Abstract

PURPOSE: To enable vehicle speed display to well respond to all accelerations and decelerations and perform flicker-free display by determining the number of the pulses produced per revolution of a vehicle sensor from the time required for the maximum acceleration between vehicle speeds 0 to 30Km/h and the pitch of analog display elements.
CONSTITUTION: This is the apparatus of counting the vehicle speed pulses produced from a vehicle sensor 1 with counters 3, 30 and having these digitally and analogicially displayed, wherein the number P of the pulses produced per revolution of the vehicle sensor at which all the display elements between 0 to 30Km/h can respond within the time t is calculated from the time t required for the maximum acceleration from vehicle speed 0 up to 30Km/h and the pitch S of the display elements of the analog display part, by which the specifications of the vehicle speed sensor are determined and the counter count time is so set that one pulse becomes the display of 1Km/h in the case of digital display and one pulse becomes the display of 1 segment in the case of analog display.
