DPS6 Dual Clutch System
     Transmission Controls Innovations
Ford Controls and Software Development Engineers have developed novel
  control strategies to maximize customer satisfaction with the Powershift

• 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

• 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.
       Transmission 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.
 DPS6 Transmission – key points
- All NEW, segment exclusive DCT technology.
– Enables Fiesta to achieve outstanding fuel
– 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
