Abstract: An apparatus for monitoring the condition of a pneumatic tyre including a pressure sensor(s) to measure an internal pressure within the tyre. A speed sensor(s) measures a rotational speed of the tyre. A controller is configured to receive data from the pressure sensor and the speed sensor and output indications related to a condition of the tyre. The controller determines the output indications by tracking the internal pressure with respect to time during use of the tyre, identifying at least one change in internal tyre pressure in a time interval. The time interval is between a first reference time and a second reference time, the reference times corresponding to points at which the speed sensor indicates different rotational speeds of the tyre. The controller further monitors the pressure change as a function of rotational speed of the tyre to provide an indicator of tyre condition.

Abstract: The invention relates to a method for monitoring the wear of a motor vehicle tire. According to the invention, the method comprises the following steps of:



acquiring (step E1), from a tangential acceleration signal of said monitoring module, measurements of a variable in the group comprising a maximum tangential acceleration peak and a minimum tangential acceleration peak,
performing (step E2) processing of said measurements of said acquired variable,
comparing (step E3) said processed measurements to a predetermined maximum variation threshold value,
transmitting a warning (step E4) when said predetermined maximum variation threshold value is reached.




The invention also relates to a tire pressure monitoring module for implementing said method.

Abstract: An air pressure abnormality determination system determines whether an air pressure abnormality in which an air pressure of at least one of multiple front tires and multiple rear tires drops. The front tires are front wheels of a vehicle. The rear tires are rear wheels of the vehicle and of which outer diameter is different from an outer diameter of the front tires. A determination is made on whether the air pressure abnormality occurs using a corrected wheel speed obtained by correcting one of a front wheel speed that is a wheel speed of the front wheels and a rear wheel speed that is a wheel speed of the rear wheels based on the outer diameter of the front tires and the outer diameter of the rear tires and an uncorrected wheel speed that is the other of the front wheel speed and the rear wheel speed that is uncorrected.

Abstract: An abnormality monitoring system includes gas sensors provided in the cavity or the vicinity of a tire provided in a vehicle, a determination unit that determines the presence of an abnormality in the tire on the basis of the detection results of the gas sensors, and an output unit that outputs data based on the determination result of the determination unit. The gas sensors detect a volatile substance when abnormal heat build-up occurs in the tire. The volatile substance is a substance derived from an additive added when a tire is manufactured.

Abstract: A method for reading pressure may include reading, by a first device, an acceleration of a pressure sensor, wherein the pressure sensor is encapsulated in a medium, and wherein the acceleration alters a reading of the pressure sensor and reading, by a second device, a pressure reading from the pressure sensor. If an output criteria is met, an adjusted pressure reading is produced. A system for reading pressure includes a first device coupled to the pressure sensor and configured to read an acceleration of the pressure sensor. A second device may be configured to read a pressure from the pressure sensor wherein, if an output criteria is met, to adjust the measured pressure of the pressure sensor, based on the measured acceleration, to produce an adjusted pressure reading. An output device is configured to receive an output of the second device and to output an output pressure reading.

Abstract: Aspects of tire sensor auto-location are described. Timestamped tire acceleration values are received for a set of tire sensor devices. Each tire sensor device provides a tire-specific subset of the timestamped tire acceleration values. Vehicle configuration parameters are identified to define a number of rear axles and a number of tires or wheels on each side of each axle. The vehicle configuration parameters and the timestamped tire acceleration values are processed to identify and assign an axle position and a vehicle side position for each tire sensor device of the set of tire sensor devices.

Abstract: A system for monitoring tire tread on a vehicle may include front wheels, rear wheels, a sensor network to determine rolling radius data associated with the front wheels and the rear wheels, processing circuitry which may include a memory unit and may be configured to receive the rolling radius data from the sensor network, and a user interface which may display information to an operator of the vehicle. The processing circuitry may be further configured to determine a rolling radius of the front wheels and the rear wheels, determine a difference in the rolling radius between the front wheels and the rear wheels, compare the difference in the rolling radius to a predetermined threshold value, and generate a notification via the user interface to indicate that a tire rotation may be recommended responsive to the difference in the rolling radius exceeding the predetermined threshold value.
