The present invention relates to detecting a puncture in a tire, and more specifically, this invention relates to detecting and locating a puncture in a tire and alerting a user to the specific location of the puncture.
Foreign objects may become embedded in a tire and cause damage to the tire and/or to other components of the vehicle. Drivers may not be immediately aware of a puncture in a tire due to sealants in the tire which prevent drastic changes in tire pressure, distractions on the road, the speed of travel, etc. Operating a vehicle with a tire puncture increases the likelihood of a blowout of the tire, resulting in a dangerous situation and/or a relatively more expensive repair.
An apparatus, according to one embodiment, includes a grid circuit having dimensions corresponding to an inner surface of a tire, a computational device coupled to the grid circuit, and a wireless communications device coupled to the computational device. The wireless communications device is configured to transmit detection of damage to the grid circuit.
A computer-implemented method, according to one embodiment, includes monitoring a grid circuit positioned in a tire to detect damage to conductors of the grid circuit, detecting damage to at least one of the conductors of the grid circuit, and transmitting information about the damage to a computer of a vehicle.
A computer-implemented method, according to one embodiment, includes receiving, from a computational device coupled to a grid circuit in a tire, information about damage to the grid circuit and outputting an indication that the tire is damaged.
Other aspects and embodiments of the present invention will become apparent from the following detailed description, which, when taken in conjunction with the drawings, illustrate by way of example the principles of the invention.
The following description is made for the purpose of illustrating the general principles of the present invention and is not meant to limit the inventive concepts claimed herein. Further, particular features described herein can be used in combination with other described features in each of the various possible combinations and permutations.
Unless otherwise specifically defined herein, all terms are to be given their broadest possible interpretation including meanings implied from the specification as well as meanings understood by those skilled in the art and/or as defined in dictionaries, treatises, etc.
It must also be noted that, as used in the specification and the appended claims, the singular forms “a,” “an” and “the” include plural referents unless otherwise specified. It will be further understood that the terms “comprises” and/or “comprising,” when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.
The following description discloses several preferred embodiments of systems, methods and computer program products for detecting tire punctures.
In one general embodiment, an apparatus includes a grid circuit having dimensions corresponding to an inner surface of a tire, a computational device coupled to the grid circuit, and a wireless communications device coupled to the computational device. The wireless communications device is configured to transmit detection of damage to the grid circuit.
In another general embodiment, a computer-implemented method includes monitoring a grid circuit positioned in a tire to detect damage to conductors of the grid circuit, detecting damage to at least one of the conductors of the grid circuit, and transmitting information about the damage to a computer of a vehicle.
In yet another general embodiment, a computer-implemented method includes receiving, from a computational device coupled to a grid circuit in a tire, information about damage to the grid circuit and outputting an indication that the tire is damaged.
Foreign objects may become embedded in a tire and cause damage to the tire and/or to other components of the vehicle. Drivers may not be immediately aware of a puncture in a tire due to distractions on the road, sealants in the tire which prevent drastic changes in tire pressure, the speed of travel, etc. Operating a vehicle with a tire puncture increases the likelihood of a blowout of the tire, resulting in a dangerous situation and/or a relatively more expensive repair.
Conventional methods of detecting and repairing tire punctures require dismounting the entire wheel from the vehicle and placing the wheel in a tank of water. Escaping air from the tire puncture causes bubbles to form around the damaged area and confirm the location of the puncture. Removing the entire wheel from the vehicle is often time consuming and/or unavailable; especially when the tire puncture occurs on the side of the road. A tub of water or equivalent mechanism is not always accessible on the road. Conventional methods of detecting and repairing tire punctures leave few options other than limping the vehicle to the nearest tire repair facility (while risking further damage to the vehicle) and/or requesting road side assistance services which may be expensive and/or inaccessible.
In many cases, non-sidewall punctures may be easily repaired on the road using conventional tire repair kits. The difficulty of locating the tire puncture deters many users from attempting repairs on the road.
In many situations, the driver is not immediately aware of the tire puncture. Many drivers rely on the Tire Pressure Monitoring System (TPMS) to detect a change in tire pressure below a hardcoded threshold. The TPMS does not provide puncture warnings to the drivers. The hardcoded threshold may be too high for a driver to be immediately aware of a tire puncture. Relying on the TPMS may result in significant tire damage from unknowingly driving with a tire puncture until the tire pressure is low enough to cause a TPMS notification. Low pressure in the tire will eventually destroy the inner liner and/or the reinforcing cords of the tire. The tire may blow out and cause a dangerous event on the road.
Various embodiments of the present invention detect a tire puncture, alert a user to the tire puncture immediately, and provide the user with the radial location of the puncture without having to uninstall the tire. Early detection of tire puncture may reduce the risk that the tire is damaged beyond repair and may improve the efficacy of tire repair performed on the side of the road.
The apparatus 100 includes a grid circuit 102 having dimensions corresponding to an inner surface of a tire 104. In a preferred approach, the grid circuit 102 has a circumference about equal to the inner surface circumference of the tire 104 and a width about equal to the inner surface width of the tire 104. The tire 104 may be of a vehicle, trailer, motor vehicle, aircraft, etc.
