    • An electronic transmission control system having a fail-safe system for an automotive vehicle with a continuously variable automatic transmission whose speed-change ratio (i p ) is changeable continuously depending on vehicle speed (VSP) and engine load (TVO), comprises a hydraulic modulator (12,13,14,15,16,21,25,26) producing at least a regulated line pressure (P L ) necessary to adjust the speed-change ratio (i p ) hydraulically, a desired speed-change ratio arithmetic processing section for calculating a desired speed-change ratio (N pri /N sec ) based on the vehicle speed and the engine load, and a desired line pressure arithmetic processing section for retrieving a desired line pressure (P LO ) based on the speed-change ratio (N pri /N sec ) and the engine load (TVO) from a predetermined characteristic map (Fig.5). Also provided is a fail-safe section (30,40,steps 44 or 54) comprising a comparing portion for comparing the desired line pressure (P LO ) to a predetermined line pressure threshold (D S1 ,D S2 ) above which the desired line pressure (P LO ) is within an unreasonably high line pressure zone, a decision portion for deciding whether the desired line pressure (P LO ) is above the predetermined line pressure threshold (D S1 ,D S2 ), and a speed-change ratio retaining portion for retaining the speed-change ratio (i p ) unchanged, when the desired line pressure (P LO ) exceeds the predetermined line pressure threshold (D S1 ,D S2 ).

    • A positional determination device which is drived according to the pulse signals output to a stepping motor 1 and displaces a nut 2 to a position corresponding to the degree of rotation. In order to adjust the initializing position of a feed mechanism, the stepping motor 1 is rotated and the nut 2 displaces until it reaches the limiting position (LimA) defined by the stopper 3a. When initializing, the pattern of temporarily stopping the stepping motor 1 for a period corresponding to a pulse number (N2) at each pulse number (N1) and rotating is repeated. As a result the rotations of the stepping motor 1 become gentle and even if the nut 2 were to collide with the stopper 3a at the limiting position, the reverse rotation of the stepping motor 1 can be prevented and accurate adjustment of the initializing device can be performed.
    • 一种位置确定装置,其根据输出到步进电动机1的脉冲信号被驱动,并将螺母2移位到与旋转度相对应的位置。 为了调整进给机构的初始化位置,使步进电动机1旋转,并且螺母2移动,直到达到由止动件3a限定的极限位置(LimA)。 当初始化时,重复在每个脉冲数(N1)下暂时停止步进电动机1与脉冲数(N 2)相应的周期和旋转的模式。 结果,步进电动机1的旋转变得平缓,并且即使螺母2在极限位置与止动件3a碰撞,也可以防止步进电动机1的反向旋转,并且能够准确地调节初始化装置 执行。
