Regensburg, Nuremberg, Germany. December 15, 2020. The electrification of the drive system is the most important technological pioneer for clean, locally emission-free and highly efficient mobility. In addition to battery-powered electric vehicles, electrification also enables hybrids. In hybrid drive trains, the electric drive system works in a close team together with the combustion engine, offering major global benefits in reducing the CO₂ fleet emissions of a manufacturer.

Similar to the new full hybrid from Renault, where an electrical actuator module from Vitesco Technologies now takes control of the gear changes in the automatic transmission. Renault has integrated the actuator module in its E-Tech platform, which is used for example in the Clio, but also in the Mégane, Arkana or Captur.
 
For Vitesco Technologies, a leading international manufacturer of modern drive technologies and electrification solutions, this means implementing a new technology at large series production level: the automatic transmission for the full hybrid Clio E-Tech is the first dedicated hybrid transmission used by Renault in Europe. With this new form of electrification, a considerable simplification of the mechanical components in the transmission means that it will be possible to offer the full hybrid at the price level of a diesel vehicle with automatic transmission. As a result, the actuator module for transmission electrification is helping to make hybrid vehicles more attractive for the buyer and allowing better utilization of the CO₂ savings of hybrid technology. The order includes a three-digit million Euro amount throughout the entire term.

Mechatronic Solution for the Hybrid Market

Vitesco Technologies has been successfully developing electronics for automatic transmissions for decades. The company commands a leading global position in the manufacture of transmission control units. The new actuator module is the result of extensive competence in the field of control technology, expertise in actuators and an outstanding knowledge of electrification. Two electric motors delivering 100 W of power initiate the gear shifts. The dedicated hybrid transmission in the Clio E-Tech does not feature a friction clutch and so gear shifts are initiated via a claw coupling, which reduces friction losses and further increases the efficiency of the drive while reducing the installation space required. A front-transverse installation will also be possible in more compact vehicles as a result. The module uses more cost-effective direct current motors, weighs less than 1 kg, and therefore sets a major benchmark in this new market.