In one embodiment, the apparatus 100 comprises an adhesive layer coupled to the grid circuit 102. The adhesive layer may be configured to adhere the grid circuit 102 to the inner surface of the tire 104. The grid circuit 102 may be coupled to an inner surface of a tire 104 using any adhesive element known in the art.
In another embodiment, the grid circuit 102 may be integrated into the tire. For example, the grid circuit 102 may be integrated into the tire 104 as part of the injection molding process of the tire. The grid circuit 102 may be embedded into the tire 104 in any manner known in the art.
The grid circuit 102 may include circuitry of uniquely identifiable, electrically conductive “breakable” wires along the x-axis and y-axis of the grid circuit 102 where the dimensions of the squares of the grid are at least 1 mm×1 mm. In a preferred embodiment, the dimensions of the squares of the grid are no greater than 1 mm×1 mm such that a puncture by an item comprising a relatively small circumference (e.g., for example, a nail) disrupts at least one wire in the grid circuit 102. The wires may be insulated so as not to contact other wires within the grid circuit 102. Relatively small amounts of current may be applied to each wire within the grid circuit 102 in order for a computational device 106 (to be discussed in further detail below) to substantially constantly monitor resistance readings. In one configuration, each conductor line (e.g., wire) represents a coordinate point in the x-axis and the y-axis. The associations between the conductors and the coordinates may be stored in the computational device 106. The associations may be stored in any manner known in the art. In a preferred approach, the associations are stored in a table.
In a preferred embodiment, the grid circuit 102 is an installable layer of circuitry outlined in a relatively high resolution grid configuration for detecting tire punctures which penetrate the grid configuration. In a preferred embodiment, the resolution of the grid is high enough such that a puncture substantially anywhere in the grid circuit may contact at least one wire in the grid circuit.
The apparatus 100 includes a computational device 106 coupled to the grid circuit 102. The computational device 106 may be any computational device known in the art. The computational device 106 may perform at least some of the operations disclosed in method 200 and/or method 300. In a preferred embodiment, the computational device 106 includes storage for information associated with the grid circuit 102. The computational device 106 may measure and/or store resistances across each conductor within the grid circuit 102. The computational device 106 may measure and/or store resistances substantially constantly, periodically, at a time interval set by the user, the manufacturer, the default settings, etc.
The apparatus 100 includes a wireless communication device 108 coupled to the computational device 106. The wireless communication device 108 is configured to transmit detection of grid circuit 102 damage. The wireless communication device 108 may be a Bluetooth device, a radio frequency identification tag (RFID) tag, or any wireless communication device known in the art.
The apparatus 100 includes a gyroscope 110. The gyroscope 110 may be used to detect roll, pitch, yaw, etc. movements. The gyroscope 110 may be any rotational gyroscope, vibrational gyroscope, optical gyroscope, etc. In a preferred embodiment, the gyroscope 110 is configured to provide information about at least an orientation of the tire. Information about at least an orientation of the tire may be used to indicate where a tire puncture occurs according to various embodiments of method 200 and/or method 300.
The apparatus 100 includes a power source 112. The power source 112 may be a battery, a thermoelectric generator, or any power source known in the art. In a preferred embodiment, the power source 112 is a low current power source which is independent of any power source of a vehicle associated with the tire 104.
In various approaches, the locations of the computational device 106, the wireless communication device 108, and the power source 112 are balanced (e.g., substantially evenly spaced) along the inner surface of the tire 104. In a preferred configuration, the computational device 106, the wireless communication device 108, and the power source 112 are at triangular opposing locations on the inner surface of the tire 104 to minimize balance disturbance imposed on the wheel.
In various approaches, the apparatus 100 may include a vehicle associated with the tire having a computer configured to output an indication that the grid circuit 102 has been damaged. The computer may be any computer known in the art. In various approaches, the computer may output audio, visual, audiovisual alerts and/or information about the damage. In a preferred approach, the computer is configured to output a three-dimensional (3D) visual indication of the radial degree location of the tire puncture through the grid circuit 102. The 3D visual indication may be updated in real time to reflect the orientation of the tire and the tire puncture as the vehicle continues to move. The updating of orientation may be based on the gyroscope 110 readings and/or information derived from the computational device 106.
In some approaches, the apparatus 100 and/or at least some of the components of the apparatus 100 (e.g., for example, the grid circuit 102) are one-time-use products to be replaced after a tire puncture. In other approaches, the apparatus 100 and/or at least some of the components of the apparatus 100 (e.g., for example, the grid circuit 102) may be rebuilt and/or reused.

Each of the steps of the method 200 may be performed by any suitable component of the operating environment. For example, in various embodiments, the method 200 may be partially or entirely performed by computers, or some other device having one or more processors therein. The processor, e.g., processing circuit(s), chip(s), and/or module(s) implemented in hardware and/or software, and preferably having at least one hardware component may be utilized in any device to perform one or more steps of the method 200. Illustrative processors include, but are not limited to, a central processing unit (CPU), an application specific integrated circuit (ASIC), a field programmable gate array (FPGA), etc., combinations thereof, or any other suitable computing device known in the art.
