摘要： A controller determines whether or not the vehicle dynamics controller is operating, and when it is determined that it is operating, a speed change operation by an actuator which changes over a gear position of the automatic transmission is prohibited. This speed change prohibition is continued for a predetermined time even when the vehicle dynamics controller has stopped. In this way, control performance of the vehicle dynamics controller is prevented from becoming unstable due to a speed change of the automatic transmission.

摘要： When a slip control system is not operating, a speed ratio control device uses a sensor detected vehicle speed for speed ratio control, and when the slip control system is operating, it uses an estimated vehicle speed for speed ratio control. It is determined whether a variation amount of the estimated vehicle speed is greater than a threshold set to a variation amount which could not be obtained when there is no error. When the variation amount of the estimated vehicle speed is greater than the threshold, it is determined that the estimated vehicle speed is abnormal, and use of the estimated vehicle speed for speed ratio control is prohibited.

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 speed ratio of a toroidal continuously variable transmission is varied by a step motor (4). The step motor (4) is responsive to a command signal Astep which a controller (61) outputs corresponding to a target speed ratio. The controller (61) is programmed to initialize the command signal Astep when it is activated while the vehicle is running (S152) such that the command signal coincides with an actual operation position of the step motor (4). The controller (61) is further programmed to limit the command signal, after performing this initialization, within a first limiting range which is narrower than a second limiting range corresponding to a physical operation limit of the step motor (4) (S168, S170). By applying such a limitation to the command signal, the command signal is prevented from exceeding the operation limit of the step motor (4) even when a torque shift error is introduced into the command signal by the initialization while the vehicle is running.

摘要： After an engine (1) has started, a controller (6) starts determining whether lockup should be prohibited or permitted based on the cooling water temperature of an engine (1) or the oil temperature of a transmission (2). Once it has been determined that lockup should be permitted, the controller (6) stops determining whether lockup should be prohibited or permitted until the next time the engine (1) is started. In this way, once the conditions for determining that lockup should be permitted hold, lockup prohibition or permission based on the engine cooling water temperature or transmission oil temperature is no longer determined, so repeat engaging and disengaging of the lockup clutch (5) due to fluctuations of engine cooling water temperature or transmission oil temperature, is prevented.

摘要： In a vehicle continuously variable transmission, an engine rotation speed, input rotation speed of the transmission and an output rotation speed of the transmission are respectively detected by sensors (64, 65, 68). Based on the output signals from these rotation speed sensors (64, 65, 68), a controller (61) controls a speed ratio of the transmission within a predetermined speed ratio range. The controller (61) also determines if any of the rotation speed sensors (64, 65, 68) has an abnormality based on the output signals from these sensors (64, 65, 68) and narrows the predetermined speed ratio range (S234) when any of the sensors has been determined to have an abnormality, so as to prevent an extraordinary speed ratio control from being performed.

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： In a vehicle automatic transmission, a controller (61) feedback controls a speed ratio command signal by proportional/integral/differential (PID) control so as to minimize a deviation between a transient target speed ratio and a real speed ratio. When a difference between the command signal and that of the preceding control cycle is larger than a predetermined value, the controller (61) prohibits the increase of an integral correction amount of the PID control in the next control cycle. In this way, continuous increase of the feedback correction amount while the transmission can not follow the command signal is suppressed.

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).
