The invention discloses a hydrogen fuel cell four-wheel hub motor drive external controller which comprises a processor, an angular velocity measurement module, a three-axial acceleration measurement module, a digital signal input module, an analog signal input module and a digital high-side output module, and is characterized in that the functions of a hub motor differential torque control TVCU and a vehicle control unit VCU are separated; the requirement for computing resource consumption of a controller chip is reduced, and the cost of the differential torque controller is saved; the functions of the controller are separated, so that the load unbalance risk on the CAN network is reduced; the control containing two control functions does not need to be developed again, and the development period is shortened; and the differential torque control of a hydrogen fuel cell full-power four-wheel hub motor driven automobile and a control function of the seamless integration of a whole automobile controller are rea
