Definitions

  • the revolutions of the vehicle wheels are transferred through a suitable reduction gearing to the numeral wheels of a mechanical counter and indicator to count and indicate the fare to be paid by the passenger for the distance traveled by the taxi.
  • the taximeters of this type employ a mechanical transmission comprising various mechanical moving parts or elements, especially gears, which are likely to wear, with resulting introduction of errors into calculation of fares.
  • the taxi fare is sometimes revised, and the revision will require a corresponding change in the reduction gear ratio.
  • the gear wheels must be changed and the work requires considerable time and money.
  • Taxicabs are of different sizes or classes which request different fares, and the taximeter adapted for use in taxis of one size or class cannot be used in taxis of a different size or class so that as many types of meters as there are sizes of taxicabs must be provided, with resulting increase in the manufacturing cost of taximeters.
  • the primary object of this invention is to provide a taximeter which is electronically con trolled.
  • Another object of this invention is to provide an electronically controlled taximeter, wherein electrical pulses are used to calculate the fare to be paid.
  • Another object of this invention is to provide an electronically controlled taximeter which calculates the fare to be paid on the distance and time basis.
  • the distance and time basis means that the taxi fare is calculated on the basis of both the distance or miles traveled during a trip and the time elapsed for the trip. That is, when the taxi is running at a normal speed, the meter is advanced on the basis of distance or mileage, while when the vehicle is stopped or slowed down, say, in heavy traffic, the meter is advanced on the basis of time elapsed.
  • Another object of this invention is to provide an electronically controlled taximeter wherein there are provided two kinds of pulses, that is, pulses for distance fare and pulses for time fare, so that they are selectively counted in accordance with the traveling condition of the vehicle so as to calculate the fare to be paid.
  • Still another object of the invention is to provide a taximeter which can be easily adapted to different rates of calculation of the fare by a simple change of circuit connections.
  • FIG. 1 is an electrical block diagram of one embodiment of the invention
  • FIG. 2 is a similar diagram showing a modification of a portion of FIG. 1;
  • FIG. 3 is a similar diagram showing a modification of a portion of FIG. 2.
  • the taxi fare is a composite amount consisting of the basic fare and the additional fare.
  • the basic fare is to be paid for a predetermined initial distance, say, 2 kilometers, from the start point of a trip.
  • the additional fare is the fare which is added to the basic fare for every predetermined unit additional distance, say, 420 meters over the basic distance. For travels in mountain regions or at midnight, the basic and additional fares are increased, or the distances covered by the basic and additional fares are shortened.
  • the above system of calculating the taxi fare is based on the distance traveled by the taxi.
  • the time spent for the travel is also taken into consideration in the fare calculating system. In this case, if the vehicle speed has slowed down below a predetermined commercially payable speed due to say, traffic congestion, an additional fare which would have resulted from taxi travel at the predetermined speed during that time is added to the fare for each predetermined unit period of time.
  • a pulse generator which produces a predetermined number of distance" pulses for every predetermined unit distance traveled by the vehicle.
  • the distance pulses are counted by a distance pulse counter which produces an output when it has counted a predetermined number of distance pulses, and the output is used to calculate and indicate the fare to be paid.
  • Another pulse generator produces a series of pulses having a fixed cycle. These pulses are counted by another pulse counter when the vehicle speed has become lower than a predetermined commercially payable speed. Whenever the counter has counted a predetermined number of the pulses, it produces an output, on the basis of which a time" fare is calculated and added to the distance fare.
  • a pulse generator PG is actuated is response to the rotation of a wheel of a taxi to produce a unit number ofdistance" pulses for every unit distance traveled by the vehicle.
  • the pulse generator produces 637 pulses for every 1 km traveled by the vehicle.
  • the cycle of the pulses correspond to the vehicle speed.
  • the distance pulses are applied as one input to an AND element A], on the one hand, and through a line Ll, a NOT element N2 and a NOR element NR2 as a reset input Re to a pulse counter C4, on the other hand.
  • the switch KR is closed for normal transport.
  • the normal transport means that the taxi with a passenger thereon travels under normal conditions and not in the mountain regions nor at midnight. Under normal conditions, when a passenger gets on a taxi, the driver pushes the switch KR as he starts the vehicle.
