摘要： Systems and methods for operating a driveline disconnect clutch of a hybrid vehicle are presented. In one example, a driveline disconnect clutch is de-stroked in a particular way so that the driveline disconnect clutch may be de-stroked more consistently. The de-stroking process may be followed by boosting and stroking the driveline disconnect clutch so as to preposition the driveline disconnect clutch or holding the clutch at an offset below stroke pressure to minimize drag.

摘要： An apparatus for determining a failure of an engine clutch is provided. The apparatus includes an engine clutch that is disposed between an engine generating power and a motor and a driving information detector that senses driving information including a shift speed stage, an engine speed, a motor speed, a SOC of a battery, and a vehicle speed. A controller then determines a driving mode of the engine from the detected driving information and determines whether oil leakage of the engine clutch is generated from the driving information and the driving mode.

摘要： Systems and methods for improving operation of a hybrid vehicle are presented. In one example, application of a driveline disconnect clutch to start an engine is described. The approach applies the driveline disconnect clutch to rotate an engine and at least partially disengages the driveline disconnect clutch to reduce the possibility of a reduction in torque applied to vehicle wheels.

摘要： A vehicle includes an engine, transmission, engine control module (ECM), and transmission control module (TCM). The transmission includes an input member and an input clutch which selectively connects a crankshaft of the engine to the input member. The TCM identifies a target clutch torque of the input clutch during a creep maneuver of the vehicle, and communicates the identified target clutch torque to the ECM. The ECM maintains engine idle speed at a threshold level through the creep maneuver and a requested launch using the target clutch torque as a feed-forward term. A method includes identifying a target clutch torque of the input clutch during a creep maneuver, and communicating the identified target clutch torque to the ECM. The idle speed is maintained at a threshold level by the ECM through the creep maneuver and a detected launch using the target clutch torque as a feed-forward idle speed control term.

摘要： When an engine stop control is executed while an automatic ratio shift portion is in a neutral state, a switching clutch is operated, so that a differential portion carrier of a differential portion planetary gear device that is linked to an engine, and a differential portion ring gear linked the automatic ratio shift portion are integrally rotated. Therefore, along with the engine stop control, the rotation speed of the rotating elements of the differential portion planetary gear device is reduced while the rotating elements are integrally rotated or substantially integrally rotated. Since the rotating elements are rotated integrally or substantially integrally, the high rotation speed of the differential portion ring gear linked to the automatic ratio shift portion, which tends to have a heightened rotation speed particularly during the neutral state, is prevented.

摘要： A control apparatus for a vehicular automatic transmission, which permits effective reduction of deterioration of vehicle drivability upon operation of a brake operating member, and which is configured to increase a sweeping rate in a sweep control of the torque capacity of a coupling element of an automatic transmission portion 20 to be engaged to perform a shifting action when a regenerative braking command is generated according to the operation of the brake operating member during an inertia phase of the shifting action, so that the coupling element is rapidly engaged for the purpose of generating an engine braking force when the regenerative braking command is generated according to the operation of the brake operating member during the inertia phase of the shifting action. Accordingly, the braking force generated during the shifting action is equal to the braking force generated in the normal state (in the absence of the shifting action).
