The invention provides a hybrid electric vehicle generator control device. The hybrid electric vehicle generator control device comprises a control unit, a driving unit and a detection module, wherein the detection protection module is used for detecting position signals of a generator and current signals of the driving unit, outputting the position signals to the control unit, outputting operation current to the driving unit and outputting detection signals to the control unit; the control unit is used for receiving the detection signals output by the detection protection module and controlling the driving unit to drive the generator to operate. The hybrid electric vehicle generator control device is capable of effectively monitoring starting current when the generator of a hybrid electric vehicle is started, monitoring the operation current in the operation process, and carrying out corresponding protection according to detection results, so as to effectively ensure the performance of the generator controller and then ensure power supply and start-up stable operation of the hybrid electric vehicle.
