A real time tire pressure sensing system includes sensors to collectively generate signals corresponding to a contained tire air temperature, a contained inflation pressure, and an ambient temperature associated with a tire mounted on a vehicle. A processor determines an effective tire inflation pressure based on the generated signals and further at least on a calculated moving average of the ambient temperature (e.g., over a defined time period such as 24 hours) and generates real time notifications associated with the determined effective tire inflation pressure to specified user interfaces. At least one sensor may be an inflation pressure sensor configured to generate event-based signals corresponding to detected changes per unit pressure. The processor may further generate real time feedback control signals to an automatic tire inflation device, based on the determined effective tire inflation pressure, or enable and prompt manual control of the tire inflation device via the user interface.

A tire pressure control system can include a pneumatic line with a first end in fluid communication with an interior of a tire and a pressure sensing device configured to acquire pressure data within the tire measured from the single pneumatic line. A motion sensing device can be configured to acquire motion data of the tire pressure control system. A microcontroller can receive the pressure data from the pressure sensing device and the motion data from the motion sensing device. A pneumatic solenoid in fluid communication with a second end of the single pneumatic line can be in an initial, closed position. The microcontroller can open the pneumatic solenoid and release fluid from the interior of the tire when the pressure data and motion data meet preset conditions.

Embodiments of the present disclosure relate generally to generating and utilizing three-dimensional terrain maps for vehicular control. Other embodiments may be described and/or claimed.

A regulator for establishing outlet fluid pressure. The regulator includes a valve body having a fluid pressure inlet in selective fluid communication with a fluid pressure outlet. A pilot pressure inlet is formed in the valve body and in fluid communication with a source of pilot pressure. Valving structure in the valve body establishes outlet fluid pressure as a function of pilot pressure. First adjustable structure within the valve body may establish a minimum outlet fluid pressure threshold without regard to pilot pressure. Second adjustable structure within the valve body may establish outlet fluid pressure offset relative to pilot pressure.

A tire has a carcass with a tread, a bead, a shoulder, and a sidewall. The bead, shoulder, and sidewall partially define a first internal cavity. At least one stiffening line for a pressurized fluid with a second cavity is within the carcass. The second cavity is aligned in an approximately transverse direction relative to the periphery of the tire. The second cavity is connectable to pressurized fluid supply system and can be inflated or deflated to adjust the stiffness of the tire. The stiffening lines may be inflated using a hydraulic fluid to increase the stiffness of the tire. Related wheels, vehicles, and methods are also disclosed.

A vehicle (100) may include one or more image sensors (110) configured to provide sensor image data (112d) representing a sensor image of a vicinity of the vehicle (100), and one or more processors (120) configured to determine one or more obstacles (132) from the sensor image data (112d), to determine a distance from ground for each of the one or more obstacles (132) based its corresponding image object (114), and to trigger a safety operation when the distance from ground is equal to or less than a safety height associated with the vehicle (100). A method for avoiding a collision of a vehicle with one or more obstacles.

The present invention relates to a control unit for determining a value indicative of a load bearing capability of a ground segment supporting a vehicle. The control unit is configured to issue a control signal to the vehicle to thereby impart a motion change of the vehicle, and receive response information from the vehicle indicative of the vehicle's response to the imparted motion change. The control unit is further configured to, based on the response information, determine a vertical position change of at least one wheel of the vehicle, and based on the determined vertical position change and the imparted motion change, determine the value indicative of the load bearing capability of the ground segment.
