摘要： A traction motor of a hybrid electric vehicle drives a primary pump to provide pressurized hydraulic fluid to engage a power flow path of a multi-ratio transmission. To reduce fuel consumption, the motor is maintained at zero speed until a shift lever is moved into a drive position. After a power flow path is established, the motor speed is again reduced to zero until a driver demands torque by pressing an accelerator pedal. While the traction motor is stationary, an auxiliary pump maintains the fluid pressure to keep the transmission power flow path engaged.

摘要： A hydraulic control system stably controls pressure in a hydraulic chamber of a pulley accommodating a belt by controlling a feeding valve and a discharging valve. The control system reduces a control amount of the feeding valve to be smaller than that calculated based on a pressure difference in a case other than one in which pressure in the hydraulic chamber is increased by delivering oil to another chamber, in case the pressure in the hydraulic chamber is increased by delivering the oil to the other chamber. The control system reduces a control amount of the discharging valve to be smaller than that calculated based on the pressure difference in a case other than one in which pressure in the hydraulic chamber is lowered by discharging the oil from the other chamber, in case the pressure in the hydraulic chamber is lowered by discharging the oil to the other chamber.

摘要： A method for operating a transmission device (1), which is transferable into different operating states through the actuation of shifting elements (A to F), is described. At least one of the shifting elements (A, F) is designed as a positive-locking shifting element, which is supplied with operating pressure (p_sys) for presenting a defined operating state of the transmission device (1). Through a sensor device upstream of a valve device, which is connected to a transmission area essentially featuring ambient pressure, a value of a pressure signal corresponding to the operating pressure can be determined. Upon exceeding a threshold value of the pressure signal, currently in the area of the positive-locking shifting element (A, F), a change in operating state is determined, and, upon falling short of an additional threshold value of the pressure signal, the reaching of the requested operating state is established. In a non-actuated operating state of the positive-locking shifting element (A, F), the pressure in the transmission area (18) is established by the sensor device. Upon the presence of a request for a change in operating state in the area of the positive-locking shifting element (A, F), the threshold valve and the additional threshold value are determined from the sum of the pressure calculated in the transmission area (18) prior to the presence of the request for the change in operating state and a pressure offset value.
