摘要： In a toroidal continuously variable transmission for a vehicle, either of an automatic operation mode and a manual operation mode is selected by a driver via a selector lever (59). A speed ratio grade in the manual operation mode is also designated via the selector lever (59) by the driver. A controller (61) is programmed to control a speed ratio of the transmission to a target speed ratio corresponding to the designated speed ratio grade. The controller (61) is further programmed to prevent the speed ratio from varying after an input torque to the transmission has changed. This control may be realized by setting different target speed ratios for an identical speed ratio grade according to the input torque of the transmission.

摘要： A first final target input rotation speed is calculated according to a throttle opening and a vehicle speed, and a second final target input rotation speed is calculated by applying an upper limit to the first final target input rotation speed. The upper limit is determined so as to reduce noise outside the vehicle. A second final target speed ratio is set from the vehicle speed and second final target input rotation speed, and a time constant of a speed ratio variation is determined from the vehicle speed and first final target input rotation speed. By transiently controlling the speed ratio variation using the second final target speed ratio and time constant thus obtained, an excessive increase of engine rotation speed is prevented while retaining a desirable feeling of acceleration when there is a kickdown operation of the vehicle.

摘要： A controller (61) calculates a transient target speed ratio based on a final speed ratio set according to a vehicle running condition and second order delay time constant gains (75, S99), and control a speed ratio of a continuously variable transmission to the transient target speed ratio via an actuator (4) (87, S103). The controller (61) also calculates the deviation between the final target speed ratio and transient target speed ratio (74, S95), and determines the second order delay time constant gains based on the deviation (74, S98). Preferably, the gains are determined so that the response rate is slower the larger the deviation (74, S134, S135, S136, S137, S139, S140, S141).

摘要： A speed change control device for an automatic transmission wherein the speed ratio is automatically varied according to a running state when an automatic shift mode is selected, and the speed ratio is varied based on a manual operation when the manual shift mode is selected. When there is a change-over from the automatic shift mode to the manual shift mode, a speed ratio immediately after the change-over is set to a speed ratio such that a transmission input rotation speed after the change-over increases by at least a predetermined rotation speed compared to the transmission input rotation speed before the change-over. In this way, the effectiveness of engine braking is enhanced immediately after a change-over to the manual shift mode, or a downshift for acceleration can be definitively performed.

摘要： The vehicle comprises a continuously variable transmission and traction control system (TCS) which controls a driving force. When the TCS is not operating, a controller computes a final target ratio based on a sensor detected vehicle speed. When the TCS is operating, the final target ratio is computed based on an estimated vehicle speed, and the final target ratio is limited by a speed ratio upper limiting value computed based on the sensor detected vehicle speed. The controller controls a speed change actuator so that a real speed ratio approaches the final target ratio.

摘要： A first switch (2) which can select a manual mode, and a second switch (5, 6) which can select one of an upshift and a downshift, are provided. A microprocessor (1) varies a speed ratio of an automatic transmission (10) according to the specification of the second switch (5, 6) when the first switch (2) has previously selected the manual mode, and the second switch (5, 6) subsequently specifies one of the upshift and the downshift (S20, S21, S33, S40, S41, S34, S36, S37, S53, S54, S55). On the other hand, variation of the speed ratio of the automatic transmission (10) according to the specification of the second switch (5, 6) is prohibited when the second switch (5,6) specifies one of the upshift and the downshift at a timing not later than a timing at which the manual mode is selected by the first switch (2) (S20, S22, S33, S40, S38, S34, S36, S38, S53, S54, S56). Due to this processing, an unexpected speed ratio variation is prevented from occurring simultaneously when the first switch (2) selects the manual mode in the state where the second switch (5.6) has been fixed in the ON state due to malfunction or misoperation of the second switch (5, 6).

摘要： When a slip control system starts operating, a vehicle speed VSP used for speed change control is simultaneously changed over from a sensor detected vehicle speed VSPSEN to an estimated vehicle speed VSPFL. On the other hand, when the slip control system has stopped, it is first determined whether a speed ratio variation amount, due to the change-over of the vehicle speed used for speed change control from the estimated vehicle speed VSPFL to the sensor detected vehicle speed VSPSEN, is less than a permissible amount. When it is determined that the speed ratio variation amount is smaller than the permissible amount, the vehicle speed used for speed change control is changed over from the estimated vehicle speed VSPFL to the sensor detected vehicle speed VSPSEN. By performing this change-over, a sharp variation of the vehicle speed used for speed change control is suppressed, and a sharp variation of the speed ratio leading to shocks or slipping is suppressed.

摘要： A lock-up torque converter is equipped with a lock-up clutch. The lockup clutch may engage even when the vehicle is coasting (lock-up coasting). When an accelerator pedal is depressed in a stepwise manner during lock-up coasting, the lock-up clutch is temporarily disengaged. By setting the threshold value used for determination so that it is easier to determine that the accelerator pedal was depressed in a stepwise manner the lower the vehicle speed, the dual objectives of vibration suppression of the drive system and improvement of fuel cost-performance are realized.
