To provide a circuit with low power consumption, a semiconductor device with low power consumption, a highly reliable semiconductor device, a tire whose performance is controlled, a moving object whose performance is controlled, or a moving object with a high degree of safety. A tire provided with a semiconductor device is provided. The semiconductor device includes a circuit portion, an antenna, and a sensor element. The circuit portion includes a transistor. The transistor includes an oxide semiconductor. The sensor element is configured to measure the air pressure of the tire.

A multi-chambered wheel assembly may include a wheel rim and a tire mounted on the wheel rim. The tire and the wheel rim may define an interior chamber. A divider wall may be disposed in the interior chamber. The divider wall may define a fill chamber and a gas cavity. A gas valve may be communicated with the gas cavity. The gas valve may be configured to allow pressurized gas to be introduced into the gas cavity. A fill valve may be communicated with the fill chamber. The fill valve may be configured to allow fill material to be introduced into the fill chamber.

Method and apparatus are disclosed for controlling a TPMS sensor of a vehicle tire. An example vehicle includes a communication module, a tire, and a TPMS sensor corresponding to the tire. The TPMS sensor is configured to receive a target pressure from the communication module, determine a modified target pressure based on vehicle data determined by a vehicle sensor, and, responsive to determining that a measured pressure differs from the modified target pressure by a threshold amount, transmit an alert to the communication module.

Method for coupling a tractor with a semi-trailer and semi-truck with a tractor and a semi-trailer.

An aerodynamic system comprising a torsion tube, a first rotatory coupling coupled to the torsion tube and adapted to mount to a first wheel hub, a second rotary coupling coupled to the torsion tube distal from the first rotary coupling and adapted to mount to a second wheel hub, and a non-rotating fairing panel mounted to the torsion tube.

An integrated tire inflation valve comprises an inlet configured to receive air from an air tank, a pressure protection assembly configured to control air flow into the tire inflation system when an air pressure reaches a pre-set pressure level, a valve assembly in fluid communication with the pressure protection assembly, a pressure regulator configured to be adjusted to a desired pressure to thereby allow air through the pressure regulator at a desired level, a flow switch configured to selectively allow air therethrough, and an outlet configured to provide air from the flow switch to one or more tires of a vehicle. The inlet, pressure protection assembly, valve assembly, pressure regulator, flow switch, and outlet are all positioned within a single housing.

A tire pressure controlling device for a tire of a vehicle wheel filled with compressed air, includes a control valve unit for filling the tire with compressed air and/or venting compressed air therefrom. The control valve unit is supplied from a compressor for generating the tire filling pressure. The compressor for compressing air drawn in from the atmosphere is driven by the mechanical rotary movement of the vehicle wheel, as a transmission disposed therebetween transmits the rotary driving movement of the vehicle wheel to the drive shaft of the compressor unit.

The invention relates to a method for associating tire sensor modules (6.i) with a trailer vehicle (3), having at least the following steps: capturing data messages (S1) from tire sensor modules (6.i, 106.i, 206.i) in a monitoring region (8); associating the captured data messages (S1) with a tire sensor module (6.i, 106.i, 206.i); ascertaining a number of captured data messages (S1) for each detected tire sensor module; rating the captured data messages (S1) to establish whether the tire sensor modules (6.i, 106.i, 206.i) received in total up to then belong to the driver's own trailer vehicle (3) or to the adjacent trailer vehicle (103, 203); accepting the tire sensor modules (6.i) detected in the rating as affiliated to the driver's own trailer vehicle (3).

According to the invention, each tire sensor module (6.i, 106.i, 206.i) detects a wheel position associated with the respective tire sensor module (6.i, 106.i, 206.i) and a trailer axle configuration, so that for an accepted tire sensor module (6.i) the wheel position and the trailer axle configuration can be taken as a basis for making a positional association on the driver's own trailer vehicle (3).

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.

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.
