Abstract
PURPOSE: To lessen the cumulative error of integrated mileage for a long period by a method wherein the number of effective figures of a presettable counter and a nonvolatile memory is made larger by one figure than the number of effective figures of a digital indicator.
CONSTITUTION: When an ignition switch 1 is turned ON, the stored data of each figure of the nonvolatile memory 4 are preset in each figure of the presettable counter 3. With these data being used as an initial value, a mileage pulse signal SD per 0.01km after the start of traveling is further counted and a counted value in six figures of higher rank effective for indication is indicated in the digital indicator 6 through the intermediary of a decoder-driver circuit 5. When the ignition switch is turned OFF, a timing control circuit 2 outputs a pulse signal Ps by the voltage of a voltage retainer 7, while the nonvolatile memory 4 memorizes the counted value of the presettable counter 3 per 0.01km at that time.
