A new PHV transaxle aims for the EV driving force. To achieve this, a one-way clutch is placed between the engine and power split device realizing the dual motor drive system, which enables the vehicle to be driven using two motors.
Full gear detection for manual transmissions is a necessary function for modern gearboxes, not only for driver assistance systems, such as the recommendation of the most suitable gear according to speed, it is necessary to know the current state of the transmission.

With its CVO (Controlled Valve Operation) system solution for direct injection engines, Bosch has adopted a mechatronic approach that can make a valuable contribution to legal limits for emissions. Unlike conventional open-loop controlled injection, the control unit and high-pressure injectors constitute a closed loop in this setup. The control unit detects the triggering signal for the high-pressure injectors across the entire injection process and determines the timing for opening and closing the valve needles. Thus, the control unit can calculate the actual injection quantities of each injector and make adjustments where necessary. CVO offers an innovative and cost-effective approach to engine optimization.
