Abstract: A vehicle includes an engine, a dual-clutch transmission (DCT), and a controller. The controller executes instructions embodying a method to control a requested change-of-mind shift of the DCT to a second desired gear state. The requested change-of-mind shift is initiated after a prior-requested but not yet fully-executed shift of the DCT to a first desired gear state. Execution of the instructions causes the controller to detect the requested change-of-mind shift, identify the second desired gear state, and abort the prior-requested shift to the first desired gear state immediately upon identifying the second desired gear state. The controller also shifts the DCT to the second desired gear state using a calibrated shift profile corresponding to the detected change-of-mind shift. The calibrated shift profile describes required oncoming and offgoing clutch torques needed for achieving the second desired gear state. Engine speed control may be used to synchronize engine and input shaft speeds.

Abstract: A solenoid actuator for an injection valve or an intake valve is driven with current control during closed-loop control phases. In between the closed-loop current control, the actuator must be clamped to an opposite voltage so as to quickly decrease the current through the solenoid.

If the measured current indicates an extraneous reduction in the current, the clamping phase duration is shortened for the next activation of this clamping phase. If the measured current indicates an insufficient decrease, the clamping phase duration is lengthened for the next following activation cycle.
