CTI Mag: Further CO2 savings thanks to Electric Transmission Oil Pumps
Conventional, mechanically driven oil pumps must provide the power required under maximum load at each speed in the transmission. In general, under real operating conditions these pumps waste not only valuable energy, but also material and space. Electric oil pumps, on the other hand, provide the power which is actually required at the load points. Further efficiency gains in the transmission are thus possible.

CTI Mag: Hydraulic Accumulator in Transmission Controls
Dual clutch transmissions offering disruption-free traction are in the portfolio of all well-known auto manufacturers. The hydraulic accumulator is the ideal solution to ensure that hydraulic actuations are as efficient as possible even at peak demand. Independent investigations have shown that the hydraulic accumulator makes it possible to gear components, such as the hydraulic pump for actuators, to reduced fuel consumption. This saves energy and reduces CO2 emissions. The hydraulic accumulator needs only about a sixth of energy of a conventional constant pump. Thus, the CO2 emission is reduced by up to 4 g/km.

CTI Mag: Dynamic Torque sensing for Future Power Train Control
More stringent world-wide government regulations addressing the reduction of poor air quality across many cities and noise pollution whilst increasing road safety are driving the Automotive Industry manufacturers to focus R&D efforts on more efficient and accurate overall powertrain control.

CTI Mag: What ECU Concept is the right one for your Project?
Ing. Philipp Neumann MSc, MELECS EWS GmbH
What options are possible?
When you design an ECU, the most important thing is to never lose the clear vision of what the customer requires and what options apply to those requirements. Will a standard ECU be enough, or do you need to go all the way and opt for a smart ECU system with an integrated motor?