As shown in
Various operations of method 200 may be performed by a computational device (e.g., see
Monitoring a grid circuit positioned in a tire includes measuring resistances across conductors of the grid circuit in order to detect changes in resistance. At least one of the conductors of the grid circuit may be disturbed and/or broken as a result of a tire puncture through the grid circuit. Damage to at least one of the conductors may disrupt the flow of current through the grid circuit.
Operation 204 includes detecting damage to at least one of the conductors of the grid circuit. In response to a puncture of a foreign object into the tire, one or more of the conductors in the grid circuit may be disturbed and/or broken. In various approaches, a computational device integrated with the grid circuit detects a change in resistance across the conductors. In a preferred approach, each conductor is uniquely identifiable by location in the x-axis and the y-axis of the grid circuit. A gyroscope sensor integrated with the grid circuit may provide the roll, pitch, and/or yaw measurements and/or data derived from the foregoing measurements including at least an orientation of the tire. In a preferred approach, the radial degree location of the tire puncture is based on the location of the damaged conductors and information derived from the gyroscope sensor readings.
Operation 206 includes transmitting information about the damage to a computer of a vehicle. Information about the damage may include the time of the puncture, the location of the vehicle when the puncture occurred, the size of the puncture, etc. In one embodiment, the information includes a location corresponding to a location of the damage to the conductors of the grid circuit. The location of the damage may be in terms of the x-axis and y-axis of the grid circuit, a corresponding location on the tire, a location in relation to parts of the tire, etc. In a preferred embodiment, the location is derived in part from the gyroscope information. In another preferred embodiment, the information about the damage includes the radial degree location of the tire puncture based on the location of the damaged conductors and information derived from the gyroscope sensor readings.
In one embodiment, the information may be transmitted by a wireless communications device (e.g., see
In another approach, the information about the damage includes a substantially immediate (e.g., within one revolution of the tire) alert to the driver that the tire is punctured. In a preferred approach, a substantially immediate alert may be sent to the driver within 30 seconds of the puncture. In other approaches, the alert may be periodically sent to the driver based on a predefined time period, constantly set to the driver based on a predefined time period, etc., until the driver pulls the vehicle over and the tire ceases to rotate. The alert may include a recommendation that the driver pull the car over to safety, a recommendation to repair the tire, instructions on how to repair the tire, etc. In one approach, the alert may indicate that the puncture is not suitable for repair (e.g., based on the size and/or location of the tire puncture) and include information regarding the nearest tire repair facility, available roadside assistance services, etc. For example, a large tire puncture may not be repairable with conventional tire repairs kits, sidewall punctures may not be repairable due to safety concerns, etc.
In another approach, operation 206 may include transmitting information about the damage to any remote device. For example, information about the damage may be transmitted to a remote cellular device of a user associated with the vehicle.
In one embodiment, a power source (e.g., for the grid circuit, the computational device, and/or the wireless communication device, etc.), the computational device, and the wireless communications device are located in the tire at triangular opposing locations. In another embodiment, the power source, the computational device, and the wireless communications device are balanced (e.g., substantially evenly spaced) along the grid circuit and the inner surface of the tire.

Each of the steps of the method 300 may be performed by any suitable component of the operating environment. For example, in various embodiments, the method 300 may be partially or entirely performed by computers, or some other device having one or more processors therein. The processor, e.g., processing circuit(s), chip(s), and/or module(s) implemented in hardware and/or software, and preferably having at least one hardware component may be utilized in any device to perform one or more steps of the method 300. Illustrative processors include, but are not limited to, a central processing unit (CPU), an application specific integrated circuit (ASIC), a field programmable gate array (FPGA), etc., combinations thereof, or any other suitable computing device known in the art.
As shown in
Operation 304 includes outputting an indication that the tire is damaged. In a preferred embodiment, operation 304 is performed by the computer of the vehicle. The indication that the tire is damaged may include a visual indication of a location on the tire corresponding to the damage to the grid circuit. In other approaches, the indication may include an audio alert, a visual alert, a textual alert, or any combination of the foregoing alerts. In a preferred configuration, the indication may include the radial degree location of the tire puncture represented as a three-dimensional (3D) visual indication of the tire and the tire puncture. The 3D indication may include a representation of the radial degree location of the tire puncture which may be used to quickly find and repair the tire puncture without removing the entire wheel from the vehicle.
In one embodiment, the indication may include instructing the user of the vehicle to move the vehicle slightly forward and/or backward in order to easily access the tire puncture (e.g., rotate the tire puncture from directly under the vehicle to a forward-facing or backward-facing position which is substantially perpendicular to the ground).
In another approach, the information about the damage includes a substantially immediate alert to the driver that the tire is punctured. The indication may include a recommendation that the driver pull the car over to safety, a recommendation to repair the tire, instructions on how to repair the tire, etc. In one approach, the indication may indicate that the puncture is not suitable for repair and include information regarding the nearest tire repair facility, available roadside assistance services, etc.
In another approach, the indication may be output to any remote device. For example, information about the damage to the tire may be transmitted to a remote cellular device of a user associated with the tire.
