A powertrain with a conventional automatic gearbox is a complex dynamic system. The properties of the engine, torque converter, gears and tyres vary as functions of speed and load. The variation is especially significant for the efficiency of the torque converter. The target for the designer is to find the best compromise between emissions, driveability, fuel economy and performance so that both legislation and company requirements are satisfied. This paper mainly concerns fuel consumption and performance, and a useful method for designing optimum control strategies for automatic gearboxes.
