  • Patent number: 8632314
    Abstract: The invention reduces waste of flow volume of pressurized oil discharged from a hydraulic pump when the rotational speed of a cooling fan is increased to the target rotational speed. The target rotational speed of the cooling fan is set at a target rotational speed setting portion. An acceleration pattern for increasing the cooling fan to the target rotational speed is set at an acceleration pattern setting portion based on the rotational speed of the cooling fan, the target rotational speed set at the target rotational speed setting portion, and magnitude of force due to inertia of the cooling fan and the hydraulic motor. The rotational speed command value calculation portion controls the pressurized oil to be supplied to the hydraulic motor at a flow rate required. Thus, it is possible to reduce wasted relief flow volume.

  • Patent number: 8548693
    Abstract: A control device for a work machine on a construction vehicle is provided so that a bucket cylinder is stopped at a target position, with high accuracy achieved in a bucket cylinder length, and with chock held down to a low level. A bucket cylinder length detection section refereces a cylinder length detection table on the basis of a boom angle and a bell crank angle, thereby detecting a bucket cylinder length. A bucket attitude control section controls the bucket cylinder length so that a target position will be reached. Feedback control is performed until a set value which is set short of a target value is reached. After the bucket cylinder length reaches the set value, open loop control is performed until the target value is reached.

  • Patent number: 8464672
    Abstract: A variable valve timing control apparatus adjusts the rotation phase (VCT phase) of an engine camshaft by selectively supplying oil to an advancement chamber and a retardation chamber, and includes a lock pin which is controlled for being moveable to a first position, in which the rotation phase is adjustable, and a second position, in which the camshaft is locked at a specific rotation phase. When the lock pin is displaced from the first position, oil becomes enabled to pass between the advancement chamber and retardation chamber, to thereby enabling the rotation phase to be changed to the specific rotation phase by supplying oil to an appropriate one of the advancement chamber and a retardation chamber, for initiating locking.

  • Patent number: 8463525
    Abstract: A control device projects a lock pin to lock a VCT phase in an intermediate lock phase when a lock request occurs. A learning unit learns one of a most retarded phase, a most advanced phase, and an intermediate lock phase, as a reference phase. A control unit sets a target phase according to the reference phase and controls the control device. A monitor unit determines that the VCT phase has passed through the intermediate lock phase when the lock request occurs before completion of learning of the reference phase, and when a change in the VCT phase becomes greater than a threshold. The threshold is set to be greater than a sum of i) a design value of a phase difference between the intermediate lock phase and one of the most retarded phase and the most advanced phase and ii) a range of a product variation of the phase difference.

  • Patent number: 8240279
    Abstract: An engine valve control device is applied to an engine valve control mechanism having a VVT (valve timing adjusting device), an OCV (control valve) that controls a flow of hydraulic oil supplied to the VVT, and an electromagnetic solenoid that controls an operation of the OCV according to a control duty (control command value). The engine valve control device calculates the control duty based on a holding duty, which occurs when an actual phase does not change but is held, and feedback correction values. The engine valve control device corrects the value of the holding duty in accordance with a steady-state deviation between the actual phase and a target phase to perform learning for storing and updating the holding duty value. If temperature of the hydraulic oil is low, the learning is prohibited even when the steady-state deviation is occurring.

  • Patent number: 8215272
    Abstract: In a variable valve timing control apparatus, a hydraulic variable valve timing device adjusts valve timing by changing a VCT phase. In a lock mode, the lock pin is allowed to be displaced in a lock direction for locking the VCT phase, and the VCT phase is slightly shifted in a lock-mode VCT phase shift direction corresponding to one of an advance direction and a retard direction. A lock control unit shifts the VCT phase in a direction opposite from the VCT phase shift direction if the VCT phase is located on a lock-mode VCT phase shift direction side of the intermediate lock position when the engine becomes equal to or less than a first rotational speed, and otherwise the lock control unit allows the lock pin to be displaced in the lock direction.
