    摘要: A system for operating a dual clutch transmission, including launch/creep controller, shift logic, and a clutch control assembly. The shift logic is configured to intercept a torque command including a target clutch torque from the launch/creep controller as it transmits the target clutch torque to the clutch assembly. The shift logic engages a preparation phase that increases torque on an on-coming clutch to a prefill torque. The shift logic then engages a torque phase that transfers torque between the off-going clutch and the on-coming clutch by simultaneously decreasing the off-going clutch torque and increasing the on-coming clutch torque. The off-going clutch and the on-coming clutch remain in a slipping state that maintains the target clutch torque during the transfer.

    摘要: A method for controlling a clutch which pertains to a vehicle and which is operated by means of a vehicle control system. The vehicle is provided with an engine, and a driver of the vehicle requests propulsive force from the engine. A first propulsive force requested by the driver and transmitted via a clutch involves determining whether the clutch slips while transmitting the first propulsive force. When the clutch slips during transmission of the first propulsive force, the propulsive force transmitted by the clutch increases. The invention relates also to a system and a vehicle.

    摘要: A first torque determining unit determines a value of a torque input to a transmission on the basis of a load acting on a start clutch (12), and a second torque determining unit determines a value of a torque input to the transmission on the basis of a manipulated amount of an accelerator pedal. After the accelerator pedal is manipulated while the start clutch (12) is in a released state, as long as the torque determined by the first torque determining unit (31a1) is less than the torque determined by the second torque determining unit (31a2), the torque input to the transmission is limited to the torque determined by the first torque determining unit (31a1).

    摘要: A hydraulic system in motor vehicles with at least one hydraulically actuated clutch, which entails minimized control complexity for supplying the clutch with hydraulic oil and which takes up less structural space. These characteristics are achieved essentially in that the pressure control of the hydraulically actuated clutch is effected directly and exclusively by an electrically driven and electronically controlled oil pump.
