Drive control apparatus for hybrid vehicle
First Claim
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.

Abstract
A rotational shaft receives drive power from an engine and a first motor, and drives front wheels through front clutches. A second motor drives rear wheels. The first motor and the second motor are supplied with electric power from a battery. A main ECU controls an electric vehicle mode in which the first clutches are disengaged, the supply of fuel to the engine is stopped, and the second motor drives the rear wheels to propel a hybrid vehicle, by dividing the electric vehicle mode into a first propulsion mode and a second propulsion mode. In the first propulsion mode, the first motor is de-energized. In the second propulsion mode, a load imposed on the second motor is greater than that of the first propulsion mode, and the first motor is supplied with electric power to rotate the rotational shaft at a predetermined speed.
