Abstract
PURPOSE:To keep off any increase in a braking distancce at a rough road, by constituting a braking pressure warming signal so as to be given to a hydraulic control circuit at a time when frequency in the braking pressure warming signal out of a discrimination circuit is more than the setting value or a pluse separation space is below the setting one. CONSTITUTION:The detected value of a wheel speed detector 1 is converted into a voltage signal with a frequency-voltage converter 2, and this voltage signal is inputted into both of a discrimination circuit 3 and an operation circuit 4. And, at this discrimination circuit 3, a fact that whether there is a possibility of locking a wheel or not is judged and outputs a braking pressure warming signal from one side of output terminals 3a. In this case, one side of these output terminals 3a is connected each to one side of input terminals of an AND gate 9 and an input terminal of a monostable circuit 10. And, a filter circuit 11 outputting only such a braking pressure warming signal as being more than the specified time in a pulse separation space. With this constitution, the braking pressure warming signal outputted from the discrimination circuit 3 at a time when there is no possibility of locking the wheel is prevented from being given to a hydraulic control circuit 6.
