A controller of a four-wheel drive vehicle includes a first operation part that switches drive mode of the vehicle; a second operation part that switches off-road traveling modes indicating traveling modes for off-road driving of the vehicle; a transfer controller that controls the arrangement of a transfer device in accordance with the drive mode; a detector that detects the arrangement of the transfer device; a determiner that determines whether a switching of the traveling modes is permitted or not based on the drive mode and the arrangement detected by the detector; and a setter that sets the traveling modes of the vehicle based on the detected arrangement and input operations to the first operation part and the second operation part when the determiner determines the switching of the traveling modes is permitted, and maintains the current traveling mode when the determiner determines the switching of the traveling modes is not permitted.

Controller of four-wheel drive vehicle

In a 2H mode of two-wheel drive and a 4H mode of four-wheel drive, a driver does not put much importance on traveling performance on a rough road. Therefore, implementation of both of idling-stop control and neutral control is permitted. Compared with the 4H mode, in a 4HLc mode for limiting differential motions of a center differential gear and a rear differential gear, it can be regarded that the driver puts importance on the traveling performance on the rough road. Therefore, the implementation of the idling-stop control is prohibited and the implementation of the neutral control is permitted. In a 4LLc mode for switching a sub-reduction gear to a low gear side compared with the 4HLc mode, since it can be regarded that the driver puts more importance on the traveling performance on the rough road, both of the implementation of the idling stop control and the implementation of the neutral control are prohibited.

Vehicle control device

A drive force adjustment apparatus includes a differential gear, a motor, a first gear mechanism and a second gear mechanism. The input element, the first output element, the second output element, the motor input element, the fixed element, and the connecting element are expressed as points I, R, L, M, F and C on a graph, an ordinate of which shows the number of revolutions and a abscissa of which shows relative ratios of the number of revolutions of the elements. Length of L-I is equal to length of R-I, I is located between L and R on a straight line L-R, I is located between F and C on a straight line F-C, and R is located between C and M on a straight line C-M.

In one example, length of L-I is equal to length of R-I, I is located between L and R on a straight line L-R, C is located between L and M on a straight line L-M, and C is located between F and I on a straight line F-I.
