent to the SMC 252.

(54) The system then confirms that it is still armed 252. If yes, the monitor/store/send steps 246/248/250/252 are repeated. If not, the system waits 256, and returns to again check whether armed 230, repeating its waiting until again armed.

(55) Referring to FIG. 8, a flowchart of system operation during installation is shown.

(56) The device is purchased 260 for installation. The device is registered in the SMC database 262, connecting the specific device to its associated vehicle.

(57) During registration, or after registration, the user or installer authorizes one or more portable devices 264. The portable device information is saved in the SMC Database in association with the vehicle.

(58) With the device initialized, installation is started 266.

(59) First, power is connected 268. With power connected, the GNSS receiver searches for a signal. When received, the device lights the GNSS indicator light 270. This light indicates to the installer that position data is being received.

(60) With power connected, the cellular model searches for a signal. When received, the device lights the cellular data indicator light 272. This light indicates to the installer that a cellular data connection is confirmed.

(61) The device then pauses the requirement for an authorized portable device 274. This authorization is preferably paused for thirty minutes, but other amounts of time are anticipated. Pausing the requirement for an authorized portable device allows the installer to complete installation without triggering the device to be armed.

(62) After thirty minutes, or the desired time, has elapsed since confirmed connection of the GNSS receiver and cellular modem, the indicator lights are disabled 276.

(63) The device then sends a message to the to confirm setup is complete 278.

(64) The system then begins normal operation 280.

(65) Equivalent elements can be substituted for the ones set forth above such that they perform in substantially the same manner in substantially the same way for achieving substantially the same result.

(66) It is believed that the system and method as described and many of its attendant advantages will be understood by the foregoing description. It is also believed that it will be apparent that various changes may be made in the form, construction, and arrangement of the components thereof without departing from the scope and spirit of the invention or without sacrificing all of its material advantages. The form herein before described being merely exemplary and explanatory embodiment thereof. It is the intention of the following claims to encompass and include such changes.
