摘要： A redundant architecture for a brake-by-wire system is provided. The system includes a pressure source; at least one brake actuator for exerting a braking force on a wheel as a result of pressure provided by the pressure source; at least one servo valve for controlling an amount of pressure provided from the pressure source to the at least one brake actuator in response to a servo valve command signal; a shutoff valve in line with the at least one servo valve for preventing pressure from the pressure source from being provided to the at least one brake actuator in response to a shutoff valve command signal; a processor which executes code in order to carry out brake control operations, the processor outputting the servo command signal and the shutoff valve command signal in response to system inputs provided to the processor; a shutoff valve enable device for performing brake control operations redundant at least in part with the processor and based on the system inputs, and selectively enabling shutoff valve command signals from the processor to be provided to the shutoff valve based on the redundant brake control operations.
