Abstract
A vehicle controlling device wherein an output signal proportional to vehicle velocity obtained from a vehicle velocity detector and an output signal proportional to wheel velocity obtained from a wheel velocity detector are to be compared by a comparator and the slip state of the wheel is to be detected from the result of the comparison, thereby to control a brake mechanism, characterized in that an adder circuit is provided which adds an output signal proportional to a predetermined wheel velocity at a low vehicle running speed to the output signal obtained from the wheel velocity detector and that the output signal of the adder circuit and the output signal from the vehicle velocity detector are compared by the comparator to ensure accurate brake control at all vehicle speeds.
