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.

A method is for monitoring tire states and/or sensor states. The method includes the steps: a) capturing whether at least one tire sensor module for measuring tire states and/or sensor states is present in a monitoring region; b) determining whether the captured tire sensor module is unknown; c) evaluating data messages from the at least one captured and unknown tire sensor module, the evaluation including at least comparing at least one tire state transmitted via the data message with a limit value therefor and/or monitoring a sensor state of the tire sensor module transmitted via the data message; and, d) outputting a warning signal if a tire state exceeds or undershoots the respective limit value in order to indicate that a tire state of a tire assigned to the at least one unknown tire sensor module is critical and/or if a critical sensor state is detected.

In a method for assisting a driver of a vehicle, a closed loop control device and/or open loop control device is switchable into multiple warning stages such that: if at least one temperature value measured by a temperature sensor exceeds a first defined threshold value, the closed loop control device and/or open loop control device switches into a first warning stage in which it is indicated to the driver to stop the vehicle within a defined period of time and/or within a defined section of road and/or that the driver is not to exceed a defined speed value. If the measured temperature value exceeds a second defined threshold value, greater than the first threshold value, the closed loop control device and/or open loop control device switches into a second warning stage in which it is indicated to the driver that the driver is to stop the vehicle immediately.

A tire air pressure monitoring system for a vehicle is disclosed. The tire air pressure monitoring system includes a detector configured to detect tire air pressures of tires of the vehicle; and a processing device. The processing device is configured to output a first notification that is an alarm representing a reduced tire air pressure state based on at least one of the tire air pressures less than or equal to a first threshold, detect a predetermined opportunity at which the tires can be filled with air, and output a second notification, differently from the first notification, based on a detection of the predetermined opportunity and at least one of the tire air pressures less than or equal to a second threshold but greater than the first threshold, the second threshold being greater than the first threshold.

The present disclosure provides a vehicle-mounted monitoring device and a vehicle-mounted monitoring system. The vehicle-mounted monitoring device includes a main body detachably arranged on a vehicle, and the main body is arranged with a circuit board, a display screen, a first communication module and a second communication module, and the display screen, the first communication module and the second communication module are all electrically connected to the circuit board. The first communication module is configured to receive image data wirelessly transmitted from at least one camera and then transmit the image data to the circuit board, the second communication module is configured to receive tire pressure data wirelessly transmitted from at least one tire pressure sensor and then transmit the tire pressure data to the circuit board, and the circuit board transmits both the image data and tire pressure data to the display screen for display.

A tire inflation pressure management apparatus includes an information acquisition unit, an alert generation unit, and an alert output unit. The information acquisition unit acquires information on a tire inflation pressure measured by a sensor provided in a tire. The alert generation unit generates alert information when the tire inflation pressure acquired by the information acquisition unit is below a first threshold value smaller than an appropriate value of the tire inflation pressure. The alert output unit gives a notification outside after an elapse of a predetermined period to indicate that the alert information is generated by the alert generation unit during the predetermined period.

A warning control unit of this tire air pressure monitoring device starts giving a driver a tire air pressure fall warning when a tire air pressure is equal to or lower than a first threshold. The warning control unit stops the warning when the tire air pressure becomes equal to or higher than a second threshold that is set based on a tire temperature in a case where the warning is being given. The warning control unit uses a constant value unrelated to a detected tire temperature as the first threshold, and uses a value obtained by adding a variable value, which is obtained by adding a positive constant value to a value that increases as a temperature difference obtained by subtracting a tire temperature at the time of the issuance of the warning from a current tire temperature increases, to the first threshold, as the second threshold.

Disclosed herein are system and method embodiments for monitoring tire conditions. For example, the system includes a sensor that is configured to: receive light that is reflected off of at least one object within a field of view (FOV) that is adjacent to a vehicle as reflected light, and provide tire data indicative of a distance between the sensor and a surface of a tire of the vehicle extending into the FOV based on the reflected light. A controller is configured to generate a message in response to a moment of a probability distribution of the tire data being less than a threshold, or tire data indicative of a rate of change of shadow length exceeding a threshold shadow length, and to provide the message to at least one of a user interface, a vehicle system, and an external computing device.

A tire pressure monitoring system includes tire pressure sensors installed within vehicle tires, a receiver, an alerting device, an electronic input/output device and an electronic controller. The receiver receives tire pressure signals from the tire pressure sensors, The electronic input/output device provides manual input of instruction and data. The electronic controller is configured to monitor tire pressure and in response to tire pressure in each of vehicle tires achieving a change from a first preset tire pressure to a second preset tire pressure the alerting device is operated to alert a person changing the tire pressure that the change has been achieved. The first preset tire pressure corresponds to paved road driving conditions and the second preset tire pressure corresponds to off-road driving conditions.
