    • A diagnostic system for an automatic transmission is provided in which a microcomputer determines that torque that can drive the driving wheels of the vehicle is not transmitted to an output shaft of the automatic transmission when the vehicle is stopped and the ignition key is operated to the OFF position (steps S1OO, S11O), and performs forced energization of solenoids of solenoid valves associated with respective friction devices of the transmission (step S120), while monitoring current passing through the solenoid valves (step S130). If the current monitored does not match the current for energizing any of the solenoids, the microcomputer determines that the corresponding solenoid valve is at fault. Thus, the diagnostic system appropriately determines the presence of a fault of each solenoid valve for controlling the hydraulic pressure to each friction device, with increased flexibility and freedom.
    • 提供了一种用于自动变速器的诊断系统,其中微型计算机确定当车辆停止并且点火钥匙被操作到OFF时可以驱动车辆的驱动轮的扭矩不被传递到自动变速器的输出轴 (步骤S100,S110),同时对通过电磁阀的电流进行监视(步骤S130),对与变速器的各摩擦装置相关联的电磁阀的螺线管施加强制通电(步骤S120)。 如果监测到的电流与用于激励任何螺线管的电流不匹配,则微机确定相应的电磁阀故障。 因此,诊断系统适当地确定每个电磁阀的故障的存在,用于控制每个摩擦装置的液压,具有增加的灵活性和自由度。

    • ECU 는, 이너셔상의 개시 시점의 오토매틱 트랜스미션의 제 1 입력 토크치를 기억한다 (S112). 이너셔상의 개시 후에 있어서 (S100), 미리 정해진 조작량 이상의 액셀 조작이 이루어지면 (S118), 오토매틱 트랜스미션의 제 2 입력 토크치를 추정한다 (S120). 액셀 개도가 증대되고 (S130), 제 2 입력 토크치가 기억되어 있는 제 1 입력 토크치보다 작으면 (S132), 제 2 입력 토크치가 기억되어 있는 제 1 입력 토크치로 바꾸고 (S134), 기억된 제 1 입력 토크치를, 치환 후의 제 2 입력 토크치로 갱신한다 (S140). 기억된 제 2 입력 토크치에 기초하여, 걸어맞춤 압력을 이너셔상 중에 있어서 점증시킬 때의 구배를 설정한다 (S142).

    • ECU将自动变速器的第一输入转矩值存储在惯性起始点(S112)。 在惯性开始后(S100),如果以预定的操作变量或更大的操作变量执行加速操作(S118),则估计自动变速器的第二输入扭矩值(S120)。 当第二输入转矩值小于存储的第一输入转矩值时(S132),第一输入转矩值改变为第一输入转矩值(S134) 1输入转矩值与更换后的第二输入转矩值进行比较(S140)。 基于所存储的第二输入扭矩值,在惯性阶段期间接合压力增加时设定梯度(S142)。

    • A shift controller of an automatic transmission capable of increasing shift controllability when the transmission cannot be directly shifted to a target gear stage based on a second shift determination. When there are a plurality of representatives for an intermediate gear stage enabling the direct shift of the transmission (S5) when it is impossible to directly shift the transmission to the target gear stage based on the second shift determination (S2) though the second shift determination is performed while shift control to the target gear stage based on a first shift determination is performed (S1), a specific gear stage among the plurality of representatives for the intermediate gear stage where a variation in engine rotational speed (NE) becomes maximum is determined to be the intermediate gear stage (S7). When the variation in engine rotational speed (NE) is large, an allowance is produced also in a time for increasing the hydraulic pressure of an engagement clutch since the variation in engine rotational speed (NE) takes much time. As a result, since the ascending gradient of the hydraulic pressure of the engagement clutch can be gently set up, shift shock can be reduced, i.e., the shift controllability can be improved.
    • 一种自动变速器的变速控制装置,其能够根据第二变速判定在变速器不能直接转移到目标档位时,提高变速可控性。 当存在多个用于中间齿轮级的代表,当不能通过第二换档确定(S2)不可能直接将变速器转换到目标档位时,能够进行变速器的直接换档(S5) 执行基于第一换档确定的目标齿轮级的换档控制(S1)时,确定发动机转速(NE)变化最大的中间齿轮级的多个代表中的特定齿轮级 作为中间档位(S7)。 当发动机转速(NE)的变化大时,由于发动机转速(NE)的变化需要很多时间,所以在增加接合离合器的液压的时间内也产生余量。 结果,由于接合离合器的液压的上升梯度可以轻轻地设置,所以可以减小换档冲击,即可以提高换档控制性。
