Abstract:
A hybrid transmission includes torque machines and an energy storage device connected thereto. Thee hybrid transmission is operative to transfer power between an input member and an output member and the torque machines. A method for controlling the hybrid transmission includes monitoring operating parameters of the hybrid transmission, monitoring an operator demand for power, determining an output torque range to the output member based upon states of the operating parameters of the hybrid transmission, constraining the output torque range to the output member based upon the operator demand for power, and determining input torque constraints to the input member based upon the constrained output torque range to the output member.
