摘要： A control apparatus (80; 122) for a hybrid vehicle (10; 100) provided with an engine (14; 102) and an electric motor (MG2; MG) which function as a drive power source, and an automatic transmission (20; 110) which is placed in a selected one of speed positions with engagement of selected at least one of coupling devices (CB), the control apparatus including: an input torque control portion (84) to control the electric motor for controlling an input torque (Ti) transmitted to the automatic transmission (20; 110) during a shifting action of the automatic transmission, on the basis of an output torque (Te) of the engine and a torque (Tcb) transmitted through the coupling devices, such that a value representing a rotating state of an input rotary member (30; 124) of the automatic transmission coincides with a target value. The input torque control portion (84) controls the input torque so as to be not smaller than a predetermined lower limit, when a running state of the hybrid vehicle (10; 110) is switched from a power-on state to a power-off state during a shift-down action of the automatic transmission in the power-on state.

摘要： 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.

摘要： A control apparatus (80) for a vehicle (10; 100) having an electric motor (MG2; MG), and a step-variable transmission (20; 110) which is selectively placed in a plurality of speed positions with engagement of at least one of a plurality of coupling devices (CB), wherein the vehicle runs rearward with a reverse drive torque (TmR) of the electric motor generated in a forward-drive low-speed position of the transmission. The control apparatus includes: a first shift control portion (86) operated during a coasting shift-down action of the transmission to the low-speed position and configured to temporarily increase the forward drive torque (TmF) of the electric motor above its required value, for thereby temporarily increasing an input torque of the transmission to raise its input speed toward a synchronizing speed in the low-speed position. The first shift control portion commands an engaging-side coupling device, which is one of the coupling devices for the forward-drive low-speed position and which was placed in its released state before the shift-down action, to be brought into its engaged state after the input speed has been raised to a predetermined value; and a second shift control portion (88) operated when switching to rearward running of the vehicle is required during the coasting shift-down action and configured to increase an engaging force of the engaging-side coupling device, for thereby raising the input speed of the transmission toward the synchronizing speed, to bring the engaging-side coupling device into the engaged state.

摘要： A vehicle control apparatus selects one of a power-on control and a power-off control for execution of a shift-down action in a transmission of a vehicle, and implements the selected power-on or power-off control. When a running speed of the vehicle is not lower than a predetermined value, the control apparatus selects one of the power-on control and the power-off control, based on a target input torque that is to be inputted to the transmission. When the vehicle running speed is lower than the predetermined value, the control apparatus selects one of the power-on control and the power-off control, based on an actual input torque that is actually inputted to the transmission.
