Transmission control device for driving device for hybrid vehicle

Abstract

The present invention provides a gear shift control device for a hybrid vehicle driving device capable of eliminating a sense of failure during a gear shift operation and reducing a gear shift shock. The gear change control device takes a drive device for a hybrid vehicle having an engine, an automatic transmission, a clutch, and a motor generator as a control object, and has the following means: a means for instructing a driver's requested torque determined by an operation amount of an accelerator unit; A unit that reduces the engine torque and generates the motor torque when the shift condition is established, and makes the clutch in the disengaged state, and returns the clutch to the connected state after switching the gear train, reduces the motor torque and increases the engine torque; after switching the gear train so that A means for obtaining the motor torque by subtracting the clutch torque from the driver request torque while the speed difference obtained by subtracting the transmission input speed from the engine speed exceeds a first predetermined value after the gear ratio is increased.

Description

Technical field [0001] The present invention relates to a transmission control device for a hybrid vehicle driving device having an engine and a motor as driving sources for traveling. Background technique [0002] In recent years, hybrid vehicles with engines and motors as driving sources for traveling have rapidly spread, and various types of drive devices have been put into practical use. For example, it has a structure in which an input shaft of an automatic transmission is connected to a power output shaft of an engine via a clutch, and a motor is connected between an output shaft of the automatic transmission and driving wheels. In this structure, a motor generator that also has a power generation function is often used as the motor without a separate generator. In addition, as an automatic transmission, for example, an automated manual transmission (AMT) can be realized by adding an actuator to a manual transmission that selectively engages a pair of gears in a plurality ...

Problems solved by technology

As a result, when motor torque is generated to compensate for the engine torque obtained from the torque characteristic map, the actual drive torque transmitted to the drive wheels exceeds the magnitude of the inertia torque, resulting in a shift shock.
