Honda developed 9-speed Dual Clutch Transmission for 2nd-generation NSX. This transmission had required compact layout , acceleration performance and high shift response. The parallel multi-shaft structure of twin mainshaft contribute to compact layout. High torque capacity clutch and high strength material parts were adopted for transmitting high torque of 550Nm. And , two kinds of oil were applied in clutch room and gear room with optimized lubrication and cooling system. In addition , optimum gear ratio and high shift response enabled driving of super sports car , quiet cruising at high speeds was realized by 9-speed.

Thanks to sensors, machine vision and connectivity (V2X, cloud, etc.) vehicles have an increasingly better knowledge about future driving situations, such as traffic, road slope, etc. That information can be used to better control the powertrain, whether for fuel economy, drivability or durability. With automation, the added additional degree of freedom (longitudinal speed) will present further opportunities for powertrain design and control optimization. In this talk we will present simulation frameworks that model powertrain operations during connected and automated driving.

General Motors Global Propulsion Systems’ first nine-speed automatic transmission makes its debut in the 2017 Chevrolet Malibu, advancing a legacy of multispeed transmissions designed to optimize efficiency, performance and refinement. The Hydra-Matic 9T50 nine-speed is paired with an Ecotec 2.0L Turbo engine in the Malibu, contributing to an EPA estimated 33 mpg highway, a three-percent increase over the 2016 model eight-speed automatic. The 9T50 has a wider 7.6:1 overall ratio, which is the ratio between the first gear ratio and the top gear ratio, - compared to the six-speed’s 6.0:1 ratio. The 9T50 is fitted with a “deep” 4.69 first gear ratio for excellent off-the-line acceleration and a “tall” 0.62 top gear ratio for low-rpm highway cruising. That balance optimizes acceleration and fuel economy while reducing engine noise during cruising. With nine available forward ratios, the step size between the gears is reduced providing smooth, precise upshifts and excellent refinement.
