ABSTRACT:
In one embodiment, a hybrid propulsion system for a vehicle is provided. The system comprises at least one drive wheel; a first motor coupled to the drive wheel, said first motor configured to selectively generate electrical energy from kinetic energy received at the drive wheel; a second motor configured to selectively generate electrical energy from kinetic energy received at the drive wheel; a transmission including a first end coupled to the first motor and a second end coupled to the second motor; and a control system configured to vary a level of electrical energy generated by the first motor relative to the second motor in response to a thermal condition of at least one of said first and second motors to provide vehicle braking.
