Abstract: An adaptive braking system for a vehicle having fluid pressure operated brakes includes a skid detecting circuit for generating a signal when an incipient skidding condition is detected, a pressure command generator which is responsive to the skid detecting signal for generating a pressure command signal proportional to the optimum fluid pressure level in the vehicle's brakes, and a duty cycle translator responsive to the pressure command signal to actuate the brake pressure modulator. Of course, since the pressure level in the vehicle brakes cannot drop below zero, the value of the pressure command signal generated by the pressure command generator cannot drop below a predetermined level. If the skid detecting circuit continues to generate a signal indicating an incipient skidding condition after the pressure command signal is at its lowest level, the subsequent brake pressure increase which is normally initiated upon termination of the skid detecting signal is delayed for a time period which is a function of the time period in which the skid detecting signal was generated after the value of the pressure command signal had dropped to the lowest permissible level.

Abstract: An adaptive braking system for a vehicle having fluid pressure operated brakes includes a skid detecting circuit for generating a skid detecting signal when an incipient skidding condition is detected, a pressure command generator which is responsive to the skid detecting signal for generating a pressure command signal, and a duty cycle translator responsive to the pressure command signal to actuate the brake pressure modulator. The duty cycle translator includes a circuit which generates a signal modeling the actual pressure level in the vehicle brake actuators. Since the modulator is actuated by a solenoid which is powered by the vehicle electrical supply, the opening and closing times of the solenoid will vary as a function of the power output of the vehicle power supply, which can vary over a substantial range depending upon ambient temperature and upon the strength of the vehicle battery. Accordingly, the duty cycle translator includes a circuit which models the opening and closing times of the solenoid actuators and the reaction time of the mechanical valve components to thereby more closely model the actual pressure level in the vehicle brake actuators.
