Hybrid electric vehicle
First Claim
Patent Images
1. A hybrid vehicle comprising:
- an internal combustion engine;
a second source of energy having a certain amount of charge;
a controller which is coupled to said second source of energy; and
a power take off portion which is coupled to said controller, said controller containing a certain stored value and allowing said power take off portion to be activated only if said certain amount of charge is greater than said certain stored value and deactivating said power take off portion when said certain amount of charge falls below said certain stored value.

7. A power take off assembly for use within a hybrid vehicle of the type having an internal combustion engine and a second source of energy, said power take off assembly comprising:
-
a power take off portion;
a clutch assembly which is coupled to said power take off portion and to said second source of energy; and
a controller which is coupled to said power take off portion, to said clutch assembly, and to said second source of energy, which selectively deactivates said internal combustion engine while allowing said power take off portion to be solely operated by said second source of energy, and which, when the amount of charge from said second source of energy falls below a certain stored value, said controller deactivates said power take off portion and provides a warning signal. - View Dependent Claims (8, 9, 10, 11, 12)

13. A method to operate a power take off assembly comprising the steps of selectively coupling the power take off assembly to a source of energy;
- creating and storing a certain value;
selectively deactivating an internal combustion engine;
monitoring the state of charge of said source of energy; and
allowing said power take off portion to be activated by said source of energy only if said state of charge of said source of energy is greater than said certain stored value and deactivating said power take off portion and providing a warning signal when said source of energy falls below said certain stored value. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
