A tire inflation system for a work vehicle includes a controller with a memory and a processor, where the controller is configured to perform an iterative process until a stopping condition is reached. The iterative process includes receiving a tire pressure sensor signal indicative of a tire pressure a one tire, receiving a draft load sensor signal indicative of a draft load on the work vehicle, determining a draft load difference between the draft load and a maximum draft load, and outputting a target tire pressure output signal indicative of instructions to adjust the tire pressure of the tire in response to determining that the draft load difference is greater than or equal to a first threshold value.

An electronic control unit executes gradual reduction control when a friction clutch is to be maintained in a fully engaged state such that an input rotary member and an output rotary member rotate integrally. As a result, a motor current supplied to a motor is adjusted to a lower current value. Thus, an average current value of the motor current supplied to the motor when the friction clutch is to be maintained in the fully engaged state is appropriately reduced.

An outer ring of an inner joint of the constant speed transmission shaft is provided with a vehicle speed sensor rotating synchronously with the inner joint, and the drive axle is fixedly equipped with a signal collecting device opposite to the vehicle speed sensor and configured to monitor a rotation speed signal of the vehicle speed sensor. The inner joint of the constant speed transmission shaft transmits torque during the running of a vehicle, and through monitoring a rotation speed of the inner joint, the rotation data of rear wheels can be obtained. By mounting the vehicle speed sensor on the inner joint and fixing the signal collecting device on the drive axle for monitoring the rotation speed signal of the vehicle speed sensor, the signal reading is stable, which facilitates the maintenance, reduces the cost, and can satisfy the environmental requirements.

A wheel suspension system and a method for controlling the system. The wheel suspension system includes a first axle provided with wheels and a second axle provided with wheels. The first axle is connected to a first driveshaft portion via a first differential 6a and the second axle is connected to a second driveshaft portion via a second differential 6b. The system further includes angular speed sensors designed to detect the rotational speed of the axles, and/or the rotational speed of the respective wheels. The angular speed sensors are connected to an electronic control unit (ECU) which is designed to calculate a difference between the angular speed of the first and second axles, and/or a difference between the angular speed of the respective wheels by the use of input data from the angular speed sensors. The speed difference can be used as an indication of different wheel radius of the wheels. The system includes a coupling, e.g. a dog clutch arrangement, arranged in the driveshaft and positioned between the first and second drive shaft portions for changing the first and second drive shaft portions between being drivingly connected and disconnected.

A vehicle includes a vehicle body comprising a front, a first side, and a second side, wherein the first side and the second side are opposite one another on the vehicle body. The vehicle comprises a cabin located within the body of the vehicle, wherein the cabin comprises an interior that is configured to accommodate at least one person. The vehicle comprises at least one door that provides ingress and egress to the interior of the cabin of the vehicle. The vehicle comprises a windshield that provides a visual line of sight out of the cabin for a user located within the interior of the cabin, and wherein the windshield extends across the front and at least partially on to at least one of the first side or the second side.

Provided is a replacement necessity determination device for a snap-in valve having an inner end to which an air pressure detection device including an air pressure sensor and an acceleration sensor is coupled. A control device of the replacement necessity determination device is configured to predict an angle change amount of the snap-in valve and the air pressure detection device with respect to a wheel caused by a centrifugal force based on a rotational speed of the wheel and an acceleration detected by the acceleration sensor, calculate a degradation indication value of an elastic body of the snap-in valve based on a maximum value of the angle change amount during a period set in advance, and determine necessity of replacement of the snap-in valve based on an integrated value of the degradation indication value.
