Abstract
The brake pedal force is amplified by an electric motor acting through a gear set which converts rotary motion and torque from the motor into linear motion and force to energize the master cylinder piston. The push rod forces are sensed, amplified, reduced and modulated by electronic means. The electric motor disengages from the gear set at rest or if there is an electrical failure, so that there is a manual mode of operation available when necessary.
