Abstract
A driver request module determines a driver torque request based on an accelerator pedal position, a first difference between a target engine speed and a transmission input speed, and a second difference between the transmission input speed and a measured engine speed. A request generating module generates first and second torque requests based on the driver torque request. An engine speed control module generates third and fourth torque requests based on a target engine speed and the first and second differences. Based on a mode signal: a first selection module sets a fifth torque request to one of the first and third torque requests; and a second selection module sets a sixth torque request to one of the second and fourth torque requests. An adjusting module selectively adjusts an engine operating parameter based on at least one of the fifth and sixth torque requests.
