Sicherheitssystem für ein Automatgetriebe

摘要

The invention relates to an automatic gearbox. The electronic control instrument (12) detects outside the circuits a fault in the input values (18 to 20), the couplings and brakes (A to F). When the fault is present for an extended period, the electronic control instrument (13) detects a symptom and switches to a replacement gear thereby ensuring maximum drivability without the introduction of a diagnostic operation.
