摘要： A controller (5) performs open loop control of the engaging state of a lockup clutch (2) through a switching mechanism (3, 4) when a torque converter (1) transitions from a first state in which the lockup clutch (2) is disengaged to a second state in which the lockup clutch (2) is at least partially engaged. At this time, the controller (5) estimates the engine torque at the time when open loop control ends, estimates a necessary lockup capacity required for the converter (1) at the time when open loop control ends, based on the estimated engine torque, and controls the engaging state of the lockup clutch (2) through the switching mechanism (3, 4) to make the lockup capacity at the time when open loop control ends become the necessary lockup capacity.

摘要： In lock-up capacity control apparatus and method for a torque converter, the torque converter is caused to have a converter state in which a relative revolution between input and output elements of the torque converter is free of limitation in a case where a lock-up capacity (L/Uprso) during a no-load state is equal to or larger than a shock determining lock-up capacity (α), during an acceleration slip lock up in which the lock-up capacity of the torque converter is augmented by means of a time series control which accords with a load state of an engine, and the torque converter is caused to be oriented toward a lock-up state in which the relative revolution is zeroed by continuing an augmentation of the lock-up capacity by means of the time series control in a case where the lock-up capacity during the no-load state is smaller than the shock determining lock-up capacity.

摘要： A vehicle-drive-device control device controls an operating point of the engine by adjusting a torque of a first electric motor, such that a sum of the engine torque and the first electric motor torque is balanced with a torque of an input-side rotating element of a fluid transmission device, which is generated depending on a speed ratio of the fluid transmission device. The control device obtains the input-side rotating element torque based on the engine rotation speed indicated by a target engine operating point, and to determine the first electric motor torque based on the obtained torque and the engine torque indicated by the target engine operating point. The control device adjusts the first electric motor torque while giving/receiving the electric power between the first and second electric motors, to make the speed ratio lower when a temperature of operating oil is low, than when the temperature is high.

摘要： In a drive system, a first differential mechanism transmits engine rotation, a second differential mechanism connects the first differential mechanism with drive wheels, and a switching device changes a speed ratio of the first differential mechanism. The second differential mechanism has first, second, and third rotational elements, which connect respectively to the first differential mechanism, a first rotating machine, and a second rotating machine. In a first running condition, the vehicle runs using the second rotating machine as a power source, while differentially operating the first differential mechanism. In a second running condition, the vehicle runs using the second rotating machine as a power source, without differentially operating the first differential mechanism. A region in which the vehicle runs in the second running condition in the case where the engine cannot start by itself is larger than that in the case where the engine can start by itself.
