摘要： A shift control system for a vehicle transmission with multiple gear trains and a main shaft connected to an engine crankshaft through a clutch. The shift control system allowing shifting without disengaging the clutch. In conducting a shifting operation through a roller synchro mechanism associated with a gear train, the number of revolutions per minute of the engine crankshaft is promptly decreased through at least one of an ignition control device and a fuel supply control means to synchronize the number of revolutions per minute of a main shaft and a counter shaft of the transmission when the number of revolutions per minute of the main shaft is larger than the number of revolutions per minute for synchronizing with the counter shaft and the number of revolutions per minute of the engine crankshaft is increased to synchronize the number of revolutions per minute of the main shaft and the counter shaft when the number of revolutions per minute of the main shaft is less than the number of revolutions per minute for synchronizing with the counter shaft. This enables a prompt shifting.

摘要： An engagement-actuation control for a frictionally engaging element to establish a driving range in response to a shift command to shift from a neutral range to the driving range comprises a plurality of control stages including an invalid-stroke-clearing control. This invalid-stroke-clearing control is finished when invalid-stroke clearing is judged complete on the basis that the absolute value of the rate of rotational change of a turbine shaft is equal to or greater than a predetermined rate and that the difference between the rotational speed of an engine and the rotational speed of the turbine shaft is equal to or greater than a predetermined value.

摘要： An automatic transmission includes a frictionally engaging element for establishing a predetermined speed range. This predetermined speed range may be a second or higher speed range, and it is set temporarily in N-D squat control and also used for establishing a reverse range. In this transmission, engagement-actuation control of the frictionally engaging element for establishing the predetermined speed range which is executed when a shift is made from a N range to a R range comprises a plurality of control stages. When a shift to the R range is made via the N range following a N-D shift, a shift control apparatus detects the engagement condition of the the frictionally engaging element for establishing the predetermined speed range, selects one of the control stages in correspondence with the engagement condition, and initiates the engagement-actuation control of the frictionally engaging element from the control stage selected, so as to execute an engagement control for establishing the reverse range. Thus, in-gear shifts are executed smoothly without any delay in a N-D-N-R range shift.

摘要： A control apparatus for a continuously variable transmission for use with a vehicle is provided for permitting a driver to select one from three transmission modes for the continuously variable transmission, and providing an appropriate transmission ratio in accordance with a particular operating condition of a vehicle without causing an insufficient engine torque or over-revolution, particularly when the transmission is switched from a continuously variable transmission mode to a stepped manual transmission mode. The control apparatus comprises an ECU and an MT switch. The ECU executes a continuous automatic transmission mode for continuously setting a transmission ratio of the continuously variable transmission in accordance with a detected operating condition of the vehicle. The ECU also executes a stepped automatic transmission mode for setting the transmission ratio of the continuously variable transmission to one of a plurality of predetermined transmission stages in accordance with the detected operating condition of the vehicle. The CPU further executes a stepped manual transmission mode for setting the transmission ratio to one of a plurality of predetermined transmission stages in accordance with a driver's intention of transmission. The ECU sets the continuously variable transmission to one of the continuous automatic transmission mode, the stepped automatic transmission mode and the stepped manual transmission mode in accordance with a manipulating state of an MT switch.
