摘要： A control device for an automatic transmission is disclosed wherein a shift point depending on a variation in vehicle acceleration is modified on a real time basis in accordance with not only a corrected result on a shift point depending on piece-to-piece variations of automatic transmissions, but also actual acceleration for shortening a time required for learning with high precision with no need to be matched. Shift point real-time modifying means is provided for modifying the altered shift point based on a value of a ratio between a value of actual engine-rotation acceleration at an upshift-determining timing during a power-on running and a value of reference engine-rotation acceleration obtained by substituting a value of actual engine-rotation acceleration to a value for a reference running state having no impact on acceleration of a vehicle, and a target maximum engine rotation speed.

摘要： A controller (30) of an automatic transmission (13) can be set to be in a first control mode and a second control mode for controlling a transmission gear ratio (SR) of the automatic transmission (13). The controller (30) in the second control mode automatically changes the transmission gear ratio (SR). The controller (30) obtains an index value and upper limit speed (Lim) of rotation speed (Nout) of a transmission output shaft. The controller (30) in the first control mode allows the transmission gear ratio (SR) to be changed when an operation member (22) is operated to increase the transmission gear ratio (SR) and the index value is equal to or lower than the upper limit speed (Lim). The controller (30) has a setting section (S13) that sets the upper limit speed (Lim). The setting section (S13) sets the upper limit speed (Lim) based on vehicle acceleration (AR) when the controller (30) is in the first control mode and the operation member (22) is operated to increase the transmission gear ratio (SR).

摘要： If a mode-detection value is switched from an automatic shift-mode to a manual shift-mode, a T-ECU changes a shift-stage to a speed lower than a speed that is obtained before the switching of the mode-detection value. The T-ECU determines that a state of the T-ECU returns to a recognizable-state, in which a mode-selection value can be recognized, from an unrecognizable-state, in which the mode-selection value cannot be recognized. The T-ECU sets the shift-stage to a hold value after the return. The T-ECU controls the shift-stage in the automatic shift-mode “D” over a standby-period after the return. The T-ECU controls the shift-stage in the automatic shift-mode “D” until the detection of the operation of the shift-lever after the standby-period passes.

摘要： A control apparatus for a vehicular drive system, including uphill-drive-force control means and constructed to reduce a degree of uneasiness to be given to the vehicle operator during an uphill-road running of a vehicle. The uphill-drive-force control means is arranged to increase a vehicle drive force during the uphill-road running of the vehicle at a given required vehicle output as compared with a vehicle drive force during a level-road running of the vehicle at substantially the same required vehicle output, for obtaining substantially the same value of acceleration of the vehicle during the uphill-road running as that during the level-road running. Delay control means (131) is provided for delaying initiation of an uphill-drive-force control by the uphill-drive-force control means (130), until first period determining means (130) has determined that a time period Tα1 during which acceleration difference G′ between reference acceleration Gb and actual acceleration Gs of the vehicle is larger than predetermined uphill-roadway determining threshold α had exceeded a predetermined first time period T1, so that the vehicle drive force F is not increased for the predetermined first period T1 after the moment of initiation of the uphill-road running which requires the uphill-drive-force control by the uphill-drive-force control means 130, whereby immediately after initiation of the uphill-road running, the vehicle operator can feel a decrease of the vehicle acceleration G as expected upon initiation of the uphill-road running, so that the vehicle operator is less likely to feel uneasy during the uphill-road running.

摘要： A control system of a continuously variable transmission for a vehicle compensates for delays in an estimated input torque TINE based on a gradient value (variation) of the estimated input torque TINE,. For example, a friction force being applied to a driving belt of a continuously variable transmission is regulated according to the compensated estimated input torque TINE. Accordingly, an appropriate torque transmitting capacity is maintained in the transmission even at a rapid accelerating operation of the vehicle, while realizing good fuel efficiency.
