摘要:
For an electro-hydraulically controlled automatic transmission (2) in which shifts are performed by overlapping, a method is proposed for increasing the spontaneity, in which a variable hold time is introduced for a disengaging clutch. This variable hold time is a function of the rotational speed differential of a transmission input speed (nT) and the temperature of the hydraulic fluid (.THETA.).
摘要:
A method is proposed for increasing the spontaneity of an automatic transmission where the gear shifts are carried out as overlapping gears. Here an upshift from a first to a second reduction step is not completely terminated and a change over to a downshift is carried out when an abort criterion is detected.
摘要:
The invention relates to a method for increasing the spontaneity of automatic gear boxes with overlapping gear shifts. The overlapping gear shifts consist of three phases. Upshifting from a first gear ratio to a second gear ratio is aborted and downshifting to a first gear ratio occurs if an abort criterion is detected. The abort criterion is validated if a request for downshifting is made by the driver and detected before the third overlapping shift phase begins.

A method for increasing the spontaneity is proposed for an automatic transmission, the gear shifts of which are carried out as overlapping gear shifts. Here an upshift from a first to a second gear is not completely terminated and a change back from an upshift to the first gear is carried out when an abort criterion is detected.
摘要:
A device for determining an operating state of a bi-directionally actuated hydraulic adjusting device of a transmission shifting element, which pressurizes active surfaces of a piston. The piston is biased to opposite end positions depending on which of a first active surface or a second active surface is pressurized with high pressure. The areas of the adjusting device, which can be pressurized with the pressure at the active surfaces of the piston, are connected with one another in positions of the piston element, between the end positions, via a throttle device. One of each area can be coupled for adjustment of the piston with the high-pressure area, and the other area with the low pressure area. An additional throttle device is provided upstream of the low pressure area and a pressure measuring device is provided upstream of the additional throttle device.

A driver assistance system for assisting a driver in achieving consumption-controlled driving combines haptic and visual acknowledgment functions, particularly in the form of a drive configuration, a display concept, and/or a deceleration assistant. A modified characteristic accelerator pedal curve is utilized, and ECO tips of the interactive output of efficient driving instructions are provided.

A labeler for labeling plastic containers in the blow mold as well as to a labeling method for use of the labeler, where due to the fact that the rotating insertion device of the labeler comprises articulated anus having each rotatably supported thereon a gripper, it is possible to remove labels from stationary magazines at a comparatively low relative speed. The articulated arms are able to follow the path of the blow molds during insertion of the labels with high speed. The grippers are rotatably supported which allows an exact radial orientation of the gripper with respect to the axis of rotation of the blow wheel that continues to rotate during insertion of the labels, to thus allow a particularly accurate and reliable labeling.
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.
摘要:
A method of operating an automatic transmission of a motor vehicle, in particular a variable-speed transmission. The automatic transmission includes at least five shift elements, at least three of which are engaged in a forward and a reverse gear to transfer torque or force. When disengaging gears for shifting the automatic transmission from a forward or reverse gear to a neutral position, at least one of the at least three shift elements that are engaged in the respective forward or reverse gear is completely disengaged.
