DEVICE AND METHOD FOR REGULATING A DUAL-CLUTCH TRANSMISSION FOR ACHIEVING A SAFE STATE |
摘要 |
A device and method for regulating a hydraulically or electromechanically actuated dual-clutch transmission in a motor vehicle. A main computer selects a separate hardware unit in the emergency mode. A monitoring unit monitors the main computer and also selects the separate hardware unit in the emergency mode. At least one clutch is closed by spring force when in a depressurised state. A control unit controls a clutch actuator for actuating the clutch or for controlling a transmission actuator for providing different speeds of the dual-clutch transmission. In case of error, the safe state of an open drivetrain can be achieved by the separate hardware unit by the first control unit selecting the clutch actuator and the clutch actuator opening the at least one normally closed clutch, or by the second control unit selecting the hydraulic transmission actuator and the hydraulic transmission actuator placing the dual-clutch transmission in the neutral position. |
