Systems, methods, and computer-readable storage media for using multi-stage machine learning algorithms to optimize tire contact patches on a vehicle. Vehicle sensors first collect vehicle information for the vehicle, and input that data into a first machine learning algorithm. The first machine learning algorithm then outputs a lateral dimension, a longitudinal dimension, and a diagonal dimension, which together identify a tire contact patch of at least one tire on the vehicle. The operator of the vehicle provides a human preference for how the vehicle operates, and a second machine learning algorithm is executed. The second machine learning algorithm inputs can include the plurality of vehicle information, the first machine learning algorithm outputs, and the human preference, and the second machine learning algorithm outputs can include a desired tire pressure of the at least one tire and an air suspension adjustment for the normal load of the vehicle.

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 method for determining the loading of a tire (1) mounted on a vehicle (9) and running along the ground, said tire (1) being equipped with a sensor (10), comprises: acquisition, by the sensor (10), of a measurement signal representative of the change in curvature of the tire (1) during running, determination, from the measurement signal, of measurement data comprising a first parameter representative of a length of a contact patch (6) in contact with the ground (7) during a revolution of the wheel bearing the tire, and determination of the loading of the tire (1) as a function of the first parameter, of the internal pressure of the tire, and of a firmness factor representative of a condition of firmness of the ground, which is derived from measurements taken while the tire is rolling over said ground.

A safety valve replaces a tire valve. The valve includes a generally elongate hollow main body having an upper portion, a lower flex hose connector, a side tubular branch having a valve seat with a ball valve, an electronics housing having a battery, motor and a drive pin for the ball valve. The lower flex hose connector is adapted for connection to a flex hose or valve stem of the vehicle tire. The side branch branches from the main body and communicates with the hollow interior of the main body. The side branch has a plurality of air exit apertures at its periphery. The valve seat includes a base with an aperture therein through which the drive pin can extend through to engage the ball valve. The ball valve sits in the base and is biased in the valve seat via a spring to cover the aperture.

A method and system of preventing or reducing water ingress into a tire inflation system is provided.

One or more techniques and systems are described herein for synchronized air delivery method between a vehicle's central tire inflation system (CTIS) and an air trailer brake (ATB) system. A synchronized air delivery system can utilize a shared air source as a common shared input to drive two different systems, including the ATB system and CTIS. Based on ATB and CTIS air need feedback, an air compressor clutch can automatically control ON and OFF modes for air inputs using a control algorithm. Air can be provided to the ATB system, to provide air to brakes on a coupled trailer, over the tire inflation operation, such as during a braking event.

A load sensitive ride system and method is disclosed for a vehicle with an implement movably attached by a boom cylinder. The system includes a payload weight measuring system that measures payload weight and generates a signal indicative of the payload weight, a ride control circuit that adjusts hydraulic flow to and from the boom cylinder; and a controller that receives the signal indicative of the payload weight, and sends compliance commands to adjust ride control compliance based on the signal indicative of the payload weight. The system can include a tire inflation system that adjusts tire pressure. The controller can send inflation commands to adjust tire pressure based on the signal indicative of the payload weight. The compliance commands can depend on the components and compliance adjustment methods of the ride control circuit.

Systems and methods for determining the health of a seal in a tire inflation system are provided. In one example, a method of determining the health of a seal of a tire inflation system on a vehicle includes obtaining one or more pressure measurements of a tire of the vehicle with a pressure transducer in communication with an electronic control unit and sending the one or more pressure measurements to a computer network via a communication network that receives signals from the electronic control unit, the communication network including a telematics device in communication with the computer network, wherein the computer network is configured to determine the health of the seal based on the one or more pressure measurements communicated by the telematics device.

An agricultural vehicle is operable in a first state for transport and in a second state for field work and includes a frame supported by a plurality of tires. A processor is operable to receive a signal generated as a result of the agricultural vehicle transitioning from the first state to the second state or from the second state to the first state. A gas system is operable to modify the tire pressure of the plurality of tires of the agricultural vehicle in response to the signal.

A system for detection of non-pneumatic tire loading includes a non-pneumatic tire. The non-pneumatic tire includes a ground-contacting annular tread, a central rim, and at least one spoke disk disposed between the rim and the tread. The spoke disk includes an inner ring mounted on the central rim, an outer ring, and spokes extending radially between the inner ring and the outer ring. A shear band is disposed between the outer ring of the spoke disk and the tread. A flange is disposed on an outboard surface of the spokes of the spoke disk. Indicating means are formed on the outboard surface of the plurality of spokes of the spoke disk radially outwardly of the flange. The flange interfaces with the indicating means when the tire is in an overloaded state or is in need of replacement.
