As the number of peripheral components grows to accommodate ever increasing demands for functionality and performance in transmission applications, the integration of different technologies to obtain the best solution in terms of performance to a given application is considered to be the essence of system design. The behaviour of a mechatronic system is determined by the interdependencies of its components. Therefore, the design and development of mechatronic systems in transmission applications require an integral approach to deal with sub-systems and sub-processes of multiple domains, i.e. hydraulic, mechanical, magnetic, and electrical. The integration of mechatronic systems can be performed by components (hardware-integration) and by information processing (software-integration). The information processing consists of low-level and high-level feedback control, supervision and diagnosis, and general process management.

The shift quality of a transmission is one of the major factors influencing ride comfort and drivability of a vehicle. This shift quality is a function of both the transmission hardware and the software in the electronic control unit which includes both algorithms and calibrations. Because of this, the transmissions are tested in unison with the electronic control units on powertrain dynos. This is also an opportunity for the engineers to figure out preliminary calibrations for optimal performance/ride quality. The next step is to install the transmission in a prototype vehicle and have the test drivers get a 'feel' for the upshifts and downshifts under various driving conditions. This process is somewhat subjective and requires extensive testing on prototype vehicles which may not be ready when the transmission is. The approach we are presenting couples a powertrain dyno with a high-fidelity vehicle dynamics model running in real time. This enables the users to: 1.

Torque converters are an integral part of automatic transmissions and have a significant effect on vehicle performance and fuel economy and, therefore, on emissions. Modern transmission design with increasing number of gears requires the converter to fit in smaller space with comparable or improved functionality. One of the important components in the torque converter is the lockup clutch. It allows a direct connection between engine and transmission for fuel economy optimization. The clutch is designed to have enough capacity to transmit engine torque to the transmission without energy loss. At higher engine speeds clutch capacity starts to diminish. This phenomenon has been studied and analyzed using Computation Fluid Dynamics (CFD). New computational methods have been applied and determined the root cause. Extensive component geometry optimization has been conducted in order to find a solution without impacting the transmission/converter space claim.

To select transmission with flexible feature which makes itself applicable to world wide market is increasingly required instead of changing transmission types region by region concerning the market situation. Jatco has been encouraging the evolution and prevalence of CVT which essentially has high flexibility for realizing good fuel economy, and expanded its worldwide penetration. In this presentation , our new technologies of steel belt for Jatco CVT8 will be introduced. Jatco has developed completely new 28-mm belt. This belt has been developed for the Jatco CVT8 to obtain higher efficiency, a smaller size and a lighter weight. In the presentation, the key technology of the new 28-mm steel belt will be explained. The key technologies include specific shape, geometry and material.

Introducing a new type of cold clamping as an application for mounting a bracket to a frame. This cold metal deformation process is recently introduced by KPIT & DAF Engineering (for DAF- Trucks, a Commercial Vehicle Manufacturer from the PACCAR GROUP} The current engineering of tubular mounting brackets has improved the product characteristics by eliminating critical welding process and introducing the new simple and robust cold clamping technology. This design model enables lower life-cycle cost consistent product with required performance, reliability & quality. Use of this bracket has lot of advantages over conventional welding process like simplified manufacturing process with an improved manufacturing tolerances. It eliminate the cost on sheet metal flattening and re-straightening metal tubes, improved Design for Assembly (DFA), easy to mount on vehicle without using any special tools and minimal assembly tolerances of the complete end assembly (less deviation).

The control of the flow over aerodynamic shapes in order to achieve performance enhancements, such as improved aircraft maneuverability, has been a lively area of research for last two decades. Active flow control can produce significant performance improvement when combined in a closed-loop control system. Synthetic jet actuators (SJAs) are devices able to interact actively with the flow around a hosting structure by providing ejection and suction of fluid from an orifice. The research presented in this paper concerns the implementation of zero-net-mass-flux SJAs airflow control system on a NACA0015, low aspect ratio (LAR) wing section prototype developed by Clarkson University under the Advancement of Intelligent Aerospace Systems (AIAS) AFOSR Grant FA9550-09-1-0051. Two arrays of custom made SJAs, installed in the proximity of the leading edge and flap of the wing section, make up the actuation system.
