The anti-theft system can include a vibration sensor coupled to the body of the vehicle and configured to detect vibration in the body due to an external impact, such as the forceful opening of the toolbox. The control unit coupled to the vibration sensor can receive a signal from the vibration sensor indicative of the external impact and in turn, can raise an alarm notifying the external impact.

Description

FIELD OF INVENTION

The present invention relates to an anti-theft system for vehicles, and more particularly, the present invention relates to a vibration-sensor-based anti-theft system for vehicles.

BACKGROUND

Thefts from vehicles have been an unsolved and serious problem for vehicle owners. A vehicle can have costly tools which if stolen results in huge economic loss to the owner and the trouble to procure new ones. For example, often trade tools get stolen from a locked toolbox installed in the rear of trucks. Incidents of such theft are more in the areas wherein vehicles are parked in the streets.

Thus, a desire is there for an anti-theft system that can trigger an alarm to notify a theft attempt from a vehicle.

In one aspect, disclosed is an anti-theft system for vehicles that are parked and engine turned off. The anti-theft system includes a vibration sensor that can detect any vibrations in the body of the vehicle. The vibration sensor can be operably coupled to a control unit which can receive a signal indicative of the intensity of vibrations from the vibration sensor, and based on a predefined rule, the control unit can trigger an alarm to notify about an attempt to steal from the vehicle.

In one aspect, the anti-theft system can be installed in the vehicle and connected to the vehicle's electrical system.

In one aspect, the alarm can be the vehicle's horn and light, wherein the control unit can trigger either or both the horn and lights of the vehicle to notify the people nearby about the attempt to steal from the vehicle.

In one aspect, the anti-theft system can provide for setting up a threshold for the intensity of vibrations to prevent any false alarm.

In one aspect, the control unit can include a network circuitry for connecting to an external network, wherein the control unit can send a notification to a user device through the network, the notification can be about the attempt to steal from the vehicle.

These and other objects and advantages of the embodiments herein and the summary will become readily apparent from the following detailed description taken in conjunction with the accompanying drawings.

The following detailed description includes the best currently contemplated mode or modes of carrying out exemplary embodiments of the invention. The description is not to be taken in a limiting sense but is made merely for the purpose of illustrating the general principles of the invention, since the scope of the invention will be best defined by the allowed claims of any resulting patent.

Referring to FIG. 1 which shows the disclosed anti-theft system 100 that can include vibration sensor 110. The vibration sensor 110 can be coupled to the body of the vehicle and can detect vibrations in the body of the vehicle. In one case, the vibrations in the body of the vehicle can be due to an external impact on the body of the vehicle which is parked and engine off. For example, the external impact can be the forceful opening of a toolbox in the vehicle. In trucks, a toolbox can be installed in the rear of the truck and can include tools. Forceful opening of the toolbox can result in vibrations that can be detected by the vibration sensor of the disclosed anti-theft system 100. The vibration sensor can sense vibrations in the wall of a parked vehicle, such as the vibrations caused by the forceful intrusion in the vehicle. The vibration sensors are known in the art. For example, a vibration sensor 110 can be provided that has a precision spring coil, through which a contact pin is installed in the center of the precision spring coil but without contact. Any vibration to this sensor will cause the spring coil to contact the center pin resulting in a signal. Another example of the vibration sensor can be a coil closed at both ends, with a ball bearing inside. Any vibration results in the ball bearing inside the coil reciprocate resulting in a signal. The intensity of the signal can be proportional to the intensity of vibrations detected by the vibration sensor 110.

The anti-theft system 100 can also include a control unit 120 operably coupled to the vibration sensor 110. The control unit 120 can receive a signal from the vibration sensor 110, wherein the signal includes the intensity of the signal. The control unit 120 can also be installed in the vehicle, such as the anti-theft system 100 can be installed in a new vehicle as well as retrofits in an existing vehicle. The anti-theft system 100 can be coupled to an electrical system 200 of a vehicle, such as the anti-theft system 100 can be powered by the electrical system 200 of the vehicle. Alternatively, the anti-theft system 100 can also be powered by a power supply separate from the vehicle's electrical system. Moreover, the anti-theft system 100 can be coupled to the horn 210 and lights 220 of a vehicle. The control unit 120 can trigger either or both the horn 210 and the lights 220 of the parked vehicle in a predetermined pattern as an alarm to gain the attention of the nearby people. for example, the light can be flashed and the horn at short durations, both patterns are indicative of an emergency.

The control unit 120 can receive a signal including the intensity of the signal, which is proportional to the intensity of vibrations picked from the vibration sensor. The control unit 120 can be configured with a threshold for the intensity of vibrations. The control unit 120 can compare if the signal received from the vibration sensor 110 has an intensity of vibration above the predefined threshold. In case, the received intensity of the vibrations is more than the predetermined threshold, the control unit can trigger the horn and/or light as an alarm to notify. The threshold may be such as to avoid any false alarm can be tweaked as and when required.

The control unit 120 can also have a network circuitry that allows the control unit to connect to an external network, such as Wi-Fi or cellular networks. The control unit 120 can also send notifications to a user device 310 through a network 300. The user device 310 can be an electronic device of the owner of the vehicle and can be a smartphone, tablet computer, smartwatch, and smart assistant, and like known consumer electronic devices. Such a step of notification on the user device can be helpful in case the owner is far from the vehicle out of the range of the horn.

While the foregoing written description of the invention enables one of ordinary skill to make and use what is considered presently to be the best mode thereof, those of ordinary skill will understand and appreciate the existence of variations, combinations, and equivalents of the specific embodiment, method, and examples herein. The invention should therefore not be limited by the above-described embodiment, method, and examples, but by all embodiments and methods within the scope and spirit of the invention as claimed.
