    • A lock-up control system for a lock-up type automatic transmission.A load detection circuit generates a reference acceleration signal that indicates a reference acceleration, and an actual acceleration signal that indicates an actual acceleration of an automotive vehicle. The circuit compares the actual acceleration signal with the reference acceleration signal for generating a first command signal when the actual acceleration signal is greater than the reference acceleration signal and generating a second command signal when the actual acceleration signal is smaller than the reference acceleration signal. The first command signal is fed to a first vehicle speed comparator means to render it operative. The second command signal is fed to a second vehicle comparator means to render same operative. Each of the first and second comparator means compares the vehicle speed signal with a set of reference vehicle speeds for generating a plurality of patterns of signals that indicate a corresponding plurality of lock-up ranges.
    • 一种锁止式自动变速器的锁止控制系统。 负载检测电路产生指示基准加速度的基准加速度信号和表示机动车辆的实际加速度的实际加速度信号。 当实际加速度信号大于参考加速度信号时,该电路将实际加速度信号与参考加速度信号进行比较,以产生第一命令信号,并且当实际加速度信号小于参考加速度信号时产生第二命令信号。 第一命令信号被馈送到第一车速比较器装置以使其可操作。 第二命令信号被馈送到第二车辆比较器装置以使其相同的操作。 第一和第二比较器装置中的每一个将车速信号与用于产生指示相应的多个锁定范围的多个信号模式的一组参考车辆速度进行比较。
