Brake controller
 A vehicle brake controller provided with an electronic data processor to keep uniform the relationship between the pedal effort and the effectiveness of the brake independently of the change in various driving conditions. Data processor stores an optimum relationship, processes the signals from the sensors, computes a desired deceleration and gives a control signal to the control valve so that the actual deceleration will be equal to the desired deceleration.
