    摘要: 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.

    摘要: 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.

    摘要: 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.

    摘要: A navigation instrument for roadway vehicles comprises a first counter for counting pulses each occurring in response to the vehicle moving a predetermined distance to detect the distance travelled from the starting point of a trip, a second counter for counting clock pulses to detect the time elapsed from the start of the vehicle. A microcomputer or digital circuitry is provided to compute on the data received from the first and second counters to derive an output data representative of the average speed of the vehicle over the distance so far travelled and to compare the computed average speed with a desired speed to detect the deviation of the actual average speed from the reference. A comparator is provided to detect when this deviation exceeds a predetermined value to generate a warning signal to alert the vehicle driver to correct the vehicle speed.

    摘要: A navigation instrument for use with a roadway vehicle comprises an arithmetic means producing three data signals showing the average speed of the vehicle, the deviation of the travelling distance from a scheduled one, and the deviation of the travelling time from a scheduled one, and a display means for displaying the three data sequentially fed from the arithmetic means through a signal selector means. The arithmetic means includes travelling distance/time deviation accumulating means for adding the deviation of the travelling distance/time with respect to the average speed initially set to the deviations of the travelling distance/time whenever the average speed is altered. Thus, the navigation instrument of the present invention makes it possible to calculate and display the travelling distance/time deviation accumulated value when the average speed of the vehicle is altered on the way of vehicle travelling.

    摘要: A navigation instrument comprises a first counter for counting travelling distance from a start point, a second counter for counting travelling time from starting, a means for setting a scheduled average vehicle speed, an arithmetic means for calculating average vehicle speed, the deviation of travelling distance from the scheduled distance and the deviation of travelling time from the scheduled time, and a display means for displaying the result of calculation. The first counter is capable of subtractively counting travelling distance in response to switching operation of a switching means which is incorporated to the first counter. The first counter is also incorporated with a means for stopping navigating operation which is operative when the first counter counts down the travelling distance until a given value.
