摘要： A shift control system for a continuously variable transmission CVT) has a gear ratio controller for controlling the gear ratio of CVT by determining a target gear ratio from a drive point determined on the basis of at least a throttle opening and a vehicle speed. The shift control system also has a vehicle distance controller for maintaining a proper vehicle distance by controlling the throttle opening of an engine. A shift speed control device provided in the gear ratio controller increases the shift speed from the shift speed established at the time the vehicle distance is not controlled by the vehicle distance controller, when the vehicle distance is controlled by the vehicle distance controller.

摘要： A continuously variable transmission 18 changes a speed-change ratio γ so that an actual rotation speed NIN of an input shaft 36 coincides with a target rotation speed NIN* set based on a target output P*. A target output calculating portion 156 calculates a first target drive force related value P1* based on both an acceleration required amount Acc and a load of an auxiliary machine AUX, calculates a second target drive force related value P2* based on the acceleration required amount without considering the auxiliary machine load, and sets the second drive force related value as the drive force related value P* upon a vehicle regular running. Even when the auxiliary machine load fluctuates in the vehicle regular running the target output does not fluctuate, and prevention of fluctuation of the target output rotation speed increases the drivability in the vehicle regular running.

摘要： In a controller for a belt-type continuously variable transmission including a hydraulic actuator that changes a groove width of a primary pulley, a hydraulic actuator that changes a groove width of a secondary pulley, and a belt clamping pressure control solenoid that controls the hydraulic pressure supplied to the hydraulic actuator of the secondary pulley, a mechanism calculates a transmission ratio between the primary pulley and the secondary pulley and determines whether or not there is belt slippage based on that calculated transmission ratio, and a mechanism determines normalcy of the belt clamping pressure control solenoid. The input torque when belt slippage has actually occurred, i.e., when a failure has been determined, is used as a condition when performing the normalcy determination. By setting such a condition, it is possible for a normalcy determination threshold value (input torque value α) used for the normalcy determination to be a small value, and thus it is possible to suppress erroneous normalcy determination.

摘要： In a shift control device for a vehicular continuously variable transmission with an arrangement in which a normal shift mode is switched to an acceleration shift mode in response to an acceleration demand, a shift control is performed to prevent deterioration to running performance due to a transition to the acceleration shift mode by increased running resistance such as ascending road running or the like against a driver will.An acceleration demand determining value PAPL is set depending on a road surface gradient Φ such that the shifting mode is more difficult to be switched to the acceleration shift mode in a larger road surface gradient Φ, than in a smaller road surface gradient Φ. Such arrangement prevents the shift mode from being switched to the acceleration shift mode during ascending road running with an increase in an accelerator operation amount PAP against the driver will. During a flat road running with a small road surface gradient Φ, the shift mode is switched to the acceleration shift mode in response to the acceleration demand by the driver, thereby obtaining an excellent acceleration feeling. Meanwhile, the above arrangement prevents degradation of the ascending performance due to an inadequate drive force resulting from the shift mode switched to the acceleration shift mode during ascending road running against the driver will.

摘要： In an embodiment of the continuously variable transmission control apparatus of the present invention, even if an actual gear change ratio RATIO overshoots a target gear change ratio RATIO T and an upshift gear change instruction (DS1 gear change duty output) is switched to a downshift gear change instruction (DS2 gear change duty output) during gear change due to the upshift gear change instruction, in the case where the upshift gear change speed is fast, specifically, in the case where a maximum actual sheave position change ratio DWDRmax is not less than a determination threshold g, it is determined that the transmission is capable of performing an upshift gear change, and the upshift gear change state is determined to be normal. In this manner, a normalcy determination is performed more frequently.
