A control device for a vehicle power transmitting apparatus is disclosed, having an electrically controlled differential portion operative to control an operating state of an electric motor to control a differential state, and a shifting portion forming part of a power transmitting path between the electrically controlled differential portion and drive wheels, which can minimize deterioration in power performance and degradation in controllability during the shifting. Shift interval altering means 70 is provided for altering an interval L from an operation initiation causing an automatic shifting portion 20 to execute a shifting, to an actual shift initiation depending on a kind of the shifting. This enables an appropriate interval L to be determined for the shifting, thereby obtaining adequate power performance while capable of avoiding a first electric motor M1 from operating in a region outside an operating range. Thus, degradation in controllability is minimized.

A lock-up clutch control device which controls a lock-up clutch provided in a torque converter installed between an engine and a transmission, is disclosed. The lock-up clutch control device changes over between a converter state and a lock-up state of the torque converter according to a differential pressure command value (LUprs) relating to a differential pressure supplied to the lock-up clutch. The lock-up clutch control device includes a differential pressure generating device (7, 8) which generates the differential pressure supplied to the lock-up clutch; input torque detection means (2, 14, 15) which detects an input torque (Te) to the torque converter; and a controller (1). The controller (1) is programmed to compute a real differential pressure (P_lu) based on the detected input torque (Te) upon completion of the engagement of the lock-up clutch; compute a learning value (P_learn(Tai)) relating to a differential pressure deviation, based on the difference between the computed real differential pressure (P_lu) and differential pressure command value (P_ref) upon completion of the engagement of the lock-up clutch, and store the learning value (P_learn(Tai)); correct a present differential pressure command value (LUprs_slp) based on the learning value (P_learn(Tai)); and send the corrected differential pressure command value (LUprs) to the differential pressure generating device (7, 8).

A control device for hybrid vehicle drive apparatus is disclosed which executes an internal-combustion-engine rotation control for rotating an engine output shaft (94) under a circumstance where a consecutive travel distance LM involved in a motor drive running mode exceeds a given consecutive travel distance determining value L1. The rotation of the engine output shaft (94) results in an effect of accelerating the lubrication of an engine (8). Once the engine output shaft (94) is rotated, no component parts of the engine (8) actually take the completely same attitudes at time before and after such rotation. This avoids the component parts of the engine (8) from continuously remaining contact with each other in the same attitudes when encountered with running vibrations during the motor drive running mode, minimizing adverse affect on durability of the engine (8) due to the running vibrations occurring in the motor drive running mode.

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.

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.

A driving device for a hybrid vehicle includes a transmission unit configured to output a rotation of an engine while changing rotating speed of the engine; and a first rotating electric machine. The first rotating electric machine is configured to supply a torque for increasing the rotating speed of the engine at the time of starting up of the engine to the engine through the transmission unit. At the time of starting up of the engine, the gear shift stage of the transmission unit is switched to an overdrive state. Thus, a torque sufficient for starting up of the engine can be supplied to the engine, and hence the engine can be appropriately started up.
