1. A method of controlling a vehicle power usage split between engine-supplied power and motor generator-supplied power for a hybrid electric vehicle, the method comprising:
receiving first data indicating a current engine-supplied power to a transmission of the hybrid electric vehicle;
receiving second data indicating a current motor generator-supplied power to the hybrid electric vehicle transmission;
determining a current battery state of charge;
determining, based on the received first and second data, an impact of at least one of current environmental conditions and road conditions on an amount of the current engine-supplied power and an amount of the current motor generator-supplied power; and
controlling a power usage split of the hybrid electric vehicle based on:
the current engine-supplied power amount relative to the at least one of the current environmental conditions and road conditions impact;
the current motor generator-supplied power amount relative to the at least one of the current environmental conditions and road conditions impact; and
the current battery state of charge.
