Steuersystem fuer automatische Kraftfahrzeuguebersetzungsgetriebe

摘要

An automatic transmission mechanism for an automotive vehicle in which the transmission governing factors such as the position of the speed selecting lever, position of the accelerator pedal and the throttle valve, engine speed, vehicle speed and road grade are measured by electric means and the signals thus obtained are continuously fed into an electronic control system for evaluation of the requirements from the transmission. The electronic control system sends signals to elements converting them into hydraulic pressure which actuates friction elements to change gear ratios of the transmission.
