DISPOSITIVO ELECTRONICO PARA EL MANDO DE LOS CAMBIOS DE VE- LOCIDADES EN UNA TRANSMISION AUTOMATICA PARA AUTOMOVILES

摘要

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.
