    摘要: A four-wheel drive vehicle is provided, including an engine with an operating mode that is switchable between all-cylinder and reduced-cylinder operating modes, a torque transmission assembly for transmitting an output torque of an engine to main drive wheels and auxiliary drive wheels, a torque ratio adjusting device included in the torque transmission assembly and configured to adjust a ratio of the output torque distributed to the auxiliary drive wheels, and controller that executes a noise suppression module for increasing the torque ratio provided to the auxiliary drive wheels by the torque ratio adjusting device so as to suppress noise generation at the torque transmission assembly, in the all-cylinder and reduced-cylinder operating modes. The noise suppression device changes the torque ratio provided to the auxiliary drive wheels according to engine operating ranges where the torque transmission assembly is in a noise generating state in the all-cylinder and reduced-cylinder operating modes, respectively.

    摘要: When an operating point that is determined by the engine speed (Ne), the engine torque (Te), and the vehicle speed falls within the zones of both a first vibration risk region (α1) and a second vibration risk region (α2), the dwell time (ΔT1) thereof is measured, and once this dwell time (ΔT1) reaches a predetermined vibration assessment time (ΔT1_Lim), the gear ratio of the continuously variable transmission is corrected towards the large side (low side) so that the operating point is moved out of the vibration risk regions (α1, α2).

    摘要: A control system in a vehicle in which at least one pair of driving power transmission members are engaged with each other with a slack on a driving power transmission path, comprises an input shaft rotational speed detector for detecting a rotational speed of an input shaft located upstream of engaged portions of the driving power transmission members in a direction in which the driving power is transmitted, a determiner for determining whether or not the driving power transmission members are in a non-contact state at the engaged portions for a period of time based on a change rate of the detected input shaft rotational speed, and a controller for controlling the vehicle to reduce a rotational speed difference between the input shaft and an output shaft located downstream of the engaged portions, when the determiner determines that the driving power transmission members are in the non-contact state.