  • the signal from a source terminal E is applied as one input to AND elements A3 and AS through the switch KR and a line L2.
  • the signal is also applied through a line L3 to a preset gate G, whcih presets values 1 100 and l000 in binarycoded decimal notation in counters C5 and C6, respectively.
  • the counters C5 and C6 convert the binary codes to corresponding decimal numbers, which are applied to indicating tube driving circuits K1 and K2, respectively, so that the numerals l and 3 will be indicated on indicating tubes LT3 and LT4, respectively.
  • Four tubes LT1-LT4 are arranged side by side for indication of the fare to be paid.
  • the tubes When the tubes are not actuated, they show the nu meral or no numeral at all. When actuated, however, the tubes indicate 13, which can be expressed as L3 with a point between the two numerals or as 130 yen with a fifth tube always indicating 0 placed at the righthand side of the tube LT4.
  • the value 3 L3 or 130 yen indicates the basic fare for the basic distance. When the basic fare is to be changed, it is only necessary to simply change the reset values in the gate G.
  • Pulse counters Cl-C3 receive as a reset input the output of the NOR element NR1, so that when the output of the NOR element NR1 becomes 0 as previously mentioned, the reset input is removed from the counters C1-C3, whereupon the pulses from the pulse generator PG are applied through the AND element Al and an OR element 0R2 to the counter C1.
  • Each of the counters Cl-C3 is a hexadecimal counter comprising a series combination of four bi-stable elements, the output terminals 51-54, 85-88, 89-812 of which can be connected to exterior circuit elements.
  • the terminals Sl-Sl2 are selectively connectable to the terminals RSI-RS4.
  • the signals applied to the latter terminals are applied to the inputs of AND elements A3, A4, A5 and A6.
  • a memory element F3 comprising a flip-flop is normally reset, with its reset output R being applied as one input to the AND elements A3 and A4, so that when the counters C1-C3 have counted I274 pulses, the AND element A3 produces an output, which is applied through an OR element CR4 and a differentiator D to set memory flip-flops F1 and F3 and through an OR element 0R3 to reset the counters Cl-C3.
  • the set output S from the flip-flop F3 is applied as one input to AND elements A5 and A6.
  • the set output of the flip-flop F1 causes the output of the NOR element NR2 to disappear thereby removing the reset input Re from a counter C4, which is also a hexadecimal counter, whereupon the counter C4 starts counting clock pulses supplied thereto from an oscillator OSC.
  • the counter C4 has counted 15 pulses, it produces an output on the fifteenth output terminal, which is applied through an AND element A7 to set a flip-flop F2.
  • the set output of the flip-flop F2 is applied as one input to the NOR element NR2, so that no reset input is applied to the counter C4.
  • the set output of the flipflop F2 is also applied to 21 NOT element N3, the 0 output of which is then applied as one input to a NOR element NR3.
  • the clock pulses from the oscillator OSC are also applied to the other input of the NOR element NR3.
  • the NOR element NR3 becomes 0, so that with the two inputs having become 0, the NOR element NR3 produces an output, which resets the flip-flop F1 on the one hand and is applied to the input of the counter C5 on the other hand.
  • the NOR element NR3 again produces an output to be applied to the counter C5.
  • the output has a pulse width corresponding to the time that will elapse till the seventeenth pulse is produced by the oscillator OSC.
  • the counter C4 When the seventeenth pulse is produced, the counter C4 produces an output at the first output terminal. This output resets the flip-flop F2, so that the set output thereof having become 0 is applied to the NOT element N3. As a result, the NOT element N3 produces an output I to be applied to the NOR element NR3, so that the output pulses from the oscillator OSC can no longer cause NOR element NR3 to produce an output to be applied to the counter C5. This condition continues till the counter C4 produces an output at the fifteenth output terminal at the next time.
  • the flip-flop F2 when the flip-flop F2 is reset by the output on the first terminal of the counter C4, the set output of the flip-flop F2 having been rendered 0 is also applied to the NOR element NR2.
  • the pulse generator PG when the pulse generator PG produces an output pulse, the pulse is applied through the line L] to the NOT element N2, the output 0 of which is applied to the NOR element NR2, so that the element NR3 produces an output I to reset the counter C4.
