A wheel rim generator is provided, including: a wheel rim having a rim, a disc, and an axis of rotation; a bearing having an outer race and an inner race, said inner race is disposed around said rim within the rim width; a rotor configured to rotate with said outer race, has at least one permanent magnet, and a center of gravity being displaced from said axis of rotation; and a stator configured to rotate with said rim, form at least one magnetic circuit with said rotor, and generate electromotive force with one of constant and changing magnetic flux in said at least one magnetic circuit as said wheel rim rotates.

A vehicle includes a sprung mass including a cabin coupled to a chassis, tractive assemblies engaging the chassis, each tractive assembly including a pair of tractive elements, gas springs coupling the tractive elements to the sprung mass, and a controller operatively coupled to pressure sensors. Each gas spring is configured to impart an upward force on the sprung mass. The upward force varies based on a pressure of a pressurized gas within a chamber of the gas spring. Each pressure sensor is configured to provide a signal indicative of the pressure of the pressurized gas within one of the chambers. The controller is configured to determine a weight of the sprung mass using the signals from the pressure sensors. The controller is configured to monitor at least one operational condition of the vehicle and determine whether or not to disable determination of the weight based on the operational condition.

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

A vehicle is provided and includes a first tire, a second tire, and a detector that is configured to detect an air pressure of the first tire. A vibration generator is configured to generate vibration in the second tire. A controller is configured to operate the vibration generator to cause the second tire vibrate when the air pressure of the first tire satisfies a predetermined normal condition.

A method for adapting a tire inflation pressure of an agricultural vehicle includes ascertaining a current vehicle position by a navigation system, correlating the current vehicle position by a control unit with a cartographically captured field boundary, detecting a travel-induced entry into a cultivation region surrounded by a field boundary, and selecting a set tire inflation pressure designated for field cultivation from a database by the control unit. The method further includes applying the selected set tire inflation pressure to at least one tire of the agricultural vehicle by a tire-pressure regulating system.

A tire inflation system for use with a vehicle includes an airflow regulator configured to adjust a tire pressure of an inflatable tire coupled to an axle included in a wheel-axle system of a vehicle. The tire inflation system may further include a controller including a processor and a memory, the memory having stored therein a plurality of instructions that when executed by the processor cause the controller to receive data indicative of a force load acting on the axle and adjust the airflow regulator to cause the airflow regulator to control the tire pressure of the inflatable tire based on the data indicative of the force load acting on the axle.

An automatic tire inflation system for an agricultural implement is provided. The automatic tire inflation system includes a first sensor configured to detect a weight of the agricultural implement. The automatic tire inflation system also includes a controller configured to receive feedback from the first sensor and to automatically adjust a pressure of one or more tires of a plurality of tires coupled to the agricultural implement based on at least the weight of the agricultural implement.

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.

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.

An apparatus and method is provided that includes measuring a tire pressure for at least one tire with at least one tire pressure sensor. The tire pressure sensor has at least a first resolution for transmitting pressure information and a second resolution for transmitting pressure information that is higher than the first resolution. If a measured tire pressure is determined to be above a predetermined pressure threshold, the apparatus and method identify whether the tire pressure sensor has experienced at least one predetermined vehicle operating characteristic, and/or identify whether the tire pressure sensor has been activated by a command. The tire pressure sensor is only locked into the second resolution if the tire pressure sensor has experienced the at least one predetermined vehicle operating characteristic or if the tire pressure sensor has been activated by the command.
