An inflation electronic control module for a tire inflation system is described. The inflation electronic control module may be configured to initiate a warning that indicates a problem with a vehicle tire based on tire inflation fill events and collected fill event data. Automatic tire inflation and data recording systems including an inflation electronic control module are further described. The control module may include an electronic control board configured for recording a log of fill event data for tire inflation fill events, the electronic control board being configured for wireless transmission of fill event data to a remote computer.

A compressor assembly (10) for supplying pressure medium to a tire cavity (7) of a tire of a vehicle wheel, which can be mounted on a wheel hub (4) that is mounted on a wheel carrier (3) for rotation about an axis of rotation (32). The compressor assembly (10) includes a hub-side compression chamber (16) and a compressor component (18). A pressure medium is conducted into the tire cavity (7) upon being pressurized in the compression chamber (16) by oscillating translational motion of the compressor component (18). The compressor assembly (10) includes a transmission (20) that converts a rotational motion between the wheel carrier side and the wheel hub side into an oscillating translational motion of the compressor component (18) when a hub-side transmission part (24) is in an operating position with a wheel-carrier-side transmission part (26).

A chamber is provided that works as a peristaltic pump for the pressure correction in the tire, which is a part of the tire or of an ancillary structure placed between the rim and the tire bead and is connected with the tire internal space at one end and with the external environment at the other end. The chamber is in the shape of a curved hollow channel, where at least one enclosing wall is at least partially formed by at least a pair of surfaces coplanar with the longitudinal direction of the chamber. When the tire is mounted on the rim, the pair of surfaces are pressed together thus hermetically closing the chamber. When the chamber is closed during rotation of the wheel, the surfaces can slightly slide on one another taking internal wall tensions onto themselves thus decreasing the possibility of wall damage through ripping.

A device for adjustment of pressure in tires includes a chamber with shape memory and a valve. The valve is a three-way valve with inputs interconnected with the external environment and the tire internal space, where one input is fitted with a valve, the next input is connected to one end of the chamber with shape memory, and the last input is interconnected with the closure element. The device for adjustment of pressure in tires includes the chamber with shape memory interconnected with the external environment through an input and with the tire chamber through an output and fitted with at least one valve. The length of the chamber in the direction of tire rotation equals 0.001 to 0.5 of the tire perimeter, where the volume of the chamber before deformation to volume of the chamber during deformation ratio is the same or higher then the desired tire pressure to pressure of the external environment ratio.

A tire pressure system for a vehicle includes an inflation/deflation system that includes a compressor and a valve in fluid communication with four tires. Each of the four tires have a tire pressure. At least one sensor is configured to receive at least one of vehicle location data, vehicle environmental data and other sensor information. A controller is in communication with the inflation/deflation system and the at least one sensor. The controller is configured to select at least one of the four tires to adjust the tire pressure of the selected at least one of the four tires. The controller is configured to control at least one of the valve and compressor to achieve at least one of desired fuel economy and desired road control of the selected at least one of the four tires.

A device for maintaining and changing the pressure in a is provided whereby the inner pressure space of the tire is connected through a pump to a pressure accumulator which, at its input and/or output into the inner pressure space of the tire, is fitted with at least one pressure control element. The pump can be a peristaltic pump in the shape of a deformable hose placed on the perimeter of the tire, fitted with an air inlet and an air outlet, while the air inlet and the air outlet are positioned on the perimeter of the tire distant from each other by a preset length, dependent on the deformation of the tire.

An inflation electronic control module for a tire inflation system comprising a solenoid valve disposed so as to selectively open or close fluid communication between a fluid pressure source and a vehicle tire in response to one or more pressure signals. The tire inflation system further comprising a fluid pressure sensor disposed so as to detect delivery-side fluid pressure between the solenoid valve and the vehicle tire, and provide a pressure signal corresponding to the detected fluid pressure.
