    • Disclosed are a control system and a control method for an automatic transmission, in which a judgment is made whether or not a range selector (31) has been switched to a reverse range during forward traveling of the vehicle. When it is determined that the range selector (31) has been switched to the reverse range during forward traveling of the vehicle, a judgment is made whether or not the vehicle speed is lower than a first vehicle speed and whether or not the period of time that has elapsed until switching from the forward to the reverse range is shorter than a predetermined judgment time. When the vehicle speed is lower than the first vehicle speed and the period of time that has elapsed until switching from the forward to the reverse range is shorter than the predetermined judgment time, a forward/backward changeover mechanism (4) is switched to a reverse mode. Otherwise, the switching of the forward/backward changeover mechanism (4) to the reverse mode is delayed.
    • 公开了一种用于自动变速器的控制系统和控制方法,其中判断在车辆前进行驶期间范围选择器(31)是否被切换到倒档。 当在车辆的前进行驶中判定为范围选择器(31)已被切换到倒退范围时,判断车速是否低于第一车速,以及是否该时间段 在从正向切换到反向范围之后经过的时间短于预定的判断时间。 当车速低于第一车速,直到从前进到后退范围切换之后经过的时间段短于预定判断时间时,前/后转换机构(4)被切换为反向 模式。 否则,前进/后退切换机构(4)的切换延迟到倒车模式。

    • A system and method for automatically controlling a vehicle's speed to a desired cruise speed, for a vehicle in which a torque converter and an automatic transmission are mounted are disclosed in which, when the vehicle speed is controlled so as to conicide with the desired cruise speed by means of an automatic (vehicle) speed control device (ASCD) associated with the vehicle engine, deviation of a present vehicle speed from a desired cruise speed is derived. When a first predetermined degree of deviation is reached, the lock-up state of a lock-up device in the torque converter is inhibited. When the deviation further reaches a second predetermined degree of deviation, the second predetermined deviation being greater than the first, the automatic transmission is operated to inhibit a maximum speed gear range (e.g. a fourth speed range is downshifted to a third speed gear range). When the vehicle speed is returned to the cruise speed via the inhibition of the maximum speed gear range, the inhibit is released and thereafter lock-up inhibit is also released.
    • 公开了一种用于将车辆速度自动控制到期望的巡航速度的系统和方法,其中安装有变矩器和自动变速器的车辆,其中当车速被控制以以期望的巡航速度 通过与车辆发动机相关联的自动(车辆)速度控制装置(ASCD),导出当前车速与期望的巡航速度的偏差。 当达到第一预定的偏差时,禁止变矩器中锁定装置的锁定状态。 当偏差进一步达到第二预定偏差时,第二预定偏差大于第一预定偏差,则自动变速器被操作以禁止最大速度档位范围(例如,第四速度范围降档至第三档位范围)。 当通过抑制最大速度档位将车速返回到巡航速度时,禁止被释放,此后也释放锁定禁止。
