Abstract
An electronic governor receiving two signals, one corresponding to the load on the motor and the other to the speed of the vehicle comprises two time-interval comparators controlled by two switches corresponding to the manual control imposing transmission ratios and by a retrocontact switch. The output signals of the governor supplying orders for speed changes feed a sequential commutation device which controls two electrically actuated valves controlling the gear box with time delays and for transitory changes.
