Intelligent Gear Shifting

For automated manual transmissions, the clutch is opened by an electromechanical clutch actuator. After the clutch is opened, the shift operations within the gearbox are taken over by an electromechanical transmission actuator. These two actuators are controlled by an electronic control unit. ZF is a single-source supplier and integrator for all the components including the transmission control unit and software.


  • Full driving comfort – no clutch actuation, no shifting
  • Prevents error during shifting
  • Lower cost and weight, smaller space claim than automatic transmissions
  • Allows manual shifting and thus individual driving styles
  • Separate programs for sportive driving, bad weather conditions or slippery or icy road conditions and trailer use
  • Reduced fuel consumption due to electronically optimized shift points and high mechanical efficiency
