Abstract: A system utilizing Doppler radar for indication of vehicle speed at the time of a brake application and the stopping distance for that particular brake application. The output from the Doppler radar is a frequency that is directly related to the velocity of the vehicle with respect to ground. By the proper selection of the other constants, a given number of Hertz can correspond to a given velocity. Counting all the cycles from initial brake application until stopped and dividing by the appropriate value will give the total stopping distance. Dual counters that alternately record a velocity signal are applied. Light emitting diodes provide a visual readout of velocity and stopping distance.

Abstract: An adaptive braking system for an automotive vehicle is disclosed which includes a speed reacquisition feature which precludes termination of a brake pressure decay cycle until the controlled wheel attains a predetermined percentage of the angular velocity at which the wheel was rotating at the time that the decay cycle was initiated. The adaptive braking system includes the usual comparator which compares wheel acceleration to a predetermined reference level and generates a signal initiating a decay cycle when the wheel decelerates in excess of the reference level. The output signal of the comparator also enables a speed memory circuit which memorizes a predetermined percentage of the wheel speed. A comparator compares the instantaneous wheel speed during the decay cycle with the memorized value, and generates a signal which may maintain the decay cycle even though the wheel reaccelerates past an acceleration reference level which would normally terminate the decay cycle.
