DEVICE AND METHOD FOR CONTROLLING A DUAL-CLUTCH TRANSMISSION

摘要

The invention relates to a device and method for controlling a dual-clutch transmission in a vehicle, comprising a main computer (µC) for controlling the normal operation of the vehicle and a monitoring unit (WD) for monitoring the main computer (µC), wherein said monitoring unit activates a secondary control unit (SSU) in order to trigger emergency operation under certain conditions, wherein the main computer (µC), the monitoring unit (WD), and the secondary control unit (SSU) are arranged on a common circuit carrier (ST), and the secondary control unit (SSU) has an analog controller (RV1) for controlling a proportional valve (V1) and an analog controller (RM1) for controlling a hydraulic pump (M), and wherein in the emergency operation a first hydraulic clutch (K1), which is designed as normally closed, is controlled by the secondary control unit (SSU) by means of the controllers (RV1) and (RM1).
