  • Control system providing a variable impulse-like brake release and/or reapplication signal for wheel slip control
    Patent number: 3937525
    Abstract: An anti-wheel skid brake control system including a control circuit for providing an impulse-like control current in accordance with which electro-magnetic control valves are operated to either release or reapply brake pressure in an intermittent fashion. The impulse-like control current displays a predetermined pulse form that may vary in duration and interval with different stages of a digital counter whose output is continuously monitored by a decoding logic network. The variable, impulse-like control current provides for a gradual change in the brake pressure during the final stage of brake release or reapplication during a wheel skid to accordingly avoid overshooting of the brake release or reapplication pressure.
