1DPS6 Powershift Transmission Game Changing Technology for Fuel Economy
2Game Changing Technology DPS6The segment exclusive 6-speed DPS6 Transmission and Powershift Technology will provide a competitive advantage through superior mechanical efficiency and performance improvement.FUEL ECONOMY / CO2PERFORMANCECONNECTED FEELPROVIDES TORQUE TO THE WHEELS 100% OF THE TIME8-10% fuel economy improvement vs. traditional 4 speed automatic
3DPS6 Transmission Torque range up to 250 Nm 6 gears – total span 5.6 Covers B and C platforms4 shaft designDual clutch system – with Dry Clutch (like M/T)Compact ~350 – 380mm long, 183mm ctr. distanceLight weight - only 73 kgElectromechanical shift actuation systemElectromechanical clutch actuation systemMAM – onboard TCMMechanical park systemElectronic range selection.No external fluid connections
4DPS6 – Key Benefits Improved fuel economy Very high mechanical efficiency vs hydraulic A/Ts.Eliminates the need for hydraulic controlsNo torque converter, no oil pump… no parasitic losses.Low viscosity transmission oil6 speed wide ratio span (5.58) allows the engine to run at optimal operating speed for both city and highway.Powertrain control innovations to maximize efficiencyMaintenance FreeFill for life trans oil - No dipstick checking requiredDual clutch is designed to last for 10 years / 150k milesCooler lines are eliminated, no oil leaks
7Transmission Controls Innovations Ford Controls and Software Development Engineers have developed novel control strategies to maximize customer satisfaction with the Powershift transmission:Neutral Idle – the clutches will disengage when the brakes are applied. This function Increases fuel economy, improves coasting downshifts and improves clutch robustness.Precise Clutch Control – Micro Slip for NVH Improvements Provides torsional damping through clutch slip. Improves NVH at low engine speeds and enables lower lugging limit for improved fuel economy.Torque Hole Filling – Provides smooth torque transfer during up shifts through precise coordination of engine torque delivery during the shift.Tip In/Back Out Logic – All new algorithms developed to provide smooth torque transitions to handle rapid changes of driver pedal input.
8Transmission Controls Innovations Slow Speed Driving (Creep) w/ Integrated Brake Pressure – Provides typical creep function that drivers expect out of an automatic transmission (torque as a function of brake pressure). Provides customer comfort and control for low speed/parking lot drivability.Hill Mode – Launch Assist – Integration of the brake control function with the transmission strategy to provide improved drivability on hills. Brakes will hold brake pressure until the engine delivers enough torque to move the car up the hill. This feature prevents vehicle roll back on a grade. This provides improved driving confidence/comfort/safety while also providing clutch robustness.Ford Grade Assist – Implementation of Ford Grade Assist algorithm for improved driveability/control on hilly terrain. Driver selectable function through button on shifter.
9DPS6 Transmission – key points - All NEW, segment exclusive DCT technology.Enables Fiesta to achieve outstanding fuel economy.Provides the connected feel of a manual transmission, while also providing smooth gear shifts and the convenience of conventional automatic transmission.Delivers new functionality to the customer through the use of electro-mechanical control systems and Ford developed controls innovations.
