Problems solved by technology

[0004] However, in an automatic manual transmission based on a synchro-shift mechanism, in the process of automatically performing a shift by an actuator, there inevitably occurs a moment at which the supply of power from the engine is stopped, and the resulting reduction in torque will Causes poor shifting feel, that is, the driver feels the vehicle is being pulled backwards

Abstract

A transmission for a hybrid vehicle may include a first input shaft continuously provided with power from an engine, a second input shaft selectively provided with power from the engine via a clutch,a counter shaft coupled to the first input shaft, an output shaft coupled to the second input shaft, a first one-way clutch disposed on a path along which power is transferred from the engine to the output shaft, a motor input shaft provided with power from a motor, a motor-side shift unit comprising a plurality of pairs of gears having different gear ratios, in which one pair of the plurality ofpairs of gears suitable to a traveling speed is selected by an engager / disengager, and a second one-way clutch disposed on a path along which power is transferred from the motor to the output shaft.

Description

technical field [0001] The present invention relates to a transmission for a hybrid vehicle that improves fuel efficiency and market competitiveness of the hybrid vehicle by operating a motor in a driving range where the engine is inefficient. Background technique [0002] Similar to an automatic transmission, an automated manual transmission provides driving convenience by allowing gears to be automatically changed via an actuator while the vehicle is running. Since the power transmission efficiency is better than that of the automatic transmission, the automatic manual transmission will contribute to the improvement of fuel efficiency. [0003] Automatic manual transmissions include hydraulic actuators used in manual transmissions, whereby the process of changing gears by controlling gears can be performed automatically by a transmission control unit (TCU), thus replacing the driver The operator manually performs the shift. [0004] However, in an automatic manual transm...
