Abstract

1535921 Brake control systems GIRLING Ltd 18 Dec 1975 [2 Jan 1975] 157/75 Heading F2F A braking system comprises a fluid pressure operable actuator controlled by electrically operated inlet and outlet valves 11 and 16 respectively, a brake demand signal generator 118 controlled by the operator, a brake feedback signal generator 119 generating a feedback signal indicative of braking force generated by the system, means 131 responsive to the demand and feedback signals to produce an error signal indicative of the difference therebetween and first and second pulse width modulation devices 133 and 134 controlled by the error signal to vary the respective voltages applied to the valves 11 and 16 in accordance with the magnitude of the error signal.
