Control of engine torque for traction and stability control events for a hybrid powertrain system

摘要

An internal combustion engine (14) is mechanically coupled to a hybrid transmission (10) to transmit mechanical power to an output member (64). A method for controlling the internal combustion engine (14) includes determining an accelerator output torque request based upon an operator input to the accelerator pedal, and determining an axle torque response type. A preferred input torque from the engine (14) to the hybrid transmission (10) is determined based upon the accelerator output torque request. An allowable range of input torque from the engine (14) which can be reacted with the hybrid transmission (10) is determined based upon the accelerator output torque request and the axle torque response type. The engine (14) is controlled to meet the preferred input torque when the preferred input torque is within the allowable range of input torque from the engine (14). The engine (14) is controlled within the allowable range of input torque from the engine (14) when the preferred input torque is outside the allowable range of input torques from the engine (14).
