Abstract:
A system and method for controlling a hybrid electric vehicle powertrain having an engine defining one power source, and a traction motor and electrical storage device defining another power source include inhibiting a stopping and a starting of the engine based upon an unintended tip-out event and an unintended tip-in event, respectively. The total power demand and the available electric power are determined. The total power demand is filtered. The engine is prevented from being pulled-up or pulled-down based upon a difference between the total power demand and the filtered power demand being exceeding a threshold. However, if the difference exceeds the threshold, and if the available electric power exceeds the total power demand, then the engine is permitted to pull-up or pull-down.