  • the NOR element NR3 produces two pulses. These pulses are counted by the counters C5 and C6, and on the basis of the counts the indicator operating circuits K1 and K2 operate to change the indications on the indicator tubes LT3 and LT4 to, say, numerals l and 5, respectively.
  • This change of the indication has been resulted from the fact that the taxi has traveled the basic distance so that one unit fare of 20 yen has been added to the basic fare of 130 yen for a unit additional distance of 420 meters to be farther traveled by the taxi. Therefore, when the passenger gets off anywhere within the 420 meters over the basic 2 kilometers, he or she must pay 150 yen for the trip.
  • terminals RS3 To the terminals RS3 are connected those of the output terminals of the counters C1C3 at which an output appears when the counters C1-C3 have counted the number of pulses (say, 268 pulses) produced by the generator PG during the time the taxi travels one unit additional distance (420 meters). That is, the output terminals S3, S4 and S9 are connected to the terminals RS3.
  • the flip-flop F1 When the flip-flop F1 is set, two pulses are applied through the NOR element NR3 to the counter C5 in the same manner as when the basic distance was traveled, so that the indicator tubes LT3 and LT4 indicate the numerals l and 7, respectively. Now the fare has been raised to 170 yen. That is, when the taxi finished travel of the basic distance and one unit additional distance, the unit additional fare has been twice added to the basic fare. Likewise, every time one unit additional distance has been traveled, one unit additional fare is successively added to the fare accumulated until then.
  • the pulse generator PG produces pulses of a longer cycle or no pulses at all. Every time the generator PG produces an output pulse to be applied through the line L1 to the NOT element N2, the output of the NOT element disappears thereby removing the reset input form the counter C4.
  • the counter C4 produces an output at the fifteenth output terminal.
  • This output is applied through a line L4 to one input of the AND element A2, which then produces an output to be applied through the OR elememt 0R2 to the counter C1. That is, every time the counter C4 has counted 16 pulses from the oscillator OSC, one pulse is applied to the counter C1.
  • the output frequency of the oscillator OSC is so selected that if the speed of the taxi has been kept below a predetermined speed (that is, the minimum commercially payable speed) continuously for a predtermined period, say, 2 minutes and 30 seconds, 268 pulses are applied to the counter C1 during that time.
  • the frequency of the output pulses from the oscillator that satisfies the above condition is 28 c/s.
  • the condition is quite the same as if the taxi had traveled 420 meters. To put it in other words, it is presupposed that it takes 2 minutes and 30 seconds for the taxi to travel 420 meters at a normal speed, and if the taxi has run for 2.5 minutes at a speed lower than the predetermined minimum payable speed, one unit additional fare is added to the fare calculated until then on the assumption that the taxi has run 420 meters although actually it has not.
  • the taxi driver presses the push-button switch MR, whereupon the signal at the source terminal E is applied through a line L6 to the AND elements A4 and A6 on the one hand through a line L5 to the preset gate G on the other, whereupon the gate G presents values l0l0 and 1000 in binary-coded decimal notation in the counters C5 and C6, respectively, so that the indicator operating circuits [(1 and K2 actuate the tubes LT3 and LT4 to indicate numerals l and 5, respectively.
  • the counters C1-C3 begin to count the pulses from the pulse generator PG in the same manner as previously mentioned.
  • the basic distance that can be covered by the increased basic fare is 2.0l7 kilometers.
  • the number of pulses from the generator PG which corresponds to the distance is 1285.
  • the output terminals S1, S3, S9 and $11 of the counters C1-C3 are then connected to the terminals RS2.
  • an additional fare is added to the basic fare for every 350 meters the taxi farther travels.
  • the number of pulses from the generator PG which corresponds to the additional distance of 350 meters is 223.
  • the output terminals S1, S2, S3, S4, S5, S7 and S8 are then connected to the terminals RS4.
  • a waiting fare must be added to the distance" fare for every predetermined period of time the taxi waits. [n this case, the switch WB is pressed. If the taxi is provided with this switch WB, the previously mentioned time" fare addition system that is, to add to the distance fare an additional fare for every predetermined period of time elapsed when the taxi has been slowed down or stopped due to heavy traffic or like circumstances is not employed.
  • a switch SVW is provided in ganged relation to the switch WB. The switch SVW is normally kept in touch with a contact V.
