摘要： A lock-up clutch of an automatic transmission is controlled by an electronic control unit using a gear shift diagram and a lock-up clutch changeover diagram each having vehicle velocity plotted along identical abscissa and throttle opening plotted along identical ordinate. Changeover of the lock-up clutch is controlled upon setting a changeover line in the changeover diagram in accordance with which the lock-up clutch is changed over from OFF to ON state, and changeover of transmission gear ranges is controlled upon setting a transmission gear range changeover point in the gear shift diagram. The changeover line is set in such a manner that it will not intersect a region in the gear shift diagram where the shift position is 2nd gear range or less and the throttle opening is less than a predetermined value. Thus, the lock-up clutch is not engaged in a case where the transmission is in 2nd gear range or less and, moreover, the throttle opening is less than a predetermined value.
摘要翻译：自动变速器的锁止离合器由电子控制单元控制，该电子控制单元使用变速图和锁定离合器切换图，每个车辆速度沿着相同的横坐标绘制车辆速度，节气门开度沿着纵坐标绘制。控制锁止离合器的切换，在切换图中设置切换线，根据该切换线，锁止离合器从OFF切换到ON状态，并且在设定传动档位范围时控制变速范围的切换变速图中的切换点。转换线的设定方式为与变速档位为2档以下且节气门开度小于预定值的变速图中的区域不相交。因此，在变速器处于2档以下的情况下，锁止离合器不接合，此外，节气门开度小于预定值。

摘要： An exemplary differential output buffer includes a mixing stage and an output stage. The mixing stage includes a mixing circuit that mixes a differential data signal and an inverted delayed differential data signal to generate a mixed differential data signal. The output stage includes a first and a second output stage differential pair of transistors. Sources of the transistors in each of the output stage differential pairs are commonly coupled. Gates of the transistors in the first and second output stage differential pairs are supplied with the differential data signal and the mixed differential data signal, respectively. Drains of corresponding ones of the transistors in the first and second output stage differential pairs are commonly connected to form output nodes to output an emphasized differential data signal. The mixing stage includes a mixing ratio setting circuit that sets the mixing ratio to one of 1:0, 1:1, and 0:1.
