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 least one valve in order to hydraulically activate a gear-changing element. An emergency gear change slide can switch off the electrical actuation of the valves so that hydraulic modulation can be carried out.
