In variants, the tire inflation system control method can include: determining a setpoint based on driving context for a vehicle; and controlling an inflator based on the setpoint. In variants, the tire inflation system can include a remote computing system and a set of wheel-end inflators mounted to the wheel ends of a vehicle and connected to the remote computing system, such as via a gateway local to the vehicle.

A vehicle includes a vehicle frame, front wheels, and rear wheels. The vehicle also includes front drive means for driving the front wheels with a front nominal speed, rear drive means for driving the rear wheels with a rear nominal speed, and control means. The control means are adapted and configured for selectively controlling the front drive means and the rear drive means so that either the front nominal speed is different from the rear nominal speed, or so that the front nominal speed is equal to the rear nominal speed.

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.

A load-based tire inflation system for a heavy-duty vehicle comprises at least one source of fluid pressure, suspension structure of the heavy-duty vehicle, a tire and wheel assembly and a system to control fluid pressure in the tire and wheel assembly. The suspension structure is located between a frame member and an axle and has a condition indicative of a weight of the heavy-duty vehicle. The tire and wheel assembly is operatively mounted to the axle and is in fluid communication with the source of fluid pressure. The control system controls fluid pressure in the tire and wheel assembly in response to the condition of the suspension structure.

A load based tire pressure regulation system for trucks or trailers employing an air spring maintained at a variable pressure P.sub.AS depending upon the load on the truck or trailer, includes an air pilot pressure regulator receiving air at pressure P.sub.AS and air at the pressure of at least one tire of a truck or trailer, and configured to feed air to and bleed air from the at least one tire of the truck or trailer as a function of the load on the truck or trailer. The pressure regulator is configured to feed air to and bleed air from the at least one tire of the truck or trailer based upon the pressure of the air spring P.sub.AS as a function of the load on the air spring (F.sub.AS), and further upon the recommended pressure P.sub.T of the at least one tire as a function of the load on the tire (F.sub.T).

An air pressure abnormality determination system determines whether an air pressure abnormality in which an air pressure of at least one of multiple front tires and multiple rear tires drops. The front tires are front wheels of a vehicle. The rear tires are rear wheels of the vehicle and of which outer diameter is different from an outer diameter of the front tires. A determination is made on whether the air pressure abnormality occurs using a corrected wheel speed obtained by correcting one of a front wheel speed that is a wheel speed of the front wheels and a rear wheel speed that is a wheel speed of the rear wheels based on the outer diameter of the front tires and the outer diameter of the rear tires and an uncorrected wheel speed that is the other of the front wheel speed and the rear wheel speed that is uncorrected.
