Abstract: A vehicle control apparatus configured to selectively establish one of a first drive state in which a vehicle drive force is generated primarily by a second motor/generator operated with an electric energy supplied from an electric-energy storage device while an engine is placed in a rest state, and a second drive state in which a first motor/generator is operated with a drive force of the engine, to generate an electric energy and in which the vehicle drive force is generated primarily by the second motor/generator operated with at least the electric energy generated by the first motor/generator. The vehicle control apparatus is further configured such that the vehicle drive force generated in the second drive state at a given value of an accelerator pedal operation amount θacc is larger than that generated in the first drive state.

Abstract: Because an EOP starts operating from when a decrease in discharge flow rate of an MOP is predicted or detected, a PL actual pressure that should be obtained with a PL command pressure set to a value for a required transmission torque is more easily maintained even when the discharge flow rate of the MOP becomes insufficient. After a lapse of a predetermined period of time from the start of operation of the EOP, the PL command pressure is temporarily set to a value higher than the value for the required transmission torque, and a regulator valve is controlled to operate to close a drain port. Therefore, the operation of the EOP in a high PL actual pressure is reduced, and a delay in response of a pressure regulating operation of the regulator valve in the process of reduction of the discharge flow rate of the MOP is reduced.

Abstract: A friction plate (11) includes a plate (1A) with a disc shape and a friction material (F1, F2) that is fixed to aside face (1a) of the plate (1A). The friction material (F1, F2) is disposed so that one or both of an inner peripheral side and an outer peripheral side is nonuniform in an inner and outer peripheral direction with respect to a circumferential direction around a center (CT1) of the plate (1A). Thus, there is an increase in the amount of lubrication oil that is fed to a surface of friction material segments (F1, F2) and there is an increase in a separation force in an axial direction between a friction plate (11) and a separator plate or an end plate.

Abstract: When a noise generation duration time predicted by a prediction unit is equal to or less than a predetermined time and it is predicted that generation of noise can be further curbed in comparison with a case in which the noise generation duration time in which noise is generated is relatively short and the noise generation duration time is greater than the predetermined time, an engine operating point control unit controls an engine and a differential unit such that an engine operating point reaches an engine operating point in an optimal fuel-efficiency operating line and thus it is possible to curb generation of noise and to curb a decrease in fuel efficiency.
