    Abstract: A clutch pressure control device includes a request filter unit that calculates a target clutch pressure value from a requested clutch pressure value input in the request filter unit. A feedforward clutch pressure control model unit calculates, from the target clutch pressure value input by the request filter unit, a feedforward current value. A PID control unit calculates a feedback current value from a valve pressure target value for a hydraulic proportional valve controlling the clutch pressure and a feedback actual pressure value. A first calculation unit calculates a hydraulic proportional valve target current value from the input feedforward current value and the feedback current value. The device utilizes measurement methods to find values for a kisspoint pressure of the clutch, a preload pressure of the clutch, and a fill volume of the clutch.

    Abstract: An automatic clutch controller for a vehicle that reduces the oscillatory response to clutch engagement. The automatic clutch controller receives inputs from an engine speed sensor and a transmission input speed sensor and develops a clutch actuation signal controlling a clutch actuator from disengaged to fully engaged. The clutch engagement signal at least partially engages the friction clutch in a manner to cause the measured transmission input speed to asymptotically approach engine speed employing an approximate inverse model of this oscillatory response. The automatic clutch controller preferably includes a slip integral function and a differential engine speed function, which together adaptively adjust clutch engagement corresponding to vehicle loading. The automatic clutch controller includes a prefilter and a compensator constructed to reduce the need for detailed particularization for individual vehicles or vehicle models.A lag compensation function in the compensator adds robustness to the system by increasing low frequency gain. A freeze function suspends operation of the slip integral, the prefilter and the compensator during engine deceleration or when throttle position is high and engine speed is low, to moderate or stop clutch advance to prevent engine overloading.

    Abstract: A control device of a wheel loader obtains a first ratio between a value corresponding to a target traveling distance for the wheel loader, when it travels to a discharge position where an excavated substance is discharged after an excavation with a bucket, and a value corresponding to a target elevation amount for an elevation of a boom after a motion is started. The control device also obtains a second ratio between a value corresponding to an actual traveling distance after the wheel loader starts its motion to the position where the excavated substance is discharged after the excavation with the bucket, and a value corresponding to an actual elevation amount of the boom after the motion is started. The control device then controls a transmission toque transmitted to a drive wheel from an engine in order that a difference between the first ratio and the second ratio becomes zero.
