Method and system for performing fail-safe operation for anti-skid automotive brake control system having a plurality of controllers independently operable to others

摘要

An anti-skid brake control system for an automotive brake system includes a plurality of controllers respectively adapted to perform anti-skid brake control operations for corresponding vehicular brake systems. A fail-safe system for the anti-skid brake control system includes a detector provided in each of the controllers, which detects malfunction of one or more components of the corresponding controller and/or the corresponding brake system, a disabling means responsive to malfunction of the component or components in the anti-skid brake control system for blocking electric power to an actuator controlling a pressure control valve, and means associated with the actuator and responsive to operation of the disabling means to operate the actuator to an application mode position in which the pressure control valve allows manual control of the brakes. Each of the controllers are associated to the others for performing fail-safe operation when one of the detectors in one of the controllers detects failure of anti-skid brake control operations in the corresponding controller and/or brake system.
