摘要： A vehicle includes a clutch, pump, pressure control variable force solenoid (PVFS) valve in a branch supplying oil from the pump to the clutch through a flow control VFS (QVFS), and a controller. The controller calculates an area of a variable orifice of the QVFS valve at the start of a clutch shift, records the area as a maximum area, and calculates a maximum branch pressure as a function of the area. The controller limits pressure in the branch during the shift event to the calculated maximum branch pressure. The transmission may be a dual-clutch transmission (DCT) with the clutch being a DCT input clutch. A control system includes a host machine, temperature and pressure sensors, a computer-readable medium with instructions for limiting branch pressure as a function of the maximum area noted above and using sensor values from the sensors. A method of limiting branch pressure is also disclosed.

摘要： A method for hydraulically charging a fluid circuit in a vehicle includes calculating a fluid volume of the fluid circuit via a controller, and comparing a speed of the vehicle to a calibrated speed threshold. The method also includes calculating a vehicle deceleration rate when the speed of the vehicle is less than the calibrated speed threshold and the fluid volume is less than a calibrated volume threshold. The fluid circuit is then hydraulically charged to a target volume, using a fluid pump, at a hydraulic charging rate that corresponds to the calculated vehicle deceleration rate. A vehicle includes an engine, transmission having a fluid circuit with a fluid pump, and a controller. The controller executes instructions to charge the fluid circuit according to the method noted above. A system includes the transmission and controller.

摘要： A system includes a pump, accumulator, a sensor which measures line pressure in a fluid circuit, and a controller. The controller plots and calculates respective slopes of first and second sets of measured pressure values from the sensor, calculates a slope ratio, and compares the slope ratio to a threshold. The controller also records the pre-charge pressure as the point of intersection of lines representing the slopes when the ratio exceeds the threshold. A control action is executed when the pre-charge pressure drops below a calibrated minimum threshold. A method includes measuring the pressure values, calculating the respective slopes and the slope ratio, comparing the slope ratio to a ratio threshold, recording the point of intersection of lines representing the slopes as an interpolated pre-charge pressure value when the ratio exceeds the threshold, and executing the control action.
