Abstract

Systems and methods for improving hybrid vehicle shifting are presented. Specifically, torque supplied to an input shaft of a transmission may be adjusted during torque and inertia phases of a transmission gear shift. The torque supplied to the transmission input shaft may be increased or decreased based on the shift and the shift phase.

Description

technical field [0001] The present invention relates to systems and methods for improving shifting of a multi-speed transmission of a hybrid vehicle. The method is particularly useful for hybrid vehicles that include an electric motor or generator that can be selectively coupled to the engine. Background technique [0002] A hybrid vehicle may be configured with an engine, a driveline disconnect clutch, a driveline integrated starter / generator (DISG), and a dual mass flywheel positioned upstream of the transmission. This driveline configuration allows the engine and DISG to operate individually or together to propel the vehicle, and to store the vehicle's kinetic energy as electrical energy to propel the vehicle at a later time. The driveline configuration may provide versatility during a variety of driving conditions; however, the driveline configuration may have increased inertia compared to a driveline that includes only the engine and transmission. The increased inerti...
