摘要： PROBLEM TO BE SOLVED: To compatibly attain the following capability and responsiveness of a transmission device whose gear ratio can be continuously changed. SOLUTION: In a vehicle 10 with a CVT 300, an ECU 100 executes basic control. In the basic control, feedforward control based on a degree of change of a target input rotating speed for a predetermined past period and feedback control based on a deviation between a target input rotating speed NINT and an input rotating speed NIN are executed to converge the input rotating speed NIN to the target input rotating speed NINT. When a required shift speed DNINSTA is an upper limit shift speed DNINGRD or higher during shift, the ECU 100 initializes a remainder value excluding a latest value out of a target primary sheave position variation DXT which is calculated in a plurality of set timings for the predetermined past period and served for averaging processing during calculating a feedforward controlled flow amount Qff, to be the latest value.

摘要： PROBLEM TO BE SOLVED: To satisfy both of fuel consumption and drivability in controlling the speed change of a CVT etc. SOLUTION: An ECU 100 executes the speed change processing. In the processing, required acceleration "at" is achieved, and is compared with a preset threshold value "atth". When the required acceleration "at" is larger than the threshold value "atth", it is intended to suppress the deterioration of the drivability due to the inertia torque accompanying the speed change operation. For this purpose, a target input shaft rotational speed "Vina" is set on a low rotational speed side lower than the rotational speed of an engine corresponding to the optimum fuel consumption operating point to be set as the target input shaft rotational speed "Vina" when the required acceleration "at" is not larger than the threshold value "atth". When an input shaft rotational speed "Vin" has reached to the target input shaft rotational speed "Vina" in the speed change processing, the target input shaft rotational speed "Vina" is reset to the value in an ordinary time, and the speed changing operation is continued. In this case, a speed changing speed "Vcvt" is set to "Vcvt2" lower than a reference speed change speed "Vcvt1". COPYRIGHT: (C)2009,JPO&INPIT
摘要翻译：要解决的问题：为了在控制CVT等的变速的同时满足燃料消耗和驾驶性能。解决方案：ECU100执行变速处理。在处理中，实现所需的加速度“at”，并与预设的阈值“atth”进行比较。当所需的加速度“at”大于阈值“atth”时，旨在抑制伴随变速操作的惯性转矩引起的驾驶性能的劣化。为此，将目标输入轴转速“Vina”设定在比设定为目标输入轴转速“Vina”的最佳燃料消耗运转点对应的发动机转速低的低转速侧，当所需的加速度“at”不大于阈值“atth”时。在变速处理中，当输入轴转速“Vin”达到目标输入轴转速“Vina”时，目标输入轴转速“Vina”在常规时间内复位为该值，操作继续。在这种情况下，速度变化速度Vcvt被设定为低于基准速度变化速度Vcvt1的“Vcvt2”。版权所有（C）2009，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To prevent a failure in engagement while suppressing a shifting shock in an automatic transmission. SOLUTION: An ECU 100 of a vehicle 10 performs shift control processing. In the processing, when performing a predetermined upshift operation, intermediate correction of a duty ratio is executed during oil pressure increase control by gradual decrease of the duty ratio of a hydraulic frictional engagement device, so that the duty ratio is temporarily increased. Accordingly, the oil pressure is decreased and engagement force of the frictional engagement device is reduced. An increasing amount of the duty ratio at that time is so determined as to suppress the shifting shock by sequentially learning the learning intermediate correction amount. Meanwhile, when a failure in connection occurs just before the shifting is completed, the duty ratio increasing amount in the intermediate correction is controlled to decrease based on the decreasing intermediate correction amount smaller than the learning intermediate correction amount. At the next shifting timing, the oil pressure during the intermediate correction is increased to thereby prevent a failure in engagement. COPYRIGHT: (C)2008,JPO&INPIT
摘要翻译：要解决的问题：为了防止接合失败同时抑制自动变速器中的换档冲击。车辆10的ECU100进行变速控制处理。在该处理中，当执行预定的升档操作时，通过逐渐降低液压摩擦接合装置的占空比，在油压增加控制期间执行占空比的中间校正，使得占空比暂时增加。因此，油压降低，摩擦接合装置的接合力降低。通过依次学习学习中间校正量来确定此时占空比的增加量，以便抑制换档冲击。同时，当恰好在变速完成之前发生连接失败时，基于小于学习中间校正量的减小中间校正量来控制中间校正中的占空比增加量减小。在下一个换档时刻，中间校正期间的油压增加，从而防止接合失败。版权所有（C）2008，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a shift controller of a continuously variable transmission capable of properly calculating and displaying a gear ratio for display corresponding to an actual gear ratio in the entire part of an operating range.
SOLUTION: This shift controller can set a known shift stage gear ratio corresponding to the gear ratio for display beforehand and an unknown shift stage gear ratio not corresponding to the gear ratio for display beforehand. The shift controller allocates the gear ratio for display for the unknown shift stage gear ratio as a value between the gear ratios for display corresponding to the known shift stage gear ratio on the high speed stage side and the low speed stage side by using a relative relation of an input side rotational speed at the known shift stage gear ratio on the high speed side where an output side rotational speeds at the unknown shift stage gear ratio are the same and an input side rotational speed is low to an input side rotational speed at the known shift stage gear ratio on the low speed stage side where the output side rotational speeds are the same and the input side rotational speed is large. In this case, the shift controller comprises gear ratio calculation means (S10, S11) for display adopting the input side rotational speed not limited by the upper limit nor lower limit.
