ELECTROHYDRAULIC CONTROL SYSTEM FOR CONTROLLING GEARSPEED CHANGES IN PARTIALLY OR FULLY AUTOMATIC TRANSMISSIONS OF VEHICLES

摘要

A control unit has a signal input from at least one sensor and a signal output for electrically actuating at feast one valve in order to hydraulical ly activate a gear-changing element. An emergency gear change slide can switch off the electrical actuation of the valves so that hydraulic modulati on can be carried out.
