    • A shift indicator system for a vehicle comprises an engine speed sensor, an engine speed comparator for comparing the engine speed detected by the engine speed sensor with a preset value, an indicator which provides an indication for directing upshifting when the engine speed is not lower than the preset value, a delay circuit which inhibits the indicator from providing the indication for directing upshifting until the engine speed continues to be not lower than the preset value for a predetermined time interval, an engine speed increasing rate detector for detecting the rate of increase of the engine speed, an engine load increasing rate detector for detecting the rate of increase of the engine load, and a delay time setting circuit which receives the outputs of the engine speed increasing rate detector and the engine load increasing rate detector, and makes the predetermined time interval shorter as the engine speed increasing rate increases and longer as the engine load increasing rate increases.
    • 用于车辆的换档指示器系统包括发动机速度传感器,用于将由发动机转速传感器检测到的发动机转速与预设值进行比较的发动机转速比较器,当发动机转速不低于时提供指示换档指示的指示器 所述预设值,延迟电路,其禁止所述指示器提供用于引导升档的指示,直到所述发动机转速在预定时间间隔内持续不低于所述预设值;发动机速度增加率检测器,用于检测所述预设值, 发动机转速,用于检测发动机负荷增加率的发动机负载增加率检测器,以及接收发动机增速率检测器和发动机负荷增加率检测器的输出的延迟时间设定电路, 发动机转速增加率随着发动机负荷的增加而增加,时间间隔越短 吃了增加。
