    • A control system for an automatic transmission is provided with a manual shift mode capable of performing a shift command made by manual operation. While in the manual shift mode and during the operation of a downshift command generated by a shift lever, a manual shift control unit calculates a degree of power required by a driver that, for example, takes into consideration an operation intent of the driver and a road condition. A post-downshift shift speed is then determined in accordance with the degree of required power and downshifting performed. By performing only one downshift command through manual operation, downshifting in accordance with the degree of power required by the driver is performed. Downshifting to a shift speed desired by the driver can thus be promptly performed, without the operation becoming a burden.
    • 用于自动变速器的控制系统具有能够执行通过手动操作进行的换档指令的手动换挡模式。 在手动换挡模式下,在换挡杆产生的降挡指令的操作期间,手动变速控制单元计算驾驶员要求的功率,例如考虑驾驶员的操作意图和 道路状况。 然后根据所需功率和降档的程度来确定降档换档速度。 通过手动操作仅执行一个降档指令,执行根据驾驶员所需功率的降档。 因此可以迅速地执行降档到驾驶员期望的换档速度,而不会使操作变成负担。

    • The control system for a linear solenoid valve controls output of an oil pressure according to a current value to be fed to the linear solenoid which operates the linear solenoid valve. A solenoid current monitor detects the current value fed to the linear solenoid and an IG voltage monitor detects the voltage level of the battery. A linear solenoid current value setting unit sets a target current value according to a target oil pressure level and a duty ratio setting unit sets a duty ratio for applying the battery voltage to the linear solenoid on the basis of signals coming from the current monitor, the voltage monitor and the current value setting unit. A solenoid driver applies the battery voltage to the linear solenoid for a predetermined period in accordance with the duty ratio set by the duty ratio setting unit. The duty ratio setting unit, in turn, includes: a feedback correction unit for feedback correction of the duty ratio, in accordance with the difference between the current value detected by the monitor and the target current value set by the current value setting unit, so that the current value fed to the linear solenoid approaches the target current value; and a voltage correction unit for further correcting the duty ratio, as previously corrected by the feedback correction unit, on the basis of the voltage level of the battery, as detected by the voltage monitor.
