The disclosed technology generally relates to tires, and more particularly to a method of and a smart tire system for evaluating a state of a tire, and providing an alarm, and to a smart tire configured for the method and the system. In one aspect, a method includes determining whether an abnormality or a problem exists in a state of a tire, by processing a tire state value from a TPMS sensor. Processing the tire state can be carried out by a sensor processor and/or a sensor information processor. The method additionally includes providing an alarm to a user, e.g., a driver. The method additionally includes verifying the determination of whether there is an abnormality or a problem. Thus, the disclosed method includes determining the state of a tire and providing an alarm, where the alarm has high reliability because it is generated based on examination of various parameters of the tire state, including, e.g., pressure, temperature and/or acceleration. The disclosed technology additionally relates to a system and a smart tire configured to implement the method. The method, the system and the tire according to embodiments may be improvements over existing methods, systems and tires.

Provided is a parking assistance device using a tire pressure monitoring system (TPMS), which accurately calculates a moving distance of a vehicle by reflecting a tire pressure received from the TPMS and performs parking control in response to a parking command generated by using a parking route and a position of the vehicle estimated by the calculated moving distance of the vehicle, thereby improving automatic parking performance of the vehicle to a parking space. The parking assistance device calculates a moving distance of a vehicle moving to a found parking space around the vehicle according to a tire pressure of the vehicle, estimates a position of the vehicle by using the calculated moving distance, and generates a parking command. The moving distance of the vehicle is calculated by using a moving distance per revolution of a tire measured and set according to a tire pressure range to which the tire pressure of the vehicle belongs, a wheel pulse of the tire of the vehicle, and a reference wheel pulse per revolution of the tire.

A patch-type passive acoustic waving sensing device includes a surface acoustic wave sensor and at least a first and second rubber sheets. A cross-section of each of the first and second rubber sheets is larger than that of the surface acoustic wave sensor. A bottom of the surface acoustic wave sensor is on an upper surface of the first rubber sheet, and a first central hole allowing the surface acoustic wave sensor to penetrate therethrough is formed in a center of the second rubber sheet. The surface acoustic wave sensor penetrates the first central hole, and the second rubber sheet is fixedly connected to the upper surface of the first rubber sheet. The surface acoustic wave sensor includes pins at the bottom thereof such that free ends of the pins are connected to an antenna, and the antenna and some of the pins are inside the first rubber sheet.

A vehicle includes a detection unit configured to detect a state of the vehicle, a transmission unit configured to transmit information based on a result of the detection performed by the detection unit to an image display device, and a control unit configured to change information to be transmitted to the image display device when a power supply of the vehicle has changed from an on state to an off state.

A rapid inflation system is provided for the tires of a machine such as an agricultural machine which must periodically move between field conditions and road conditions. The system can relatively rapidly inflate the tires from a lower field ready state to a higher pressure road ready state by the use of a high pressure reservoir chamber defined within the tire.

An information acquisition device is provided within a virtual plane including a coil axis of a coil-shaped antenna and having a perpendicular line orthogonal to an axis of rotation of a tire, such that the angle formed by the coil axis of the antenna relative to the tire rotational axis is within a range of 0° to 40°. The amount of attenuation of radio waves emitted from the antenna to the exterior of the tire is thereby reduced.

A tire pressure control arrangement for a vehicle having at least two tires connected to an air supply. Each tire is connected to the air supply via a supply line having a first valve connected to a second valve. The arrangement further includes a pressure sensor between the two valves. The first valve is closed while the supply line is connected to a pressure supply and the pressure in the supply line is monitored for a pre-determined period of time by a control system on the vehicle to detect whether there are any leaks in the arrangement.
