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.

Abstract: A vehicle control device includes a processor and memory. The memory stores relation-defining data for defining a relation between a state of a vehicle and an action variable that is a variable relating to operations of a transmission installed in the vehicle. The processor is configured to execute acquisition processing, operation processing, reward calculation processing, updating processing, counting processing, and limiting processing. The processor is configured to output the relation-defining data updated so that an expected income is increased when the transmission is operated following the relation-defining data, based on an updating map.

Abstract: A regenerative torque upper limit is set to a larger value when a rear-wheel distribution ratio is small than when the rear-wheel distribution ratio is large. Accordingly, when a distribution of a drive power to front wheels is large, a regenerative torque of a second rotary machine can be increased such that wheels are less likely to slip at the time of performing of regeneration control when the distribution of the drive power to the front wheels is small in comparison with a case in which the regenerative torque upper limit is set to a constant value similarly to when the distribution of the drive power to the front wheels is small. In this way, it is possible to increase the regenerative torque of the second rotary machine according to the rear-wheel distribution ratio.

Abstract: A vehicle including an internal combustion engine and an automatic transmission capable of transmitting and receiving torque to and from an output shaft of the internal combustion engine is controlled. During operation of the internal combustion engine, a process that calculates a diluted water amount based on an operation state of the internal combustion engine is executed. The diluted water amount is the amount of water contained in lubricating oil in the internal combustion engine. Further, a process that controls the automatic transmission such that torque per unit period in the internal combustion engine becomes smaller when the diluted water amount is relatively large compared to when the diluted water amount is relatively small, while continuing the operation of the internal combustion engine, is executed.

The control device establishes, as drive modes driving a vehicle, a first drive mode controlling a torque distribution ratio between front wheels and rear wheels by putting the vehicle in all-wheel drive state by power from the second power source while controlling the first engagement device to be in slip state with the second engagement device kept in engaged state, and a second drive mode putting the vehicle in all-wheel drive state by power from the first power source while fixing the torque distribution ratio with both the first engagement device and the second engagement device kept in engaged state.

Abstract: The apparatus according to the present invention includes a rotatable leg-holding wheel for holding the legs of the bird. Said leg-holding wheel is mounted close to both the terminal portion of the defeathering line and the initial portion of the eviscerating line and operates to cause the birds to transfer from the defeathering line onto the eviscerating line. On the frame for the leg-holding wheel are fixedly mounted an engaging guide member for guiding the bird suspended from the defeathering shackle and for causing it to engage the leg-holding notches of the leg-holding wheel, a cutter for cutting the ankles of the bird engaged by the leg-holding notches to release the bird from the defeathering shackle, and an inclining guide member and a releasing guide member which coact to release the bird held in the leg-holding notches and cause it to engage with the eviscerating shackle.
