Abstract:
1. A drive control apparatus for a hybrid vehicle, comprising: a first motor coupled to a rotational shaft of an engine; a first drive wheel for receiving drive power from said rotational shaft through first clutches; a second motor; a second drive wheel for receiving drive power from said second motor; a first battery for supplying electric power to said first motor and said second motor; and a controller for controlling said first motor, said second motor, said first clutches, and said engine; wherein said controller controls an electric vehicle mode in which said first clutches are disengaged, the supply of fuel to said engine is stopped, and said second motor drives said second drive wheel to propel the hybrid vehicle, and said electric vehicle mode is at least divided into a first propulsion mode and a second propulsion mode; said first propulsion mode is a mode in which said first motor is de-energized; and said second propulsion mode is a mode in which a load imposed on said second motor is greater than in said first propulsion mode, and said first motor is supplied with electric power to rotate said rotational shaft at a predetermined speed.
