Abstract: A clutch control apparatus for a vehicle provided with a hydraulic clutch in the middle of a power transmission path between an engine and a drive wheel. Before the clutch of the vehicle is brought into an engagement state, intermittent hydraulic pressure Y is applied to the clutch while maintaining the clutch in a disengagement state, and thereafter a predetermined hydraulic pressure is applied to the clutch to bring it into the engagement state. A solenoid valve is provided to control hydraulic pressure supplied to the clutch. Before the clutch is brought into the engagement state, a pulsed drive current D is supplied to the solenoid valve. The clutch control apparatus so configured suppresses a motion delay at the time of engaging the clutch, thereby allowing a quick and smooth start and shifting of the clutch.

Abstract: A torque transmission unit is connectable to an internal combustion engine in order to drive a secondary unit with different transmission ratios in dependence upon the rotation rate of the internal combustion engine so that in the case of a low rotation rate of the internal combustion engine the transmission ratio is greater and in the case of a great rotation rate of the internal combustion engine the transmission ratio is less. The torque transmission unit comprises a planetary gear, a free-wheel and a clutch. By the clutch a part of the planetary gear can be coupled to or separated from another part of the planetary gear or a stationary support part, according to choice. The clutch is hydraulically actuable. The pressure for the hydraulic actuation of the clutch is delivered by a hydraulic pump which is integrated into the torgue transmission unit and is independent from the lubricant circuit of the internal combustion engine.

Abstract: A hydraulic control system shifts an automatic transmission into at least a reverse range and a drive range having several forward speed gears by selectively coupling a plurality of frictional coupling elements, including a reverse coupling element. The control system includes a throttle, such as an orifice, for regulating hydraulic pressure applied to the reverse coupling element. A bypass circuit is provided in the control system for applying the hydraulic pressure, bypassing the throttle, to the reverse coupling element. The bypass circuit is opened when a specific operating condition of the automatic transmission of an engine is created, so as to apply the hydraulic pressure through the bypass circuit to the reverse coupling element to rapidly achieve a coupling of the reverse coupling element.
