Abstract
A control circuit for regulating the application and release of brake force in an electric brake. A pulse width modulator presents an output signal of regulatable duty cycle to power drivers connected to the electric motors of the brake. A control circuit regulates the direction of current flow through the motors to achieve either brake application or brake release. The output of the pulse width modulator is set by the position of the brake pedal or by a signal which is a function of the correlation betwen brake torque and the position of the brake pedal, whichever is larger.
