  • Patent number: 4402057
    Abstract: A reference check bit pattern is stored in a nonvolatile storage medium of a vehicle-mounted microcomputer. A portion of a volatile storage medium is allocated for the purpose of storing the reference check bits. The microcomputer is programmed to compare the check bits stored in both the volatile and nonvolatile storage mediums. In response to a command signal, a mismatch is detected between the reference check bits of the volatile and nonvolatile mediums to indicate that data stored in the volatile memory have failed due to a power outage. The failed check data of the volatile memory is rewritten with the reference check data in the nonvolatile memory for later comparison. At the same time all data stored in the remaining portion of the volatile memory is erased so the remaining portion can accept a set of fresh input data. When a match occurs the computer proceeds with the normal computing functions.

  • Patent number: 4371940
    Abstract: 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.

  • Patent number: 4318312
    Abstract: A gear shift control system for an automatic transmission comprises an air flow sensor for sensing the quantity of air taken into an internal combustion engine and supplying a corresponding electrical signal to a differentiator which provides a derivative of the sensed intake air quantity. A vehicle speed sensor senses the speed of rotation of the engine crankshaft to generate a corresponding signal. A gear shift decision circuit is receptive of signals from the air flow sensor and vehicle speed sensor to define a gear shift control line on a two-dimensional coordinate system as a function of the received input signals on respective coordinate axes. The derivative of the sensed air quantity is used to shift the gear shift control line to a higher speed side of the coordinate system to permit the transmission to effect downshift operation.

  • Patent number: 4307452
    Abstract: A fuel consumption measuring apparatus for an internal combustion engine equipped with an electromagnetic fuel injection valve, comprising a fuel injection control means which calculates a proper value of fuel to be injected into the engine, and which then corrects this value in accordance with the characteristics of the electromagnetic fuel injection valve and controls the valve thereby, and a totalling means, which, in synchronization with the signals for controlling the valve, totals the values of the amount of fuel to be injected. In an embodiment, the totalling means is capable of subtracting a first predetermined value from the total held therein, and the apparatus further comprises a decision means which at regular time intervals judges whether the totalled value in the totalling means is greater than a second predetermined value or not; and, if it is, outputs an output pulse signal and also controls the totalling means to cause it to perform the subtraction.

  • Patent number: 4291373
    Abstract: A navigation information announcing system for a motor vehicle comprises a tape player, circuitry for measuring the distance actually travelled by the vehicle, circuitry for reproducing distance information pre-recorded on a magnetic tape, and a comparator. A distance indicated by a reproduced datum from a magnetic tape is compared with the distance actually travelled so that the tape player performs a pause operation until the two distances equal each other. When these distances equal each other, the normal playback operation is reestablished so as to reproduce oral information pre-recorded on the magnetic tape, supplying the vehicle driver with directional information.

  • Patent number: 4263657
    Abstract: 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.

  • Patent number: 4250402
    Abstract: 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.

  • Patent number: 4244514
    Abstract: 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.

  • Patent number: 4121545
    Abstract: An electronic fuel injection control apparatus is provided with a first sensor to determine the volume of intake air and a second sensor providing an electrical signal the magnitude of which is related to the engine speed. The detected air volume is translated into a corresponding pivotal movement. A variable resistance element is arranged to alter its value in accordance with the pivotal movement. The engine speed related signal is connected to the end terminals of the resistance element to develop a voltage representing the engine speed. The variation of the resistance value produces corresponding variation in voltage across the output terminals of the resistance. The output voltage is thus related both to the engine speed and intake air volume, and used to modulate the duration of a pulse produced per engine revolution to provide an injection control signal.
