Circuit for preventing the wheel velocity from exceeding the vehicle velocity in vehicles with antilocking brake systems

摘要

A switching circuit for preventing the velocity of the rotating wheels from exceeding the velocity of the moving vehicle in an anti-skid vehicular braking system. The switching circuit includes a first threshold device for generating deceleration and acceleration control signals and a second threshold device for generating positive and negative slip control signals. A logic circuit for evaluating the control signals and controlling the brake pressure and switching devices being activated by a positive slip control signal for blocking the first threshold device from generating the deceleration and acceleration signals and which blocking can be eliminated by the presence of a negative slip control signal.
