摘要： In case information such as an actual gear ratio is not stored in an EEPROM 28 due to a trouble of a backup power source 29 or like when an initialization operation of a step motor 27 is performed at the time of start of a vehicle or during stoppage of the vehicle, an output torque of an engine is limited before the initialization operation. Thereby, even if an accelerator is depressed during the initialization operation of the step motor 27 in which a sufficient primary pulley pressure cannot be ensured, the output torque of the engine is limited, so that torque inputted to a V-belt type continuously variable transmission is small and slippage does not occurs between the primary pulley and a secondary pulley.

摘要： A system for controlling a V-belt type CVT is constructed to change a first position of a step motor to a second position of the step motor corresponding to a second target shift ratio if it is determined that the primary-pulley pressure fails to reach a predetermined value. The second target shift ratio is on the high-speed side with respect to a third position of the step motor corresponding to a third target shift ratio to be achieved if it is determined that the primary-pulley pressure reaches the predetermined value.

摘要： When a speed of a vehicle is less than 8 km/h, an upshift determination condition is established, an idle switch signal is turned off, and a downshift is detected, an operating speed of the step motor is limited. Thereby, since the operating speed of the step motor is limited even when the vehicle is rapidly decelerated and re-accelerated before a pulley ratio is returned to a lowest value Lo, a shift speed of the downshift performed in the re-acceleration is lowered, and no slippage occurs in a V-belt between pulleys.

摘要： Hydraulic control system and method for an automatic transmission. The hydraulic control system includes a hydraulic pressure source, a flow rate control valve having a spool with an orifice and a drain hole, stroke position determining means, and pressure regulator means. The stroke position determining means determines that the spool is displaced from a large spool-stroke position where a communication area of the drain hole is not less than a first predetermined area, to a small spool-stroke position where the communication area is not more than a second predetermined area. The pressure regulator means regulates a hydraulic oil pressure downstream of the orifice and corrects the hydraulic oil pressure downstream of the orifice by adding a predetermined correction amount for a first predetermined time when the stroke position determining means determines that the spool is displaced from the large stroke position to the small stroke position.

摘要： A transmission controller commands a demand torque of an engine to an engine controller according to an actual secondary pulley pressure that is detected by a secondary pulley pressure sensor when a vehicle speed is 0 km/h and a state wherein gear ratio is equal to or higher than a predetermined gear ratio is continued for a first predetermined time or more. Thereby, since an input torque corresponding to a secondary pulley pressure which is actually generated is inputted to a primary pulley even when a failure occurs in the secondary pulley rotation sensor, engine performance of a vehicle can be ensured.

摘要： When gear ratio is abnormally increased due to failure of a secondary pulley rotation sensor or slip in a V belt, demand torque of an engine is rapidly reduced, and after upper limit regulation of a target secondary pulley pressure is performed for a second predetermined time, control of the target secondary pulley pressure according to an output torque of the engine is performed. Thereby, since an actual torque of the engine does not exceed a belt capacity capable of holding a belt by a secondary pulley pressure which is actually generated, when the secondary pulley rotation sensor fails, no slip occurs in the V belt.

摘要： There are provided with a determination means for determining whether or not the correlation between the pressure value detected by the primary pressure sensor and the pressure value detected by the secondary pressure sensor is an actually impossible relation (Step 5), and a switchover means for switching over to an open control while prohibiting a feedback control when the correlation is determined to have become a relation actually impossible by the determination means (Step 6). Presence or absence of a fault to the primary pressure sensor or the secondary pressure sensor (particularly, fault of fixed output voltage) is judged based on the correlation between the output voltage of the primary pressure sensor and the output voltage of the secondary pressure sensor to prohibit the control of a primary pressure and a secondary pressure using the hydraulic pressure sensors when it is judged that there is a fault.
