Patent ID: 7766109

Claim:
A hybrid powertrain for use in a vehicle including an engine coupled to a motor, wherein the motor includes a plurality of gears, and the engine includes a plurality of cylinders, the hybrid powertrain comprising: a battery pack configured to supply power to the motor; a temperature sensor in communication with the battery pack and configured to sense a temperature of the battery pack; an electrically variable transmission configured to damp vibrations from the engine; an engine control module configured to provide commands for supplying fuel to (i) all of the plurality of cylinders, (ii) a portion of the plurality of cylinders, or (iii) none of the plurality of cylinders; a system controller configured to provide a braking command to a brake pad; and a hybrid control module configured to communicate with the temperature sensor to determine whether the sensed temperature of the battery pack is above or below a first threshold and to communicate with the electrically variable transmission such that when the determination is made that the temperature of the battery pack is below the first threshold, the hybrid control module provides commands to the electrically variable transmission to limit a gear shift command between a first mode or a second mode, supplies a command to the engine control module to command the plurality of fuel injectors to inject fuel into all of the cylinders of the plurality of cylinders, and supplies commands to the system controller to provide a braking command to the brake pad when the engine control module is supplying a command to the fuel injectors to inject fuel into all of the cylinders of the plurality of cylinders.
