Abstract: An apparatus for sensing pressure in vehicle tires includes an interrogator (102) for providing a tire pressure interrogation signal, and a tire pressure monitor (70) for sensing pressure within a first tire (24) of the vehicle (20) and providing an actual tire pressure signal. A first wheel speed sensor (42) associated with the first tire (24) provides a reference wheel speed signal upon movement of the vehicle (20). A second wheel speed sensor (40) associated with a second tire (22) of the vehicle (20) provides a wheel speed signal upon movement of the vehicle. A controller (60) activates the interrogator (102), monitors the actual tire pressure signal, and correlates the reference wheel speed signal with the wheel speed signal from the second wheel speed sensor (40) for determining a tire pressure value of the second tire (22).

Abstract: A system and method for monitoring vehicle tire pressure. A tire pressure monitor for each tire includes a pressure sensor for sensing tire pressure, a transmitter for transmitting a tire pressure signal representative of the sensed tire pressure, and a batter providing power to the transmitter. To conserve battery power, each tire pressure signal transmitted by the transmitters includes a wake-up signal only when the vehicle has been stationary for a predetermined time period. The wake-up signal ensures receipt of the tire pressure signal by a vehicle mounted receiver alternating between active state and inactive states.

Abstract: Tire air pressure during high speed travel is estimated without a sensor for detecting the tire air pressure directly. An apparatus is constituted by a wheel speed sensor, road surface friction state estimator for estimating a friction state estimation value representing friction between the tire and a road surface from wheel speed detected by the wheel speed sensor, tire air pressure estimator for estimating any reduction in the tire air pressure based on the friction state estimation value, and a display for displaying the estimated reduction in the tire air pressure.

Abstract: A tire safety system mounts on a vehicle wheel rim inside a pneumatic tire. A tire air pressure sensor produces a tire air pressure reading mounted inside the tire. An inflatable member forms a toroidal expandable internal safety structure. The inflatable member is mounted against the vehicle wheel rim. The chemicals container inside the inflatable member receives an electrical signal at an activation input. The chemicals container creates pressurized gas inside the inflatable member for inflation when a signal is received at the activation input. A circumferential radially expandable protective belt mounted around the inflatable member expands with inflatable member inflation to accommodate operation the tire when expanded. A computer receiving tire air pressure readings from the tire air pressure sensor sends a signal to the activation input upon a sudden change in tire air pressure.

Abstract: Disclosed herein is a method and apparatus for monitoring the air pressure of a tire. Various colors are displayed by the apparatus to denote an inflation level of the tire, and the apparatus may remain coupled to the air nozzle of a tire indefinitely. The apparatus may include a diaphragm that deforms in response to an air pressure differential on opposing sides thereof. Deformation of the diaphragm may alter the position of a color indicating cup, such that a color is displayed through an observation window, informing a user as to the inflation state of the tire.

Abstract: A remote tire pressure monitoring system and method for installing the system are disclosed. The remote tire pressure monitoring system includes a pressure monitor, a tire valve assembly including a valve stem, a retention nut, and a plastic thin-walled valve cap which fits on an open end of the valve assembly. The outer diameter of the thin-walled valve cap is smaller than the inner diameter of the retention nut. As a result, the retention nut fits over the thin-walled valve cap. The tire pressure monitoring system is installed on a tire rim by threading the tire valve assembly with the valve cap in place through an opening in the tire rim and then passing the retention nut over the valve cap and tightening the retention nut onto the valve stem.

Abstract: In a system for remote monitoring of tire pressure in a vehicle having front tires including a right tire and a left tire, and rear tires including a right tire and a left tire, a system and method are provided for automatically identifying tire location. A transmitters mounted in each tire transmits tire information signals conveying tire pressure data and associated tire rotation direction data. A vehicle mounted receiver has a location a first distance from the front tires and a second distance from the rear tires, the first distance being different from the second. A vehicle mounted controller in communication with the receiver determines whether pressure data is associated with a front tire or a rear tire based on the strength of the tire information signal, and whether pressure data is associated with a right tire or a left tire based on the associated rotation direction data.
