  • METHOD AND APPARATUS TO DETECT A MODE-GEAR MISMATCH DURING OPERATION OF AN ELECTRO-MECHANICAL TRANSMISSION
    Publication number: 20120035019
    Abstract: A vehicular powertrain includes an electro-mechanical transmission mechanically-operatively coupled to an internal combustion engine. A method for operating the powertrain includes monitoring operator inputs, monitoring a transmission output, and terminating an engine operating mode when a time-rate change in the transmission output exceeds a threshold absent a change in the monitored operator inputs.
    Type: Application
