Engine Start/Stop systems are becoming a standard part of today's automobiles. Start/Stop with permanently engaged starter is a solution to get an excellent engine Start/Stop behavior in all driving situations. Based on results from simulation, bench tests, and vehicle measurements, this paper shows the benefits of such a system in combination with different transmissions and launch devices. Dual clutch transmissions (DCTs) have an increasing share in automatic transmissions market. They have found application in a very wide variety of vehicles and over a wide range of engine torques while providing best fuel efficiency. Excellent comfort, high-shift dynamics, and robust launch performance are the key attributes of a wet dual clutch transmission. This paper also evaluates electrified drivetrains and their influence on the vehicle launch performance and efficiency. Together, the electrification of components like the transmission hydraulic pump and the drivetrain to provide electric launch is shown as a solution for future drivetrains.
