    摘要: Disclosed are a method and an apparatus for detecting a touch point of a clutch and the method includes: maintaining a touch point of the clutch; correcting a setting value for determining a lowest value by calculating drag torque using a speed and an acceleration of a input shaft to change a detection range of the touch point; setting the lowest value of the speed of the input shaft within the changed detection range of the touch point to a reference value of the input shaft after actuating the clutch; releasing the clutch when the speed of the input shaft is more than a value acquired by adding the reference value of the input shaft and the corrected setting value for determining the lowest value; and updating the touch point as a clutch position matched to the reference value.

    摘要: A method operates a clutch release system of a vehicle having an electrically actuable clutch release unit including a sensor for detecting a position of a release piston, a control unit for controlling the release piston as a function of a detected position of a clutch actuating device, and a sensor for detecting the position of the clutch actuating device. A characteristic curve function describes a relationship between the position of the clutch actuating device and the position of the release piston. The function is taken into consideration during actuation of the clutch release system to obtain a consistent clutch release at a defined position of the clutch actuating device despite progressive wear of the clutch release system.

    摘要: Apparatus (control device) and a method for controlling a torque transmitting device such as a brake, wet clutch, dry clutch (10) during a filling and slip phase is provided, e.g. for coupling a first shaft (12) to a second shaft (14) via the wet clutch (10). A reference profile (52) for a control variable is provided, wherein the chronological progress of said control variable influences the position of a piston (22) for actuating clutch elements (16, 18), Each clutch element (16, 18) is connected to the first shaft (12) or the second shaft (14), with respect to a cylinder (20) of the wet clutch (10), and the control variable is determined during each coupling and a valve (38) for applying a pressure source to the piston (22) is operated, wherein the valve (38) is controlled during each coupling by means of a feed forward closed loop control (54) such that the control variable follows the reference profile (52). Due to the increased control quality by considering non-linear effects by means of the reference profile (52) for the feed forward closed loop control (54) at every coupling through learning, the coupling time can be shortened without increasing the risk of an uncomfortable coupling behavior.

    摘要: A clutch control device for vehicle equipped with a clutch actuator driven by a working fluid, wherein the rate of connection of the clutch is correctly controlled by using a simple means while compensating for secular changes in a flow rate control valve that controls the working fluid. To control the stroke of the clutch actuator 110, the clutch control device is provided with a single flow rate control valve 1 that controls the feed and discharge of the working fluid by using an electromagnetic solenoid. A flow rate control valve control device 9 is equipped with a learning device 91 that learns the neutral position of the flow rate control valve 1 to shut off the flow of the working fluid. At the time of learning, the learning device 91 renders the transmission to be neutral, executes the operation for increasing the stroke after the stroke is decreased, detects the rate of change in the stroke, and learns the central point at the neutral position. In controlling the stroke of the clutch, the amount of electric current to the coil 8 is adjusted based on the learned value to compensate for a change in the flow rate characteristics caused by secular change and the like.
