ABSTRACT:
This control device for automatic change-speed transmission mechanism of motor road vehicles has a control keyboard of which the keys control the energization of switches cooperating with cam faces formed on an axially movable detector shaft the translation of which is controlled by means of a rotary cam rigid with the selector shaft of the change-speed mechanism, this cam comprising an integral radial arm responsive to a double-acting pneumatic cylinder responsive in turn to a pair of solenoid valves adapted to be energized for moving the piston of the pneumatic cylinder in one or the other direction as a function of the specific key depressed by the driver in order to provide the desired range of speed ratios, or the neutral position, or the reverse gear.
