Embodiment Construction

[0038] The present invention relates to controlling the drive train of a hybrid vehicle. Such as Figure 1-3 As shown, the hybrid vehicle may include an engine and an electric motor. The engine may or may not be run with a driveline integrated starter / generator (eg, an electric motor or motor, which may be referred to simply as DISG) during vehicle operation. The driveline integrated starter / generator is engaged into the driveline on the same axis as the engine crankshaft and turns whenever the torque converter impeller rotates. Also, DISG may not selectively engage or disengage the driveline. Rather, the DISG is an integral part of the drive train. Also, the DISG can be operated with or without the engine running. The mass and inertia of the DISG belongs to the driveline to provide or absorb torque from the driveline when the DISG is not operating.

[0039] The drive train can be Figure 4 method runs. In some examples, the drive train may be based on Figure 5-10 Dri...

Abstract

The invention provides a system and a method for improving the operation of a hybrid vehicle. In one embodiment, compensation for a power train disconnect-type clutch is provided. The method can reduce torque interference of a power train.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Provisional Patent Application 61 / 643,137, filed May 4, 2012, the entire contents of which are hereby incorporated by reference for all purposes. technical field [0003] The present invention relates to systems and methods for improving the drivability and fuel economy of vehicles. This approach may be particularly useful for engines that are selectively connected to an electric motor and a transmission. Background technique [0004] Some hybrid vehicles may include a driveline disconnect clutch that may mechanically isolate one portion of the driveline from a second portion of the driveline. For example, the engine can be selectively isolated from the transmission and wheels via a driveline disconnect clutch, so the transmission and wheels can operate independently of the engine. The driveline disconnect clutch enables torque to be provided to the driveline to propel the vehic...
