摘要： A twin clutch type speed change control system changes over the gear position by switching between a pair of clutches, to reduce the collision sound generated between a free gear and a slide member at the time of changeover of the gear position. In the twin clutch type speed change control system designed to perform gear position changeovers between odd-ordinal gear positions and even-ordinal gear positions through a process in which an engaged clutch is disengaged whereas a disengaged clutch is engaged, the formerly disengaged clutch is supplied with a minute oil pressure P1 toward the clutch engaging side and is thereby preliminarily moved by a minute amount toward the clutch engaging side, at the time of changeover of the gear position.

摘要： 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.

摘要： A clutch control system for a twin-clutch type automatic/manual transmission AMT includes a hydraulic pump for driving a first clutch and a second clutch and oil passages for transmitting oil pressures and an AMT control unit for controlling the supply of oil pressures into the oil passages. Upon detection of an engine starting operation, the AMT control unit performs an initial preparatory operation in which the oil pressures are supplied into the oil passages at different timings so as to fill up the oil passages with a working oil, thereby completing the preparations for driving of the clutches. When the oil pressure is supplied into the oil passage after a predetermined oil pressure is generated in the oil passage, the period of time taken for a first speed gear to become usable is shortened, whereby a swift vehicle starting after the starting of the engine can be achieved.

摘要： Oil pressure detecting means 150 detects a clutch oil pressure in driving a clutch in its engaging direction against a biasing force of a return spring 12 for normally disengaging the clutch. Stroke end detecting means 140 detects that the clutch has reached a stroke end position where clutch disks are in contact with each other when the amount of change in clutch oil pressure becomes larger than a predetermined value. Clutch control correction amount calculating means 130 calculates a work load generated in the return spring 12 according to the clutch oil pressure detected at the stroke end position and then calculates a control correction amount for the clutch according to the difference between the work load calculated above and a predetermined reference value.

摘要： In a clutch control system for a vehicle having a hydraulic type clutch in the course of power transmission between an engine and a drive wheel the operational response of the clutch is enhanced and the influence of a hysteresis present in oil pressure-stroke characteristic is suppressed. When the clutch is disconnected, a control oil pressure thereof is maintained at a predetermined stand-by oil pressure (allowance compensating oil pressure) P1. At the time of connecting the clutch, the control oil pressure is increased to a predetermined connection oil pressure P2. In bringing the clutch from the connected state into the disconnected state, the control oil pressure is lowered to an oil pressure P3 being below the stand-by oil pressure P1 and being near 0, and is thereafter increased again to the stand-by oil pressure P1.

A twin clutch type speed-change apparatus includes a transmission having a plurality of gear pairs between a main shaft and a countershaft and a twin clutch. The rotational drive force of the engine is connected/disconnected between the transmission and the engine by the twin clutch. A dog clutch with dog teeth and a dog hole is applied between an axially slidably attached slidable gear and an axially non-slidably attached non-slidable gear to select an on gear pair for transmitting the rotational drive gear, from a plurality of gear pairs in the transmission. Rotational drive force is transmitted between the slidable gear slid by a shift fork and the coaxially adjacent non-slidable gear by engagement of the dog clutch.

摘要： In a twin clutch type speed change control system in which changeover of gear position is carried out by switching between a pair of clutches, to suppress the noises of clutch being in the disengaged condition during a normal operation with a fixed gear position. In the twin clutch type speed change control system, changeover of gear position between an odd-ordinal gear position and an even-ordinal gear position is effected by disengaging an engaged clutch and engaging a disengaged clutch. During the normal operation with a fixed gear position, the clutch being in the disengaged condition is supplied with a minute oil pressure toward the clutch engaging side, whereby the clutch is moved by a minute amount toward the clutch engaging side.
