Abstract
During shift control of a transmission mechanism, a hybrid drive device computes the amount of change in input torque (deTr) acting on the transmission mechanism and an input torque change time (t15), and controls a motor so that motor torque is changed by the amount of change in input torque (deTr), when the motor can change the amount of change in input torque (deTr), and outputs, when the motor cannot change the amount of change in input torque (deTr), an engine torque signal (Tesig1) at an engine torque change time (t14) earlier than the input torque change time (t15) at which drive power of the motor is changed when the motor can change the amount of change in input torque (deTr).
Claims20
A hybrid drive device comprising:
- a transmission mechanism that has an input member drive-coupled to an engine and an output member drive-coupled to wheels, and performs shift control for changing a transmission gear ratio between the input member and the output member;
- a rotating electrical machine drive-coupled to the transmission mechanism;
- and
- a control part that, during shift control of the transmission mechanism, computes a change time and an amount of change by which drive power acting on the transmission mechanism is changed, controls the rotating electrical machine so that drive power of the rotating electrical machine is changed by the amount of change, when the rotating electrical machine can change drive power by the amount of change, and outputs an engine instruction signal for changing drive power to the engine, when the rotating electrical machine cannot change drive power by the amount of change,
- wherein
- when the rotating electrical machine cannot change drive power by the amount of change, the control part outputs the engine instruction signal to the engine at a pre-change time earlier than a change time at which drive power of the rotating electrical machine is changed when the rotating electrical machine can change drive power by the amount of change.
