A method for actuating a tire-pressure regulating system of an agricultural vehicle combination includes monitoring a current operating status of an implement by a control unit and receiving data by the control unit indicative of a change in the current operating status of the implement. The method also includes communicating a command by the control unit to a tire-pressure regulating system of the change in the current operating status and controllably adjusting a tire inflation pressure in one or more tires of a tractor or the implement by the tire-pressure regulating system based on the data received by the control unit.

A control apparatus and method for varying tire pressure can improve fuel efficiency, energy efficiency, and driving performance by applying a bimetal to a rim portion of a wheel, inducing deformation of the bimetal by applying current to the bimetal according to conditions such as driving information and road information, and individually controlling air pressures of four tires of the front and rear wheels through the deformation of the bimetal.

A vehicle includes a plurality of track systems, a fluid pump, a plurality of fluid lines fluidly connecting the fluid pump to at least some of the tires of the wheels of each of the track systems, a plurality of pneumatic inflation actuators, a plurality of pneumatic deflation actuators, and a system controller. The system controller is in electronic communication with the fluid pump, the plurality of pneumatic inflation actuators, and the plurality of pneumatic deflation actuators. The system controller is operable to selectively adjust fluid pressure in select ones of the wheels of any one of the track systems of the vehicle by actuating corresponding ones of the plurality of pneumatic inflation actuators and the plurality of pneumatic deflation actuators. A track system has at least one of the leading idler wheels, trailing idler wheels, and mid-roller wheels including a tire containing a fluid.

A repair system for a vehicle includes a base and a lift component movably secured to the base for lifting a portion of a frame of the vehicle. An air compressor unit is disposed on the base and has a discharge hose configured to be selectively connected to the tire for delivering compressed. A sealant reservoir is disposed on the base and filled with a flat tire sealant. The discharge hose is optionally configured to deliver the flat tire sealant to the tire. A controller is disposed on the base and receives tire data from the vehicle and controls discharge of the compressed air from the air compressor unit to the tire and optionally controls discharge of the flat tire sealant to the tire based on the tire data. The tire data includes a tire pressure reading associated with the tire.

Environmentally friendly electrical vehicles are presented. The electrical vehicles include electrical low speed vehicles (LSVs) that may use sensed location data to obtain one or more operational profiles. The operational profiles may govern the behavior of the LSV in a specific environment, area, or zone to ensure the LSV reduces its impact on the local terrain. The LSV may leverage locally sensed data to form a local context in which the LSV is operating. The LSV's vehicular controller may refine the operational parameters of the operational profile to ensure smooth operation based on local conditions from the local context.

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 vehicle tire pressure control system includes a road sensor configured to acquire road data regarding a road at an advanced location ahead of a current location of a vehicle; a pressure regulator configured to control the air pressure within a tire of the vehicle during operation of the vehicle; and a controller configured to control operation of the pressure regulator and vary the air pressure within the tire based on the road data.

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.

A vehicle includes a center differential device and an air pressure controller. The center differential device includes a first output shaft coupled to front wheels and a second output shaft coupled to rear wheels. The center differential device is configured to perform differential operation between the first output shaft and the second output shaft and to limit the differential operation between the first output shaft and the second output shaft. The air pressure controller is configured to control air pressure of one or more tires of the front wheels and the rear wheels such that an average rotational speed of the front wheels and an average rotational speed of the rear wheels are equal to each other.

Tire pressure regulation method and system for an agricultural vehicle equipped with tires. In order to improve the pressure management of the tires connected to the tire pressure regulation system, a pressure setpoint is determined by determining the characteristics of the tires, the pressure of which is intended to be regulated by the tire pressure regulation device, determining the speed of the vehicle, calculating the pressure setpoint of the tire depending on the characteristics of the tire and on the speed.
