Modelling of Automatic Transmission System With 12 Speed Gearbox Configuration for Passenger Car

This research describes the modelling of automatic transmission with 12-speed gearbox configuration suitable for passenger cars with front engine, rear wheel drive/all wheel drive. In this 12-speed gearbox, the gear step size was further decreased with an improvement in shift quality of gears. This design can further lead to the outstanding driver satisfaction with excellent drive feel. This model also provides jerk less travel because of its rhythmic gear shift changes.
