摘要： A comprehensive diagnostic for an active brake control system for automatically increasing braking at selected wheels of an automotive vehicle in response to detected vehicle turning maneuvers provides a hierarchy of diagnostic procedures for diagnosing local transducer and transducer circuit fault conditions, for diagnosing lack of correlation between transducers and subsystems, and for diagnosing low system level performance. Transducers or subsystems are isolated and indicated as the source of diagnosed low system performance to facilitate fault treatment procedures. Active brake control system authority is automatically reduced for at least the duration of diagnosed fault conditions.
