DIFFERENTIAL ROTATION LIMITING FORCE CONTROL APPARATUS FOR CENTER DIFFERENTIAL
A differential rotation limiting force control apparatus for a center differential includes an outwardly headed state detection processor and a limiting force control processor. The outwardly headed state detection processor makes a detection of an outwardly headed state in which a vehicle is cornering with a yaw rate and a side-slip angle of a vehicle body of the vehicle having the same sign. In response to the detection of the outwardly headed state, the limiting force control processor controls a limiting force that limits differential rotation between front and rear wheel driving devices, to reduce a difference between a motive force on a front wheel caused by an output of the travel power source and an absolute value of a braking force on the front wheel caused by internal circulation torque of the center differential.
DISCONNECTOR APPARATUS
The present invention provides a disconnector apparatus including: a support ring provided in a differential casing and configured to support a pinion gear mounted therein; a clutch ring having one end penetrating the differential casing, provided in the differential casing, and configured to be coupled to or decoupled from the support ring; an actuator configured to press the other end of the clutch ring to couple the support ring and the clutch ring; and an elastic member coupled to an exposed portion of the clutch ring positioned outside the differential casing, the elastic member having one end in contact with the differential casing and the other end in contact with the actuator.
VEHICLE WITH ENGINE POWER LIMITING BASED ON CLUTCH CAPACITY
A vehicle includes a powertrain having a powerplant and a clutch that selectively couples the powerplant to an axle. A controller is programmed to, in response to the powertrain being in a power-limiting routine, command a torque to the powerplant based on an error between a target slip of the clutch and a slip of the clutch.

Sensor abnormality determination device for four-wheel drive vehicle
A sensor abnormality determination device of a four-wheel drive vehicle including a drive source, main drive wheels and sub-drive wheels, a power transmitting member, a first connecting/disconnecting device, a second connecting/disconnecting device, a first sensor, and a rotation sensor, the sensor abnormality determination device comprises a first sensor abnormality determining portion determining that the first sensor is abnormal when the rotation sensor detects the rotation of the power transmitting member and it is presumed that the four-wheel drive vehicle is in the four-wheel drive state, when the first sensor detects that the first connecting/disconnecting device is in the disconnecting state, and when the rotation sensor detects the rotation of the power transmitting member after the second connecting/disconnecting device is switched to the disconnecting state.
Wheel speed sensing system
A wheel speed sensing system for a work vehicle having an engine, a transmission, a differential, and an axle, defining a central longitudinal axis and coupled to the differential. The wheel speed sensing system includes a sensor target disposed at the axle and a sensor configured to transmit a sensor signal, wherein the sensor is located adjacently to the sensor target. The sensor target includes a plurality of step splines each having a top surface and first and second planar sidewalls. The sidewalls of the step splines are aligned along a radius extending from the central longitudinal axis, such that the sides are undercut with respect to the top surface. An intersection of each of the sidewalls with the top surface defines an edge forming a relatively sharp transition configured to be sensed by the sensor. A chamfer at the intersection of the sidewalls and the top surface is also contemplated.
