摘要： Control system for a pressure medium operated clutch (1) and reduction gear unit (4) to qualitatively improve torque reversal gear shifts by measurement of rotational speeds of the gear unit input shaft (41) and the turbine shaft (320) of a torque converter (3) through sensors (51, 52) and determination of differential speed conditions by an electronic unit (5) to which the sensors are connected. Upon displacement of the gear shift lever from neutral to gear drive position, the electronic unit issues a corrective fuel controlling command through line (22) for a length of time sufficient to obtain equality between the turbine speed (Nt) and the gear input speed (Ni) plus a correction factor (AN). The corrective command is applied to a control lever (71) of the engine fuel injection pump (7) through an automatic operating arrangement (90) superimposed on the fuel control linkage (8) connected to the control lever.

摘要： A method and apparatus for controlling a clutch-transmission unit which makes it possible to intentionally influence the selection of the shifting steps by a parameter which is gained from the detected and stored values of the drive pedal position. Together with further parameters such as transverse acceleration, deceleration and coasting operation, the transmission control is matched optimally to the driving style of the respective driver and to the traffic situation which prevails at that moment.

摘要： A clutch-to-clutch power-on downshift in a motor vehicle automatic transmission is effected by reducing the torque capacity of the off-going clutching device to permit the transmission input speed to increase toward a target speed which it will finally attain subsequent to the shift; increasing the torque capacity of the off-going clutching device and preparing the on-coming clutching device when the input speed approaches its target speed so that the input speed is held near the target speed by the time the on-coming clutching device is prepared to transmit torque; and concurrently applying and releasing the on-coming and off-going clutching device to complete the shift. Since the input speed is substantially at its target value when the exchange of clutching devices occurs, a high quality shift with minimal driveline torque disruption results.

摘要： To control the pressure p of an operating fluid in an automatic transmission (12), the input speed and output speed (n.sub.T, n.sub.out) of the transmission is sensed, and the pressure (p) is so controlled by a control unit (21) that the transmission ratio which is actually coupled by the transmission, in view of the pressure set by the friction bands, is carried out in accordance with a predetermined timing function (i.sub.com), for example as stored in a read-only memory (ROM, 24). Change in shifting characteristics can be obtained, for example, by operator-selected different time-engagement relationships to obtain maximum passenger comfort or maximum acceleration, or intermediate relationships.

摘要： The invention relates to a variable-speed transmission for motor cars, in particular a manual gear-box in the form of a synchronized lay-shaft transmission having several forward speeds and one reverse motion, in which the gears of the reverse motion (11, 12) are also constantly meshing and in which the pairs of gears are selectively shifted into the flux of forces by means of a shifting clutch (13). In order to permit low-noise shifting into the reverse motion, the latter (11, 12) is provided with a synchronizer unit (17, 23). Considering, however, that this creates the risk that the reverse gear may be put in while the car is moving forward, a stop (9, 23) can be moved into the path of transmission of motion between a shift lever to be actuated by the driver and the shifting clutch (13) for the reverse motion, which stop occupies the engaged position when a predetermined traveling speed is exceeded and acts in this engaged position to block the actuation of the shifting clutch (13) for the reverse motion (11, 12) (FIG. 1). The stop is incorporated into the shifting clutch for the reverse gear.

摘要： A system includes a driveline, a user interface, and a control system. The driveline includes an engine, a transmission, and a clutch positioned to selectively couple the engine to the transmission. The user interface is configured to facilitate operator shifting of the transmission. The control system is configured to perform a transmission auto-shift procedure where the control system monitors engine speed of the engine for a period of time following completion of a downshift event with the transmission from a first, higher gear to a second, lower gear, compares the engine speed to at least one speed threshold, and automatically upshifts the transmission from the second, lower gear back to the first, higher gear (i) following expiration of the period of time and/or (ii) in response to the engine speed exceeding the at least one speed threshold during the period of time.

摘要： A method for performing rotational speed synchronisation of a first transmission component having a first initial rotational speed with a second transmission component having a second initial rotational speed, so that they rotate with the same final rotational speed during a gear switch from an initial driving gear to a final driving gear in a stepped gear transmission for a hybrid electric or electric drive train having an electric traction motor. The method including calculating a total frictional work resulting from performing the total rotational speed synchronisation by means of a mechanical synchroniser of the stepped gear transmission only, and if the calculated total frictional work exceeds a maximal frictional work of the mechanical synchroniser, performing the rotational speed synchronisation by means of both the electric traction motor and the mechanical synchroniser.

摘要： A method of controlling a continuously variable electric drivetrain (CVED) including a high ratio traction drive transmission and at least one of a first motor-generator and a second motor-generator is disclosed. The method includes the steps of receiving an output speed, determining a kinematic output speed, and determining a slip state of the high ratio traction drive transmission based on a comparison of the output speed to the kinematic output speed.
