Abstract: A method and device for operating a powertrain of a motor vehicle are provided, wherein the powertrain includes an internal combustion engine, a transmission and a friction clutch arranged there between in order to control a power flow between the internal combustion engine and the transmission. The method includes the steps of detecting clutch judder, analysing clutch judder, and determining a type of clutch judder. Based on determined type of clutch judder the method further includes selecting a udder countermeasure from a number of predetermined judder countermeasures and executing selected judder countermeasure. Detected clutch judder can be taken care of in an efficient way and future clutch judder may be prevented.

Abstract: A sleeve stroke SSt of a specific sleeve is gradually increased from “0” (after t1) in a state in which a vehicle is stopped, a transmission is in a neutral state (all sleeve strokes SSt=0 (original position)), a clutch is in a disengaged state (clutch stroke CSt=0 (original position)), and an engine is operating (engine rotational speed NE>0). Upon determination that the sleeve stroke SSt has reached a predetermined value A, at which synchronization operation of a corresponding synchronization mechanism is performed, the sleeve stroke SSt is fixed to the predetermined value A, and an operation of increasing the clutch stroke CSt from “0” in a press engagement direction is started (time t2). An engagement start point CStlearn of the clutch is obtained based on a change in the rotational speed Ni of an input shaft Ai of the transmission after that (time t3).

Abstract: A propulsion system controller for a vehicle that includes a prime mover operable for generating an input torque on an input shaft, and a transmission connected to the prime mover that is configured to receive the input torque from the input shaft and produce an output torque on an output shaft. The controller is programmed to generate a torque phase ratio, rationalize the generated torque phase ratio, and submit a torque request to the prime mover that is based upon a desired output torque divided by the rationalized torque phase ratio.

Abstract: A hydraulic control device for an automatic transmission includes a shut-off valve arranged between a first pressure adjusting device and a respective shifting element cylinder of a plurality of shifting elements. In the first shifting position of the shut-off valve, the first pressure adjusting device is hydraulically connected to the respective shifting element cylinder through the shut-off valve. In the second shifting position of the shut-off valve, the shifting element cylinder is sealed by the shut-off valve relative to the first pressure adjusting device. The shut-off valve is an releasable check valve. The releasable check valve includes a check valve and an unblocking device. The unblocking device is actuatable by a control pressure from a second pressure adjusting device.

Abstract: A method for operating a transmission device for a motor vehicle. A driving gear is selected from a quantity of driving gears and set to the transmission. At the same time, in a normal operating state, the driving gear quantity is compiled from a specific number of driving gears contained in a total quantity of the driving gears, containing all of the driving gears. The driving gear quantity is compiled as a function of at least one state variable of the motor vehicle.

Abstract: A vehicle includes a transmission and a controller. The transmission has clutches and multiple speed ratios that are established during gear upshifts upon torque being transferred from off-going to oncoming clutches. The controller is programmed to, in response to a difference between actual and target times of a desired flare at a transmission input exceeding a threshold during an upshift, adjust the torque of the off-going clutch during a torque transfer phase of a subsequent upshift based on the difference.

Abstract: Methods and systems are provided for a vehicle hill control. An example of a method may include during a vehicle stopped condition, operating with a clutch of a transmission engaged to mechanically lock the transmission, the transmission having a plurality of power inputs including receiving input from an electric machine and a prime mover; releasing at least one of the clutch or a service brake, and while releasing, concurrently adjusting an output magnitude of the electric machine responsive to speed control to control to a zero vehicle speed. In some examples, the method may further include learning a torque output of the electric machine required to maintain the zero vehicle speed upon fully releasing the clutch or service brake. In an example, the method may include estimating a road grade based on the learned torque output.

Abstract: Lock-up clutch engagement hydraulic pressure learning control can be precisely performed by starting lock-up clutch engagement control and executing the lock-up clutch engagement hydraulic pressure learning control after execution of shift control is completed, in a case where the lock-up clutch engagement control is limited in a shift stage before execution of the shift control, when the shift control is executed in a state where a multi-disc lock-up clutch is released. Meanwhile, a decrease in fuel efficiency performance and a direct steering feeling is minimized by starting the lock-up clutch engagement control during shift control in a case where the lock-up clutch engagement control is not limited.
