ABSTRACT:
A method and control system for a transmission in communication with an engine includes a pedal input interpreter module determining a power demand signal from a pedal position and a vehicle speed. The system also includes a real time gear selection module determining an engine speed of each gear in response to the vehicle speed and power demand signal, determining an engine torque of each gear in response to the vehicle speed and power demand signal, determining a transmission component speed of each gear in response to the vehicle speed and power demand signal and determining a gear selection for the transmission from the power demand signal, the engine speed, the engine torque, and the transmission component speed. The system may also use the cost signal of each gear and penalty signal of each gear for determining the gear selection.
