Field of the invention
[0001] The present disclosure relates to a system and a method to track a vehicle.

Background of the invention

[0002] Currently vehicle coming with in-built GPS system which is used to track location of vehicle from anywhere. However, in the present systems, vehicle owners come to know of the position of the vehicle only when the vehicle battery is present. Vehicle owners come to know of a possible theft only when they check vehicle availability using mobile or other electronic devices. Further, Vehicle location may not be accessible through mobile when vehicle battery is removed or stolen.
[0003] The prior art VN10036678 B discloses an anti-theft system for rental or loaned cars, including: one or more master devices (20) equipped with GPS positioning, the internal control network communication unit of the vehicle. vehicle CAN (Control Area Network) (27) and vehicle speed signal receiver circuit (24) master device (20) is now placed on the anti-theft lever, master device (20) also has the usual features Like other navigation devices, it uses the GPS navigation system to determine the position as well.

[0004] Currently, Wake-up ECU (electronic control unit)based anti-theft systems are not available in vehicles. Wake-up ECU monitor input conditions (such as motion detection or other triggers) and when these conditions are met, it can wake up (activate) other electronic system. This allows other electronic systems to remain in an inactive state or a sleep state until triggered by wake-up ECU.

An embodiment of the invention is described with reference to the following accompanying drawings:
[0006] Figure 1 depicts a system to track a vehicle.
[0007] Figure 2 depicts a flowchart for a method to track a vehicle.
Detailed description of the drawings:

[0008] The present disclosure provides a system and a method to track a vehicle. In the present disclosure Vehicle theft is identified using synchronization of vehicle GPS location and user’s Mobile GPS location. The owner will be notified even if the vehicle battery is removed.
[0009] When vehicle battery is removed, GPS in the system will be activated (wake up) by a wake-up controller followed by an alert/notification to user. The wake-up controller will be in communication with at least one vehicle sensor capable of detecting an activity corresponding to a theft or invasion. The GPS will be activated upon reception of any signal from the at least one sensor by the wake up controller. An auxiliary battery may be used to power the entire system so that GPS will wakeup during any movement in vehicle even when the vehicle ignition is off (or vehicle is parked).
[0010] The present invention will now be described by way of example, with reference to accompanying drawings. Throughout all the figures, same or corresponding elements may generally be indicated by same reference numerals. These depicted embodiments are to be understood as illustrative of the invention and not as limiting in any way. It should also be understood that the figures are not necessarily to scale and that the embodiments are sometimes illustrated by graphic symbols, phantom lines, diagrammatic representations and fragmentary views. In predetermined instances, details which are not necessary for an understanding of the present invention, or which render other details difficult to perceive may have been omitted.
[0011] Referring to Figure 1, the same depicts a system (10) to track a vehicle (9). The system comprises a wake-up controller (1). The wake-up controller may be a wake up ECU (engine control unit). Wake-up ECU monitors input conditions (such as motion detection or other triggers) and when these conditions are met, it can wake up (activate) other electronic systems. The wake-up controller (1) may comprise a main unit as a microcomputer which further comprises a CPU, a memory with integrated control logic, the circuitry including the wake up circuitry and the power management circuitry. It may further comprise of transistors, switches or relays to turn the power supply ON or OFF and other protection components such as diodes and fuses for protection against voltage spikes.
[0012] The controller (1) (wake up ECU) may further comprise communication interfaces such as UART, SPI, I2C or CAN. The controller may be linked to other electronic components and other ECUs of the vehicle through a network bus capable of sending signals across the network to all ECUs it connects. The controller may further comprise a transmitter and a transceiver capable of sending and receiving signals. Said wake up controller (1) is further in communication with a global positioning system (GPS) (2) by means of an in vehicle communication means such as the CAN BUS.
[0013] Said wake up controller (1) is in communication with at least one sensor(3). Said wake up controller (2) is configured to receive at least one signal (3) from the at least one sensor (3) in communication with the wake up controller. The signal may be indicative of any parameter depending upon the type of sensor.
[0014] In an example the at least one sensor may be a sensor capable to detect a parameter indicative of theft. In an example the at least one sensor may be a wheel sensor, yaw rate sensor, oxygen sensor, steering position sensor, RFID Transreciever. In an example, if the vehicle is a two wheeler, it may be a pressure sensor in handlebar, a sensor on a side stand or a tilt sensor. It is to be understood that the sensors listed above are for mere understanding of a person ordinarily skilled in the art. These are not to be construed as limiting the scope of the disclosure as the sensor may be any sensor capable of detecting movement of the vehicle, theft of the vehicle or any of its component or a human inside the vehicle. The at least one sensor sends an activation signal to the controller. The activation signal will be a Wake-Up Signal (WUS). The WUS is a communication mechanism used in communication systems to activate or "wake up" a device from a low-power or sleep state. In an example, if the at least one sensor is a wheel speed sensor, the wheel speed sensor upon detection of a threshold vehicle speed will send an activation signal to the wake up controller which in turn may activate the GPS system based on a threshold value of the activation signal received by the wake up controller from the wheel speed sensor. Said threshold value may be any physical value such as a threshold voltage, threshold current, etc. In an example, the activation of the wake up controller may happen only upon satisfaction of certain conditions such as detection of movement when ignition(4) is OFF.