  • the generator PG When the taxi has stopped at the request of the passenger, the generator PG necessarily stops production of output pulses, so that the output of the NOT element N2 is rendered l and remains to be I.
  • This continuous signal l is applied to the NOR element NR2, whereupon its output becomes to remove the reset signal Re from the counter C4.
  • the counter C4 Every time the counter C4 has counted 16 pulses from the oscillator, it produces an ouput on the th output terminal, which is applied as one input to the AND element A2.
  • the AND element A2 receives one pulse from the counter C4, it produces an output to be applied through the OR element 0R2 to the counters C1-C3.
  • the situation is quite the same as when the speed of the taxi has been lowered below the commercially payable level due to traffic congestion of the like circumstances, so that the fare is increased as the waiting time of the taxi passes by.
  • FIG. 2 shows an arrangement directed toward solving this problem.
  • the circuit shown in FIG. 2 corresponds to the left-hand portion of FIG. 1, with the remaining portion thereof not shown being substantially the same as in FIG. 1.
  • the pulses from the generator PG are applied to a differentiator D1, which produces a differentiated pulse corresponding to the leading edge of each pulse from the generator PG.
  • the differentiated pulse is applied as one input to an AND element 11 on the one hand and as a set input to a flip-flop F11 on the other.
  • the set output of the flip-flop F11 is applied as one input to an AND element A12, the output of which is applied as a set input to a flip-flop F12.
  • the set output of the flip-flop F12 is applied as the other input back to the AND element A11.
  • the output pulses from the generator PG are also applied to a NOT element N11, the output of which is differentiated by a differentiator D2.
  • the differentiated pulse corresponds to the trailing edge of the pulse from the generator PG and is applied as the other input to the AND element A12.
  • the output produced by the counter C4 when it has counted up is differentiated by a differentiator D3, the output of which resets the flipflop F11 and F12 and is also applied as one input to 0R1], to which the output of the AND element All is applied as the other input.
  • the output of the OR element ORll is applied as one input to the AND element Al, the output of which is applied to the counters C1-C3 shown in FIG. 1.
  • the pulses from the generator PG are differentiated by the differentiator D1, the output of which is applied as one input to the AND element All.
  • the AND element All produces no output.
  • the differentiated pulse from the differentiator D1 sets the flip-flop F11, so that its set output is applied as one input to the AND element A12.
  • the element A12 produces no output.
  • the differentiator D2 After the differentiated pulse from the differentiator D1 disappeared, the differentiator D2 produces an output pulse to be applied to the AND element A12, so that this element A12 produces an output to set the flip-flop F12. The set output of this flip-flop is applied as one input to the AND element A11. At this time, however, the other input (that is the differentiated pulse from the differentiator D1) to the AND element All has already disappeared, so that no output is produced by the AND element A1 1.
  • the pulse generator PG when the next pulse is produced by the pulse generator PG, the differentiated output from the differentiator D1 caused thereby is applied as one input to the AND element All, and with the set output of the flip-flop F12 at this time applied to the other input of the AND element A11, the element All produces an output to be applied through the OR element OR and the AND element A1 to the counters C1-C3.
  • the first pulse from the generator PG is not counted by the counters C1-C3.
  • the flip-flop F11 and F12 are not reset, so that the pulse is counted by the counters C1-C3.
  • the system will operate as follows. Suppose that by that time the flip-flops F11 and F12 have already been set. For simplicity of explanation, it is assumed that a pulse has been produced by the generator PG in coincidence with a pulse produced by the counter C4 when it has counted up. Between this time and the time the next pulse is produced by the generator PG, the counter C4 counts up to produce an output.
  • This count-up output is applied to the differentiator D3 and the differentiated output therefrom resets both the flip-flops F11 and F12, so that despite the next pulse from the generator PG applied to the AND element All, it produces no output pulse to be counted by the counters C1-C3.

  • the pulse cycle of the generator PG becomes longer than the count-up cycle of the counter C4
  • the pulses from the generator PG are not counted by the counters C1C3. That is, when the output of the NOR element NR2 resets the counter C4 through an OR element OR21, the same output actuates a timer T, the delay time of which is preset equal to the count-up cycle of the counter C4.
