IAV in cooperation with the University of Chemnitz has developed a software package suited for transmission system engineers. The Transmission Synthesis program asks questions about transverse or longitudinal; planetary automatic, dual-clutch, or hybrid; the number of gears desired; the overall ratio spread; and the required shift elements. If hybrid, questions address the required level of regenerative braking and accelerative boosting as well as the necessity of a geared neutral. With this type of information, the program can quickly calculate and evaluate all permutations for the optimum layout of the geartrain with the least number of torque-transfer components, the most simple shift logic, and the optimum energy-transfer efficiencies obtainable with the resulting transmission architecture design. According to IAV, Transmission Synthesis saves users time, complexity, and cost on transmission development.
