  • Fail safe electrical brake control system for aircraft
    Patent number: 6183051
    Abstract: A brake-by-wire control system for aircraft brakes is presented. The system includes a hardware based discrete component control path and a software control path, the two operating in parallel. Each of the paths monitors the same input, with the hardware path being configured to enable the shutoff valve driver and the software path being configured to inhibit the shutoff valve driver, depending upon the status of the inputs. As a consequence, a failure in a single path in the braking system cannot enable the brake system so as to allow for inadvertent braking.
