Hybrid vehicle drive control apparatus, hybrid vehicle drive control method, and program thereof
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.
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.
