The transmission is shifted from a current gear ratio to the target gear ratio if the target and current gear ratios differ. By selecting the target gear ratio, vehicle fuel efficiency is improved, while keeping the vehicle under constant prime mover braking or continuous prime mover control. | 09-30-2010 |
