Abstract

A hybrid vehicle drive control apparatus including an electric generator mechanically connected to an engine so as to have a differential rotation with respect to the engine, a generator brake for mechanically stopping a rotation of the generator and a controller that gradually decreases a generator torque while engaging the generator brake.

Claims (8)

1. A hybrid vehicle drive control apparatus, comprising:

an electric generator mechanically connected to an engine so as to have a differential rotation with respect to the engine;

a generator brake for mechanically stopping a rotation of the generator; and

a controller that gradually decreases a generator torque while engaging the generator brake, wherein upon a generator brake engagement request, the controller sets a target generator rotation speed at zero and performs a rotation speed control of the generator.

2. The hybrid vehicle drive control apparatus according to claim 1 , wherein the controller gradually decreases the generator torque after an elapse of a predetermined time following engagement of the generator brake.

3. The hybrid vehicle drive control apparatus according to claim 1 , wherein the controller gradually decreases the generator torque by performing a rotation speed control of the generator.

4. The hybrid vehicle drive control apparatus according to claim 1 , wherein the controller gradually decreases the generator torque by gradually decreasing an integral component that occurs after a proportional component reaches.

5. The hybrid vehicle drive control apparatus according to claim 1 , wherein the controller gradually decreases the generator torque by performing a torque control of the generator.
