Abstract
Methods and systems are provided for enhancing reverse driving torque in a powersplit hybrid electric vehicle powertrain. In one example, a method may include accelerating an engine via a generator functioning as a motor, any number of times, to provide an engine braking torque that may increase a reverse driving torque to enable the vehicle to be propelled in reverse at a vehicle speed above a threshold vehicle speed. In this way, reverse gradability may be improved and customer satisfaction increased.
