Abstract: The present invention belongs to the technical field of electric automobiles and particularly relates to a fault tolerance decision-making method and system for sensor failure of a vehicular wheel hub driving system. The method comprises a current sensor failure diagnostic process, a position/velocity sensor failure diagnostic process and a selection process for a wheel hub motor fault tolerance control method. The system comprises a current sensor failure diagnostic module, a position/velocity sensor failure diagnostic module and a selection module for a wheel hub motor fault tolerance control method. The position/velocity sensor failure diagnostic module further comprises a fault tolerance control switching module. The present invention has the characteristics of establishing a control strategy decision-making mechanism oriented to random complicated current and position sensor failure conditions and designing a multivariable decision-making model according to a vehicular velocity range and a sensor fault condition to realize a fault tolerance control process compatible with a full velocity range.
