  • Patent number: 11958471
    Abstract: A four-wheel drive vehicle includes: a drive-power distribution device for distributing a drive power from an engine to main and auxiliary drive wheels with a drive-power distribution ratio between the main drive wheels and auxiliary drive wheels; and a control apparatus for controlling an electric motor such that the drive-power distribution ratio becomes a target distribution ratio value, by setting an electric-current command value for driving an electric motor. The control apparatus is configured, in a drive-power transmitted state in which the drive power is transmitted to the drive-power distribution device, to execute a command-value reduction control operation for causing the electric motor to be driven with the electric-current command value being set to a value smaller than in a drive-power non-transmitted state in which the drive power is not being transmitted to the drive-power distribution device.

  • Patent number: 11208040
    Abstract: Provided is a display system, which makes it easy for an operator to accurately grasp a traveling situation of a work vehicle. A front camera captures an excavating blade and topography in front of a crawler dozer. A rear camera captures a fuel tank and a ripper apparatus, and a topography behind the crawler dozer. A display image displayed on a monitor is generated by arranging a front image captured by the front camera and a rear image captured by the rear camera so that the excavating blade in the front image may face the fuel tank in the rear image.

  • Patent number: 10882491
    Abstract: A lock device includes a locking member, a movable member, and a transmission mechanism. The locking member is moved between a lock position at which it locks a locking subject and an unlock position at which it unlocks the locking subject. The transmission mechanism transmits a drive force to the movable member and moves the movable member. A movement state of the movable member is shifted between a relative movement state in which it is moved relative to the locking member and an integral movement state in which it is moved together with the locking member to move the locking member toward the lock or unlock position. The lock device further includes a detector of which an output value varies in accordance with movement of the movable member or the transmission mechanism, and a controller that performs a failure determination based on a change in the output value.
