Abstract:
1. Method for controlling operation of a multi-mode transmission configured to transfer torque among an input member coupled to an internal combustion engine, torque machines and an output member in one of a plurality of fixed gear modes, continuously variable modes and Neutral, the method comprising: employing a closed-loop control scheme to determine torque commands for the torque machines in response to a desired input speed of the input member and an estimated wheel speed of a wheel of a driveline coupled to the output member; and upon detecting an abrupt change in an output speed of the output member causing lockup of the output member, employing the closed-loop control scheme to determine torque commands for the torque machines in response to the desired input speed of the input member and a monitored wheel speed of the wheel of the driveline.
