Abstract
An automatic transmission is changed from the highest gear ratio to the next lower gear ratio upon depressing the brake pedal after the accelerator has been released to cause the automotive vehicle to begin a coasting operation as long as the engine speed is higher than a predetermined engine speed. As a result the engine speed increases, resulting in an increase in the time period when the engine speed remains above the predetermined engine speed to enhance the time period of the operation of fuel cut means, thereby improving fuel economy.
