The invention provides an intelligent wristband for identifying a passenger and a driver and a method and belongs to the field of intelligent wearabld equipment. The intelligent wristband comprises awristband belt, a wristband shell body and a control circuit board, wherein the wristband shell body is provided with the wristband belt; the control circuit board is embedded into the wristband shellbody; a power supply module, a sensor module, a position tracking module, a display touch module, a wireless communication module, a vibration module, a storage module and a microprocessor are distributed on the control circuit board; the position tracking module of the wristband is used for judging whether a user sits on a vehicle or not and a sensor is used for judging whether the user has thesuspected motion of rotating a steering wheel or not. Messages are pushed to a mobile terminal for a plurality of times to inquire whether the user judges correctly or not. After a plurality of timesof data acquisition are carried out, a BP neural network is applied to self-learning, and accurate identification on a driving state of the user can be realized, so that a theoretical foundation is provided for identifying a fatigue state by the wristband in the future.
