<p>PURPOSE:To operate an automobile engine with minimum fuel consumption, by setting an optimum gear changing diagram for each stage of gear changes with a manual change gear in accordance with monitored values of vehicle speed, etc, until the gear of an auxiliary change gear is shifted after the speed change. CONSTITUTION:An auxiliary change gear which can select in two stages of high and low is controlled by solenoid devices 30, 31 which selectively actuate built-in brake and clutch devices. The solenoid devices are controlled by a controller with a built-in computer 50. The computer 50 receives signals from a speed sensor 51, throttle valve sensor 52, shift position sensor 53 and clutch sensor 54, sets an optimum speed control diagram for each stage of the manual change gear until a gear change is done by the auxiliary device after shifting the speed in accordance with the monitored values, and afterwards sets the said diagram for each stage of the manual change gear.</p> |
