1. A hybrid vehicle comprising:
- a first source of energy having a state of charge;
an induction motor which is coupled to said first source of energy;
an internal combustion engine which is selectively coupled to said induction motor;
a differential assembly which is coupled to said internal combustion assembly and to said induction motor;
a power take off assembly which is coupled to said induction motor; and
a controller which is coupled to said first source of energy, to said induction motor, to said internal combustion engine, and to said power take off assembly, wherein said controller monitors said state of charge of said first source of energy and when said monitored state of charge falls below a certain amount said controller causes said internal combustion engine to provide energy to said first source of energy, wherein said controller further allows both of said internal combustion engine and said induction motor to provide torque to said differential assembly as said power take off assembly is being operated only by said induction motor.

Abstract
A hybrid vehicle 10 including a power take off assembly 20 which is selectively and solely operated by the cooperative combination of a battery 22 and a motor 16 with the amount of electrical charge which is resident within the battery 22 is depleted by a certain amount. Upon such depletion, the internal combustion engine 12 is activated to provide electrical charge to the battery 22.

8. A power take off assembly for use within a hybrid vehicle of the type having a first source of energy, a second energy source, and a differential assembly, said power take off assembly comprising:
-
a power take off portion; and
a controller which is coupled to said first and second energy sources and which selectively causes said power take off portion to be solely operated by said first energy source while allowing said second energy source to be operated only when a certain amount of energy has been depleted from said first energy source, while concomitantly allowing both of said first and said second energy sources to provide torque to said differential assembly as said power take off portion is being operated by only said first energy source. - View Dependent Claims (9, 10, 11, 12, 13)
