Zusammenfassung:	PURPOSE:To calculate the traveling distance of vehicle accurately by suppressing traveling error due to slip as low as possible thereby suppressing error in calculation. CONSTITUTION:FV converting circuits 2a, 2b convert rotational 7 pulses Al, A2 fed from front and rear wheels, respectively, into voltages B1, B2 corresponding to the frequency. i.e., the rotational speed. The voltages B1, B2 are then converted through wheel diameter multiplying circuits 4a, 4b into speed correspondence voltages C1, C2 which are compared with each other through a high priority circuit 6 and then the higher voltage is selected and fed, as an output voltage D, to a VF converting circuit 8. The output voltage D is converted through the VF converting circuit 8 into a distance pulse E having frequency proportional to the voltage value. The distance pulse E is then counted by an accumulating circuit 10 for a predetermined distance measuring time thus calculating the traveling distance.
