Abstract:
Methods and a system are provided for shaping a torque profile for a motor of a hybrid vehicle. In one example, the method includes during a vehicle launch, an off condition of an engine, and upon receiving an engine start request, predicting a time of engine engagement, predicting a driver requested torque at the engine engagement; and reducing the driver requested torque until the predicted time of engine engagement based on the predicted driver requested torque at the engine engagement. The predicting of at least one of the time of engine engagement and the driver requested torque at the engine engagement may be based on a current position of an accelerator pedal and a driver profile. The method may further include controlling motor torque profile based on the reduced driver request torque.
