Continuing the project launched in 2006 to develop a new family of transmissions, researchers concentrated on designing and constructing the actuation and control system of the new DDCT. This transmission is able to achieve a level of gear shifting comfort comparable to that of traditional automatic transmissions (AT), but with a level of efficiency on a par with that of automated manual transmissions (AMT), usually 10% higher than AT. The transmission actuation system is electro-hydraulic to ensure fast gear shifting, compactness and energy savings. The transmission control system is integrated with that of the engine to guarantee coordination of the power delivered with the transmission of the clutches during pickup manoeuvres, gear shifts and driving in automatic mode. The system actually comprises two automated transmissions, one with even gears and the other with odd gears, arranged in parallel; the gear is inserted in one of the two, while the other continues drive with the other gear. The gear change is obtained by modulating the corresponding clutches in order to guarantee drive during the entire manoeuvre. The clutches are “dry” to minimise the impact on the vehicle and to maximise the efficiency of the entire system.
