摘要:
In a method for referencing the position of an actuating element of a functional unit, in particular of a clutch in the drivetrain of a vehicle, the attainment of a reference position of the actuating element is assessed for plausibility in that it is checked whether a variable which can be applied to the actuating element varies in a predetermined way in a predetermined spacing of the position of the actuating element from the reference position.
摘要:
A method for checking the plausibility of an actuation position of a clutch of a double-clutch transmission operated by an actuator, including the following steps: disengaging the clutch assigned to the currently active old subtransmission and simultaneously engaging the clutch assigned to the other subtransmission to shift from the gear selected in the old subtransmission to a gear selected in the other, new subtransmission; deselecting the gear selected in the old subtransmission still during the overlapping operation of the clutches or immediately thereafter; detecting the difference between the speed of rotation of a drive shaft of the double-clutch transmission driven by a drive motor and the speed of rotation of the input shaft of the old subtransmission; and evaluating the state of the clutch assigned to the old subtransmission as disengaged when the difference in speeds of rotation exceeds a predetermined value within a predetermined time after deselection of the gear.
摘要:
A method for controlling an automated gearbox of a motor vehicle. An electronic control unit controls pre-determined functionalities, and especially pre-determined functionalities of the automated gearbox. Functional software runs on a main processor of the control unit, controlling pre-determined functionalities of the motor vehicle and especially the automated gearbox. An electronic safety system is able to determine safety-critical operating conditions of the motor vehicle in advance, and includes a redundant processor and monitoring software.
摘要:
A method for controlling a transmission of a vehicle, especially an automated transmission and/or an automated clutch. A starting characteristic curve is used to adjust a nominal torque of the clutch, the characteristic curve is modified in order to adapt to different operating states of the vehicle, in such a way that the desire of the driver is taken into account when the vehicle is brought into motion.
