The invention concerns a method for operating a brake back-up system () of a motor vehicle (), with the steps:

Method for operation of a brake back-up system of a motor vehicle

A method and system for operating a vehicle that includes a driveline disconnect clutch and a step-ratio transmission is described. In one example, the method includes shifting the step-ratio transmission to neutral and accelerating an engine to an expected input shaft speed of the step-ratio transmission via applying full output capacity of an electric machine to the engine.

Method and system for starting an engine

Systems and methods for operating a vehicle that includes an engine and an electric machine are described. In one example, an actual total number of transmission gear downshifts are counted to determine whether or not a transmission clutch characterization is immature. The transmission clutch characterization may be adjusted if it is determined to be immature.

Methods and system for adapting operation of a transmission clutch

Methods and systems for controlling a transmission coupled to an engine during an engine start are presented. In one example, a method adjusts a transmission tie-up force in response to an indication of transmission slip. The method may improve vehicle launch for stop/start vehicles.

Method for controlling a transmission coupled to an engine that may be automatically stopped

A control system and control method for a swap-shift transmission having auxiliary and main gearsets wherein precise synchronization control of ratio changes of each gearset at the start and at the end of a swap-upshift progression is achieved using an adaptive control to adjust friction element pressure values and slip times for friction elements of each gearset, whereby shift synchronization is achieved throughout the operating life of the transmission.

Electronic adaptive swap-shift control for an automatic transmission for automotive vehicles

An adaptive pressure control method for synchronous downshifts in an automatic transmission that uses pressure actuated friction elements. The method uses characteristic parameters that determine downshift quality for both power-on downshifts and power-off downshifts. Selected measured variables are monitored to detect changes in the parameters. Adjustments for the friction elements are made in response to changes in the measured variables.

Adaptive pressure control method for synchronous downshifts in a multiple-ratio transmission

An adaptive shift control method for a geared multiple ratio transmission having friction elements for clutches and brakes to establish and disestablish gear ratio changes wherein at least one ratio change involves engagement of one friction element in synchronism with disengagement of another friction element. Operating parameters are adapted throughout the life of the transmission to reduce synchronous errors by developing and learning pressure and time adjustments for the friction elements.
