Abstract

PURPOSE:To provide an exact average value by obtaining an average speed from the time passed since the start of running of the car and its travel distance. CONSTITUTION:A range sensor 1 sends out a pulse at each certain travel distance, and the number of pulses is counted by a counter 2. A clock generator 3 sends out clock pulses, and the number of pulses corresponding to the time passed is counted by a counter 4. These numbers are calculated by a division calculator 5, and the results are shown at an average speedometer 6. When an ignition switch 8 is off, flip-flop 9b is at the reset position, Q is at L level, and the counters 2 and 4 are in the state of reset. The switch 8 turns to on position, the car starts running, and a pulse from the range sensor 1 reaches at terminal S of the flip-flop 9b. Then the counters 2 and 4 come out of the reset state, and start to count the average speed from that moment.
