Abstract
The flow rate of intake air in an engine, engine speed, and automobile speed are detected. The speed-change ratio of a transmission is determined and adjusted in response to a signal which is proportional to the detected intake air flow rate and inversely proportional to the detected engine speed, and in response to the detected automobile speed.
