    • An electronic trip meter with an alarm for an automotive vehicle comprises a travelled distance sensing circuit, a memory circuit, a modification circuit, comparators, an alarm, first and second counters, a subtractor, a display circuit, and other auxiliary circuits. A plurality of sub distances defined by guide points along a course and a total distance of the course are respectively preset in the memory circuit and the second counter. The second counter output signal indicates a distance remaining to the goal of the course for displaying the remaining distance. The modification circuit output signal indicates a distance shorter than a sub distance while the first counter output signal indicates a distance actually travelled. When the vehicle travells over the distance shorter than the sub distance, the alarm is energized, by means of a comparison of the distances for informing the driver that a next guide point is near. Simultaneously, a distance remaining to the next guide point is displayed for a predetermined period of time.
    • 具有汽车警报的电子行程表包括行驶距离检测电路,存储电路,修改电路,比较器,报警器,第一和第二计数器,减法器,显示电路和其他辅助电路。 沿着课程的引导点和课程的总距离限定的多个子距离分别预设在存储器电路和第二计数器中。 第二计数器输出信号表示剩余距离的剩余距离。 修改电路输出信号表示比子距离短的距离,而第一计数器输出信号指示实际行进的距离。 当车辆行驶距离短于副距离的距离时,通过比较用于通知驾驶员下一个引导点靠近的距离来报警。 同时,在预定的时间段内显示剩余到下一个引导点的距离。

    • An electronic trip meter for a motor vehicle comprises an up-down counter, a memory circuit, display circuit, and other auxiliary circuits. The up-down counter produces an output signal indicative of a distance travelled by the vehicle by counting a number of pulses generated each time the vehicle travels a predetermined distance or a distance remaining to an objective point of a predetermined course by subtracting the travelled distance from a preset distance. The counting up and down functions of the up-down counter is manually controlled for compensating for a travelled distance along a wrong course. The output of the up-down counter is fed to the display circuit for displaying a distance indicated by the output signal thereof. A plurality of distances of legs of a predetermined course may be stored in the memory circuit so that each distance is fed to the up-down counter as the predetermined distance.
    • 一种用于机动车辆的电子行程表包括升降计数器,存储电路,显示电路和其它辅助电路。 升降计数器产生指示车辆行进的距离的输出信号,该方法通过计算每当车辆行驶预定距离或剩余到预定航向的目标点的距离时产生的脉冲数,从而减去行驶距离 预设距离。 手动控制升降计数器的上下计数功能,以补偿沿错误路线行驶的距离。 升降计数器的输出被馈送到显示电路,以显示由其输出信号指示的距离。 预定路线的多条腿的距离可以存储在存储器电路中,使得每个距离作为预定距离被馈送到升降计数器。

    • An electronic trip meter for an automotive vehicle comprises an up-down counter, a memory circuit, an adder-subtractor, a display circuit, and other auxiliary circuits. The up-down counter produces a signal indicative of a remaining distance to a goal by subtracting an actually travelled distance from a preset distance between two points for displaying the remaining distance by the display circuit. When the vehicle reaches the goal, the adder-subtractor produces a signal indicative of the actually travelled distance in accordance with the output signals of the up-down counter and the memory circuit in which the preset distance is stored. The adder-subtractor output signal is then fed to the up-down counter for displaying the actual distance between the two points and to the memory circuit for correcting the preset distance whereby a remaining distance to the starting point in a return trip is easily and accurately obtained. The trip meter may be also utilized for a trip beyond the goal.
    • 一种用于机动车辆的电子行程表包括一个升降计数器,一个存储电路,一个加法器 - 减法器,一个显示电路和其它辅助电路。 升降计数器通过从显示电路显示剩余距离的两个点之间的预设距离减去实际行进的距离来产生指示到目标的剩余距离的信号。 当车辆到达目标时,加法器 - 减法器根据存储预设距离的升降计数器和存储电路的输出信号产生指示实际行进距离的信号。 然后,加减法器输出信号被馈送到升降计数器,用于显示两点之间的实际距离和存储电路,用于校正预设距离,从而在回程中起始点的剩余距离容易且准确 获得。 行程表也可以用于超出目标的行程。