[0015] Said wake-up controller is configured to activate the GPS (2). The GPS is activated by the wake up controller. The same may be achieved by an activation circuit. A person skilled in the art will appreciate that the activation circuit may comprise of microcontrollers or dedicated logic control to generate signals based on inputs to activate a desired functionality. It may further comprise of transistors, switches or relays to turn the power supply ON or OFF and other protection components such as diodes and fuses for protection against voltage spikes.
[0016] Upon activation the GPS (2), the GPS sends the positional information (5) of the vehicle to a user device through an interface(6). The interface may be a gateway not limited to LTE , Wifi, Bluetooth (non-exhaustive list including all wireless communication technologies).
[0017] Further the type of warning/alert to the user can be chosen based on user need. The system may also be linked to signaling system of the vehicle to give an audio/visual warning . The alert may also be given to the user based on the distance of the user from the vehicle, speed of the vehicle, ignition ON/OFF state.

[0018] The entire system (10) will run even without the vehicular battery as the entire system can be powered by an auxiliary battery (8). The wake-up ECUs themselves are energy saving making the entire system (10) an energy efficient theft detection system. The system may be hidden inside the vehicle.

[0019] Referring to figure 2, the same depicts a flowchart for a method to track a vehicle implemented by the system (10) as described above. It is to be understood that all components necessary to implement the method (100) have been described in Figure 1 above. The method (100) comprises the first step (101) of receiving, by the wake up controller, at least one activation signal from at least one sensor of the vehicle, followed by the second step (102) of activating the GPS , by the wake up controller. This is followed by the step (103) of sending a positional information of the vehicle, by the GPS, to a user’s device through an interface. Said system by an auxiliary battery. According to an aspect of the embodiment, the present disclosure proposed a method of tracking the vehicle in an event of a missing battery of the vehicle.
[0020] In an example, if the at least one sensor is a wheel speed sensor, the wheel speed sensor upon detection of a threshold vehicle speed will send an activation signal to the wake up controller which in turn may activate the GPS system based on a threshold value of the activation signal received by the wake up controller from the wheel speed sensor. Said threshold value may be any physical value such as a threshold voltage, threshold current, etc. In an example, the activation of the wake up controller may happen only upon satisfaction of certain conditions such as detection of movement when ignition is OFF. Said wake-up controller upon activation activates. The same may be achieved by an activation circuit. Upon activation the GPS, the GPS sends the positional information of the vehicle to the user through an interface. The interface may be a gateway not limited to LTE , Wifi, Bluetooth (non-exhaustive list including all wireless communication technologies).
[0021] In the present invention vehicle theft is identified using synchronization of vehicle GPS location and user’s Mobile GPS location. The owner will be notified even if the vehicle battery is removed.
