Abstract

PURPOSE:To raise the precision of indication by indicating an approximate speed as a speed of a vehicle based on the speed of the vehicle at a normal time when the wheels of the vehicle rotate idly or slip on the occasion that the rotational speed of the wheel is indicated as the running speed of the vehicle. CONSTITUTION:The output of wheel speed detectors 1a-1d is converted to DC voltage proportional to the speed by F-V converters 2a-2d and transmitted to an approximate speed generator 4 and a braking power controlling circuit 8. At the time when normal braking is conducted, the reduction ratio alpha1 of vehicle-speed voltage V1 is smaller than the set reduction ratio alpha0 of discharge voltage V0 of a capacitor 6 settled by the discharge current of a discharge circuit 7 and by the capacity of the capacitor and the output V2 equals V1. At the time when braking is sharply, alpha1 becomes larger than alpha0, while the output V2 lowers according to the discharge voltage V0 starting from the wheel-speed voltage V1 when alpha1 equals alpha0 as the initial value and approximates the speed of the vehicle, and thus the approximate speed is indicated in an indicator 9 at the time of idling rotation or slippage.
