    • A control device for controlling a continuously variable transmission (5) is disclosed. The control device has an oil pressure control unit (100) which supplies an oil pressure to a primary pulley (10) and secondary pulley (11) based on a command signal indicative of a target speed-reduction ratio, a sensor (26) which detects a rotation speed (Np1) of the primary pulley (26), and a controller (20) which transmits the command signal indicative of the target speed-reduction ratio to the oil pressure control unit (100). The controller is programmed to set the target speed-reduction ratio to a first speed-reduction ratio (R1); calculate a first predetermined rotation speed (N1) of the primary pulley at which the V-belt reaches a first limiting temperature (T1) at the first speed-reduction ratio (R1); calculate a first elapsed time after the detected rotation speed (Np1) of the primary pulley exceeds the first predetermined rotation speed (N1); maintain the first speed-reduction ratio (R1) when the first elapsed time is equal to or less than a first predetermined time; and set the target speed-reduction ratio to a second speed-reduction ratio (R2) smaller than the first speed-reduction ratio (R1) when the first elapsed time exceeds the first predetermined time. At the second speed-reduction ratio (R2), the temperature of the V-belt should become equal to or less than the first limiting temperature (T1) throughout the permitted rotation speed region of the primary pulley. Thus, starting acceleration performance of the continuously variable transmission is enhanced.
    • 公开了一种用于控制无级变速器(5)的控制装置。 控制装置具有油压控制单元(100),其基于表示目标减速比的指令信号向主滑轮(10)和次滑轮(11)供给油压;传感器(26),其 检测主滑轮(26)的转速(Np1),以及向油压控制单元(100)发送表示目标减速比的指令信号的控制器(20)。 控制器被编程为将目标减速比设置为第一减速比(R 1); 以第一减速比(R 1)计算V带达到第一极限温度(T 1)的初级带轮的第一预定转速(N 1); 计算出初级带轮的检测转速(Np1)超过第一预定转速(N 1)之后的第一经过时间; 当第一经过时间等于或小于第一预定时间时,保持第一减速比(R 1); 并且当所述第一经过时间超过所述第一预定时间时,将所述目标减速比设定为小于所述第一减速比(R 1)的第二减速比(R 2)。 在第二减速比(R 2)下,V带的温度应在主带轮的允许转速区域内等于或小于第一极限温度(T 1)。 因此,提高了无级变速器的起动加速性能。

    • An oil pressure control device, which changes a range of a vehicle transmission includes: a pressure adjusting device that engages or releases forward and reverse frictional-engagement devices by adjusting an oil pressure supply, a sensor that detects a range selected by a vehicle driver, and a controller that controls the clutch pressure adjusting device based on a signal from the sensor. When the stop range is selected after selecting the reverse (forward) range, a forward (reverse) range is selected. After supplying an initial oil pressure to the forward (reverse) frictional-engagement device, the pressure adjusting device is controlled so that the pressure decreases from the initial oil pressure to a predetermined oil pressure. Subsequently, the oil pressure is initially increased at a small increase rate from the predetermined oil pressure. After a predetermined time period has elapsed, the pressure adjusting device increases the oil pressure at a large increase rate.
